This response letter was written to address your comment e-mailed to the city on August 3, 2012. Your comment from your letter is shown in italics, followed by the City's response. Comment: While mitigation measure BIO-2 partially addresses our concerns, the Wildlife Agencies recommend a separate mitigation measure that requires the contractor to develop and submit a drilUng mud control plan as described in the project's construction plans (page 2, HDD Notes) that focuses on the minimization of direct, indirect, and cumulative impacts that may occur from hydrofractures associated with directional drilling. The drilling mud control plan at a minimum should include the following: 1. Techniques to reduce potential for hydrofracture and inadvertent returns that could pollute Agua Hedionda Lagoon: a) Sufficient earth cover should be used to increase resistance to hydrofracture. b) An adequately dense drilling fluid should be used to avoid travel of dniling fluid in the porous sands. c) The bore should be conducted in a manner that avoids collapse. d) Borehole pressure should be maintained at levels low enough to avoid hydrofracture. e) Reaming and pullback rates should be maintained at rates slow enough to avoid overpressurization of the bore. 1635 Faraday Avenue, Carisbad, CA 92008-7314 T 760-602-4600 F 760-602-8559 © RWI EIA 12-01 - VANCOUVER STRfPT HDD SEWER EXTENSION ^ August 7, 2012 Page 2 f) The surface above the vicinity of the drill head should be visually monitored for surface evidence of hydrofracture. g) Drilling methods should be modified to suite site conditions such that hydrofracture does not occur 2. Hydrofractures should be cleaned immediately after they occur. Necessary response equipment should be readily accessible and in good working order 3. All field personnel should understand their responsibility for timely reporting of hydrofractures. Response: The city has added mitigation measure BlO-5 to the project's Mitigation Monitoring and Reporting Program (MMRP) and EIA Part 11 documents to address your concerns in order to avoid impacts to various waterways during construction due to the possibility of hydrofractures associated with horizontal directional drilling (HDD). The mitigation measure includes construction notes on the project plans, which shall state that the contractor shall submit and implement a "frac-out" plan. The plan at a minimum shall include No. 1-3 that you listed in your letter. Thank you again for your comment.

This response letter was written to address your comments in your letter dated July 23, 2012. Your comments from your letter are shown in italics, followed by the city's response. Comment: Mitigation measure BIO-3 states that "trees in the Project area shall be removed to prevent potential impacts due to nesting activities." Please identify which trees could potentially be removed and discuss if those identified trees are protected by local ordinances and/or have potential suitable habitat to support the federally threatened California gnatcatcher (Polioptila californica California) and other migratory and raptor bird species. Response: Mitigation measure BlO-3 states that, "To avoid potential impacts, trees shall be removed outside of the breeding season of local raptor species (trees shall be removed between September 15 and January 15)." Eucalyptus trees currently are adjacent to the sewer lift station; however, the project is not expected to remove any trees from the surrounding area. Comment: As part of the Section 106 compliance under the CWSRF Program, Native American consultant is required. Please include documentation of all contact made with the tribes affiliated with the Project area. A list ofthe Native American tribes can be obtained from the Native Amencan Heritage Commission (NACH). Response: The city is not applying for CWSRF funding; therefore, no Section 106 compliance is required. The city has contacted the local tribes for input on the project. See the attached letter from Rose Duro, Rincon Culture Committee Chair, dated July 27, 2012. Furthermore, mitigation measure CUL-2 states in part, "Prior to the commencement of ground disturbing activities, the project developer shall retain the services ofa Native American monitor." Comment: The Hazards and Hazardous Matenals section refers to Best management Practices (BMPs) that will be used to "minimize the potential for release of fuel or lubricants, and will clean up bentonite slurry in the event ofan accidental release." Please identify the appropriate BMPs that could potentially be used in the event ofan accidental spill or release of hazardous materials. 1635 Faraday Avenue, Carlsbad, CA 92008-7314 T 760-602-4600 F 760-602-8559 © EIA 12-01 - VANCOUVER STREET HDD SEWER EXTENSION August 7, 2012 Page 2 Response: The city has added mitigation measure BlO-5 to the project's Mitigation Monitoring and Reporting Program (MMRP) and EIA Part 11 documents to address concerns due to the possibility of hydrofractures associated with horizontal directional drilling (HDD).

This response letter was written to address your comments e-mailed to the city on July 30, 2012. Each comment from your letter is shown in italics, followed by the City's response. Comment: Hydroseed plant mix. This reseeding was not called out as a mitigation measure so it is unclear exactly what area will be covered. In addition to the area where the old tower is being removed, this should include all areas where there is ground disturbance where it is not already bare dirt. This should include equipment storage areas and possibly others. Several invasive plant species are shown as being present on the project site. Ground disturbance makes it easier for these species to spread. Reseeding will help reduce such potential indirect impacts from ground disturbance associated with the project. Plant mix to be used for hydroseeding was not specified. In addition to assuring that no plants on the CA-IPC list are used this also needs to specify: plants on the SD Museum of Natural History list of plants of local concern are also avoided, seeds will be locally sourced from San Diego County to reduce genetic contamination. Response: The project description, on page 1 of the draft EIA Part 11, states that the existing sewer lift station area will be hydroseeded with a native seed mix. Staff will clarify under the project description, and add to the General Notes section of the plans, that all disturbed areas within the preserve shall be hydroseeded using seeds locally sourced from San Diego County and that no exotic invasive species, which are defined by the California Invasive Plant Council (CA-IPC), as those with moderate to high risk, or other non-native species shown to be locally invasive. The only other area that will be disturbed is the grass area within the park, which will be reseeded with grass seed. Furthermore, the contractor will be required to provide the city an Equipment Staging and Traffic Control Plan for approval, as stated on page 2 of the draft EIA Part 11. Staff will include this under the General Notes section ofthe plans. 1635 Faraday Avenue, Carisbad, CA 92008-7314 T 760-602-4600 F 760-602-8559 © *n Elj| 11«0^-VANCOUVER STR&Et HDD SEWER EXTENSION Aug|sf ^2pl2 * " Page 2 Comment: - Potential pipe "welding" impacts. We found no discussion of potential air quality impacts from the on-site "welding" of the pvc pipe. Such materials can emit toxic fumes under some circumstances. Please explain how such potential fumes are being addressed. Response: The fusion process of HDPE is done at 425 to 450 degrees Fahrenheit, where the two surfaces of the high density polyethylene (HDPE) pipes become molten and then pressed together. There are no solvents used in this process and, therefore, there is no emission from combustion of material. The process is often executed and demonstrated indoors with no special ventilation necessary. Comment: - Wo GHG impacts discussion. We realize that this type of project will be producing a relatively small amount of GHG (2,150 Ibs/day). The air quality analysis provided the computation for volume produced and included this statement "Emissions of C02 are included for global climate change discussion." But no such discussion was included in the MND. Please add discussion about global climate change impacts and analysis as to whether 2,150 Ibs/day is significant. Response: Section Vll. Greenhouse Gas Emissions discusses the project's potential to contribute to greenhouse gas (GHG) emissions and global climate change. GHG emissions thresholds are measured in metric tons per year, rather than pounds per day because the South Coast Air Quality Management District guidelines use metric tons per year as their measurement unit for significance thresholds. Furthermore, the issue of climate change is a global phenomenon, and a unit such as pounds per day is not adequate to address the scale of the topic. Page 28 of the Draft IS/MND states, "The short-term GHG emissions—C02 equivalent (over the approximately 3 month project period)—were estimated at 305 metric tons using the CalEEMod model in conjunction with estimated vehicle/equipment usage schedules ... The GHG emissions from the proposed project are well below significance thresholds (e.g., 10,000 metric tons/year for construction included in the South Coast Air Quality Management District suggested guidelines, December 2008; 7,000 metric tons/year by the CARB, October 2008). As a result, the project's contribution to overall GHG emissions and GCC impacts would be less than significant." Thank you again for your comments.

As a funding agency and a state agency with jurisdiction by law to preserve, enhance, and restore the quality of California's water resources, the State Water Resources Control Board (State Water Board) is providing the following information and comments for the IS/MND prepared for the Project. Please provide us with the following documents applicable to the Project if the City decides to pursue CWSRF financing: (1) one copy ofthe draft and final IS/MND, (2) the resolution adopting the IS/MND and a Mitigation Monitoring and Reporting Program (MMRP), along with any California Environmental Quality Act (CEQA) findings, (3) all comments received during the review period and the City's response to those comments, (4) the adopted MMRP, and (5) the Notice of Determination filed with the San Diego County Clerk and the Governor's Office of Planning and Research, State Clearinghouse. In addition, we would appreciate notices of any hearings or meetings held regarding environmental review of any projects to be funded by the State Water Board. The State Water Board, Division of Financial Assistance, is responsible for administering the CWSRF Program. The primary purpose for the CWSRF Program is to implement the Clean Water Act and various state laws by providing financial assistance for wastewater treatment facilities necessary to prevent water pollution, recycle water, correct nonpoint source and storm drainage pollution problems, provide for estuary enhancement, and thereby protect and promote health, safety and welfare ofthe inhabitants ofthe state. The CWSRF Program provides low- interest funding equal to one-half of the most recent State General Obligation Bond Rates with a 20-year term. Applications are accepted and processed continuously. Please refer to the State Water Board's CWSRF website at: www.waterboards.ca.qov/water issues/programs/grants loans/srf/index.shtml. The CWSRF Program is partially funded by the United States Environmental Protection Agency and requires additional "CEQA-Plus" environmental documentation and review. Four enclosures are included that further explain the CWSRF Program environmental review process and the additional federal requirements. The State Water Board is required to consult directly with agencies responsible for implementing federal environmental laws and regulations. Any environmental issues raised by federal agencies or their representatives will need to be resolved prior to State Water Board approval of a CWSRF financing commitment for the Project. For further information on the CWSRF Program, please contact Mr. Ahmad Kashkoli, at (916) 341-5855. It is important to note that prior to a CWSRF financing commitment, projects are subject to provisions of the Federal Endangered Species Act (ESA) and must obtain Section 7 clearance from the United States Department ofthe Interior, Fish and Wildlife Service (USFWS), and/or the United States Department of Commerce National Oceanic and Atmospheric Administration, National Marine Fisheries Service (NMFS), for any potential effects to special status species. Please be advised that the State Water Board will consult with USFWS, and/or NMFS regarding all federal special status species that the Project has the potential to impact if the Project is to be funded under the CWSRF Program. The City will need to identify whether the Project will involve any direct effects from construction activities, or indirect effects such as growth inducement, that may affect federally listed threatened, endangered, or candidate species that are known, or have a potential to occur on-site, in the surrounding areas, or in the service area, and to identify applicable conservation measures to reduce such effects. In addition, CWSRF projects must comply with federal laws pertaining to cultural resources, specifically Section 106 ofthe National Historic Preservation Act. The State Water Board has responsibility for ensuring compliance with Section 106 and must consult directly with the California State Historic Preservation Officer (SHPO). SHPO consultation is initiated when sufficient information is provided by the CWSRF applicant. A consultant that meets the Secretary ofthe Interior's Professional Qualifications Standards (www.cr.nps.gov/local-law/arch stnds 9.htm) must be retained to prepare a Section 106 compliance report. Note that the City will need to identify the Area of Potential Effects (APE), including construction and staging areas, and the depth of any excavation. The APE is three-dimensional and includes all areas that may be affected by the Project. The APE includes the surface area and extends below ground to the depth of any Project excavations. A records search request from the California Historical Resources Information System (CHRIS) should be made for an area larger than the APE. The appropriate area varies for different projects but should be drawn large enough to provide information on what types of sites may exist in the vicinity. Other federal requirements pertinent to the Project under the CWSRF Program include the following: A. Compliance with the Federal Clean Air Act: (a) Provide air quality studies that may have been done for the Project; and (b) if the Project is in a nonattainment area or attainment area subject to a maintenance plan; (i) provide a summary ofthe estimated emissions (in tons per year) that are expected from both the construction and operation of the Project for each federal criteria pollutant in a nonattainment or maintenance area, and indicate ifthe nonattainment designation is moderate, serious, or severe (if applicable); (ii) if emissions are above the federal de minimis levels, but the Project is sized to meet only the needs of current population projections that are used in the approved State Implementation Plan for air quality, quantitatively indicate how the proposed capacity increase was calculated using population projections. B. Protection of Wetlands: Identify any portion of the proposed Project area that should be evaluated for wetlands or United States waters delineation by the United States Army Corps of Engineers (USACE), or requires a permit from the USACE, and identify the status of coordination with the USACE. C. Compliance with the Migratory Bird Treaty Act: List any birds protected under this act that may be impacted by the Project and identify conservation measures to minimize impacts. D. Compliance with the Flood Plain Management Act: Identify whether or not the Project is in a Flood Management Zone and include a copy of the Federal Emergency Management Agency flood zone maps for the area. E. Compliance with the Wild and Scenic Rivers Act: Identify whether or not any Wild and Scenic Rivers would be potentially impacted by the Project and include conservation measures to minimize such impacts. Following are specific comments on the City's draft IS/MND: 1. Mitigation measure BIO-3 states that "trees in the Project area shall be removed to prevent potential impacts due to nesting activities." Please identify which trees could potentially be removed and discuss if those identified trees are protected by local ordinances and/or have potential suitable habitat to support the federally threatened California gnatcatcher (Polioptila californica californica) and other migratory and raptor bird species. 2. As part of the Section 106 compliance under the CWSRF Program, Native American consultation is required. Please include documentation of ali contact made with the tribes affiliated with the Project area.

Our review of the proposed Project is based upon: the information provided in the MND, including Biological Resources Report (LSA Associates 2012) and the Environmental Impact Assessment (EIA); our knowledge of sensitive and declining vegetation communities in the County of San Diego; and our participation in regional conservation planning efforts and the City's Habitat Management Plan (HMP). The primary concem and mandate of the Service is the protection of public fish and wildlife resources and their habitats. The Service has legal responsibility for the welfare of migratory birds, anadromous fish, and endangered animals and plants occurring in the United States. The Service is also responsible for administering the Endangered Species Act of 1973 (Act), as amended (16 U.S.C. 1531 et seq.) including habitat conservation plans (HCPs) developed under section 10(a) (1) of the Act, such as the City's HMP. The Department is a Tmstee Agency and a Responsible Agency pursuant to the Califomia Environmental Quality Act (CEQA), Sections 15386 and 15381, respectively. The Department is responsible for the conservation, protection, and management of the state's biological resources, including rare, threatened, and endangered plant and animal species, pursuant to the Califomia Endangered Species Act (CESA), and administers the Natural Community Conservation Planning Program (NCCP). The City is currently participating in the NCCP and the Service's HCP programs by implementing its HMP. The project site is located between Vancouver Street and Via de Canto Road, off Carlsbad Village Drive in the City of Carlsbad, San Diego County, Califomia. Topography ofthe project area includes flat land, moderate slopes, and steep slopes in City-owned property. The \^ w Ms. Pam Drew (FWS/CDFG-SD-12B0273-12TA0480) 2 surrounding area consists of undeveloped open space to the north and south, and residential development to the west and east. The area is further surrounded by undeveloped open space east of Vancouver Street. Portions of the project are in the Hardline Preserve Area (HPA) established by the City's HMP. The proposed project involves the installation of 1,543 linear feet of 8- and 10-inch gravity sewer pipeline located within the public right-of-way of Vancouver Street, Hidden Canyon Community Park, and a private street. The proposed project would also abandon, in place, 1,845 linear feet of 8-inch sewer pipeline. Existing above grade appurtenances associated with the existing sewer lift station would be demolished and the area hydro-seeded with a native seed mix. The 8-inch polyvinyl chlorine sewer pipe would be installed via open trench within the public right-of-way of Vancouver Street and within the Community Park (600 linear feet). The 10-inch high density polyethylene sewer pipe (943 linear feet) proposed within the HPA would be installed via horizontal directional drilling (HDD). HDD is a trenchless technique, and would connect with an existing sewer pipeline on Via de Canto Street. Approximately 0.102 acre of coastal sage scmb and 0.002 acre of non-wetland waters of the U.S. are present within the study area. However, project activities do not involve above-ground disturbance or grading; thus, the project will avoid any direct temporary or permanent impacts to natural vegetation. Riparian, aquatic or wetland vegetation is not present on the project site. Mitigation measures to reduce potential impacts to biological resources include temporary orange constmction fencing between the project footprint and the adjacent open space, biological monitoring of constmction activities, nesting bird avoidance/minimization, and coastal California gnatcatcher (Polioptila californica californica) avoidance/minimization. The draft MND also addresses noise and erosion control, the HMP Hardline Preserve adjacency standards applicable to this project. Noise-generating equipment will be avoided during the breeding season and noise levels inside the preserve will not exceed 60 dBA Leq and all work will be conducted in accordance with the City's National Pollutant Discharge Elimination System (NPDES) permit requirements, including BMPs, which will limit erosion and siltation on and offsite. Therefore, the proposed project is consistent with the City's HMP. Because of its proximity to various waterways, the Wildlife Agencies only concem about the Project is the potential for escape of the bentonite slurry used for the HDD of the pipeline . Present within the project area are concrete V ditches that drain directly to the Pacific Ocean (EIA, page 18), specifically Agua Hedionda Lagoon. While the HDD method generally creates fewer impacts than traditional trenching, the use of a clay lubricant, specifically bentonite slurry, can have permanent and lasting impacts on aquatic species and their habitats when hydrofractures (commonly referred to as, "frac-outs") occur. Bentonite is often considered non- toxic; however, benthic invertebrates, aquatic plants, fish, and their eggs can be smothered by fine particles of bentonite if it is discharged into waterways. While mitigation measure BIO-2 partially addresses our concems, the Wildlife Agencies recommend a separate mitigation measure that requires the contractor to develop and submit a Ms. Pam Drew (FWS/CDFG-SD-12B0273-12TA0480) 3 drilling mud control plan as described in the project's constmction plans (page 2, HDD Notes) that focuses on the minimization of direct, indirect, and cumulative impacts that may occur from hydrofractures associated with directional drilling. The drilling mud control plan at a minimum should include the following: 1. Techniques to reduce potential for hydrofracture and inadvertent retums that could pollute Agua Hedionda Lagoon: a. Sufficient earth cover should be used to increase resistance to hydrofracture. b. An adequately dense drilling fluid should be used to avoid travel of drilling fluid in porous sands. c. The bore should be conducted in a manner that avoids collapse. d. Borehole pressure should be maintained at levels low enough to avoid hydrofracture. e. Reaming and pullback rates should be maintained at rates slow enough to avoid over- pressurization of the bore. f. The surface above the vicinity of the drill head should be visually monitored for surface evidence of hydrofracture. g. Drilling methods should be modified to suit site conditions such that hydrofracture does not occur. 2. Hydrofractures should be cleaned immediately after they occur. Necessary response equipment should be readily accessible and in good working order. 3. All field persoimel should understand their responsibility for timely reporting of hydrofractures. The Wildlife Agencies appreciate the opportunity to comment on the draft MND for this project and to assist the City in further minimizing and mitigating project impacts to biological resources to ensure consistency with its HMP.

In addition to the area where the old tower is being removed, this should include all areas where there is ground disturbance where it is not already bare dirt. This should include equipment storage areas and possibly others. Several invasive plant species are shown as being present on the project site. Ground disturbance makes it easier for these species to spread. Reseeding will help reduce such potential indirect impacts from ground disturbance associated with the project. - hydroseed plant mix Plant mix to be used for hydroseeding was not specified. In addition to assuring that no plants on the CA-IPC list are used this also needs to specify: plants on the SD Museum of Natural History list of plants of local concern are also avoided, seeds will be locally sourced from San Diego county to reduce genetic contamination. - potential pipe "welding" impacts -We found no discussion of potential air quality impacts from the on site "welding" ofthe pvc pipe. Such materials can emit toxic fumes under some circumstances. Please explain how such potential fumes are being addressed. - no GHG impacts discussion We realize that this type of project will be producing a relatively small amount of GHG ( 2,150 Ibs/day). The air quality analysis provided the computation for volume produced and included this statement " Emissions of C02 are included for global climate change discussion." But no such discussion was included in the MND. Please add discussion about global climate change impacts and analysis as to whether 2,150 Ibs/day is significant. - monitoring wildlife movement Mitigation measure BIO-2 included that the on-site biological monitor will include evaluation of any impacts to wildlife movement. This issue is often overlooked in CEQA documents. We thank you for recognizing the importance of including this and hope that this becomes routine language for all projects where there is a need for an onsite biologist. Please reply to confirm timely receipt of these comments. We look forward to working with you to address these few concerns with this project.

The Rincon Band has concems for impacts, disturbances, and destmction to historic properties, cultural resources, and findings of significant value that are considered culturally important to the Luiserio people. This is to inform you that the identified project location is within the Aboriginal Territory of the Luiseno people, and also within Rincon's historic boundaries. The Cultural Resources Survey Results prepared by LSA in November 2011 reveals a close proximity of the project to a known archaeological site, CA-SDI-8913. All cultural resources located within our Traditional Use Area are of concem to Rincon, and we are also concemed for the protection of inadvertent archaeological discoveries that could be made at the project site. The Cultural Resources Survey Results states, "The presefecd of shell indicates that there is a potential for buried archaeological deposits possibly associated with CA-SDI-8913" (p. 1). We agree with the enviroimiental mitigation measures CUL-1 and CUL-2 regarding archaeological monitoring and Native American monitoring for any and all ground disturbance activities. Additionally, we request that you would provide us with updates regarding the project. If you have any questions, please contact (760) 297-2635.

California. Dear Ms. Drew: The Native American Heritage Commission (NAHC), the State of California 'Trustee Agency' for the protection and preservation of Native American cultural resources pursuant to Califomia Public Resources Code §21070 and affirmed by the Third Appellate Court in the case of EPIC v. Johnson (1985:170 Cal App. 3"^ 604). This letter includes state and federal statutes relating to Native American historic properties of religious and cultural significance to American Indian tribes and interested Native American individuals as 'consulting parties' under both state and federal law. State law also addresses the freedom of Native American Religious Expression in Public Resources Code §5097.9. The California Environmental Quality Act (CEQA - CA Public Resources Code 21000-21177, amendments effective 3/18/2010) requires that any project that causes a substantial adverse change in the significance of an historical resource, that includes archaeological resources, is a 'significant effect' requiring the preparation of an Environmental Impact Report (EIR) per the CEQA Guidelines defines a significant impact on the environment as 'a substantial, or potentially substantial, adverse change in any of physical conditions within an area affected by the proposed project, including ...objects of historic or aesthetic significance." In order to comply with this provision, the lead agency is required to assess whether the project will have an adverse impact on these resources within the 'area of potential effect (APE), and if so, to mitigate that effect. The NAHC did conduct a Sacred Lands File (SLF) search within the 'area of potential effect (APE} and Native American cultural resources were not identified in the project area specified; however, it is in close proximity to recorded cultural resources. The NAHC "Sacred Sites,' as defined by the Native American Heritage Commission and the California Legislature in California Public Resources Code §§5097.94(a) and 5097.96. Items in the NAHC Sacred Lands Inventory are confidential and exempt from the Public Records Act pursuant to California Government Code §6254 (r). Early consultation with Native American tribes in your area is the best way to avoid unanticipated discoveries of cultural resources or burial sites once a project is undenway. Culturally affiliated tribes and individuals may have knowledge of the religious and cultural significance of the historic properties in the project area (e.g. APE). We strongly urge that you make contact with the list of Native American Contacts on the attached list of Native American contacts, to see if your proposed project might impact Native American cultural resources and to obtain their recommendations concerning the proposed project. Pursuant to CA Public Resources Code § 5097.95, the NAHC requests cooperation from other public agencies in order that the Native American consulting parties be provided pertinent project information. Consultation with Native American communities is also a matter of environmental justice as defined by California Govemment Code §65040.12(e). Pursuant to CA Public Resources Code §5097.95, the NAHC requests that pertinent project information be provided consulting tribal parties. The NAHC recommends avoidance as defined by CEQA Guidelines §15370(a) to pursuing a project that would damage or destroy Native American cultural resources and Section 2183.2 that requires documentation, data recovery of cultural resources. Furthermore, the NAHC if the proposed project is under the jurisdiction of the statutes and regulations ofthe National Environmental Policy Act (e.g. NEPA; 42 U.S.C. 4321-43351). Consultation with tribes and interested Native American consulting parties, on the NAHC list, should be conducted in compliance with the requirements of federal NEPA and Section 106 and 4(f) of federal NHPA (16 U.S.C. 470 ef seq), 36 CFR Part 800.3 (f) (2) & .5, the President's Council on Environmental Quality (CSQ, 42 U.S.C 4371 etseq. and NAGPRA (25 U.S.C. 3001- 3013) as appropriate. The 1992 Secretary of the Interiors Standards for the Treatment of Historic Properties were revised so that they could be applied to all historic resource types included in the National Register of Historic Places and including cultural landscapes. Also, federal Executive Orders Nos. 11593 (preservation of cultural environment), 13175 (coordination & consultation) and 13007 (Sacred Sites) are helpful, supportive guides for Section 106 consultation. The aforementioned Secretary ofthe Interior's Standards include recommendations for all 'lead agencies' to consider the historic context of proposed projects and to "research" the cultural landscape that might include the 'area of potential effect.' Confidentiality of "historic properties of religious and cultural significance" should also be considered as protected by Califomia Govemment Code §6254( r) and may also be protected under Section 304 of he NHPA or at the Secretary of the Interior discretion if not eligible for listing on the National Register of Historic Places. The Secretary may also be advised by the federal Indian Religious Freedom Act (cf. 42 U.S.C, 1996) in issuing a decision on whether or not to disclose items of religious and/or cultural significance identified in or near the APEs and possibility threatened by proposed project activity. Furthermore, Public Resources Code Section 5097.98, California Government Code §27491 and Health & Safety Code Section 7050.5 provide for provisions for inadvertent discovery of human remains mandate the processes to be followed in the event of a discovery of human remains in a project location other than a 'dedicated cemetery'. To be effective, consultation on specific projects must be the result of an ongoing relationship between Native American tribes and lead agencies^ project proponents and their contractors, in the opinion of the NAHC. Regarding tribal consultation, a relationship built around regular meetings and infonnal involvement with local tribes will lead to more qualitative consultation tribal input on specific projects. Finally, when Native American cultural sites and/or Native American burial sites are prevalent within the project site, the NAHC recommends 'avoidance' of the site as referenced by CEQA Guidelines Section 15370(a). If you have anv^uestions about this response to your request, please do not hesitate to /6ontict me at (9y6) §^76251. /Sincerely, WeS^ Program Ane tl Cc: State clearinghouse Attachment: Native American Contact List CJ Native American Contacts San Diego cCltv July 9, 2012 Pala Band of Mission Indians Tribal Historic Preservation Office/Shasta Gaugher 35008 PalaTemecula Road, PMB Luiseno 50 .

The 8-inch pelyvinyl chlorine (PVC) sewer pipe will be installed via open trench within the public right-of-way of Vancouver Street and within the Community Park (600 linear feet). The 10-inch high density polyethylene (HDPE) sewer pipe, proposed within a Hardline Preserve area, will be installed via horizontal directional drilling (HDD), a trenchless technique (943 linear feet) and will con- nect with an existing sewer pipeline on Via de Canto Street. PROPOSED DETERMINATION: The Gity of Carisbad has conducted an en- vironmental review of the above described project pursuant to the Guidelines for Implementation of the Caiifomia Environmental Quality Act (CEQA) and the Environmental Protection Ordinance of the City of Carlsbad. As a result of said review, the initiai study (EIA Part 2) identified potentially significant effects on the environment, but (1) revisions in the project plans or proposals made by, or agreed to by, the appiicant before the proposed negative declaration and initial study are released for public review would avoid the effects or mitigate the effects to a point where cleariy no significant effect on the environment would occur, and (2) there is no substantial evidence in light of the whole record be- fore the City that the project "as revised" may have a significant effect on the environment. Therefore, a Mitigated Negative Declaration will be recom- mended for adoption by the City of Carisbad City Planner. A copy of the initial study (EIA Part 2) documenting reasons to support the proposed Mitigated Negative Declaration is on file in the Planning Division, 1635 Faraday Avenue, Carlsbad, California 92008. Comments from the public are invited. Pursuant to Section 15204 of the CEQA Guidelines, in reviewing Mitigated Negative Deciarations, persons and public agencies should focus on the proposed finding that the project will not have a significant effect on the environment. If persons and public agencies believe that the project may have a significant effect, they should: (1) identify the specific effect; (2) explain why they believe the effect would occur; and (3) explain why they believe the effect would be significant. Please submit comments in writing to the Planning Divi- sion within 30 days of the date of this notice. The proposed project and Mitigated Negative Declaration are subject to review and approval/adoption by the City Planner.

OTHER PUBLIC AGENCIES WHOSE APPROVAL IS REQUIRED (i.e., permits, financing approval or participation agreements): No other approvals are anticipated 9. PROJECT DESCRIPTION: The purpose of the project is to extend an existing sewer line from a segment of Vancouver Street to Via de Canto Street. The new sewer extension would be gravity fed and would eliminate the need for the existing sewer lift station. The gravity system will provide a more reliable system of conveying wastewater, reducing spill risks and eliminating energy consumption required for operating the pumps at the existing lift station. The proposed project involves: 1) installing 1,543-linear feet of 8- and 10-inch gravity sewer pipeline (located within the public right-way of Vancouver Street, Hidden Canyon Community Park and a private street); 2) abandoning in place 1,845-linear feet of 8-inch sewer pipeline; 3) demolishing the above grade appurtenances associated with the existing sewer lift station; and 4) hydro-seeding all disturbed areas within the preserve using seeds locally sourced from San Diego County and that no exotic invasive species, which are defined by the Califomia Invasive Plant Council (CA-IPC), as those with moderate to high risk, or other non-native species shown to be locally invasive. The only other area that will be disturbed is the grass area within the park, which will be reseeded with grass seed. The proposed gravity sewer line will allow the removal of an existing sewer lift station, located within a hardline Preserve area, as shovm on the city's Habitat Management Plan (HMP), dated November 2004. EL\ 11-02 VANCOUVER STREET HDD SEWER EXTENSION The 8-inch polyvinyl chlorine (PVC) sewer pipe will be installed via open trench within the public right-of-way of Vancouver Street and within the Community Park (600 linear feet). The 10-inch high density polyethylene (HDPE) sewer pipe, proposed within a Hardline Preserve area, will be installed via horizontal directional drilling (HDD), a trenchless technique (943 linear feet) and will connect with an existing sewer pipeline on Via de Canto Street. The HDD technique utilizes drilling mud (slurry, bentonite), which will be contained and controlled pursuant to a city-approved Drilling Mud Control Plan. Staging areas for equipment will be located within the public right-of- way on Vancouver Street. An Equipment Staging and Traffic Control Plan will be submitted to the city for review and approval and a Street Encroachment Permit from the city will be issued prior to commencement of ground disturbance. Segments of pipe will be laid out for on-site assembly (see Figure 3, Project Footprint) on existing paved surfaces along Vancouver Street and in the parking area for Hidden Canyon Community Park. A drill pit and exit pit will be excavated using typical pipeline excavation methods and equipment. Pit location options (for both the drill pit and the exit pit) are situated outside of sensitive habitats on the private roadway on Via de Canto Street and in omamental vegetation east of the park (as showTi in Figure 3).The proposed HDD technique will avoid impacts to sensitive habitat types and areas potentially subject to water resource agency jurisdiction (i.e., U.S. Army Corps of Engineers, Regional Water Quality Control Board, and Califomia Department of Fish and Game jurisdictional areas) on the ground surface. The installation of sewer pipe through the Hardline Preserve area will occur approximately 8 to 65 feet below the ground surface in order to avoid impacts to surface resources. Constmction will be conducted for approximately 2-3 months and is anticipated to conunence in September 2012 and be completed by January 2013 (outside the bird breeding season). Phases for HDD (3 weeks), open cut/trench installation of manholes and pipelines (4 weeks), and demolition of the existing lift station and restoration of affected existing surface improvements (2 weeks) will overlap. Aboveground appurtenances associated with the existing lift station will be removed after demolition. The belowground component ofthe existing lift station will be abandoned and the vault will be filled and capped. Areas of pavement affected by the drill pit excavation or open cuts will be restored to pre-project conditions. Permanent impacts will result firom the constmction of six 5- foot diameter manholes to access the proposed sewer line. The manholes will be constmcted in paved areas within Vancouver Street and Via de Canto Street and within the park. Although installation of the pipeline is considered permanent, no permanent aboveground impacts will occur as a result of pipeline constmction. 10. ENVIRONMENTAL SETTING: The project occurs within identified Hardline Preserve areas, public right-of-way, a private driveway and through the city's Hidden Canyon Community Park (as shown in Figure 2, HMP Location Map. 11. SURROUNDING LAND USES: Surrounding land uses include open space preserves, a community park, and single-family and multi-family residences.

LH I find that the proposed project MAY have "potentially significant impact(s)" on the environment, but at least one potentially significant impact 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. A Negative Declaration is required, but it must analyze only the effects that remain to be addressed. LH I find that although the proposed project could have a significant effect on the envirorunent, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier ENVIRONMENTAL IMPACT REPORT or NEGATIVE DECLARATION pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier ENVIRONMENTAL IMPACT REPORT or NEGATFVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project. Therefore, nothing further is required. Z:y^^ 1r-7-/^ Date City Plarmer's Signature Date EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION ENVIRONMENTAL IMPACTS STATE CEQA GUIDELESIES, Chapter 3, Article 5, Section 15063 requires that the City conduct an Environmental Impact Assessment (EIA) to determine if a project may have a significant effect on the envirormient. The Environmental Impact Assessment appears in the following pages in the form of a checklist. This checklist identifies any physical, biological, and human factors that might be affected by the proposed project and provides the City with information to use as the basis for deciding whether to prepare an Environmental Impact Report (EIR), Negative Declaration, or to rely on a previously approved EIR or Negative Declaration. • A brief explanation is required for all answers except "No Impact" answers that are adequately supported by an information source cited in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved. A "No Impact" answer should be explained when there is no source document to refer to, or it is based on project-specific factors as well as general standards. • "Less Than Significant Impact" applies where there is supporting evidence that the potential impact is not significantly adverse, and the impact does not exceed adopted general standards and policies. • "Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Than Significant Impact." The developer must agree to the mitigation, and the City must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level. • "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significantly adverse. • Based on an "EIA-Initial Study," if a proposed project could have a potentially significant adverse effect on the envirormient, but aU potentially significant adverse effects (a) have been analyzed adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigated Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed project, and none of the circumstances requiring a supplement to or supplemental EIR are present and all the mitigation measures required by the prior environmental document have been incorporated into this project, then no additional environmental document is required. t When "Potentially Significant Impact" is checked, the project is not necessarily required to prepare an EIR if the significant adverse effect has been analyzed adequately in an earlier EIR pursuant to applicable standards and the effect will be mitigated, or a "Statement of Overriding Considerations" has been made pursuant to that earlier EIR. • A Negative Declaration may be prepared if the City perceives no substantial evidence that the project or any of its aspects may cause a significant adverse effect on the environment. • If there are one or more potentially significant adverse effects, the City may avoid preparing an EIR if there are mitigation measures to clearly reduce adverse impacts to less than significant, and those mitigation measures are agreed to by the developer prior to public review. In this case, the appropriate "Potentially Significant Impact Unless Mitigation Incorporated" may be checked and a Mitigated Negative Declaration may be prepared. • An EIR must be prepared if "Potentially Significant Impact" is checked, and including but not limited to the following circumstances: (1) the potentially significant adverse effect has not been discussed or mitigated in an earlier EIR pursuant to applicable standards, and the developer does not agree to mitigation measures that reduce the adverse impact to less than significant; (2) a "Statement Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION of Overriding Considerations" for the significant adverse impact has not been made pursuant to an earlier EIR; (3) proposed mitigation measures do not reduce the adverse impact to less than significant; or (4) through the EIA-Initial Study analysis, it is not possible to detemiine the level of significance for a potentially adverse effect or detennine the effectiveness of a mitigation measure in reducing a potentially significant effect to below a level of significance. A discussion of potential impacts and the proposed mitigation measures appears after each related set of questions. Particular attention should be given to discussing mitigation for impacts, which would otherwise be detemiined significant. Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION AESTHETICS - Would the project: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources, including but not limited to, trees, rock outcroppings, and historic buildings within a State scenic highway? c) Substantially degrade the existing visual character or quality of the site and its surroundings? d) Create a new source of substantial light and glare, which would adversely affect daytime or nighttime views in the area? Potentially Significant Impact • • • • Potentially Significant Unless Mitigation Incorporated • • • • Less Than Significant No Impact Impact • • • • a) Have a substantial adverse effect on a scenic vista? No Impact. The project includes the removal of an existing sewer lift station and the constmction of an underground gravity flow sewer pipeline segment, which will allow for the removal of the above ground sewer lift station. No above ground stmctures are proposed. There will be minor and short term temporary impacts during constmction, which would include trenching equipment, staging areas, and HDD drill equipment. However, the removal of the existing above ground sewer lift station will improve the aesthetics of the area located within a residential area and open space preserves. Therefore, the project would not a) adversely affect a scenic vista; b) substantially damage scenic resources, c) degrade the existing visual character of any site, or d) create a new source of substantial light and glare, which would adversely affect day or nighttime views in the area. As a result, no impact will occur in regard to aesthetics. b) Substantially damage scenic resources including but not limited to trees, rock outcroppings, and historic buildings within a state scenic highway? No Impact. No unique scenic resources are present on site or in the vicinity of the site. Although some vegetation will be removed during maintenance, there are no city-designated heritage trees or otherwise locally important trees on the site that would be affected by project activities. No rock outcroppings will be affected by the proposed project. No historic buildings are located in or adjacent to the project site. The existing sewer lift station (shown in Figure 4, Site Photos) will be demolished and aboveground components will be removed during constmction, but this will improve the visual character of the area. The areas affected by constmction (i.e., trenching and drill pit excavation) will be restored to pre-project conditions during the last phase of constmction. The area of proposed impact is not located within the viewshed of a State scenic highway or any State highway that is designated by the Califomia Department of Transportation (Caltrans) as eligible for listing as a scenic highway. As a result, no impact will occur to scenic resources. 10 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION c) Substantially degrade the existing visual character or quality of the site and its surroundings? No Impact. The project area is located in an area designated by the General Plan as open space, with a small portion of the project occurring in medium density and single family residential. The existing visual character of the site consists of an open space area with native vegetation surrounded by apartment complexes, roadways, and a community park with omamental landscaping. The proposed constmction activities will be short-term and temporary, and will occur for a period of 2-3 months. Changes to the visual environment during the constmction of the project include the presence of constmction vehicles, tmcks, and typical earthmoving equipment (e.g., backhoes, excavators, and drilling equipment). Permanent visual improvements of the proposed project will occur as a result of demolition and removal of the existing sewer lift station on Vancouver Street. As a result, no impact will occur on the existing visual character or quality of the site and surrounding areas. d) Create a new source of substantial light and glare, which would adversely affect daytime or nighttime views in the area? No Impact. The proposed constmction activities will be performed during daylight hours only. No lighting or aboveground reflective surfaces are proposed. The proposed project would not create a new source of light or glare and would not significantly affect nighttime views in the area. As a result, no impact will occur to nighttime views and glare. 11 Rev. 07/06/11 Concrete V ditch adjacent to Via de Canto facing southeast. Existing lift station looking north.

AGRICULTURAL AND FOREST RESOURCES - (In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the Califomia Agricultural Land Evaluation and Site Assessment Model-1997 prepared by the Califomia Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In detennining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the Califomia Department of Forestry and Fire Protection regarding the state's inventoiy of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment Project; and forest carbon measurement methodology provided in Forest Protocols adopted by the Califomia Air Resources Board.) Would the project: a) Convert Prime Farmland, Unique LH LH LH K Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the Califomia Resources Agency, to non-agricultural use? b) Conflict with existing zoning for LD LH LH IS agricultural use or a Williamson Act contract? c) Conflict with existing zoning for, or cause LH LH LH S rezoning of forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Govemment Code Section 51104(g))? d) Result in the loss of forest land or LH LH LH 13 conversion of forest land to non-forest use? e) Involve other changes in the existing LH LH LH K environment, which, due to their location or nature, could result in conversion of Farmland to non-agricultural use or conversion of forest land to non-forest use? a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency to nonagricultural use? No Impact. The project site is not cunently used for farming and is not designated for agricultural use in the General Plan. The project site is partially located in an area designated as "Farmland of Local 13 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION Importance" by the Califomia Department of Conservation - San Diego Coimty Important Farmland (September 2002). This category is defined as "land of importance to the local economy, as defined by each county's local advisory committee and adopted by its Board of Supervisors. Farmland of Local Importance is either cunently producing, or has the capability of production, but does not meet the criteria of Prime Farmland, Farmland of Statewide Importance, or Unique Farmland." In San Diego, Farmland of Local Importance is land that meets all the characteristics of Prime and Statewide, with the exception of irrigation and is of significant economic importance to the County. Areas designated as Farmland of Local Importance conespond to the open space areas in the project site. This area is not cunently being utilized for agricultural production, and is not zoned for agricultural use by the city. Furthermore, surface impacts to this open space area are being avoided through the use of horizontal directional drilling (HDD) techniques and the project will not result in a temporary or permanent change to the existing uses of the site. Therefore, the project would not convert farmland to non-agricultural use. As a result, no impact will occur to Farmland. b) Conflict with existing zoning for agricultural use or a Williamson Act contract? No Impact. The majority of the proposed project site is currently zoned for open space uses (a small portion occurs within lands zoned for residential). Although agricultural operations are allowed in the open space zone, no agricultural operations are presently conducted in the proposed project area. The project area is not located on Williamson Act land, nor does a Williamson Act Contract restrict development on the site. The site is not zoned for agricultural use nor will the project affect land use on the site. As a result, no impact will occur related to zoning for agricultural uses or Williamson Act contract. c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code secfion 4526), or timberland zoned Timberland Production (as defined by Government Code Section 51104(g))? No Impact. The project would not conflict with the existing zoning or land uses within the project alignment or in adjacent areas. The project is not proposed wdthin a forestry or timber zone, nor is any part of the project area used for forestry or timber purposes. As a result, no impacts will occur related to the rezoning of forest land, timberland, or timberland production. d) Result in the loss of forest land or conversion of forest land to non-forest use? No Impact. The project is not located within or in the vicinity of a Federal, State, or locally designated forest and will not result in the loss of forest land or the conversion of any forest lands to a non-forest use either directly or indirectly. As a result, no impacts will occur related to conversion of forest lands. e) Involve other changes in the existing environment, which, due to their location or nature, could result in conversion of Farmland to non-agricultural use or conversion of forest land to non- forest use? No Impact. The project will not result in the conversion of any agricultural or forest lands either directly or indirectly. As a result, no impact will occur related to conversion of farmland or forest land. 14 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION Potentially Significant Potentially Unless Less Than Significant Mitigation Significant No Impact Incorporated Impact Impact III. AIR QUALITY - (Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations.) Would the project: a) Conflict with or obstmct implementation LH LD LH ^ of the applicable air quality plan? b) Violate any air quality standard or LH LH ^ LH contribute substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net LH LH ^ LH increase of any criteria pollutant for which the project region is in non-attainment under an applicable Federal or State ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial LH LH K LH pollutant concentrations? e) Create objectionable odors affecting a LH LH ^ LH substantial number of people? a) Conflict with or obstruct implementation of the applicable air quality plan? No Impact. The proposed project is located within the San Diego Air Basin, which is under the jurisdiction of the San Diego County Air Pollution Control District (SDAPCD). The climate of the San Diego Air Basin is dominated by the strength and position of the semi-permanent high-pressure system over the Pacific Ocean, known as the Pacific High. Sinking or subsiding air fi-om the Pacific High creates a temperature inversion, known as a subsidence inversion, which acts as a lid to vertical dispersion of pollutants. This inversion layer acts as a trap for sunshine and emissions that then react together to form ozone. The San Diego Air Basin is designated as non-attainment for the State ozone, particulate matter less than 10 microns in size (PMio), and particulate matter less than 2.5 microns in size (PM2.5) standards. The SDCAPCD has developed a Regional Air Quality Strategy (RAQS) to attain the State air quality standards for ozone. At present, no attainment plan for PM2.5 or PMio is required by the State regulations according to the County Guidelines for Determining Significance for Air Quality (2007). According to these Guidelines, projects that propose development that is consistent with the grovi^h anticipated by the general plans would be consistent with the RAQS. The proposed project would not expand capacity or extend service compared to existing conditions, and therefore would not contribute to growth of housing or population, increase fijture emissions, or result in other growth beyond the estimates that were used to develop the RAQS. As a result, the proposed project is consistent with the RAQS. As a result, the 15 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION proposed project would not conflict with or obstmct implementation of applicable air quality plans and no impacts relative to air quality attainment plans would occur as a result of the proposed project. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Less Than Significant Impact. As stated above, the San Diego Air Basin is designated as non-attainment for the State ozone, PMio, and PM2.5 standards. Long-term operation of the proposed project would not result in additional air pollutant emissions compared to existing conditions; therefore, long-term operational emissions would not violate any relevant Federal, State, or regional air quality standards for the San Diego Air Basin. However, as discussed below, constmcfion of the proposed project would result in short-term and temporary emissions of criteria air pollutants. Constmction activities would generate combustion emissions fi-om generator engines, on-site heavy-duty constmction vehicles and equipment, equipment hauling materials to and from the site, and motor vehicles transporting constmction crews. Exhaust emissions during constmction would vary daily as constmction activity levels change. The use of constmction equipment would result in localized exhaust emissions. Based on the proposed schedule, the peak-day emissions associated with constmction have been estimated using the CalEEMod model. The modeled constmction emissions are summarized in Table A. Emissions worksheets are included in Appendix A. As indicated in Table A below, constmction equipment emissions would not exceed the daily thresholds for the criteria pollutants CO, ROC, NOx, SO2, PMio, and PM2.5. It is assumed that there will be overlap of the demolition and HDD constmction phases. Emissions of CO2 are included for the global climate change discussion. All work will be conducted in compliance with Califomia Air Resources Board (CARB) mles and regulations for reduction of fiigitive emissions.

As a result, the proposed project would not contribute substantially to an existing or projected violation and impacts would be less than significant. c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable Federal or State ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? 16 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION Less Than Significant Impact. As discussed previously, the region in which the project is proposed is designated by State air quality standards as nonattainment for ozone, PMIQ, and PM2,5. Short-term constmction of the proposed project would not contribute substantially to significant air quality violations. Constmction equipment would be temporary and limited to portable engines and vehicles that are compliant with State emissions standards and are not expected to result in a cumulatively considerable net increase of nonattainment criteria pollutants in the project region. Given the limited emissions associated with the constmction phase of the project, local and regional air quality would be essentially the same whether or not the proposed project is implemented. As a result, the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant and impacts will be less than significant. d) Expose sensitive receptors to substantial pollutant concentrations? Less Than Significant Impact. Sensitive receptors such as residences, schools, parks, and churches located within the project site and vicinity may be subject to temporary impacts associated with project constmction. Project constmction activities are not anticipated to result in the exposure of sensitive receptors to substantial pollutant concentrations because emissions from project constmction activities would be minor, localized, and short-term, and would not generate substanfial pollutant concentrations. Once the project is constmcted, the gravity sewer line would not generate any air quality emissions. As a result, future project operation would not generate or expose sensitive receptors to a significant amount of pollutant emissions and impacts would be less than significant. e) Create objectionable odors affecting a substantial number of people? Less Than Significant Impact. Constmction activities may generate some site-specific odors associated with vehicle, equipment exhaust, and refueling of vehicles and equipment. Because these emissions would be localized, short-term, intermittent, and temporary, they would not adversely affect a substantial number of people in the vicinity of the proposed project. In addition, there would be limited use of gas or diesel-powered generators during constmction. As a result, impacts related to objectionable odors would be less than significant. 17 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION IV.

Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION Potentially Significant Unless Mitigation Incorporated. The project study area is located on flat land to moderate and steep slopes on city-owned property. The sunoimding area consists of undeveloped open space to the north and south, and residential development to the west and east. The area is further sunounded by undeveloped open space east of Vancouver Street. Portions of the project are contained within the Hardline Preserve according to the city's HMP, dated November 2004. Surveys were conducted by LSA in May 2011 and no special-status wildlife species were observed on site during project surveys, per the Biological Resources Technical Report (BTR) prepared by LSA, dated May 2011 and updated in Febmary 2012 (Appendix B). Special-status wildlife species with a high potential to occur on site due to the presence of suitable habitat within the Hardline Preserve areas include coastal Califomia gnatcatcher {Polioptila califomica califomica). This species relies on coastal sage scmb habitat, and approximately 0.102 acre of coastal sage scmb is present within the project study area. However, the project will avoid any direct impact to the natural vegetation communities, including coastal sage scmb. Permanent Impacts will occur only within areas mapped as "developed." As stated above, permanent impacts will result from the constmction of six 5-foot diameter manholes to access the proposed sewer line and the demolition of the sewer lift station located along Vancouver Street. The manholes will be constmcted in paved areas within Vancouver Street (2) and Via de Canto Street (1) and within the parking lot and omamental vegetation of the park (3). Although installation of the pipeline is considered permanent, no permanent aboveground impacts will occur as a result of pipeline constmction. No permanent impacts will occur in vegetated areas. Temporary impacts that may result from implementation of the proposed project include: 1) the storage of materials and equipment within the proposed pipeline laydown areas; 2) the establishment of a boring pit and an exit pit for HDD; 3) disturbance of vegetation adjacent to the entry and exit pits due to worker and equipment access; and 4) noise and dust disturbance to birds and other wildlife utilizing habitat in and adjacent to the project impact area. These disturbances will occur during constmction activities for a limited duration. Fugitive dust generated during constmction will be reduced as a result of compliance with applicable CARB mles and regulations and implementation of best management practices (BMPs). Therefore, no adverse effects on biological resources due to fiigitive dust are anticipated. Impacts associated with noise generation are minimal and temporary in nature. However, disturbance during constmction may temporarily cause indirect impacts to the adjacent open space areas and habitat that could support coastal Califomia gnatcatcher. The following avoidance, minimization and mitigation measures would reduce impacts to coastal Califomia gnatcatcher, as well as other birds protected by the Migratory Bird Treaty Act (MBTA), to a level of insignificance. BIO-1 In order to avoid impacts to adjacent open space habitats during constmction, all impacted open space interfaces will require temporary orange constmction fencing which clearly delineates the edge of the approved limits of grading and clearing and environmentally sensitive areas beyond. This fencing shall be installed in all areas adjacent to protected open spaces, and shall be installed prior to constmction, and maintained for the duration of constmction activity. Fencing shall be installed in a manner that does not impact habitats to be avoided. The applicant shall submit to the City for approval, at least seven days prior to initiating project impacts, the final plans and photographs for initial clearing and gmbbing of habitat and project constmction. These final plans shall include photographs that show the fenced limits of impact and all areas to be impacted or avoided. If work occurs beyond the fenced or demarcated limits of impact, all work shall cease until the problem has been remedied and mitigation identified, to the satisfaction of the biological monitor. Temporary orange constmction fencing shall be removed upon project completion of constmction of the project. 19 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION BIO-2 The developer shall hire a biological monitor to monitor the constmction operations. The biological monitor shall have the ability to halt constmction work, if necessary and confer with the city and Wildlife Agencies to ensure the proper implementation of species and habitat protection measures. The biologist shall report any violation to the USFWS within 24 hours of its occunence. The biological monitor shall be present to monitor clearing, grading, and constmction activities in the vicinity of biological open space areas. The biological monitor shall have the authority to stop constmction and require additional precautions or conservation measures to protect the proposed open space preserve areas, including the wildlife movement corridor, as necessary. Implementation of this measure shall be verified by the city prior to and concunent with constmction. BIO-3 Prior to the commencement of any ground-disturbing activities (i.e., drilling, trenching, grading) that occur between January 15 and September 15, a biological survey by a qualified biologist shall be conducted of the project area. If active raptor and/or migratory bird nests are observed during the constmction phase, a buffer area of adequate width (typically 500 feet), as determined by the monitoring biologist, shall be established between the constmction activities and the nest so that nesting activities are not intermpted. To avoid potential impacts, trees shall be removed outside of the breeding season of local raptor species (trees shall be removed between September 15 and January 15). Noise attenuation and buffer (if required) shall remain in place until the constmction activities are completed or the nest is no longer active. Implementation of this measure shall be verified by the city. BIO-4 Constmction noise created during the breeding season that could affect the breeding of the Califomia gnatcatcher, migratory songbirds and other bird species associated with the adjacent coastal sage scmb habitat shall be avoided. This restriction can be waived by the city, with concunence from the Wildlife Agencies, upon completion of a breeding/nesting bird survey of the area in accordance with the Migratory Bird Treaty Act (MBTA). A biological monitor of the constmction operation is required. If nests are present, no loud constmction (exceeding 60 dBA hourly average, adjusted for ambient noise levels, at the nesting site) may take place within 500 feet of active nesting sites during the nesting/breeding season (January 15 through September 15). b) Have a substantial adverse effect on any riparian, aquatic or wetland habitat or other sensitive natural community identified in local or regional plans, policies, or regulations or by California Department of Fish and Game or U.S. Fish and Wildlife Service? Potentially Significant Unless Mitigation Incorporated. Riparian, aquatic or wetland habitat is not present on the project site. Coastal sage scmb, which is identified as a sensitive habitat type in the city's HMP, occurs in the open space preserves within, and adjacent to, the project area. No permanent or temporary impact to sensitive habitat, including CDFG jurisdictional areas and coastal sage scmb, is proposed as part of the project activities. Coastal sage scmb occurs adjacent to the drill pit excavation area on Via de Canto Street. Adjacency standards for projects adjacent to Hardline Preserve areas are discussed in the city's HMP and generally address issues of fire management, erosion control, landscaping, fencing, signage, indirect impacts, and non-native species control. The adjacency standards applicable to this project include noise and erosion control. Due to the proximity of the project to various waterways, and the potential for escape of bentonite slurry from using the HDD method, the constmction notes on the project plans will state that the contractor shall submit and implement a "frac-out" plan" to minimize the potential for release of fiiel or lubricants, and will clean up bentonite slurry in the event of an accidental release. Mitigation Measure BIO-5 will ensure that the project is conducted. 20 . Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION Noise-generating equipment should be avoided during the breeding season and noise levels inside the preserve should not exceed 60 dBA Leq. Mitigation Measure BIO-1 will ensure that the project is consistent with this adjacency standard. All work will be conducted in accordance with the city's National Pollutant Discharge Elimination System (NPDES) permit requirements, including BMPs, which will limit erosion and siltation on site and off site and will ensure consistency with the erosion adjacency standard. Compliance with applicable regulations and implementation of Mitigation Measures BIO-1 and BIO- 5 will ensure that project impacts are less than significant. BIO-5 In order to avoid impacts to various waterways during constmction, the constmction notes on the project plans shall state that the contractor shall submit and implement a "frac-out" plan. The plan at a minimum shall include the following: 1. Techniques to reduce potential for hydrofracture and inadvertent retums that could pollute Agua Hedionda Lagoon: a) Sufficient earth cover should be used to increase resistance to hydrofracture. b) An adequately dense drilling fluid should be used to avoid travel of drilling fluid in the porous sands. c) The bore should be conducted in a manner that avoids collapse. d) Borehole pressure should be maintained at levels low enough to avoid hydrofracture. e) Reaming and pullback rates should be maintained at rates slow enough to avoid over pressurization of the bore. f) The surface above the vicinity of the drill head should be visually monitored for surface evidence of hydrofracture. g) Drilling methods should be modified to suite site conditions such that hydrofracture does not occur. 2. Hydrofractures should be cleaned immediately after they occur. Necessary response equipment should be readily accessible and in good working order. 3. All field persoimel should understand their responsibility for timely reporting of hydrofractures. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? No Impact. The two concrete-lined v-ditches located within the study area, which convey flows during storm events (ephemeral) and as a result of nuisance mnoff, are tributary to the Pacific Ocean (a Traditional Navigable Water [TNW] of the U.S.). Because of the direct connection of storm drain systems with the Pacific Ocean these features are subject to U.S. Army Corps of Engineers (Corps) jurisdiction to the ordinary high water mark (OHWM) under Section 404 of the Federal Clean Water Act (CWA). The channels of these features show evidence of an OHWM by the presence of watermarks. Within the project study area, LSA mapped 0.002 acre of non-wetland waters of the U.S. No wetland waters of the U.S. were observed within the study area. The project activities do not involve ground disturbance or grading. No activities regulated under Section 404 ofthe CWA (i.e., dredge, filling, hydrological intermption, etc.) are proposed as part of this project. As a result, no impacts would occur to federally protected wetlands. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? 21 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION No Impact. The vegetation within the project study area is mostly contiguous within the areas designated as Hard Line, is designated as open space, and is not subject to continuous disturbance. The project study area is in the vicinity of Core 2, as defined by the city's HMP, and wildlife species likely use the site as a movement corridor. There is potential for temporary impacts to wildlife movement during constmction; however, the short duration of constmction and limited surface disturbance is not expected to result in substantial impedances to wildlife movement. Upon completion of constmction, the site will provide the same wildlife movement function as the existing situation. The project will not result in impacts to wildlife movement beyond the existing conditions on site. Based on the nature of the proposed impacts, and the avoidance of impacts to open space areas, the proposed project will neither limit wildlife movement nor contribute substantially to fragmentation of habitat As a result, no impact will occur to the movement of native resident or migratory fish or wildlife species. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? No Impact. The city does not have an adopted tree preservation policy or ordinance and the proposed project would not affect any other biological resources protected by policies or ordinances beyond those discussed above under Responses IV. a) through IV. d). As a result, no impact will occur in regard to a conflict with tree preservation or other local policies or ordinances. f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Flan, or other approved local, regional, or state habitat conservation plan? Less Than Significant Impact. The approved city HMP for Natural Communities in the City of Carlsbad (2004) identifies the subject site as a "Proposed Hardline Conservation Area." Since the time of HMP adoption, the site has been included as part of the Hardline Conservation Area. The HMP designates a natural preserve system and provides a regulatory framework for determining impacts and assigning mitigation. No other local, regional or state habitat conservation plans specific to this site encumber the property. In addition, the improvements proposed are consistent with the open space and habitat preserve uses outlined in the HMP. The project will not change the allowed open space uses on the site or adversely affect the preserve management in this area. The proposed project is consistent with the city's HMP. It also does not conflict with the zoning or General Plan land uses allowed on the site. As a result, impacts related to conservation plans would be less than significant. 22 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION Potentially Significant Potentially Unless Less Than Significant Mitigation Significant No Impact Incorporated Impact Impact CULTURAL RESOURCES - Would the project: a) Cause a substantial adverse change in the LH LH Ll Kl significance of a historical resource as defined in §15064.5? b) Cause a substantial adverse change in the LH S LH LH significance of an archaeological resource pursuantto §15064.5? c) Directly or indirectly destroy a unique LH K LH LH paleontological resource or site or unique geologic feature? d) Disturb any human remains, including those LH LH LH 13 intened outside of formal cemeteries? a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5? No Impact. LSA conducted an archaeological field survey of the project alignment on November 2, 2011. The pedestrian survey covered the entire project alignment. The archaeological survey was conducted pursuant to the CEQA and the City of Carlsbad's implementing regulations and guidelines. The archaeological survey was conducted to determine if any cultural resources eligible for inclusion in the Califomia Register of Historical Resources (Califomia Register) or significant under the city guidelines will be affected by this project. The report has been prepared according to State Historic Preservation Office (SHPO) guidelines for Archaeological Resource Management Reports (ARMR). No historical resources were located within the project alignment. As a result, no impact will occur to historical resources. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? Potentially Significant Unless Mitigation Incorporated. As stated above, LSA conducted an archaeological field survey ofthe project alignment on November 2, 2011. During the survey, a small disturbed shell scatter was observed on the northeast portion of the project alignment within 25 feet ofthe previously recorded site. The presence of shell indicates that there is a potential for buried archaeological deposits possibly associated with the previously recorded site within this area of the project alignment. Therefore, archaeological monitoring is recommended during demolition of the existing lift station and during any ground-disturbing activities. Sediments within the rest of the project area appear to have been the result of cut and fill operations and did not contain any cultural resources, as indicated by the Geotechnical Evaluation report prepared by Ninyo & Moore, dated August 27, 2010. The report indicated that fill material is present to a depth of approximately 8 feet. The remaining project area is highly disturbed as a result of development and 23 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION therefore has a limited probability of containing buried cultural resources. Based on the disturbed landform context and field survey observations, no monitoring or further work related to cultural resources is recommended for these areas. The following mitigation measures will ensure that impacts to archaeological resources are less than significant. CUL-1 - Prior to the commencement of groimd-disturbing activities, the project developer shall retain a qualified archaeologist to monitor groimd-disturbing activities. The qualified archaeologist shall be on-site during all grading, trenching, and other ground-disturbing activities unless otherwise agreed upon by the archaeologist and city staff. In the event any potential cultural resource is uncovered during the course of the project constmction, ground-disturbing activities in the vicinity of the fmd shall be redirected until the nature and extent of the find can be evaluated by the archaeological monitor. If cultural resources are encountered, the archaeologist shall have the authority to temporarily halt or redirect grading/trenching while the cultural resources are documented and assessed. If archaeological resources are encountered during excavation or grading, the archaeological monitor shall direct the contractor to avoid all work in the immediate area for a reasonable period of time to allow the archaeologist to evaluate the significance of the finding and determine an appropriate course of action. The appropriate course of action may include, but not be limited to avoidance, recordation, relocation, excavation, documentation, curation, data recovery, or other appropriate measures. The Project Contractor shall provide a reasonable period of time for pursuing the appropriate activities, including salvage of discovered resources. Salvage operation requirements pursuant to Section 15064.5 of the CEQA Guidelines shall be followed. Recovered artifactual materials and data shall be cataloged and analyzed. A report shall be completed describing the methods and results of the monitoring and data recovery program. Artifacts shall be curated with accompanying catalog to cunent professional repository standards or the collection will be repatriated to the appropriate Native American Tribe(s), as specified in the pre-excavation agreement. If any human remains are discovered, all constmction activity in the immediate area of the discovery shall cease immediately, and the Archaeological monitor shall notify the County Medical Examiner pursuant to Califomia Health and Safety Section 7050.5. Should the Medical Examiner detemiine the human remains to be Native American, the Native American Heritage Commission shall be contacted pursuant to Califomia Public R.esources Code Section 5097.98. The Native American Monitor (pursuant to Mitigation Measure CUL-2), in consultation with the Native American Heritage Commission, shall inspect the site of the discovery of the Native American remains and may recommend to the City of Carlsbad, and the project contractor, actions for treating or disposing, with appropriate dignity, the human remains and any associated grave goods. The recommendation may include the scientific removal and nondestmctive analysis of human remains and items associated with Native American burials. The project contractor shall provide a reasonable period of time for salvage of discovered human remains before resuming constmction activities. CUL-2 - Prior to the commencement of ground disturbing activities, the project developer shall retain the services of a Native American monitor. The purpose of this monitoring will be to allow for tribal observation of trenching excavation including formalized procedures for the treatment of Native American human remains and burial, ceremonial, or cultural items that may be uncovered during any ground disturbance activities. Prior to implementation of the monitoring, a pre-excavation agreement shall be developed between the appropriate Native American Tribe and the City of Carlsbad. The Native American representative(s) shall attend the pre-grading meeting with the contractors to explain the requirements of the program. The Native American monitor shall be on-site during all grading, trenching, and other ground- disturbing activities unless otherwise agreed upon by the monitor and city staff c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? 24 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION Potentially Significant Unless Mitigation Incorporated. The subject site is located in an area geologically characterized by largely decomposed granite, granitic rock, and Santiago formation sedimentary rock. The geotechnical investigation of the project prepared by Ninyo & Moore, dated August 2010, contains information that the project is underlain by artificial fill and the Santiago Formation. Based on the description of the boring logs that extended to a depth of 61 feet below grade, the Santiago Formation will be encountered beneath the artificial fill beginning at 1 to 8 feet below grade. The geotechnical report stated that artificial fill materials were composed of clayey to silty sand that was various shades of brown, moist and loose to medium dense. The geotechnical report also stated that the Santiago Formation consisted of gray to brown, weakly to strongly cemented silty sandstone with interbeds of moderately to strongly cemented siltstone. Some portions of the Santiago Formation were so well cemented that the drilling rig could not penetrate them. A search of paleontological records housed in the Department of Paleontology at the San Diego Natural History Museum (SDNHM) was conducted on November 1, 2011, and is documented in the Paleontological Assessment prepared by LSA. The results indicate that there are 13 known paleontological localities located within a l-mile radius of the project; however, none are located within the project area. Four of these localities occur within uimamed Pleistocene (approximately 200,000 years old) alluvial and estuarine deposits. Recovered fossils include trace remains of marine invertebrates (e.g., crabs, snails, clams, and pectens), marine vertebrates (e.g., sharks), and tenestrial vertebrates (e.g., turkeys, horses, bison, deer, and camels). Nine localities were found in the middle Eocene (approximately 43 to 42 million years ago) Santiago Formation, Member C in fluvial, lagoonal, and marine deposits. These nine localities produced impressions of seeds (e.g., flowering plants), trace remains of marine invertebrates (e.g., bunow infillings), shell remains and impressions of marine invertebrates (e.g., foraminifera, snails, clams, oysters, ostracods, and crabs), mineralized remains of marine vertebrates (e.g., sharks, fish), and mineralized bone of tenestrial vertebrates (e.g., amphibians, soft-shelled turtles, tortoises, crocodiles, lizards, and marsupials, insectivores, bats, rodents, carnivores, primates, tapirs, rhino relatives, and oreodonts). The closest known locality within the Santiago Formation is located approximately 0.6 mile away. The SDNHM states that the Santiago Formation has a knovm high paleontological sensitivity in the County. In addition, because ofthe known fossil occunences in the immediate project area, the SDNHM recommends that any proposed excavation activities that extend deep enough to encounter previously undisturbed deposits of the Santiago Formation have the potential to cause impacts to paleontological resources preserved in these deposits, and that a paleontological resource mitigation program be developed for ground-disturbing activities associated with this project. A survey of the project area was conducted on November 2, 2011, by LSA Cultural Resources Manager, Elizabeth Davidson. Most of the project area where ground disturbance is proposed is developed and contains asphalt paving and omamental landscaping. What sediment was visible within the surface of the project area appeared to be artificial fill, which is consistent with the geotechnical report. However, some of the native sediments that outcrop on adjacent hillsides near the southem portion of the project at Via De Canto Street were consistent with the Santiago Formation, as they have been mapped. No paleontological resources were observed during this survey. Based on the known occunence of significant paleontological resources within the Santiago Formation, it is assigned a High paleontological potential and sensitivity rating. As such, paleontological mitigation will be required on this project to mitigate impacts to paleontological resources. Based on the geotechnical report (Ninyo & Moore 2010), most portions of the project contain artificial fill, which does not have paleontological sensitivity or potential; however, in most cases excavation will extend deep enough to contact the underlying Santiago Fonnation. 25 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION The portions of the project that will be installed using HDD techniques will not require paleontological mitigation, as the sediments that are removed are usually not directly visible because the sediments are ground up during the drilling process and pumped into a holding tank. Mitigation will be required during excavation of the entry and exit pits associated with the HDD, as these pits do allow the direct observation of excavated sediments, and excavation depths will likely extend beneath the fill that was noted by Ninyo & Moore (2010). Excavation associated with the portion of the sewer line that will be installed via an open trench (see Figure 3) will also require paleontological mitigation, as the proposed excavation depths will likely extend deeper than the 5 to 8 feet of fill noted by Ninyo & Moore (2010) in this area and contact the underlying Santiago Formation. The following mitigation measure will ensure that impacts to paleontological resources are less than significant. CUL-3 - Prior to any excavation or trenching into undisturbed, older Pleistocene sediment, the project developer shall retain a qualified paleontologist during constmction excavations within these sediment deposits, if any, to observe constmction excavations. Furthermore, the Paleontologist shall develop a Paleontological Resources Impact Mitigation Monitoring Plan (PRIMMP). The PRIMMP should include, but not be limited to; attendance at the pre-grade meeting by a qualified paleontologist; monitoring of excavation activities; spot-screening of sediments for small (or micro-) vertebrates; identification and curation of specimens; and preparation of a report of findings. In the event that any unique paleontological resources are encotmtered, the resources shall be salvaged, recorded, and curated, imder the direction of the monitoring paleontologist. d) Disturb any human remains, including those interred outside of formal cemeteries? No Impact. A review of cultural literature of the vicinity ofthe alignment of the project concludes that no known human remains are located in the area of impact of the proposed project. The Califomia Health and Safety Code (Section 7050.5) states that if human remains are discovered on the project site, no further disturbance shall occur until the County Medical Examiner has made a determination of origin and disposition pursuant to Public Resources Code Section 5097.98. As adherence to state regulations, and mitigation measure CUL-1, would be required, no additional mitigation would be necessary in the unlikely event that human remains were discovered during constmction of the project. As a result, no impact to human remains will occur. 26 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION VI.

The project area is situated in the westem portion of the Peninsular Ranges geomorphic province of Southem Califomia. This geomorphic province encompasses an area that extends 125 miles from the Transverse Ranges and the Los Angeles Basin, south to the Mexican border, and beyond another 775 miles to the southem tip of Baja Califomia. The westemmost portion of the province in San Diego County, where the site is located, generally consists of Upper Cretaceous, Tertiary, and Quatemary age sedimentary rocks. The most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the north San Diego County area, indicates that the project is considered to be in a seismically active area, as is most of Southem Califomia. This map however, indicates that the subject site is not underlain by known active faults, nor is there evidence of ground displacement in the area during the last 11,000 years. The Rose Canyon fault zone is the closest known fault, which is the onshore portion of an extensive fault zone that includes the Offshore Zone of Deformation and the Newport-Inglewood fault to the north of the subject site. The Elsinore fault zone is located approximately 22 miles east of the site, and the Coronado Bank fault is located approximately 25 miles west of the site. The potential for mpture resulting from earthquake is considered to be low. The Rose Canyon fault zone, located approximately six miles westerly of the subject site, is made of predominantly right-lateral strike-slip faults that extend south- southeast through the San Diego metropolitan area. The zone extends offshore at La Jolla, and continues north-northwest generally parallel to the coastline. Portions of the Rose Canyon fault zone in the San Diego area have been recognized by the State Geologist to be considered active. Additionally, the Julian and Temecula segments of the Elsinore fault zone, about 23 miles to the northeast of the subject site are also referenced in the Division of Mines and Geology Special Publication 42. The project site is not within a fault-mpture hazard zone or within a State of Califomia Earthquake Fault Zone (formerly known as an Alquist-Priolo Special Studies Zone) as determined in the geotechnical report prepared for the project (Ninyo & Moore 2010). The project design incorporates the recommendations from the geotechnical report. As a result, the project would not expose people or stmctures to potential substantial adverse effects, and impacts will be less than significant. aii) Strong seismic ground shaking? Less Than Significant Impact. As stated in the response to Vl.ai) above, the project site is not located within a State of Califomia Earthquake Fault Zone (formerly known as an Alquist-Priolo Special Studies Zone) as detemiined in the geotechnical report prepared for the project (Ninyo & Moore 2010). However, the site is located in a seismically active area (as is the majority of Southem Califomia) and the potential for strong ground motion in the project area is considered significant. The most significant seismic event likely to affect the proposed facilities would be a maximum moment magnitude 6.9 earthquake along the Rose Canyon fault zone, in which the horizontal peak ground acceleration has a 10 percent probability of exceedance in 50 years of 0.27g (27% of the acceleration of gravity) and a 5 percent probability of exceedance in 50 years of 0.4g. The project site will likely be subject to ground shaking in response to either a local moderate or more distant large-magnitude earthquake. Seismic risk at the site is comparable to the risk for the San Diego area in general. The closest source to the site for ground motion, and the source that would produce the greatest ground acceleration at the site, is the Del Mar segment of the Rose Canyon/Newport-Inglewood fault zone, about 6 miles west of the project site, and potentially the Julian and Temecula segments of the Elsinore fault zone, about 22 miles to the northeast of the project site. The project will not change or interfere with existing earthquake design standards. Furthermore, the project has been designed in accordance with the requirements of applicable constmction standards and incorporates the geotechnical design and constmction considerations described 28 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION in the geotechnical report (Ninyo & Moore 2010). As a result, the project impacts relating to strong seismic ground shaking are considered to be less than significant. aiii) Seismic-related ground failure, including liquefaction? No Impact. Liquefaction of soils with minimal cohesion can be caused by strong vibratory motion due to earthquakes. Research indicates that loose granular soils and silts that are saturated by a relatively shallow groundwater table are most susceptible to liquefaction. The geotechnical report (Ninyo & Moore 2010) concludes that, based on the relatively dense nature of the underlying earth materials (artificial fill and Santiago Formation), and the absence of a shallow groundwater table, the potential for liquefaction and seismically induced settlement to occur at the site is not a design consideration. Furthermore, liquefaction is not historically known to have occuned in San Diego County and recorded seismic shaking levels within the County have not been sufficient to trigger liquefaction (County of San Diego 2007). Within the County, there may be a potential for liquefaction in areas with loose sandy soils combined with a shallow groundwater table, which typically are located in alluvial river valleys/basins and floodplains. Steep slopes or alluvial deposit soils in low-lying areas are susceptible to liquefaction during earthquakes or heavy rains. San Diego County tenain has both of these characteristics and lies within several active earthquake zones (County of San Diego 2004). The extent of risk areas within the County with a potential for liquefaction hazard was mapped in the Multi-Jurisdictional Hazard Mitigation Plan (MJHMP). The project alignment is located within an area mapped as "low liquefaction risk" in the MJHMP. This classification in characterized by areas with low shake potential. Relatively dense formational sandstone and granitic rock underlies the project site. There is very low, if any, potential for liquefaction or seismically induced settlement in the vicinity of the proposed maintenance activities as discussed in the geotechnical report. As a result, no impacts will occur with regard to seismic-related ground failure. aiv) I.randslides? No Impact. Landslides occur when masses of rock, earth, or debris move down a slope, including rock falls, deep failure of slopes, and shallow debris flows. Landslides can be caused by human activities such as grading as well as natural events such as earthquakes and heavy rainfall. Landslide hazard areas in the County are generally concentrated along canyons near the coastal areas with steep slopes. The project is not located on any knovra unstable geologic units mapped in the MJHMP and there would not be any major grading activities associated with proposed maintenance activities that would affect the geologic stability of the areas. No landslides have been identified as having the potential to damage or affect the proposed project facilities. The geotechnical report for the project (Ninyo & Moore 2010) indicates that although landslides and slope instability have been mapped to the west and northeast of the site, no landslides or indications of deep-seated landsliding have been noted underlying the project site. The project will not increase the likelihood of landslides. As a result, no impacts will occur with regard to landslides. b) Result in substantial soil erosion or the loss of topsoil? Less Than Significant Impact. During the proposed constmction activities, very minor disturbance of surface soils is anticipated within the temporary pipeline laydovra areas, removal of the existing lift station, trenching within the roadway, and excavation of the boring entry and exit pits. Project activities will implement BMPs for the control of erosion, such as straw bale or sandbag barriers, silt fences, slope roughening, and outlet protection in exposed areas. Very few locations ofthe project area have exposed soils. Because the city will implement BMPs, including erosion control protection over the limited areas in which bare soil will be temporarily exposed. As a result, impacts to soil erosion or loss of topsoil are considered to be less than significant. 29 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION c) Be located on a geologic unit or soU that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? Less Than Significant Impact. As stated previously the project is not located on any known unstable geologic units mapped in the MJHMP and there would not be any major grading activities associated with proposed maintenance activities that would affect the geologic stability of the areas. No landslides have been identified as having the potential to damage or affect the proposed project facilities. The geotechnical report for the project (Ninyo & Moore 2010) indicates that although landslides and slope instability have been mapped to the west and northeast of the site, no landslides or indications of deep- seated landsliding have been noted underlying the project site. As a result, no impact will occur from landslide, lateral spreading, subsidence, liquefaction, or collapse. d) Be located on expansive soils, as defined in Section 1802.3.2 of the California Building Code (2007), creating substantial risks to life or property? No Impact. The site of the proposed maintenance project is composed of artificial fill and Tertiary-aged Santiago formation sediments (Ninyo & Moore 2010). Santiago formation geology is best described as light-colored, poorly-bedded, poorly indurated, fine to medium grained sandstone sedimentary rock. It is concluded that expansive soils are not a geological hazard for the subject project. As a result, no impact will occur from expansive soils. e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? No Impact. The proposed project is a public infrastmcture improvement project for the municipal sewer system. The subject project does not propose and will not necessitate the use of septic tank, or altemative wastewater disposal systems. No restrooms or other wastewater facilities are proposed. As a result, no impacts will occur to wastewater disposal systems. 30 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION VII. GREENHOUSE GAS EMISSIONS project: Would the a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? b) Conflict with an applicable plan, policy or regulation adopted for the purposes of reducing the emissions of greenhouse gases? Potentially Significant Impact • • Potentially Significant Unless Mitigation Incorporated • • Less Than Significant No Impact Impact • • a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Less Than Significant Impact. The potential for the project to contribute to greenhouse gases (GHGs) and global climate change will be minimal because emissions are temporary and associated only with the constmction phase of the project. Appendix A includes a summary of GHG emissions data. Table A in response III. b) shows GHG emissions associated with different constmction phases. Project-related GHG emissions do not affect global warming as an individual project. Instead, the project's potential incremental contribution combined with the cumulative increase of all other sources of GHGs, which when taken together, result in global climate change impacts. The following discussion reviews project- related GHGs and the project's potential generation of these gases. Califomia Assembly Bill AB 32 requires statewide GHG emissions reductions to 1990 levels by 2020. Global climate change (GCC) GHG emissions are an emerging environmental concem being raised on statewide, national, and global levels. Regional, state, and federal agencies are developing strategies to control emissions that contribute to GCC. The Califomia Resources Agency (CRA) adopted CEQA Guidelines that address GHG emissions on December 30, 2009. While these new guidelines do not include GHG significance thresholds, they do say that environmental documents must analyze the incremental contribution of a project to GHG levels and determine whether those emissions are cumulatively considerable. In order to detemiine whether or not a proposed project would cause a significant effect on the environment, the impact of the project must be determined by examining the types and levels of GHG emissions generated. GHG emissions related to utility relocation would be mainly from carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4) contained in exhaust from off-road diesel constmction equipment/vehicles (e.g., idling and operation of backhoes, cranes, and drilling rigs), from on-road tmcks used by vendors (to deliver materials to the site) and on-site workers, and from use of portable equipment (e.g., generators). It is anticipated that temporary GHG emissions may occur during the demolition of the existing sewer lift station and constmction of the gravity sewer line. These activities would be short-term and would not contribute to regional GHG emissions or climate change impacts. The short-term GHG emissions—CO2 equivalent (over the approximately 3 month project period)—were estimated at 305 metric tons using the CalEEMod model in conjunction with estimated vehicle/equipment usage schedules (Appendix A). 31 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION The GHG emissions from the proposed project are well below significance thresholds (e.g., 10,000 metric tons/year for constmction included in the South Coast Air Quality Management District suggested guidelines, December 2008; 7,000 metric tons/year by the CARB, October 2008). As a result, the project's contribution to overall GHG emissions and GCC impacts would be less than significant. b) Conflict with an applicable plan, policy or regulation adopted for the purposes of reducing the emissions of greenhouse gases? Less Than Sigmficant Impact. GHG emissions are not cunentiy regulated in the SDCAPCD. The GHG emissions from the sewer project are well below significance thresholds adopted by other agencies, as described in response VII. a) above. AB 32 requires statewide GHG emissions reductions to 1990 levels by 2020. Though these statewide reductions are now mandated by law, permanent GHG emission thresholds have not been established. On December 2, 2007, the CARB approved a Regulation for the Mandatory Reporting of Greenhouse Gas Emissions, which came into effect in January 2009. This reporting mle was one of the CARB's responsibilities under AB 32. The mle specifies that cement plants, oil refineries, hydrogen plants, electric-generating facilities, cogeneration facilities, electric retail providers, and other facilities emitting more than 25,000 metric tons per year of GHGs must submit aimual reports to the CARB. On September 22, 2009, the Administrator of the United States Environmental Protection Agency (USEPA) signed the Final Rule (Rule) for the Mandatory Reporting of Greenhouse Gas. The Rule was published in the Federal Register on October 30, 2009, and went into effect on December 29, 2009. The Rule requires that suppliers of fossil fiaels or industrial greenhouse gases, manufacturers of vehicles and engines, and facilities that emit more than 25,000 metric tons or more per year of GHG emissions submit annual reports to the USEPA. No permanent GHG emissions limitations are in effect, and the project does not exceed any reporting or significance thresholds. As a result, the project will not conflict with an applicable plan, policy or regulation adopted for the purpose of reducing emissions of greenhouse gases and impacts would be less than significant. 32 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION VIII. HAZARDS AND HAZARDOUS MATERIALS - Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? b) Create a significant hazard to the public or environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Govemment Code Section 65962.5 and, as a result, would it create a significant hazard to the public or environment? e) For a project within an airport land use plan, or where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Potentially Significant Potentially Unless Significant Mitigation Impact Incorporated • • • • • • • • • Less Than Significant No Impact Impact • • • • • • • • • • • • 33 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION Potentially Significant Potentially Unless Less Than Significant Mitigation Significant No Impact Incorporated Impact Impact h) Expose people or stmctures to a significant LH LH LH K risk of loss, injury, or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Less Than Significant Impact. Constmction activities do not require use of substantial quantities of hazardous materials such as petroleum products, paint, oils, and solvents. All transport, handling, use, and disposal of small quantities of such materials, as may be associated with fiieling constmction and drilling equipment, will comply with all federal, state, and local laws regulating the management and use of hazardous materials. All materials associated with the demolition of the existing lift station will be removed from the site for proper disposal. Horizontal directional drilling entails the use of bentonite slurry, which has the potential to be released into the environment in the event of a frac-out. Bentonite slurry is an inert substance and is not characterized as a hazardous material. The constmction contractor will implement appropriate BMPs to minimize the potential for release of fiiel or lubricants, and will clean up bentonite slurry in the event of an accidental release. As a result, the impact to the public or the environment through the routine transport, use, or disposal of hazardous materials is less than significant. b) Create a significant hazard to the public or environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Less Than Significant Impact. No significant hazard involving the release of hazardous material into the environment would be anticipated since only moderate quantities of hazardous materials (e.g., constmction equipment fueling and lubrication) will be utilized, and only during the constmction period. No extraordinary risk of accidental explosion or the release of hazardous substances is anticipated with constmction or operation of the proposed project. Horizontal directional drilling entails the use of bentonite slurry, which has the potential to be released into the environment in the event of a frac-out. Bentonite slurry is an inert substance and is not characterized as a hazardous material. The constmction contractor will implement appropriate BMPs to minimize the potential for release of fiael or lubricants, and will clean up bentonite slurry in the event of an accidental release. As a result, impacts created by the accidental release of hazardous materials will be less than significant. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Less than Significant Impact. The subject project is approximately 0.6 mile west of the nearest public elementary school, Hope Elementary, located on Tamarack Avenue. Therefore, the site is not within one- quarter mile of a proposed school. The project is not anticipated to produce any hazardous emissions or handle hazardous or acutely hazardous materials, substances, or wastes once operational. Hazardous products (such as diesel fuel) will be used on the proposed project only during the constmction period. No permanent storage or transport of hazardous materials will occur on the subject project. Limited hazardous materials utilized during the constmction period will not constitute a significant impact on health or operations of the public school. As a result, impacts to existing or proposed schools will be less than significant. 34 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or environment? No Impact. A review of federal and state standard and supplemental databases, including lists of hazardous materials sites compiled pursuant to Govemment Code Section 65962.5 for environmental concems, was compiled by Environmental FirstSearch, June 20, 2011. The subject site is not included on a list of hazardous materials sites (federal database) compiled pursuant to Government Code Section 56962.5. Several databases were searched for inclusion of the subject area and/or any sunounding areas pursuant to the requirements of American Society for Testing and Materials (ASTM) 1527-05 and Govemment Code Section 65962.5. The database search was conducted for the project site and up to a 1 mile radius of the site. The results of the database searches are included in the Environmental FirstSearch Report dated June 20, 2011 (Appendix E). The Environmental FirstSearch reports provide detailed records identified as well as listing the radius used in each database searched. One site was listed for the project area, but was not assigned a geographic location (i.e., non-geocoded). The listed information indicates the site is for Bureau of Indian Affairs (BIA) Contact Information and is not relevant to this project area because no BIA lands occur in the project vicinity. In addition, the site is not in the United States Environmental Protection Agency (USEPA) database of cunent and potential Superfund sites cunentiy or previously under investigation. Also, to the best of the USEPA's knowledge, it has been determined that no steps will be taken to list this site on the National Priorities List (NPL). It is not on any list of registered hazardous waste generators, or on a database of sites that treat, store, dispose of, or incinerate hazardous waste. The subject property is not included on any list of hazardous materials, and has no known previous use history that would involve the use or storage of hazardous materials. As a result, no impacts will occur to the public or environment. e) For a project within an airport land use plan, or where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or woridng in the project area? No Impact. The project area is located approximately 4 miles northwest of McClellan-Palomar Airport. The City of Carlsbad has an adopted airport land use plan (McCllellan-Palomar Airport Land Use Compatibility Plan, Amended March 4, 2010). Since the proposed project is located in excess of two miles from the closest airport and is not within the airport land use planning area, the site does not meet the minimum qualifications as having the potential for safety hazard for people residing or working in the project area. As a result, no impacts will occur to people residing or working in the project area. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? No Impact. The project is not within the vicinity of a private airstrip and no people will reside on the site. As a result, no impact will occur to people residing or working in the project area. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Less Than Significant Impact. The project activities will not permanently affect, block, or interfere with traffic on public streets, including any streets that would be used for an emergency response plan or emergency evacuation plan. During constmction, work will be required within the road on Vancouver Street and Via de Canto Street. A traffic control plan will be approved by the city prior to implementation of the project and will include measures that will ensure that emergency response is not impaired. Project 35 Rev. 07/06/11 EIA. 12-01 VANCOUVER STREET HDD SEWER EXTENSION operations are not proposed in any area that would physically interfere with an adopted emergency response plan or emergency evacuation plan. As a result, impacts related to emergency response plans are less than significant. h) Expose people or structures to a significant risk of loss, injury, or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? No Impact. The closest houses to the subject activity area are adjacent to the drilling site on Via de Canto Street. The proposed project is not residential and thus will not expose new residences to wildland fire risk. Project constmction does not involve the installation of use of electrical components or fire hazards. The project operations do not involve installation or use of electrical components and will not result in any significant additional exposure of neighboring residences to wildfire risk. The proposed project will not expose residences in the vicinity to significant wildland fire risk. As a result, no impact will occur involving risk of loss, injury, or death involving wildland fires. 36 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION IX. HYDROLOGY AND WATER QUALITY - Would the project: a) Violate any water quality standards or waste discharge requirements? b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (i.e., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? c) Substantially alter the existing drainage pattem of the site or area, including through the alteration of the course of a stream or river, in a manner, which would result in substantial erosion or siltation on site or off site? d) Substantially alter the existing drainage pattem of the site pr area, including through the alteration of the course of a stream or river, or substantially increase the flow rate or amount (volume) of surface mnoff in a manner, which would result in flooding on site or off site? e) Create or contribute mnoff water, which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted mnoff? f) Otherwise substantially degrade water quality? g) Place housing within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood delineation map? Potentially Significant Potentially Unless Significant Mitigation Impact Incorporated • • • • • • • • • Less Than Significant No Impact Impact • • • • • • • • • • • • 37 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION Potentially Significant Potentially Unless Less Than Significant Mitigation Significant No Impact Incorporated Impact Impact h) Place within 100-year flood hazard area LH L3 LH K stmctures, which would impede or redirect flood flows? i) Expose people or stmctures to a significant LH LH LH ^ risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? j) Expose people or stmctures to inundation by LH LH LH K seiche, tsunami, or mudflow? a) Violate any water quality standards or waste discharge requirements? Less Than Significant Impact. Proposed constmction activities are required by law to comply with all federal, state and local water quality regulations, including the Califomia Water Authority (CWA), California Administrative Code Title 23, and specific basin plan objectives identified in the Water Quality Control Plan for the San Diego Basin (Califomia Regional Water Quality Control Board San Diego Region, 1994, as amended). All work will be conducted in accordance with the City's NPDES permit requirements, including BMPs, which will limit erosion and siltation on site and off site. Provisions in the constmction contract require the implementation of a constmction Stormwater Pollution Prevention Program (SWPPP) addressing each of the constmction activities of the project. The SWPPP will require applications of appropriate erosion control, sediment control, tracking control, non-stormwater management and, waste management and materials pollution control BMPs. The contractor shall speciflcally list California Stormwater Quality Association (CASQA) BMPs and provide a map of their locations as part of the SWPPP. Compliance with applicable regulations and a project-specific SWPPP will ensure that the project will have less than significant impacts. b) Substantially deplete groundwater supplies or interfere substantially witb groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (i.e., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? Less Than Significant Impact. According to the geotechnical evaluation (Ninyo & Moore 2010) groundwater was not encountered during subsurface exploration. However, seepage was encountered in the geotechnical boring B-4 (see Appendix F) at a depth of approximately 7 feet. Additionally, existing utility trench lines may act as conduits for perched water conditions. Due to the site topography, nearby areas of landscaping, and the potential for presence of existing utility trench lines, zones of seepage should be anticipated. Fluctuations in the groundwater level and perched conditions may occur due to variations in ground surface topography, subsurface geologic conditions, stmcture, etc. Because of the potential for seepage, dewatering measures during excavation operations are recommended in the geotechnical evaluation and will be implemented as part of the project design. The considerations for constmction dewatering include anticipated drawdovra, piping of soils, volume of pumping, potential for settlement, and groundwater discharge. Disposal of groundwater will be performed in accordance with applicable guidelines of the Regional Water Quality Control Board (RWQCB) as part of implementation 38 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION of the project. Development of a constmction SWPPP will ensure that appropriate BMPs are identified and implemented. Compliance with required regulations ensures that impacts will be less than significant. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner, which would result in substantial erosion or siltation on site or off site? Less Than Significant Impact. The project avoids the concrete drainage v-ditches that occur on the project site. The horizontal directional drilling technique utilizes trenchless technology. Furthermore, no trenches, grading, or excavation is proposed in undeveloped portions of the site. Project constmction activities will not alter the existing drainage of the site. No grading or ground disturbance in undeveloped areas is proposed. The proposed project vwll not substantially alter the existing pattem of mnoff from and through the project site. Development of a constmction SWPPP will ensure that appropriate BMPs are identified and implemented. As a result, no significant impact to drainage flow will result from implementation ofthe project. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the flow rate or amount (volume) of surface runoff in a manner, which would result in flooding on site or off site? No Impact. As stated above in response DC. c), the proposed project will not substantially alter the existing pattem of mnoff from and through the project site. As a result, no impact will occur in regard to the existing drainage pattem. e) Create or contribute runoff water, which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? No Impact. Implementation of the project will not result in a change to the existing runoff The project does not propose new impervious surfaces or a change in the hydrologic conditions on site. Erosion and siltation would be controlled and minimized, as discussed in response DC. c), through the implementation of BMPs, to be documented in the constmction SWPPP. No additional pollution of surface waters will result from the project. As a resuh, no impact will occur in regard to water runoff f) Otherwise substantially degrade water quality? No Impact. As stated above, erosion and siltation would be controlled and minimized, through the implementation of BMPs, to be documented in the constmction SWPPP. The proposed project will not otherwise substantially degrade water quality. As a result, no impact will occur to water quality. g) Place housing within a lOO-year flood hazard area as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood delineation map? No Impact. The project is located in Flood Hazard Zone X (FEMA Flood Insurance Rate Map data accessed through SANGIS), which includes "... areas outside the 1-percent-annual-chance floodplain, and areas of I-percent-annual-chance sheet flow flooding where average depths are less than 1 foot, areas of 1 -percent-annual-chance stream flooding where the contributing drainage area is less than 1 square mile, or areas protected from the 1-percent-aimual-chance flood by levees." No housing is proposed as part of the project and no changes to the 100-year flood hazard area will result from implementation of the project. As a result, no impact will occur in regard to housing within a 100-year flood hazard area. h) Place within lOO-year flood hazard area structures, which would impede or redirect flood flows? 39 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION No Impact. The project is not located within the 100-year flood hazard area. No permanent aboveground stmctures will be placed within the 100-year flood hazard area as part of the project. As a result, no impact will occur in regard to impeding or redirecting flood flows. i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? No Impact. The proposed sewer extension project does not involve the installation of stmctures and will not expose people to risk from the failure of a levee or dam. There are no levees or dams in the vicinity of the project. As a result, no impact will occur in regard to flooding or the failure of a levee or dam. j) Expose people or structures to inundation by seiche, tsunami, or mudflow? No Impact. The proposed project is not located within a tsunami impact area and is not anticipated to be affected by mudflow. The proposed project would not increase the likelihood of seiche. As a result, no impact will occur in regard to a seiche, tsunami or mudflow. 40 Rev. 07/06/11 EL\ 12-01 VANCOUVER STREET HDD SEWER EXTENSION X. LAND USE AND PLANNING - Would the project: a) Physically divide an established community? b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? c) Conflict with any conservation plan or conservation plan? applicable habitat natural community Potentially Significant Impact • • • Potentially Significant Unless Mitigation Incorporated • • • Less TTian Significant No Impact Impact • • • a) Physically divide an established community? No Impact. The project would not physically separate any contiguous residential areas since the project area is a sewer extension project that will be installed underground within the public right-of-way and through an open space area. As a result, no impact will occur in regard to an established community. b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? No Impact. The City of Carlsbad's General Plan Land Use Map (updated January 2009) designates the subject site as Open Space (OS), with small portions overlapping Medium Density Residential (RM). The existing zoning (updated Febmary 2009) on the site is also primarily Open Space (OS) with a small portion of the project area overlapping Planned Community and Single-Family Residential. No specific plan covers the property. The site is not located within the Coastal Zone. The project proposes no change to any land use on the site. As a result, no impact will occur to land uses. c) Conflict with any applicable habitat conservation plan or natural community conservation plan? No Impact. The City of Carlsbad's Habitat Management Plan (HMP) for Natural Communities in the City of Carlsbad, dated December 1999, identifies the existing sewer lift station site as a Proposed Standards Area and the area where the proposed pipeline would be located as an Existiiig Hardline Conservation Area (Figure 2). This conservation area use is consistent with the open space uses identified in the city's General Plan and Zoning Ordinance. Impacts to native vegetation will be avoided as discussed in section FV, Biological Resources, and the project is consistent with the city's HMP. No other 41 Rev. 07/06/11 EIA. 12-01 VANCOUVER STREET HDD SEWER EXTENSION habitat conservation plans are applicable to the project site. As a resuh, no impact will occur in regard to habitat conservation or natural community conservation plans. 42 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION XI. MINERAL RESOURCES - Would the project: a) Result in the loss of availability of a known mineral resource that would be of fiiture value to the region and the residents of the state? b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan? Potentially Significant Impact • • Potentially Significant Unless Mitigation Incorporated • • Less Than Significant No Impact Impact • • a) Result in the loss of availability of a known mineral resource that would be of future value to the region and the residents of the state? No Impact. No significant excavation will result from implementation of the project. No known or expected mineral deposits of future value to the region and the residents of the state are located in the immediate vicinity of the subject project. Additionally, the project would affect an area that has already been subject to disturbance as a result of constmction of sunounding residential communities and roads. As a result, no impact will occur to mineral resources. b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan? No Impact. The site is not designated in the City of Carlsbad General Plan or the Zoning Ordinance as a locally important mineral resource recovery site. The property is not regulated by any specific plan or other regulatory land use plan. As a resuh, no impact will occur to the loss of minerals. 43 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION XII.

A project will normally have a significant effect on the environment related to noise if it will substantially increase the ambient noise levels for adjoining areas or conflict with the adopted environmental plans and goals of the community in which it is located. The applicable noise standards goveming the project site are the criteria in the city's Noise Element of the General Plan and its Noise Ordinance. Noise Element of the General Plan. The Noise Element of the General Plan identifies certain sound levels that are compatible with various land uses. The city specifies outdoor and indoor noise limits for residential uses, places of worship, educational facilities, hospitals, hotels/motels, and commercial and other land uses. The noise standard for exterior living areas is 60 dBA CNEL for residential uses. 65 dBA CNEL is the noise standard for residential units subject to noise from 44 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION McClellan-Palomar Airport. The indoor residential noise standard is 45 dBA CNEL, which is consistent with the standard in the California Noise Insulation Standard. Municipal Code. The City's Noise Control Ordinance Chapter 8.48 govems the time of day that constmction work can be conducted. The Noise Control Ordinance prohibits the erection, demolition, alteration, or repair of any building or stmcture or the grading or excavation of land in such a manner as to create disturbing, excessive or offensive noise during the following hours: 1) After sunset on any day, and before seven a.m., Monday through Friday, and before eight a.m. on Saturday. 2) All day on Sunday, New Year's Day, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving Day, and Christmas Day. Short-Term Construction Noise Impacts. Short-term noise impacts would be associated with the demolition of the existing sewer lift station and trenching and drilling during constmction ofthe proposed sewer pipeline. Constmction-related short-term noise levels would be higher than existing ambient noise levels in the project area at the present time, but would no longer occur once constmction ofthe project is completed. Two types of short-term noise impacts could occur during constmction of the proposed project. First, constmction crew commutes and the transport of constmction equipment and materials to the site for the proposed project would incrementally increase noise levels on access roads leading to the site. A relatively high single-event noise exposure potential will exist at a maximum level of 87 dBA L^ax with tmcks passing at a distance of 50 feet. However, the projected constmction traffic will be minimal when compared to the existing traffic volumes on Vancouver Street, Carlsbad Village Drive, and other affected roads and its associated noise level change will not be perceptible. Therefore, short-term constmction-related worker commutes and equipment transport noise impacts would not be substantial. The second type of short-term noise impact is related to noise generated during demolition, trenching, minor grading, and drilling on the project site. Constmction is performed in discrete steps, each of which has its own mix of equipment, and consequently its own noise characteristics. These various sequential phases would temporarily change the character of the noise generated on site. Therefore, the noise levels vary as constmction progresses. Despite the variety in the type and size of constmction equipment, similarities in the dominant noise sources and pattems of operation allow constmction-related noise ranges to be categorized by work phase. Table B lists maximum noise levels recommended for noise impact assessments for typical constmction equipment based on a distance of 50 feet between the equipment and a noise receptor. Typical maximum noise levels range up to 89 dBA at 50 feet during the noisiest constmction phases. The site preparation phase, which includes excavation, tends to generate the highest noise levels, because the noisiest constmction equipment is earthmoving equipment. Earthmoving equipment includes excavating machinery such as backfillers, bulldozers, and front loaders. Earthmoving and compacting equipment includes compactors, scrapers, and graders. Earthmoving equipment use is expected to be limited to excavation of the boring test pits and trenching within the existing roadway. Some minor use of earthmoving equipment may be required to restore the grade following demolition of the existing sewer lift station. Typical operating cycles for these types of constmction equipment may involve one or two minutes of full power operation followed by three or four minutes at lower power settings. Constmction of the proposed project is expected to require the use of grader, drill rigs, water tmcks, and pickup tmcks. This equipment would be used on the project site. Based on Table B, the maximum noise level generated by each grader on the proposed project site is assumed to be 86 dBA Lmax at 50 feet from 45 Rev. 07/06/11 ELA 12-01 VANCOUVER STREET HDD SEWER EXTENSION the earthmover. The maximum noise level generated by water and pickup tmcks is approximately 86 dBA Lmax at 50 feet from these vehicles. Each doubling of a sound source with equal strength increases the noise level by 3 dBA. Assuming that each piece of constmction equipment operates at some distance from the other equipment, the worst-case combined noise level during this phase of constmction would be 89 dBA Lmax at a distance of 50 feet from the active constmction area. The constmction activities for the proposed project would be located within 25 feet of the residences on Vancouver Street and Via de Canto. Maximum constmction noise levels at these residences from main constmction activities would be 95 dBA Lmax- Temporary constmction activity noise generated between 7:00 a.m. and sunset Monday through Friday and between 8:00 a.m. and sunset on Saturday is exempt from the Noise Control Ordinance standards. Once constmction has been completed, the proposed project would not be a source of long-term noise. As a result, if constmction is limited to the hours specified above, the impacts remain less than significant. Table B: Typical Maximum Construction Equipment Noise Levels (Lmax) Type of Equipment Range of Maximum Sound Levels Measured (dBA at 50 feet) Suggested Maximum Sound Levels for Analysis (dBA at 50 feet) Pile Drivers, 12,000 to 18,000 ft-lb/blow 81 to 96 93 Rock Drills 83 to 99 96 Jack hammers 75 to 85 82 Pneumatic Tools 78 to 88 85 Pumps 74 to 84 80 Dozers 77 to 90 85 Scrapers 83 to 91 87 Haul Trucks 83 to 94 88 Cranes 79 to 86 82 Portable Generators 71 to 87 80 Rollers 75 to 82 80 Tractors 77 to 82 80 Front-End Loaders 77 to 90 86 Hydraulic Backhoe 81 to 90 86 Hydraulic Excavators 81 to 90 86 Graders 79 to 89 86 Air Compressors 76 to 89 86 Tmcks 81 to 87 86 Source; Noise Control for Buildings and Manufacturing Plants, Bolt, Beranek & Newman 1987. b) Exposure of persons to or generation of excessive groundbome vibration or groundbome noise levels? Less Than Significant Impact. Constmction ofthe project would not result in substantial groundbome vibration or groundbome noise on properties adjacent to the project site. Furthermore, operation of the gravity flow sewer line would not generate substantial groundbome noise and vibration. As a result, groundbome noise and vibration impacts are considered less than significant. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? 46 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION No Impact. The sewer line will be underground and will not generate any perceptible noise. As a result, no impact would occur to the existing ambient noise levels. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant Impact. Although there would at times be high intermittent constmction noise levels in the project area during project constmction, constmction of the project would not significantly affect land uses adjacent to the project site. In addition, constmction at the project site would comply with the hourly limits specified by the city's Ordinance (Chapter 8.48). As a result, any potential ambient noise level impacts are considered less than significant. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? No Impact. The proposed project is located approximately four miles from McClellan-Palomar Airport and outside any noise impact areas. As a result, no impacts will occur related to excessive airport noise. f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? No Impact. The proposed project is not in the vicinity of any private airstrip. As a result, no impacts will occur related to excessive airport noise within the vicinity of a private airstrip. 47 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION XHI. POPULATION AND HOUSING project: Would the a) Induce substantial growth in an area either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastmcture)? b) Displace substantial numbers of existing housing, necessitating the constmction of replacement housing elsewhere? c) Displace substantial numbers of people, necessitating the constmction of replacement housing elsewhere? Potentially Significant Impact • • • Potentially Significant Unless Mitigation Incorporated • • • Less Than Significant No Impact Impact • • • a) Induce substantial growth in an area either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? No Impact. The proposed project involves the extension of a sewer line and the elimination of the existing sewer lift station. It does not involve the development of new homes or businesses. It would not increase the capacity of the existing sewer system, or remove a barrier to growth. Rather, the gravity system will provide a more reliable system of conveying wastewater, reducing spill risks and eliminating energy consumption required for operating the pumps at the existing lift sewer station. The project would have no discemible impact on grov^^h, either directly or indirectly. As a result, no impact will occur to induce substantial growth. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? No Impact. The proposed project will not displace any existing housing because project activities are limited to the roadways, community park area, and existing open space areas. As a result, no impact will occur to existing housing. c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? No Impact. As stated above, the proposed project will not displace any people because no activities that require displacement of people, residences, or other development are proposed with project implementation. As a result, no impact will occur to necessitate the constmction of housing replacement elsewhere. 48 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant No Impact Impact XIV. PUBLIC SERVICES a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered government facilities, a need for new or physically altered government facilities, the constmction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services: i) Fire protection? • • • ii) Police protection? • • • iii) Schools? • • • iv) Parks? • • • v) Other public facilities? • • • ai) Fire protection? No Impact. Project activities will not result in the need for increased fire protection. As a result, no impact will occur related to fire protection. aii) Police protection? No Impact. Project activities will not result in any need for increased police protection. As a result, no impact will occur related to police protection. aiii) Schools? No Impact. This project will not result in the need for additional schools, as no student generation would occur as a result of the project and no schools would be affected. As a result, no impact will occur to schools. aiv) Parks? Less Than Significant Impact. The proposed maintenance activities will not increase demand for parks serving the area. Portions of Hidden Canyon Community Park will be affected during project constmction. The constmction areas in the park will be off-limits to the public for the 2 to 3-month duration of constmction; however, the project is not anticipated to significantly adversely affect recreational uses or create the need for additional park facilities. As a result, any potential impacts to parks are considered less than significant 49 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION av) Other public facilities? No Impact. The project will not require the constmction of additional public facilities. As a result, the project will have no impact. 50 Rev. 07/06/11 ELA 12-01 VANCOUVER STREET HDD SEWER EXTENSION XV. RECREATION-Would the project: a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b) Include recreational facilities or require the constmction or expansion of recreational facilities, which might have an adverse physical effect on the environment? Potentially Significant Impact • • Potentially Significant Unless Mitigation Incorporated • • Less Than Significant Impact • No Impact • a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? Less Than Significant Impact. The project does not include a component that would increase demand for regional or neighborhood parks (such as a residential development). Project constmction activities will not increase the use of Hidden Canyon Community Park. The constmction areas that are within the community park will be off-limits to the public for the temporary duration of constmction; however, no change to the community park facility is proposed. As a result, the temporary dismption of public access to the park during constmction is considered a less than significant impact. b) Does the project include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? No Impact. The proposed project does not propose constmction or expansion of recreational facilities. As a result, no impact will occur. 51 Rev. 07/06/11 EIA. 12-01 VANCOUVER STREET HDD SEWER EXTENSION XVI. TRANSPORTATION/TRAFFIC - Would the project: a) Conflict with an applicable plan, ordinance or policy establishing measures of effectiveness for the performance of the circulation system, taking into account all modes of transportation including mass transit and non-motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit? b) Conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? c) Result in a change in air traffic pattems, including either an increase in traffic levels or a change in location that results in substantial safety risks? d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? e) Result in inadequate emergency access? f) Conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities?

The project operations component is not expected to generate additional daily trips. Project constmction activities will generate up to 10 Average Daily Trips (ADT). Constmction traffic will utilize Vancouver Street (public) and Via de Canto Street (private). Additional access would be from Carlsbad Village Drive (a Collector Street). According to the City's Growth Management Plan 2011 Traffic Monitoring Program Summary Report (Rick Engineering 2011), the existing mid-block traffic nearest the project site is mid-block count location 25 located on Carlsbad Village Drive in the segment between Victoria Avenue and Pontiac Drive. The mid-block peak hour level of service (LOS) at the nearest mid-block count location is LOS A with 5,967 ADT. The 2011 peak hour LOS at the nearest intersection count location (Intersection Count Location 4, El Camino Real and Carlsbad Village Drive) is LOS A (a.m. peak hour) and LOS A (p.m. peak hour). The design capacities of the roads affected by the proposed project are less than 2,000 ADT for Via de Canto Street and Vancouver Street and less than 20,000 ADT for Carlsbad Village Drive, according to the City's General Plan Circulation Element (2004).The project traffic related to constmction would represent less than 1 percent of the existing traffic volume and the design capacity for each road. The proposed project would not cause an increase in traffic that is substantial in relation to the existing traffic load and capacity of the street system. As a result, the temporary impact during constmction is considered a less than significant impact. b) Conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? No Impact. In 2009 the congestion management agency (SANDAG) employed an "opt out" option defined in Assembly Bill (AB) 2419. The congestion management program is no longer relevant to development in the City of Carlsbad. As a result, the project will not conflict with an applicable congestion management program. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that result in substantial safety risks? No Impact. The proposed project is an underground sewer extension project and would not result in a change to air traffic pattems. The project is consistent with the McClellan-Palomar Airport Land Use Compatibility Plan, as Amended March 4, 2010. As a result, the project will not change air traffic pattems or result in substantial safety risks and will have no impact. d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? No Impact. No improvements or modifications to any public or private roads are proposed. A traffic control plan will be prepared for constmction activities necessary in Vancouver Street and Via De Canto Street. The project will not change the geometry of public roads as all new piping will be underground. The proposed project is consistent with the city's General Plan and Zoning. As a result, no impact will occur. e) Result in inadequate emergency access? Less Than Significant Impact. The proposed project will have no impact on existing emergency access. A traffic control plan will be prepared for constmction activities necessary in Vancouver Street and Via De Canto Street. The traffic control plan includes measures to ensure adequate emergency access is provided at all times during the constmction period. As a result, impacts are considered less than significant. 53 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION f) Conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities? No Impact. The project will not conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities. No parking facilities or other areas are proposed that would benefit from the installation of bike racks. Project implementation would not conflict with any public transit programs or polices and, with implementation of a traffic control plan for constmction activities necessary in Vancouver Street and Via De Canto Street, would not decrease the performance of such facilities. As a result, no impact will occur. 54 Rev. 07/06/11 ELA 12-01 VANCOUVER STREET HDD SEWER EXTENSION XVII. UTILITIES AND SERVICE SYSTEMS - Would the project: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? b) Require or result in the constmction of new water or wastewater treatment facilities or expansion of existing facilities, the constmction of which would cause significant environmental effects? c) Require or result in the constmction of new storm water drainage facilities or expansion of existing facilities, the constmction of which could cause significant environmental effects? d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? e) Result in a determination by the wastewater treatment provider, which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? g) Comply with federal, state, and local statutes and regulations related to solid waste?

No Impact. The project proposes constmction of new sewer pipeline and the removal of an existing sewer lift station. The proposed project will improve the reliability of the existing system. The project does not propose to treat or discharge any wastewater. As stated previously, the project will comply with NPDES permit requirements. As a result, no impacts will occur. c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? No Impact. No change to the capacity or fimction of the drainage facility (concrete v-ditches) would occur as a result of the proposed maintenance activities. As a result, no impact will occur. d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? No Impact. The project is the extension of and improvement to an existing sewer infrastmcture and does not propose or necessitate connection to potable water supplies. No water supply impacts are proposed through implementation of the project. As a result, no impact will occur. e) Result in a determination by the wastewater treatment provider, which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? No Impact. The subject project does not include a restroom or other potential sewer-demand generating uses. No wastewater treatment will be required for the project. As a result, no impact will occur. f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? Less Than Significant Impact. The project will not include any components (such as residences or business offices) that would require regular solid waste disposal services over the life of the project. During constmction, demolished portions of the existing sewer lift station would be disposed of in accordance with local, state and federal requirements. Soil excavated during project constmction would be temporarily stockpiled at the staging areas and would be reused, as appropriate, to fill trenches following pipe placement. While the project will generate some debris that would require disposal, it will be relatively minimal. As a result, impacts to landfills will be less than significant. g) Comply with federal, state, and local statutes and regulations related to solid waste? Less Than Significant Impact. The city will comply with statutes and regulations related to solid waste. Any solid waste generated on the site during maintenance activities that cannot be reused elsewhere or processed as green waste would be removed and disposed of in an appropriate facility in accordance with applicable local, state, and federal regulations. As a result, impacts will be less than significant. 56 Rev. 07/06/11 ELA 12-01 VANCOUVER STREET HDD SEWER EXTENSION Potentially Significant Potentially Unless Less Than Significant Mitigation Significant No Impact Incorporated Impact Impact XVIII.

Potentially Significant Unless Mitigation Incorporated. The proposed project is necessary for system reliability of the existing sewer infrastmcture. Biological impacts associated with the proposed project are minimal and involve temporary indirect impacts resulting from constmction disturbance. These impacts will be mitigated (Mitigation Measure BIO-1) throughout implementation of the project to a level below significant. Also, activities will be timed to ensure that wildlife is not significantly affected during the nesting season by the maintenance activities. Cultural resources may exist in the vicinity of the existing lift station demolition and manhole excavation on Vancouver Street. Mitigation measures (CUL-1 through CUL-3) to address potential impacts to cultural resources will be implemented as part of the project and will reduce potential for impacts to a less than significant level. As a result, with the implementation of the mitigation measures, impacts will be reduced to a level of less than significant. b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable 57 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects.) Less than Significant Impact. The project's incremental effects are not anticipated to contribute substantially to cumulatively considerable impacts. The project involves the removal of the existing sewer lift station, which is located within a designated Hardline Conservation Area, as shown in Figure 28 of the city's Habitat Managed Plan (HMP), as Amended November 2004. The project also includes the relocation and extension of a below-grade gravity sewer pipeline between Vancouver Street and Via de Canto Street. The impacts resulting from implementation of the project, including potentially additive impacts to traffic, noise, air quality, and biological resources are not considered cumulatively considerable due to the extremely low magnitude and the short duration of impacts resulting from constmction activities. As a result, impacts will be less than significant. c) Does the project have environmental effects, which will cause substantial adverse effects on human beings, either directly or indirectly? No Impact. As stated above, the project involves the removal of the existing sewer lift station and the relocation and extension of a below-grade gravity sewer pipeline. The project does not have environmental effects that will cause substantial adverse effects on human beings, either directly or indirectly. Potential adverse effects on the human population have been evaluated in preceding sections of this checklist. No immitigable adverse environmental effects attributable to the project have been identified. As a result, no impacts will occur. 58 Rev. 07/06/11 EIA 12-01 VANCOUVER STREET HDD SEWER EXTENSION XVIII.

This fencing shall be installed in all areas adjacent to protected open spaces, and shall be installed prior to constmction, and maintained for the duration of constmction activity. Fencing shall be installed in a manner that does not impact habitats to be avoided. The applicant shall submit to the City for approval, at least seven days prior to initiating project impacts, the final plans and photographs for initial clearing and gmbbing of habitat and project constmction. These final plans shall include photographs that show the fenced limits of impact and all areas to be impacted or avoided. If work occurs beyond the fenced or demarcated limits of impact, all work shall cease until the problem has been remedied and mitigation identified, to the satisfaction of the biological monitor. Temporary orange constmction fencing shall be removed upon project completion of constmction of the project. BIO-2 The developer shall hire a biological monitor to monitor the constmction operations. The biological monitor shall have the ability to hah constmction work, if necessary and confer with the city and Wildlife Agencies to ensure the proper implementation of species and habitat protection measures. The biologist shall report any violation to the USFWS within 24 hours of its occunence. The biological monitor shall be present to monitor clearing, grading, and constmction activities in the vicinity of biological open space areas. The biological monitor shall have the authority to stop constmction and require additional precautions or conservation measures to protect the proposed open space preserve areas, including the wildlife movement corridor, as necessary. Implementation of this measure shall be verified by the city prior to and concunent with constmction. BIO-3 Prior to the commencement of any ground-disturbing activities (i.e., drilling, trenching, grading) that occur between January 15 and September 15, a biological survey by a qualified biologist shall be conducted of the project area. If active raptor and/or migratory bird nests are observed during the constmction phase, a buffer area of adequate width (typically 500 feet), as detennined by the monitoring biologist, shall be established between the constmction activities and the nest so that nesting activities are not intermpted. To avoid potential impacts, trees shall be removed outside of the breeding season of local raptor species (trees shall be removed between September 15 and January 15). Noise attenuation and buffer (if required) shall remain in place until the constmction activities are completed or the nest is no longer active. Implementation of this measure shall be verified by the city. BIO-4 Constmction noise created during the breeding season that could affect the breeding of the Califomia gnatcatcher, migratory songbirds and other bird species associated with the adjacent coastal sage scmb habitat shall be avoided. This restriction can be waived by the city, with concunence from the Wildlife Agencies, upon completion of a breeding/nesting bird survey ofthe area in accordance with the Migratory Bird Treaty Act. A biological monitor of the constmction operation is required.

A completed and signed checklist for each mitigation measure indicates that this mitigation measure has been complied with and implemented, and fulfills the City's monitoring requirements with respect to Assembly Bill 3180 (Public Resources Code Section 21081.6). Mitigation Measure Monitoring Monitoring Department Shown on Plans Verified Implementation Remarks BIOLOGICAL RESOURCES BIO-1 - In order to avoid impacts to adjacent open space habitats during construction, all impacted open space interfaces will require temporary orange construction fencing which clearly delineates the edge of the approved limits of grading and clearing and environmentally sensitive areas beyond. This fencing shall be installed in all areas adjacent to protected open spaces, and shall be installed prior to construction, and maintained for the duration of construction activity. Fencing shall be installed in a manner that does not impact habitats to be avoided. The applicant shall submit to the city for approval, at least seven days prior to initiating project impacts, the final plans and photographs for the demolition of the sewer lift station. These final plans shall include photographs that show the fenced limits of impact and all areas to be impacted or avoided. If work occurs beyond the fenced or demarcated limits of impact, all work shall cease until the problem has been remedied and mitigation identified, to the satisfacfion of the biological monitor. Temporary orange construcfion fencing shall be removed upon project completion of construction of the project.
