Project Title: El Camino Real Widening Project (Case No. CDP 98-47) 2. Lead Agency Name and Address: City of Carlsbad 2075 Las Palmas Drive Carlsbad, California 92009-1576 3. Contact Person and Phone Number Sherri Howard, Associate Engineer (760) 438-1161, extension 4427 4. Project Location: The project is located in an approximately 0.3-mile segment of El Camino Real in the City of Carlsbad on both sides of the bridge over Agua Hedionda Creek (Figure 1) . The project site is about 0.9 mile westerly of the intersection of El Camino Real and College Boulevard, and about a mile easterly from the intersection of El Camino Real and Tamarack Avenue. The segment includes the site of the planned future intersection with Cannon Road, just westerly from the bridge over Agua Hedionda Creek. 5. Project Sponsor's Name and Address: City of Carlsbad Public Works - Engineering Department 2075 Las Palmas Drive Carlsbad, California 92009-1576 6. General Plan Designation: The project site is within the route of El Camino Real, a circulation element roadway, as designated in the Carlsbad General Plan. 7. Zoning: The project site is the unzoned right-of-way of El Camino Real. 8. Description of Project: (Describe the whole action involved, including but not limited to later phases of the project, and any secondary, support, or off-site features necessary for its implementation. Attach additional sheet(s) if necessary.) Page 1 of 24 A N 600 0 600 1200 Feet Figure 1 Project Location Shown on 1994 Aerial Photography IREC&N The project is the improvement of El Camino Real for approximately 1,600 linear feet, including the widening of the existing bridge over Agua Hedionda Creek, a segment approximately 440 feet east of the bridge, and a segment approximately 1,020 feet west of the bridge. The project site includes the future intersection of El Camino Real with Cannon Road. The project will include widening the bridge and an area west of the bridge. The bridge is presently 108 feet wide; the project would add two feet to each side for sidewalk to increase the width to 112 feet. The bridge construction will be completed from the current bridge with no impacts from construction to the area below the bridge. El Camino Real would be widened from the bridge westerly by adding up to 17 feet to the width of paving on the north side and up to 29 feet to the width of paving on the south side. The widening would result in a paved width for El Camino Real of 106 feet east of the Cannon Road intersection and 138 feet west of that intersection to allow for planned geometry and striping at the future intersection with Cannon Road to the south. Construction of Cannon Road to the south of the intersection is not a part of this project, but will be constructed at the same time, and the proposed project has been coordinated with plans for the construction of that segment of Cannon Road. The Carlsbad Circulation Element shows Cannon Road extending northeasterly from El Camino Real to where Cannon Road presently stubs out at the City limit in Oceanside, but that extension is not an active project at this time. Project plans do include, however, an extension of paving northerly from the El Camino Real/Cannon Road intersection to an existing blacktop road giving access to properties in that area. This Initial Study is based on a review of project plans available at the time the study was prepared. During the course of the Initial Study, a modification of the project was developed which reduces biological impacts of the proposed project but for which engineering plans are not available. This alternative is referred to in the biological report as the Reduced Impact Alternative. It would reduce the length of the free right-turn lane from El Camino Real onto Cannon Road by 150 feet and avoid construction in any wetland area (Figure 2). The City Engineering Department has agreed to implement this modification of the project, and final plans for construction will reflect it. The assessment of impacts and mitigation in this Initial Study uses the reduced impact alternative as the project. 9. Surrounding Land Uses and Setting: (Briefly describe the project's surroundings. Attach additional sheet(s) if necessary). On the north side of El Camino Real, just easterly from the project site, is a mobile home park. Other areas around the project site are presently mostly vacant and undeveloped, although there are widely scattered residences to the north. A plant nursery is located in the area adjacent to El Camino Real just west of the mobile home park. Agua Hedionda Creek flows northwesterly through the mobile home park. Just north of the mobile home park and El Camino Real, it is joined by another drainage from the east. Agua Hedionda Creek flows south under the El Camino Real bridge and then turns westward under the future route of Cannon Road. The creek then flows generally westward into the wetlands of Agua Hedionda Lagoon.

This area to the south is known as Kelly Ranch and is presently vacant and mostly undeveloped, but is the site of proposed future residential development. Development of Kelly Ranch will include the construction of Cannon Road south from El Camino Real, including the Cannon Road/El Camino Real intersection. 10. Other Public agencies whose approval is required (e.g., permits financing approval, or participation agreement): California Department of Fish and Game (CDF6): The proposed project may require an agreement under Section 1601 of the California Fish and Game Code for a streambed alteration associated with the road widening and drainage improvements. The agreement would be required if the Department, in reviewing the project, determines that the disturbed mule fat scrub impacted by the project is a vegetative community associated with the Aqua Hedionda Creek streambed. ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact" as indicated by the checklist on the following pages. Land Use and Planning Population and Housing Geological Problems Water Air Quality Paleontology Transportation/Circulation Biological Resources Energy and Mineral Resources Hazards Noise Mandatory Findings of Significance Public Services Utilities and Service Sys. Aesthetics Cultural Resources Recreation DETERMINATION: On the basis of this initial evaluation: I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described in the environmental checklist have been added to the project. A MITIGATED NEGATIVE DECLARATION will be prepared. The mitigation measures required are listed in Appendix A. Signature Date Printed Name For Page 5 of 24 c EVALUATION OF ENVIRONMENTAL IMPACTS 1) A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parenthesis 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 where it is based on project-specific factors as well as general standards. 2) All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. 3) "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "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" Hie lead agency must describe the mitigation measure, and briefly explain how they reduce the effect to a less than significant level. 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063 (c) (3) (D). Earlier analyses are discussed in Section XVn at the end of the checklist 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts. References to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. Page 6 of 24 POTENTIALLY SIGNIFICANT POTENTIALLY UNLESS LESS THAN SIGNIFICANT MTTIOATION SIGNIFICANT NO IMPACT INCORPORATED IMPACT IMPACT Would the proposal result in potential impacts involving: LAND USE & PLANNING. Would the proposal: a) Conflict with general plan designations or \ ) j | | | zoning? The project consists of improvements to a Circulation Element road in the city of Carlsbad and is consistent with the General Plan. b) Conflict with applicable environmental plans or | | | | E?| | | policies adopted by agencies with jurisdiction over the project? The project will affect wetlands associated with Agua Hedionda Creek, but permits from the appropriate resource or trustee agencies (USACE and CDFG) will be required for project implementation, and adequate mitigation for impacts to biological resources is included in the project (see Section VII below) . c) Be incompatible with existing land use in the | | | | | | E£| vicinity? The project is the widening of an existing major street and would not change any land use in the vicinity. d) Affect agricultural resources or operations? | | | [ | | E?| No agriculture is currently being conducted on any of the land that is within the limits of work indicated on project plans. A horticultural nursery north of El Camino Real in the project area will not be affected. e) Disrupt or divide the physical arrangement of an | | | | | | [^ established community? El Camino Real already is constructed in this alignment. The only established community or neighborhood in the project vicinity is the mobile home park northeast of the future intersection. The physical arrangement of the mobile home park would not be affected by the proposed project. Page 7 of 24 c POTENTIALLY SIGNIFICANT POTENTIALLY UNLESS LESS THAN SIGNIFICANT MITIGATION SIGNIFICANT NO IMPACT INCORPORATED IMPACT IMPACT E. POPULATION & HOUSING. Would the proposal: a) Cumulatively exceed official regional or local \ \ \ } | \ population projections? The project is the widening of an existing road and would have no effect on either regional or local population projections. b) Induce substantial growth in an area either directly \ \ \ | [""] ^\ or indirectly (e.g. through projects in an undevel- oped area or extension of major infrastructure)? The project is intended to serve population and development growth consistent with the Carlsbad General Plan and to make road improvements consistent with the General Plan's Circulation Element. c) Displace existing housing, especially affordable | ) | | j~"| housing? No housing would be affected by the project. GEOLOGICAL PROBLEMS. Would the proposal result in or expose people to potential impacts involving: a) Fault rupture? |~| f~| E3 |~| A geotechnical evaluation of the project performed for the project by Ninyo & Moore in June of 1998 is included in this Initial Study as Attachment A. Responses in this section are based on that report. In addition, a comprehensive geotechnical evaluation of the project will be performed and reviewed by the City prior to final approval of construction plans. Like all of southern California, the site is in a seismically active area. The most significant maximum credible earthquake event that could affect the project site is considered to be an earthquake of magnitude 7.0 on the Rose Canyon fault zone. The geotechnical evaluation concluded, based on a review of pertinent literature, that no active faults have been mapped across the project site, and that the potential for ground surface rupture at the site is low. Page 8 of 24 POTENTIALLY SIGNIFICANT IMPACT POTENTIALLY SK3NIF1CANT UNLESS MITIGATION INCORPORATED LESS THAN SIGNIFICANT IMPACT b) Seismic ground shaking?D NO IMPACT D The geotechnical evaluation of the project concluded that construction of the project is feasible from a geotechnical perspective. The project site is in Seismic Zone 4 of the Uniform Building Code, and there is a potential for strong ground motions to occur at the site. Before final plans for the project are approved, a comprehensive geotechnical evaluation will be required by the City in which the potential for ground shaking will be considered. Feasible mitigation by means such as compaction of soil materials and roadbed preparation is available, and the project would widen portions of an existing road, not construct a new road. Under these conditions, the risk from ground shaking is not considered significant. c) Seismic ground failure, including liquefaction?D D D The presence of loose, granular soils and the shallow depth of groundwater at the site increase the potential for liquefaction and dynamic settlement at the site. The project does not propose to modify or create deep foundational elements such as bridge pilings, and will not increase the risk of ground failure or liquefaction. d) Seiche, tsunami, or volcanic hazard? I I I I I I R?j Conditions for seiche or volcanic hazard do not exist at or near the project site. The geotechnical evaluation finds the potential for damage due to tsunami to be very low, based on the location approximately 2.5 miles from the coastline. e) Landslides or mudflows?D D D There is no high ground adjacent to the project area that would present the danger of landslides or mudflows that could affect the roadway. f) Erosion, changes in topography or unstable soil \ | | | conditions from excavation, grading, or fill?D Project plans include an erosion control plan for construction and the stabilization and control of runoff by means of slope armoring, storm drains, and energy dissipators as part of the completed project. g) Subsidence of the land?D The project would not include any features, such as mining or groundwater withdrawal, that could cause land subsidence. Page 9 of 24 c POTENTIALLY SIGNIFICANT IMPACT POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED LESS THAN SIGNIFICANT NO IMPACT IMPACT h) Expansive soils?D D D The geotechnical evaluation did not find expansive soils to be a problem at the site. However, the fill and alluvial soils that characterize the site may induce unacceptable settlement. Subsurface investigation and laboratory testing will be required to address the potential. Such testing will accompany the compre- hensive geotechnical evaluation that will be required by the City prior to project implementation. i) Unique geologic or physical features?D D Geologic and physical conditions of the site are typical of the location, without any remarkable or unique features. IV. WATER. Would the proposal result in: a) Changes in absorption rates, drainage patterns, or the rate and amount of surface runoff?D D D A water quality evaluation was prepared for the proposed project in June of 1998 and is included in this Initial Study as Attachment B. Responses below are based on that study. There would be a slight, but not significant, increase in runoff due to the increase in the area of paved and other impermeable surfaces. The project will not affect Agua Hedionda Creek, for which channel improvements will be constructed as part of the Cannon Road construction project. Runoff from reconstructed El Camino Real will be controlled and released through energy dissipators into existing drainage patterns. During construction, the project will be required to comply with Best Management Practices for control of runoff through the National Pollution Discharge Elimination System (NPDES) permit requirements of the federal Clean Water Act. b) Exposure of people or property to water related hazards such as flooding?D D Bridges and channel improvements are designed to avoid flooding in a design storm of 100-year frequency. Page 10 of 24 o POTENTIALLY SIGNIFICANT POTENTIALLY UNLESS LESS THAN SIGNIFICANT MITIGATION SIGNIFICANT NO IMPACT INCORPORATED IMPACT IMPACT c) Discharge into surface water or other alteration | | | | j^ j | of surface water quality (e.g. temperature, dissolved oxygen, or turbidity)? Project plans include an erosion and runoff control plan during construction. Areas disturbed by construction will be stabilized when construction is completed, and runoff from the road surfaces will be stabilized and controlled principally into drains with energy dissipators at the outlets of the drains. Construction of the project will be subject to the requirements of the NPDES permitting process, which will require the employment of Best Management Practices for the control of water quality. d) Changes in the amount of surface water in any j | | \ |~] ^ water body? Runoff from the project site will be directed into drains and will eventually drain into Agua Hedionda Creek and the Agua Hedionda Lagoon. The volume of runoff from the relatively small area of increase in paved surfaces, however, will not appreciably affect the amount of surface water in these water bodies. e) Changes in currents, of the course or direction of |~] | | [""] R?l water movements? The patterns, currents, courses, and direction of drainage into Agua Hedionda Creek and Agua Hedionda Lagoon will not be substantially affected by the project. The planned drainage control measures for the completed project will discharge runoff in ways similar to the existing course and direction of runoff flows. f) Change in the quality of ground waters, either | [ | \ \ \ through direct additions or withdrawals, or through interception of an aquifer by cuts or excavations or through substantial loss of groundwater recharge capability? Withdrawal or addition to groundwater is not a part of the proj- ect, and grading for construction will not result in cuts deep enough to affect any groundwater aquifer. Page 11 of 24 POTENTIALLY SIGNIFICANT POTENTIALLY UNLESS LESS THAN SIGNIFICANT MITIGATION SIGNIFICANT NO IMPACT INCORPORATED IMPACT IMPACT g) Altered direction or rate of flow of groundwater? | | | | | [ Although the groundwater table is relatively high at the project site, deep excavation is not proposed and construction dewatering is not anticipated. If temporary construction dewatering should occur and the effluent is released to surface waters such as Agua Hedionda Creek, then the discharge will be required to meet the effluent limits specified by the Regional Water Quality Control Board (Order No. 96-41/NPDES CAG919002). h) Impacts to groundwater quality? | | | | f>^] | | Some runoff from the project may percolate to groundwater, since the water table in the project vicinity is relatively high. For a discussion of potential impacts, see the response to IV.a above. i) Substantial reduction in the amount of j | | j f"~] groundwater otherwise available for public water supplies? No use of groundwater is proposed. V. AIR QUALITY. Would the proposal:. a) Violate any air quality standard or contribute to | [ | | [' J an existing or projected air quality violation? Emissions will result from internal combustion engines used to power construction equipment and from traffic to and from the site during construction. Motorized construction equipment is regulated by Air Pollution Control District (APCD) rules and must comply with APCD emissions standards. Motor vehicles licensed for road use are regulated for pollution control by the state Department of Motor Vehicles. b) Expose sensitive receptors to pollutants? j | | | [~| |^| No unusual pollutants or amounts of pollutants would be generated by construction of the proposed project. See the preceding response. c) Alter air movement, moisture, or temperature, or j | | | j \ cause any change in climate? The project will not be of a scale or nature to significantly affect meteorological factors. Page 12 of 24 POTENTIALLY SIGNIFICANT IMPACT POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED LESS THAN SIGNIFICANT IMPACT NO IMPACT d) Create objectionable odors? | | | | No objectionable odors would be produced. VL TRANSPORTATION/CIRCULATION. Would the proposal result in: a) Increased vehicle trips or traffic congestion? j | | | Construction of the project may cause some disturbance of normal traffic patterns on El Camino Real. Project plans include traffic control and temporary striping plans to minimize the disruption of traffic during construction. When completed, the project will improve traffic flow in the project area. b) Hazards to safety from design features (e.g. sharp curves or dangerous intersections or incompatible uses)? [""] | | The project has been designed to meet applicable City design standards. Road widening and lane geometry are designed to City standards, and the wider road will allow design for greater safety. c)Inadequate emergency access or access to nearby uses? | ||~~| | | There will be no restriction of emergency access to the site or to any other area. During construction of the project, alternate routes will be available to areas where construction restricts any access route to nearby properties. Project plans include the provision of access to nearby uses north of El Camino Real from the Cannon Road intersection. d) Insufficient parking capacity on-site or off-site?| | l~~|| | No features of the project would affect public parking. e) Hazards or barriers for pedestrians or bicyclists?j | | | Except for possible temporary obstruction during construction, no part of the project will adversely affect pedestrian or bicycle routes. Bike lanes in both directions will be provided as part of the completed project, and widening the bridge will allow pedestrian sidewalks. Page 13 of 24 POTENTIALLY SIGNIFICANT POTENTIALLY UNLESS LESS THAN SIGNIFICANT MITIGATION SIGNIFICANT NO IMPACT INCORPORATED IMPACT IMPACT f) Conflicts with adopted policies supporting | | | | | \ alternative transportation (e.g. bus turnouts, bicycle racks)? Bike lanes will be provided by the completed project in accordance with City policies. g) Rail, waterbome, or air traffic impacts? |"~| j| | | R?| The project will not affect any of these modes of transportation, either directly or indirectly. VIL BIOLOGICAL RESOURCES. Would the proposal result in impacts to: a) Endangered, threatened or rare species or their \ \ ^j j \ \ \ habitats (including but not limited to plants, fish, insects, animals, and birds)? The project was the subject of field surveys and biological evaluation in May of 1998. Responses in this section are based on the biological report for the project that is included in this Initial Study as Attachment C. The project evaluated in this checklist is the Reduced Impact Alternative described in the biological report, since the City has agreed to implement that alternative (see Figure 2). Biological surveys of the site discovered no endangered, threatened* or rare species on the site. Sensitive bird species may use riparian habitats on or near the site. To avoid direct impacts to these species, a biologist shall survey the site prior to the start of construction to assure potential nesting species are not disturbed (see Appendix A). b) Locally designated species (e.g. heritage trees)? j~"| | | | } ^ No locally designated species are present on the project site. Mitigation listed in Appendix A would avoid impacts to all species with the potential to occur on the site that are covered in the draft Habitat Management Plan for Natural Communities in the City of Carlsbad (December 1, 1997). Page 14 of 24 w POTENTIALLY SIGNIFICANT POTENTIALLY UNLESS LESS THAN SIGNIFICANT MITH3ATION SIGNIFICANT NO IMPACT INCORPORATED IMPACT IMPACT c) Locally designated natural communities (e.g. oak | | ^j | j | [ forest, coastal habitat, etc.)? The project would affect 0.35 acre of coastal sage scrub and 0.32 acre of mule fat scrub, natural communities designated for conservation in the draft Habitat Management Plan for Natural Communities in the City of Carlsbad (December 1, 1997) . The mule fat scrub affected is not a wetland according to USAGE criteria. Mitigation for impacts to these communities will be accomplished by restoration of 0.31 acre of higher-quality mule fat scrub and 0.39 acre of higher-quality coastal sage scrub on-site when construction is completed (see Appendix A) . The project would also affect a very small amount of wetland habitat from shading by the widened bridge. Because there would be no ground area of wetland affected, and only a small area of tree canopy affected, this effect is not considered significant. d) Wetland habitat(e.g. marsh, riparian and vernal { | ^j | | | | pool)? As originally proposed, the project would have permanently impacted 0.03 acre of alkali marsh and temporarily impact 0.01 acre of alkali marsh. It would also have permanently impacted 0.10 acre of disturbed mule fat scrub) and temporarily impacted an additional 0.22 acre of disturbed mule fat scrub. The disturbed mule fat scrub affected does not meet USAGE criteria for wetland habitat but may qualify as a wetland under CDFG jurisdiction. The Reduced Impact Alternative, which the City has agreed to implement, would eliminate the project's impacts to any habitat defined as a wetland by USAGE criteria, other than a very small amount of increased shading of freshwater marsh and southern willow scrub by the widened bridge (see the preceding response). Mitigation for impacts of the reduced impact alternative are presented in Appendix A. e) Wildlife dispersal or migration corridors? | | | | £>?] | | The biological report for the proposed project concludes that because of the quality and location of natural communities in the project area, and the presence of El Camino Real as an existing feature, impacts on wildlife movement corridors will not be significant. Vffl. ENERGY & MINERAL RESOURCES. Would the proposal: a) Conflict with adopted energy conservation plans? | | | | | | Energy will be consumed by construction equipment. That expendi- ture will be required to implement the project and does not conflict with adopted energy conservation plans. Page 15 of 24 POTENTIALLY SIGNIFICANT POTENTIALLY UNLESS LESS THAN SIGNIFICANT MITIGATION SIGNIFICANT NO IMPACT INCORPORATED IMPACT IMPACT b) Use non-renewable resources in a wasteful and | | | | | | inefficient manner? See the preceding response. Energy and materials will be consumed during construction, and some of this expenditure will be from non-renewable resources. No evidence for wasteful or inefficient use of non-renewable resources has been identified. c) Result in the loss of availability of a known j { | | |j |S?| mineral resource that would be of future value to the region and the residents of the state? A geological reconnaissance of the site revealed no known or expected mineral deposits of significant economic value that would be affected by the project (see Attachment A). LX. HAZARDS. Would the proposal involve: a) A risk of accidental explosion or release of | | | j | | hazardous substances (including but not limited to: oil, pesticides, chemicals or radiation)? The proposed project was the subject of a hazardous materials evaluation, including review of maps, photographs, and documents and a site reconnaissance by Ninyo & Moore in June of 1998. A report on the evaluation is included in this Initial Study as Attachment D. Responses in this section are based on that report. No extraordinary risk of this nature is anticipated. Any trans- portation, storage, use, and disposal of hazardous substances during construction will be conducted according to all applicable state, federal, and local regulations. No chemicals or hazardous substances will be stored at the project site. b) Possible interference with an emergency response | | | | ££| [ | plan or emergency evacuation plan? Construction of the project would affect traffic on El Camino Real. Project plans include traffic control and temporary striping plans to maintain through routes in the project area during construction. c) The creation of any health hazard or potential | | | { | } |^| health hazard? No potential or actual health hazards would be associated with the project. Any use or temporary storage of hazardous materials at the site during construction will be subject to all applicable federal, state, and local laws and regulations. Page 16 of 24 c POTENTIALLY SIGNIFICANT POTENTIALLY UNLESS LESS THAN StCrOFICANT MITIGATION SIGNIFICANT NO IMPACT INCORPORATED IMPACT IMPACT d) Exposure of people to existing sources of [""] j | \ | potential health hazards? There are no known health hazards associated with the project. According to the hazardous materials evaluation performed for the project, there is no known repository of hazardous materials in the project area. e) Increased fire hazard in areas with flammable j"~j | | | j ^| brush, grass, or trees? The proposed project would not be susceptible to damage by ordinary wildfires and will not increase the presence of unprotected, flammable structures or substances on the site. X. NOISE. Would the proposal result in: a) Increase in existing noise levels? \~~\ \ | \\ ^) Ambient noise at the project site was measured in May of 1998 and the noise effects of the project assessed in a technical report. Responses in this section are based on that report, which is included in this Initial Study as Attachment E. Construction of the project would at times generate higher than usual levels of noise. A mobile home park is located north of El Camino Real just east of the project area, and may be affected by construction noise. This effect would be temporary and would be restricted to normal working hours of the day. After construction, the project would not result in any significant change in the distance from the source of traffic noise to the mobile home park and would not change the composition or volume of traffic using El Camino Real. For the mobile home park, there would be no change in future noise conditions as a result of the project, and no other sensitive off-site receptors would be affected. b) Exposure of people to severe noise levels? | j See the preceding response. Construction noise would be temporary and restricted to usual weekday working hours. The completed project would have no significant effect on noise levels in the project area, compared to conditions that would prevail if the project were not implemented.

It would not substantially affect other public services. Xn. UTELITIES & SERVICE SYSTEMS. Would the proposal result in a need for new systems or supplies, or substantial alterations to the following utilities: a) Power or natural gas? I II I E^l I I Like many public roads, the El Camino Real right-of-way serves as the route for a number of underground utility conveyance lines. Project plans identify these utilities and require the construc- tion contractor to avoid or properly relocate them. Coordination with the utility operated will also be required of the contractor. Under these conditions, no unforeseen interruption or substantial alteration of power, natural gas, or other utilities is expected. b) Communications systems? | | | | j^ [ | See the preceding response.

Would the proposal: a) Disturb paleontological resources? | | F?| | | | | The project is located in an area geologically characterized by recent alluvium and fill overlying the Eocene-age Santiago Formation. Excavation during construction could disturb the Santiago Formation, which is approximately 45 million years in age and has produced significant fossil finds in the areas relatively near the project site. If important fossils were destroyed during construction of the project, the impact would be significant. The impact can be mitigated to a level less than significant by requiring a paleontological monitor to be on-site during initial cuts that would affect the Santiago Formation. The paleontologist would be empowered to salvage and curate any significant fossils, which would be donated to a museum collection (see Appendix A) . b) Disturb archaeological resources? | ] [ | ["""] E?I Cultural resource records were reviewed and a field survey for cultural resources in the project area was conducted in April of 1998. A report on the record search and field survey is included in this Initial Study as Attachment F. Based on the cultural resources report, no archaeological or historical resources would be affected by construction of the project within the construction limits shown on project plans. c) Affect historical resources?

Earlier analyses used where, pursuant to the tiering, program EIR, or other CEQA process, one or more effects have been adequately analyzed in an earlier EIR or Negative Declaration. (Section 15063(c)(3)(D).) In this case a discussion should identify the following: a) Earlier analyses used. Identify earlier analyses and state where they are available for review. No earlier analyses for this project were used. b) Impacts adequately addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. No such earlier document was used. c) Mitigation measures. For effects that are "Potentially Significant Unless Mitigation Incorporated," describe, on attached sheets, the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project Mitigation measures for the proposed project and the reduced impact alternative were developed specifically for the project.

MANDATORY FINDINGS OF SIGNIFICANCE. a) Does the project have the potential to degrade the [ | j | j | quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? See responses to Section VII in this checklist. b) Does the project have the potential to achieve short | [ \\ \ | |S?| term, to the disadvantage of long-term, environmental goals? The project is intended to improve the geometry and flow of traffic on a major thoroughfare in the city of Carlsbad. Envi- ronmental impacts are relatively minor, mitigable, and will be mitigated in accordance with long-term environmental and conserva- tion planning for the City and the project area. The project is proposed at this time to accomplish improvements to El Camino Real that are coordinated with planned construction of Cannon Road to the south, avoiding the inefficiency of separately-phased projects affecting the same project area. c) Does the project have impacts that are individually || [ | [""] E?| limited, but cumulatively considerable? The project is a part of the City's Capital Improvements Program to implement the Circulation Element. Cumulative impacts of this project and the Cannon Road project that affects the same project area have been considered and found not to be significant with mitigation required by the City's environmental review of each project and the conditions of permits required from resource and trustee agencies. d) Does the project have environmental effects | | | | [""] |^j which will cause substantial adverse effects on human beings, either directly or indirectly? No such effects have been identified, taking into account the nature and characteristics of the project and recent evaluation of conditions in the project area. Page 23 of 24 DETERMINATION. I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have significant effect(s) on the environment, but at least one potentially significant effect 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. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, 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 pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier ENVIRONMENTAL IMPACT REPORT, including revisions or mitigation measures that are imposed upon the proposed project. Therefore, a Notice of Prior Compliance has been prepared. Planner Signature Date Planning Directory's Signature Date Page 24 of 24 APPENDIX A 1. List of Mitigating Measures 2.

RD - Appendix P. _u June 4, 1998 4241 Jutland Drive, Suite 201 San Diego, CA 92117-3653 619/270-5066 fax 270-5414 Ms. Sheni Howard City of Carlsbad 2075 Las Palmas Drive Carlsbad, CA 92009 DEPARTMENT Reference: Cultural Resource Survey of a Segment of El Camino Real Widening Project Area (RECON Number 3018A) Dear Ms. Howard: This letter report presents the results of the cultural resource investigations for the proposed widening of El Camino Real at its crossing with Agua Hedionda Creek (Figures 1 and 2). The investigations include archival research, historic map review, and a pedestrian reconnaissance survey of the project area. Archival and fieldwork indicate that there are no important cultural resource sites, features, or isolates within the proposed project area and none are anticipated. A 1948 road segment, which extends into the study area, constitutes an historic-era feature within the project; however, alterations and maintenance of this road segment have been extensive in the project vicinity altering any meaningful historic-era association. The proposed project will have no significant impact on this historic-era element. No additional cultural resource work is recommended for this project as proposed, given the results of the current investigation. A review of the existing cultural resource site documents was conducted on April 27,1998, at the South Coastal Information Center at San Diego State University (Attachment 1). This institution is the official State of California repository for such records in San Diego County. A self-search was conducted in order to expedite the collection of pertinent information regarding the study area. Site records, historic maps of the area, and listings of historic landmarks were reviewed. There are no recorded cultural resource sites or historic landmarks within or adjacent to the study area. The historic map review indicated that one historic-era road occurs within the study area. This road which still exists is indicated on the 1948 USGS 7.5' San Luis Rey quadrangle. This road segment has lost its historic appearance and context due to alterations and maintenance. This historic-era feature does not constitute an important historic resource. Within one-half mile of the proposed project a number of historic- and prehistoric-era resources are present The 1948 USGS map indicates a total of three structures, one to the southwest and two to the southeast of the study area. The structure to the southwest appears to be present among a group of structures. None of these structures are recorded as historic-era resource sites. Ten prehistoric sites are recorded within one-half mile of the study area. Most of these sites are situated on the uplands to the south, with a few to the north of the proposed project. Of these sites, eight are reported to be campsites or resource processing locations of limited use. Two of the sites are reported to be larger concentrations of cultural material, both in site size and in deposit content. One of these sites is an upland camp located to the south of the study area while the other is a low- lying midden deposit, situated downstream from the road widening area. The pedestrian survey of the project area was completed on April 28,1998. Resumes of key project personnel are provided in Attachment 2. Near the creek there is a broad area of sand and flotsam which has been deposited at the margins of the creek by runoff from recent periods of high water. Ground surface visibility in these areas varied from poor to good depending on the amount of exposed ground surface. Care was taken to examine all areas within the survey corridor where the ground surface was exposed, for indications of cultural material. Overgrown and obscured areas were not examined, comprising approximately 50 percent of the stream margin. The roadbed for El Camino Real includes a layer of soil fill which extends laterally into the survey area, on either side of PROJECT LOCATION AGUA HEDIONDA LAGOON 2 Af/L£5 0 FIGURE I Regional Location of the Project PROJECT LOCATION ^Sintorosa i.Country Club 'Aqua ' jiil Map Source: U.S.G.S. 7.5 minute topographic map, II San Luis Rey quadrangle 400 200 FEET 0 FIGURE 2 Project Location Ms. Sherri Howard Page 2 June 4, 1998 the pavement. The fill soil forms a bank that is occasionally buttressed along the study segment with rip rap. This portion of the project was considered to have the lowest potential to yield cultural material. The northwest portion of the survey area supports a thick growth of weeds, brush, and trees. The surveyed areas closer to the stream have been cleared of these (Photograph 1), creating fair to good ground surface visibility. Some areas of swampy ground were not inspected closely because of potential hazards and areas covered with accumulated debris were obscured. The remainder of the northwest portion of the project area was composed of clean sand. The southwest portion of the survey area is bounded by an improved dirt road. The area between the road and the stream supports a dense stand of willow and other riparian flora. The growth was impenetrable and was visually inspected along the margins. The surface visibility in this area was poor but the existing conditions did not suggest that archaeological debris was likely. The opposite flank of the dirt road is dominated by a marsh that was not surveyed (Photograph 2). The marsh extends to the edge of the fill bank of El Camino Real and occupies virtually all of the survey area in this quadrant. A mobile home community occupies the southeast portion of the project area (Photograph 3). Development of the mobile home community has extensively altered the natural ground surface. A palm tree nursery occupies the northeast portion of the study area (Photograph 4). This area has been graded level and is clear of vegetation. The ground surface visibility in this area was excellent in the rows between the trees. The results of the pedestrian survey were negative. No indications of prehistoric cultural resources were identified within the study area. Historic materials and debris were limited to recent trash and litter. The dynamic nature of the stream has probably had a limiting effect on the selection of this location for settlement during either the prehistoric or early historic periods. Site record information indicates that archaeological sites exist at a somewhat greater distance from the stream. Selectivity of site location has likely contributed to the absence of cultural materials within the study area. No additional cultural resource investigations are recommended for the El Camino Real widening project as proposed, based on the results of the documentary research and pedestrian survey. However, alterations to the proposed project that would extend beyond the areas covered would necessitate additional investigations to evaluate potential impacts in those areas.

On July 13,1998, Fred Sproul, biologist, and Greg Evans, Landscape Architect, surveyed the proposed site along El Camino Real to determine if vegetation identified by City environmental consultant RECON is indeed wetland vegetation as defined by U. S. Army Corps of Engineers guidelines. Our assessment of existing the vegetation follows. The project site is comprised of the roadway edge, an existing manufactured slope supporting the raised roadbed, and a bench area that transitions from this upland condition to a wetland corridor west of the project area which is linked to Upper Agua Hedionda Lagoon. The linear study area extends from the proposed Cannon Road R.O.W. northward along El Camino Real approximately 500 feet to an existing box culvert providing drainage beneath El Camino Real from points east. An area of Mulefat scrub, approximately 0.10 acre in size, occurs on a bench within the present construction zone, located approximately between roadway Station 447+50 and Station 449+75. Mulefat Scrub is identified on-site where Mulefat (Baccharis salicifolia) is the dominant vegetative cover. On the site it occurs in association with several other plants including: Western ragweed (Ambrosia psilostachya). Coyote brush (Baccharis pilularis var. consanguinea) and Saltgrass (Distichilis spicata). This community is bordered on its lower boundary by weed infested Ruderal vegetation. That these plants occur in association identifies this area as a transitional community between an upland plant association and a wetland plant association. ^ None of the plants occurring in this Mulefat scrub are identified as obligate wetland species as identified in the "National List of Plant Species That Occur in Wetlands: California Region O", May 1988. Several of the dominant species observed are equally likely to occur in upland or wetland conditions. Some of the dominant species observed are facultative or obligate upland plants. To be considered a jurisdictional wetland, the U.S. Army Corps of Engineer's (USACOE) requires that three wetland components occur simultaneously: wetland 21 u PALOMAR AIRPORT ROAD • SUITE 100 • CARLSBAD.

Two pits in excess of 24" deep were dug to examine ground water and soil characteristics in the Mulefat scrub area. The results failed to show either hydrologic or wetland soil characteristics. A Wetland Determination of the subject Mulefat scrub was performed (see attached Wetland Determination). The results conclude that the subject Mulefat scrub is not a wetland. We recommend that the City minimize impacts to this transitional plant community. Impacts to Mulefat scrub can be lessened by strictly limiting the construction zone. We recommend that revegetation of a transitional community similar to the existing Mulefat scrub is accomplished in post-construction areas presently supporting ruderal vegetation. Sincerely?

The following materials were consulted as part of this review: The ND, inclusive of the Environmental Impact Assessment Form dated September 25, 1998, the "Biological Technical Report for the El Camino Real Road Widening Project, Carlsbad, California" (RECON, September 18, 1998), a letter report which discusses the results of a cultural resource survey for the El Camino Real widening project (RECON, June 4, 1998), and the "Noise Technical Report for the El Camino Real Road Widening Project, City of Carlsbad, California" (RECON, June 3, 1998). The project site is located along El Camino Real, between College Boulevard and Tamarack Avenue, just north of Evans Point. The existing road crosses Agua Hedionda Creek and includes the future intersection with Cannon Road. The project to be implemented is the "Reduced Impact Alternative" discussed in the biological report which would widen the roadbed and the bridge crossing over Agua Hedionda Creek from 108 feet to 112 feet, construction of an access road north of El Camino Real, and the construction (or reconstruction) of two energy dissipaters. Site elevation is approximately 40 feet above mean sea level (ASML); underlying soils are predominantly Salinas clay loam with areas of riverwash in Agua Hedionda Creek.. Native or naturalized habitats which occur in the project area include the following: alkali marsh, mulefat scrub, Diegan coastal sage scrub, and non-native grassland. No sensitive plant or animal species were identified during the field surveys, however focused surveys do not appear to have been conducted for sensitive animal species. Project implementation will result in both temporary and permanent impacts to the following habitats: disturbed mulefat scrub (0.22 acre temporary/0.10 acre permanent), Diegan coastal sage scrub (0.06 acre temporary/0.29 acre permanent), Eucalyptus woodland (0.09 acre temporary/0.09 acre permanent), and non-native grassland (0.07 acre temporary/0.14 acre permanent). The remaining impacts would involve disturbed or developed areas. Mitigation is proposed at a ratio of 1:1 and would be accomplished through revegetation of temporarily affected areas and newly-constructed manufactured slopes. Potential indirect impacts to sensitive breeding bird species are proposed to be mitigated through performance of clearance surveys if vegetation removal and/or grading would occur between March 1 and September 30, annually. Mr. Christer Westman 2 The mitigation measures proposed in the ND do not adequately compensate for biological impacts which will result from project implementation and are not consistent with measures generally recommended by the Wildlife Agencies. As such, we recommend the following: 1. Mitigation through restoration or enhancement of habitat which is implemented concurrent with project impacts requires a ratio of at least 2:1 to compensate for the temporal loss of habitat function and value to wildlife. Therefore, the amount of coastal sage scrub and mulefat scrub to be restored would need to be 0.70 acre and 0.64 acre, respectively. Should mitigation for coastal sage scrub impacts be through the purchase of habitat in a mitigation bank or area approved by the Wildlife Agencies, the mitigation ratio would be 1:1 (0.35 acre). Any restoration program should include specific, measurable success criteria as well as a discussion of remedial measures to be put in place should the program not meet targeted milestones. Monitoring should be conducted for no less than three years. The success criteria included in the Biological Opinion for Cannon Road Reaches 1 and 2 (1-6-97-F-51) would be acceptable for the mulefat scrub restoration program. 2. To avoid direct and/or indirect impacts to sensitive bird species, vegetation removal and grading activities should not occur during the breeding season which is considered to be from February 15 through September 15, annually. [This encompasses the breeding season for both the coastal California gnatcatcher and least Bell's vireo.] If this cannot be accomplished, the City should consult with the Wildlife Agencies to develop alternative mitigation strategies (e.g. pre-construction surveys for species presence, nests, etc.) which, when implemented, will mitigate impacts. 3. This project would require formulation of a Streambed Alteration Agreement. Please contact Ms. Terri Dickerson (Department) at (949) 363-7538 to obtain a Section 1601 package. The ND does not discuss how the City intends to permit the loss of coastal sage scrub which would result from this road widening project. As the impacts to coastal sage scrub are less than one acre, the loss could be accounted for through the use of the de minimus exemption to the 4(d) Special Rule if these two additional criteria can be met: a) the impact is less than one acre; and b) habitat loss would not compromise conservation planning efforts in the area. The use of this exemption still requires mitigation and the deduction of the impact amount from the City's five percent allotment. A major difference between the de minimus exemption and a habitat loss permit (HLP) is that the former may still be used absent sufficient five percent remaining in the City's allotment. Should surveys demonstrate that coastal California gnatcatchers are not present in the project area, the Wildlife Agencies would not object to the use of the de minimus exemption for this project. We appreciate the opportunity to review this ND for the El Camino Real road widening project.

Tippets Habitat Conservation Supervisor CALIFORNIA DEPARTMENT OF FISH AND GAME 4949 Viewridge Avenue San Diego, CA 92123 MITIGATED NEGATIVE DECLARATION FOR THE EL CAMINO REAL WIDENING PROJECT Dear Mr. Tippets: The following information is in response to your department's letter of comment, dated October 22, 1998 (CDP 98-47) on the City's Mitigated Negative Declaration (MND) for the above-referenced project. On November 17, 1998, Sherri Howard and Christer Westman of the City met on the site of the El Camino Real Widening project with Terri Dickerson of the California Department of Fish and Game (CDFG) and consultants from RECON and Planning Systems. The purpose of the meeting was to discuss CDFG's recommendations in a letter of response, dated October 22, 1998, to the City's circulation of a Mitigated Negative Declaration (MND) for the project. The participants walked the site, paying particular attention to the condition of the mulefat scrub on- site, which is in an area elevated above wetland areas and has been highly disturbed by transient worker encampments. As a result, Ms. Dickerson and the City agreed on the following: 1. The mulefat scrub is not associated with the streambed and, therefore, no Streambed Alteration Agreement with CDFG will be required. 2. Impacts to coastal sage scrub can be mitigated off-site at a ratio of 1:1 using credit from the City's Carlsbad Highlands mitigation bank. 3. Impacts to mulefat scrub can be mitigated off-site at a ratio of 2:1 by restoring additional area at the City's Cannon Road project mitigation site in Macario Canyon or by enhancing existing wetlands at a greater ratio. 4. To ensure there are no impacts to sensitive bird species if construction begins between February 15 and September 15, the City will conduct pre-construction surveys for active nests in suitable habitat within 250 feet of the construction zone. If active nests are found, no construction will occur within 200 feet of an active nest until the end of the breeding season (September 15). 5. Because off-site mitigation for mulefat scrub and coastal sage scrub will fully mitigate project impacts, restoration and monitoring of these communities on-site will not be required, other than standard City requirements for erosion control planting (or hydroseeding) with native species. 2075 Las Palmas Dr. • Carlsbad, CA 92009-1576 • (760) 438-1161 • FAX (760) 431-5769 November 18, 1998 MITIGATED NEGATIVE DECLARATION FOR THE EL CAMINO REAL WIDENING PROJECT Page 2 The City will include these measures in the mitigation monitoring and reporting program for the final MND.

Would it be simpler to amend Cannon Road West Streambed Alteration Agreement rather than process a new agreement? Anyway I have requested that RECON try to set up a meeting at the site to look at area and what City is proposing. I'd prefer to mitigate on-site because it enhances the Agua Hedionda Lagoon property. With the conditions to the mitigated neg, it appears agencies prefer we use Carlsbad Highlands. We actually did redesign the right turn lane as much as we safely could to avoid impacts. I know you are very busy. We would meet you out at the site at your convenience.

Page J From: Tom Held <theld@recon-us.com> To: GW-Domain.PO-LP(Showa) Date: 11/2/98 9:07AM Subject: El Camino Real Widening I talked to Dave Lawhead about the 10/22 letter. He had this to say about mitigation: Coastal Sage Scrub: Looks like the City has a choice. You can mitigate at the site: this would require 0.39 acre in the right-of-way and 0.31 acre adjacent to the row. In that case, there would have to be a restoration program and at least 3 years monitoring. Or you could mitigate by using credit off-site in a preserve area, like Carlsbad Highlands. In that case, the mitigation site would be 0.35 acre; no restoration plan and monitoring program would be required. The City will probably want to evaluate the relative costs of these options. Mule Fat Scrub: Need 0.64 acre of restoration. 0.31 can be done on-site (in the row). The rest would have to be offsite. Again, this could be adjacent. Dave suggested combining with the Cannon Road restoration. I don't know if any opportunity to do that is available. Dave also mentioned mitigation for the "Kelly Ranch Core Area," which he seemed to think is a possibility. I mentioned, with regard to sensitive bird species, that perhaps pre-construction surveys with a restriction on work within 200 feet of active nests might be preferable to a seasonal restriction on construction. Dave said that was a possibility. I also suggested that if Cannon Road was being constructed downstream at the same time, that might also be taken into account. Dave also suggested that, if the transfer of Kelly Ranch property has not occurred, it might be possible to mitigate mulefat off-site on that property (adjacent to ECR). I spoke to Terri Stewart about Kelly Ranch. She thought Dave might be right about mitigating there, but said I really ought to talk to Tim Dillingham and Terri Dickerson. She also suggested a meeting on-site to work it out. I have placed calls to Tim and (several times) to Julie Vanderwier. So far no answer on those.

The following materials were consulted as part of this review: The Negative Declaration (ND), inclusive of the Environmental Impact Assessment Form dated September 25,1998, the "Biological Technical Report for the El Camino Real Road Widening Project, Carlsbad, California" (RECON, September 18,1998), a letter report which discusses the results of a cultural resource survey for the El Camino Real widening project (RECON, June 4,1998), the "Noise Technical Report for the El Camino Real Road Widening Project, City of Carlsbad, California" (RECON, June 3,1998), and the HLP application dated December 16,1998. The project site is located along El Camino Real, between College Boulevard and Tamarack Avenue, just north of Evans Point. The existing road crosses Agua Hedionda Creek and includes the future intersection with Cannon Road . The project to be implemented is the "Reduced Impact Alternative" discussed hi the biological report which would widen the roadbed and the bridge crossing over Agua Hedionda Creek from 108 feet to 112 feet, construct an access road north of El Camino Real, and construct (or reconstruct) two energy dissipaters. Site elevation is approximately 40 feet above mean sea level (ASML); underlying soils are predominantly Salinas clay loam with areas of riverwash hi Agua Hedionda Creek.. Native or naturalized habitats which occur in the project area include the following: alkali marsh, mulefat scrub, Diegan coastal sage scrub, and non-native grassland. No sensitive plant or animal species were identified during the field surveys and it is unlikely that the project would affect any such species, including the coastal California gnatcatcher (Polioptila californica californica; gnatcatcher). Ms. Sherri Howard 2 Project implementation will result in both temporary and permanent impacts to Diegan coastal sage scrub (0.06 acre and 0.29 acre, respectively). Mitigation is proposed at a ratio of 1:1 and would be accomplished through the off-site acquisition of 0.35 acre of credit in the Carlsbad Highlands Mitigation Bank. In order to ensure that there are no adverse effects to nesting birds, the City will perform pre-construction surveys within 250 feet of the construction zone if vegetation removal and/or grading would occur between February 15 and and September 15. If active nests are identified within 200 feet of the construction zone, no construction will occur until after September 15. Based upon our review of the information submitted for this project, the resource agencies concur with the issuance of a 4(d) Special Rule permit for the proposed project as this habitat loss is consistent with the interim loss criteria established in the NCCP Conservation Guidelines listed below: • The habitat loss does not exceed the five percent guideline. While the City has now exhausted its five percent allocation, sufficient acreage was reserved by the City to accommodate the loss associated with the El Camino Real Widening project at its November 17,1998 City Council hearing. As such, sufficient acreage exists for the loss of this 0.35 acre of coastal sage scrub. • The habitat loss will not preclude connectivity between areas of high habitat values. The project does not lie within an identified core or linkage area and is not connected to any other natural habitat lands within the City. The project consists of the widening of an existing roadway. • The habitat loss will not preclude or prevent the preparation of the sub-regional NCCP. The loss of 0.35 acre of coastal sage scrub associated with the widening of El Camino Real would not preclude or prevent plan preparation as the acreage is small and the habitat value is low. • Habitat loss has been minimized and mitigated to the maximum extent practicable in accordance with Section 4.3 of the NCCP Guidelines by providing mitigation for impacts to coastal sage scrub at a ratio of 1:1 through the purchase of credits at the Carlsbad Highlands Mitigation Bank. • The habitat loss will not appreciably reduce the likelihood of survival and recovery of the coastal California gnatcatcher in the wild. While protocol-level surveys were not conducted for the gnatcatcher, the small and linear nature of the habitat to be affected makes it highly unlikely to provide nesting habitat for the gnatcatcher. At best, the site could provide habitat for one pair of birds, however, this loss would not preclude or appreciable reduce the likelihood of survival and recovery of the species. • The habitat loss is incidental to otherwise lawful activities. An Initial Study was prepared and ND adopted for this project in 1998. Identified impacts will be fully mitigated Ms. Sherri Howard 3 through the conditions which have been made part of the project description and as requirements of HLP issuance. As such, the Wildlife Agencies concur with the issuance of a HLP for the El Camino Real widening project. It should be noted that this permit only allows for the loss of 0.35 acre of coastal sage scrub in association with this project and expires within one year of Wildlife Agency concurrence. The acreage of coastal sage scrub impacts and preservation should be submitted to SANDAG for their use in the regional tracking system. Please provide us with copies of any notification regarding the expiration of this permit.

I. RECOMMENDATION That the Planning Commission ADOPT Planning Commission Resolution No. 4417. APPROVING a Mitigated Negative Declaration, and Mitigation Monitoring and Reporting Program, and ADOPT Planning Commission Resolution No. 4418 APPROVING CDP 98-47 based upon the findings and subject to the conditions contained therein. II. INTRODUCTION The improvement to El Camino Real is a City Capital Improvements Project. Because the road segment is located within the Coastal Zone a Coastal Development Permit is required. The area of construction is within 100 feet of a wetland and stream and is therefore in the Coastal Commission appeal area. III. PROJECT DESCRIPTION AND BACKGROUND The project is the improvement of El Camino Real for approximately 1,600 linear feet. The improvements include widening the existing bridge over Agua Hedionda Creek to accommodate sidewalks and intersection improvements at Cannon Road as shown on Exhibit A. North of the bridge, El Camino Real will be widened on the southbound side by 29 feet and by 17 feet on the northbound side. This widening will result in three travel lanes in either direction, a southbound right turn lane to Cannon Road, a southbound left turn lane to Cannon Road, bicycle lanes in either direction and sidewalks for an overall width of 138 feet. The additional width north of the intersection is for the right turn lane for southbound traffic. South of the intersection, the widening will result in a paved width for El Camino Real of 106 feet. The improvements will result in three travel lanes in either direction, a northbound left turn lane to Cannon Road, bicycle lanes in either direction and sidewalks. CDP 98-47 - El CAMINO K&\L WIDENING November 4, 1998 Page 2 IV. ANALYSIS Construction of the improvements to El Camino Real are consistent with the Circulation Element of the General Plan and is therefore consistent with the Local Coastal Program's designation for land use. Improvement of the right-of-way implements the goal of the circulation element for El Camino Real to be improved as a prime arterial. The road improvements will not obstruct views or otherwise damage the visual beauty of the coastal zone in that there are no significant visual resources associated with the area of disturbance. The project has been designed and a construction program which will suspend the additional bridge width from the existing bridge will completely avoid impacts to wetlands. There are neither agricultural activities nor geologic instability issues existing onsite. The project will implement the City's Master Drainage and Storm Water Quality Management Plan as well as the City's grading ordinance to avoid increased runoff and soil erosion. V. ENVIRONMENTAL REVIEW An analysis of the site was conducted and significant but mitigable impacts were identified. A Mitigated Negative Declaration was issued by the Planning Director and published for public comment dated September 25, 1998. Direct impacts were identified to disturbed coastal sage scrub and mule fat scrub. Applicable wildlife agency permits will be required. Although the mule fat scrub is a wetland indicator species, it was determined that it was not part of a wetland habitat because the required hydrology was not present. The bridge construction will be completed by suspending the improvements from the existing bridge with no impacts from construction to the area below the bridge. Therefore there will be no impacts to wetlands. The project is subject to mitigation measures as described in the Mitigated Negative Declaration and the Mitigation Monitoring and Reporting Program.

INTRODUCTION In accordance with your request, Ninyo & Moore has performed a hazardous materials evaluation of the project site located in Carlsbad, California (Figure 1). The purpose of this study was to evaluate hazardous materials conditions using available data and to provide a report, which will be utilized in the preparation of environmental impact documents. This report presents our findings and conclusions pertaining to the proposed El Camino Real Road Widening Project (Project). Subsurface exploration and laboratory testing of materials were not included in the scope of this evaluation. 2. SCOPE OF SERVICES RECON retained Ninyo & Moore to conduct a hazardous material evaluation for inclusion into an environmental impact report (EIR). The services were conducted in general accordance with Ninyo & Moore's proposal and scope of services dated January 13, 1998, and the subcontractor agreement between Ninyo & Moore and RECON. Ninyo & Moore's scope of services included the following tasks: • Reviewing readily available maps, reports, photographs, plans and other documents pertinent to hazardous materials issues for the site. The City of Carlsbad and RECON was requested to provide copies of, or access to pertinent maps, reports, photographs, plans and other docu- ments in their possession. • Performing a site reconnaissance, subject to site access, to visually identify areas of possibly contaminated surficial soil or water, improperly stored hazardous materials, possible sources of pesticides and polychlorinated biphenyls, and possible risks of contamination from activities at the sites and adjacent properties. • Reviewing available regulatory agency databases for the site and for properties located within a specified radius of the project site. Databases were used to identify locations of known haz- ardous waste sites, landfills, burn ash sites, leaking underground storage tanks, permitted facilities that utilize underground storage tanks and facilities that use, store, treat or dispose of hazardous materials. • Reviewing readily available historical aerial photographs. tyiny o RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 • Preparing this Hazardous Materials Evaluation report including an introduction, methodology, existing conditions, impact analysis, criteria of significance and mitigation measures supported by illustrations, references, agencies and individuals contacted, and a list of preparers. 3. SITE DESRIPTION AND EXISTING CONDITIONS The project area consists of an approximately 1,200-foot long section of El Camino Real (station 441+00 to 453+00), approximately 21A miles northwest of Palomar Airport Road in the city of Carlsbad (see Figure 1). El Camino Real is currently a four-lane roadway, with a paved section that is approximately 100-feet wide. In the project area, the roadway is located on a fill embank- ment that ranges from seven to ten feet in height above the surrounding floodplain of Agua Hedionda Creek. From Station 441+70 to Station 442+83, El Camino Real crosses Agua He- dionda Creek via a concrete bridge. The bridge is 113-feet long and 108 feet wide and is supported at two bents within the creek channel and two abutments. According to a report dated January 15, 1997, prepared by Agra Earth and Environmental, Inc., (AGRA) the foundation of the bridge consists of 14 Class XI piles at each abutment and bent. The AGRA report indicates that the piles may be either precast, prestressed concrete piles or step-taper steel shells (Raymond Step-Taper Piles) filled with concrete. The exposed portions of the piles at the bents are 16-inch diameter concrete columns. Elevations across the project area range from approximately 45.8 feet above mean sea level (MSL) near the center of the bridge to roughly 29 feet MSL within the Agua Hedionda Creek channel, west of the bridge. A topographic map is provided as Figure 2. Vegetation consists of moderate to dense native growth along the sides of the creek channel and within the floodplain west of the road. Agricultural land exists on the north side of El Camino Real, northwest of the bridge. A trailer park development exists on the north side of El Camino Real, northeast of the bridge. Existing conditions are further discussed in Section 7.0. RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 4. PROJECT DESCRIPTION The proposed project will consist of the widening of El Camino Real from approximately Station 441+00 to Station 453+00 (roughly 1,200 feet). The widening includes the addition of one lane on each side, widening the existing bridge over Aqua Hedionda Creek by two feet on each side, and the addition of a right-turn lane from southbound El Camino Real to (future) westbound Can- non Road. The proposed Cannon Road will cross El Camino Real approximately 75 feet north of the existing bridge, then will cross Aqua Hedionda Creek via a proposed bridge to be located ap- proximately 150 feet southwest of the existing El Camino Real bridge. 5. ENVIRONMENTAL SETTING The following sections include discussions of the topographic, geologic, soil and hydrogeologic conditions; a review of available published documents; and presents the findings of our visual site reconnaissance of the property and adjacent areas. 5.1. Topographic Conditions In general, the project is located in near the center of Agua Hedionda Valley, and the area surrounding the project consists of moderate to steeply ascending hills. Surface drainage in the valley is towards the southwest into the nearby Agua Hedionda Lagoon. The approximate elevation of the current road is 40 to 45 feet MSL. A topographic map is presented as Figure 2. 5.2. Geologic Conditions The project area is situated in the western portion of the Peninsular Ranges geomorphic province of southern California. 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 tip of Baja California (Norris and Webb, 1990). The geomorphic province varies in width from 30 to 100 miles, most of which is character- ized by northwest trending mountain ranges separated by subparallel fault zones. In general, RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 the Peninsular Ranges are underlain by Jurassic-age metavolcanic and metasedimentary rocks and by Cretaceous-age igneous rocks of the southern California batholith. The westernmost portion of the province in San Diego County, in which the site is located, generally consists of Upper Cretaceous-, Tertiary-, and Quaternary-age sedimentary rocks. The Peninsular Ranges are traversed by several major active faults (Figure 3, Fault Location Map). The Whittier-Elsinore, San Jacinto, and the San Andreas faults are major active fault systems located northeast of the site and the Agua Blanca-Coronado Bank and San Clemente faults are active faults located to the west-southwest. The Rose Canyon fault zone is also a major fault system, located offshore of Carlsbad, portions of which have recently been recog- nized as active by the State of California. Major tectonic activity associated with these and other faults within this regional tectonic framework is right-lateral strike-slip movement. These faults, as well as other faults in the region, have the potential for generating strong ground motions at the project site. 5.3. Site Geology Based on our literature review, including published geologic maps and available geotechnical reports, the project is underlain generally by artificial fill, alluvium, and formational materials of the Santiago Formation. A brief description of these units, as described in the cited litera- ture, or as observed at the project area, is presented below. 5.3.1. Artificial Fill Previous construction along and adjacent to El Camino Real has resulted in the place- ment of artificial fill. Based on review of previous geotechnical reports and topographic maps, these fill soils are expected to be up to roughly 10 feet deep along the existing roadway. These soils consist generally of clayey sands and silty sands. In addition to these soils, riprap composed of boulder-sized rocks locally line the abutments of the ex- isting bridge. tyinyo RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 5.3.2. Alluvium Recent alluvial deposits underlie the fill soils. The alluvium was within the floodplain of Agua Hedionda Creek. Based on the previous geotechnical reports, the alluvium is de- scribed as soft to stiff silty clay and loose to medium dense silty sand. The alluvium is expected to be greater than 100-feet deep in the project vicinity. 5.3.3. Santiago Formation Materials of the Eocene-age Santiago Formation underlie the alluvium in the project area. The Santiago Formation is described as very dense, silty sandstone and interbedded hard claystone. A more detailed analysis of geologic conditions, including faults, liquefaction, landslides, and other geologic hazards are discussed under a separate report prepared by Ninyo & Moore dated June 4, 1998. 5.4. Groundwater Conditions Based on our site reconnaissance and review of previous geotechnical reports, the depth to groundwater is expected to occur at a depth of approximately 10 to 15 feet below the exist- ing road grade. The depth to groundwater may be at or near the ground surface within Agua Hedionda Creek. At the time of our site visit, on May 15, 1998, there was a moderate flow of water within Agua Hedionda Creek. The depth to groundwater at the site may fluctuate with seasonal variations and perched conditions may be locally present. 6.

Planning and Zoning Information The City of Carlsbad Department of Planning and Zoning was contacted to inquire whether or not the City of Carlsbad has any specific criteria of significance for hazardous materials evaluations as part of an EIR. The City does not have any specific criteria of significance for hazardous materials evaluations and defers to the California Environmental Quality Act (CEQA) guidelines. ty/nyo RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 6.5. Summary of Historical Site Use Ninyo & Moore reviewed historical documents, including aerial photographs, to evaluate prior features that may indicate structures, facilities or activities which might reflect the use, storage or disposal of hazardous substances at the site. Our aerial photograph review indi- cated that El Camino Real road was constructed prior to 1928. Past land use in the vicinity of the site has been agricultural and residential. No documentation of commercial or industrial land use adjacent to the site was found during the evaluation of the history of the site. 7. SITE RECONNAISSANCE On May 15, 1998, a site reconnaissance was conducted by a representative of Ninyo & Moore, and involved a walking tour of the site and visual observations of adjoining properties. Photo- graphs taken during the reconnaissance are on file at Ninyo & Moore and are available for review upon request. 7.1. Chemical Storage/Hazardous Waste Storage At the time of the reconnaissance, warning signs and surface mark out for buried petroleum pipelines and a natural gas pipeline were observed. Other areas of chemical or hazardous waste storage were not observed on immediately adjacent to the site. Minor amounts of trash were observed along each side of the road. 7.1.1. Liquid Petroleum Pipelines Two petroleum pipelines owned and operated by Santa Fe Pacific Pipelines (SFPP) are located on the subject site. Ninyo & Moore contacted Mr. Don Quinn of the Kinder Morgan Energy Partners, L.P., an operating partner with SFPP, L.P., to inquire about the history, construction type, environmental status, and location of the two pipelines. SFPP, L.P., operates and/or maintains one active 16-inch diameter high pressure refined petroleum pipeline and an idle 10-inch diameter pipeline which is presently under a nitro- gen charge. The pipelines are constructed of single wall welded steel, coated and under RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 cathodic protection. The 10-inch diameter pipeline was constructed in 1962 and the 16- inch diameter pipeline was constructed 1985. A hydrostatic pressure test performed on each of the pipelines at the time of construction prior to placing them in service. The 16-inch diameter pipeline was also internally in- spected in 1996 in accordance with the provisions of the "California Pipeline Safety Act" as approved by the California State Fire Marshall. The active pipeline currently has a leak detection system that is based on the computer- ized surveillance of the volumetric line balance, pressure deviation and flow deviation. Mr. Quinn indicated that plans have been formulated to install a new monitoring system to enhance the leak detection capabilities by the end of 1999. According to Mr. Quinn, historical information does not indicate that a spill or release of product has occurred in the subject area. Mr. Quinn supplied Ninyo & Moore with maps showing the location of the 10- and 16- inch diameter pipelines. The 10-inch diameter pipeline is generally located on the south- ern portion of El Camino Real, and the pipeline crosses south of the bridge that crosses Agua Hedionda Creek. The 16-inch diameter pipeline is generally located in the middle portion of El Camino Real, and the pipeline traverses through the approximate center of the bridge. The request and response regarding the petroleum pipelines is included in Appendix A. 7.1.2. Natural Gas Pipeline A San Diego Gas & Electric (SDG&E) high pressure natural gas line is located on the subject site. A request was made to SDG&E regarding the history, construction type, environmental status, and location of the pipeline. A response has not been received from SDG&E at the time of this report. RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 7.2. Polychlorinated Biphenyls (PCBs) Three pole mounted electrical transformers were observed on one pole near the southwest corner of the intersection of El Camino Real and Hidden Valley Road. The electrical trans- formers are owned and operated by SDG&E. The transformer's locations and identification numbers were given to SDG&E, and a request was made to obtain the date of installation and whether or not the transformer's fluid contained PCBs. According to an SDG&E representa- tive, based on routine random testing performed by SDG&E, it is unlikely that the transformers contain PCBs. No visible leakage from the transformers or soil staining was ob- served in the area of these transformers. 7.3. Subsurface Structures and Buried Utilities Evidence of substructures such as utility vaults, sewer manholes, water meters, and other ac- cessways were observed on site. Available plans show subsurface water lines, sewer lines, electrical lines, storm drain lines, a natural gas pipeline, and liquid petroleum pipelines are lo- cated on or near the site. 7.4. Surface Staining Areas of significant surficial staining were not observed during the site reconnaissance. 7.5. Wells Water wells were not observed on or immediately adjacent to the subject site. The U.S.G.S. San Luis Rey Quadrangle Map shows a well located approximately one mile to the north of the site. 8.

SIGNIFICANCE OF IMPACTS The City of Carlsbad Department of Planning does not have a criteria for significance determina- tion guideline. Criteria for significance determination was obtained from the guidelines set forth in the document entitled "Significance Determination Guidelines Under the California Environmental Quality Act" prepared by the City of San Diego Planning Department, Environmental Analysis Section, dated January 1991 (revised January 1994). The following criteria were compared with each of the findings of this study to determine their impact significance to the proposed redevel- opment project: • All uses proposing the handling, storage, and treatment of hazardous materials (i.e., a hazard- ous waste treatment center). • Sites on or near known contamination sources. • All cases of dewatering. 17 RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 • Demolition of old commercial, industrial and residential structures (i.e., asbestos and other hazardous materials). • Removal of underground fuel tanks. • Residential, day care, social agencies, and schools in industrial areas. 11. ENVIRONMENTAL IMPACTS The following environmental impact sites, as identified in this study, were compared with the sig- nificance criteria as outlined in Section 10: • No environmental impacts relating to hazardous materials are anticipated for the proposed project. 12. MITIGATION MEASURES In accordance with the significance determination criteria discussed in Section 10, the following mitigation measures are recommended: • A hazardous waste treatment center is not proposed for the redevelopment, therefore, mitiga- tion measures regarding such a facility are not required. If hazardous materials are proposed to be temporarily stored on the site for construction pur- poses, then they should be stored and used in accordance with all applicable federal, state and local laws and regulations. • The project site is not located on or near an area of known soil or groundwater contamination, therefore, mitigation measures regarding known soil or groundwater contamination are not required. However, in order to prepare for the possibility of encountering unknown soil or groundwa- ter contamination during construction, a contingency plan should be prepared to address contractor procedures for such an event to minimize the potential for costly construction de- lays. • Although it is not anticipated, if construction dewatering is required for the project, the efflu- ent must meet discharge requirements for National Pollution Discharge Elimination System (NPDES) permitting and/or City of Carlsbad sewer system discharge. • Demolition of old industrial, commercial, or residential structures is not proposed for the road widening project, therefore, mitigation measures are not required. 18 RECON June 4, 1998 El Camino Real Road Widening Project, Carlsbad Project No. 103635-02 Underground storage tank removal is not proposed for the project; therefore, mitigation measures regarding these activities are not required. It is our understanding that the natural gas and petroleum pipelines will not be disturbed or relocated during the road widening proj- ect. Extreme caution is warranted when working near the pipelines. The location of the nearest shut off valves for the pipelines should be located and made accessible during the con- struction phase of the project. Residential, day care, social agencies, and schools are not proposed for the project; therefore, mitigation measures regarding these facilities are not required. 13.

I am working for Recon, Inc. and the City of Carlsbad. The site is approximately 1500 feet long and is located near the intersection of El Camino Real and Hidden Valley Road near Agua Hedionda Creek (see attached site map). During the site reconnaissance two Santa fe Pacific pipelines were marked out with paint on or near the road way. Potholes were observed on the south side of El Camino Real. I am requesting the following information regarding the pipelines in the area of the site: 1) Date of installation of the pipelines, 2) location and approximate depths of the pipelines, 3) pipe diameter and construction type, 4) leak detection, cathodic protection, hydrostatic pressure test or pipeline integrity information regarding the pipelines, 5) type of products transported in pipelines, and 5) knowledge of leaks, spills or releases in the general area of the road widening project. Thank you for your time.

SFPP, L.P.'s operates and/or maintains one active 16-inch high pressure refined petroleum products pipeline and an idle 10-inch pipeline (presently under a nitrogen charge) within the limits of the subject inquiry. The pipelines are of welded steel construction, coated and under cathodic protection. The 16-inch was installed in 1985 and the 10-inch was installed in 1962. Enclosed for your information is one (1) copy each of Drawing LS-126, sheets 75 & 76 and LS-122, sheet 41 depicting the general alignment of these pipelines within the subject area. A hydrostatic pressure test was performed on both pipelines at time of construction before placing them in service. The 16-inch pipeline was also internally inspected in 1996 in accordance with provisions of the "California Pipeline Safety Act" as approved by the California State fire Marshall. The current leak detection system is based on the computerized surveillance of volumetric line balance, pressure deviation and flow deviation. Plans are presently being formulated to have in operation by the end of 1999, a new SCADA system that will enhance these leak detection capabilities. 1100 Town & Country Road Orange, California 92868 714/560-4600 714/560-4601 Fax Peter David Clark May 26, 1998 Page 2 ** Historical information does not indicate that a spill or release of product was experienced in the m subject area. ^ If you have any questions concerning this matter I can be reached at (714) 560-4940 and please ** include the above file reference number on all correspondence.

JuneS, 1998 Mr. Peter Clark Ninyo & Moore Environmental Services 10225 Barnes Canyon Road. #A112 San Diego, Calif. 92121 Dear Mr. Clark; This letter responds to your inquiry regarding any SDG&E-owned electric transformers located along the SOUTH-SIDE OF EL CAMINO REAL, AT THE INTERSECTION OF HIDDEN VALLEY ROAD & EL CAMINO REAL, CARLSBAD, CALIFORNIA. . Our records indicate that there are presently three transformers in service at the above location: SDG&E Station #783-435. SDG&E has never specified PCB transformers for its electric distribution service. Although only mineral oil transformers were purchased, some older (pre-1980) mineral oil transformers were inadvertantly contaminated with PCB's by the manufacturer. You are virtually assured that there are no PCB's in these mineral oil transformers. The only way to know with certainty is by testing. SDG&E is responsible for ensuring that its transformers comply with EPA regulations governing PCB's, however, EPA regulations do not require the testing of individual mineral oil transformers. Therefore, should you wish that done, there will be a charge if the unit is confirmed to be non-PCB, and a electric service interruption may be necessary. Please call me at (619) 654-8340 if you need additional information. Sincerely, Hal Larsen Cust. Records Coord.

The agency release date for NPL was January, 1998. The National Priorities List (NPL) is the EPA's database of uncontrolled or abandoned hazardous waste sites identified for priority remedial actions under the Superfund program. A site must meet or surpass a predetermined hazard ranking system score, be chosen as a state's top priority site, or meet three specific criteria set jointly by the US Dept of Health and Human Services and the US EPA in order to become an NPL site. SPL VISTA conducts a database search to identify all sites within 1.25 mile of your SRC#: 4544 property. The agency release date for Calsites Database: Annual Workplan Sites was January, 1998. This database is provided by the Cal. Environmental Protection Agency, Dept. of Toxic Substances Control. The agency may be contacted at: 916-323-3400. SCL VISTA conducts a database search to identify all sites within 1.25 mile of your SRC#: 4543 property. The agency release date for Calsites Database: All Sites except Annual Workplan Sites (incl. ASPIS) was January, 1998. This database is provided by the Department of Toxic Substances Control. The agency may be contacted at: . The CalSites database includes both known and potential sites. Two- thirds of these sites have been classified, based on available information, as needing "No Further Action" (NFA) by the Department of Toxic Substances Control. The remaining sites are in various stages of review and remediation to determine if a problem exists at the site. Several hundred sites have been remediated and are considered certified. Some of these sites may be in long term operation and maintenance. CORRACTS VISTA conducts a database search to identify all sites within 1.25 mile of your SRC#: 4244 property. The agency release date for HWDMS/RCRIS was October, 1997. The EPA maintains this database of RCRA facilities which are undergoing "corrective action". A "corrective action order" is issued pursuant to RCRA Section 3008 (h) when there has been a release of hazardous waste or constituents into the environment from a RCRA facility. Corrective actions may be required beyond the facility's boundary and can be required regardless of when the release occurred, even if it predates RCRA.

Temporary impacts would be 0.27 acre of disturbed coastal sage scrub, 0.01 acre of alkali marsh, and 0.22 acre of disturbed mule fat scrub. No sensitive plant or animal species were observed within the project boundaries. An alternative to the project design has been proposed to reduce the length of the southbound right-turn lane and is acceptable to the City. This alternative would eliminate the impact to alkali marsh and reduce impacts to disturbed coastal sage scrub to 0.35 acre. Under this alternative, the project would result hi no impacts to alkali marsh, the same impacts to disturbed mule fat scrub as the proposed project, and 0.06 acre of temporary impacts and 0.29 acre of permanent impacts to disturbed coastal sage scrub. Mitigation for impacts to disturbed coastal sage scrub will be accomplished through the restoration and enhancement of temporarily impacted areas and revegetation of newly manufactured slopes for a total of 0.39 acre of restored Diegan coastal sage scrub. Significant permanent impacts to 0.13 acre of alkali marsh and disturbed mule fat scrub will be mitigated by restoration of 0.09 acre of eucalyptus woodland to mule fat scrub and by the restoration of 0.04 acre off-site to 0.01 acre of mule fat scrub and 0.03 acre of alkali marsh. Significant temporary impacts to 0.23 acre of these types of habitat will be mitigated by restoration of the area impacted to the original condition, or to a higher quality habitat. For the proposed project, impacts to alkali marsh would require a Section 404 permit from the U.S. Army Corps of Engineers (USAGE). A Section 1601 agreement with the California Department of Fish and Game (CDFG) would be required for impacts to alkali marsh and disturbed mule fat scrub. The disturbed mule fat scrub does not meet USAGE criteria for jurisdictional waters or wetlands. The alternative with reduced impacts may require a Section 1601 agreement with CDFG. Introduction The El Camino Real road widening site is located in the city of Carlsbad, California (Figure 1), between the intersections of El Camino Real with Tamarack Avenue and College Boulevard (Figure 2). The proposed project includes the widening of the roadbed and the bridge crossing over Agua Hedionda Creek, the construction of an access road north of El Camino Real, and the construction and/or reconstruction of three energy PROJECT LOCATION AGUA HEDIONDA LAGOON 4 2 MILES 0 FIGURE 1 Regional Location of the Project ., 'Water : (\ 7 Tank » PROJECT LOCATION Smlorosa I '.Country Club, , H Map Source: U.S.G.S. 7.5 minute topographic map, jijlji; San Luis Rey quadrangle 200 FEET 0 FIGURE 2 Project Location dissipators on each side of the road. The reduced-impact alternative would eliminate reconstruction of one of these energy dissipators. The site is bounded by residential development and a nursery to the north, a private residence to the northwest, and a ranch to the south. This report provides biological data and background information required for environmental analysis by the California Environmental Quality Act (CEQA). Survey Methods A biological resources survey was conducted by RECON biologist Wendy Loeffler on May 7,1998 from 10:00 A.M. to 3:00 P.M. and May 11,1998 from 7:00 to 9:00 A.M. The area surveyed included a corridor of habitat that was 25 feet from the pavement on both sides of El Camino Real for a length of approximately 1,650 feet. In addition, adjacent areas along the road that will be modified for a haul road and storm water runoff were also surveyed. The surveyed area is larger than the actual limits of construction and thus larger than the area of impact. Animal species observed directly or detected from calls, tracks, scat, nests, or other sign were noted. All plant species observed on-site were also noted, and plants that could not be identified in the field were identified later using taxonomic keys. Limitations to the compilation of a comprehensive floral checklist were imposed by seasonal factors, such as blooming period and emergence of some annual species. In addition, nocturnal animals were not observed directly as both surveys were performed during the day. Floral nomenclature follows Hickman (1993) for common plants and Skinner and Pavlik (1994) for sensitive species. Plant community classifications follow the California Natural Diversity Data Base (NDDB) (Holland 1986). Zoological nomenclature for birds is in accordance with the American Ornithologists' Union Checklist (1983 and supplements); for mammals, Jones et al. (1982); and for amphibians and reptiles, Collins (1997). Assessments of the sensitivity of species and habitats are based primarily on Skinner and Pavlik (1994), State of California (1997a, 1997b, 1998), U.S. Fish and Wildlife Service (USFWS 1996), and Holland (1986). Existing Conditions A. Topography and Soils Elevation of the site is approximately 40 feet above mean sea level (U.S. Geological Survey 1968). Soils on the site consist of Salinas clay loam for the majority of the site and riverwash for Agua Hedionda Creek. Salinas clay loam tends to be a well-drained soil and is formed from sediments washed from a variety of other soil types. Riverwash soils are typically sandy, gravelly, or cobbly with sparse vegetation consisting of scattered sycamore or coast live oak trees and other shrubs or forbs occurring in patches (U.S. Department of Agriculture 1973). B. Botany Eleven vegetation communities were identified on the 11.9-acre survey area: alkali marsh, southern willow scrub, mule fat scrub, disturbed mule fat scrub, freshwater marsh, disturbed Diegan coastal sage scrub, non-native grassland, eucalyptus woodland, horticultural, open/disturbed, and developed. A vegetation map was recently prepared for the Kelly Ranch property, which is located on the south side of El Camino Real (Planning Systems 1997). These data were incorporated into the current vegetation map insofar as the existing conditions were determined to be the same. One area identified as disturbed mule fat scrub on the previous vegetation map has been brushed and was consequently identified as open/disturbed during the current surveys. Figure 3 illustrates the locations of the plant communities on-site on an approximately 1500-scale base map. A total of 66 plant species were identified within the surveyed area (Table 1). Of this total, 33 (50 percent) are species native to southern California and 33 (50 percent) are introduced species. 1. Alkali Marsh The approximately 0.10 acre of alkali marsh is located on the southeast corner of the surveyed area and is located within an area revegetated as partial mitigation for impacts incurred from the construction of the adjacent Evans Point housing development (RECON 1994a). The dominant ground cover consists of saltgrass (Distichlis spicatd) and jaumea (Jaumea carnosa), with pickleweed (Salicornia sp.) as a subdominant species. Patches of other native species, such as Mexican rush (Juncus mexicanus), curly dock (Rumex crispus), and yerba mansa (Anemopsis californica), are also present. This habitat is immediately adjacent and contiguous with a small, inundated estuarine area that supports a number of native floral and faunal species. 2. Southern Willow Scrub Southern willow scrub was identified on approximately 1.12 acres of the surveyed area and along both banks of Agua Hedionda Creek on the south side of the El Camino Real bridge crossing. This habitat is dominated by mature arroyo willow (Salix lasiolepis) with a sparse understory of water cress (Rorippa nasturtium-aquaticum), fennel (Foeniculum vulgare), mustard (Brassica sp.), and bristly ox-tongue (Picris echioides).

Disturbed Diegan Coastal Sage Scrub Approximately 0.83 acre of disturbed Diegan coastal sage scrub extends almost the entire length of the surveyed area and is located adjacent to El Camino Real on the southern side of the road. The community contains several of the key components of Diegan coastal sage scrub; however, the habitat is dominated by non-native, weedy species. The portion of this habitat located at the southeastern corner of the study area was also revegetated as partial mitigation for impacts from the construction of the Evans Point development (RECON 1994a). The dominant species include mustard, white sweet clover (Melilotus alba), yellow sweet clover (M. officianalis), wild oat (Avena sp.), and bristly ox-tongue, all non-native species. Approximately 30 percent of the habitat includes native species characteristic of this community, such as California sagebrush (Artemisia californica}, coast goldenbush (Isocoma menzesii), common encelia (Encelia californicd), and golden-yarrow (Eriophyllum confertifolium). 4. Mule Fat Scrub Mule fat scrub was identified on approximately 0.13 acre of the surveyed area and was also planted as a component of the revegetation plan for the Evans Point development (RECON 1994a). The two dominant plants are mule fat (Baccharis salicifolid) and narrow-leaved willow (Salix exigua). Understory species identified include bristly ox- tongue, curly dock, Mexican rush, bulrush (Scirpus sp.), nutsedge (Cyperus sp.), annual beard grass (Polypogon monspeliensis), desert wild grape (Vitis girdiand), fennel, and celery (Apium graveolens). 5. Disturbed Mule Fat Scrub This habitat was identified on approximately 0.32 acre of the surveyed area and is located on the south side of El Camino Real. This habitat contains many of the dominant species characteristic of mule fat scrub; however, these areas also include a larger percent cover of non-native, weedy species. This area, and adjacent areas off-site, are also heavily used by migrant workers, whose camps are pervasive hi the area and contribute to the disturbance of the habitat. 6. Freshwater Marsh The area designated as freshwater marsh encompasses 0.48 acre of the Agua Hedionda Creek channel and associated vegetated banks. This habitat is located on both the north and south side of El Camino Real where the creek flows under the roadbed. The creek channel is fairly shallow and unvegetated with associated riparian banks. The south side of the road is more densely vegetated and is dominated by common horsetail (Equisetum arvense). Water cress, fennel, giant reed (Arundo donax), willow weed (Polygonum lapathifolium), and cattail (Typha sp.) are also present. The banks on the north side of El Camino Real are more sparsely vegetated and include brass buttons (Cotula 10 coronopifolia), English plantain (Plantago lanceolatd), water cress, and Bermuda grass (Cynadon dactylon). 7. Non-Native Grassland A small area of non-native grassland, approximately 0.31 acre in size, is located on the north side of El Camino Real on the northwest end of the surveyed area. This habitat is dominated by wild oat, foxtail chess (Bromus madritensis ssp. rubens), fennel, mustard, sweet clover, and cheeseweed (Malva parviflorwri). 8. Eucalyptus Woodland Approximately 0.18 acre of eucalyptus woodland was identified on the south side of El Camino Real. The habitat is dominated by large, mature eucalyptus trees (Eucalyptus sp.) with a sparse understory. 9. Horticultural Approximately 0.12 acre of common landscape/horticultural species is planted adjacent to the roadbed on the north and south side of El Camino Real to the east of Agua Hedionda Creek. The plants identified include African daisy (Gazania sp.), eucalyptus, pine (Pinus sp.), firethora (Pyracantha sp.), and Bermuda grass. 10. Open/Disturbed The approximately 3.92 acres of open/disturbed community on the site is primarily bare ground with ruderal areas dominated by non-native species and an occasional native shrub. The areas designated as open/disturbed include the strips of bare ground located adjacent to El Camino Real on both sides, the area recently brushed, and a portion of a palm tree nursery located on the north side of the road. All areas identified as open/disturbed are located on the west side of Agua Hedionda Creek. The most common plants observed include bristly ox-tongue, sow thistle (Sonchus spp.), wild oat (Avena sp.), filaree (Erodium sp.), cheeseweed, scarlet pimpernel (Anagallis arvensis), and Bermuda grass. The brushed area discussed above also includes a sparse regrowth of mule fat and coast goldenbush. 11. Developed El Camino Real and an access road for the Kelly Ranch property account for approximately 4.40 acres of developed area. This area includes the asphalt roadways, concrete sidewalks, and concrete median on El Camino Real. 11 C. Zoology The site is overall of moderate value for wildlife species. The southern willow scrub on- site does provide potential habitat for the least Bell's vireo and southwestern willow flycatcher. A complete list of the wildlife species detected is provided in Table 2. Sensitive species potentially occurring on-site are discussed in the Sensitive Biological Resources section. 1. Amphibians No amphibians were observed on-site. Species expected to commonly occur on-site include Pacific treefrog (Hyla regilla). 2. Reptiles Several male western fence lizards (Sceloporus accidentally) were observed on-site. Other reptiles expected to occur include side-blotched lizard (Uta stansburiana) and San Diego gopher snake (Pituophis melanoleucus). 3. Birds Bird species observed on-site include Anna's hummingbird (Calypte anna), black phoebe (Sayornis nigricans), song sparrow (Melospiza melodia), and American crow (Corvus brachyrhynchos). Several bird species, commonly found hi wetland and estuarine habitats, were observed foraging hi the adjacent estuarine area and include great blue heron (Ardea herodias herodias), great egret (Ardea alba), Forster's tern (Sterna forsteri), and black tern (Chilodonias niger surinamensis). As these species were not observed within the designated survey area, they are recorded hi Table 2 as flying overhead. 4. Mammals Cottontail rabbits (Sylvilagus audubonii) were observed on-site, as was the carcass of a coyote (Cam's latrans). Other mammals expected to use the site include California ground squirrel (Spermophilus beecheyi) and striped skunk (Mephitis mephitis). D. Sensitive Biological Resources For purposes of this report, species will be considered to be sensitive if they are (1) listed by state or federal agencies as threatened or endangered or are proposed for listing; (2) on List IB (considered endangered throughout its range) or List 2 (considered endangered hi California but more common elsewhere) of the California Native Plant Society's (CNPS) Inventory of Rare and Endangered Vascular Plants of California (Skinner and Pavlik 12 TABLE 2 WILDLIFE SPECIES OBSERVED/DETECTED ON THE EL CAMINO REAL ROAD WIDENING SITE Common Name Scientific Name Occupied Habitat Status Evidence of Occurrence Reptiles (Nomenclature from Collins 1997) Western fence lizard Sceloporus occidentalis Birds (Nomenclature from American Ornithologists' Union) Great blue heron Great egret Snowy egret Mallard Killdeer Forster's tern Black tem Mourning dove Anna's hummingbird Black phoebe Western scrub-jay Yellow-breasted chat Song sparrow Red-winged blackbird Ardea herodias herodias Ardea alba Egretta thula thula Anas platyrhynchos platyrhynchos Charadrius vociferus vociferus Sterna forsteri Chlidonias niger surinamensis Zenaida macroura marginella Calypte anna Sayomis nigricans semiatra Aphelocoma califomica Icteria virens auricollis Melospiza melodia Agelaius phoeniceus i (Nomenclature from Jones et al. 1982) Cottontail rabbit Coyote Sylvilagus audubonii Canis latrans DCSS F F F F O F F DCSS.EUC DCSS,MF FM.SWS EUC AM MF,AM F DCSS,O,EUC O SDC,* SDC,* SDC,* CSC CSC.SDC O O O O O V O O O O O O V O O c,oc Habitats AM = DCSS = DMF = EUC = Alkali meadow Disturbed coastal sage scrub Disturbed mule fat scrub Eucalyptus woodland F = Flying overhead FM = Freshwater marsh MF = Mule fat scrub O = Open places, waste places, roadsides, burns, etc. Status CFP CSC SDC = California fully protected species = California Department of Fish and Game species of special concern = City of San Diego Resource Protection Ordinance "Sensitive Species" = Taxa listed with an asterisk fall into one or more of the following categories: • Taxa considered endangered or rare under Section 15380(d) of CEQA guidelines • Taxa that are biologically rare, very restricted in distribution, or declining throughout their range • Population(s) in California that may be peripheral to the major portion of a taxon's range, but which are threatened with extirpation within California • Taxa closely associated with a habitat that is declining in California at an alarming rate (e.g., wetlands, riparian, old growth forests, desert aquatic systems, native grasslands) Evidence of Occurrence V = Vocalization O = Observed C = Carcass/remains 1994); or (3) considered rare, endangered, or threatened by the NDDB (State of California 1994, 1997a) or local conservation organizations or specialists. Noteworthy plant species are considered to be those which are on List 3 (more information about the plant's distribution and rarity needed) and List 4 (plants of limited distribution) of the CNPS Inventory. Sensitive habitat types are those identified by the California Natural Diversity Data Base (Holland 1986) or are considered sensitive by other resource agencies. Assessments for the potential occurrence of sensitive or noteworthy species are based upon known ranges and habitat preferences for the species (Skinner and Pavlik 1994; Reiser 1994), species occurrence records from the NDDB, and species occurrence records from other sites hi the vicinity of the project site. 1. Sensitive Plants No sensitive plants were observed on-site. Several other sensitive plant species are known to occur in the vicinity of the project site and are considered as potentially occurring on-site. A botanical survey was conducted to search for sensitive plant species. Table 3 summarizes the status, habitats, and results of the botanical survey for each of these potentially occurring species. Many of these species, such as shrubs or large cactus, would have been easily observed on the site during the sensitive plant survey. Others were either within their blooming period during the survey or are easily identifiable through vegetative characters. Thus, with the fact that they were not observed, they are considered to have a low potential for occurrence. 2. Sensitive Wildlife No wildlife species considered sensitive by resource agencies were observed on the site during the survey; however, several birds that are afforded some protection by resource agencies were heard or observed in the alkali marsh and in the estuarine area adjacent to the alkali marsh on-site. The yellow-breasted chat (Icteria virens), a California species of special concern, was heard within several clumps of vegetation just outside of the survey area. This species has been identified previously on the adjacent Kelly Ranch property and there is a potential for this species to nest on-site (Planning Systems 1997). Several seabirds were observed foraging within the estuarine area on-site. These include the black tern, Forster's tern, snowy egret (Egretta thula thula), great egret, and great blue heron; however, there is no evidence or expectation of nesting colonies or rookeries, which are the protected resource for each of these species. Several sensitive wildlife species have been identified in the vicinity of the project site, such as least Bell's vireo (Vireo bellii pusillus), Belding's savannah sparrow (Passerculus sandwichensis beldingi), coastal California gnatcatcher (Polioptila californica calif arnica), and orange-throated whiptail (Cnemidophorus hyperythrus) (Planning Systems 1997). In addition, the southern willow scrub community on the Kelly Ranch property has been identified as 14 TABLE 3 SENSITIVE PLANT SPECIES WITH THE POTENTIAL FOR OCCURRENCE ON THE EL CAMINO REAL ROAD WIDENING SITE Species State/Federal CNPS CNPS Status List Code Typical Habitat/Comments Acanthomintha ilicifolia San Diego thornmint Adolphia californica California adolphia Artemisia palmeri San Diego sagewort Brodiaea filifolia Thread-leaved brodiaea Chorizanthe orcuttiana Orcutt's spineflower Cordylanthus orcuttianus Orcutt's bird's-beak CE/PE IB 2-3-2 Chaparral, coastal sage scrub, valley and foothill grassland/clay soils; not observed on-site -/- 2 1-2-1 Chaparral, coastal scrub/clay soils; not observed on-site -/- 2 2-2-1 Coastal sage scrub, riparian scrub/sandy; not observed on-site CE/PT IB 3-3-3 Coastal scrub, cismontane woodland, valley and foothill grassland, vernal pool clay; not observed on-site CE/PE IB 3-3-3 Coastal sage scrub; Del Mar to Point Loma, San Diego County; not observed on-site -/- 2 3-3-1 Coastal sage scrub; not observed on-site Dichondra occidentalis —I— Western dichondra Dudley a variegata -I- IB Variegated dudleya Euphorbia misera —I— 2 Cliff spurge Ferocactus \\ridescens -I- 2 Coast barrel cactus Harpagonella palmeri var. palmeri -I- 2 Palmer's grappling hook Hemizonia parryi ssp. australis -I- IB (-Hemizonia australis) Southern tarplant 1-2-1 Chaparral, cismontane woodland, coastal sage scrub, valley and foothill grassland; not observed on-site 1-2-2 Chaparral, coastal sage scrub; not observed on-site 2-2-1 Coastal sage scrub/rocky; no suitable habitat 1-3-1 Chaparral, coastal sage scrub, valley and foothill grassland; not observed on-site 1-2-1 Chaparral, coastal sage scrub, valley and foothill grassland; not observed on-site 3-3-2 Valley and foothill grassland; not observed on-site TABLE 3 SENSITIVE PLANT SPECIES WITH THE POTENTIAL FOR OCCURRENCE ON THE EL CAMINO REAL ROAD WIDENING SITE (continued) Species State/Federal CNPS Status List CNPS Code Typical Habitat/Comments Juncus acutus ssp. leopoldii (=Juncus acutus ssp. sphaerocarpus) Spiny rush Muilla clevelandii San Diego goldenstar IB 1-2-1 Coastal dunes (mesic), meadows (alkaline), coastal salt marsh; not observed on-site 2-2-2 Chaparral, coastal sage scrub, valley and foothill grassland, vernal pools; not observed on-site Quercus dumosa Nuttall's scrub oak Romneya coulteri Coulter's matilija poppy Selaginella cinerascens Ashy spike-moss Viguiera laciniata San Diego County viguiera -/- IB -/- 4 -/- 4 -/- 4 2-3-2 1-2-3 1-2-1 1-2-1 Coastal chaparral; not observed on-site Coastal sage scrub; not observed on-site Chaparral, coastal sage scrub; not observed on-site Chaparral, coastal sage scrub; not observed on-site NOTE: See Table 4 for explanation of sensitivity codes.

The yellow-breasted chat, a California species of special concern when nesting, is a riparian species that is found in dense vegetation generally along watercourses or marshes (State of California 1990). This species was observed in the southern willow scrub habitat approximately 0.5 mile from the site (Planning Systems 1997). The presence of this species within the alkali marsh just adjacent to the site and the previous season's observation in habitat contiguous with the southern willow scrub on-site indicate the potential for this species to nest on-site. The least Bell's vireo and southwestern willow flycatcher, both state- and federally listed endangered species, are riparian species that nest in dense willow riparian habitats. The least Bell's vireo was not identified during focused surveys conducted in 1992 and 1994 within the alkali marsh habitat adjacent to the site to the east (RECON 1992, 1994b). However, during surveys conducted hi 1996 and 1997, nesting least Bell's vireos were observed on the Kelly Ranch property and in Macario Canyon located on the east side of the proposed Cannon Road extension. Several southwestern willow flycatchers were observed in Macario Canyon during surveys in 1996 and 1997 (as cited in USFWS 1998). It is believed, based on observational evidence, that these were transitory birds; however, the riparian habitat along the Agua Hedionda Creek is suitable habitat for this species (as cited hi USFWS 1998). The southern willow scrub on-site is contiguous with the occupied least Bell's vireo habitat and has been identified as suitable habitat for nesting southwestern willow flycatchers; therefore, there is a potential for these birds to nest on- site. The Belding's savannah sparrow is a bird that is typically found hi salt marshes, lagoons, and other habitats dominated by pickleweed (Salicornia sp.). This bird was observed on the Kelly Ranch property approximately 1.25 miles from the site within a salt pan habitat located just above Agua Hedionda Lagoon. The alkali marsh habitat identified on the site does contain pickleweed; however, this is present as a subdominant and is of a size and density that is not suitable for nesting Belding's savannah sparrows. In addition, surveys conducted hi 1997 of this habitat did not identify any individuals of this species (Planning Systems 1997). The nearest individuals were identified over one mile away hi the salt pan habitat located near Agua Hedionda Lagoon. There is a low potential for this species to nest on-site. The California gnatcatcher, a federally listed threatened species, and orange-throated whiptail, a California species of special concern, are known to occur hi the vicinity of the site (Planning Systems 1997). Both species were observed southwest of the site approximately 0.5 to 0.75 mile away. The majority of California gnatcatchers were observed in non-disturbed Diegan coastal sage scrub and the whiptails were observed hi upland areas not a part of the survey area. Neither of these species was observed during 18 the surveys of the site and they are not expected to occur as a result of the highly disturbed and degraded nature of the habitat on-site and the isolation of this habitat from the observed locations. Table 5 lists sensitive species observed on-site and those that could potentially occur on- site based on the ranges and habitat requirements of these species. The likelihood of these species occurring on-site is also presented in Table 5. 3. Sensitive Plant Communities and Habitats The following communities identified on-site are considered sensitive by the NDDB (Holland 1986): alkali marsh, southern willow scrub, disturbed mule fat scrub, disturbed Diegan coastal sage scrub, and freshwater marsh. a. Alkali Marsh Alkali marshes are typically low-lying areas with a high water table that have alkaline soils. Evaporation of ponded water often results in salts remaining on the surface. This habitat is identified in Holland (1986) and NDDB as a sensitive habitat and is a wetland habitat, all of which are considered sensitive by the U.S. Army Corps of Engineers (USAGE) and the California Department of Fish and Game (CDFG). All wetland habitats have been greatly reduced throughout then* entire range and continue to decline as a result of urbanization and are considered sensitive by state and federal resource agencies. b. Diegan Coastal Sage Scrub Diegan coastal sage scrub is restricted to the coastal areas of southern California and northern Baja California. Development and other human-related activities have seriously impacted this plant community and its associated plant and wildlife species. Estimates of loss range from 36 percent (Klopatek et al. 1979) to 85 percent (Westman 1981). These losses have accelerated rapidly in the last decade (Sawyer and Keeler-Wolf 1995). As a result, the state initiated its first habitat-based conservation planning effort, the Natural Community Conservation Plan (NCCP), using coastal sage scrub as its pilot community type. A scientific review panel, convened to provide assistance in the development of this program, has identified approximately 75 sensitive plant and animal species associated with this community, many of which occur in San Diego County. Diegan coastal sage scrub habitat is considered to be sensitive by the federal and state resource agencies, most southern California jurisdictions, and local conservation organizations. The habitat on-site is quite disturbed and degraded. While there are components of coastal sage scrub present, the habitat is approximately 70 percent weedy, non-native vegetation. This habitat is not expected to support any sensitive resources. 19 TABLE 5 SENSITIVE WILDLIFE SPECIES OBSERVED (OR POTENTIALLY OCCURRING) ON THE EL CAMINO REAL ROAD WIDENING SITE Species Status Habitat Occurrence/Comments Birds (Nomenclature from American Ornithologists' Union) Yellow-breasted chat (nesting) CSC Icteria virens KNOWN ON-SITE OTHER SENSITIVE SPECIES Dense riparian woodland.

Southern Willow Scrub and Disturbed Mule Fat Scrub Southern willow scrub and disturbed mule fat scrub are riparian communities that are generally considered wetlands and thus sensitive by CDFG and USAGE. Both habitats are found along rivers, streams, and intermittent drainages throughout southern California. Channelization of rivers, streams, and drainages for flood control and land development has resulted in cumulative losses of these habitat types throughout the state. The loss of riparian habitats in southern California has been estimated at greater than 95 percent (Faber et al. 1989). Southern willow scrub in general potentially supports several endangered and otherwise sensitive wildlife species. A wetland determination using USAGE criteria was performed by Planning Systems of Carlsbad hi July, 1998, on the disturbed mule fat scrub habitat on the site (Attachment 1). The assessment concluded that the habitat was not a wetland, since (1) it contained no obligate wetland plant species and did contain some dominant facultative or obligate upland species and (2) test pits to examine ground water and soil characteristics failed to show either hydrologic or wetland soil characteristics d. Freshwater Marsh Freshwater marsh vegetation occurs hi open bodies of fresh water with little current flow, such as ponds, and to a lesser extent around seeps and springs. This habitat is identified in Holland (1986) and NDDB as a sensitive habitat and is a wetland habitat considered sensitive by USAGE and CDFG. All wetland habitats have been greatly reduced throughout then- entire range and continue to decline as a result of urbanization and are considered sensitive by state and federal resource agencies. 4. Wetlands Three habitat types identified on-site would be considered wetlands and would fall under the jurisdiction of both USAGE and CDFG. These habitats are alkali marsh, southern willow scrub, and freshwater marsh. A USAGE 404 permit and a CDFG 1601 agreement would need to be processed, and mitigation for impacts would be required. A fourth habitat type, disturbed mule fat scrub, does not meet USAGE criteria for classification as a wetland but might be classified as habitat associated with the Agua Hedionda Greek streambed by CDFG. If so, impacts to the habitat would be subject to a streambed alteration agreement under Section 1601 of the California Fish and Game Code. A determination of the jurisdictional status of the disturbed mule fat scrub has not been made by CDFG. 5. Wildlife Movement Corridors Wildlife movement corridors are defined as areas that connect suitable wildlife habitat areas in a region otherwise fragmented by rugged terrain, changes hi vegetation, or human disturbance. Natural features such as canyon drainages, ridgelines, or areas with 24 vegetation cover provide corridors for wildlife travel. Wildlife movement corridors are important because they provide access to mates, food, and water; allow the dispersal of individuals away from high population density areas; and facilitate the exchange of genetic traits between populations. Wildlife movement corridors are considered sensitive by resource and conservation agencies. This site is located in an area that is bounded to the southwest by Kelly Ranch, where Agua Hedionda Creek and the associated riparian and marsh habitats extend to Agua Hedionda Lagoon and the Pacific Ocean. Across El Camino Real, Agua Hedionda Creek does continue to flow naturally and the channel is vegetated; however, it does flow through a housing development. From there the creek flows through undeveloped, open space that is surrounded by development within approximately one to two miles. While there is value of this area as a movement corridor that would allow some dispersal and the creation of breeding or expansion of foraging territories of several of the bird species, the value is fairly low as a result of the finite habitat available. Project Impacts Impacts are assessed for two versions of the project. As proposed and as reflected in project design plans currently available, the project includes a free right-turn lane from El Camino Real to Cannon Road that is 550 feet in length. Constructing the turn lane would require reconstruction of the outlet of the drain under El Camino Real that discharges into the alkali marsh area. All impacts to alkali marsh are associated with construction of the turn lane and the drain outlet. It is possible to redesign the turn lane so that its length is reduced to 400 feet. This redesign is acceptable to the City Engineering Department but has not been formally included in project design plans. It has been examined on a conceptual basis sufficient for the assessment of biological effects. Its principal effects would be to eliminate impacts to the alkali marsh and substantially reduce impacts to disturbed coastal sage scrub. This redesign is assessed below as the reduced-impact alternative. A. Proposed Project The proposed project will include the widening of the existing roadbed of El Camino Real and the widening of the El Camino Real bridge that currently crosses Agua Hedionda Creek by two feet on each side for a sidewalk. The existing bridge will be widened from the top of the existing road with no construction or modifications occurring from underneath. In addition, the project will include the reconstruction of one existing energy dissipator on each side of El Camino Real and construction of two energy dissipators where water flow was previously concentrated at curb cuts on each side of El 25 Camino Real. These energy dissipators will serve to improve the maintenance of existing storm drainage runoff locations by containing the runoff and keeping water velocities to a lower rate. The project will temporarily impact a total of 2.08 acres and permanently impact a total of 3.15 acres. Temporary impacts are defined as the area within the established limit of work but outside of the grading limits and will result from construction of haul roads and stockpile and staging areas. Permanent impacts are defined as the area within the established grading limits and will result from the extended roadbed, energy dissipators, the shading resulting from the widening of the El Camino Real bridge, and adjacent manufactured slopes. Table 6 presents a breakdown of temporary and permanent impacts to each vegetation community. The biological impacts of the project were assessed according to guidelines set forth hi CEQA. Mitigation is required for impacts that are considered significant under CEQA guidelines. 1. Plant Community Impacts The development will temporarily impact a total of 2.08 acres and permanently impact a total of 3.15 acres as a result of project implementation (see Table 6). Impacts to alkali marsh, disturbed mule fat scrub, and disturbed coastal sage scrub would be considered adverse and significant and will require mitigation according to CEQA guidelines. Impacts to southern willow scrub and freshwater marsh will consist of indirect effects of shading from the extension of the El Camino Real bridge by 2 feet on each side for a total of 0.004 acre of impact to southern willow scrub and 0.007 acre to freshwater marsh. These impacts would be considered adverse, but not significant because the construction will be completed solely from the top of the bridge and because the area affected would be restricted to small areas of the existing tree canopy and not to the ground surface. The actual acreage of vegetation impacted is even less than the calculated amount because the habitat also includes the unvegetated creek channel and the sparsely vegetated area north of the existing El Camino Real bridge, which accounts for 0.005 acre of the proposed freshwater marsh impacts. Impacts to eucalyptus woodland, non-native grassland, horticultural, and open/disturbed areas would be considered less than significant. There will be no impacts to mule fat scrub. 2. Wildlife Impacts The majority of the general wildlife observed consist of bird species with a high mobility; thus, there are few impacts to general wildlife associated with the project. Small mammals, amphibians, and reptiles with low mobility may be inadvertently killed during grading of the site. Impacts on general wildlife are considered less than significant. 26 TABLE 6 PROPOSED PROJECT IMPACTS Vegetation Communities NDDB Sensitive Communities Alkali Marsh Mule Fat Scrub Disturbed Mule Fat Scrub* Disturbed Diegan Coastal Sage Scrub Diegan Coastal Sage Scrub Subtotal NDDB Non-Sensitive Communities Eucalyptus Woodland Non-Native Grassland Horticultural Open/Disturbed Subtotal TOTAL Temporary Impacts 0.01 0 0.22 0.27 0 0.50 0.09 0.13 0.02 1.34 1.58 2.08 Permanent Impacts 0.03 0 0.10 0.47 0 0.50 0.09 0.14 0.06 2.25 2.54 3.04 Total Impact Area 0.04 0 0.32 0.74 0 1.10 0.18 0.27 0.08 3.59 4.12 5.22 *A wetland delineation for the project determined that the disturbed mule fat scrub on- site does not meet U.S. Army Corps of Engineers criteria for a wetland habitat. Indirect impacts associated with project implementation include an increase in noise due to an increase in vehicular traffic and an increase in litter and pollutants into adjacent wildlife habitat. These impacts are not expected to reduce the wildlife populations of the area below self-sustaining levels and are thus considered less than significant. 3. Sensitive Biological Resources Impacts a. Sensitive Plants No sensitive plants were observed or are expected to occur on-site and, thus, there will be no significant impacts incurred as a result of project implementation. b. Sensitive Wildlife The project will impact approximately 0.004 acre of southern willow scrub, which would impact the least Bell's vireo, southwestern willow flycatcher, yellow warbler, tricolored blackbird, and yellow-breasted chat habitat as a result of increased shading from the widening of the bridge that crosses Agua Hedionda Creek. Because of the small area of impact and the fact that these birds were not observed within the permanent impact area either during 1997 (Planning Systems 1997) or the current surveys, the impact would be considered less than significant. In addition, the USFWS biological opinion (USFWS 1998) for the adjacent Cannon Road project states that road construction in this area "is not likely to jeopardize the continued existence of the least Bell's vireo [or] southwestern willow flycatcher." It also states that this adjacent project will not adversely affect critical habitat designated for these species as the work is proposed outside of these designated areas. Because the proposed El Camino Real road widening project is adjacent and contiguous with the Cannon Road project, it follows that the expected impacts will be the same. Approximately 0.49 acre of potential roosting and foraging habitat for the white-tailed kite will be impacted within the alkali marsh, southern willow scrub, non-native grassland, and eucalyptus woodland. White-shouldered kites are fairly common within the county and although, if present, impacts would be locally adverse, they would be considered less than significant. c. Sensitive Plant Communities The project will either temporarily or permanently impact 0.74 acre of sensitive upland habitat and 0.37 acre of wetland habitats (see Table 6). Upland impacts include 0.27 acre of temporary impacts and 0.47 acre of permanent impacts to disturbed Diegan coastal sage scrub. Wetland impacts consist of the following temporary and permanent impacts: 0.01 acre of temporary and 0.03 acre of permanent impacts to alkali marsh; 0.004 acre of permanent impacts to southern willow scrub; 0.22 acre of temporary and 0.10 acre of permanent impacts to disturbed mule fat scrub; and 0.007 acre of permanent impacts to 28 freshwater marsh. The disturbed mule fat scrub does not qualify as a wetland under USAGE criteria but may be subject to CDFG jurisdiction. For purposes of impact assessment and mitigation, it is considered a sensitive plant community in this report. Impacts to disturbed Diegan coastal sage scrub, alkali marsh, and disturbed mule fat scrub will be considered significant and will require mitigation in the form of habitat replacement and/or enhancement. Impacts to southern willow scrub and freshwater marsh will be considered adverse, but less than significant for the reasons stated above. d. Wildlife Movement Corridor There will be no impacts to wildlife movement corridors. e. Cumulative There are no cumulative impacts associated with this project. B. Reduced Impact Alternative As described earlier in this section, this alternative would reduce the length of the turn lane from El Camino Real eastbound to Cannon Road from 550 to 400 feet. This would allow the area of disturbance in that part of the project site to be reduced. The environmental fence limiting the area of construction activity could be relocated to exclude the alkali marsh and an area of disturbed coastal sage scrub from the construction zone (Figure 4). As a result, the redesigned project would have no impacts on alkali marsh and impacts on disturbed coastal sage scrub would be reduced from 0.74 acre to 0.35 acre. The redesigned alternative will temporarily impact a total of 1.76 acres and permanently impact a total of 2.89 acres. Temporary and permanent impacts are defined the same way as for the proposed project. Table 7 presents a breakdown of temporary and permanent impacts to each vegetation community. Impacts and mitigation were assessed in the same way as for the proposed project. Impacts to plant communities and other biological resources for this alternative would differ from the proposed project's only with respect to alkali marsh, which would not be impacted, and disturbed coastal sage scrub. Permanent impacts to coastal sage scrub would be reduced to 0.06 acre of temporary impacts and 0.29 acre of permanent impacts. Mitigation Measures Mitigation is required for impacts that are considered significant, including impacts to listed species, sensitive plant communities and habitats, and wetlands.

Mitigation measures typically employed include resource avoidance, habitat replacement, or the paying of fees into a mitigation bank. A. Proposed Project This is the project for which plans are available. The City has indicated a willingness to implement the project changes that would result in the Reduced Impact Alternative described in this report. In that case, the mitigation described for the proposed project will not be required. Reduced mitigation requirements for the Reduced Impact Alternative would be required instead. Mitigation for the proposed project is presented below for purposes of comparison. Mitigation for 0.47 acre of permanent impacts and 0.27 acre of temporary impacts to disturbed Diegan coastal sage scrub would be mitigated by the revegetation and enhancement of the temporarily impacted areas as well as the newly created manufactured slopes adjacent to El Camino Real. This should provide 0.39 acre of higher quality Diegan coastal sage scrub as mitigation for the loss of 0.74 acre of disturbed habitat. Significant permanent impacts to 0.04 acre of alkali marsh would be mitigated at a 1:1 ratio both on- and off-site. The 0.01 acre of alkali marsh temporarily impacted on-site would be restored, and the remaining 0.03 acre permanently impacted would be mitigated by restoration of 0.03 acre of alkali marsh hi the Agua Hedionda wetland area south and west of the project site or hi another site acceptable to the City of Carlsbad, USFWS, and CDFG. Impacts to disturbed mule fat scrub would be mitigated by the restoration of 0.31 acre on- site and an additional 0.01 acre hi adjacent areas off-site. The mitigation for alkali marsh and disturbed mule fat scrub impacts will be designed to be consistent with or comparable to mitigation required in Biological Opinion (B.O.) 1-6-97-F-51 for similar impacts from the Cannon Road Reaches 1 and 2 project. Success criteria, monitoring, maintenance, and buffering of the mitigation site shall also be consistent or comparable with that described hi B.O. 1-6-97-F-51. Temporary impacts to alkali marsh and disturbed mule fat scrub totaling 0.23 acre shall be mitigated by revegetating and restoring the impact area to the original condition (condition before disturbance), as with the alkali marsh, or to a higher quality habitat, as with the disturbed mule fat scrub. Revegetation shall include remedial work such as decompaction and surface treatment of the ground and restoration of natural contours. Revegetation must be monitored for a period of three years. 32 To avoid direct or indirect (i.e., noise) impacts to any breeding sensitive bird and raptor species that may be present in or adjacent to the riparian and eucalyptus habitats on-site, a clearance survey should be conducted by a qualified biologist prior to grading to ensure that no active nests will be impacted by project implementation. This will only be required if grading and vegetation removal is scheduled to begin within the breeding season, which is approximately from March 1 through September 30. Impacts to wetland habitats will require a USAGE 404 permit and CDFG 1601 agreement. If mitigation required by the 404 permit and/or 1601 agreement differs from the mitigation required above, the mitigation required by the USAGE 404 permit and the CDFG 1601 agreement shall take precedence. B. Reduced Impact Alternative Mitigation for 0.29 acre of permanent impacts and 0.06 acre of temporary impacts to disturbed Diegan coastal sage scrub would be mitigated by the revegetation and enhancement of the temporarily impacted areas, the newly created manufactured slopes adjacent to El Camino Real, and other areas within the right-of-way. This would provide 0.39 acre of restored Diegan coastal sage scrub as mitigation for the loss of 0.35 acre of disturbed habitat. Temporary and permanent impacts to disturbed mule fat scrub would be mitigated by the restoration of 0.31 acre of higher quality habitat on-site. The mitigation for alkali marsh and disturbed mule fat scrub impacts will be designed to be consistent with or comparable to mitigation required in B.O. 1-6-97-F-51 for similar impacts from the Gannon Road Reaches 1 and 2 project. Success criteria, monitoring, maintenance, and buffering of the mitigation site shall also be consistent or comparable with that described in B.O. 1-6-97-F-51. Revegetation shall include remedial work such as decompaction and surface treatment of the ground and restoration of natural contours. Revegetation must be monitored for a period of three years. To avoid direct or indirect (i.e., noise) impacts to any breeding sensitive bird and raptor species that may be present in or adjacent to the riparian and eucalyptus habitats on-site, a clearance survey should be conducted by a qualified biologist prior to grading to ensure that no active nests will be impacted by project implementation. This will only be required if grading and vegetation removal is scheduled to begin within the breeding season, which is approximately from March 1 through September 30. Impacts to disturbed mule fat scrub habitat may require a CDFG 1601 agreement. If mitigation required by the 1601 agreement differs from the mitigation required above, the mitigation required by the CDFG 1601 agreement shall take precedence. 33 References Cited American Ornithologists' Union 1983 Check-list of North American Birds. 6th ed.

On July 13,1998, Fred Sproul, biologist, and Greg Evans, Landscape Architect, surveyed the proposed site along El Camino Real to determine if vegetation identified by City environmental consultant RECON is indeed wetland vegetation as defined by U. S. Army Corps of Engineers guidelines. Our assessment of existing the vegetation follows. The project site is comprised of the roadway edge, an existing manufactured slope supporting the raised roadbed, and a bench area that transitions from this upland - condition to a wetland corridor west of the project area which is linked to Upper Agua Hedionda Lagoon. The linear study area extends from the proposed Cannon Road R.O.W. northward along El Camino Real approximately 500 feet to an existing box culvert providing drainage beneath El Camino Real from points east. An area of Mulefat scrub, approximately 0.10 acre in size, occurs on a bench within the present construction zone, located approximately between roadway Station 447+50 and Station 449+75. Mulefat Scrub is identified on-site where Mulefat (Baccharis salicifolia) is the dominant vegetative cover. On the site it occurs in association with several other plants including: Western ragweed (Ambrosia psilostachva). Coyote brush (Baccharis pilularis var. consanguinea) and Saltgrass (Distichilis spicata). This community is bordered on its lower boundary by weed infested Ruderal vegetation. That these plants occur in association identifies this area as a transitional community between an upland plant association and a wetland plant association. None of the plants occurring in this Mulefat scrub are identified as obligate wetland species as identified in the "National List of Plant Species That Occur in Wetlands: California Region O", May 1988. Several of the dominant species observed are equally likely to occur in upland or wetland conditions. Some of the dominant species observed are facultative or obligate upland plants. To be considered a jurisdictional wetland, the U.S. Army Corps of Engineer's (USACOE) requires that three wetland components occur simultaneously: wetland 2111 PALOMAR AIRPORT ROAD • SUITE 100 • CARLSBAD.CA 92009 • (760)931-0780 • FAX (760) 931-5744 soils, wetland hydrology, and wetland vegetation. Two pits in excess of 24" deep were dug to examine ground water and soil characteristics in the Mulefat scrub area. The results failed to show either hydrologic or wetland soil characteristics. A Wetland Determination of the subject Mulefat scrub was performed (see attached Wetland Determination). The results conclude that the subject Mulefat scrub is not a wetland. We recommend that the City minimize impacts to this transitional plant community. Impacts to Mulefat scrub can be lessened by strictly limiting the construction zone.

Implementation of the proposed project would shift traffic slightly closer to existing sensitive uses in the mobile home park adjacent to the project, as well as allow for acceptable level of service operation of future anticipated traffic volumes. It is anticipated that future noise levels will increase by 2.8 decibels at the mobile home park due primarily to greater projected future traffic volumes. Increases in exterior noise levels of less than 3 decibels are not considered to be noticeable. Therefore, because noise levels in the mobile home park currently exceed City of Carlsbad exterior noise standards, implementation of the proposed project is not expected to result in significant noise impacts. No mitigation is required. Additionally, noise will result from construction. Due to the short-term variable nature of construction noise, no significant construction noise impacts are anticipated. Introduction The proposed El Camino Real road widening project is located in the segment of road in the city of Carlsbad where El Camino Real crosses Agua Hedionda Creek on a bridge (Figures 1 and 2). The project site is approximately 0.9 mile west of the intersection of El Camino Real and College Boulevard and about a mile east of the intersection of El Camino Real and Tamarack Avenue. The segment includes the future intersection with Cannon Road, just west of the bridge over Agua Hedionda Creek. The project is the improvement of El Camino Real for approximately 1,600 linear feet, including the existing bridge over Agua Hedionda Creek, a segment approximately 440 feet east of the bridge, and a segment approximately 1,020 feet west of the bridge. The project site includes the future intersection of El Camino Real with Cannon Road. The project will widen the bridge and an area west of the bridge. The bridge is presently 108 feet wide; the project would add two feet to each side to increase the width to 112 feet. El Camino Real would be widened west of the bridge by adding up to 17 feet to the width of paving on the north side and up to 29 feet to the width of paving on the south side. The widening would result in a paved width for El Camino Real of 106 feet east of the Cannon Road intersection and 138 feet west of that intersection to allow for planned geometry and striping at the future intersection with Cannon Road to the south.

The Carlsbad Circulation Element shows Cannon Road extending northeasterly from El Camino Real to where Cannon Road presently stubs out at the city limit in Oceanside, but that extension is not an active project at this time. Project plans do include, however, an extension northerly from the El Camino Real/Cannon Road intersection to an existing blacktop road giving access to properties in that area. Project plans also include channel improvements to Agua Hedionda Creek under the El Camino Real bridge. Those channel improvements would extend southerly and westerly under the planned Cannon Road bridge. Analysis Methodology A. Applicable Standards and Definitions of Terms The community noise equivalent level (CNEL) is a 24-hour A-weighted decibel average sound level [dB(A) LJ from midnight to midnight obtained after the addition of 5 dB to sound levels occurring between 7:00 P.M. and 10:00 P.M. and 10 dB to the sound levels occurring between 10:00 P.M. and 7:00 A.M. A-weighting is a frequency correction that often correlates well with the subjective response of humans to noise. The 5 dB and 10 dB penalties added to the evening and nighttime hours account for the added sensitivity of humans to noise during these time periods. Impacts to future sensitive receivers were evaluated in relation to the noise level standards promulgated in the City of Carlsbad's adopted General Plan Noise Element. The Noise Element of the City of Carlsbad states (City of Carlsbad 1994): Policy C.5: . . . sixty (60) dBA CNEL is the exterior noise level to which all residential units should be mitigated. Policy C.9: Discourage the exclusive use of noise walls in excess of 6 feet in height as mitigation for noise along Circulation Element roadways. For comparing changes in ambient noise levels along the roadway due to implementation of the proposed project, a change in exterior noise levels of 3 dB is considered perceptible; changes of less than 3 decibels in general are not noticeable in the outdoor environment (Bolt, Beranek, and Newman 1973:1-20; Beranek 1988:598-599). Therefore, if the increase in traffic-generated noise along the roadway is less than 3 decibels, in general, it is not considered a significant impact. Construction noise is regulated by Carlsbad Municipal Code Section 8.48. Generally, construction activities are limited to the daytime hours, with no construction allowed on Sundays or holidays except hi the event of an emergency. B. Existing Noise Level Measurements Existing noise levels adjacent to the project site were measured using a Larson-Davis Model 720 Type 2 Integrating Sound Level Meter, serial number 0274. The following parameters were used: Filter: A-weighted Response: Slow (1/8 second) Time History Period: 5 seconds The meter was calibrated prior to the day's measurements. Four ground-floor measure- ments (five feet above the ground) were made: two for approximately 30 minutes each and two for approximately 15 minutes each. C. Traffic Noise Analysis 1. Traffic Parameters Existing traffic volumes in the project vicinity are estimated to be 24,000 average daily trips (ADT) on El Camino Real (San Diego Association of Governments 1997). Series 8 future traffic volumes are projected to be approximately 39,000 ADT on El Camino Real. 2. Analysis of Traffic Noise Noise generated by traffic on El Camino Real was projected using the Federal Highway Administration Noise Prediction Model (1979), which uses California vehicle noise emission levels (California Department of Transportation 1983). The alignment and elevations of the roadway were also obtained from the 1 inch equals 40 feet scale maps prepared for the project, as well as from AutoCAD files provided by the project engineer (Matthews, per. com. 1998). Existing Conditions The project site is El Camino Real in the vicinity of Agua Hedionda Creek. North of El Camino Real and east of Agua Hedionda Creek is a mobile home park. North of El Camino Real and west of the creek is a nursery. South of El Camino Real is open space. The only existing sensitive receivers in the vicinity of the proposed project are the mobile homes. The mobile homes are essentially at the roadway grade. There is an existing approximately five-foot-high wall along El Camino Real adjacent to the mobile home park as shown in Figure 3. However, this wall functions primarily as a privacy wall and is not a sufficient traffic noise barrier due to its height and configuration. Noise measurements were taken around the project site on Tuesday, May 19, 1998, between the hours of 12:40 A.M. and 2:40 P.M. The weather was warm and sunny. Two approximately 30-minute measurements and two 15-minute measurements were made. Figure 3 shows the locations of the measurements. These locations were chosen to obtain existing noise levels in the vicinity of the project in order to assess the existing noise environment. The noise measurement data are contained in Attachment 1. Measurement location 1 is at the western end of the existing mobile home wall adjacent to El Camino Real. This measurement was slightly above the roadway grade. During the 30-minute interval, the average noise level was 73.1 dB(A). Measurement location 2 is down the slope on the south side of El Camino Real west of Agua Hedionda Creek as shown in Figure 3. At this location the meter was below the roadway grade. During the 30-minute measurement interval, the average noise level was 62.2 dB(A). Measurement location 3 is on the El Camino Real median east of Agua Hedionda Creek. During the 15-minute measurement interval, the average noise level was 74.1 dB(A). Measurement location 4 is located at the bottom of the slope in the Agua Hedionda Creek channel north of El Camino Real. At this location the meter is well below the roadway grade. During the 15-minute measurement interval, the average noise level was 61.6dB(A). Based on these noise measurements, existing noise levels in the mobile home park currently exceed the City's 60 CNEL exterior noise standard for residential uses. Acoustical Environment and Impacts Due to the Project A. Traffic Noise The proposed project would not widen the pavement adjacent to the mobile home park and would widen both the north and south sides of the bridge by two feet. West of the bridge, the project would widen the north side of El Camino Real by approximately 17 Mobile Home Park Agua Hedionda Creek FIGURE 3 Measurement Locations and Existing Roadway Configuration feet and would widen the south side of El Camino Real by approximately 29 feet. Additionally, the project would reconfigure the roadway median to incorporate a westbound left-turn lane at the intersection with future Cannon Road. However, the proposed project does not include the construction of future Cannon Road. There are no existing sensitive receivers west of the bridge adjacent to the proposed project. The only existing sensitive receivers in the project vicinity are at the mobile home park east of the bridge. Adjacent to the mobile home park, El Camino Real is full width and is currently striped to transition from three to two lanes westbound and is striped for three lanes eastbound. The proposed project would restripe the westbound lanes such that there would be three lanes adjacent to the mobile home park. As indicated above, the roadway is not being widened adjacent to the mobile home park. Restriping El Camino Real from five lanes (two westbound; three eastbound) to six lanes (three westbound; three eastbound) adjacent to the mobile home park will have the effect of shifting the noise source (traffic) slightly closer to the mobile homes. In the FHWA model, this distance is expressed as the "equivalent lane distance." The restriping will effectively reduce the equivalent lane distance from approximately 78 feet to 70 feet. This eight-foot reduction in equivalent lane distance is expected to increase noise levels in the mobile home park by approximately 0.7 decibel. The road widening west of the bridge is being accomplished to maintain acceptable levels of service for the future anticipated traffic volumes. Therefore, existing and future traffic speeds are not anticipated to change with implementation of the proposed project. If the project were not implemented, future traffic speeds would be expected to decrease. Additionally, implementation of the proposed project would not change the vehicle mix or distribution. Therefore, the increase in ADT from 24,000 ADT existing to a future traffic volume of 39,000 ADT would increase noise levels in the vicinity of the project by approximately 2.1 decibels. In combination with the 0.7-decibel increase due to the decrease in equivalent lane distance discussed above, future traffic noise levels adjacent to the mobile home park are expected to increase by approximately 2.8 decibels relative to existing noise levels. It should be noted that with the future construction of Cannon Road, a signal will be installed at the intersection of Cannon Road and El Camino Real. The effect of this signal will be to reduce the average traffic speed on El Camino Real. Therefore, the actual increase in future noise levels adjacent to El Camino Real is expected to be less than the 2.8 decibels indicated above. Because existing noise levels at the mobile home park exceed the City's 60 CNEL standards, noise level increases of less than 3 decibels are generally not considered significant. There are no other existing sensitive receivers in the project vicinity. Therefore, implementation of the proposed road widening project is not anticipated to create any significant noise impacts. B. Construction Noise As indicated above, construction noise is regulated by Carlsbad Municipal Code Section 8.48. Generally, construction activities are limited to the daytime hours on weekdays (including Saturday). Temporary construction noise impacts vary markedly, because the noise strength of construction equipment ranges widely as a function of the equipment used and its activity level. Earth-moving (grading) activities are the noisiest sources during construction, with equipment noise ranging from 70 to 95 dB(A) at 50 feet from the source. As a general rule, noise decreases by 6 dB for each doubling of distance for a flat site (no topography). Therefore, noise levels from quieter construction noise sources are expected to be below 75 dB(A). However, noise levels from the louder construction equipment may still be above 75 dB(A) 500 feet from the source. Construction noises are expected to occur during daylight hours on weekdays, when residential noise sensitivity is generally lower than during morning and evening hours and on weekends. Nocturnal noise-generating construction activities are expected to occur only as emergency operations are necessary. Construction activities will shift as construction of the roadway progresses, thereby reducing the length of time that any single location would be impacted. Although construction noise impacts may be intrusive, they are generally considered below significant levels because of the progressive construction of the project. No single location will experience long-term construction noise impacts. Mitigation No significant noise impacts are anticipated to existing sensitive receivers. No mitigation is required. 9 References Cited Beranek, Leo L., editor 1988 Noise and Vibration Control. Rev. ed. Institute of Noise Control Engineering. Washington, D.C.
