STATEMENT OF NON-SIGNIFICANT ENVIRONMENTAL EFFECTS If you have answered yes to any of the questions in Section I but think the activity will have no significant environmental effects, indicate your reasons below: For the purposes of this Part I analysis, the "project" is considered to be all of the previously described Villages, for a total of 669 dwelling units on 290.4 acres. Individual villages will be discussed separately where necessary. 1) The project will not significantly impact or change present or future land uses in the vicinity of the project area because the area is part of a larger developing residential master plan. The Calavera Hills Master Plan includes 800 acres and has approximately 1100 existing dwelling units. The proposed project has been planned for both in the master plan and the Zone 7 LFMP. As shown on table for question 3.a., the proposed number of units is 126 fewer than what is allowable per the Zone 7 Local Facilities Management Plan. One change in product type occurs in Village H, which is proposed for 13 single family custom estates instead of 42 multi-family units, as permitted by the Local Facilities Management Plan based on this Village's Growth Control Plan. This is not considered a significant land use change. 2) The proposed project, when implemented, will effect the use of the Calavera Hills Community Park. The effect of the development will increase the demand on this park and other future City parks in the Northeast Quadrant to the level anticipated in the City's Growth Management Program. Areas of aesthetic value which are considered significant have been preserved as part of the existing master plan and also through detailed constraints mapping for Zone 7, and will not be impacted by the proposed project. 3) The proposed project will not affect the functioning of an established neighborhood because the new villages are in compliance the Master Plan and will provide any necessary infrastructure improvements or upgrades to ensure that public services will meet required standards. To avoid impacting existing neighborhoods the proposed tentative maps have been designed to gain access from existing and future arterial streets rather than existing local streets. Development of the proposed projects will actually improve access to the existing neighborhoods by the constructions of College Avenue and the remainder of Tamarack Avenue which will provide a linkage to the existing College Avenue and Highway 78 in Oceanside. 4) No community residents will be displaced because the project area is currently vacant.' 5) The proposed tentative maps could increase the number of low and moderate priced housing in the City of Carlsbad. The Calavera Hills Master Plan requires that "Villages K and L-2, by including lower cost condominiums for sale and/or rental housing, provide the City with affordable housing and housing for the elderly." The applicant, by providing smaller condominium units in Village K, will fulfill this requirement and provide moderately priced housing in this portion of Carlsbad. . . 6) Existing housing will not be affected. The proposed project will "fill" a demand for additional housing, not "create" a demand. This question is more applicable for non- residential proposals. 7) The natural features of the subject property are primarily rolling hills and ravines and steep slopes and associated biological habitat. Calavera Lake also is in the vicinity. All of these features are common to Carlsbad and the rest of the county. 8) An updated archaeology study was done for the entire master plan area in March, 1990. This study found one potentially significant site in Village W that required additional testing. If it is determined that this site will be impacted by the development of Village W it will be evaluated in accordance with the recommendations of the letter dated May 22, 1990, attached to this document. 9) No scarce natural resources are known to exist in the project area and thus, their use, extraction or conservation will not be affected. 10) A biological survey was conducted on the property in January, February, May and June 1990. The results of those surveys are summarized in the attached report. The major impacts are summarized as follows: 11) Several sensitive biological features may be impacted by the proposed project. Wetland habitat of 0.11 acre of riparian scrub will be impacted where Elm Avenue bisects Village H. The applicant will be required to obtain a California Department of Fish and Game Streambed Alteration Agreement for the elimination of this area. The enhancement of the existing wetland habitat in Village H or Village X would be appropriate mitigation for the loss of 0.11 acre of riparian scrub eliminated by the widening of Elm Avenue. Approximately 8.9 acres of coastal sage dominated by artemisia and encompassing a territory for a single pair of California Gnatcatchers may be impacted by the development of Village K. Three water line easements associated with development of Village Q will pass through the California gnatcatcher territory found in Village K. Two of the easements will follow existing dirt roads or disturbed areas and one easement is for the most part, outside of the gnatcatcher territory. While the impact to the preferred habitat of the existing gnatcatcher territory in Village K is not significantly impacted by the three easements, it is not known if the one pair of gnatcatchers will remain after construction of these waterlines are completed. It is recommended that an additional survey of this area be conducted after the installation of the permitted water lines. Based on the results of this subsequent survey, the need for mitigation will be determined. The attached biological survey dated June 1990 provides three possible mitigation measures if mitigation is deemed necessary. Several other sensitive plant species will be impacted by proposed development but not significantly. . The impacts to birds of prey and sensitive mammal and reptile species potentially present and present on-site is considered an insignificant cumulative adverse impact. For additional details see the attached Biological Report dated June 1990. 12) The proposed project will drain primarily to Aqua Hedionda Lagoon (95%) with a small portion of Village 12 draining north to Buena Vista Lagoon. To ensure that impacts are insignificant the applicant will comply with all of the City of Carlsbad's standard engineering practices to control the amounts and velocities of drainage from this project. During the construction phase water quality impacts will be mitigated to a level of insignificance by the construction of erosion control devices to the satisfaction of the City Engineer. 13) Agricultural lands will not be impacted by the proposed project because the area is not used for farming. The project is adjacent to the existing residential development of Calavera Hills. In terms of prime agricultural soils, a review of the soils map in the previous EW (#403) prepared for the master plan shows that no prime soils are found within the proposed project area and that past farming efforts were unsuccessful because the soils were thin, extremely rocky and almost unfarmable. 14) The proposed project will not act as a catalyst to encourage development of presently undeveloped areas because the project is implementing the Calavera Hills Master Plan, part of which has already been developed. This area has always been designated for residential development by the City of Carlsbad's General Plan and the proposed development is in conformance with this plan. Other major landholdings in the Northeast Quadrant of the City have been in the planning stages for several years and will continue that process regardless of the development activity on this site. 15) The proposed tentative maps have been designed in accordance with all applicable established environmental standards and do not require any variances from these standards. Detailed noise studies have been completed for each of the proposed tentative tract maps by the firm of Mestre Greve Associates. These studies show all of the proposed projects can be buffered from noise impacts to comply with the City of Carlsbad's Noise Policy. The projects have been designed in compliance with the recommendations of these reports and are in compliance with the City of Carlsbad's Noise Policy. Copies of the noise reports for the individual tentative tract maps are attached. 16) The proposed project is being implemented as part of the Calavera Hills Master Plan. That plan established certain development standards and procedures that each Village must comply with as it develops. The project also is being carried out in accordance with the conditions of the Zone 7 LFMP, which is part of the City's overall general plan.The proposed project will consist of six tentative maps that will complete the development of the residential portion of the Calavera Hills Master Plan. The impacts of the development of this area were addressed by the previously certified EIR-403. . 17) A permit will be required from the California Department of Fish & Game for the elimination of the riparian scrub area adjacent to Elm Avenue in Village H. This requirement is discussed in sections 10 & 11 of this document and the Biological Study that is attached. 18) The project does not propose any uses requiring a conditional use permit. Site plans and tentative map will conform to zoning requirements, negating the need for variances. 19) The residential land use envisioned will not involve the use of hazardous materials. Standard construction materials will be used. Potentially hazardous materials are not known to exist in the area and have not been found in other areas of Calavera Hills. 20) The proposed project will not involve construction of facilities in a floodplain. The subject property is not located near any creeks or rivers. 21) The proposed project is not located in an area of an active fault. The nearest fault is approximately 7 1/2 miles west of the property, which is the Rose Canyon Fault. 22) While under construction, the proposed project will generate typical amounts of dust. The City will require that the site be watered before and during grading operations to control the amount of dust created by the proposed development. Grading will have to comply with SDAPCD and CARB standards and requirements in Title 24 of the California Administrative Code to control dust and emissions. After construction, there will be no significant amounts of dust generated from the new residential subdivisions. 23) Vegetation will be removed from the property for preparation for building--however, the vegetation is not anticipated to be burned, rather it will be scraped off and hauled away. 24) The proposed project will result in incremental changes to the region's air quality and the water quality of Aqua Hedionda Lagoon. However, Carlsbad is in compliance with regional air quality standards because the City's Land Use and Circulation Elements are included in SANDAG projections which then become part of the San Diego Air Pollution Control District's projections. Because this proposed project is in compliance with the general plan, it therefore meets regional projections which anticipate incremental changes. Incremental changes are not considered significant. The water quality of Aqua Hedionda Lagoon has been incrementally impacted for years by continuing upstream development in Calavera Hills and other areas within the watershed. The drainage and erosion control devices required for these projects will reduce their impact to a level of insignificance. . 25) The project will incrementally increase fuel consumption during construction. When completed, a residential subdivision will not consume significant amounts of fuel. San Diego Gas & Electric Company is able to supply natural gas and electricity to new housing projects throughout San Diego County. 26) The project proposes some development on 25% and greater slopes. This occurs in Villages H,K,L-2,U,W, and X, and involves approximately 25.8 acres. This represents approximately 13.7% of the area that will actually be graded by these tentative maps. This figure of 25.8 acres is only 8.9% of the total area included within the boundaries of Villages H,L-2,R,U,W,X and Y. In addition over 75% of the existing slopes in excess of 25% within these villages will be preserved. A substantial portion of this encroachment is created by College Boulevard and other roads need to provide access to these villages. The chart below breaks down the amount of encroachment into 25% slopes by each village. ACRES OF ENCROACHMENT VILLAGE INTO 25% SLOPES H 5.91 K 4.91 L-2 .68 R --0-- U 3.03 W 4.92 X 2.17 Y --0-- TOTAL 25.8 27) There will be a significant change to existing landform with grading amounts of more than one million to create roads and building pads on the existing hilly terrain to achieve acceptable engineering standards. Much of this grading will be necessitated by the construction of Elm Avenue and College Avenue two Circulation Element Roadways. The rocky terrain of the undeveloped portion of the Calavera Hills Master Plan, makes it infeasible to develop projects that are not sensitive to the existing terrain. The amount of grading proposed for these tentative maps is 7864 per acre, which is in conformance with the requirements of the City of Carlsbad's Hillside Development Ordinance. The following paragraphs explain how the grading for this project complies with the City of Carlsbad's Hillside Development Ordinance. Alterations to existing land form, resulting from the proposed development, may appear significant unless viewed within the context of the overall project. Several measures have been incorporated within the project's design to insure that grading associated impacts will be minimized to the extent feasible. First, project grading has been designed to balance onsite, thus eliminating impacts normally associated with in import/export grading operation. It is important to note that, due to the wide variation in topographic conditions between villages, this balance may require that more than one village be included in each grading phase. . Additionally, over one half of the project site's 290.4 total acres will be retained as undeveloped open space. Grading for the project will require a total cut of 1,165,147 cubic yards and a total fill of 1,286,907 cubic yards confined to an area of approximately 159 acres which includes both onsite (approximately 152 acres) and offsite (approximately 6.8 acres) improvements. A "gross" grading ratio of 8094 cubic yards/acre results when the high volume of fill is divided by the area of grading activity. A "net" ratio of 7097 cubic yards/acre is achieved when the grading directly associated with the construction of College Boulevard (both on- and off site: 208,142 cubic yards fill) is deducted from the project grading totals. Following the exclusion of this circulation element roadway, the grading ratio for the remaining villages of Calavera Heights falls within the Hillside Development Ordinance's "acceptable" range of less than 8000 cubic yards/acres. Within the remainder Villages of Calavera Hills, there are three areas that involve the construction of slopes over 30 feet in height. Those areas are located on offsite College Blvd., within Village L-2 and Village K. Approximately 600 feet south of the Village X boundary exists a fill slope of approximately 60 feet. This slope is associated with the grading necessary to construct College Blvd. which is a major Circulation Element roadway. Within L-2 a fill slope located between an existing water tank and Cay Drive is approximately 50 feet in height. This graded slope is due to the existence of a public utility and an existing public right-of-way (Cay Drive). Finally, within Village K a fill slope exists west of Glasgow Drive. The developed area (K-3) is constructed on all sides by existing constructed public right- of-ways which restrict pad elevations and project access points. Additionally, to meet City intersection spacing requirements, the project entry is at street 'X' which necessitates grading into the area requiring the 45 feet of fill slope. 28) The proposed project, as part of the City's Growth Management Program, will not substantially impact utilities, sewers, or streets because the project will provide its share of improvements so that acceptable performance standards are maintained. For example, there are special conditions in Zone 7 which pertain to drainage, circulation, and sewer facilities which must be adhered to prior to developing any of the Villages in Zone 7. 29) Soil erosion will not increase significantly as a result of the proposed project. Maintenance of all manufactured slopes will be with standard erosion control techniques. Permanent landscaping will be established as quickly as possible on common areas as well as private yards. During the construction, standard erosion control facilities will be installed to reduce the amount of erosion to a level of insignificance. 30) Wildlife habitat has been discussed in question #s 10 & 11 and the attached Biological assessment for this project. S . 31) New light will be produced by streetlights and house lights in the new subdivisions. The streetlights will be conformance with the City's standards. The proposed project is located in an urbanizing area, and will introduce new light into a previously darkened part of the city. The project specific impacts of light and glare from streetlights,houselights and vehicles can be lessened to a level of insignificance. These projects will, in conjunction with other past, present and future projects contribute to light and glare created by all developments occurring in this portion of the City. Lighting installed for these projects will be in conformance with all applicable City standards. III. COMMENTS OR ELABORATIONS TO ANY OF THE QUESTIONS IN SECTION I (If additional space is needed for answering any questions, attach additional sheets as needed.) Signature (Person Completing Report) Date Signed . . INTRODUCTION AND BACKGROUND This ETA addresses the proposed tentative tract maps for the remaining residential in the Calavera Hills Master Plan. The applicant Lyon Communities Inc. is submitting 6 tentative tract maps that will cover Villages H,K,L-2,R,U,W,X, and Y. The individual tentative tract maps are described below. For additional details see the chart below and the tentative maps.

This Effi was based on a maximum development of 3452 dwelling units and 10 acres of commercial. Since that time approximately 1000 dwelling units have been constructed in the Master Plan area. Also a number of changes have been made to City ordinances and policies that have resulted in substantially less dwelling units and more open space in the Calavera Hills Master Plan. At this time the maximum number of dwelling units that can be occupied is 2333 and there will be at least 10 acres of commercial in the Master Plan. All of the proposed development will be occurring in portions of the Master Plan that were designated for development by the original Calavera Hills Master Plan that was addressed by Effi 403 that was previously certified by the City Of Carlsbad. The proposed projects will gain access from existing and future arterial roadways that were addressed by the . . previously certified EW. The proposed developments will not alter these roadways or create any new Circulation Element Roadways. These Circulation Element Roadways will allow construction traffic to access the developable areas without driving through existing residential areas or using local streets. This will serve to minimize the impact on the existing residents of the Master Plan. Attached to this ETA are the following updated studies that are in compliance with current standards: Biology Archeology Noise Soils Traffic The Biological and Archeological studies also address the offsite impacts created by the extension of College Boulevard from the southerly edge of the Master Plan to the future alignment of Cannon Road. This alignment will follow the alignment of College Avenue as shown on the Circulation Element of the Carlsbad General Plan. Construction of this portion of College Avenue will have minimal environmental impacts since the vast majority of this portion of the College Avenue alignment has been under agriculture for a number of years. Traffic and other public facilities were addressed in the Local Facilities Management Plan for Zone 7. This plan addressed the impacts of existing and future development in the Calavera Hills Master Plan. The tentative maps that are being addressed by this ETA represent the remaining development in Zone 7 except for the 10 acre commercial site. The traffic impacts created by future development in Zone 7 will be created by these projects. The developer of these projects will be responsible for implementing the traffic mitigation measures and improvements called out for in the Zone 7 Local Facilities Management Plan. A copy of the Circulation section of the Zone 7 Local Facilities Management Plan and the traffic studies used to prepare that section of the plan are attached to this study. The purpose of this ETA is to show that the impact of the proposed development which is in compliance with the approved Master Plan, will not create any impacts that were not addressed by the previously certified Effi. The updated studies and information in this ETA addresses new ordinances and policies that have come into existence since the original Effi was certified. After a careful review of the original Effi, the updated studies and the information in this ETA the applicant believes it will be possible for the City to issue a Mitigated Negative Declaration for these projects. The information and recommendations in the studies and this ETA will provide the information that staff needs to write the conditions for the Mitigated Negative Declaration.
