The Environmental Impact Assessment appears in the followi pages in the form of a checklist. This checklist identifies any physical, biological and hum factors that might be impacted by the proposed project and provides the City with information use as the basis for deciding whether to prepare an Environmental Impact Report (EIR), Negatj Declaration, or to rely on a previously approved EIR or Negative Declaration. a A brief explanati.on is required for all answers except “No Impact” answers that s adequately supported by an information source cited in the parentheses following ea question. A “No Impact” answer is adequately supported if the referenced informati’ sources show that: the impact simply does not apply to projects like the one involved. “No Impact” ansvver should be explained when there is no source document to refer to, it is based on project-specific factors as well as general standards. a “Less Than Sign.ificant Impact” applies where there is supporting evidence that t potential impact .is not adversely significant, and the impact does not exceed adopt general standards and policies. a “Potentially Significant Unless Mitigation Incorporated” applies where the incorporatic of mitigation measures has reduced an effect from “Potentially Significant Impact” to “Less Than Significant Impact.” The developer must agree to the mitigation, and tl City must describe the mitigation measures, and briefly explain how they reduce tl effect to a less than significant level. e “Potentially .Significant Impact” is appropriate if there is substantial evidence that : effect is significant. a Based on an “E1.A-Part 11”, if a proposed project could have a potentially significa! effect on the environment, but & potentially significant effects (a) have been analyzc adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicab standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigatc Negative Declaration, including revisions or mitigation measures that are imposed upc the proposed project, and none of the circumstances requiring a supplement to c supplemental EIR are present and all the mitigation measures required by the pric environmental document have been incorporated into this project, then no addition environmental document is required (Prior Compliance). a When “Potentially Significant Impact” is checked the project is not necessarily requirt to prepare an EIR if the significant effect has been analyzed adequately in an earlier EI: pursuant to applicable standards and the effect will be mitigated, or a “Statement ( Overriding Considerations” has been made pursuant to that earlier EIR. a A Negative Declaration may be prepared if the City perceives no substantial evidence th the project or any of its aspects may cause a significant effect on the environment. 3 Rev. 03/28/96 0 0 If there are one or more potentially significant effects, the City may avoid preparing EIR if there are mitigation measures to clearly reduce impacts to less ban significant, a those mitigation measures are agreed to by the developer prior to public review. In tl case, the appropriate “Potentially Significant Impact Unless Mitigation Incorporate may be checked and a Mitigated Negative Declaration may be prepared. a An EIR must be prepared if “Potentially Significant Impact” is checked, and includi but not limited to the following circumstances: (1) the potentially significant effect 1 not been discussed or mitigated in an Earlier EIR pursuant to applicable standards, a the developer does not agree to mitigation measures that reduce the impact to less th significant; (2) a “Statement of Overriding Considerations’’ for the significant impact h not been made pursuant to an earlier EIR; (3) proposed mitigation measures do not redu the impact to less than significant, or; (4) through the EIA-Part I1 analysis it is I: possible to determine the level of significance for a potentially adverse effect, determine the effectiveness of a mitigation measure in reducing a potentially significe effect to below a level of significance. A discussion of potential impacts and the proposed mitigation measures appears at the end oft form under DISCUSSION OF ENVIRONMENTAL EVALUATION. Particular attentic should be given to discussing mitigation for impacts which would otherwise be deterrnin significant. Issues (and Supporting Information Sources).

XVII. EARLIER ANAL’YSES. There are three sources of earlier analysis referenced above. Source #I is the Maste Environmental Impact Report (MEIR 93-01) for the 1994 General Plan Update. This analysi reviews the potential impacts of developing the City in conformance with the General Plan in th 8 Rev. 03/28/96 * e areas of land use and planning, population and housing, geologic problems, water, air quali transportation and circulation, biological resources, energy and mineral resources, hazards, noi public service, utilities and service systems, aesthetics, cultural resources and recreation. SOU #2 is the “Preliminary Geotechnical Study - Lohf Property”, dated June 25, 1998 and prepared Pacific Soils Engineering, Inc. of San Diego, California. Source #3 is the “Hydrology Study Lohf Property”, dated July 3 1, 1998 and prepared by Hunsaker and Associates. The proposed Lohf Subdivision project involves the subdivision and grading for, and t construction of, 73 single family homes over 36.7 acres, with three open space lots. The site mostly cleared of native vegetation from previous agricultural operations, with the exception some habitat in the southwest comer of the project site. The proposed development WOI encroach into approximately 1.6 acres of native habitat, including the relocation or removal 0. mature oak tree. The proposed habitat removal is proposed to be mitigated by preservation oft. remaining areas of native habitat and by relocating or replacing the mature oak tree. The si may also contain paleontological and archeological resources and appropriate mitigatic measures have been included. With the exception of land use and planning, biological resources and cultural resources, f proposed action, as designed, has no additional impacts not previously analyzed. in the earli environmental review anti no additional review or mitigation measures are necessary with rega to population and housing, geologic problems, water, energy and mineral resources, hazarcl noise, public service, utilities and service systems, aesthetics, and recreation. DISCUSSION OF ENVIRONMENTAL EVALUATION The proposed project has two components: a Zone Change and Local Coastal Progra Amendment to change the zoning designation from Limited Control (L-C) to One Fami Residential (R-1-7,5-00) for two parcels totaling 36.7 acres; and a Tentative Tract Map, Hillsic Development Permit and Coastal Development Permit to allow the subdivision and grading fo and construction of, a 73 unit single family residential development over 29.6 acres, with 7. acres remaining in three open space lots. The property is designated Residential Low Mediu~ Density (EM), which allows for residential uses at densities from 0.0 to 3.2 dwellings p‘ developable acre (ddac) by the City’s General Plan and Growth Management Ordinance. TI subject properties also located within the City’s Coastal Zone. The project site is generally located west of El Camino Real, between Cassia Road and Do\ Lane, within the City’s Coastal Zone. The site is surrounded to the west, north and east b virtually undeveloped property, with the exception of two single family homes on the adjacer lots to the north. These properties are also designated for residential development in the densit range of 0.0 to 3.2 ddac .by the City’s General Plan and Growth Management Ordinance. Sout of the project site is Pavoreal, a 90 unit, single family subdivision at a density of 3.1 ddac The project site also borders the South Carlsbad Library parcel along a small portion of th eastern side, just south of the entry point for Dove Lane onto the subject property. The project site is mostly cleared from previous agricultural operations and contains three sing1 family homes. The homes are currently accessed via a dirt road leading from El Camino Rea’ which lies approximately 200 feet to the west. Future access of the subdivision would be take from Dove Lane, Mimosa Drive, and future Poinsettia Lane, which will traverse the norther portion of the site in an east-west direction. The water, sewer, and storm drain facilit 9 Rev. 03/28/96 0 0 requirements would be met through existing and proposed infrastructure and would be in plz prior to occupancy of any structure. The Zone Change and LlDcal Coastal Program Amendment would bring the zoning designatic of the property into conlormance with the City’s General Plan and Local Coastal Program a the proposed developmlent would conform to all applicable regulations and policies. discussed below, all potential impacts, except for Air Quality and Circulation, will be mitigal to a level of insignificance. LAND USE AND PLANNING As mentioned above, the existing General Plan designation of the subject property is Resident Low Medium (RLM), wlhich, after adjusted in accordance with the City’s Growth Manageme Ordinance, allows a density of 0.0 to 3.2 dwelling units per developable acre. The existi. zoning is Limited Control (L-C), which is a temporary designation given to annexed lands. T appropriate zoning designation to implement the RLM General Plan designation is One Fami Residential (R- 1). Therefore the proposed Zone Change and Local Coastal Program Amendmc to change the zoning of the subject property to R-1 is appropriate and consistent with applicable land use documents. Since the property is within the Coastal Zone, the Local Coas Program Amendment is necessary to maintain consistency between the City’s Zoning Ordinan and the implementing orclinances of the City’s Local Coastal Program. AIR OUALITY: The implementation of subsequent projects that are consistent with and included in the updatr 1994 General Plan will rt:sult in increased gas and electric power consumption and vehicle mil traveled. These subsequently result in increases in the emission of carbon monoxide, reacti. organic gases, oxides of :nitrogen and sulfur, and suspended particulates. These aerosols are t: major contributors to air pollution in the City as well as in the San Diego Air Basin. Since t. San Diego Air Basin is a “non-attainment basin”, any additional air emissions are consider1 cumulatively .significant: therefore, continued development to buildout as proposed in tl updated General Plan will have cumulative significant impacts on the air quality of the region. To lessen or minimize the impact on air quality associated with General Plan buildout, a varie of mitigation measures are recommended in the Final Master EIR. These include: 1) provisiol for roadway and intersection improvements prior to or concurrent with development; 2) measurl to reduce vehicle trips through the implementation of Congestion and Transportation Demx Management; 3) provisions to encourage alternative modes of transportation including ma transit services; 4) condlitions to promote energy efficient building and site design; and participation in regional growth management strategies when adopted. The applicable ar appropriate General Plan air quality mitigation measures have either been incorporated into tl design of the project or are included as conditions of project approval. Operation-related emissions are considered cumulatively significant because the project located within a “non-altainment basin”, therefore, the “Initial Study” checklist is markc “Potentially Significant 1,rnpact”. This project is consistent with the General Plan, therefore, tl preparation of an EIR is riot required because the certification of Final Master EIR 93-0 1, by Ci. Council Resolution No. 94-246, included a “Statement Of Overriding Considerations” for a quality impacts. This ‘“Statement Of Overriding Considerations” applies to all subseque 10 Rev. 03/28/96 a e projects covered by the General Plan’s Final Master EIR, including this project, therefore, further environmental review of air quality impacts is required. This document is available at t Planning Department. In addition to the impacts discussed above, there are a number of occupied single family hom on the southern and northern borders of the project area. To preclude local air quality impacts these residences during grading, a mitigation measure designed to reduce construction-relatl dust and emissions is included. CIRCULATION: The implementation of subsequent projects that are consistent with and included in the updatt 1994 General Plan will result in increased traffic volumes. Roadway segments will be adequa to accommodate buildout traffic; however, 12 full and 2 partial intersections will be severe impacted by regional through-traffic over which the City has no jurisdictional control. The: generally include all fieeway interchange areas and major intersections along Carlsb: Boulevard. Even with the implementation of roadway improvements, a number of intersectiol are projected to fail the City’s adopted Growth Management performance standards at buildout. To lessen or minimize the impact on circulation associated with General Plan buildout, numerot mitigation measures have been recommended in the Final Master EIR. These include : measures to ensure the provision of circulation facilities concurrent with need; 2) provisions 1 develop alternative modes of transportation such as trails, bicycle routes, additional sidewalk pedestrian linkages, and commuter rail systems; and 3) participation in regional circulatic strategies when adopted. The diversion of regional through-traffic fiom a failing Interstate c State Highway onto City streets creates impacts that are not within the jurisdiction of the City t control. The applicable and appropriate General Plan circulation mitigation measures have eithc been incorporated into the design of the project or are included as conditions of project approval Regional related circulation impacts are considered cumulatively significant because of th failure of intersections at buildout of the General Plan due to regional through-traffic, therefort the “Initial Study” checklist is marked “Potentially Significant Impact”. This project i consistent with the General Plan, therefore, the preparation of an EIR is not required because thl recent certification of Fiaal Master EIR 93-01, by City Council Resolution No. 94-246, includec a “Statement Of Overriding Considerations” for circulation impacts. This “Statement 0 Overriding Considerations” applies to all subsequent projects covered by the General Plan’ Master EIR, including this project, therefore, no further environmental review of circulatiol impacts is required. BIOLOGICAL RESOURCES The project site has been reviewed for sensitive biological resources by the project applicant’: biologist, Anita Hayworth, Ph.D., the findings of which are contained in “Biological Resource: Report and Impact Analysis for the Dove Lane Property”, dated May 5, 1998. According to tha study, 28.6 acres of the project site is disturbed or developed due to previous agricultura activities and the existing residential uses. There is one large area of native vegetation remaining in the southwestern portion of the site. This area totals approximately 5.5 acres, has greatlq sloping topography, and contains southern maritime chaparral and a coastal live oak ripariar forest. A California gnatcatcher female with juvenile(s) (Polioptila califomica) was alsc 11 Rev. 03/28/96 e 0 observed in this habitat area, however this was during the late summer and the birds were like dispersing or roaming the vicinity, according to the biological study . With the exception of tl northernmost 0.4 acres of native vegetation, the southwestern portion of the site will remain natural open space and be maintained by the future homeowners association. There is also small area of southern rnaritime chaparral in the northwestern comer of the site, which w remain intact as well. Mitigation for the removal of 0.4 acres of southem maritime chaparral, as well as other, no1 sensitive plant communities (i.e. 1.2 acres of southern mixed chaparral and 0.5 acres ( eucalyptus woodland) would be accomplished through preservation of the remaining 5.5 acres ( southern maritime chapanal. Since a California gnatcatcher was observed on site, the gradir operations are being restricted during the gnatcatcher’s breeding season, from February 1 1 August 3 1 each year. The site also contains a mature coast live oak (Quercus agrifolia), located in the middle of tl disturbeddeveloped area. Since the project cannot be designed around the tree, the applica must mitigate the loss by planting ten (10) coast live oaks within the project open space areas t be preserved. Based upon the information in the biological study, the proposed mitigation measures, 2 generally described abovle and detailed below, will reduce the project’s impacts to biologic; resources to a level of insignificance. L CULTURAL RESOURCIS While the Lohf Subdivision project site does not contain any structures of historical significance there is a prehistoric site located in the area, identified as CA-SDi-8 195. There have been twl previous archeological reconnaissances conducted on site: the ‘‘Draft Historical/Archeologice Survey for the Dove Lane Property”, conducted by Gallegos and Kyle in 1997; and “interir Letter Report of Significance Testing at CA-SDi-8195, Dove LaneLohf Property.. .”, written b: Dayle Cheever and dated September 8, 1997. According to both of these studies, the existin, archeological artifacts and ecofacts. have been heavily disturbed due to agricultural ant residential uses on the project site. In August of 1997, the site was surveyed and determined tl be significantly altered by recent historic land use practices with the result of limited researc, value. The artifacts collected from the site are being analyzed to glean what general informatior is available, the results are expected in the near future. No additional archeological work wa: recommended on the site. There are potentially significant fossil areas of Tertiary and Quaternary Ages within the projec site, therefore, the grading operations of the project are conditioned to be monitored by i qualified paleontologist in case of fossil discovery. These mitigation measures allow thc paleontologist to direct or divert grading operations to facilitate paleontological investigations. 12 Rev. 03/28/96 . 0 e LIST OF MITIGATING MEASURES (IF APPLICABLE) 1. To mitigate fugitive dust and other construction-related air quality impacts, the develol L shall do the following: 4 4 4 4 4 4 4 4 4 Control fugitive dust by regular watering, or other dust prevention measures; Maintain equipment engines in proper tune; Seed and wilter until vegetation is grown; Spread soil binders Wet the area down, sufficient enough to form a crust on the surface with repeat soakings, as necessary, to maintain crust and prevent dust pick-up by the wind; Street sweeping, should silt be carried over to adjacent public thoroughfares; Use water trucks or sprinkler systems to keep all areas where vehicles move dm enough to p:revent dust raised when leaving site; Wet down areas in the late morning and after work is completed for the day; Use of low sulfur fuel (0.5% by weight) for construction equipment. 2. To mitigate the loss of southern maritime chaparral and southern mixed chaparral, t: proposed development shall demonstrate conformance with the recommendations of “ Biological Resources Report and Impact Analysis for the Dove Lane Property, City Carlsbad”, preparled by Anita M. Hayworth and dated May 5, 1998, including, but nl limited to, preservation and maintenance of the existing coastal maritime chaparr habitat. 3. To mitigate the loss of a mature coast live oak, the developer shall either transplant tl mature coast live (oak tree, or plant replacement coast live oak trees at a ratio of 1O:l at location to the satisfaction of the Planning Director. A landscaping plan showing all 02 tree transplanting or replanting shall be submitted to, and approved by, the Plannir. Director prior to issuance of grading permit. 4. To mitigate potential disturbances to the California gnatcatcher, the grading operatior within 100 feet of the proposed open space area will be restricted during the gnatcatchc breeding season, or from February 15 to August 30 each year, unless it can be show through field reconnaissance by a certified biologist that no gnatchatchers are present c the property for two months prior to the start of grading. 5. To mitigate potential paleontological impacts, the developer shall accomplish th following prior to final map approval or issuance of grading permit: 4 A qualified paleontologist shall be retained to perform a walkover survey of the si1 and to review the grading plans to determine if the proposed grading will impac fossil resources A copy of the paleontologist’s report shall be provided to th Planning Director prior to issuance of a grading permit. A qualified paleontologist shall be retained to perform periodic inspections of th site and to salvage exposed fossils. Due to the small nature of some of the fossil present in geologic strata, it may be necessary to collect matrix samples fo 13 Rev. 03/28/96 A a e laboratory processing through fine screens. The paleontologist shall make perioc reports to the Planning Director during the grading process. L The paleontologist shall be allowed to divert or direct grading in the area of exposed fossil in order to facilitate evaluation and, if necessary, salvage artifacts. + All fossils collected shall be donated to a public, non-profit institution with research interest in the materials, such as the San Diego Natural History Museum. + Any conflicts regarding the role of the paleontologist and the grading activities shz be resolved by the Planning Director.
