CASE NAME: OCEAN BLUFF APPLICANT: CATELLUS RESIDENTIAL GROUP. INC. ADDRESS AND PHONE NUMBER OF APPLICANT: 5 PARK PLAZA. SUITE 400. IRVINE. CA 92614 DATE EIA FORM PART I SUBMITTED: NOVEMBER 26. 1997 PROJECT DESCRIPTION: The proposed project is a Tentative Map revision, hillside development permit amendment, and coastal development permit to permit: 1) building placement and architectural design of single family units on each single family lot; 2) grading of off-site Poinsettia Lane to the full width right-of-way between Aviara Parkway and Blackrail Road; 3) changes to pad grades to accommodate a sewer realignment to the north resulting from the final design of Blackrail Road; and 4) the conversion of the former affordable housing site to 4 single family lots. Approval of the proposed changes would result in the extension of Poinsettia Lane from its existing terminus at Aviara Parkway to Blackrail Road, increase the number of single family residential lots from 93 to 96, and reduce the total number of units from 108 to 96. SUMMARY OF ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The summary of environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact," or "Potentially Significant Impact Unless Mitigation Incorporated" as indicated by the checklist on the following pages. |^[ Land Use and Planning | | Population and Housing | | Geological Problems Q Water [X] Air Quality [><3 Transportation/Circulation [ [ Public Services [X] Biological Resources | | Utilities & Service Systems | | Energy & Mineral Resources | | Aesthetics | | Hazards | | Cultural Resources I I Noise I I Recreation Mandatory Findings of Significance Rev. 03/28/96 DETERMINATION.

Therefore, a Notice of Prior Compliance has been prepared. Planner Signature ^ I / Date IL Planning DirectorVSignafere Date Rev. 03/28/96 w ENVIRONMENTAL IMPACTS STATE CEQA GUIDELINES, Chapter 3, Article 5, Section 15063 requires that the City conduct an Environmental Impact Assessment to determine if a project may have a significant effect on the environment. The Environmental Impact Assessment appears in the following pages in the form of a checklist. This checklist identifies any physical, biological and human factors that might be impacted by the proposed project and provides the City with information to use as the basis for deciding whether to prepare an Environmental Impact Report (EIR), Negative Declaration, or to rely on a previously approved EIR or Negative Declaration. • A brief explanation is required for all answers except "No Impact" answers that are adequately supported by an information source cited in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved. A "No Impact" answer should be explained when there is no source document to refer to, or it is based on project-specific factors as well as general standards. • "Less Than Significant Impact" applies where there is supporting evidence that the potential impact is not adversely significant, and the impact does not exceed adopted general standards and policies. • "Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less Than Significant Impact." The developer must agree to the mitigation, and the City must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level. • "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant. • Based on an "EIA-Part II", if a proposed project could have a potentially significant effect on the environment, but all potentially significant effects (a) have been analyzed adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigated Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed project, and none of the circumstances requiring a supplement to or supplemental EIR are present and all the mitigation measures required by the prior environmental document have been incorporated into this project, then no additional environmental document is required (Prior Compliance). • When "Potentially Significant Impact" is checked the project is not necessarily required to prepare an EIR if the significant effect has been analyzed adequately in an earlier EIR pursuant to applicable standards and the effect will be mitigated, or a "Statement of Overriding Considerations" has been made pursuant to that earlier EIR. • A Negative Declaration may be prepared if the City perceives no substantial evidence that the project or any of its aspects may cause a significant effect on the environment. Rev. 03/28/96 • If there are one or more potentially significant effects, the City may avoid preparing an EIR if there are mitigation measures to clearly reduce impacts to less than significant, and those mitigation measures are agreed to by the developer prior to public review. In this case, the appropriate "Potentially Significant Impact Unless Mitigation Incorporated" may be checked and a Mitigated Negative Declaration may be prepared. • An EIR must be prepared if "Potentially Significant Impact" is checked, and including but not limited to the following circumstances: (1) the potentially significant effect has not been discussed or mitigated in an Earlier EIR pursuant to applicable standards, and the developer does not agree to mitigation measures that reduce the impact to less than significant; (2) a "Statement of Overriding Considerations" for the significant impact has not been made pursuant to an earlier EIR; (3) proposed mitigation measures do not reduce the impact to less than significant, or; (4) through the EIA-Part II analysis it is not possible to determine the level of significance for a potentially adverse effect, or determine the effectiveness of a mitigation measure in reducing a potentially significant effect to below a level of significance. A discussion of potential impacts and the proposed mitigation measures appears at the end of the form under DISCUSSION OF ENVIRONMENTAL EVALUATION.

Earlier analyses may be 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 on attached sheets: a) Earlier analyses used. Identify earlier analyses and state where they are available for review. 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. . c) Mitigation measures. For effects that are "Less than Significant with Mitigation Incorporated," describe 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. Rev. 03/28/96 c o DISCUSSION OF ENVIRONMENTAL EVALUATION The proposed tentative map revision, hillside development permit amendment, and coastal development permit are required due to changes in the Ocean Bluff subdivision which involve grading Poinsettia Lane to its full width right-of-way instead of half width between Aviara Parkway and Street A (Reach I), additional grading (with partial improvements) of Poinsettia Lane to its full width right-of-way between Street A and Blackrail Road (Reach II), minor pad grade changes and sewer realignment due to the final design of Blackrail Road, the deletion of a 16 unit affordable housing apartment project on Lot 93, and the subdivision of the affordable housing lot into four additional single family lots. These changes increase the total number of single family lots from 92 to 96 and reduce the total number of approved units from 108 to 96. (the Ocean Bluff project received City Council approval to satisfy its 16 unit inclusionary housing requirement at an off-site location. Therefore, the previous environmental impact assessment performed for the Ocean Bluff project dated September 18, 1995 applies to the all items except for the following additional discussion provided for Items la, Ib, and Id. (Land Use), lib (Population/Housing), Vila and VIIc (Biological Resources), and Xa (Noise). la. The proposed revision to the approved tentative map would result in fewer overall units in that the applicant has received approval to purchase credits to satisfy the project's affordable housing at an off-site location and is proposing to subdivide the on-site affordable housing lot into four additional single family lots. This revision reduces the project density from 3.6 du's/acre to 3.2 du's/acre which is consistent with the growth control point of 3.2 du/acre for the site's RLM General Plan designation. Ib. The approved Tentative Map for the Ocean Bluff project received approval of a Coastal Development Permit from the California Coastal Commission. The Commission has indicated that the proposed design changes and the subdivision of the affordable housing site into four additional single family lots is consistent with the approved Coastal Permit. The proposed tentative map revision includes a Hillside Development Permit Amendment and Coastal Development Permit for the addition of residential units on each lot and the addition of an off- site segment of Poinsettia Lane (Reach II), a circulation element roadway, between Street "A" and Black Rail Road. The applicant has included the additional Poinsettia Lane road segment at the City's request. This segment of the Poinsettia Lane extension will connect Poinsettia Lane to Black Rail Road thereby enabling access through the majority of the Zone 20 Specific Plan area via Poinsettia Lane. The Reach II extension is consistent with relevant coastal policies regarding dual criterion slopes and agricultural lands in that no dual criterion slopes will be impacted and impacts to non-prime agricultural lands will be mitigated as discussed below. Id. The project will impact non-prime coastal agricultural resources and in accordance with the Zone 20 PEIR mitigation measures, the project will be conditioned to pay agricultural mitigation fees for the additional 2.94 acres of non-prime agricultural land disturbed by Reach II of the Poinsettia Lane extension. Additionally, to mitigate potential impacts to existing infrastructure including access roads resulting from the grading and construction of Poinsettia Lane, an infrastructure improvement plan shall be submitted to the Planning and Engineering Departments for approval prior to the issuance of a grading permit. The improvement plan shall show the temporary road connections required in order to maintain continued agricultural use of adjacent properties impacted by this development. lib. As specified by the Zone 20 PEIR, the development of projects including transportation 9 Rev. 03/28/96 routes, public services, and land uses within the Zone 20 planning area is not growth inducing since the area has been previously planned and designated for residential development by the City's General Plan, Growth Management Program, and Zone 20 LFMP. Although the Poinsettia Lane Reach II extension will provide access to undeveloped parcels within Zone 20, it is a planned east-west circulation arterial and development already exists to the east, west, north, and south of Zone 20 properties; therefore, urbanization is inevitable. VIIa,c. The implementation of the Zone 20 Specific Plan PEIR is based on future site specific biological survey studies that focus on the impacts created by individual subsequent development projects. These additional studies are required to consider the baseline data and biological open space recommendations of the PEIR and provide more detailed and current resource surveys plotted at the tentative map scale for each property. The range of future mitigation options include the purchase of similar sensitive habitat off-site. Biological impacts were previously identified and mitigation approved from the full width right-of-way of Poinsettia Lane Reach I, however, the project now consists of additional off-site grading to construct Poinsettia Lane Reach II. To satisfy the EIR requirements, field surveys conducted by Natural Resource Consultants over the 2.94 acres proposed for disturbance by grading of Poinsettia Lane Reach II between Street A and Black Rail Road revealed that .35 acres of disturbed and California sagebrush-dominated coastal sage scrub (CSS) habitat and .45 acres of southern maritime chaparral (SMC) would be disturbed. Although the California gnatcatcher was not observed at the site, disturbance to CSS and SMC habitat are considered significant and therefore mitigation is required. The applicant has proposed to mitigate the identified .35 acres of CSS through the purchase of credits at a 2:1 ratio in an off-site mitigation bank which would require approval of a 4d Habitat Loss Permit by the City of Carlsbad with concurrence from the USFWS. Proposed mitigation for the disturbance to .45 acres of SMC habitat consists of the purchase of credits at a 1:1 ratio in an off-site habitat mitigation bank or revegetation onsite at an off-site location. Any revegetation plan must be in accordance with the Zone 20 Specific Plan and approved by the responsible agencies (USFWS and/or CDFG). NCCP/HMP. 4D RULE The proposed Poinsettia Lane Reach II extension is located at the eastern edge of Linkage Planning Area F (LPA) as defined by the City's draft Habitat Management Plan (HMP) dated December 1, 1997. Although disturbance to .35 acres of CSS habitat in this LPA will result from implementation of the project, it will not preclude connectivity between core planning areas or preclude the preservation of CSS habitat in that the area proposed for disturbance is isolated and surrounded by existing development and/or agricultural activity. Moreover, this project will result in the preservation of .35 acres of high quality CSS habitat in an off-site habitat mitigation bank. Since completion of a subregional NCCP/HMP has not occurred, the City may have to authorize this project to draw from the City's 5% CSS take allowance (4d rule). The take of .35 acres of CSS habitat will not exceed the 5% allowance, nor jeopardize the HMP since it is located outside the HMP core and linkage planning areas, makes no contribution to the overall preserve system, and will not significantly impact the use of habitat patches as archipelago or stepping stones to surrounding core planning areas. Since mitigation for the habitat loss will result in the preservation of equal or better habitat in an off-site location, the project will not appreciably reduce the likelihood of the survival and recovery of the gnatcatcher. The habitat loss is incidental to otherwise lawful activities. The development of Reach II of the Poinsettia 10 Rev. 03/28/96 Lane extension is a legal development which is consistent with the City's General Plan Circulation Element and all required permits will be obtained. Xa. The Zone 20 PEIR noise mitigation included a requirement that all projects within 500 feet of the Poinsettia Lane alignment prepare a noise study in accordance with the General Plan Noise Element. A noise study was previously prepared for the Ocean Bluff project, and mitigation imposed for lots abutting the roadway thereby ensuring that noise levels would not exceed the 60 dBA CNEL standard. The proposed tentative map revision which proposes off- site grading of the entire Poinsettia Lane Reach II right-of-way and partial improvement would result in noise impacts to the adjacent parcels along the southern right-of-way boundary. Noise impacts to these parcels resulting from the roadway will be analyzed and mitigated as part of the future entitlement process required to develop these parcels.
