IWLZMIYLER Planning Director I 11 PC RES0 NO. 4695 -3- - MITIGATED NEGATIVE DECLARATION Project AddressLocation: Located just north of the Batiquitos Lagoon and crossing underneath the 1-5 Freeway within Local Facilities Management Zone 9 and 19. Project Description: To allow the construction of a water line project within the City’s Coastal Zone. The City of Carlsbad has conducted an environmental review of the above described project pursuant to the Guidelines for Implementation of the California Environmental Quality Act and the Environmental Protection Ordinance of the City of Carlsbad. As a result of said review, the initial study (EIA Part 2) identified potentially significant effects on the environment, but (1) revisions in the project plans or proposals made by, or agreed to by, the applicant before the proposed negative declaration and initial study are released for public review would avoid the effects or mitigate the effects to a point where clearly no significant effect on the environment would occur, and (2) there is no substantial evidence in light of the whole record before the City that the project “as revised” may have a significant effect on the environment. Therefore, a Mitigated Negative Declaration is hereby issued for the subject project. Justification for this action is on file in the Planning Department. A copy of the Mitigated Negative Declaration with supportive documents is on file in the Planning Department, 2075 Las Palmas Drive, Carlsbad, California 92009. Comments from the public are invited. Please submit comments in writing to the Planning Department within 30 days of date of issuance. If you have any questions, please call Jason Martin in the Planning Department at (760) 438-1161, extension 4515.

(To be completed by the Lead Agency) 0 I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. IXI 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 NEGATIVE DECLARATION will be prepared. [7 I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. 0 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 Reportmitigated Negative Declaration is required, but it must analyze only the effects that remain to be addressed. 0 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 voided 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. %G P(""lG14 Piker Signature Date I ./zz/sGi Date 2 Rev. 03128196 0 e 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. 0 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. 0 “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. 0 “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. 0 “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect is significant. 0 Based on an “EIA-Part 11”, if a proposed project could have a potentially significant effect on the environment, but & 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). 0 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. 0 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. 3 Rev. 03128/96 0 a 0 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. 0 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 I1 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. Particular attention should be given to discussing mitigation for impacts which would otherwise be determined significant. 4 Rev. 03128196 0 Issues (and Supporting Information Sources).

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. 10 Rev. 03/28/96 e 0 DISCUSSION OF ENVIRONMENTAL EVALUATION I. PROJECT DESCRIPTION/ENVIRONMENTAL SETTING The proposed project involves a request by the CMWD for a CDP to allow the installation of an potable water pipeline. The pipeline would complete a important link in the water delivery system and connect two existing water pipeline stubs. The pipeline will span a distance of approximately 780 feet and be entirely underground. The two existing stubs are located on either side of the 1-5 Freeway, approximately 400 feet north of the Batiquitos Lagoon shoreline. The stub on the west side of the Freeway is located in “Area C” of the Poinsettia Shores Master Plan area. Area C is currently undeveloped but is being prepared for a 85 unit residential development previously approved under CT 98-06. Surrounding uses are either vacant with pending residential, or developed residential. The nearest developed homesites are approximately 180 feet from the connectiodconstruction site. The stub on the east side of the Freeway is in a developed area of the Aviara community. Specifically, the connection would occur in an graded and landscaped, open space lot which is situated in between the Lagoon and the single family neighborhood known as Azure Cove. The connectiodconstruction site is in very close proximity to homesites and would be immediately adjacent to the home located at 880 Piovana Court. This site is the primary construction staging area for the project. Installation of the underground water pipeline is proposed to be conducted via a directional drilling method, which eliminates the need for open trenching. Use of this method will enable the installation to occur under the Freeway with no disruption to traffic flow. The method is also considered to be, in some respects, environmentally friendly since it involves little disruption to topography and surface vegetation. For logistical purposes the drilling activity, the primary construction staging area, will occur on the east side of the Freeway. Construction staging will necessitate the temporary removal of a relatively immature street tree and other introduced landscape materials. The tree will be re-planted, and other shrub and ground cover materials will be replaced, after the project has been completed. A subgrade utility vault, with a surface area of 48 square feet, is also proposed and will be installed adjacent to the pipeline connection in the open space area. Pipeline and vault installations would occur in existing easements when outside of the Freeway right of way. Installation under the Freeway (in the right of way), will require an encroachment permit from Caltrans. 11 Rev. 03/28/96 e 0 11. ENVIRONMENTAL, ANALYSIS B.

Air Quality a) The implementation of subsequent projects that are consistent with and included in the updated 1994 General Plan will result in increased gas and electric power consumption and vehicle miles traveled. These subsequently result in increases in the emission of carbon monoxide, reactive organic gases, oxides of nitrogen and sulfwr, and suspended particulates. These aerosols are the major contributors to air pollution in the City as well as in the San Diego Air Basin. Since the San Diego Air Basin is a “non-attainment basin”, any additional air 12 Rev. 03128196 0 0 emissions are considered cumulatively significant: therefore, continued development to buildout as proposed in the 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 variety of mitigation measures are recommended in the Final Master EIR. These include: 1) provisions for roadway and intersection improvements prior to or concurrent with development; 2) measures to reduce vehicle trips through the implementation of Congestion and Transportation Demand Management; 3) provisions to encourage alternative modes of transportation including mass transit services; 4) conditions to promote energy efficient building and site design; and 5) participation in regional growth management strategies when adopted. The applicable and appropriate General Plan air quality mitigation measures have either been incorporated into the design of the project or are included as conditions of project approval. Operation-related emissions are considered cumulatively significant because the project is located within a “non-attainment basin”, therefore, the “Initial Study” checklist is marked “Potentially Significant Impact”. This project is consistent with the General Plan, therefore, the preparation of an EIR is not required because the certification of Final Master EIR 93-01, by City Council Resolution No. 94-246, included a “Statement Of Overriding Considerations” for air quality impacts. This “Statement Of Overriding Considerations” applies to all subsequent projects covered by the General Plan’s Final Master EIR, including this project, therefore, no further environmental review of air quality impacts is required. This document is available at the Planning Department. b) No Impact c) No Impact d) No Impact TransportatiodCirculation a) No impact, see referenced sources for discussion.. b) No Impact, see referenced sources for discussion. c) No impact, see referenced sources for discussion. d) No impact, see referenced sources for discussion. e) No Impact, see referenced sources for discussion f, No Impact, see referenced sources for discussion Biological a) No Impact During the public comment period on this project, specifically at the Planning Commission public hearing, an issue was raised regarding the project’s construction noise and its potential to impact California Coastal Gnatcatcher. The item was continued to allow additional investigation. As a result of that research it is not expected that the Gnatcatcher would occupy the vegetation area in the immediate vicinity of the construction site. The area is small and of a less than high quality. The area is approximately ?4 acre in size and is coastal sage scrub interspersed with, or disturbed by, introduced vegetation species. The Gnatcatcher typically occupies large undisturbed areas of coastal sage scrub. Additionally, it is expected that the high levels of Freeway noise experienced in the project area (calculated at between 62 and 70 decibels in previously prepared noise studies) have driven the Gnatcatcher from the area. 13 Rev. 03128196 0 0 b) No impact, see referenced sources for discussion. c) No impact, see referenced sources for discussion. d) No impact, see referenced sources for discussion. e) No impact, see referenced sources for discussion.

Noise a) As indicated in the project description section, the primary construction staging area is on the east side of the Freeway and in close proximity to residential uses. The CMWD has indicated that given the topography of the project site and the technological requirements of the directional drilling construction technique, staging is necessary on the east side of the Freeway. Construction will occur over a six week period. Residential uses are expected to be temporarily impacted by noise associated with construction activity. The CMWD is proposing to mitigate the temporary noise impacts by limiting construction hours and installing a “noise blanket”. Hours of construction activity would be consistent with to those prescribed in the City Municipal Code. Construction activity would be limited to between the hour of 7 AM and dusk, Monday through Friday and between the hour of 8 AM and dusk on Saturdays. No construction activity would be permitted on Sunday. Additionally the CMWD is proposing the installation of a noise blanket to minimize the impacts to the immediately adjacent homesite. The “blanket” is actually a specially designed noise attenuation wall temporarily installed between the noise source and the homes. The wall is 16 feet tall and 80 feet long. According to data provided by the CMWD, the anticipated noise level, with the proposed mitigation, can be brought down to 60 dB (decibels). Staff believes that although the noise would be considered annoying by most people, a 60 dB level is not considered severe. (To assist in illustrating dB, consider the following scenario based on standards fi-om the Noise Element of the City General Plan. An individual standing adjacent to the 1-5 Freeway, at the same grade of the road and with no noise attenuating devices such as landscaping, freestanding masonry block walls, or the exterior wall of a residence, the experienced noise level would be 75 dB). b) No impact, see referenced sources for discussion.
