State of California – The Resources Agency DEPARTMENT OF PARKS AND RECREATION NOTICE OF AVAILABILITY AND INTENT TO ADOPT AN INITIAL STUDY/MITIGATED NEGATIVE DECLARATION FOR THE PROPOSED UTILITY MODERNIZATION PROJECT, TORREY PINES STATE NATURAL RESERVE Date: July 16, 2019 The California Department of Parks and Recreation (CDPR) has prepared and intends to adopt a Mitigated Negative Declaration for the Torrey Pines Utility Modernization project in compliance with the California Environmental Quality Act (CEQA) and State CEQA Guidelines. CDPR is the lead agency for the proposed project under CEQA. PROJECT LOCATION: Torrey Pines State Natural Reserve, San Diego, CA DESCRIPTION OF THE PROPOSED PROJECT: This Project proposes to upgrade the aging utilities infrastructure at Torrey Pines State Natural Reserve by installing replacement underground electric, sewer, domestic water, fire, and telephone utilities to serve this heavily-used 1,300-acre park unit. The 5,726-foot (approximately 1.1 mile) alignment traverses both California Department of Parks and Recreation and City of San Diego property (via encroachment permit). Other project elements include the installation of approximately seven fire hydrants; two master lift stations; three below- ground lift stations; and three water fill stations. PUBLIC REVIEW PERIOD: The Initial Study/Mitigated Negative Declaration is being made available for public review and comment for a period of 30 days, beginning Friday July 19, 2019 and closing on Sunday August 18, 2019. Questions and/or comments regarding the project should be directed to: SSC Environmental Coordinator 2797 Truxtun Road, Barracks 26 San Diego, CA 92106 or by email at: [email protected] The Initial Study/Mitigated Negative Declaration may be reviewed at the following locations during normal business hours or downloaded from the CDPR CEQA Notices website at the following URL: https://www.parks.ca.gov/?page_id=983 San Diego Coast District Southern Service Center California Department of Parks & California Department of Parks and Recreation Recreation 4477 Pacific Coast Hwy. 2797 Truxtun Rd, Barracks 26 San Diego, CA 92110 San Diego, CA 92106 DPR 509B (New 4/2003)(Word 2/11/2005) DRAFT INITIAL STUDY/ MITIGATED NEGATIVE DECLARATION TORREY PINES STATE NATURAL RESERVE UTILITY MODERNIZATION PROJECT July 2019 SCH # State of California DEPARTMENT OF PARKS AND RECREATION MITIGATED NEGATIVE DECLARATION PROJECT: TORREY PINES STATE NATURAL RESERVE – UTILITY MODERNIZATION PROJECT LEAD AGENCY: California Department of Parks and Recreation AVAILABILITY OF DOCUMENTS: The Initial Study for this Mitigated Negative Declaration is available for public review during regular business hours at: • San Diego Coast District Headquarters California Department of Parks & Recreation 4477 Pacific Coast Highway San Diego, CA 92110 .

This document has been prepared in accordance with the California Environmental Quality Act (CEQA), Public Resources Code §21000 et seq., and the State CEQA Guidelines, California Code of Regulations (CCR) §15000 et seq. An Initial Study is conducted by a lead agency to determine if a project may have a significant effect on the environment [CEQA Guidelines §15063(a)]. If there is substantial evidence that a project may have a significant effect on the environment, an Environmental Impact Report (EIR) must be prepared, in accordance with CEQA Guidelines §15064(a). However, if the lead agency determines that revisions in the project plans or proposals made by or agreed to by the applicant mitigate the potentially significant effects to a less-than-significant level, a Mitigated Negative Declaration may be prepared instead of an EIR [CEQA Guidelines §15070(b)]. The lead agency prepares a written statement describing the reasons a proposed project would not have a significant effect on the environment and, therefore, why an EIR need not be prepared. This IS/MND conforms to the content requirements under CEQA Guidelines §15071. 1.2 LEAD AGENCY The lead agency is the public agency with primary approval authority over the proposed project. In accordance with CEQA Guidelines §15051(b)(1), "the lead agency will normally be an agency with general governmental powers, such as a city or county, rather than an agency with a single or limited purpose." The lead agency for the proposed project is DPR. The contact person for the lead agency is: John Justice, Project Manager Southern Service Center California Department of Parks & Recreation 2797 Truxtun Road, Barracks 26 San Diego, CA 92106 (619) 221-4368 All inquiries regarding environmental compliance for this project, including comments on this environmental document should be addressed to: - 1 - Utility Modernization Project IS/MND Torrey Pines State Natural Reserve California Department of Parks and Recreation Mike Yengling, Environmental Coordinator Southern Service Center California Department of Parks & Recreation 2797 Truxtun Road, Barracks 26 San Diego, CA 92106 [email protected] 1.3 PURPOSE AND DOCUMENT ORGANIZATION The purpose of this document is to evaluate the potential environmental effects of the proposed Utility Modernization Project at Torrey Pines State Natural Reserve. Mitigation measures have also been incorporated into the project to eliminate any potentially significant impacts or reduce them to a less-than-significant level. This document is organized as follows: • Chapter 1 - Introduction. This chapter provides an introduction to the project and describes the purpose and organization of this document. • Chapter 2 - Project Description. This chapter describes the reasons for the project, scope of the project, and project objectives. • Chapter 3 - Environmental Setting, Impacts, and Mitigation Measures. This chapter identifies the significance of potential environmental impacts, explains the environmental setting for each environmental issue, and evaluates the potential impacts identified in the CEQA Environmental (Initial Study) Checklist. Mitigation measures are incorporated, where appropriate, to reduce potentially significant impacts to a less-than-significant level. • Chapter 4 - Mandatory Findings of Significance This chapter identifies and summarizes the overall significance of any potential impacts to natural and cultural resources, cumulative impacts, and impact to humans, as identified in the Initial Study. • Chapter 5 - Summary of Mitigation Measures.
