TENTATIVE MAP (TM) and a NEIGHBORHOOD DEVELOPMENT PERMIT (NDP) for the construction of four light industrial warehouse buildings totaling 89,750 square feet on a 5.35-acre parcel previously approved for a laydown area as part of the Nancy Ridge Business Park, located at 5909 Nancy Ridge Drive (Proposed Project). The Proposed Project also includes vehicular parking and installation of utility infrastructure to City standards. The Proposed Project site is in the IL-2-1 (Industrial-Light) zone of the Mira Mesa Community Plan, Residential Tandem Parking Overlay
Zone, Marine Corps Air Station Miramar Airport Influence Area, Accident Potential Zone 2, Airport Environs Overlay Zone, FM Part 77 Notification Area, Environmentally Sensitive· Lands, and Floodway-100 and Floodplain-100 Zones.
The Nancy Ridge Business Park Project (Approved Project) was approved by the City of San Diego in 2008. The Approved Project proposed the construction of a paved, non-standard access 30-foot-wide driveway and internal 40-foot wide right-of-way with a sidewalk from Nancy Ridge Drive to an outdoor storage area consisting of two graded pad areas. Both pads were proposed to be covered with Class 2 base gravel material. Evaluation of the Approved Project in the adopted MND included grading of approximately 58,000 cubic yards of cut with a maximum cut height of 34 feet and a maximum cut slope height of 34 feet with a maximum cut slope ratio of 2:1. The
Approved Project includes a total fill quantity of approximately 58,000 cubic yards with a maximum fill depth of 36 feet and a maximum fill slope height of 30 feet with a maximum fill slope ratio of 2:1. Due to the topography of the site, the Approved Project includes approximately 2,800 feet of keystone retaining walls to
stabilize the proposed step-down, fiat pad areas, and the non-standard driveway. The retaining walls were approved at a maximum height of 31 feet, to be screened with drought tolerant, native plant species that conform to the City's
Landscape Technical Manual. The Approved Project also includes installation of drainage, including a Modular Wetland System, an underground storage system, and storm drain. The Approved Project includes construction Best Management
Practices (BMPs) and post-construction BMPs consistent with the City of San Diego requirements. In approving the Approved Project, the City also adopted the Nancy Ridge Business Park Mitigated Negative Declaration No. 114358 (adopted MND). The adopted MND determined that, with the incorporation of mitigation measures, the
Approved Project would not result in any significant and unavoidable environmental impacts. Pursuant to Public Resources Code Section 21166 and CEQA guidelines 15162 and 15163, the City has determined that: (1) there is substantial evidence that none of the conditions requiring preparation of a subsequent or supplemental EIR or
subsequent Negative Declaration/Mitigated Negative Declaration exist, and (2) the City will rely on the previous environmental document, which adequately addresses this project.
