Lot 98 is approximately coterminous with Assessor Parcel Number (APN) 949-016-006 (Exhibit 3), with the addition of about 5 acres from the adjoining APN 948-15-2-1. Lot 98 encompasses approximately 112 acres, consisting of approximately 33 acres known generally as the Spotorno Flat Area, as well as approximately 81 acres identified as Parcel C in the proposed development plan. The Spotorno Flat Area is described as 33 acres in the HVSP but two of those acres have building constraints and will be added to future Parcel C being proposed as part of the proposed project. (Exhibit 3). For the purposes of density calculation, the entire 33 acres is utilized, as it was identified in the original HVSP. The HVSP Environmental Impact Report, certified by the City in 1998 (State Clearinghouse [SCH] No. 97032034, certified June 16, 1998) (1998 HVSP FEIR), evaluated the potential environmental impacts associated with construction of 22 dwelling units in the Spotorno Flat Area. The proposed project consists of a request for a Planned Unit Development (PUD) to create 22 single-family residential lots for semi-custom homes with an accessory dwelling unit on each lot and related on- and off-site improvements, consistent with the number of dwelling units evaluated in the 1998 HVSP FEIR. Development activity would be limited to an approximately 31-acre portion of the Spotorno Flat Area; the remaining 2 acres comprising the 33-acre Spotorno Flat Area are located within a defined 50-foot setback from the Verona Fault. Accordingly, these 2 acres are considered undevelopable and are therefore proposed to be dedicated as permanent agricultural open space, along with the remainder of Lot 98 (i.e., the approximately 81-acre “Parcel C”) (Exhibit 3). Lots could be sold to a builder or sold individually, and each house would be constructed by the owner under the design guidelines of the PUD. The Spotorno Family would retain the remaining approximately 81 acres (Parcel C plus the two undevelopable acres of the Spotorno Flat Area), which would be dedicated and zoned Agricultural and Open Space (A/OS). This Initial Study/Consistency Checklist and attached supporting documents have been prepared to determine whether and to what extent the 1998 HVSP FEIR addresses the potential impacts of the proposed project.1 Where appropriate, this checklist identifies current Best Management Practices (BMPs) that would enhance the effectiveness of mitigation measures from the 1998 HVSP FEIR that are applicable to the proposed project. The following Consistency Checklist has been prepared pursuant to State California Environmental Quality Act (CEQA) Guidelines Section 15182(a) (Projects 1 Technical studies and preliminary environmental review were conducted in 2018 to evaluate a higher density 39-unit development on the same site. To the extent the 2018 data and analysis remain relevant, it is provided for informational purposes to aid in the analysis of the proposed project.
