Document Description
The Slatten Ranch Townhomes Project (proposed project) would consist of a Vesting Tentative Subdivision Map that would subdivide the project site into 17 lots for residential uses, each of which would contain one townhome building and associated landscaping. Each proposed townhome building would consist of either “Row Townhomes” units (55 units) or “Back to Back” (B2B) units (74 units) containing between five and 10 units, for a total of 129 units. Three Row Townhome floorplan types would be offered with two- and three-bedrooms, ranging in size from 1,432 to 1,791 square feet (sf). Two B2B floorplans are offered: a two-bedroom, 1,293-sf plan and a three-bedroom, 1,414-sf plan. All units would have at least one private deck of 70 sf, a storage area of at least 250 cubic feet, and an attached two-car garage. The Row Townhome buildings would front Slatten Ranch Road, Wicklow Way, and Empire Avenue, with units within each building designed in a side-by-side layout. The B2B buildings would be sited generally in the central portion of the project site, with units within each building designed in a side-by-side and back-to-back to layout.
Additionally, 13 separate parcels are proposed for the internal roadway network (Parcels A-J), as well as private common areas (Parcels K and L). The proposed project would include 0.34-acre of common open space located north of the gated entry at Parcel K. A central common area would provide amenities for both adults and children including a bocce court and children’s play area. Benches would be located throughout the common space, along with picnic tables centrally located between the bocce and children’s play area. A second smaller common open space area (approximately 5,200 sf) would be located in Parcel M at the north of the project site. The common space area would have a dog park as well as an open activity area for free use. Parcel M would also contain a bio-retention area. Primary access to the project site would be provided by a gated entry from Wicklow Way with a center landscape median. Emergency vehicle access (EVA) would be provided from Slatten Ranch Road at the northwest of the site. All internal roadways would include a five-foot sidewalk and landscaping, and would be privately owned and maintained by a homeowner’s association (HOA). The proposed project would require the City’s approval of a Vesting Tentative Subdivision Map for condominium purposes and Design Review.

Type, Section or Code
PRC Section 21083.3/CEQA Guidelines Section 15183
Reasons for Exemption
Pursuant to Section 21083.3 of the Public Resources Code and Section 15183 of the CEQA Guidelines, where a project is consistent with the use and density established for a property under an existing general plan or zoning ordinance for which the city has already certified an EIR, additional environmental review is not required “except as might be necessary to examine whether there are project-specific significant effects which are peculiar to the project or its site.” The City previously prepared and certified the Antioch Housing, Environmental Hazards, and Environmental Justice Elements Project Environmental Impact Report (Housing Element EIR) (SCH 2021110146), which established the use and density for this property and from which the City can streamline review pursuant to Sections 15168 and 15183 of the CEQA Guidelines. The proposed project is consistent with the General Plan land use designation of Regional Retail/Employment Generating Lands and zoning designation of R-25. Through a Section 15183 Consistency Memorandum, the City determined that the proposed project would not result in a significant impact that: (1) is peculiar to the project or the project site; (2) was not identified as a significant effect in the Housing Element EIR; or (3) are previously identified significant effects, which as a result of substantial new information that was not known at the time that the Housing Element EIR was certified, are determined to have a more severe adverse impact than discussed in the Housing Element EIR. Therefore, based on Section 15183, further environmental review is not required for the proposed project.
