Horton, and the City of Menifee to guarantee the completion of the required flood control facility improvements associated with County of Riverside Tract Map 37439 by D.R. Horton Los Angeles Holding Company, Inc., located east of Briggs Road and south of Holland Road, in the unincorporated area of the County of Riverside.
DISCUSSION
Tract Map 37439, also known as Canterwood (Project), is a proposed residential development in the unincorporated area of the County of Riverside, just outside the City limits. The Project is located east of Briggs Road and south of Holland Road. While the Project is not located within the City limits, D.R. Horton Los Angeles Holding Company, Inc. (Developer), a California corporation, is required to construct stormwater facility improvements for the Riverside County Flood Control and Water Conservation District (District) that fall within the City limits at the intersection of Briggs Road and Holland Road, as shown in the attached Project Location Map.
The Holland Channel Stage 1 (District Facilities) improvements consist of approximately 370 feet of a 14-foot by 7-foot concrete box, approximately 225 lineal feet of transition structures, associated outlet structures, and an access road. The four-party Cooperative Agreement (Agreement) was accepted by City Council on December 4, 2024. The ownership and ongoing maintenance of the Project improvements are summarized below:
