Fontana Walnut Residential Project

The Fontana Walnut Residential Project, managed by the City of Fontana under Master Case No. 24-0060, is a comprehensive development effort to construct a 393-unit multi-family residential community on approximately 30.99 gross acres. The development consists of 103 detached cluster units, 113 detached motor court units, and 177 attached townhomes, supported by 786 garage parking spaces and associated infrastructure including drive aisles, landscaping, and utilities. To facilitate this, the project requires a General Plan Amendment to change land use from Multi-Family Medium/High to Multi-Family Residential, a zoning change from R-4 to R-3, the creation of a Planned Unit Development, and the subdivision of 35 parcels via Tentative Tract Map No. 20712. The scope also includes the upzoning of an additional 56.1 acres and the abandonment of a portion of Knox Avenue. The project is subject to rigorous environmental and technical compliance standards as detailed in a Mitigated Negative Declaration and a Mitigation Monitoring and Reporting Program. Key technical requirements include a Preliminary Water Quality Management Plan adhering to Regional Water Quality Control Board standards, a Preliminary Sewer Study requiring a 960-foot upgrade of the sewer main to 10 inches, and a Phase I Environmental Site Assessment. Traffic impacts have been evaluated through a VMT Screening Analysis and a Traffic Impact Assessment, which recommend specific circulation improvements to maintain Level of Service C standards. Additionally, the project must comply with biological and archaeological guidelines, including the management of potential impacts on burrowing owls and the preservation of cultural resources, as well as adhering to EPA Tier 4 emission limits for construction equipment.
