Mill Creek Single Family Residential (PLN23-00439)

The Mill Creek Single Family Residential project (PLN23-00439) is a land development initiative in Placer County, California, near Roseville. The project involves the development of a 322-lot detached single-family residential subdivision on approximately 65 acres, including the creation of five parks and one paseo trail. The scope of work encompasses the demolition of existing onsite structures and significant infrastructure improvements to PFE Road, Antelope Road, and the intersections of PFE Road/Cook Riolo Road and Cook Riolo Road/Vineyard Road. The project was approved by the Placer County Board of Supervisors on October 7, 2025, following the completion of a Final Environmental Impact Report (EIR) in July 2025. Performance is governed by strict environmental and regulatory standards, including CEQA, the 2022 California Title 24 Building Energy Efficiency Standards, and CALGreen. Key operational requirements include adherence to the CARP and PCCP frameworks, which mandate specific windows for aquatic resource work, the installation of wildlife escape ramps in trenches, and the implementation of comprehensive erosion and sediment control measures. Construction activities are subject to on-site inspections by Placer County and PG&E, with a particular focus on stormwater management and the protection of biological and cultural resources. Project administration is led by the Placer County Community Development Resource Agency, with Meghan Schwartz serving as the primary point of contact.
