The Highland Grove 5 residential development project, managed by Adkan Engineers and overseen by the Riverside County Planning Department, involves a comprehensive suite of land use applications for a 36.55-acre property in the Victoria Grove community of the Lake Mathews/Woodcrest Area Plan. The project requires a General Plan Amendment, Change of Zone, Tentative Tract Map, and Agricultural Preserve Diminishment to facilitate the construction of 73 single-family detached residential units on minimum 10,000 square-foot lots. The development plan also incorporates 0.73 acres for a park, 1.87 acres for detention and water quality basins, and 5.90 acres dedicated to slopes and open space. Site access will be provided through proposed off-site roadways connecting to Dry Creek Lane and El Sobrante Road, with secondary emergency vehicle access via an easement through Tract Map No. 38605. Extensive technical studies and environmental assessments have been conducted to ensure compliance with California Environmental Quality Act (CEQA) guidelines and regional standards. Key evaluations include geotechnical investigations for soil stability, a focused traffic assessment for trip generation, a sewer feasibility analysis for the Western Municipal Water District, and a preliminary hydrology study for stormwater management. Environmental compliance is addressed through biological resource assessments, including studies on the Crotch's bumble bee, cultural resource monitoring, air quality and greenhouse gas impact analyses, and noise impact modeling. Additionally, the project includes a Water Quality Management Plan to meet Regional Board Order No. R8-2010-0033 and a fire behavior report to establish wildfire risk mitigation and defensible space criteria. The development is subject to various regulatory requirements, including OSHA safety standards for excavations and specific insurance mandates for liability and pollution coverage.
