Sumner Place Residential Development

The Sumner Place Residential Development is a for-sale multi-family townhome project in Eastvale, California, proposing 159 units across approximately 7.54 net acres, yielding a net density of 21.1 dwelling units per acre. The development requires several entitlements including a General Plan Amendment to reclassify the land from Commercial Retail to Multi-Family-Low-Moderate zoning, a zoning change from Heavy Agriculture (A-2-5) to General Residential (R-3), approval through Major Development Review, and submission of Tentative Tract Map 38032 for condominium conversion. Site improvements encompass ornamental landscaping, drive aisles, pedestrian walkways, and trash enclosures, while off-site enhancements to Schleisman Road, Sumner Avenue, and Orange Street are necessary to accommodate new gated entrances. The project’s performance period spans from March 2026 through March 2028, with distinct phases including demolition, site preparation, grading, trenching, building construction, architectural coating, and paving, all occurring at the designated property located at 7080 Sumner Avenue with APN 152-040-001. Environmental compliance is governed by CEQA and Co-Permittee requirements, with key deliverables including Drainage Management Area classifications, Design Capture Volume calculations, and stormwater management plans aligned with the WQMP Guidance Document and TR-55 standards. Earthwork and grading must meet ASTM D1557-91 compaction standards, with fill material limited to less than 5% organic matter and lift thicknesses capped at eight inches, all subject to acceptance by the Geotechnical Consultant. Special conditions exclude assessments for asbestos, radon, methane, radionuclides, earthquakes, floods, and endangered species, and prohibit PCB testing or analysis of air, water, and building materials. The environmental assessment report is restricted to use by SC Sumner, LLC and Southwood LTD and is valid for 180 days from site reconnaissance. No contract value, pricing structure, procurement evaluation factors, FAR clauses, or federal acquisition terms are specified, and no payment, invoicing, or contracting officer details are provided. All administrative and technical coordination is managed through the City of Eastvale, with primary contacts in planning and environmental review roles.
