Client: Kimley Horn / City of Fontana
Project Description:
The El Paseo development encompassed 241 medium-density residential units over 21.9 acres at Citrus and Oleander in Fontana. Designed as a transit-accessible, family-oriented community, it featured 131 detached townhomes, 110 cluster homes, recreational amenities, and landscaped open space. Proximity to major roadways and neighboring residential areas made it critical to evaluate air quality and GHG impacts in detail.
Services Provided: Air Quality & GHG Impact Analysis
Solution:
Entech performed a rigorous CEQA-compliant assessment using CalEEMod to quantify emissions of ROG, NOx, CO, PM10, PM2.5, TACs, and GHGs. We evaluated construction and operational impacts against SCAQMD regional thresholds, the South Coast AQMP, localized significance thresholds (LSTs), potential for asbestos, and odor concerns. We also assessed regional climate consistency. Where modeling indicated potential hotspots, we recommended enhanced dust control, equipment specifications, and design-phase energy efficiency improvements.
Benefits:
By delivering a technically defensible, agency-ready report, Entech enabled the City to confidently approve the project, demonstrating that it met rigorous air quality, health, and climate standards — while contributing critically needed housing stock to the community.
