Client: Kimley Horn / City of Rialto
Project Description:
The Rialto Fulfillment Center planned over 2.2 million square feet of warehouse space in two state-of-the-art logistics buildings, redeveloping 121.8 acres west of Cactus Avenue. Its scale, high truck volumes, and adjacency to sensitive receptors demanded careful evaluation of noise and vibration.
Services Provided: Noise & Vibration Impact Analysis, Air Quality, GHG & Health Risk Assessment
Solution:
Entech used a combination of FHWA TNM, FTA vibration criteria, and on-site measurements to model construction noise, operational truck traffic, loading dock activity, and rooftop mechanical equipment. We pinpointed areas with exceedances and proposed targeted mitigations, such as truck routing protocols, upgraded dock door seals, sound barriers, and construction hour limitations.
We also developed a robust CEQA-compliant air quality and health risk assessment using CalEEMod, EMFAC, and AERMOD to evaluate criteria pollutants, GHGs, and toxic air contaminants from both construction and operation. Our modeling incorporated worst-case mobile-source TAC exposure and compared impacts to OEHHA health risk guidelines. Best practices for idling restrictions, fleet modernization, and building efficiency were incorporated.
Benefits:
Our analysis enabled the City to move forward with a transformative economic development project with confidence that community noise and vibration standards would be met — preserving residential quality of life and protecting adjacent sensitive habitat. Entech’s precise, transparent analysis assured the City and stakeholders that even at its large scale, the project could meet stringent regional and state standards — mitigating health risks while enabling economic investment and job creation.
