High Cube Warehouse Trip Rate Study for Air Quality Analysis

SCAQMD staff is overseeing the development of a study on high-cube warehouse vehicle and truck trip rates for California Environmental Quality Act (CEQA) air quality analyses.  High-cube warehouses attract heavy duty diesel trucks on a daily basis.  Emissions from these trucks produce local and regional air quality impacts that need to be assessed pursuant to CEQA.  This study will provide additional information regarding the number of vehicles (including trucks) that visit these types of facilities.

UPDATE

Draft final results for the Warehouse Truck Trip Study are completed and are lower than current SCAQMD recommended truck trip rates in the California Emissions Estimator Model (CalEEMod).  As an interim measure, staff is recommending truck trip rates from the Institute of Transportation Engineers (ITE) for high cube warehouse projects located in SCAQMD.  Consistent with CEQA Guidelines, an EIR may use a non-default trip rate if there is substantial evidence indicating another rate is more appropriate for the air quality analysis.  Staff will be bringing this item to the SCAQMD Governing Board in the Fall 2014 and anticipates to have a formal policy recommendation on truck trip rates for high cube warehouses based on the study results.

WORKING GROUPS

Two working groups have been convened to provide input to this study.  These include a Stakeholder Working Group (PDF, 126kb) consisting of warehouse developers, environmental groups, and local government transportation and planning staff and a Technical Working Group (PDF, 99kb) consisting of transportation researchers from local universities, two traffic consultants, and a representative from the Southern California Association of Governments (SCAG).
