Arroyo Mocho Flood Risk Reduction

Zone 7 Water Agency • Alameda County, CA • 2022

Radbridge conducted benefit-cost analysis for Zone 7 Water Agency's flood risk reduction project along Stanley Boulevard between Pleasanton and Livermore, California.

Context: The Arroyo Mocho Flood Risk Reduction Project addresses flood risks along Stanley Boulevard in a critical transportation corridor. Zone 7 Water Agency, with support from Environmental Science Associates (ESA), needed economic justification for flood protection infrastructure investments.

Objectives: Conduct comprehensive benefit-cost analysis over a 50-year period for two project alternatives against a 'No Action' baseline, quantifying benefits including travel time savings, GHG reductions, and infrastructure protection to support project approval and funding decisions.
