This effort is intended to provide planning-level regional guidance for placement of green stormwater infrastructure (GSI) in Livermore-Amador Valley. This work, presented in the report “Green Stormwater Infrastructure Planning-level Analysis for Livermore-Amador Valley”, identifies potential GSI locations and quantifies contaminant load and stormwater runoff volume reduction benefits through the application of GreenPlan-IT, a planning tool developed by the San Francisco Estuary Institute and regional partners. Addressing regional challenges to address water quality and flooding concerns requires common sources of information for identifying opportunities for high-priority, multi-benefit stormwater projects. Achieving the goals and requirements of the San Francisco Bay Municipal Regional Stormwater Permit through GSI implementation by cities can also serve stream management goals for flood protection, adequate water supply, and healthy habitats. An intended outcome of this work is to enhance communication and coordination between Zone 7 and the cities of Dublin and Pleasanton.
Uses of the results from this application of GreenPlan-IT include: 1) identifying priority subcatchments and suitable locations for GSI at a multi-jurisdictional scale; 2) supporting Zone 7 and city communication and collaboration to leverage funding for multibenefit projects; and 3) informing future planning efforts, including GSI plans and the Zone 7 Flood Master Plan. Ultimately, the urban greening analysis by the Preparing for the Storm partnership is intended to help enhance stream and watershed resilience, reduce peak flows, and improve water quality.
