What is Green Infrastructure?
Urban development has traditionally involved replacing natural landscapes with impervious pavement and buildings, sometimes called “Gray Infrastructure.” Storm runoff drains directly into local waterways, causing erosion and impacting riparian habitats and the Bay.
We are one of many Bay Area communities adopting new methods to reverse this historic pattern by shifting to the use of Green Infrastructure (GI). GI reduces the impact of urban development on waterways by mimicking nature; using plants, soils, and pervious surfaces to collect stormwater.
This method allows rainwater to soak and filter into the ground, reducing the quantity of water and pollutants flowing into local creeks.
We have used GI in the public right-of-way on several projects over the last few years and are in the planning stages for many more.
We have prepared a comprehensive GI Plan to guide the siting, implementation, tracking, and reporting of GI projects over the next several decades. Development of the GI Plan is required by our Municipal Regional Stormwater National Pollutant Discharge Elimination System Permit.
The GI Plan describes our methodology to identify and prioritize areas for implementing GI, and estimates targets that will be addressed by GI through2040. The Plan includes maps of prioritized areas and potential project opportunities; and lays out our GI implementation strategy.

In 2019, Public Works staff will install improved safety and Green Infrastructure elements in the intersections of:
- 4th Avenue and Fremont Street
- 5th Avenue and Delaware Street
- 9th Avenue and Delaware Street
Improvements include: Pedestrian crosswalks, ADA-compliant ramps, and curb extensions that include Green Infrastructure for stormwater management to reduce pollutants flowing to the bay, creating a healthier environment for everyone.
Work timeline: Work is scheduled to begin in fall 2019 and conclude by the end of the year. Residents in the area can expect to receive mailed construction notices in advance of the work commencing.
