Green Infrastructure

Green infrastructure (GI) uses plants, soils, and other elements to manage water quality and mimic the natural water cycle by capturing rainwater. Green infrastructure acts as sustainable systems that retain, detain, filter, harvest, infiltrate, and/or evapotranspirate stormwater runoff to create healthier urban environments. Examples of green infrastructure include stormwater planters or bioretention areas, infiltration systems, permeable pavement, green roofs, green walls, green gutters, and stormwater trees.

Green infrastructure provides many benefits such as improving water quality by removing trash and pollutants, reversing urbanization on local creeks and waterways, decreasing the chance of localized flooding, biodiversity and habitat preservation for native plants and animals, traffic calming, and overall enhancement of neighborhood aesthetics.

Green Infrastructure Projects

Bransten Road Green Street Project: Bransten Road

The Bransten Road Green Street Project incorporated curb extensions and bioretention areas within the street to infiltrate the stormwater runoff collected from the street and sidewalks and minimize the overall impervious area on Bransten Road.

Branston Green Street 


Burton Park Phase II Project: 900 Chestnut Street

This project included a bioretention area that collects and treats stormwater runoff collected from the surrounding impervious surfaces such as the concrete walkways. The bioretention area provides environmental benefits and adds to the park’s overall aesthetics.

Burton Park


Crestview Park: 1000 Crestview Drive

Crestview Park features a large bioretention area that can withstand high volumes of stormwater runoff while improving water quality by removing pollutants.

East Side Connect: Old County Road

The East Side Connect Project included bioswales that collect and treat runoff from surrounding surfaces as well as street trees that enhance stormwater management.

East Side Connect


El Camino Real at Arroyo: Arroyo Avenue and El Camino Real

This project consisted of improvements along the east side of Arroyo Avenue and El Camino Real. The improvements included curb extensions (bulb-outs) and bioretention areas, which provide pollutant removal and water filtration.

El Camino at Arroyo


Honda Dealership: 767 Industrial Road

This project featured a bioretention area that collects and infiltrates stormwater runoff. Stormwater that is directed into the bioretention area is treated by undergoing chemical, physical, and biological treatments.

Honda Dealership Landscape


Industrial Road Landscape: Industrial Road

The Industrial Road Landscape Project incorporated 27 street trees along 300 blocks of Industrial Road. Street trees help control stormwater runoff by capturing and storing water in their leaves and branches for a period before it reaches the ground. Street trees provide other benefits such as improving air quality, reducing urban noise, and enhancing neighborhood aesthetics.

In-N-Out: 445 Industrial Road

This project located at In-N-Out on Industrial Road included a bioretention area next to the drive-through entrance, which serves as an infiltration system that naturally removes pollutants from the stormwater runoff.

Residence Inn by Marriot: 595 Industrial Road

This project at the this hotel included bioretention areas that collect and absorb stormwater treatment. Bioretention areas contain material such as specialized biological soil that slows, retains, and infiltrates stormwater runoff.

Landmark Hotel


Lyngsø: 345 Shoreway Road

The Lyngsø project included a highly-vegetated bioretention area that infiltrates stormwater runoff accumulated from the parking lot.



360 Industrial Rd, San Carlos, CA

This project contained a large bioretention area that can treat high volumes of stormwater runoff that are collected from the parking lot.



Palo Alto Medical Facility: 301 Industrial Road

The Palo Alto Medical Facility features bioretention areas along the walkway in front of the building. The bioretention areas provide stormwater treatment that enhance the facility’s aesthetics.
