A Green Infrastructure Vision for Priority Development Areas in the Grayson Creek Watershed

Contra Costa County, California

This project identified policies and design strategies that would mitigate flood risk and reduce water pollution in regions designated for dense transit-oriented development.  We merged green infrastructure BMPs with municipal complete streets policies to propose “sustainable streets”, which make use of vegetated strips doubling as green infrastructure to shield pedestrians and bicyclists from vehicular traffic. We developed a GIS method for determining the suitability of various GI types to individual streets based on street slope, street width, soil type, adjacent land use, and location within the watershed.

 

Since the region’s gray stormwater infrastructure is reaching the end of its useful life, we recommended that flood control channels be naturalized and re-envisioned as focal points of waterfront development, increasing property values and attracting people to local businesses. Several lots planned for large housing developments are within the FEMA 100-year floodplain, so our project team proposed redesigns for the developments with parks that double as retention ponds.

 

This project was a collaboration with two other students in UC Berkeley’s graduate environmental planning studio. I participated in all phases of research design and model development, and produced many of the final graphics.
