Urban Watershed Planning Charrettes (2007-2009)

As part of its efforts to explore locations for green infrastructure in San Francisco, our Urban Watershed Management Group hosted three Urban Watershed Planning Charrettes between 2007 and 2009 to engage the larger community in creating a vision for what stormwater management could look like in San Francisco's future. 

A charrette is an intensive brainstorming activity in which a group of people collaborates to complete a design project in a finite amount of time. Over 100 participants attended the charrettes, representing public agencies, engineering and design companies, nonprofit organizations, community groups, stormwater experts, and unaffiliated San Francisco citizens.

Participants divided into groups by watershed basin, and over the course of the day, each group developed a set of green stormwater management recommendations for its particular basin through the format of a game. Capital costs as well as peak flow and volume reductions were estimated for each LID measure. The object of the game was to meet specified stormwater reduction targets within a finite budget. Each group prioritized their recommendations and presented them to the entire charrette audience at the end of the evenings. The SFPUC will use these creative ideas to further identify, analyze and prioritize future stormwater management efforts in San Francisco.

SSIP Planning Game Workshops (2013-Present)

UWA Planning Game Workshops
As part of SSIP, the Urban Watershed Assessment (UWA) planning process includes interactive watershed planning game workshops to generate ideas for green and grey infrastructure solutions for the next 20 years of sewer system upgrades through the Sewer System Improvement Program the City’s eight watersheds. Ideas generated during the workshop will be considered by the SFPUC and evaluated for technical feasibility and cost effectiveness.
