Charrette participants place ideas on SF map
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.
Recent Past Events
We want your input on neighborhood sewer system challenges and feedback on proposed improvement solutions! There will be many opportunities for public input through the adoption of the Urban Watershed Plan in 2015.
|Planning Game Workshop – November
Thank you to everyone who attended our interactive workshop on Saturday, November 16, 2013 to help plan necessary upgrades to San Francisco’s combined sewer system. The workshop was a great success for the Urban Watershed Assessment and featured the interactive watershed planning game to generate ideas for green and grey infrastructure solutions for San Francisco’s Islais Creek, Sunnydale, and Yosemite watersheds. Thank you again! Your input will contribute to the SFPUC’s Urban Watershed Assessment and the next 20 years of sewer system upgrades through the Sewer System Improvement Program.
