The San Francisco Public Utilities Commission (SFPUC) is undertaking the multi-billion-dollar Sewer System Improvement Program (SSIP) to modernize the city’s infrastructure and ensure the system functions in the event of a major earthquake. These improvements require construction in every neighborhood of the city as well as significant rate increases for residents. A substantial amount of public input is required before and during the project, however it has proven historically difficult to get the public to attend in-person forums and workshops.

SFPUC-logo-vertUsing an iPad-based questionnaire, Civinomics conducted a massive point-in-time survey of city residents. The survey provided respondents with an overview of the SSIP and gauged their support for its different elements. Respondents were asked to rate the different types of green infrastructure options, indicate on a map interface where in their community they would like a project to go in, and select which types of general neighborhood improvements they would like to see more of in their community (bicycle-friendly infrastructure, pedestrian safety enhancements, increased open space, etc).

Civinomics interviewed a statistically representative sample of 400 residents in each of San Francisco’s eight watersheds. This included the 35% of the city’s population that speaks Spanish, Mandarin and Cantonese, as well as traditionally under-served neighborhoods like Sunnydale and Bayview-Hunters Point. As a result, the SFPUC was able to identify the highest need areas and prioritize project implementation in every neighborhood.
