Citywide GSI Project displays the data from
CARTO.GSI_PT_PV. The labels are based on the attribute PROJECT
NAME.
This data will not display when zoomed out beyond 1:3,000.
Seattle Executive Order 2013-01 and City Council Resolution
31459 direct City departments to coordinate to develop an implementation
strategy for managing 700 million gallons of stormwater annually with green
stormwater infrastructure approaches by 2025. These data on the location,
purpose, funder, install year, and best managed practices of GSI installations
in Seattle are gathered and integrated for comprehensive Citywide tracking and
reporting at the project level.
Updated weekly.
