Seattle Green Stormwater Infrastructure

This layer displays Citywide Green Stormwater Infrastructure Best Management Practices (City-wide GSI BMP) and Citywide Green Stormwater Infrastructure projects (City-wide GSI Project). Citywide GSI BMP is sourced from CARTO.GSI_BMP_PT_PV. Labels are based on the attribute BMP. BMP codes listed in the BEST MANAGED PRACTICE (GB_BMP_TEXT) field are defined as follows: Code Value Text Value BIO Bioretention, infiltrating, installed by others BIN Bioretention, infiltrating, installed by SPU BND Bioretention, non-infiltrating, with detention BSU Biofiltration swale with underdrain BSW Biofiltration swale without underdrain BUC Bioretention swale, non-infiltrating, with underdrain in CSO basin BUN Bioretention Swale, non-infiltrating, with underdrain in non-CSO basin CRG Cistern to rain garden CSS Cistern on single family property CST Cisterns DCD Trees, deciduous, newly planted or retained EVR Trees, evergreen, newly planted or retained GRE Green roof—evapotranspiration component GRF Green roof—engineered soil media PPS Permeable paving surface PPF Permeable pavement facility REM Impervious surface removed RGN Rain garden RWH Rainwater harvesting Purpose field attributes: Code Value Text Value ART Agency-led Retrofit CRT Community-led Retrofit FC Stormwater Code Flow Control FCO Stormwater Code Flow Control and On site Stormwater Management FWO Stormwater Code Flow Control and Water Quality Control and On site Stormwater Management FWQ Stormwater Code Flow Control and Water Quality MEF Stormwater code Maximum extent Feasible - use through Dec 2014 OSR Stormwater code On site Stormwater Management requirements - use Jan 2015 forward OTH Other RW Rainwise SGF Seattle Green Factor VL Voluntary WQO Stormwater Code Water Quality Control and On site Stormwater Management WQO Stormwater Code Water Quality Control Funder Field: Code Value Text Value CO Community organization CON Contractor DPR Parks and Recreation DPS Parks and Recreation/SPU KC King County OTH Other POS Port of Seattle PPP Public / Private Partnership PRV Private SCL Seattle City Light SDT Seattle Department of Transportation SPU Seattle Public Utilities STA State of Washington SWC Stormwater Code UNK Unknown UW University of Washington 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.

全市绿色雨水基础设施项目图层的数据来源于CARTO.GSI_PT_PV，其标签基于PROJECT NAME（项目名称）属性字段生成。当缩放比例小于1:3000时，该图层将不会显示。
根据《西雅图行政命令2013-01》与市议会决议31459，西雅图各市政部门需协同制定实施策略，计划至2025年通过绿色雨水基础设施手段，每年管理7亿加仑雨水径流。
本数据集整合了西雅图市绿色雨水基础设施的位置、用途、资助方、安装年份及最佳管理实践等信息，用于全市范围的项目级综合追踪与报告，更新频率为每周一次。
