Island County GISThe catch basins data were originally collected in the mid-2000s by road shop crews using a Trimble GPS collector. Data are updated as new catch basins are installed or existing but unmapped catch basins are discovered. Accuracy of GPS ranges from a couple feet to around 15'+. Descriptive information about each catch basin, including type, depth, size and condition, is included in the attributes. The "House_Numb" field is used if the feature is near a known street address. "Location" is used when descriptive information about the feature's location may be useful, as in when the feature is not easily found. "Attention_" is marked "yes" if the feature appears to need some maintenance or repair. "Remarks" is used to add any important information unique to the feature. "Name_of_Sy" is used to identify those features that are part of a named drainage system - most are not.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/43720f23e37b4fd38085b431a69c25a3_0engIsland County Open Data PortalPublicCatch Basins [Washington (State)--Island County]Web servicesWashington (State)--Island CountyWashington (State)Last Modified: 2026-01-08
