Description: Feature class StormwaterStructure stores geometry and attributes of a variety of point features delineating inlets, junctions, connectivity, system terminus locations, or other discrete features of interest to aid point-line connectivity or system terminus designations. Only those features within the public right-of-way are included within this data set. Data set does not provide a complete hydrological or infrastructural portrait of the city; only those examined features with significance within the City’s stormwater infrastructure are included. Furthermore, the layer is composed of data collected by multiple different entities working under different or unknown procedural frameworks across an extended temporal scale, resulting in data quality discrepancies across the dataset. Dataset is intended as a system inventory guide, and is not a complete survey-grade assessment of the City’s stormwater system.

Description: Feature class StormwaterPipeIO stores geometry and attributes of constructed pipe end features within the City of Wilmington; the dataset provides information about location and type of inlet/outlet structures associated with closed system stormwater conveyance features. Only those features within the public right-of-way are included within this data set. Data set does not provide a complete hydrological or infrastructural portrait of the city; only those examined features with significance within the City’s stormwater infrastructure are included. Furthermore, the layer is composed of data collected by multiple different entities working under different or unknown procedural frameworks across an extended temporal scale, resulting in data quality discrepancies across the dataset. Dataset is intended as a system inventory guide, and is not a complete survey-grade assessment of the City’s stormwater system.

Description: Feature class StormwaterBMP stores geometry, attributes, and miscellaneous notes describing implemented best management practices across the City of Wilmington. Best management practices refers to "a term used to describe a type of water pollution control. Stormwater BMPs are techniques, measures, or structural controls used to manage the quantity and improve the quality of stormwater runoff" (epa.gov). The layer contains constructed and natural infiltration, wet, and bio-retention type BMPs both publically and privately maintained, permitted and non-permitted. Data set does not provide a complete portrait of the hydrological system or implemented BMPs across the city; only those examined features with significance within the City’s stormwater infrastructure are included. Furthermore, the layer references data collected by multiple different entities working under different or unknown procedural frameworks across an extended temporal scale, resulting in data quality discrepancies within the dataset. Data within this layer was processed using office editing and heads up digitization by City of Wilmington Stormwater Services Staff using unknown procedures and protocols, adding another dimension of uncertainty to the dataset. Dataset is intended to be part of a system inventory guide, and is not a complete survey-grade assessment of the City’s stormwater system or BMP implementation.

Description: Feature class StormwaterChannel stores geometry and attributes of open man-made or natural conveyance features within the City of Wilmington. This dataset includes channels greater than two feet in depth, swales and ditches less than two feet in depth, selected natural streams, selected tidal creeks, and selected pond reaches. Only those features within the public right-of-way are included within this data set. Data set does not provide a complete hydrological or infrastructural portrait of the city; only those examined features with significance within the City’s stormwater infrastructure are included. Furthermore, the layer is composed of data collected by multiple different entities working under different or unknown procedural frameworks across an extended temporal scale, resulting in data quality discrepancies across the dataset. Dataset is intended as a system inventory guide, and is not a complete survey-grade assessment of the City’s stormwater system.
