Outfalls are defined and inventoried according to EPA's Storm Water Phase II Final Rule (USEPA, 1999). This data set includes structures owned by the City as well as privately-owned outfalls and outfalls owned by the State of Vermont. The emphasis in developing this data set has been on city-owned outfalls; the inventory of state and privately-owned outfalls is not as complete or accurate as city-owned outfalls. This inventory has been compiled using a variety of source data sets and data collection techniques. Initial data sets used for the develoment of this layer were provided by the Chittenden County Regional Planning Commission and the Vermont Agency of Natural Resources. Data have been revised and added using site plans, as-built drawings, orthophotograph interpretation, GPS, and field inspections by South Burlington stormwater utility staff. A separate End of Pipe layer has been developed to map locations where stormlines and conveyances end but are not technically outfalls. This data set was developed to aid in stormwater management in the City of South Burlington.

ArcGIS 9.X Metadata imported. withheld 20100112 10554800 This data set has not been checked for topological integrity. This dataset reflects the current inventory of stormwater outfalls within the City of South Burlington boundary. While this data set includes state-owned and privately-owned outfalls, the emphasis on data collection has been on outfalls owned by the City of South Burlington. As a result the inventory of state and private outfalls is not as complete and accuracte as city outfalls. The City's inventory of stormwater infrastructure is ongoing and is not yet complete. Errors and omissions may exist. Varies, depending on method of data collection. Generally unknown.
