Springfield Township Data

Stormwater Basin Data-Springfield Township

Summary

All stormwater basins draining to tributaries of Wissahickon Creek in Springfield Township were mapped by PWD in 2006. PWD scientists, contractors, and co-op students from Drexel University examined topographic maps to identify depressions (concentric rings) that were likely to be stormwater basins. Once this screening procedure was complete, the potential basin locations were visited for field verification and photographed with a digital camera. A GPS-enabled ruggedized tablet PC was used to capture points at each basin and record descriptional attributes to GIS. The following basic information was collected about each basin:

Data Field	Data Type	Description
Name	text	Basin address or development name
Area	numeric	Basin area in square feet
Inlets/Outlets	numeric	Number of inlets/outlets
Low Flow Channel(s)	Yes/No	Whether low flow channels are present
Permanent pool(s)	Yes/No	Whether permanent pools are present
Forebay(s)	Yes/No	Whether sediment forebay is present
Outlet Condition	text	Describes condition of outlet structure
Vegetation	text	Description of vegetation type

NOTE: These are the basic attributes only; visit the GIS Metadata Page for more information.
