- Note: Altered forms will not be accepted. If you believe an item does not apply, write "NA" or "not applicable" rather than deleting it. Extending the length of a form in order to add more information is acceptable.
Updated versions of the models as listed in the Stormwater management Rules, dated 23 December, 2006, are acceptable as long as the core methodology has not been changed. The use of models using major differences to the conceptual intent or any other approach at modeling stormwater detention and management would need to be approved by the DEP.
A popular model is the HydroCAD Model used for modeling stormwater runoff.
HydroCAD provides a wide range of commonly used drainage calculations including:
SCS, NRCS, SBUH runoff hydrographs
- Rational Method with automatic IDF curves
- Hydrograph routing though ponds and reaches
- Automatic hydraulics and culvert calculations
- Automatic detention storage calculations
- Easy management of multiple rainfall events
- Easy-to-use graphical format usable on any PCs
- Lake Stormwater Phosphorus Compensation Fee Program
