General questions
EMCs and runoff coefficients
Land use
- How do I determine what land use to use?
- See this section for definitions of land uses.
- Why is there only one residential land use option?
- Users can create additional land uses, including different types of residential land use, such as low density residential. In the land use column of section 1, enter the desired land use and associated emc and runoff coefficient.
Drainage areas and subwatersheds
Documentation and submittals
- What will MPCA look for in submittals?
- This page provides some information about what MPCA's review might consider.
- What level of sub watershed is the MPCA expecting? The the area in the permittee identified in the TMDL/WLA, or a more detailed HUC subwatershed?
- This is a decision the user needs to make. Use a drainage system that makes sense from a modeling standpoint. It may be that multiple Excel files would be needed for larger and more complex drainage systems.
