RSMP Participation Handbook 

Use this document as a comprehensive reference for Regional Stormwater Management Program participation application and approval. Find drainage analysis guidance, modeling requirements, and more information about the program.

RSMP Feasibility Viewer 

Use this tool to determine whether a project is potentially feasible for Regional Stormwater Management Program participation. The viewer will either determine that a project is potentially feasible for participation and lead the user to schedule feasibility meeting with the Regional Stormwater Management Program team or that a project is not feasible. If the project is not feasible for Regional Stormwater Management Program participation, the applicant should work with their assigned drainage reviewer to provide onsite detention per code and criteria. 

The RSMP Feasibility Determination is the first step in the RSMP Application process.
