Regional Stormwater Management Program

The Regional Stormwater Management Program (RSMP) provides funding for the planning, design and construction of regional drainage improvements to reduce the risk of flooding in a specific watershed. To participate, developers may make a payment instead of constructing a detention pond or developers may construct approved off-site drainage improvements.

Rate Structure Modifications

Watershed Protecction is updating the payment structure for the RSMP and the Urban Watershed Structural Control Fund. TThere's more information in the documents below:

RSMP Overview

Developers may only participate in the RSMP if they are able to demonstrate that on-site detention is not needed. They must show that their proposed development will produce no identifiable adverse impact to other nearby properties due to increased runoff.

To use RSMP funds, we use a watershed-wide approach to analyze potential flooding problems, identify appropriate mitigation measures and select site locations and design criteria for regional drainage improvements.

The RSMP is funded through payments into watershed-specific accounts by participants in place of providing on-site detention for a project. Participation payments collected are held in accounts based on watershed boundaries and spent only within the associated watershed. Funds may be used for the following purposes:

Storm drain improvements
Culvert upgrades
Channel modifications
Land and/or easement acquisitions
Property buyouts
Design, permitting and construction of regional pond facilities
Watershed master plans.

Payment and execution of the agreement must occur before the final plat or site plan approval.
