Urban Nonpoint Source & Storm Water Management Grant Program

The Urban Nonpoint Source & Storm Water (UNPS&SW) Management Grant Program offers competitive grants to local governments for the control of pollution from diffuse urban sources that is carried by storm water runoff. Grants from the UNPS&SW Program reimburse costs of planning or construction projects controlling urban nonpoint source and storm water runoff pollution.

Who can apply

Eligible applicants

Cities, villages, towns, counties, regional planning commissions, tribal governments and special purpose lake, sewage or sanitary districts may apply. The local government must have either jurisdiction over the project area or be required to control storm water discharge with an inter-governmental agreement between the municipality and the Department of Natural Resources.



For Planning grants, the total state reimbursement amount cannot exceed $85,000. For Construction grants, the total state reimbursement amount cannot exceed $150,000 for construction and engineering, plus an additional $50,000 for land acquisition.

Eligible areas

Eligible areas are urban lands with a population density of at least 1,000 people per square mile or non-permitted commercial or municipally-owned industrial use. Projects may be in areas that are expected to become urban within 20 years.

Planning grant eligible projects

  • Storm water management planning for urban areas;
  • Preparation of local ordinances affecting storm water discharge (construction site or post-construction erosion control, pet waste, or illicit discharge management);
  • Evaluating alternatives for local financing of urban runoff control programs;
  • Administrative costs for the initial establishment of local storm water management funding programs;
  • Illicit discharge detection and elimination program planning;
  • Public information and education activities.

Construction grant eligible projects

Application materials for UNPS Construction projects beginning in 2023 are due April 15, 2022.

UNPS Planning grant applications will not be solicited in 2022. They will be solicited again in 2023.

Department of Natural Resources staff score and rank the applications, and available funds are allocated to the top-scoring applications. Grant award announcements are made in the fall.


The DNR modified the schedule for UNPS Construction and UNPS Planning Grants to request Construction and Planning applications every other year, on alternate years. TRM Small-Scale Urban TMDL applications are currently available annually in January. To apply for a grant, choose the current application and instructions available from the chart below.

Applications must be postmarked and mailed by April 15 of the calendar year prior to the awarded grant start year.

For Urban Stormwater Planning grants, DNR withholds 50% of eligible state cost-share reimbursements until final grant settlement. This withholding amount is automatically calculated and deducted in the Reimbursement Request Form (Form ID 8700-336) based on the grant cost-share rate and total project costs claimed in the reimbursement request.

Grant agreement amendment requests

Successful grant applicants enter into a contractual agreement with the DNR to commit funds for the purpose of implementing grant-eligible best management practices (BMPs).

Grantees wishing to amend their existing grant agreement terms, including project scope, costs, and/or grant period, should contact their DNR Regional Coordinator listed on their grant agreement. Grantees interested in adding, removing, or changing the location of BMPs to be installed, as described in their grant application or current grant agreement, must also complete an Amendment Request Form (Form 8700-308) [PDF].

Cost-share Agreement Forms

Grantees providing grant funds to private landowners must enter into a cost-share agreement (CSA) between the grantee and the landowner, listing the BMPs and establishing the conditions and considerations under which a cost-share recipient agrees to install and maintain the BMPs listed. In accordance with NR 155.22(4), Wis. Adm. Code, the grantee must obtain DNR approval from their DNR Regional Nonpoint Source Coordinator prior to executing the agreement. CSA forms are provided below.

Final report form

A final grant project report must be completed using the appropriate form (linked below) and submitted to the Regional Coordinator for review and approval before final grant reimbursement may be made.
