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

            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 and submitted to the Regional Coordinator for review and approval before final grant reimbursement may be made.

            Urban Nonpoint Source Construction and Urban TRM grant final reports must be submitted using the BMP Implementation Tracking System (BITS) as of December 5, 2022. Grantees may no longer use the Final Report Form (3400-189U).

            • The BITS web page includes a user guide and video tutorial to aid grantees submitting their final report via BITS for the first time. DNR staff are available to answer questions and assist grantees with using BITS.

            Urban Nonpoint Source Planning grants must submit final reports using the form linked below:
