Some initial questions that came up are as follows:
1. When did these processes/applications get implemented?
The stormwater utility credit processes/applications were implemented in 2010.
2. How many rain barrel and rain garden applications are filled out each year for the last
couple years?
Please see the table below for 2023–2025 totals. We also included riparian credit
applications because that is another available credit for eligible property owners
adjacent to certain water bodies. Please see the attached riparian map for your reference.

3. Have you received feedback from applicants about the form or process? Is so, what has
the feedback been?
We have received minimal direct feedback on the forms or process, but property owners
occasionally call with questions about how to determine impervious versus pervious
surface areas, and staff is able to help provide those numbers and any clarification they
need.
4. How does the credit work? How is the financial incentive applied?
After an application is submitted, staff review it, conduct a field visit, and complete
calculations to determine the reduction amount based on the impervious area draining
to the rain barrel, rain garden, or to an eligible riparian waterbody as described in the
application. Once approved, the credit is applied as a deduction on the property’s
monthly stormwater utility bill.
5. Other municipalities storm water utility credit forms:
For comparison, attached are examples of the storm water credit policies from the City
of Appleton, City of Green Bay, City of Madison, and the City of La Crosse.
6. Financial aspects and how the credit is applied:
The $10 application fee is a one-time fee paid when the application is submitted, and
while the up-front cost may initially appear higher than the credit value, on average, the
fee is typically recovered within a few months and savings continue thereafter.
