The George W. Kuhn Drain Drainage District operates as a combined sewer system. During dry weather, wastewater flows directly to a Great Lakes Water Resource Recovery facility. When there is heavy rain and stormwater enters the system, excess flow is diverted to the George W. Kuhn retention treatment facility where it is stored, screened and treated. Since most of the district is residential, helping homeowners use green stormwater infrastructure is an effective way to manage stormwater in our changing climate.

RainSmart Rebates offers homeowners up to $2,000 in rebates for installing rain gardens, rain barrels and trees. These projects help capture and slow rainwater or snowmelt. Not only do they help reduce the amount of stormwater entering the combined sewer system, but they also improve water quality, increase tree canopy, support native plants and local pollinators, and aid our community in climate resilience.

Please visit our Resources page. 

Yes. Participants may install up to two rain barrels, two trees and a rain garden. All properties have a maximum rebate amount of $2,000.

Yes. RainSmart Rebates is a reimbursement program. You will pay for your project upfront. After you’ve been accepted into the program, complete a site assessment with program representatives, receive approval, and properly install your project, you can submit your receipts through the RainSmart Rebates Reimbursement Request Form. Your rebate amount will depend on the type of project completed.

If you are unable to pay for supplies or installation, you can apply for the RainSmart Rebates Equity Grant when you fill out your application.

Plan to reserve one hour for your site assessment. During the visit, we will determine what projects will benefit your property and answer any questions you have. After the assessment, you will receive an emailed report explaining which projects you’re eligible for.

No, you don’t have to follow the recommendations, but if you choose to move forward, your project must meet the program requirements.

We recommend you install projects between April and November, depending on the weather and the likelihood of frost and rain. For more guidance, please visit the Resources page.

Any project or portion of a project installed in the right-of-way must first be discussed with your local municipality.

You must install your stormwater project before Oct. 31 of the calendar year you applied. If you are unable to install your stormwater project during your application year, you will need to reapply the following year. 

Yes, you may hire a designer or contractor for your stormwater project. Hiring a professional does not increase the rebate value. Professional costs could exceed rebate limits, and you will need to cover any additional expenses.

You may begin installation after you receive an approval email following the site assessment. Projects installed before receiving approval will not qualify for reimbursement.

Your rain garden plan must include a design and planting list that meets the program’s standards. You are required to submit your rain garden plan to rainsmart@oakgov.com for approval prior to installation.

75% of your plants must be Michigan native species. A small amount of non-native plants are allowed, provided they are not invasive.

Examples of invasive species not allowed include yellow iris, purple loosestrife, garlic mustard, autumn olive, dames rocket, phragmites, Japanese pachysandra, miscanthus (silver grass), periwinkle, heavenly bamboo, Japanese barberry, and burning bush.

Native plant nurseries.

This test measures how quickly water is absorbed by your soil and determines if a rain garden will work well in your chosen location. Use the Soil Infiltration Test Worksheet to record your results.

You can still install a rain garden if your soil doesn’t drain properly, but you will need to improve the soil with sand or organic compost. These changes must be included in your rain garden design plan.

Your rain garden size is calculated by the amount of impervious surface draining to it and the multiplier that is derived from your soil’s drainage rate. You may increase the size of your garden, but you will need approval from the RainSmart Team first. The program will only compensate an additional 20% over the required area.

This must be determined on a case-by-case basis. If you want to build a rain garden to mitigate water coming from your neighbor’s property, please contact rainsmart@oakgov.com.

Depending on how much soil you remove, you may be able to repurpose it on your property or use it as part of a berm around the rain garden. If you need to remove a large amount of clay soil, renting a dumpster or having someone haul it away is an eligible expense for your reimbursement.

This should be discussed during your site assessment. In some cases, a rain garden can help alleviate standing water if additional soil amendments are also made.
