Eligible Rebate Projects

The projects listed above are the only types of stormwater retrofits that are eligible for rebates under the Rain Check Rebate Program. Applicants will not be eligible for a rebate if the project is part of the permit approval requirements for new building construction or renovations, or if the property is located within a municipality that has a similar rebate program for stormwater management projects.

An applicant is eligible for a rebate as long as: 1) the project is established on property located in Prince George’s County; 2) the application for the project was approved within 12 months of the completion date; 3) DER inspected the completed project and found it to be in compliance with its original approved application; and 4) the project follows DER's best practice guidelines and criteria for that type of project. If the property is part of a Homeowners’ Association (HOA), the applicant must provide a letter or other documentation showing HOA approval of the project.

DER must pre-approve all applications prior to implementation, with the exception of a rain barrel project. However, the rain barrel project must meet eligibility criteria established by DER to receive a rebate and DER must receive all receipts or invoices within 12 months of application approval. All invoices and receipts for the entire amount of the requested rebate must be submitted to DER for review and approval. Rebates will be awarded on a first-come, first-served basis.

The amount of a rebate cannot exceed the cost of the project. The maximum rebate is $2,000 for residential projects and $20,000 for commercial, multi-family dwelling, nonprofit entities, or not-for-profit organizations, including housing cooperatives. An applicant may complete multiple projects until the rebate ceiling is met. Nonprofit organizations established pursuant to Section 501(c)(3) of the Internal Revenue Code may annually perform eligible stormwater management projects on public property that benefit the community up to the $20,000 ceiling.

To receive a rebate, the applicant will be required to sign an agreement with the County that will allow for the placement of promotional signage for the Rain Check Rebate Program on their property, photograph the property for possible publication, and do follow-up evaluations. There will also be a voluntary option to agree to participate in any project tours the County holds to promote the Rain Check Rebate Program. Applicants for a commercial or public project will be required to sign an operations and maintenance agreement for the project.
