Stormwater Impact Fee – What You Need to Know

Beginning in 2025, all Middletown Township property owners are being assessed a Stormwater Impact Fee to support the cost of providing, maintaining, and repairing stormwater management infrastructure and improving stormwater runoff quality.

This program is designed to protect residents, property, and water quality by ensuring the Township has the funding to manage runoff, reduce flooding, and comply with environmental regulations.

Middletown Township has not previously had a dedicated funding source to support the cost of stormwater management. Due to the age of the community’s infrastructure, existing stormwater management systems are inadequate for modern needs and are in varying stages of disrepair.  Some areas of the Township lack stormwater infrastructure entirely.

In July 2024, the Board of Supervisors established an ad-hoc Stormwater Advisory Committee to assess the Township’s stormwater infrastructure needs, evaluate potential infrastructure improvement projects, and determine the feasibility of a Stormwater Impact Fee.

The Committee identified that the Township needs to invest approximately $1.5 million per year in stormwater infrastructure. Additionally, the committee identified the need to improve maintenance of existing infrastructure and systems in an amount of $200,000 per year. To meet these needs, the Committee recommended a Stormwater Impact Fee to the Board of Supervisors, who acted on this recommendation in December 2024. How Much Will I Pay?

Middletown Township is actively investing in stormwater infrastructure to improve public safety, reduce long-term maintenance costs, and prevent flooding.  More than $9 million of improvements are planned through 2029.  Additional information is available below for improvements planned in 2025.

Langhorne Gables Drainage Improvements

In February 2025, the Board of Supervisors authorized the advertisement of bid specifications for Phase 2 of stormwater improvements in the Langhorne Gables neighborhood.  Construction completion is anticipated by the end of 2025.
These upgrades will improve stormwater flow and reduce neighborhood flooding.

Reetz Avenue Culvert Replacement

Reetz Avenue, a residential street between Hulmeville Borough and I-295, contains a culvert in significant need of repair.
The project includes reinforcing the culvert with a concrete lining and repairing the surrounding embankment.
Once complete, the project will enhance long-term roadway stability and reduce ongoing maintenance costs.  Construction expected to be completed by the end of 2025 Questions & Appeals
