Stormwater Impact Fee

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?

Single-Family Residential Properties:

• Flat fee of $5 per month ($60 per year) for each developed residential parcel. This applies to freestanding (single-family) homes, townhomes, duplexes, and condominiums.

Non-Single Family Residential Properties
(e.g., commercial, industrial, and multifamily parcels):

• Tiered fee based on impervious surface area (determined using GIS data)
• Fees assessed from a minimum of $12 per month ($144 per year) to a maximum of $500 per month ($6,000 per year) per parcel.

Tier	Impervious Area (IA) Range (sq. ft.)	Annual Fee
Tier 0	< 400 sq. ft.	None
Tier 1	400 – 4,000 sq. ft.	$144.00
Tier 2	4,001 – 6,000 sq. ft.	$216.00

Tier 4	> 8,000 sq. ft.	$144.00 per 4,000 sq. ft. IA**

**Non-Single Family Residential Property maximum fee of $6,000 per year.
The total projected annual revenue from the Stormwater Impact Fee is approximately $1.79 million. These funds will be used solely for stormwater-related expenses.

Stormwater Improvement Projects



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

Construction of a $1.6 million stormwater infrastructure project in the Langhorne Gables began in September 2025.  The project includes installation of more than 3,300 feet of new underground stormwater pipes.  Completion is anticipated by early 2026.
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 begin in early 2026. Credit Policy
 

A Stormwater Impact Fee Credit Policy Manual was adopted by the Middletown Township Board of Supervisors on November 17,2025.  This policy outlines credit opportunities that are available for Residential and Non-Residential property owners.  As part of this policy, Residential property owners can receive a credit for participation in community service programs. 

The current dates for Stormater Impact Fee Credit Programs are:

• Clean Up Day (specific locations to be determined)
  • June 6, 2026
  • October 10, 2026
• Tree Plantings (specific locations to be determined)
  • October 17, 2026
• Rain Barrel Workshop
  • TBD

The stormwater credit program provides an opportunity for nonresidential and residential property owners to reduce their stormwater impact fee. The credits are available if the property owner performs specific actions that reduce the impact of stormwater generated from their property. This policy does not change stormwater management requirements for new development or redevelopment or relieve a property owner or developer from complying with those requirements.
 
Single-Family Residential Property Credits
Participation in an approved Township community service activity is the only method to earn credit for a single-family residential property.  The list of approved activities will be updated on the Township’s website each year and pre-registration through the Township’s Park & Rec website is required.  No application fee shall be charged. 
Participation in the credit program is available to the property owner(s) themselves, any legal tenant of the property, or any of the property owner’s minor children.

• Community Service Credit – Annual Enrollment
  • Participation in approved community service activities
    • 1 activity = 10% credit
    • 2 activities = 15% credit
  • Maximum annual credit is 15% per Single-Family Residence
  • The credit will be applied directly to the Stormwater Impact Fee bill
    • Activity Date January 1 – April 1:  Credit applied to current year bill
