Drainage Utility Fee
WHAT IS A DRAINAGE UTILITY FEE?
A Drainage Utility Fee (DUF) is a monthly charge assessed to all properties based on impervious cover. Revenue from the fee is used to improve and maintain the City's drainage infrastructure system and to protect water quality.
WHAT IS IMPERVIOUS COVER?
Impervious cover includes surfaces that do not allow rainfall to absorb into the soil creating runoff into waterways. Examples of impervious cover include rooftops, driveways, walkways, patios, sheds, parking lots and loading docks.
WHEN DOES THE NEW DRAINAGE UTILITY FEE STRUCTURE BEGIN?
Drainage Utility Fees have been in place since 2001; however, City Council adopted a change to the calculation of the DUF in July 2019. Beginning February 1, 2020, the DUF will be calculated using the impervious cover based method.
HOW MUCH IS MY FEE?
The DUF for single-family properties and duplex properties remains $6 per month.
The DUF for non-residential properties is based on an Equivalent Residential Unit (ERU). Non-residential customers are defined as commercial properties and those multi-family properties with three or more units. An ERU is a unit of measurement of impervious cover based on the average residential property. The City of Killeen current adopted value is ERU = 3,027 square feet of impervious cover. The value of impervious cover on each lot was measured based on 2015 aerial photography and construction plans. You can view the amount of impervious cover for your parcel using the Drainage Fee Map.
HOW DO I REDUCE MY FEE?
There are two ways for non-residential customers to reduce their monthly DUF. The first is to remove any excessive impervious cover from the parcel and revegetate the disturbed area. Non-residential customers may apply for and the City may grant stormwater credit(s) for voluntary use of stormwater best management practices (BMPs). The total amount of stormwater credit shall not exceed 40%. The list of approved BMPs for this credit include:
- Community Cleanup Program 5%
- Parking Lot Sweeping Program 5%
- Rainwater Harvesting 10%
- Riparian Preservation 10%
- Bioretention/Rain Garden 10%
- Multi-Stage Detention 20%
- Retention Ponds 40%
- Green Roofs 40%
Non-Residential customers may fill out and submit the request for stormwater credits utilizing the DUF Adjustment Fee form in the Helpful Links section below. The City is in the process of developing the credit standards and will have them released on this page prior to the new fee going into effect.

Drainage Utility Fee Meetings Scheduled
The monthly Drainage Utility Fee (DUF) for most non-residential properties, including commercial and multi-family with three or more units, will be affected by a new rate calculation that takes effect February 1, 2020. The fee for single-family residential and duplex properties will remain $6 per month.
Two public meetings are scheduled to help non-residential customers understand the fee change. Staff will make presentations and be available to answer specific property questions at the following times:
October 15 5 p.m. Transportation Building, 3201 S. WS Young Drive
November 19 1 p.m. Utility Collections, 210 W. Avenue C
The DUF is a monthly charge assessed to all properties that has been in place since 2001. Revenue is used to improve and maintain the City’s drainage infrastructure system and to protect water quality. Programs work to reduce flooding, erosion and pollution to protect lives, property and the environment.
In July, City Council adopted a change to the DUF calculation for non-residential properties that is based on actual impervious cover. Impervious cover includes surfaces that do not allow rainfall to absorb into soil thus creating runoff into waterways. The calculation uses an Equivalent Residential Unit (ERU), which is a unit of measure of impervious cover based on the average residential property. One ERU equals 3,027 square feet of impervious cover. That value is then applied to each non-residential property based on actual impervious cover as identified in 2015 aerial photography and construction plans.
Non-residential customers may reduce their monthly rates by removing any excessive impervious cover and revegetating the disturbed area or by applying for stormwater credits for instituting best management practices.
The City has created an online map that shows each property and its current and proposed fees. Non-residential customers are encouraged to visit the map to see the proposed fees and to identify any changes to their properties that may have occurred since 2015.
A dedicated Drainage Utility Fee webpage, KilleenTexas.gov/DUF, contains basic fee information and links to the full ordinance, the property map, best management practices and other resources.
