There are actually two county programs designed to allow property owners to request monetary credits for stormwater management improvements which have been implemented on their properties.
Stormwater Management Property Tax Credit Program
This is an existing program administered by the Office of Planning and Zoning that provides for a reduction in County Property Taxes for qualified stormwater improvements. For information and applications, click here.
This application must be filled within 45 days after the completion of the qualifying improvements and annually thereafter.
Stormwater Fee Credit Program
This program was developed by the Department of Public Works and, as required by state law, approved by the Maryland Department of Environment (MDE).
This program recognizes the significant stormwater control investments made by certain property ownwers and encourages runoff control practices that proactively and sustainably manage stormwater on private property.
If you are not the current owner of the property, you are not obligated to pay the WPRF.
The WPRF assessments were sent from a list of property owners provided to Anne Arundel County by the Maryland State Department of Assessments and Taxation (SDAT). The error in ownership originates in their records.
Please submit Form 13-5 "Exempt or Incorrect Property Owner" to indicate that you are not the current property owner. In addition, you will need to personally contact SDAT (see below) to request the property information be updated. Once verified, you will not receive bills in the future.
Anne Arundel County
Properties within Residential Zoning Districts are assessed a WPRF based on the median impervious area of all properties within that Tier at a rate of $85 for every 2,940 square feet of impervious area. The rates for each Tier are as follows:
Estimated Impervious Area (sq. ft.)
2nd Year Phase-in (80%) WPRF
Residential properties that fall outside of a Residential Zoning District, for example in Commercial, Industrial or Marine Zoning; are assessed at the same rate as the residential properties in Tiers 1, 2 and 3 ($85 per 2,940 square feet of impervious area). However, the WPRF for these properties is based on the actual calculated impervious area of their individual property.
Property owners may view their zoning districts on the digital map “Anne Arundel County Digital Zoning Layer” prepared by the Office of Planning and Zoning and adopted by the County Council.
For more information regarding the zoning process, visit the Office of Planning and Zoning webpage.
The credit applications are currently under review. Once a decision has been rendered, the Department will instruct the County’s Office of Finance to make any necessary adjustments to the stormwater remediation fee and issue a revised bill and/or refund. Because your credit was submitted before the April 30, 2014 deadline, any fee adjustments resulting from your credit will also apply to the 2014 stormwater remediation fee.
