WPRF Credit Program

Eligible property owners in Anne Arundel County have the opportunity to reduce their Watershed Protection and Restoration Fee (WPRF) assessments by up to 50% for proactive and sustainable uses of stormwater runoff controls. The WPRF Credit Program Policy and Guidance document for Anne Arundel County provides the Department of Public Works the framework and procedures needed to administer the program.

In addition, the WPRP established the WPRF Stormwater Remediation Fee Credit Agreement to provide credit to single-family property owners that have installed small-scale (e.g., under 5,000 Sq.ft land disturbance) stormwater BMP’s on their property.  For questions about the WPRF Credit Program contact us at 410-222-0530. 

The Program's Goals
  • Recognize the significant stormwater control investments already made by certain property owners.
  • Encourage practices that proactively and sustainably manage runoff on private property.
  • Support Watershed Protection and Restoration Program goal to minimize the impact of land development on water resources.

  • Maximum Credits
    WPRF credits are applicable for three years provided the associated runoff controls are operated and maintained in accordance with the most recent credit application.
  • Partial Credit
    • Partial credit is available for portions of the total impervious surface treated with one or more of the eligible runoff control practices or activities under the stormwater policy.
    • Owners must demonstrate and compute the amount of the impervious surface treated using eligible runoff practices compared to the property's overall impervious surface area. 
    • Fractional amount of treated to overal impervious surface of a property is multiplied by 50% (maximum allowable credit).
    • Credit Calculation:
      • (Treated Impervious ÷ Total Impervious) x Program's Maximum Allowable Credit = Fee Reduction %.
    • Examples:

    Non-Residential and Multi-Family 

    ExampleTotal Impervious  (Acres)Treated Impervious  (Acres)Credit CalculationCredit Reduction

  • Renewal of Credit

    Approved credits are valid for three years.  After three years, to continue to receive credit, functional verification of the BMP(s) is required by the end of the second year.  Practices must be functioning as designed, operated, and maintained in accordance with the most recent credit application.  

    Only NPDES Permit holders are required to complete a renewal application.

    All initial applications and any re-submittals must be mailed to:

    Anne Arundel County DPW

  • Inspection of BMPs Associated with Approved Credit
    It is an owner's responsibility to inspect and repair their practices to ensure that they are functioning as designed and detailed in the approved credit application. In addition, the County reserves the right to inspect, at any time, stormwater management practices applied toward receiving a credit. Those inspections will be in accordance with an executed Inspection and Maintenance Agreement for Private Stormwater Management or WPRF Credit Agreement.
     
    Complete inspection information is available in the Stormwater Fee Credit Program Policy and Guidance document for Anne Arundel County.  
  • Enforcement
    Inspections and documentation are the primary methods employed to monitor approved credits.
     
    Failure to maintain and operate the stormwater management practice in strict compliance with County Approved Plans, Maintenance Agreements, WPRF Credit Agreement, County Standards, Stormwater Management Practices and Procedures Manual, and/or the 2000 Maryland Stormwater Design Manual, Volumes I and II, and Supplements will result in the loss of the credit.
