Credits

parking lot retrofit.JPGProperty owners who have on-site or off-site Best Management Practices that reduce the quantity or improve the quality of stormwater discharged from their property may be eligible for a Clean Water Act Fee reduction credit. In addition, property owners who can demonstrate substantial Financial Hardship as a result of the fee may also qualify for a fee reduction credit

Clean Water Act Fee reduction credits shall be determined in accordance with the following:

  • The fee reduction credit only applies to a reduction of the Impervious Area Fee.
    The Administrative Fee ($20.58) will continue to be collected in its entirety for each tax account.
  • The Director of the Department of Environmental Resources or his designee shall make the final determination on the amount of fee reduction credit to award for on-site or off-site stormwater management.
  • A property that does not contain a Best Management Practice may be credited if located within the same drainage area as another property that contains a Best Management Practice if both properties have the same owner.
  • All Best Management Practices for which credits are being requested are subject to an inspection and field verification by the Department of Environmental Resources. Access to the Best Management Practices must be granted to the Department in order for credit to be awarded.
  • In order to receive a fee reduction credit, all Best Management Practices must be functioning correctly, must be maintained in good condition, and must pass a Department of Environmental Resources inspection.
  • Once approved, credits are valid for three years. To renew the credit, the property owner must reapply to the Department of Environmental Resources.

Amount of Fee Reduction Credit

The amount of fee reduction credit and the method of determining the credit varies depending on the property type. Some examples are given below for different property types.

Single Family Residential or Multi-Family Properties

 

Amount of Fee Reduction Credit: up to 100% reduction of the Impervious Area Fee

How to Qualify: To qualify for a fee reduction credit, property owners must have installed Best Management Practices on their property using the County’s latest stormwater management ordinance standards for Environmental Site Design, and Best Management Practices must be maintained in good condition.

How Credits are Determined: Fee reduction credits will be determined based on the Best Management Practice’s ability to treat three different types of untreated impervious area: roof, driveway/parking lot, and all “other” (sidewalks, sheds, patios, pool decks, etc.), as follows:

  • Treating the roof will qualify for up to a 40% fee reduction credit (partial credits available*)
  • Treating the driveway/parking lot will qualify for up to a 50% fee reduction credit (partial credits available*), and
  • Treating all “other” (sidewalks, sheds, patios, pool decks, etc.) impervious areas will qualify for up to a 10% fee reduction credit (partial credits available*)
  • *Partial credits are available on a 1:1 basis, for example treating 1/2 the roof will qualify for a 20% fee reduction credit, or treating half the driveway/parking lot will qualify for a 25% fee reduction credit, as determined by a field inspection.
  • Note that certain residential property owners may also be eligible to receive a rebate to cover the cost of BMP materials. For more information, please see the Rain Check Rebate Program website.

Example:

My property has four rain barrels at each downspout that treat the roof runoff, and the driveway is made of permeable pavement.

My property is zoned R55, medium size lot, Tier Two. Based on this zoning, my Clean Water Act Fees are:

Administrative Fee = $20.58
Impervious Area Fee = $20.90
Total Clean Water Act Fee = $20.58 + $20.90 = $41.48

I apply for a fee reduction credit for the rain barrels and permeable pavement on my property. The County reviews and approves the request and determines that you are eligible for a 90% fee reduction credit (40% for treating the roof + 50% for treating the driveway, from above). The credits are applied as follows:

Administrative Fee = $20.58
Adjusted Impervious Area Fee = $20.90 –90% = $2.09
Adjusted Total Clean Water Act Fee = $20.58 + $2.09 = $22.67

Condominiums

 

Amount of Fee Reduction Credit: up to 100% reduction of the Impervious Area Fee.

How to Qualify: To qualify for a fee reduction credit, property owners must have installed Best Management Practices on their property using the County’s latest stormwater management ordinance standards for Environmental Site Design, and Best Management Practices must be maintained in good condition.

How Credits are Determined: Fee reduction credits will be determined based on the Best Management Practice’s ability to treat three different types of untreated impervious area: roof, parking lot, and all “other” (sidewalks, sheds, patios, pool decks, etc.), as follows:

  • Treating the roof will qualify for up to a 40% fee reduction credit (partial credits available*),
  • Treating the parking lot will qualify for up to a 50% fee reduction credit (partial credits available*),
  • Treating all “other” (sidewalks, sheds, patios, pool decks, etc.) impervious areas will qualify for up to a10% fee reduction credit (partial credits available*)
 

*Partial credits are available on a 1:1 basis, for example treating 1/2 the roof will qualify for a 20% fee reduction credit, or treating half the driveway/parking lot will qualify for a 25% fee reduction credit, as determined by a field inspection.

Note that certain condominium property owners may also be eligible to receive a rebate to cover the cost of BMP materials. For more information, please see the Rain Check Rebate Program website. 

The fee reduction credit will be distributed equally among all the individual condominium units.

Example:

I am a condominium Homeowner’s Association representing 50 individual building units/tax accounts. I have two rain gardens on my property that treat the sidewalks and a parking lot. The County has determined that the total amount of impervious area on the combined parcels is 100 Equivalent Service Units (1 Equivalent Service Unit= 2,465 square feet) which includes the common areas (sidewalks and parking lot) and all of the building rooftops. My Clean Water Act Fees are: 

Administrative Fee = $20.58 per account
Impervious Area Fee = 100 Equivalent Service Units x $20.90 = $2090.00 for all accounts
Impervious Area Fee per Building Unit = $2090.00 / 50 building units= $41.80 per account
Total Clean Water Act Fee = $20.58 + $41.80 = $62.38 per account

I apply for a fee reduction credit for the rain gardens on my property. The County reviews and approves the request and determines that you are eligible for a 60% fee reduction credit (50% for treating the parking lot + 10% for treating the sidewalks, from above). The credits are applied equally to each parcel as follows: 

Administrative Fee = $20.58 per account
Adjusted Impervious Area Fee = $2090.00 – 60% = $836.00 for all accounts
Adjusted Impervious Area Fee per Building Unit= $836.00 / 50 building units = $16.72 per account
Adjusted Total Clean Water Act Fee = $20.58 +$16.72= $37.30 per account

Non-Residential Properties (Industrial, Commercial, and Institutional Properties)

Amount of Fee Reduction Credit: up to 100% reduction of the Impervious Area Fee.

How to Qualify: To qualify for a fee reduction credit, property owner must have installed one or more structural or non-structural Best Management Practice(s) or Environmental Site Design practices on their property. Structural Best Management Practices must have been approved and certified by the County.

How Credits are Determined: Fee reduction credits for non-residential properties are awarded as follows:

  • Roof treatment – Up to a 25% fee reduction credit (partial credits available*)
  • Parking lot treatment – Up to 45% fee reduction credit (partial credits available*)
  • Green lawn care** – 5% fee reduction credit
  • Older legacy pond – 15 to 25% fee reduction credit depending on year of installation:
    Before 2002 – 15% fee reduction credit
    2002 to 2008 – 20% fee reduction credit
    After 2008 – 25% fee reduction credit
  • Other – County to make determination.

*Partial credits are available on a 1:1 basis, for example treating 1/2 the roof would qualify for a 12.5% fee reduction credit, or treating 1/2 the parking lot would qualify for a 22.5% fee reduction credit, as determined by a field inspection. 

**Note that green lawn care practices must be implemented by a business that is listed in the Maryland Department of Agriculture’s Searchable Pesticide Database under the appropriate license category.

Note that certain non-residential properties, such as commercial businesses, may also be eligible to receive a rebate to cover the cost of BMP materials. For more information, please see the Rain Check Rebate Program website.

Example:

I am a commercial business and have a legacy pond on my property that was built in 2005. The County has determined that I have 25 Equivalent Service Units (1 Equivalent Service Unit = 2,465 square feet) of impervious area on my parcel which includes a large parking lot and my building rooftop. My Clean Water Act Fees are: 

Administrative Fee = $20.58
Impervious Area Fee = 25 Equivalent Service Units x $20.90 = $522.50
Total Clean Water Act Fee = $20.58 + $522.50 = $543.08

I apply for a fee reduction credit for the legacy pond on my property. The County reviews and approves the request and determines that you are eligible for a 20% fee reduction credit (from above). The credits are applied as follows: 

Administrative Fee = $20.58
Adjusted Impervious Area Fee = $522.50 – 20% = $418.00
Adjusted Total Clean Water Act Fee = $20.58 + $418.00 = $438.58
