Item 4. Stormwater Charge Credits, Grants, and Appeals Manual 1.0 General Information 1.1 Overview The City of Dover’s (the City) stormwater management program aims to manage both the quantity and quality of stormwater runoff within the City and its local surface waters, recognizing them as important resources. The major goals of this program are: • Reduce the amount of pollutants discharged into the surface waters including rivers and creeks; • Manage the rate and volume of stormwater discharged to the City’s system as well as local surface waterbodies; and • Comply with the regulatory requirements of the City’s National Pollutant Discharge Elimination System (NPDES) Phase II permit. To mitigate the impact of pollutant loads on rivers, the City is engaged in several stormwater activities, including pre‐ and post‐construction stormwater management, watershed planning and protection, and surface water quality enhancement efforts. These efforts protect City streets and properties from flooding, erosion, water pollution, property damage, and also enable the City to comply with federal and state regulatory requirements. 1.2 Stormwater Charge With formal adoption of a Stormwater Utility, the City also implemented a stormwater charge, effective July 1st, 2024, pursuant to City Code Chapter 110, ARTICLE V. The stormwater charge was created to provide a designated source of revenue to fund the City’s stormwater management Operations & Maintenance (O&M) costs and capital stormwater system infrastructure costs. A key objective of the stormwater charge is to facilitate equitable recovery of the City’s stormwater management costs from all the parcels within the City’s limits. Typically, it is not feasible to directly measure the actual stormwater runoff and its associated pollutant loads that a parcel contributes to the system. Hence, a stormwater charge is established based on a surrogate measure such as a parcel’s estimated effective impervious area. Impervious area typically refers to any hard and compacted surface area including paved areas, hard undeveloped surfaces, buildings, rooftops, driveways, walkways, decks and patios, compacted grassed areas and parking lots. The approach that is used to estimate the effective impervious area for the residential and all other stormwater classes of properties is described in the following sections. a) Residential Parcels For all the residential parcels (Single-family Residential Stormwater Class), the impervious area is calculated based upon a three-tiered system. 31

Item 4. Stormwater Charge Credits, Grants, and Appeals Manual The impervious area was determined based on impervious coverage files from the Office of State Planning Coordination. Single-family uses were delineated and the impervious cover in each zoning district was divided by the number of lots to derive the average single-family impervious cover of each zone. From this point, residential zoning districts were grouped into tiers that have reasonably similar impervious covers as listed in Table 1, in the Appendix. A monthly stormwater charge is calculated by multiplying the ERU ratio by the ERU rate. b) All Other Stormwater Class: The monthly stormwater fee is calculated for all other stormwater classes by dividing the estimated impervious area for a parcel by the average impervious area for the Tier 1 single- family residential stormwater class to determine the ERU ratio. The ERU ratio is then multiplied by the ERU rate to determine the monthly stormwater charge. See Table 2, in the Appendix for examples of an impervious surface. The impervious surface area shall be capped at 1,000,000 sq. ft. c) Delinquency: i. Pursuant to City Ordinance, Sec. 1-13a, b ̶ Clean Hands, no person or entity or owner shall be eligible to receive any city services, utilities, permits, licenses, or approvals if that person, entity, or owner owes outstanding payments to the city ii. Pursuant to City Code §110-305, all penalties, fines, and costs associated with enforcement of this chapter shall be liens on the property to the extent permitted by Title 25, Chapter 29 of the Delaware Code. 1.3 Purpose In conjunction with the implementation of the stormwater charge, the City has established a stormwater credits, grants, and appeals program. a) Credits The purpose of the stormwater credits program is to enable parcel owners to seek reduction in stormwater charges if specific stormwater management measures have been implemented. The onsite stormwater management measures need to significantly reduce the volume of runoff into the City’s stormwater system and/or enhance the water quality in the surface water bodies into which a parcel’s runoff discharges. Stormwater Credits are associated with the construction, operation, and maintenance of privately owned stormwater management facilities that complement the City’s stormwater management efforts and support the City’s stormwater management and surface water quality protection activities. b) Charge Adjustment Appeals The purpose of the charge adjustments appeals process is to enable customers to appeal any potential exceptions relating to parcel ownership, stormwater classification, and stormwater credit qualification. For more information about the appeals process, please see section 3.0, Stormwater Charge Adjustment Appeals, of this manual. 32

Item 4. Stormwater Charge Credits, Grants, and Appeals Manual 1.4 Definitions This section provides definitions for key terms relating to stormwater credits and the charge adjustments appeals process described in this technical manual. See also the definitions section of the City Code §110-301. All other stormwater classes: Refers to the various stormwater classes, except the single-family residential stormwater class. Appellant: Refers to the parcel owner or the owner’s authorized nominee who files an application for a charge adjustment appeal. Applicant: Refers to the parcel owner or the owner’s authorized nominee who files an application for a stormwater credit. Best Management Practices (BMPs): Best Management Practices are structural and/or non‐ structural stormwater management practices that are deployed in a property to control stormwater runoff and/or to improve the quality of stormwater runoff. Dwelling: Refers to a structure with one kitchen and one or more baths and bedrooms separate from the kitchen including houses, mobile homes, manufactured homes, apartments, and those attached to other dwellings or structures. Equivalent Runoff Unit (ERU): A unit of measure that is set to equal the median impervious area square footage of parcels of the Tier 1 single-family residential stormwater class. Equivalent Runoff Unit Ratio (ERU Ratio): Refers to the number of ERUs that are assigned to each parcel in the Single‐Family residential stormwater class, based on the tier assigned to each parcel. Impervious Area: The total square feet of hard surface areas including buildings, driveways, any attached or detached structures, and paved or hardscaped areas, or other surface areas that behave like an impervious area under wet weather conditions, that either prevent or restrict the volume of stormwater that can enter into the soil, and/or thereby cause water to run off the surface in greater quantities or at an increased rate of flow than what would have occurred under natural undisturbed conditions. 33

Item 4. Stormwater Charge Credits, Grants, and Appeals Manual Single‐family Residential Stormwater Class: Parcels with a single-family, detached, semi‐ detached or attached dwelling. Stormwater Charge: Refers to the monthly charge for stormwater management assessed to a parcel within the city based on the impervious area of the parcel to be billed on the associated cycle billing route for the service location. Stormwater Management Facility: Refers to an engineered stormwater control structure specifically designed to reduce the quantity of runoff, while also improving the runoff quality. Tier: The tier value that is assigned to each parcel in the Single‐Family Residential Stormwater Class, based on the parcel’s actual impervious area. Water Quality: Those characteristics of stormwater runoff from a land disturbing activity that relates to the chemical, physical, biological, or radiological integrity of water. Water Quantity: Refers to those characteristics of stormwater that relate to the rate and volume of the stormwater runoff resulting from land disturbing activities. 34

Item 4. Stormwater Charge Credits, Grants, and Appeals Manual 2.0 STORMWATER CREDITS 2.1 Objective The policies and procedures outlined for stormwater credits processes is designed based on the following key objectives: • Aid the City in meeting stormwater quality and quantity management, as well as flood mitigation needs. • Support the City’s NPDES Phase II permit compliance requirements. • Afford charge reduction opportunity for customers who reduce their burden on the stormwater system and services provided by the City through the operation and maintenance of stormwater best management practices. • Support equitable cost recovery of stormwater management costs. 2.2 Credit Policies The system of credits defined in this Stormwater Credits, Grants, and Appeals Manual (manual) is governed by the following policies: a) Credit Application Only parcels that pay for the maintenance of an onsite stormwater management facility are eligible to apply for stormwater quality/quantity credits. The Stormwater Credits Application (see Form C‐1 in the Appendix) and all supporting documentation must be filed by the applicant in writing to the Director of the Department of Public Works. The credit request may be filed any time but adjustments, if any, will be effective as stated in Section 2.2(h). of this manual. b) Types of Credits Quality Credits: Quality Credits are available to properties that pay into the maintenance of a stormwater management facility and/or directly own a stormwater management facility which was designed to effectively control pollutants in the runoff and to enhance water quality (see 2.2(c). of this manual) *. If water quality credits are provided, the City may at any time revoke the credits for non‐compliance with BMP maintenance standards. Quantity Credits: Quantity Credits are available to properties that control the rate of stormwater runoff contributed to the City’s stormwater system or surface water system (rivers, streams, etc.) *. Credits will not be provided for stormwater management practices that are under construction and/or are not fully functional and/or are not properly maintained. If quantity credits are provided, the City may at any time revoke the credits if the stormwater management systems are found to be poorly maintained and/or non‐functional. * (Subdivisions with an active HOA) 35

Item 4. Stormwater Charge Credits, Grants, and Appeals Manual c) Quality Credits Quality Credit up to 15% may be provided if the parcel owns and/or pays into the maintenance of stormwater management practices that infiltrate between 1 and 2.5 inches of runoff in accordance with the following increments: Figure 1- Quality Credit (%) According to Depth of Runoff Managed (Inches) Total Depth of Runoff Quality Credit Managed (Inches) (%) 1.5 5.0 2.0 10.0 2.5 15.0 Consideration for credits may be given to additional water quality best management practices at the discretion of the Director of Public Works. Applicants must document and demonstrate that the BMPs exceed applicable Delaware Sediment and Stormwater requirements via certified engineering documentation. d) Quantity Credits Quantity Credit is available to parcels that utilize onsite structural stormwater management measures such as retention or detention ponds, or other non‐structural practices to manage stormwater runoff. The applicant must submit certified engineering documentation that affirms the existence of a fully functioning stormwater management facility that is privately owned. The applicant must also submit a maintenance agreement for the stormwater management facility that affirms the maintenance is privately funded. Quantity Credit up to 10% may be provided to parcels where the post‐development peak stormwater discharge rates are managed to pre‐development peak discharge rates as follows: • Manage the 10‐year post development peak discharge to the 2‐year pre‐development peak discharge; • Manage the 25‐year post development peak discharge to the 10‐year pre‐development peak discharge; • Manage the 50‐year post development peak discharge to the 25‐year pre‐development peak discharge; • Manage the 100‐year post development peak discharge to the 50‐year pre‐development peak discharge. 36

Item 4. Stormwater Charge Credits, Grants, and Appeals Manual Design standards and criteria of the stormwater management structures must conform to the guidelines and design standards defined in Section 10.0 of the Delaware Sediment and Stormwater Regulations of Title 7 Natural Resources & Environmental Control Administrative Code as most recently issued by the DNREC Division of Soil and Water Conservation. e) Maximum Credits The maximum allowable stormwater credits for quantity reduction (Quantity Credits) is 10% of the ERU rate for the parcel seeking the credit. The maximum allowable stormwater credits for quality control (Quality Credits) is 15% of the ERU rate. The maximum aggregate stormwater credit for any individual parcel cannot exceed 25% of the ERU rate for the parcel. However, when special circumstances arise, such as a property infiltrating 100% of its stormwater, then the City may, at its discretion, provide up to a maximum of 50% credit. f) Application Fee A credit application will not be considered complete and will not be processed unless accompanied by a non‐refundable fee of $150.00 per parcel, along with all other required supporting documentation as outlined in this Stormwater Utility Credits and Appeals Manual. If the application fee check submitted is uncollectible, the Department of Public Works will terminate the technical review, until a valid application fee is credited. g) Renewal of Credits Any stormwater quantity or quality credit that is provided to a parcel is contingent on continued maintenance and operation of the private stormwater facilities or devices, as stipulated by the Director of Public Works. The City may revoke the stormwater credits at any time for non‐compliance. The approved credits are valid for a four‐year term, with the credits expiring on December 31st of the fourth year.

In the event all grant money is not awarded in any given year, special consideration will be given to community projects with several applicants. 5.0 STORMWATER CREDITS AND CHARGE ADJUSTMENTS EXAMPLES 5.1 Stormwater Credits The following examples illustrate the calculation procedures that would be applied in the assessment of monthly stormwater charges if stormwater credits are approved for a parcel. The examples are based on a Tier 1 Single-Family Residential Stormwater Class parcel, a monthly ERU ratio of 1, multiplied by the stormwater charge of $6.00, equaling $6.00/month. d) Quality Credit The following example shows the credit amount calculation and the billable monthly stormwater charge for a parcel that is granted a Quality Credit only. Total original monthly stormwater charge: $6.00 Approved Quality Credit: 15% Applied Quality Credit Adjustment: $6.00 - (15% x $6.00) = $5.10 Total Billable monthly stormwater charge: $5.10 Quality Credit Amount Issued to the Parcel: ($6.00 ‐ $5.10) = $0.90 e) Quantity Credit The following example shows the credit amount calculation and the billable monthly stormwater charge for a parcel that is granted a Quantity Credit only. Total original monthly stormwater charge: $6.00 Approved Quantity Credit: 10% Applied Quantity Credit Adjustment: $6.00 - (10% x $6.00) = $5.40 Total Billable monthly stormwater charge: $5.40 Quantity Credit Amount Issued to the Parcel: ($6.00 ‐ $5.40) = $0.60 47

Item 4. Stormwater Charge Credits and Appeals Manual 5.2 Storm Water Charge Adjustments Appeal The following example illustrates the calculation procedures that would be applied in determining a revised impervious surface estimate in the case of an All Other Stormwater Class parcel that files an adjustment appeal seeking impervious area variance, and in determining the revised monthly storm water charge. If a Single-Family Residential parcel is misclassified, please fill out form A-1 in the Appendix and if approved, your rate will equal that of the appropriate Tier. For All Other Stormwater Class adjustments fill out form A-2 and see below for example calculations. b) Inaccurate Impervious Area Estimation for All Other Stormwater Classes The calculations for this example are based on the following assumptions: • Non‐residential parcel with a Gross Parcel Area of 190,000 sq. ft. • Impervious Area for this parcel is estimated using impervious coverage files from the Office of State Planning Coordination. • The property consists of a building that is 100,000 sq. ft.; sidewalks of 10,000 sq. ft.; gravel parking lot of 50,000 sq. ft.; and grass area of 30,000 sq. ft. For a total of 160,000 sq. ft. of impervious surface Individual runoff coefficients are assigned to the various land cover delineations as shown in Figure 2. Multiplying the individual runoff coefficient by the land cover delineation equals the adjusted, calculated impervious area in sq. ft. Figure 2- Calculation of Impervious Area Based on Actual Land Cover Delineation Land Cover Area (Sq. Ft.) Individual Calculated Delineation Land Cover Impervious Runoff Area (Sq. Ft.) (1) (2) Coefficients (4)= (2)x(3) (3) Structures 100,000 1.00 100,000 Asphalt 10,000 0.95 9,500 Loose Gravel 50,000 0.50 25,000 Grass 30,000 0.30 9,000 Total Property 190,000 143,500 Gross Area 48

Item 4. Stormwater Charge Credits and Appeals Manual Original monthly charge calculation: • Average impervious area for Tier-1 Single-Family Residential Stormwater Class is 1,400 sq. ft. • 160,000 / 1,400 = ERU ratio of 114.29 • ERU ratio of 114.29 x ERU rate of $6.00 = $685.71 per month. Revised Monthly Stormwater Charge Calculation: • Total Impervious Area Based on Land Cover Delineation (Impervious examples on Table-2) = 143,500 sq. ft. • Total revised ERUs: 143,500 sq. ft. / 1,400 sq. ft. = 102.5 ERUs • Total revised monthly stormwater charge: 102.5 ERUs x $6.00 = $615 49

Item 4. 63

Item 4. Stormwater Utility Making Dover Stormwater Smart! 64

Item 4. What is the Stormwater Utility? The Stormwater Utility is a monthly stormwater charge that will be issued as a general bill. It was implemented to address increasing NPDES (National Pollutant Discharge and Elimination System) permit costs as well as personnel, operations, and capital costs. Compliance with NPDES permit is required by State and federal agencies (EPA and DNREC). 65

Item 4. How will rates be established? Rates are based on the total impervious surfaces on a parcel. Residential calculations are also correlated to zoning. This will be standardized using ERUs (Equivalent Runoff Units). 66

Item 4. ERU= Equivalent Runoff Unit 1 ERU= 1,700ft2 of impervious surface 67

Item 4. Residential Rates: Tier-based System Tier 1 RG-3, RG-4, TND 1.0 ERU Monthly charge: 1.0 ERU * $6.00 = $6.00 Tier 2 RM-1, RM-2, RG-1, RG-2, R-7 1.4 ERUs Monthly charge: 1.4 ERU * $6.00 = $8.40 Tier 3 RG-5, R-8, R-10, R-15, R-20 2.2 ERUs Monthly charge: 2.2 ERU * $6.00 = $13.20 68

Item 4. Commercial Rates Commercial rates will be determined solely by impervious surfaces* ** To calculate the rate for a commercial property, the square footage of impervious surface on the property will be divided by the size of an ERU (1,700ft2). This will determine how many ERUs the property produces. The calculated number of ERUs will then be multiplied by the price of one ERU. This will determine the monthly payment.
