. Why establish a Stormwater Utility o Dedicated revenue o Regulatory Compliance (MS4, TMDL) o Improve Water Quality o Protect Water Quality o Flood Control / Resiliency o Aging Infrastructure o Capital Improvement Needs . Enterprise Fund vs. Taxes/Assessments o Reliable Source o Consistent Revenue o Equitable – links to runoff to manage o User-based much like other Utilities Keys to Successful Utility . Cost of Service tied to Level of Service . Understandable and Supported by Public . Tangible Results obvious to Public . Rate is equitable to the amount of runoff to be managed o Little runoff = little fee o Large runoff = large fee DETERMINATION OF LEVEL OF SERVICE How are Service-Fees Assigned?

. Normally based on impervious area o Mainly artificial structures that reduce the infiltration of rainfall into the ground. o Roads, parking lots, rooftops, driveways, sidewalks, compacted soils. . Equivalent Residential Unit (ERU) o The average amount of impervious area on a single-family property. o Used as billing standard. . Stormwater Rate – rate paid per ERU. . Stormwater Bill – stormwater rate times the number of ERUs. Utility Billing Basis

Public streets, ROW, drainage infrastructure not charged, considered part of the drainage system. Example Utility Billing Calculation Other Considerations

. Who will be responsible for billing? o Existing utility or taxing authority. . What remedies are available for non-payment of the fee? o This can depend on who is sending out the bill. . What about credits and exemptions? o Credits should only be given for actions that avoid a cost to the utility. o Any exemptions have to be subsidized by other rate payers. 03: Review of Proposed Stormwater Rate Consulting Services TASK 3: Project Initiation and Data Collection and Review

. Access to County’s existing stormwater GIS data. . Current Stormwater Program operating budget and Capital Improvement Program. . Access to County’s existing GIS data layers including land use, planning, and service area boundary. . Estimated operation and maintenance (O&M), administration, and repair and replacement budgets. . Historical and current financial records, including any financial audits, monthly operating reports, or budgets. . HDR and PRMG will provide the County with a detailed request of repaired information/data as part of Task Deliverables. TASK 4: Identify Stormwater System Revenue Requirements

. Identification of stormwater utility expenditures for O&M, administration, capital improvements, and asset replacement. . Meet with County to review Stormwater Management Program needs and funding sources including available cash balances or currently dedicated funding sources other than utility rates (funding sources may include ad valorem taxes, grants and/or dedication of gas taxes). . Develop a Capital Funding Plan. . Provide the County with a Stormwater System Test Year Revenue Requirements. TASK 5: Design Stormwater Rate Alternative

. Develop alternative rate structures to recover the costs identified in Task 4. . Define an Equivalent Residential Unit – for use in rate application methods. . Determine impacts of various rate structure alternatives to both residential and commercial/industrial parcels. . Evaluate alternative stormwater governance/billing options such as non- ad valorem assessments versus stormwater utility billing. . Provide a table that outlines and summarizes the pros and cons of each rate alternative. TASK 6: Stormwater Utility Report

. Develop a Stormwater Rate Report that will summarize the various alternative rate structures, including methodologies, assumptions, and considerations used during the course of development. . Attendance at two Board of County Commissioners meetings to present and discuss the alternative utility rates and the effects of such rates on the residential and commercial/industrial properties. 04: County Overview of Existing Stormwater Program

The model, currently in use by considerations should the City decide to move forward the City, allows the City to model a variety of “what-if” with a utility. scenarios by changing growth rates, the mix of capital projects and timing, sources of capital and operational Stormwater Utility Creation funding, and other variables to ascertain their effect on a City of Buda | Buda, TX 5-year forecast of expenses, revenue requirements, and HDR developed a stormwater utility for the City of Buda needed utility rates. utilizing data from recent aerial photography. This project included determining the impervious cover on over 10 Stormwater Utility Financial Planning Model square miles of land within the City limits, matching City of Chester | Chester, PA parcel addresses to City billing accounts, developing a HDR has worked closely with Chester City staff to policy manual, and developing ordinances for the creation develop a utility rate model that is capable of computing of the utility. This project also involved working closely rates for different revenue scenarios. Some of the with the City Council to educate not only them, but also scenarios have included differing revenue requirements, the public, about the benefits of creating a stormwater rate structures, and collection rates. In addition, HDR utility. This was accomplished, in part, by holding several has presented information to the City on cost allocation public meetings throughout the City. among different customer classes and options for billing.

Stormwater Rate Study and Connection Fee of parcels and level of impervious area for an equivalent City of Issaquah | Issaquah, WA unit for rate setting purposes. The development of As part of the comprehensive water, sewer, and the stormwater connection fee included reviewing the stormwater rate study completed by HDR for the City, existing stormwater assets (infrastructure) and future the stormwater rates and general facility charge (e.g., improvements necessary to meet new growth on the connection fee) was also updated. The rate study system. Given the City’s system has two distinct areas, reviewed the City’s costs of providing stormwater one already having separated sewer and stormwater, and services across the service area. A key element of the one that does not, HDR worked with City staff to review study was to develop a capital funding plan for future alternative connection fee approaches to address the improvements to the stormwater system to meet the differences in development requirements in each area. necessary operating and capital needs. The rate structure The connection fee was developed to reflect the City’s was also reviewed and is based on an impervious area goals and reflect the costs associated with each area. approach with each residential customer representing 2,000 square feet (SF) of impervious area. All other Stormwater Rate Study customers are charged on a per equivalent basis using the City of Stockton, Municipal Utilities Department | 2,000 SF of impervious area. While reviewing available Stockton, CA data, it was determined that the 2,000 SF of impervious HDR completed a stormwater rate study for the City’s area represented a typical single-family customer. HDR Municipal Utilities Department. Key to the study was the reviewed the City’s current connection fee methodology development of a revenue transition plan to adequately and recommended and updated the fee based on fund annual operating and increased capital costs related the current capital improvement plan and existing to meeting the NPDES permit requirements. A capital stormwater assets. A key component of the analysis funding plan was developed to determine the funding of was determining the contributions made through grants capital through a mix of revenues and long-term debt. or other funding sources that are excluded from the fee HDR also worked with City staff to review the impervious calculation. Based on the City’s funding records, the area associated with a typical single family customer to contributed assets were backed out of the calculation of establish an Equivalent Residential Unit (ERU), which was the charge. This was importation, as a significant portion used as the basis for determining the number of ERUs of the City’s system was funded through developer for non-residential customers. As part of the study, the agreements and not by the City. The stormwater study customer classes of service were also reviewed and a recommendations were presented to the Council discussion on various residential customers took place committee for review and discussion and the City Council to determine if separate rates based on impervious area for adoption. HDR provided a report to the City detailing categories should be implemented. After discussion the analyses completed. with City administration, it was determined that a single residential class would be established based on Surface Water Rate Study the calculation of average impervious area. All other City of Everett | Everett, WA customers would be charged on a per equivalent unit At the present time, the City’s sewer rates include basis as compared to the residential impervious area. the costs associated with both the sewer system and HDR provided public outreach assistance through stormwater system. Given this, the City was interested multiple meetings at various noticed events to help in developing a separate stormwater utility and a set of educate and inform the public on the need for the rates and connection charges. The starting point for the stormwater rate adjustment. stormwater revenue requirement was to separate out the stormwater costs from the sewer budget and determine if any additional costs were included in other departments (e.g., street sweeping, etc.) and include them in the stormwater analysis. Next, a capital funding plan was developed to meet the overall capital improvement needs of the stormwater system. This included a significant level of capital to separate a portion of the City’s system from the sewer system. At the same time, alternative rate designs were reviewed for charging customers and, in particular, the use of impervious surface area for billing purposes was reviewed in great detail to develop an equivalent unit for establishing the rates. The City developed GIS data to determine the number
