July 12, 2019 Mr. John Lyons, P.E., PSM Public Works Administrator Hillsborough County 601 E. Kennedy Blvd. Tampa, FL 33602 Subject: Stormwater Management Program Business Plan and Rate Study Dear Mr. Lyons: Public Resources Management Group, Inc. ("PRMG"), Applied Sciences ("AS"), and Government Services Group, Inc. ("GSG"), collectively, (the "Project Team") have prepared a Stormwater Business Plan and Rate Study (the "Business Plan") for Hillsborough County, Florida (the "County"). The Business Plan includes a review of the County's current stormwater management organization, governance, operations, service levels and costs of service and rate structure, as well as developing a recommended business strategy to address the County's stormwater management funding requirements. The Business Plan has been developed in conjunction with County staff and this report summarizes the results of our analyses considerations, assumptions and recommendations, which is submitted for your consideration. To develop the proposed Stormwater Business Plan and rates, we have relied upon certain information and data provided by the County including the County's Annual Budgetary Reports; records maintained in the maintenance work order system, information gathered through field interviews with County staff, stormwater billing statistics developed from the County's property tax records and GIS System, stormwater asset records, and the current capital improvements expenditure plan. To the extent our analyses use certain data and information obtained from the County in the preparation of this report, we have relied upon such information to be accurate and, consequently, we make no representations regarding its accuracy. The proposed Stormwater Business Plan and Rate Study presented herein is intended to meet certain goals and objectives. The two key objectives of the Business Plan were to: 1) develop a proposed organizational and operational strategy to provide sustainable stormwater services; and 2) develop a proposed rate alternative that funds the sustainable operating and capital expenditure requirements of the Stormwater System (the "System") and are fair and equitable based on industry standards and ratemaking methods that best meet the needs of the County. Underlying these objectives, the primary goal of the Business Plan is to maintain and improve stormwater management services provided by the County. This report summarizes the results of the Project Team's investigations and analyses and outlines our recommendations and conclusions for the County's consideration.
Mr. John Lyons, P.E., PSM Hillsborough County July 12, 2019 Page 2
The Project Team appreciates the opportunity to be of service to the County and would like to thank the County staff for the valuable assistance and cooperation that we received during the preparation of this study. Respectfully submitted, Public Resources Management Group Henry L. Thomas Senior Vice President HLT/dlc Attachments

SECTION 1 REVIEW OF EXISTING STORMWATER MANAGEMENT PROGRAM
1.1 Background
Hillsborough County (County) is a coastal community located midway along the west coast of Florida. The County boundaries embrace 1,048 square miles of land and 24 square miles of inland water for a total of 1,072 square miles. With the largest bay in Florida opening to the Gulf of Mexico, the County's coastline spans 76 miles. The major riverine systems running through the County, such as the Hillsborough River, Little Manatee River, and Alafia River, combine to total more than 550 miles across 17 defined major watersheds. The unincorporated area encompasses 84% of the total county area. According to the latest population estimate from the University of Florida's Bureau of Economic and Business Research, the county's April 1, 2017 total population was 1,379,302 making it the fourth most populous county in the state. Of this population, 905,007 or 68% live in the unincorporated area of Hillsborough County (County). Pursuant to Federal and State regulatory requirements, the County's Stormwater Management Program is responsible to regulate, maintain, and manage stormwater run-off within the County. As such, the County's Stormwater Management Program was established to: 1) reduce undesirable stormwater impacts through stormwater runoff reduction and pollution prevention strategies; 2) maintain the integrity of the County's stormwater infrastructure; 3) minimize flooding; 4) plan for and implement future Stormwater System improvements; and 5) ensure compliance with Federal, State and Local stormwater management rules and regulations. These regulatory requirements include federally mandated National Pollution Discharge Elimination System ("NPDES") permit requirements. The County's NPDES permit regulates what can be discharged into freshwater areas and delegates compliance enforcement to the County and requires that the County control and reduce pollutants entering the Stormwater System from residential and commercial properties. Through the County's Stormwater Management Program, Hillsborough County Public Works Department performs the maintenance, rehabilitation, and construction of the local stormwater conveyance and storage systems to provide public safety, asset preservation, and regulatory compliance. The County is committed to maintaining a sustainable level of service regarding stormwater quantity, stormwater quality, and stormwater management system maintenance throughout unincorporated Hillsborough County. The work performed by the County directly benefits residents and contributes to improved water quality in freshwater wetlands and the improved water quality of Tampa Bay. The County is committed to continue to meet these level of service criteria on an aging and increasingly stressed Stormwater System. Maintenance activities and ongoing improvements to the Stormwater System provide a direct benefit to existing residents as well as meeting the needs of a growing population. According to a study published by the Planning Commission in November 2017, the County is growing by more than 24,000 new residents every year. With little vacant land in the northwest portion of the County, high growth areas are concentrated in the south and south-central areas. As a result of the population growth trend increasing, the amount of stormwater assets and associated maintenance needs across the entire County are also increasing as the associated development

directly impacts the County stormwater infrastructure investment as well as the necessary level of ongoing inspections and maintenance activities. Stormwater Fees are typically established to provide a dedicated revenue source to fund the costs of stormwater management. While the County's current Stormwater Fee is not sufficient to provide revenues to fully fund stormwater management costs, the existing fee application structure that was implemented in 1991 also does not reflect the stormwater service area's current property characteristics and current industry practices used in Florida to establish the basis for Stormwater Fees. To partially fund the County Stormwater needs, a Stormwater Management Revenue Fund was established in 1991, including implementation of a Stormwater Fee. The Stormwater Fee is billed as a Non-Ad Valorem Special Assessment levied on the annual property tax bill and has been primarily used to help fund the stormwater capital reinvestment program. The capital reinvestments funded by the Stormwater Fee are primarily focused on renewal, replacement and rehabilitation (R&R) of existing Stormwater System assets located throughout the Stormwater System's service area. As such, the current fee level only funds a portion of the Stormwater Management Program requirements, specifically the R&R projects identified in the Capital Improvement Program (CIP). The Stormwater Fee does not produce sufficient revenue to fund the remaining operating and maintenance activities, such as inspection, maintenance, project management, administration, planning, etc. To compensate for the Stormwater Fee revenue deficit, the Stormwater Management Program is reliant on supplemental contributions from Ad Valorem Taxes, Community Investment Tax, and State and Federal grants to fund the remaining costs. In addition to these funding challenges, the County's stormwater funding requirements have outpaced the available revenue, and the backlog of stormwater maintenance needs and unfunded capital requirements continues to grow now more than ever. 1.2 Stormwater Management Program Utility Goals and Objectives
The County has requested that a Stormwater Business Plan be developed that identifies the total cost of the County Stormwater related activities. Furthermore, the County has requested that the Business Plan include estimates of alternative Stormwater Fee levels that would result in a Stormwater Management Program that is self-sufficient, meaning it has a dedicated funding source with a revenue stream adequate to meet all of the program needs related to facility inspections, operations and maintenance, capital facility renewals and replacements, regulatory compliance, and planning, including recognition of the estimated cost of enhancing the level of stormwater maintenance activities and capital reinvestment to achieve a sustainable Stormwater Management Program. In addition to evaluating revenue requirements to fully fund the Stormwater Management Program, and potential enhancements to maintenance activities and capital reinvestment related to asset preservation, another significant objective of this study involves analyzing and recommending updates to the existing rate method used to develop the Stormwater Fee. This includes developing a fair and equitable rate structure based upon current property characteristics and industry standards.
-3-
The County's current rate structure for stormwater service is generally based on the impervious area per equivalent residential unit ("ERU") approach. An ERU, which was established by County Ordinance adopted in 1991, is defined as the average impervious area of a single-family residential home or 1,800 square feet. Impervious area includes items such as buildings, driveways, parking lots, swimming pools, and other hard surfaces that prevent stormwater runoff from being absorbed into the ground. Under the County's Stormwater Ordinance, multi-family residential properties and mobile homes are billed 0.5 ERUs per unit and for non-residential or general properties, each property's impervious area is measured and then divided by 1,800 square feet to determine the number of equivalent residential units to be billed for that property. A major task conducted as part of the rate structure analysis was to evaluate the current basis for calculating ERUs based on current property characteristics. 1.2.1 Scope of Services, Project Goals, and Objectives
The Business Plan has been prepared by a team of consultants with the necessary expertise to assist the County with the preparation of Stormwater Utility Business Plan and Rate Study. The consultants contracted by the County include Public Resources Management Group, Inc., (PRMG), Applied Sciences (AS), and Government Services Group, Inc. (GSG), collectively (the "Project Team"). The purpose of the Business Plan is to evaluate the County's Stormwater Management Program's goals and objectives, review the County's stormwater related organizational structure and staffing, prepare a cost of service analysis, evaluate stormwater rate structure alternatives, review of the projected expenditure needs associated with ensuring sustainable stormwater operations, and recommend a Stormwater Management Business Plan that meets the County Stormwater program demands, goals and objectives. The results of the Business Plan evaluation are described in the sections that follow.
The primary goal of the Stormwater System Business Plan and Rate Study is to estimate the cost of Stormwater Program activities including enhanced levels of service and recommend a fair and equitable rate structure to financially support the County's Stormwater Management Program. This goal included the following supporting objectives:
1. Identify the Divisions and Agencies that perform stormwater related services, and establish the type of support and level of involvement;
2. Estimate the current and future revenue requirements for the Stormwater Management Program;
3. Develop a fair and equitable rate structure to collect revenues based on industry standards and practices to best meet the County's objectives while considering data maintenance efforts and administrative burdens; and
4. Facilitate future program planning to develop a self-sufficient Stormwater Management Program and organizational strategy with sufficient revenue to fund the capital improvement program, field operations and maintenance, and support services needs to maintain and enhance stormwater services provided by the County.
-4-
In order to meet the intent of the Scope of Services and project goals and objectives, the Project Team performed the following activities, which are expanded upon in detail in this report:
● Met with County to refine the project scope to more clearly align with the County's goals and objectives;
● Reviewed County adopted reports and documents that define the County Stormwater Management Program, and datasets that support the County Stormwater Asset Inventory. These include, but are not limited to:
o Fiscal Year 2019-2024 Stormwater Capital Improvement Program;
o Fiscal Year 2018-2019 Adopted Public Works Budget;
o Stormwater Asset Inventory Geodatabase July 2017;
o County NPDES Permit (July 2016) and Annual Report (July 2017); and
o Draft 2018 and Adopted 2008 Unincorporated Hillsborough County Comprehensive Plan – Stormwater Management Element.
● Review of the current adopted Stormwater Utility Rate Structure
● Review of the County's Public Works Organizational Charts as of March 29, 2018
● Interviews with Divisions and Service Section staff members to understand stormwater roles and responsibilities, and level of involvement regarding stormwater-related maintenance activities
● Review of financial stormwater reporting options
● Cost of service analysis for related activities
● Review of the property and characteristics within the service area
● Impervious area sampling for Stormwater System customer classifications to evaluate Stormwater Fee application criteria
● Preliminary rate analysis based on revenue neutral rates
● Five-year financial forecast
● Analysis of enhanced sustainable funding plan
● Development of rate structure alternative and proposed rates
● Summary of stormwater industry credit practices

1.3 Existing Capital Improvement Program
As part of the Stormwater Business Plan, the Project Team reviewed the Fiscal Year 2019 through 2024 Capital Improvement Program (CIP) as well as the Fiscal Year 2018-2019 Adopted Public Works Budget. The Hillsborough County Stormwater CIP prioritizes planning, design, and construction of Stormwater System projects that provide both water quantity and water quality benefits to the community and environment. The County has developed, and continues to maintain, a comprehensive Watershed Master Plan that is used to establish the existing flood level of service criteria, as well as water quality projects related to regulatory compliance and to meet environmental goals established in the Comprehensive Plan. The County has developed these plans for each of its seventeen watershed basins, which are routinely updated to keep up with changing County growth and development, as well as improvements to modeling techniques, increases in accuracy and resolution of datasets, and the evaluation of current best management practice (BMP) alternatives. Under the plan, the entire County (1,072 sq. miles) is divided into 17 watersheds (basins) and further subdivided into 7,000 sub-basins. As previously mentioned, these master plan studies look at water quantity, water quality and the natural watershed system and its functions. The plan identifies areas with inadequate conveyance systems or poor water quality with the objective of developing cost effective and technically feasible solutions. Flood control project evaluations take into consideration the following factors: frequency of flooding, the category of the road subject to flooding (local/arterial/collector road), the number of structures flooded, stormwater asset conditions (groundwater table, erosion/siltation and structure) and the potential of obtaining available grant funds. The County also maintains a separate list of non-watershed related neighborhood stormwater needs. Criteria for neighborhood stormwater projects is similar to criteria for watershed master plan projects, with the exception that environmental issues and the availability of matching grant funds are not included in the evaluation. Water quality or natural system projects are evaluated based on concerns identified by the Florida Department of Environmental Protection, or the County related to the sub-watershed segment of "impaired waters/water bodies," the criteria of water quality parameters and the benefits of a natural system. Both engineers and environmental scientists within the Stormwater Services Section of the Public Works Department contributed to this evaluation process. 1.4 National Pollutant Discharge Elimination System Permit Summary and Existing
Maintenance Level of Service
The Project Team reviewed the Hillsborough County National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) permit (FLS000006-004), a Major Facility classified permittee. The permit authorizes the discharge of stormwater to waters of the State, in accordance with the approved Stormwater Management Programs (SWMPs), effluent limitations, monitoring requirements, and other provisions as set forth in said permit.
-6-
In summary, the permit document establishes or defines what discharges are authorized under the permit, the requirements for the Stormwater Pollution Prevention and Management Program implementation controls and activities, the schedules for implementation and compliance, system monitoring and annual reporting requirements, and other specific conditions of the permit. The NPDES Permit establishes a standardized inspection and maintenance activities schedule based on stormwater asset type, which can be found in Table II.A.1.a of the Hillsborough County Final MS4 Permit document, issued July 11, 2016. The County stormwater asset inspection and maintenance schedules, according to the issued permit, are summarized in Table 1 below. Note that the maintenance is generally listed to be as needed based on inspection to ensure proper operation. These inspection and maintenance frequencies are considered to be the County's current Maintenance Level of Service.
Table 1 Inspection and Maintenance Schedule for Stormwater Assets
Asset Type Inspection Maintenance
Stormwater Facilities; Dry Retention and Wet Detention (New System) Annually first two years of operation
As needed based on inspection to ensure proper
operation
Stormwater Facilities; Dry Retention and Wet Detention (No Issues) Once every three years
Stormwater Facilities; Dry Retention and Wet Detention (Chronic issues) Annually until issues corrected
Underdrain filters, Exfiltration Trench, and Grass Treatment Swales Same as Stormwater Facilities (above)
Pollution Control Boxes Quarterly, unless determined otherwise
Pump Station Semi-annually, or more as needed
Alum Injection Monthly, unless observed otherwise
Major Outfalls Annually unless determined otherwise
Control Structures Same frequency as type of system associated with structure
Pipes and Culverts 10% of structures per year; At least one over two permit cycles (every 10 years)
Canals part of MS4 Annually
Inlets and Catch Basins 10% of structures per year; At least one over two permit cycles (every 10 years)
Ditches, Swales, and Other Conveyance 10% of structures per year; At least one over two permit cycles (every 10 years)

In addition, the Project Team reviewed the Hillsborough County NPDES MS4 Annual Report for August 2016 through July 2017 (the "Annual Report"). The Annual Report contains information ranging from fiscal analysis, to maintenance activities, development review, flood control projects, and environmental and water quality monitoring and TMDL compliance. The Annual Report summarizes statistics regarding the number of significant development reviews, litter control activities, maintenance services units, number of flood control projects, public outreach activities, illicit discharge prevention, environmental activities, and Total Maximum Daily Load (TMDL) monitoring and reporting status update. The Annual Report also includes a summary table of the inspection and maintenance activity for the Stormwater Assets over the 2016-2017 NPDES Reporting period. These reported inspection and maintenance records appear to meet or exceed the maintenance level of service established in the permit document. The metrics provided herein will be considered when analyzing and recommending a future maintenance level of service for the proposed stormwater management program. The Stormwater Asset Inventory and Inspection and Maintenance Records have been summarized in Table 2 below. The County stormwater asset inventory database was provided by the County on June 14, 2018, which came from the operations and maintenance group, and the totals were determined to be comparable with what has been reported in the Annual Report.

As for water quality, data was collected at more than 225 individual water bodies and over 3,261 sampling site locations. Several agencies contribute to data collection efforts. Data sources include Hillsborough County Public Works Department Environmental Services, Environmental Protection Commission of Hillsborough County, University of South Florida, and the University of Florida LAKEWATCH program. Data collected by these agencies are uploaded to the Hillsborough County Water Explorer (www.hch2o.org) which serves as a repository for water quality and other data collected in Hillsborough County. Through discussions and interviews with the staff of the Stormwater Operations and Maintenance Service Units, there are challenges in meeting the routine inspection and maintenance scheduling. Between the sheer number of assets compared to the number of maintenance staff, combined with the number of work orders being placed and urgent/priority service requests, the service units on a whole are operating under a more reactionary, rather than proactive condition. There are also certain known problem areas within the system that require frequent attention and service during the wet season. Each unit has identified a backlog for work orders as well as routine asset inspection and maintenance schedules. The common objective expressed by each of the service units is to catch up on service requests and allow the service units to operate under a sustainable level of service target with a more proactive maintenance and capital reinvestment approach. Recommendations regarding the County's Stormwater Maintenance Level of Service are included in Section 2 along with estimates of expected costs and Stormwater Fees in Section 3 to meet the cost of service requirements of the proposed future stormwater management program. 1.4.1 Stormwater Management Program Funding Sources
The Stormwater Management Program relies on two primary sources of revenue:
● Unincorporated County Ad Valorem Assessment, utilized to fund operations and maintenance as part of the Public Works Department budget; and
● Stormwater Utility Non-Ad Valorem Special Assessment (Stormwater Fee), used to fund capital projects and respond to regulatory requirements.
Historically, the Ad Valorem Funding and Stormwater Non-Ad Valorem Special Assessments have been leveraged with non-recurring supplemental funding including:
● Community Development Block Grants (CDBG)
● Cooperative Funding Agreements with the Southwest Florida Water Management District (SWFWMD)
● Florida Department of Environmental Protection Grants
● Federal Emergency Management Agency Grants
● Community Investment Tax (CIT)
Of the revenue sources that have been utilized historically, the Stormwater Fee is the only recurring, specifically dedicated funding source. In order to meet the Stormwater Management
-9-
Program's goals and objectives, the County should consider increasing the Stormwater Fee levels in an effort to create a viable and sustainable revenue source able to fund the expenditure requirements of all essential Stormwater Management Program functions. These functions include stormwater operation and maintenance activities, capital project implementation, regulatory compliance, in addition to administrative, management, and support activities. This will allow the Stormwater Management Program to operate as a self-sufficient program without having to compete against other essential County programs funded by the Unincorporated Area General Fund.
1.4.2 Current Utility Rate Structure
The County's existing the Stormwater Utility Assessment Rate Structure has five customer classifications:
● Residential: Includes all single-family residential defined parcels with structures
● Multi-Family: Includes Townhomes, Condominiums, duplexes, and triplexes
● Mobile Home: Includes all mobile home parcels and mobile home/RV parks
● Improved Agricultural: Includes agricultural classified parcels with residential structures
● Non-Residential: Any developed parcel that does not fall into the previous four categories, such as commercial businesses and institutionally-owned properties
The current rate structure is assessed to these categories based on the currently adopted annual Stormwater Fees as shown in Table 3 on the following page.
Table 3 Hillsborough County Existing Stormwater Fee Summary
Category Annual Stormwater Fee
Residential Single-Family $42.00 per single family residence
Multi-Family $21.00 per dwelling unit
Mobile Home/RV Park $21.00 per dwelling unit
Improved Agricultural $42.00 per property
Non-Residential $0.035 per 1.5 square feet of impervious area per year
Stormwater rates are generally applied to each property's equivalent residential units (ERUs). For the purpose of the stormwater rate structure evaluation, the ERUs have been derived for each category based on the current rate structure. The County's ERU basis, which was derived from the annual Residential Rate of $42 divided by the non-residential rate of $0.035 per 1.5 square feet, is equivalent to 1,800 square feet of impervious area per ERU.
-10-
Under the current rate structure, the Residential Single-Family Stormwater Fee is the basis for equivalent single-family residential units (ERU), with an assumed value of 1.0. The Multi-Family and Mobile Home residential categories are assessed based on an ERU value of 0.5. Improved agriculture parcels, or agricultural parcels with structures, are charged an ERU of 1.0. Each non-residential property has a unique ERU value based upon the actual square feet of impervious surface area for the property. 1.4.3 Alternative Billing Methods
Stormwater utilities in Florida typically bill for services through the application of either a stormwater user fee as part of the utility bill or through a Non-Ad Valorem Special Assessment. Generally, based on Florida Statutes, in order to fall within the legal requirements of a special assessment billing approach, the amount of the assessment must be commensurate with a special benefit or an increase in the value of the assessed property. Stormwater services billed through a monthly user fee are typically based only on the estimated run-off burden caused by the property. Based on the most recent survey of stormwater utilities prepared by the Florida Stormwater Association, sixty-six percent (66%) of the stormwater utilities generate revenues from monthly user fees and twenty-nine percent (29%) utilize Non-Ad Valorem Special Assessments. Under the monthly user fee approach, the "run-off burden" caused by the property is typically based on methods that estimate the amount of stormwater run-off generated by a property. Approximately sixty-nine percent (69%) of stormwater utilities who charge a user fee use impervious area as the basis for estimating a specific property's stormwater "run-off burden", while fourteen percent (14%) use both gross area and impervious area to establish the basis for charging Stormwater Fees. With this background, it can be concluded that the use of special assessments is more restrictive as to how stormwater costs can be levied to individual properties, since a special benefit related to stormwater facilities must be demonstrated while monthly user rates typically reflect system-wide rates based only on the estimated stormwater runoff generated by the property. These concepts are particularly germane to the recovery of costs associated with new capital facilities that can vary significantly for different water sheds or basins within a given jurisdiction and for which it may be difficult to demonstrate a County-wide benefit. For stormwater utilities in Florida that rely on the user fee or "run-off burden" approach, only three percent (3%) of the systems surveyed recently by the Florida Stormwater Association report that they charge fees for capital costs based on a "zone-of-benefit" approach. Accordingly, ninety-seven percent (97%) recover stormwater costs, including the cost of capital projects on a system-wide basis. However, there is nothing to preclude adopting a capital-related Stormwater Fee by basin. The County should establish a rate methodology that best suits the stormwater expenditure needs and the philosophy and goals of the community, recognizing that the Non-Ad Valorem Special Assessment Billing Method may require basin-specific assessments related to certain major capital improvements implemented in the future.
-11-
Table 4, below, provides a comparison of the advantages and disadvantages of the non-ad valorem special assessment bill collection method versus the utility bill collection method.
Table 4 Billing Methodology Pros and Cons
Non-Ad Valorem Assessment Method Utility Bill Method
Pros • Highest collection rate (95 – 98%)
• One bill with all charges
• Use tax roll data from PA
• Revenue received within 6 months of start of fiscal year
• Deadlines set by local government
• Timeframe set by local government
• Easier to charge exempt property
• May be able to use for government property
Cons • Strict statutory requirements regarding public notice
• Strict statutory timeframes
• Cannot use for government property
• May not allow for County-wide rates related to specific capital projects
• Difficult to correlate utility accounts to property uses (methodology issues)
• Collection issues regarding non-payment
• Utility bill gets crowded
• May miss property without utility account
• Revenue received on monthly basis
Set forth on Figure 1, on the following page, is a summary of stormwater billing methods used by a sample of Florida cities and counties. As shown in the summary, counties typically bill Stormwater Fees based on the Non-Ad Valorem Special Assessment method. Based on discussions with the staff of the Florida Stormwater Association, this is primarily due to the fact that many County properties do not have utility accounts and the difficulty of correlating utility accounts to parcels.

1.4.4 Financial Reporting Options
Based on discussions about identifying, documenting and accounting for the expenditure requirements of Hillsborough County's (the "County") stormwater utility system, we have compiled a brief comparison of financial reporting methods implemented by Stormwater Systems in other communities. Table 5, on the following page, summarizes the financial reporting approach for each of the following jurisdictions with service populations equal to or greater than 150,000:

As shown above, most of the surveyed communities use either an Enterprise Fund or a Special Revenue Fund to account for the annual stormwater revenues and expenditures. Like the County, a few of the communities also account for the cost of certain stormwater activities and transactions within the Public Works Department of the General Fund. Within the financial framework of governmental accounting, three (3) categories of financial funds are generally identified as follows: ● Governmental Funds including:
o General Fund
o Special Revenue Funds
o Capital Project Funds
o Debt Service Funds
o Permanent Funds
-14-
● Proprietary Funds including:
o Enterprise Funds
o Internal Services Funds
● Fiduciary Funds including:
o Agency Funds
o Trust Funds
As shown above, a Special Revenue Fund is a Governmental Fund that is generally used to account for and report the proceeds of specific revenue sources that are restricted or committed to expenditures for specified purposes other than debt service or capital projects. An Enterprise Fund is a Proprietary Fund that is used to account for business-type activities where the government provides goods or services to private parties. Special Revenue Funds and Enterprise Funds have specific reporting requirements established by the Governmental Accounting Standards Board ("GASB"), which are summarized in Table 6 below:

When establishing the financial reporting procedures for a stormwater fund, it is important to examine the activities that meet the criteria for using a particular fund. For example, a Governmental Fund, such as a Special Revenue Fund, generally has activities which are funded through taxes, intergovernmental revenues and other non-exchange revenues. An Enterprise Fund generally has business-type activities which are funded in whole or in part by fees charged to external parties for exchange transactions involving goods or services. While the fund descriptions may allow for some interpretation, GASB Statement No. 34 suggests the use of an Enterprise Fund when one of the following criteria is met: ● An activity is financed with debt that is secured solely by a pledge of revenues from fees and
charges of the activity;
● Laws require that the activity's costs of providing service, including capital costs or depreciation, must be recovered by fees and charges rather than general taxes; or
● The pricing policy of the activity is designed to recover all costs including debt-financed and internally generated capital costs and/or depreciation.
It is our understanding that the County currently accounts for certain stormwater revenues and capital costs as a Special Revenue fund while certain operating and maintenance expenses are accounted for in Public Works funds. Based on the long-term goals and objectives identified for the Stormwater Management Program, the County's stormwater activities can be accounted for within either a Special Revenue Fund or an Enterprise Fund. Either approach provides for the allocation of direct and indirect system costs to the stormwater management function and establishes an accountable framework to evaluate the sufficiency of current and future stormwater assessments over time. To the extent that the County decides to establish a separate and dedicated workforce for the Stormwater Management Program or issue debt with its repayment pledged solely from Stormwater Fees to support the Stormwater Management Program in the future, the County may want to consider establishing an Enterprise Fund to account for stormwater revenues and costs. 1.5 Existing Stormwater Organizational Structure Review
1.5.1 Review of Organizational Charts
The County provided a comprehensive Public Works Department Organizational Chart, a 16-page document that identifies a total of 670 Public Works Staff, dated March 29, 2018 (Appendix A). Based on a review of this organizational chart and conversation with County, the Project Team created a list of seventeen (17) divisions or agency staff to interview.
1.5.2 Public Works Division and Section Staff Interviews
In person interviews were conducted with Divisions or Section staff within the Public Works Department. As mentioned in Section 1.5.1, through review of the organizational chart in Appendix A and discussions with the County staff, the Project Team created a list of seventeen (17) division or sections to interview. These seventeen (17) sections were identified as having varying level of responsibility and involvement regarding stormwater related activities. The
-16-
interviews were scheduled through Division Directors or Section Managers, and often included key staff.
The interviews and responses better defined each Division's responsibilities and involvement regarding the Stormwater Management Program, approximately how many full-time equivalents (FTEs) are in each Division, what percent of Staff's time is spent on stormwater-related activities, and whether there is any tracking of stormwater-related services (software, products, etc.). Additional questions were posed associated with the direction each agency is heading regarding the provision of stormwater services, and if the current challenges or obstacles to achieving the programs goals. The interview process with Public Works Department Divisions or Sections is summarized in Table 7 below.

Some common themes or findings from the interviews include:
● With the exception of the Stormwater Services Section, it is difficult to track time spent on stormwater related activities, even through MaintStar;
● The Field Operations and Maintenance Service Units all have challenges with achieving a regular and routine maintenance schedule. The sources of this challenge include, but are not limited to, availability of staffing resources (vacancies), aging infrastructure, volume of special service requests, and increasing number of assets (growth).
● The organizational structure of the divisions and service sections across public works leads to communication and collaboration challenges throughout the planning, design, and construction of stormwater capital improvement projects. For example, the Stormwater Services Environmental Group is separated from the rest of Stormwater Services, while the Stormwater Design Project Managers are in a completely different Section. The collaboration and communication amongst the Sections throughout the project phases (planning, design, and construction) needs to be improved.
● Dedicated stormwater staff responsible for field operations and maintenance, geospatial services, and other support activities may be necessary or desirable.
● Improved tracking of stormwater activities will better support a Stormwater Fee that will fully recover the costs of both the Stormwater Capital Improvement Program as well as the Stormwater Field Operations and Maintenance and support activities.
In addition to identifying current stormwater costs, the feedback from these interviews provided valuable information to develop recommendations for establishing the proposed future stormwater program.
1.5.3 Stormwater Consolidated Organizational Chart
Based on the discussion with each Division listed in Table 7, a consolidated, stormwater focused, Public Works Organizational chart was created. This organizational chart is for internal use and intended to assist with determining which divisions or sections of Public Works staff and how many employees are involved with Stormwater System related activities. The stormwater organizational chart is a useful tool when allocating stormwater activity costs of service and is also a useful tool for designing the future Stormwater Management Program organization, activities and functions, as well as the associated costs.
The Proposed Stormwater Organizational Chart is set forth in Appendix B. The organizational chart provides a box for the director and or manager for each division or service unit. Tied to each director or manager is a circle with a number that represents the stormwater related staff associated with that division or service unit. The first chart shows the total number of stormwater related staff.
The estimated number of staff that performs stormwater related activities is approximately 405 (Appendix A). The estimated Full Time Equivalent (FTE) directly involved in stormwater activities, which is based on the estimated percent of time the 405 employees spend on stormwater related activity, is estimated to be approximately 164 (Appendix B).

1.6 Existing Cost of Service (Capital, Operations and Maintenance, Engineering and
Investigations)
The initial cost of service approach required extracting information from multiple data sources. Careful consideration was given as to not double count or miss any expenditures. The estimated cost of service considers costs associated with all seventeen (17) agencies previously identified. Examples of original sources to derive costs include interviews with Division directors and key staff, payroll data, tracking software (PTrack and MaintStar), Adopted Capital Improvement Program, Adopted Fiscal Year 2019 Operating Budget and Divisional breakdown. The exercise performed by the Project Team was further validated with the County Capital Business Intelligence section, where data was extracted from Department Budgets, Incumbent Report, and Cost Center analysis. The Stormwater cost of service breakdown was aggregated from four separate sources, which are also expanded upon in the following sub-sections:
● Stormwater Engineering and Investigations
● Stormwater Field Operations and Maintenance
● Stormwater Capital Improvement Program
1.6.1 Stormwater Engineering and Investigations
Initial discussion with County staff identified that there are many divisions and service sections that provide stormwater related support. These divisions include dedicated staff to support stormwater related activities in the areas of watershed planning, geospatial services, administration, project management, regulatory compliance, fiscal services, procurement, contract services, and business management. Through interviews with each director or manager, an estimated number of stormwater related staff, and percent of time spent on stormwater related activities were provided in order to establish an FTE for each division or service unit, which is illustrated in Section 1.4.3. The hourly salary breakdown for Public Works staff was referenced and weighted for each section, and an overhead burden rate was applied to estimate an average annual cost of service.
Through discussion with division manager, contractual services include activities services for MS4 Permit compliance. These contracts include an interlocal agreement with the Environmental Protection Commission (EPC) for chemical Analysis of Water Quality Samples for TMDL and NPDES reporting requirements. The University of Florida LAKEWATCH monitoring program. The University of South Florida aquatic system assessment and reporting, which includes Stream Habitat Assessment (HA), Rapid Periphyton Survey (RPS), Linear Vegetation Survey (LVS) and Stream Condition Index (SCI) for up to thirteen (13) streams. Finally, there is a website contract for the management of HCH2O.org). Other Contracts included USGS and Hazard Mitigation and Floodplain Management Compliance Support. Note that the NPDES activities for street sweeping are accounted for in the Transportation Maintenance Cost Breakdown.
-19-
The stormwater engineering and investigations cost of service were based on a combination of division budgets, incumbent report, and cost center analysis to an estimated value of $4,802,452.
1.6.2 Stormwater Field Operations and Maintenance Costs
The original Stormwater Field Operations & Maintenance Costs estimation approach were estimated from two primary sources: 1) Costing information extracted from MaintStar tracking system; and 2) Interviews with Division Director and Service Units. The information from MaintStar was compared against the estimates collected from the incumbent report and Transportation Maintenance Division annual budget, and there was a noticeable discrepancy in the estimated annual expenditures. Through discussions with TMD, business and intelligences, and other Public Works leadership, it was determined that, although MaintStar system, although a reliable system for tracking and logging work orders and maintenance activity, it is not currently as accurate for tracking division and departmental costs. For these reasons, the Stormwater Operations and Maintenance Costs were based on the division budgets, incumbent report, and cost center analysis to an estimated value of value of $15,977,542.
1.6.3 Stormwater Capital Improvement Program
As described earlier in this report, the Capital Improvement Program funds Watershed Master Plan Updates, the design of stormwater improvement projects identified in these plans, and ultimately the construction of these improvement projects. The program has also made a priority Culvert Renewal and Replacement Program (CRRP), Neighborhood Drainage Improvements, and the Stormwater Pumping Station Renewal and Replacement program. Also included in the CIP budget are Stormwater Pumping Station Renewal and Replacement, Water Quality and Environmental Projects, and Watershed Master Plan Updates. The Countywide Culvert Renewal and Replacement Program replaces or repairs culverts at various locations throughout Hillsborough County. The Watershed Master Plan Implementation Program studies the water quantity, and water quality if applicable in various watersheds within Hillsborough County. The Neighborhood Drainage Improvements Program is intended to alleviate flooding on County-maintained roadways that do not meet the County's level of service for flood protection. The total estimated Stormwater CIP for Fiscal Year 2019 is $22,610,000, as summarized in Table 8 below.

1.6.4 Summary of Stormwater Related Costs
Totaling the three stormwater cost components provides a complete estimate of the Stormwater Management Program's cost of service. The total estimated current annual Stormwater Management Program Costs are $43,389,994 and the cost summary breakdown is provided in Table 9 below.
Table 9 Total Estimated Annual Stormwater Management Program Costs Summary for Fiscal Year 2019
Expenditure Functions Total Costs
Stormwater Engineering and Investigations $4,802,452 Stormwater Field Operations and Maintenance $15,977,542 Stormwater Capital Improvement Program $22,610,000 Total $43,389,994
This total is beneficial in understanding the County current and future Stormwater Management Program revenue needs in order to be self-sufficient, which is essential when determining the proposed stormwater billing rate.
-21-
SECTION 2 ENHANCED LEVEL OF SERVICE – SUSTAINABLE FUNDING PLAN ANALYSIS The proposed enhancements to stormwater program activities were developed for both stormwater operations and maintenance as well as stormwater capital improvement program. Over time the County has experienced increased demand for stormwater maintenance and flood reduction activities. This has been spurred by the need to mitigate pre-regulatory development, repair or replace aging infrastructure, and growing stormwater inventory due to the rate of current development. In addition, there has been an established need to increase frequency of maintenance to become more proactive in infrastructure maintenance, especially in flood-prone priority areas. To address these concerns, the sustainable funding plan looks at enhancements to Operations & Maintenance, Asset Preservation, Flood Protection and Water Quality Projects, and Hazard Mitigation Activities. As a result of this analysis, the total sustainable Stormwater Management Program funding requirements are estimated at $81.7 million, increased from the current program cost of $43.4 million. To achieve the goal of making the Stormwater Management Program self-supporting, there is also the goal of eliminating the need for revenue from the general fund, which is proposed to be phased-in by Year Three of the sustainable funding plan implementation. The estimated number of FTEs required to achieve the sustainable funding rate is an increase of 23 FTEs, as most of the cost of the increased O&M activities in the near-term are anticipated to be provided through contractual services. 2.1. Stormwater Operations and Maintenance Enhancements
Proper and routine maintenance of stormwater assets is just as essential as incorporating new stormwater capital. Appropriate operation and maintenance activities ensure that the stormwater infrastructure will continue to function properly and yield expected design performance. Whether the stormwater asset is for conveyance and/or water quality, it is an important to provide regular inspection and maintenance in order to protect public safety, the environment, and the Counties financial investment. The following section provides recommendations regarding enhancements to Stormwater Maintenance Level of Services based on discussions with the maintenance unit divisions as well as review of the County's reported activities. Additional descriptions and details of each stormwater asset type and the associated maintenance activities are included in Appendix C. In addition, to further support the need for future enhancements to operations and maintenance activities, photographs from County Maintenance Work Orders providing examples of County Stormwater Asset and their conditions are included in Appendix C. Photographs are provided of both well maintained and functioning assets and failed or non-functioning assets. 2.1.1 Existing Stormwater Maintenance Level of Service
To properly assess expense increases resulting from stormwater maintenance level of service enhancements, an understanding of the existing stormwater maintenance level of service costs is required. As previously discussed, the County has an estimated annual budget for personnel and operating expenses regarding stormwater related activities under the Transportation Maintenance
-22-
Division. The budget estimate does not explicitly track and quantify expenses from specific stormwater maintenance activities, which is necessary when determining cost implications due to enhancements in maintenance level of service. In addition, the MaintStar maintenance and work order tracking does a good job of tracking work orders, but the data, as it is currently recorded, requires further processing to obtain useable information for budgeting and forecasting purposes. To perform these estimates for estimating future revenue requirements based on recommended enhancements, information from the three separate sources were brought together: ● Annual NPDES MS4 Permit Report; ● MaintStar Stormwater Work Orders FY 2016-2017; ● Stormwater Operation and Maintenance Annual Expense.
The NPDES MS4 permit report includes reporting quantities for annual stormwater maintenance by asset type. These reported values include asset type, quantity of asset, and current percent maintained, and is included in this report in Table 10. These maintenance frequencies were applied to unit costs specific to each stormwater asset. These unit costs were derived from MaintStar, where the FY 2016-2017 Work Orders were aggregated by stormwater asset type consistent with the NPDES reporting. This exercise included costs for labor, equipment, and materials per work order type. These costs were converted to a unit cost and applied to each of the NPDES line items. The combination of assets maintained and unit prices results in a total maintenance cost, which is compared against the Stormwater Operation and Maintenance Annual Expense. Some assumptions regarding administrative, management, and other supporting costs were required to match the estimated annual expense. The existing stormwater operation and maintenance is estimated to cost approximately $16.0 million. Including Stormwater Engineering and Inspection support increase the existing expenditure for operations and maintenance to approximately $20.8 million. 2.1.2 Enhanced Stormwater Maintenance Level of Service
Enhanced Stormwater Maintenance Level of Service recommendations provide a cost of service estimate for providing standardized frequencies for each of the reported stormwater maintenance activity categories. These recommended frequencies were determined based on discussions with key County staff regarding target performance improvements. Also, a sample of what other similar communities are reporting in their NPDES were reviewed, as well as publications from State and Federal Agencies and the Professional community. The recommended frequencies range from 60 days for pump stations to once every fifteen years for pipes, inlets, and channels. The complete frequencies of Stormwater are located in Table 10. The first year of implementation will consist of increased frequencies to underdrain systems, pipes, inlets, channels, and street sweeping. This increase in activities results in an increase in annual costs of approximately $5.95 million. The increase in activities will mostly be addressed through contractual maintenance services. There will be some increased FTE requirements associated with program management, engineering support, and project controls. Also, it is estimated that four inspectors will be required in the first year to lead the increase in inspection activities. The sustainable O&M level is estimated to be achieved by Year Two, where the proposed increase in activity frequencies results in an estimated cost increase totaling $11.9 million compared with
-23-
Fiscal Year 2019 levels including recommended increases in maintenance frequencies occur in all activities except dry retention systems and alum injection systems. The total sustainable program O&M and engineering services costs is estimated to be approximately $32.7 million. In addition to the cost of increasing maintenance activities, other operating costs supporting maintenance activities were increased as well. These include administrative, management, equipment capital, and other overhead. Also, increased maintenance activities will require additional staff support. In Fiscal Year 2020, two project managers and four inspectors are required. In addition, two FTEs associated with engineering support and one with stormwater administrative activities will be required. By Fiscal Year 2021, an additional ten positions associated with project controls, engineering support, and program management are recommended. Therefore, the required additional FTEs for Stormwater O&M and Engineering is nineteen (19).

2.2. Asset Preservation
An asset life cycle consists of inspecting, maintaining, repairing, and replacement on specific frequencies. The County has dedicated renewal and replacement programs for pump stations and pipes (or culverts). The County, in conjunction with the Project Team, has conducted an assessment of the pump station equipment and pipe inventories and compared average of asset with the typical design life expectancy. The result of the assessment was that the County needs to increase the annual replacement frequency for both pump stations and culverts in order to achieve a sustainable rate to ensure that Stormwater System assets are functioning properly. Furthermore, in order to achieve the estimated sustainable rate, an additional catchup cost is required to replace existing assets already beyond their service lives to remove the backlog from both programs. The goal of these enhancements is to replace failing assets, eliminate asset renewal and replacement backlog, provide safety and property protection, and reduce annual repair costs. 2.2.1 Pump Station Renewal and Replacement
The Stormwater Pumping Station Renewal and Replacement Program Provides annual renewal and/or replacement of stormwater pump stations throughout the County. There are 40 Pump Stations, with a current annual replacement cost budgeted in the CIP of $900,000. The CIP budget for this program has incrementally increased over the past few budget cycles. After a study was performed for the County, it was identified that there is a backlog of approximately $28,175,000. This will be addressed over an over an eight-year period before returning to the sustainable replacement cost of $900,000 annually. 2.2.2 Culvert Renewal and Replacement Program
The Countywide Culvert Renewal and Replacement Program replaces or repairs culverts at various locations throughout Hillsborough County. The County has made CRRP a priority under the current the Stormwater CIP. The County has performed an analysis of the County Culvert Asset Inventory to assign replacement frequencies based on typical life cycles replacement. This analysis reviewed over 1,376 miles of pipes with various materials and life cycles. The total replacement cost for the entire pipe inventory approaches $1.5 billion, while the current estimated backlog is approaching $100 million. The primary pipe backlog categories consist of Corrugated Metal Pipe (CMP) and reinforced concrete pipe (RCP), with consideration towards type of installation (side drain, cross drain, and outside ROW). It was determined that the Required Annual Sustainable Replacement Cost is approximately $20,300,000. In addition, in order to catchup with funding for failing assets and assets beyond their service lives, an additional backlog funding rate of $4.9 million annually is estimated to be achieved by Fiscal Year 2022 for total annual funding of $25.2 million in seven years.

2.3. Flood Protection, Water Quality & Hazards Mitigation
2.3.1 Flood Protection Projects
The County Flood Protection Projects consist of neighborhood, intermediate, and regional improvement projects. These projects primarily consist of roadway drainage and culvert improvements. The County has a ten-year Flood Protection Project List containing various types of projects across the County identified and prioritized from the latest watershed management plans. This project list approaches $200 million, with the primary driver being regional projects. The sustainable funding plan proposes to ramp up the flood protection project expenditure from approximately $7 million annually to $17.0 million by Fiscal Year 2022. The neighborhood and intermediate projects will be implemented in the near-term, whereas the regional projects will be implemented more gradually. Also, State and Federal grants, such as SWFWMD Cooperative Funding Initiative (CFI) and FEMA assistance programs can be utilized as cost sharing opportunities to implement the project list. 2.3.2 Water Quality and Hazard Mitigation Program Projects
The County has two separate programs dedicated to Water Quality and Hazard Mitigation. As mentioned previously, the water quality program works with multiple agencies and academic groups to collect water quality data and conduct water quality studies to meet or comply with Total Maximum Daily Load (TMDL) regulations. The County recently launched a one-water initiative that proposed collaboration amongst various agencies and programs emphasizing regional ponds and regional offsite mitigation areas (ROMA), public-private partnership opportunities, and surface water resource assessments. In addition, the County will be establishing Green Infrastructure and Low Impact Development (LID) guidance documents and design standards, with specific focus on green infrastructure retrofit opportunities. In terms of Hazard Mitigation, the County has over 200 National Flood Insurance Program (NFIP) defined repetitive-loss properties. As part of the sustainable program, the County is planning to establish a program to acquire these properties to eliminate future flood risk, and convert the property to stormwater treatment, flood attenuation, community park amenity or ecological area. This new and enhanced program will require a recurring annual funding amount of $3.9 million. Both Water Quality and Hazard Mitigation programs will seek cost sharing opportunities that align with the programs goals and objectives, in an effort to maximize benefits to the community. To support the increased activity of the Hazard Mitigation Program, a total of two additional FTEs have been identified. 2.4. Enhanced Sustainable Funding Plan Summary
By Fiscal Year 2022, the County plans to reach the enhanced sustainable funding target of $81.7 million. The five-year sustainable plan revenue requirements for each category is summarized in Table 11. Also, a projected 10-year sustainable funding plan graphic is provided in Figure 2. The revenue requirements within each category may shift over time, based on specific flood project or other factors, but the total expenditures are expected to remain at these levels over the next 10 years. The revenue requirements will be reassessed in the future and adjusted accordingly, based
-26-
on cost inflation and Stormwater Management Program needs. Other specific details regarding future baseline and enhanced program revenue and expenditures, as well as stormwater rate requirements, will be evaluated under the Financial Forecast Section.

2.5. Basin Area ERU Analysis
As part of the Business Plan, an area-based assessment was performed to evaluate the land area, population, and ERUs within the County's major watersheds. As part of the basin analysis, the County was divided into four areas that roughly align with the following watersheds: ● West: Northwest 5 Watershed;
● North: Cypress Creek, Hillsborough River and Tampa Bypass Canal, Pemberton Creek and Baker Canal, and East Lake;
● East: Alafia River and Delaney and Archie Creek;
● South: Bullfrog Creek, Wolf Branch, and Little Manatee River
The varying statistics regarding the properties of these aggregated areas have been summarized in the Table 12 on the following page. Furthermore, the ERU Totals based on the proposed rate structure were also spatially distributed into the areas shown on Figure 3.

SECTION 3 STORMWATER RATE STRUCTURE ANALYSIS
Based on the Scope of Services, an evaluation of Stormwater Rate Structure Alternatives was conducted to identify the most appropriate rate methodology for the County. Through numerous meetings and discussions with the County, it was determined that impervious area rate method remains the most reasonable basis for the County's Stormwater Fees. Also, a tiered single-family residential rate, rather than a single ERU rate for all single-family homes is considered a more fair and equitable approach and is recommended. Under the tiered rate approach to billing single-family residential properties, these properties are categorized by the size of the residence with larger properties billed a higher rate than smaller properties. Given the wide range of household sizes within the County's stormwater service area, the tiered approach matches the estimated stormwater cost / benefit relationship better than the current one-size-fits-all approach. Condominiums, mobile homes, and apartments were also evaluated. Since non-residential billing characteristics are already based on impervious area measurement for each individual property; no additional impervious area analysis is required for the non-residential properties at this time. 3.1 Single-Family Residential Rate Structure Evaluation
3.1.1 Single-Family Tier Methodology and Equivalent Residential Unit Estimate
Through statistical analysis of the County's single-family residential building footprint dataset, it was determined that natural breaks occurred between building footprints at or below 1,500 square feet (small tier) and building footprint at or above 3,201 square feet (large tier). These natural breaks generally fit a bell curve distribution, as represented in Figure 4, on the next page. The medium tier consists of building footprints between 1,501 and 3,200 square feet and totals 159,632 residential single-family parcels, which makes up approximately seventy-two and four-tenths percent (72.4%) of the total single-family residential properties. The small tier consists of building footprints between 100 and 1,500 square feet and totals approximately thirteen and three-tenths percent (13.3%) percent of the single-family residential households. The large tier contains parcels between 3,201 and 5,700 square feet and totals thirteen and eight-tenths percent (13.8%) of the single-family residential parcels. Additionally, there is a statistically significant population of single-family residential parcels above 5,700 square feet, totaling one-half of one percent (0.5%), or 1,067 parcels. A breakdown of the proposed single-family tier categories is provided in Figure 5.

Based on a generally accepted approach described by Peter Tryfos in his text Sampling Methods for Applied Research, a proportional stratified random sample is an appropriate method for accurately estimating the single family residential average impervious area to establish the updated ERU basis. This method has been determined to be an appropriate for estimating the ERU value, since a proportional stratified random sampling technique provides a more accurate means of sampling of the entire population of parcels. Sample sizes have been provided to produce impervious area statistical means bound by a 95 percent confidence interval of the entire population of single-family residential parcels. Using this method required the following steps to be performed:
1. Select random sample of parcels was selected from each tier group.
2. Determine the total impervious area of each selected parcel in each stratum.
3. Determine the total impervious area for each stratum by computing the product of the stratum mean and the total parcels in the stratum.
4. Sum the total impervious area for all strata.
Two assumptions that were made to determine the sample stratum sizes include: 1) the variance of the impervious area for the parcels in each stratum has a strong correlation to the variance of the square footage of the main structure in the parcels in each stratum; and 2) the distribution of total impervious area for each stratum is normally distributed.
To analyze the four single-family residential tiers, sample sets were provided for impervious area collection and verification, the sample size uses the "law of large numbers" to generate a statistically significant sample size, combined with the random stratified sampling. This summary is provided in Table 13 below.

>5,700 Very Large 828 828 Total 227,445 1,055
3.1.2 Single-Family Residential Impervious Area Collection Procedure
Impervious areas for each tier were developed using a combination of manual Heads Up digitizing and area extraction of building footprints in GIS format provided by Hillsborough County. The
-32-
2016 Hillsborough County imagery was used in most cases. ESRI base map imagery was used for structures built after 2016.
The parcel map was not spatially correct in many areas. In some cases, the parcel lines did not match the aerial by as much as fifty feet (50 ft.). The impervious areas in these regions were digitized to the apparent property line based on observation of the aerial.
Hillsborough County building footprint polygons were utilized for building impervious area estimates. Each building polygon was compared to the aerial to verify spatial continuity. Buildings were manually digitized when they did not match the aerial. In low visibility areas due to overhead foliage, Google Street view was employed to better visualize obstructed impervious areas. These areas were approximated using this information together with visible elements.
3.1.3 Single-Family Residential Results
As a result of the impervious area delineation for the 1,055 proportionally stratified random samples, an average impervious area of 4,267 square feet was estimated for the residential single-family class of service as a whole. Applying this value to the results of the tier analysis of impervious area resulted in the ERU values included below in Table 14. The small residential tier has an assigned ERU of 0.55, the medium tier equals 1.00 ERUs, and the large tier category is assigned an ERU of 1.53. The very large tier parcels are to be assigned an ERU based on their actual measured impervious area, similar to non-residential parcels.
Table 14 Single-Family Residential Tiered Equivalent Residential Unit Values
Building Footprint Range Tier Parcel Count Assigned ERU
100-1,500 Small 32,697 0.55 1,501-3,200 Medium 153,402 1.00 3,201-5,700 Large 27,845 1.53
>5,700 Very Large 781 Actual The average single-family residential value of 4,267 square feet is the proposed basis for ERU measurements for the conversion rate of all other categories, such as multi-family, mobile homes, and non-residential. 3.1.4 Condominium Rate
Based on an August 16, 2018 meeting with the Project Team and County staff, it was requested that a similar impervious area analysis be performed on the condominiums as was performed on the single-family residential parcels. The County currently assesses residential condominiums at a rate of 0.5 equivalent residential units (ERUs).
From Hillsborough County's current tax roll, the Project Team extracted all residential condominium complexes (434 condominiums) in Hillsborough County in an Excel spreadsheet by
-33-
condo name, condo group code, condo code, example folio, example property identification number (PIN), and count.
The Project Team determined that the condominiums should be sorted and "grouped" by condo group code to create discrete condominium complexes. Through this sort and grouping, Applied Sciences created 202 unique condominium complexes ranging containing 2 to 43,186 units. The Project Team divided the list of condominium complexes into a "large" and "small" category and sampled 30 condominium complexes from each list for a total of 60 condominium complexes.
The median value of 82 units was the dividing criteria between the two sampling categories. Therefore, the "small" category was defined as condominium complexes with 2 to 82 units. The "large" category was defined as condominium complexes with 82 to 43,186 units. Each list was numerically stratified based on number of units and randomly sampled similar to the single-family residential analysis.
Once the Project Team randomly selected 60 condominium complexes, these properties were analyzed for impervious area similar to the single-family residential impervious analysis. During the random sampling process, we encountered certain developments with commercial developments and manufactured homes – in these instances, the nearest condominium complex in the stratified list was selected for analysis.
3.1.5 Condominium Results
Table 15 provides several statistics for the "small" and "large" categories based on the results of the sampled data. Statistics based on the combined data set (small and large categories combined) were also included in Table 15. In general, we found the standard deviation to be relatively large around the respective sample set averages.
Table 15 Statistical Analysis of Condominium Complex Sample Sets
Sampling Statistic Small Category Large Category Combined
Count (Condominium Complexes) 30 30 60 Average Impervious (square feet, sf) 96,154 341,058 218,606 Average Units (per condo complex) 35 200 118 Average Impervious/Units (sf /Units) 2,566 1,495 2,289 Standard Deviation (sf/Units) 1,513 742 1,315 Standard Deviation as a Percent of
Average Impervious/Units 59% 50% 57%
The combined average of 2,289 square feet per, unit as compared to the recommended ERU basis of 4,267 square feet, supports the County's current billing rate of 0.5 ERU on an overall customer class basis. However, the standard deviation demonstrates that the ERU values for each parcel vary within this service classification. To demonstrate this, the results of the small and large categories were plotted to try and derive any correlation in the data. As shown in Figure 6, no discernable correlation is recognized.
-34-
3.1.6 Apartments Rate Structure Assessment
Based on the September 21, 2018 meeting with the County, it was requested that a similar exercise as the Condominium assessment be performed on the Apartment parcel classes. There are 314 Apartments classified as multi-family residential (MFR) Class A through E. 180 are defined as MFR A through C, and 134 are Classified MFR D and E.
As previously performed, a stratified random sample of 30 parcels were selected for each category, and the impervious areas were estimated.
3.1.7 Apartment Results
Table 16 provides several statistics for the two categories based on the results of the sampled data. We also provided statistics in Table 1 of the combined data set (small and large categories combined). In general, we found the standard deviation to be relatively large around the respective sample set averages.
Both separated and combined, the measured average square footage suggests, on the basis of 4,267 square feet, an ERU of 0.33 for apartments. The standard deviation of MFR A-C is only twenty

percent (20%) of the average, and the Scatter Plot on Figure 7 supports a relative correlation. Category MFR D-E has a higher standard deviation, and a less noticeable correlation.

3.2 Rate Structure Analysis
Based on the County's Fiscal Year 2018 Stormwater Assessment billing statistics, the Project Team has developed an evaluation of rate structure alternatives, including updating the ERU definition from 1,800 sq. feet to 4,267 sq. feet and implementing a four-tiered residential rate structure as discussed previously in this report. Below is a summary of the County's Fiscal Year 2018 Stormwater Assessment billing statistics and revenues assuming a rate of $42 per ERU:

Total 292,365 557,152
In the rate alternatives that are evaluated herein, based on discussions with County staff, we have assumed that the County will continue to bill all multi-family and mobile home customers based on 0.5 ERUs per unit and the agricultural customers based on 1.0 ERU per unit; therefore, the analysis shown in the rate alternative summarized below demonstrates the rate impact of changing the ERU standard from 1,800 sq. ft to 4,267 sq. ft. and implementing a TIERed single-family residential rate based on the size of the home.

SECTION 4 FINANCIAL FORECAST TO SUPPORT STORMWATER MANAGEMENT PROGRAM A major component of the Stormwater Management Program's utility rate study and strategic plan is the development of a financial forecast to support the Stormwater Management Program's goals and objectives. The financial forecast task includes development of a five-year financial forecast based on the projected operations and maintenance levels currently provided by the County and the adopted "baseline" capital improvements plan. The funding needs associated with the enhanced operations and maintenance and capital costs associated with the sustainable stormwater plan are also included in the five-year financial forecast to estimate the total revenue requirements associated with the Stormwater Management Program Sustainability Plan. 4.1 Five-Year Financial Forecast
The County's Stormwater Management Program is currently funded from a non-ad valorem special assessment and from general fund tax revenues and other non-recurring minor sources used to fund certain functions that provide stormwater services. In preparing the five-year financial forecast, a major objective is to identify the total Stormwater Management Program revenue requirements to estimate the Stormwater Fee levels that would be required to fully fund the Stormwater Management Program costs on a sustainable basis, whereby the rates for service fully fund the operation, maintenance, repair, facilities construction, renewal and replacement of stormwater assets, and administration of the Stormwater System. The various expenditures associated with operating and maintaining a stormwater utility system, as well as the cost of financing capital improvements, are generally referred to as the utility revenue requirements. The sum of these cost components represents the rate revenue requirements. The revenue requirements for this financial forecast are predicated on an analysis of the "Forecast Period" stormwater costs for the five fiscal year period ending September 30, 2024. The projected revenue requirements included the various general cost components described below: ● Operating Expenses: These expenses include the cost of labor, materials, supplies, utilities,
and other items necessary for the operation and maintenance of the stormwater system.
● Debt Service: Debt service includes the principal and interest on current and future obligations payable from the net operating revenues of the stormwater system. The County does not have any currently outstanding debt and does not anticipate issuing any debt during the Forecast Period.
● Other Revenue Requirements: This component of cost includes, in general, any ongoing capital improvements (capital outlay) to be funded from revenues for ongoing stormwater system renewals and replacements.
(Remainder of page intentionally left blank)
-41-
In conjunction with County staff, the Project Team has developed an estimate of stormwater water operations and maintenance costs based on an allocation of the adopted Fiscal Year 2019 budget for the following Public Works funds: ● Fund 10300 – Transportation Trust Fund
● Fund 00004 – Countywide General Fund
● Fund 00051 – Unincorporated General Fund
● Fund 10219 – Stormwater Utility Assessment Fund
The estimated cost of the Stormwater Management Program was generally based on the allocated number of full-time employees (FTEs) and related operating expenses involved in stormwater operations and maintenance activities. A summary of the estimated stormwater operating and maintenance costs based on an allocation of the Fiscal Year 2019 Public Works operating budget was developed in conjunction with the County staff as summarized below and shown in detail on Table 21. 4.2 Assumptions and Considerations
The projected revenue requirements for the Forecast Period are shown in Table 25 for the Stormwater System. The projected revenue requirements include the baseline operating and capital costs and the additional costs associated with the enhanced operations and maintenance activities and sustainable capital funding plan. The projected baseline revenue requirements associated with current operations reflect certain assumptions, considerations and analyses as follows: 1. As shown in Table 21, the proposed Fiscal Year 2019 operating budget associated with
Stormwater System activities serves as the basis for the operating expenditure projections for the Forecast Period shown on Table 22. The Fiscal Year 2019 Public Works budget was allocated between the Public Works and stormwater functions by County staff based on an analysis of staff activity levels. Unless otherwise noted, the underlying assumptions and expenditure amounts included therein are assumed to be reasonable and reflect projected stormwater operating and maintenance costs.
2. The baseline operations and maintenance expenses associated with current operations of the Stormwater System for Fiscal Year 2019 are projected for the remaining five (5) years of the Forecast Period (i.e., Fiscal Year 2020 through Fiscal Year 2024) as illustrated in Table 22. The following summarizes the general cost escalation factors used to project future expenses:
a. Labor-Related Increases = 3.0% Annually
b. Health Insurance = 10.0% Annually
c. Property and General Liability Insurance = 5.0% Annually
d. Fuel Costs = 5.0% Annually
-42-
e. Utilities Costs = 3.25% Annually
f. Repairs and Maintenance Expenses = 4.0% Annually
g. Professional Services = 3.0% Annually
h. All Other Costs Based on Projected Inflation of 2.5% per Year on Average
3. The projected operations and maintenance expenses also in the cost of increasing maintenance activities to enhance the level of stormwater service provides as identified in Section 2. In order to phase-in implementation of the Stormwater Program Sustainability Plan, the projections assume additional expenditures of $5.9 million in Fiscal Year 2020 increasing to approximately $11.9 in Fiscal Year 2021. Beyond Fiscal Year 2021, the projections assumed a three percent (3%) annual increase in the cost of operating and maintenance enhancements.
4. The capital expenditures for Stormwater System are based on estimated project costs included in the County's "baseline" Capital Improvement Program ("CIP"). Table 23 provides a detailed listing of the planned stormwater capital projects for the five-year Forecast Period. In general, the major expenditures in the CIP include the following type of projects:
a. Canal Dredging
b. Culvert Renewal and Replacement Program
c. Neighborhood Drainage Improvements
d. Stormwater Pumping Station Renewals and Replacements
e. Water Quality Improvements
f. Watershed Drainage Improvements
g. Watershed Master Plan Updates
5. The projected ERUs and revenues under the proposed stormwater rates by customer classification are set forth on Table 24. The projected ERUs are based on an average growth over the forecast period of approximately 1.7% annually. This growth rate is consistent with growth rates assumed in recent water utility system projections. The projected revenues on Table 24 show revenues that are anticipated based on the phase-in of the proposed maximum annual assessment over a three-year period.

As shown on Table 25, which summarizes the Stormwater Management Program cashflow, after adjusting for early payment discounts and tax collector fee, the amount of stormwater revenue received indicates that General Fund contribution to the Stormwater Management Program costs decline from an estimate of $17.4 million to approximately 1.6 million in Fiscal Year 2022. This decline reflects the phase-in of stormwater rate increases from Fiscal Year 2020 through Fiscal Year 2022. The cashflow projections are also shown on Table 25 and are also subject to assumptions regarding system growth and operating cost inflation. A summary of the five- (5) year projections showing the projected deficiency (i.e., required General Fund contributions) is summarized in Figure 9 below:

SECTION 5 FINDINGS AND CONCLUSIONS Based on our investigations and analyses in developing the Stormwater System Business Plan and Rate Study, we offer the following findings and conclusions: 1. The County should consider updating its Stormwater Fee rate structure to incorporate the
revised Equivalent Residential Unit value and Residential TIERed rates.
2. The County should consider establishing a Stormwater Fee phase-in based on full cost recovery of the County's Stormwater Program Sustainability Plan including enhanced levels of maintenance activities and capital reinvestment in aging infrastructure.
3. The County should consider designating certain staff to the Stormwater System functions to be able to more accurately identify the cost of Stormwater System operations and maintenance.
4. The County should maintain its current Special Revenue Fund designation until such time that it implements specific stormwater staffing designation and cost accounting, which at that time the County may wish to establish a Stormwater Enterprise Fund.
5. The County should consider implementing a Stormwater Mitigation Credit Program over the next several years.
6. The County should maintain its current Non-Ad Valorem Special Assessment billing method, recognizing that certain future basin-specific capital investments may require a basin-specific capital charge rather than a County-wide rate to satisfy the special benefit rules of the Florida statutes related to the Special Assessments billing method.

STORMWATER SYSTEM MAINTENANCE PHOTOGRAPHS
Type Image Description Maintenance Activities
Dry Retention Systems
Constructed or natural depressional areas, where the bottom is typically flat, and natural ground cover or other appropriate vegetation is used to promote infiltration and treatment of stormwater runoff.
Maintain healthy vegetative cover to prevent erosion and nutrient uptake. Mow as needed. Remove accumulated sediment, trash, and debris from facility bottom and inflow/outflow structures.Repairs and replacement to damaged or aging piping and control structures. Restore infiltration capacity by scraping/aerating basin bottom
Underdrain Filter Systems
Stormwater Piping installed with the purpose of collecting stormwater runoff and allowing it to infiltrate into the surrounding soil and down to the groundwater table.
Inspection for clogging, vacuum or jet cleaning.
Wet Detention Systems
Designed to be permanently wet, which allows material to settle and be absorbed. After a storm, water leaves the pond through a pipe in the "control" structure. Part of the pond — known as the permanent pool — is always below the level of the drain structure. Sometimes aquatic vegetation is planted around the pond’s perimeter to help filter sediment in stormwater runoff.
Mowing (berm and embankments). Vegetation Management. Trash and debris removal. Control Structure inspection, cleaning, and repair/replacement.
Alum Injection Systems
Alum treatment is applied to enhance pollutant removal efficiencies in traditional stormwater treatment system. Components for alum stormwater treatment system often include chemical metering pumps, storm sewer flow meters, electronic controls, and an alum storage tank. These are typically housed in a central facility. Alum feed lines and electrical conduits are run from the central facility to each point of alum addition and flow measurement.
Maintain chemical levels. Routine mechanical and electrical equipment inspection and maintenance. Floc management and disposal.
C-1
Type Image Description Maintenance Activities
Pollution Control Boxes
Boxes/Structures placed at outfalls or strategic locations within stormwater system to separate/trap trash, debris, sediment, and other pollutants from stormwater runoff. Examples include CDS, Baffle Box, Stormceptor, and Vault.
Inspection, cleaning, repair, and/or replacement. Has a tendency to require higher frequency of inspection and cleanout than typical inlets and catch basins, since it is designed to collect and trap trash, debris, sediment, and other pollutants.
Pump Stations
Stormwater conveyance when gravity drainage is not practical or feasible. Includes wet well, pumps, controls, drivers, and housing. Primary purpose is for flood protection.
Typical pump station O&M activities. Preventative Maintenance practices spec'd with each pump, including operational checkups. Note abnormal vibration and correct problems. Check motors and rotating elements for high temperatures. Inspect pumps and motors for coating failure, oxidation, and reapply coating. Fix leaking, corrosion, lubrication, and misalignment. Check for unusual grit and check if operating near shutoff head.
Major Outfalls
Outfalls are point discharge into major waterbodies and associated branches. These locations are critical for conveying stormwater away from County stormwater collection system and into the
inspect for clogging and obstructions, cleaning, repair, and/or replacement.
Weirs or Other Control Structures
Weirs and Control Structures regulate the release of stormwater. These are use to vary the rate of discharge downstream, meet peak flow demands, and provide attenuation for water quality treatment, and
inspect for clogging and obstructions, cleaning, repair, and/or replacement.
Pipes and Culverts (miles)One of two primary methods for stormwater conveyance. Utilized in developed areas or locations where there are open channel crossings.
TV Inspections, Clean, repair, and replacement. Pipe and Culvert end treatment repair and/or replacement.
C-2
Type Image Description Maintenance Activities
Inlets and Catch Basins
A catch basin (a.k.a., storm drain inlet, curb inlet) is an inlet to the storm drain system that typically includes a grate or curb inlet where stormwater enters the catch basin. Includes some control structures.
Inspection, cleaning, repair, and/or replacement
Channel, Ditch, and Canal (miles) Other primary method of stormwater conveyance. Cleaning/scraping, mowing, and spraying
Street Sweeping
Street sweeping is performed to keep streets and stormwater systems clean, reduce flooding and enhance water quality. Street sweeping prevents trash, sediment, and other pollutants from entering the stormwater system and downstream waterbodies.
Contracted Out. 4 types of sweeping, routine arterials, demand sweeping, local sweeping, and sweeping for study of TMDLs in the East Lake area.Routine Arterials – approximately 663 lane miles monthly.Demand Sweeping – citizen call ins requesting sweeping services.Local Sweeping – consists of approximately 4500 lane miles swept once per year.
Wetland Mitigation
Areas where wetland enhancement, restoration, creation and/or preservation project serve to offset unavoidable wetland impacts. The ecological benefits of a mitigation project should compensate for the functional loss resulting from the permitted wetland impact.
Vegetation control (spray, scrape, trimming, burning); Topsoiling and seedbed preparation;planting and mulching;water level reporting and control;

Fundamentals for Stormwater Mitigation Credits
OverviewStormwater Mitigation Credits have been offered stormwater utilities in order to demonstrate that the Stormwater Management Program equitably and fairly recognizes the mitigating benefits provided by certain properties and to encourage proactive stormwater investments and activities. Of particular interest is the encouragement of stormwater activities that support reductions of nutrients and improvement of water quality. The following is a discussion of basic stormwater credit programs offered by stormwater utilities in Florida. It is important to note that while some kind of credit program may be warranted based on the results of various court cases in Florida, the exact nature of such programs is not proscribed. If a Stormwater Mitigation Credit is going to be offered the County must define a program that is fair and equitable to the properties served by the Stormwater System based on the current and potential future enhancement of the stormwater benefits provided by the County.
In general, a credit is offered to customers of a service charge for two basic reasons:
to recognize properties that reduce their need for County stormwater service due to onsitereductions in stormwater discharge; and,
to encourage good stormwater management behavior (e.g., provide for the treatment ofstormwater runoff).
In either case, the mitigation credit reduces the Stormwater Fee applicable to the property and should be based on reductions in certain stormwater services provided by the County. Four fundamental tenets of credit policy must be considered in the development of stormwater mitigation credits.
Program/CreditConsistency. The first is that the credit program can only be as robust as the stormwater management program offered by the County; that is, the stormwater management ordinance and associated design manual must be coordinated with the credits offered. For example, a credit program should not offer reductions for green infrastructure (best management practices that mimic more natural runoff patterns) if the available stormwater design manual does not address such practices.
ProofofCreditEligibility. The second is related to the assurances that the credit activity is being completed on the parcel potentially receiving the credit. For example, if the credit is for a stormwater mitigation pond, then the pond must be properly designed, constructed and maintained to assure that the benefits of the pond are accomplished. If the pond is not designed properly, poorly constructed, or infrequently maintained, the pond will not provide stormwater improvements for which the credit is given. Therefore, whatever the credit is, proof must be demonstrated and documented by the applicant and confirmed by the County that the property is eligible.
BalanceofCostsandBenefitsofCreditandAdministration. The credit program must be balanced with the costs required to administer the program. A complicated credit program that requires significant administrative efforts to receive the application, confirm the applicability, modify the bill and to inspect the property can be expensive. This expense must be balanced with the benefit offered by the credit to the property owner and the associated benefit to the Stormwater System.
MaximumCredit. Finally, the maximum credit offered needs to be related to the service reduced by the credit recipient. That is, if the customer still receives stormwater service from the County but has reduced runoff from their site by some means, the maximum credit should not be 100 percent. Service is still being provided in this instance. The decision on the maximum credit should therefore be based rationally on the reduction in level of service provided.
Summary of Mitigation Credit Policy Options Provided below is a review of credit policy options provided by other Stormwater utilities. For the purposes of this review, an onsite mitigation facility or activity will be referred to as a stormwater control measure, or SCM.
Maximum Credit
As noted previously, the maximum credit should be related to the reduction in stormwater services required by the property. Stormwater services are categorized as Program Management (services to manage the program), National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Permit Compliance, activities required to comply with the MS4 permit, excluding O&M), Operation and Maintenance (O&M), and Capital Improvements (CIP).
In general terms, services in both the Program Management and MS4 compliance areas are provided to all customers in the County, regardless of individual activities (such as onsite SCMs) that are completed on a customer’s property. For example, for a parcel that does not discharge stormwater directly into a public stormwater system, development review and code enforcement services make sure that the development next to the parcel does not cause flooding. Therefore, a rational method to define the maximum credit is to limit credits to the percentage of the program costs that are most affected by connection to the public stormwater system e.g., operations and maintenance expenses (O&M)and capital improvements(CIP).

Pros Cons
Logical rationale for maximum credit Credit related to services reduced or not needed Simple to calculate maximum value
Precise percentages vary from year to year
Duration of Credit
Since the County’s Stormwater Fees are billed on an annual basis using the non-ad valorem special assessment method, once a credit has been approved, does the credit applies to a single annual service charge. The question is: “should the credit apply to successive service charges?” Another way to ask this is: “how often do you need to confirm that the basis for the credit still

works as designed?” This is an issue because on-site stormwater management facilities that are not maintained do not function as designed. On the other hand, excessive inspection of each on-site facility can be administratively overwhelming and costly. Some Stormwater System’s require the credit applicant to reapply once a year and some require reapplication after multiple year periods to reduce administrative costs. In some instances where private SCM maintenance is part of the properties NPDES permit, compliance with other permits (such as from the water management districts) may be sufficient assurance for the continued application of the credit. Two options are discussed below related to annual reapplication versus multi-year reapplication.
AnnualReapplicationPros Cons
Confirms applicability of credit each year Encourages proper maintenance for private
stormwater facilities Inspection of facilities can be used for NPDES
MS4 compliance
Requires higher administrative costs and efforts Requires more effort by credit recipient
Multi‐yearReapplicationPros Cons
Confirms applicability of credit after a number ofyears
Encourages maintenance of private stormwaterfacilities
Inspection of facilities may be used for NPDESMS4 compliance
Reduced administrative costs Reduced costs for credit recipient
Does not encourage annual maintenance Some facilities may not be working for the
duration of the credit
Credit for Achieving or Exceeding Code
The issue with this policy option is whether a credit is offered to customers who have onsite stormwater SCMs that meet current code or to only those who provide stormwater SCMs that exceed current code. In the first case (on-site facilities that meet code), the justification is that the parcel with the SCM results in a lower runoff rate, volume and/or pollutant loading compared to a parcel with no stormwater SCMs. So, for this option, all properties with SCMs that meet current code can receive a credit.
For the second case (on-site facilities that exceed code), only those facilities with SCMs that exceed current code requirements can receive a credit. New developments and significant redevelopment have been required to provide peak rate controls (i.e., attenuation) and water quality treatment since the mid-1980’s in Florida. The County’s Stormwater System has been built to accept such constrained runoff from new development since that time. That is, stormwater ditches and pipes built since the mid-1980’s have been sized to accept uncontrolled runoff from parcels developed before the mid-1980’s and SCM-controlled levels of runoff from those parcels developed after the mid-1980’s. Therefore, parcels with SCMs constructed to meet current development code do not measurably reduce the ability to manage the runoff burden to the Stormwater System.

Credits for Reduction of Runoff
Stormwater runoff can also be reduced by structural controls. Structures such as stormwater ponds (detention and retention), and raingardens, as well as numerous other green infrastructure, can reduce the rate and/or volume of runoff to the County’s stormwater system. Also, some types of water conservation, such as runoff reuse, that reuse rainfall for irrigation also reduce the runoff. Each of these methods control runoff to a varying degree and so, two options have been used for credits: a variable credit that is dependent on the volume of runoff controlled (e.g., Pinellas County) or a single credit based simply on the presence of the structure. A variable credit is more difficult to administer and requires the applicant to provide additional information (likely from a professional engineer which may deter application for the credit). Also, for this type of credit structure, it is more important for the County to confirm applicability by review of the design, construction and ongoing maintenance to ensure continued reduced runoff from year to year.
It should be noted, however, that except for types of retention facilities (i.e., facilities that control volume), most stormwater facilities do not reduce the volume of stormwater that runs off the site – they slow the runoff to a manageable pace by attenuating the peak rates and let it leave the siteat a reduced rate. Therefore, such stormwater facilities do not significantly decrease the waterquantity related services that need to be provided by the Stormwater System.

Credits for Treatment of Runoff
In 1982, the state of Florida adopted regulations that required new development to treat stormwater runoff. The rules were based on the treatment of suspended solids but in doing so also provided for the ancillary treatment of other pollutants. In 1990’s, these rules were expanded to include load reductions for pollutants that could cause or contribute to impairments. Recently, water management districts have required additional treatment when discharge is to state waters that are impaired (i.e., exceed the applicable water quality standards). Therefore, residential subdivisions and non-residential properties built after 1982 have stormwater facilities that treat runoff pollutants.
Sometimes independent of the reduction of runoff peak rates, stormwater facilities can reduce the pollutants contained in the runoff through treatment. Stormwater treatment comes in three forms: physical (settling), chemical (modification of pollutants to not-as-problematic forms) and biological (consumption of the pollutant by animals and plants). For example, a stormwater pond can slow stormwater runoff down to allow settling of particulate matter and allow the biological consumption of nutrients. Stormwater ponds can be augmented to enhance treatment by the introduction of a coagulant (e.g., alum) or by extra biological matter (e.g., floating mats or littoral shelfs).
The complication is that each method of treatment has different efficiencies of treatment of various pollutants. For example, a wet detention pond can reduce sediments by 80 to 90 percent but nutrients only by 30 to 50 percent. A retention pond, on the other hand, can reduce all pollutants by over 90 percent.

Rewards customers with stormwater treatmentfacilities
Promotes maintenance of onsite systems Reduces stormwater pollutant discharges from
new development and those built after 1982
Can be highly variable by facility type andpollutant
Credits for No Discharge to the Stormwater System
A non-discharge would be either a parcel for which the runoff flows to a state water body or the 100-year storm event is retained entirely onsite. The original argument for this was that sincethey do not “use” the stormwater management system, they should not pay a Stormwater Fee.The majority of stormwater utilities in Florida do not offer properties that do not discharge to theStormwater System a one hundred-percent credit (100%) with the reason being that even
D-5
properties that do not discharge to the stormwater system still receive some stormwater services. Increased stormwater levels induced by non-County controlled systems into receiving waters reduce the availability of such capacity used by the overall Stormwater System. Also, if these properties discharge directly to an impaired waterbody, the County is still responsible for reducing the county-wide pollutant load discharging to these waters. If a property has no discharge to the County’s system, then services such as operation and maintenance of the facilities and capital improvements for flood control may not be provided to that specific property. However, the property will still receive services related to code enforcement, development review, water quality improvement projects, and MS4 permit compliance, to name a few. Therefore, many stormwater utilities offer credits to properties that do not discharge to the stormwater management system that include only the relative proportion of costs for program management and MS4 compliance and water quality projects.
CreditsforNoDischargePros Cons
Recognizes the control of the property’s runoff Reduces localized flooding
Properties still receive some of the Countystormwater services
