Burke Engineering, LLC. City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 CHAPTER 1 PROJECT OVERVIEW & SCOPE Like many local governments in Indiana, the City of Carmel is faced with the challenge of paying for increasing stormwater regulatory requirements and ongoing stormwater infrastructure maintenance and improvements. Carmel currently pays for the stormwater program using the general fund. This means the stormwater program competes directly for funding with all of the other important and popular services provided by the City. Recognizing the benefit of providing a stable funding source to better meet current and future program demands, the City retained Christopher B. Burke Engineering, LLC (CBBEL) to develop a budget for stormwater program management and capital improvements, and to assist the City with the determination of a fair and appropriate utility user fee. 1 �1 rSTORMWATER{UTILITYAS1A+FUNDING !MECHANISM;;:;' tl1B Christopher B. Burke Engineering, LLC The stormwater utility is a proven method of providing a reliable funding source for the management of stormwater programs. This funding source is provided through a user fee similar to the fees collected for public water and wastewater services. The stormwater utility is unique (when compared with water and wastewater utilities) in that the service cannot be disconnected for nonpayment, service is provided to all citizens without choice, and the actual service to a particular property is difficult to quantify. Consequently, the successful implementation of a stormwater utility requires a good stormwater management program with well-defined deliverables as well as public support through education and outreach. This type of funding mechanism has been coined Stable, Adequate, Flexible, and Equitable (SAFE). A stormwater utility is stable because it is separated from the annual budget process and does not compete with other public services and programs such as schools, public safety, and solid waste. This stable revenue source allows stormwater managers to effectively implement their stormwater program and complete drainage projects. A stormwater utility is adequate because the user fee is calculated based on a detailed evaluation of program needs and the capital improvement plan. It is flexible because the rate structure can include any number of modifiers such as caps, economic incentives to reduce user fees, variables for land use types (vacant land, special use or tax exempt properties), and secondary funding methods to meet the stormwater management program objectives. Finally, a stormwater utility is equitable because the user fee is proportional to the volume of stormwater runoff for each parcel. 4 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 STATEaAUTHORITY;FQR`MIINICIP.ALITIES TQfcOLLECT{STORMWATERiFEEs-•-• Indiana law allows municipalities to collect user fees necessary to manage the capital improvement and operational expenses associated with stormwater management. This can be done by either creating a new Department of Stormwater Management or expanding the scope of services of the existing Municipal Sewage Works. Department of Stormwater Management (IC 8-1.5-5) IC 8-1.5-5 was established in 1988 as a specific tool for cities and town to improve their ability to manage stormwater. Under this law, municipalities must, by ordinance: 1. Establish a Department of Stormwater Management. The Department is governed by 3 member board appointed by the executive of the municipality 2. Define the district that is considered to receive a special benefit from the collection and disposal of stormwater, identify the method for determining the fee, how the stormwater funds may be used, and collection method 3. Establish the rate structure and user fee for rate payers of the stormwater utility Municipal Sewage Works (IC 36-9-23) Stormwater user fees may be collected under the 1981 statute IC 36-9-23 that authorizes municipalities to operate sewage works. While the focus of this statute is sewage, the language includes storm sewers and storm drainage as part of that system. A municipal Board of Public Works is responsible for the construction, acquisition, improvement, operation, and maintenance of sewage works. Under this option, the stormwater utility may be administered under the existing municipal Utility Board or Board of Public Works. Expanding the existing Board's responsibility requires an amendment to the ordinance that establishes their authority. RECOMMENDATION JJI It is recommended that the City seek legal counsel to determine whether to create a new Department of Stormwater Management or to expand the existing scope of services of the Municipal Sewage Works. _ IR Christopher B. Burke Engineering, LLC 5 • City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 CHAPTER 2 STORMWATER MANAGEMENT PROGRAM ilREGULATORY(MANDATEt&IPENALTIESIFOR?NIONCOM P,LIANCE As part of the 1987 amendments to the Federal Clean Water Act (CWA), the United States Congress added Chapter 402(p) to the CWA to address the water quality impacts of stormwater discharges from industrial facilities and large to medium municipal separate storm sewer systems (MS4s). Large to medium MS4s were defined as communities serving populations of 100,000 or more and are regulated by the Environmental Protection Agency (EPA) under the National Pollutant Discharge Elimination System's (NPDES) Storm Water Phase I Program. In addition to these amendments, Congress directed the EPA to issue further regulations to identify and regulate additional stormwater discharges that were considered to be contributing to national water quality impairments. On December 8, 1999, the EPA issued regulations that expanded the existing NPDES Storm Water Program to include discharges from small MS4s in "urbanized areas" serving populations of less than 100,000 and stormwater discharges from construction activities that disturb more than one acre of land. These regulations are referred to as the NPDES Phase 11 Storm Water Program. In the State of Indiana, the Indiana Department of Environmental Management (IDEM) is responsible for the development and oversight of the NPDES Phase 11 Program. The IDEM initiated adoption of the Phase 11 Rules that were ultimately codified as 327 IAC 15-13 (Rule 13). Rule 13 became effective on August 6, 2003 and requires designated MS4 entities to apply for permit coverage by submitting a Notice of Intent (NOI) and developing Storm Water Quality Management Plans (SWQMPs) through a phased submittal process. The IDEM's phased submittal requirements for the SWQMP include the following 3 components: 1. Part A: Initial Application 2. Part B: Baseline Characterization Report 3. Part C: Program Implementation Plan To deal with potential violations, EPA has 3 types of enforcement actions. These include Administrative Orders, Civil Penalties, and Criminal Prosecutions. Depending on the severity of the violation, monetary fines may range from $2,500/day/violation not to exceed as much as $157,500/day/violation. The most severe individual penalty is imprisonment for not more than 15 years and/or a fine of $250,000. Organizations, including governmental entities subject to Phase I and Phase II Programs, may be subject to fines of not more than $1,000,000. In addition to federal enforcement and penalties, Indiana may issue a civil fine not to exceed $25,000/day/violation. The City of Carmel became a designated MS4 entity in 2003. rR Christopher B. Burke Engineering, LLC 6 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 2:2ACIT( OFsCARMECdSTORMWATER{P,ROGRAM The City's plan for implementing Rule 13 requirements is contained in their SWQMP Part C: Program Implementation Report that includes a number of best management activities identified in each of the following 6 Minimum Control Measures (MCMs). MCMs #1 & #2: Public Education, Outreach, Participation, & Involvement • The City must implement and/or participate in the following activities to meet their Rule 13 requirements: • Hamilton County Phase II Public Education Steering Committee • Regional Collaboration and Partnering • Stormwater Assessments (to gauge outreach effectiveness) • Stormwater Webpage • Stormwater Educational Materials • Stormwater Messaging Packaging • Fair or Festival Booths • Clean-up Events • Household Hazardous Waste and Recycling Program Promotions (support) • "Report -A -Polluter" Program • Soil and Water Conservation District Activities (support) • Storm Drain Marking • Signage • Rule 13 Public Participation List (of those groups or individuals interested in participating) • Public Meetings and Public Notification MCM #3: Illicit Discharge Detection & Elimination (IDDE) • Defined by EPA as identifying and eliminating illicit discharges and spills from storm drain systems • The City must implement the following activities to meet their Rule 13 permit requirements: • Stormwater System Map (maintain & update) • Illicit Discharge Detection and Elimination Ordinance (update & enforce) • Illicit Discharge Detection and Elimination Plan IDDE Potential Desktop Analysis • IDDE Manual and Field Binder MCMs #4 & #5: Construction and Post -Construction Runoff Control • Defined by EPA as addressing stormwater runoff from active construction sites and after construction activities have ended BChristopher B.

RECOMMENDATION 112 It is recommended that the City create a dedicated funding source, such as a stormwater utility fee, t6 more effectively implement and meet the goals of their Rule 13 Program and to position the City to meet increasing expectations and I; _ requirements. Christopher 8. Burke Engineering, LLC 8 City of Carmel — Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 This page intentionally left blank [,Z Christopher B. Burke Engineering, LLC 9 City of Carmel — Stormwater Program & Capital Improvement Budget Study DRAFT - July 2013 CHAPTER 3 PROGRAM STAFFING NEEDS & ORGANIZATION CBBEL met with key City staff and officials and researched similar MS4 organizational structures to recommend staffing for the stormwater program. This information was used to create the "Organizational Chart for Proposed City of Carmel Stormwater Utility" provided in Appendix 1. The chart includes one additional recommended position and also the recommended percentage of salary for each staff member that should be paid with stormwater utility funds. The Organizational Chart is proposed to expand the City's existing, strong foundation that has been recognized by IDEM and other organizations as not only implementing a successful, compliant Rule 13 program but being a state leader since the program began in 2003. 3:1 )ORGANIZATIONALSTRUC'rURE� "- R Christopher B. Burke Engineering, LLC The Mayor is designated by law as the overall MS4 Operator. Rule 13 mandates that the highest ranking elected official is ultimately responsible for the development, implementation, or enforcement of the MCMs for the City. The noted Rule 13 program responsibilities have been delegated to the City Engineer who serves as the Mayor's duly authorized representative for the City. The existing Board of Public Works would also serve as the Stormwater Utility Board as described in Section 1.2. This board would make decisions about the City's overall stormwater management program, and the City Council would approve the Stormwater Utility budgets. The Stormwater Administrator is responsible for coordinating the 6 MCMs, the Assistant City Engineer provides CIP management and review, and the Staff Engineer reviews the stormwater drainage for private and residential projects. The MS4 Consultant coordinates and assists with technical services toward completing various Rule 13 activities as assigned by the City Engineer. The stormwater drainage consultant provides as needed assistance on related stormwater quantity issues. MCMs #1 & #2: Public Education, Outreach, Participation, & Involvement are coordinated by the Stormwater Administrator with support from the Stormwater Inspector as well as the Upper White River Watershed Alliance (UWRWA). The City pays annual dues to the UWRWA for their services and this line item is included in the proposed Stormwater Utility budget. In addition, help to either directly or indirectly fulfill Rule 13 program requirements is provided by other surrounding MS4 entities who each have a representative or representatives on the Public Education Committee and the City's Water and Wastewater utility; however, none of these entities would receive Stormwater Utility funds. MCM #3: IDDE tasks are coordinated by the Stormwater Administrator with support from the Stormwater Inspector. In addition, help to either directly or 10 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 I!B Christopher B. Burke Engineering, LLC indirectly fulfill Rule 13 program requirements is provided by other surrounding MS4 entities who each have a representative or representatives on the Standards, Plan Review, and Enforcement Committee, the City's Water and Wastewater utility, and the City's Household Hazardous Waste collection program; however, none of these entities would receive Stormwater Utility funds. MCMs #4 & #5: Construction and Post -Construction Runoff Control are coordinated by the Stormwater Administrator with support from the Stormwater Inspector which includes City specific day to day tasks such as permitting, review of Stormwater Pollution Prevention Plans and O&M Plans inspections, compliance, and enforcement. Tasks such as Ordinance and Technical Standards updates, training, and general procedural items are developed with the other surrounding MS4 entities who each have a representative or representatives on the Standards, Plan Review, and Enforcement Committee. The Indiana Association for Floodplain and Stormwater Management (INAFSM) Inspectors' Group is a networking forum for all MS4 entities throughout the state to learn and share stormwater program knowledge. Applicable City staff pays annual dues to INAFSM. MCM #6: Good Housekeeping & Pollution Prevention for City Operations is also led and coordinated by the Stormwater Administrator with support from the Stormwater Inspector; however, this MCM includes items such as facility management at City -owned properties and on-going maintenance of the separate storm conveyance system. Therefore, several City departments are affected by these Rule 13 requirements so the Stormwater Administrator works effectively with them to cooperatively implement the program. For example, the Street Department provides Street Sweeping and Vac Truck services which help to maintain and keep pollutants out of the separate storm sewer system conveyance. A new, proposed, full-time position, the Vac Truck Operator, is needed. Some items such as training are developed with the other surrounding MS4 entities who each have a representative or representatives on the Standards, Plan Review, and Enforcement Committee. A seasonal Stormwater Intern assists with all of the 6 MCMs as needed and directed by the Stormwater Administrator. Since the City has successfully developed a good working relationship with the other surrounding MS4 entities, Noblesville, Fishers, Westfield, Cicero, Hamilton County and Zionsville, this "partnership of the willing" has allowed each of these communities to realize resource savings, mainly labor and monetary. Additional Stormwater Quality and Quantity issues would be completed by "Private, Residential, and CIP Support" staff. A new, proposed, full-time position, the Stormwater Utility Administrator and GIS Technician be responsible for the logistics of implementing and collecting stormwater fees. 11 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 Ii :RECOMMENDATION #3 - - It is recommended: that. the City'continues to utilize the existing staff organizational Structure�to implement: their Rule 13 '. program. Further, the'City should supplement their existing stuff by hiring a new lJtilityAdrninistratorwho!should also serve as,a GIS Technician to handle(the increased workload;fot the stormwaterutilityaswell as, a:new,tVac Truck Operator to properly maintain the separate storth sewer conveyance system.

Burke Engineering, LLC 13 City of Carmel—Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 CHAPTER 4 PROGRAM COSTS Outsourced Professsional Services 10.1% To identify stormwater program costs, CBBEL reviewed the City's SWQMP Part C and Annual Reports; conducted interviews with key City staff and officials and researched costs from other similar Phase II MS4 regulated entities. General Ope ating Supplie 1.7% The budget includes a 5 -year projection that allows for the successful implementation of the 6 MCMs required by Rule 13. Appendix 2 provides a tabulation of the noted 5 -year budget and Figure 4-1 graphically illustrates the distribution of the budget categories. The costs shown in the 5 -year budget table in Appendix 2 are for the base year ("Year 1" is a representation of the first full year of implementation) and unless otherwise stated, a 3% annual inflation rate is assumed to derive costs for the subsequent years. Additional Shared Rule 13 explanations are provided below for the Compliance Coss following categories that make up the budget. 0.5% Administration/Operations The staff positions included in this category of budget items includes existing staff and the one potential new staff position. A major advantage of implementing the Stormwater Utility is that it will pay a percentage of existing City staff salaries and benefits which are currently paid out of other, stressed funds. Existing staff and the proposed percentages (based primarily on the amount of their time spent on stormwater program activities) of their salaries and benefits are the City Engineer (25%), Stormwater Administrator/MS4 Coordinator (100%), Assistant City Engineer (50%), Staff Engineer (50%), Construction Manager (50%), new GIS Tech/Utility Administrator position (80%), Construction Inspector (50%), 3 Street Sweeper Operators (75% each), new Vac Truck Operator (80%), Office Administrative Assistants (25% each), Bond Manager/Plan Review Coordinator (25%), Public Works Relations Coordinator (50%), Stormwater Inspector (100%), Seasonal Engineering Intern (50%), and Seasonal Stormwater Intern (100%). The cost for staffing the stormwater program as noted above is estimated at $810,000 for the first year. Figure 4-1 Distribution of funds within the Stormwater Budget Equipment Based on the need identified by the Engineer's Office, this category includes the one-time purchase of 2 new vehicles ($35,000 each), costs associated with the operation and/or maintenance of those and/or existing vehicles, as well as, costs associated with the operation, maintenance, and/or replacement of street sweepers and/or purchase of a vacuum truck. Costs associated with the purchase and operational expenses were gathered from similar purchases by other MS4 entities and manufacturer costs. The cost for the equipment noted ffR Christopher B. Burke Engineering, LLC 14 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 rr Christopher B. Burke Engineering, LLC above is estimated at $260,000 for the first year and is divided evenly, spread - out over the 5 -year budget. Shared Rule 13 Compliance Costs This category refers to those compliance items that are shared with and/or relied upon by other parties. This includes paying dues to the UWRWA. The estimated cost for these shared compliance items are estimated to be $12,500 for the first year. City Individual Rule 13 Compliance Costs This category included those items that the City completes and pays for independently of other parties. These costs are for local Public Education & Outreach Materials including miscellaneous booth fees, Storm Drain Marking supplies, IDDE miscellaneous supplies, GPS unit replacement and/or maintenance, Land Surveying Equipment Purchase and/or Maintenance, Compliance and Enforcement materials, separate storm sewer system maintenance, repair, and/or replacement, Permit Compliance Software, Inspection Tools and Supplies, Spill Kits and Response Monitoring Controls, as well as USGS Gage Stations for monitoring Stormwater Quantity and Quality. The separate storm sewer system maintenance line item is the largest in this category because of the vast size and amount of linear feet of separate storm conveyance, enclosed pipe, inlets, curbs, gutters, catch basins, unregulated storm drains, ditches, swales, and channels that the City owns and maintains on an on-going basis. The initial estimate of $500,000 annually is most likely not enough to cover this item so the City should conduct a detailed inventory to gain a better understanding of the actual costs needed to properly maintain and prevent wear and tear on the storm system. The total annual estimated individual compliance costs for the first year is $668,500. Training The costs in this category include items to enhance staff professional development in the stormwater management field. Items included are attending courses, classes, and/or conferences, Office of the Indiana State Chemist (DISC) required certified pesticide and/or herbicide applicator initial certifications and/or continuing education credits, as well as obtaining stormwater professional certifications and paying for renewal fees. The total cost estimate for the above noted training related items is $20,000 for the first year. General Operating Supplies This category includes administrative and miscellaneous office operating supplies. Items included are office supplies, equipment, and/or furniture; computer software and hardware operating and/or maintenance, purchases, annual upgrades, and any necessary training; as well as, oil, fuel, and/or maintenance and repair costs for existing vehicles. The first year cost estimate for these items is $45,000. 15 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 Special Projects New items that could be funded with the stormwater utility include special projects such as Capital Improvement Projects (CIP). CIP funds could be used toward smaller individual projects or collectively toward a larger, more significant project through a bond. An initial estimate of the needed funds was generated based on projects already identified in the completed watershed studies and by stormwater issues known to the City Engineer's Office. Appendix 2 includes a location map and a list of 56 known CIP projects. The City also needs to update their IDDE maps to include newly annexed areas so this would be included as a Special Project. In addition, in this budget category is Stormwater Infiltration Abatement which would allocate monies for the treatment and abatement of stormwater infiltration into the sanitary system which will help the sanitary system to work more efficiently. The initial annual budget estimate for this category is $970,000,000 for the first year, and is based on previous annual expenditures and the substantial need for continued stormwater infrastructure improvements. Appendix 2 includes a list of Project Drainage Costs from 1996 to 2013. Outsourced Professional Services With the increase in workload from the stormwater utility and funds for projects, various outsourced, professional services will be needed. Items in this category include engineering on-call services to provide technical support for program implementation, and developing an overall Stormwater Master Plan to guide the CIP and/or miscellaneous watershed studies. In addition, in the fifth year of the stormwater utility, a fee study is needed to determine if potential rate increases or decreases are needed. The total estimate for this category is $295,000 for the first year. Billing Costs CBBEL assumes that the City will utilize its existing wastewater utility billing system to generate utility bills. This fee is to maintain the stormwater billing portion of the utility bill and to reach residents on private septic. In addition, these monies would support the day to day, frontline staff who would handle the billing. The total estimate for this category is $30,000 for the first year. RECOMMENDATION #4 It is recommended that the City adopt a stormwater program budget of $ 2,900,000 to meet their Rule 13 Program requirements and implement identified Special Projects. R Christopher B. Burke Engineering, LLC 16 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 This page intentionally left blank rR Christopher B. Burke Engineering, LLC 17 City of Carmel — Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 CHAPTER 5 STORMWATER UTILITY RATE & RATE STRUCTURE �'[� Christopher B. Burke Engineering, LLC It is known that stormwater runoff carries with it pollutants as it flows over the landscape to nearby waterbodies and that pollutant loads vary depending on land use. For example, nutrients (nitrogen and phosphorus) are higher in residential land uses whereas metals (zinc, cadmium, and lead) are found in stormwater runoff from highways and industrial land uses. Imperviousness (rooftops, roads, parking lots, etc.) increases the volume and velocity of stormwater runoff. Stormwater utility rates need to be based on something that is defendable, fair, and equitable for rate payers. For this reason, land use and/or imperviousness are a good basis forestablishing stormwater utility rates. There are predominantly 2 stormwater utility rate types. These include a flat fee and variable fee. 1. Flat Fee — where the rate payer fee is the same for each parcel regardless of land use, acreage, imperviousness, stormwater improvements, etc. This method is simple since everyone pays the same amount. Collection is tied to an existing database which reduces billing costs and duplication errors. However, this method can be difficult to justify and is not considered fair or equitable among rate payers since it does not consider differences of parcel size, land use, and stormwater runoff. 2. Variable Fee — where the rate payer user fee varies depending on the parcel based on acreage, assessed value, land use, impervious area, or a combination of these. a. Acreage Based — a flat rate per acre. This method is simple since everyone pays something and it is based on readily available acreage data. However, it can be difficult to justify and is not considered fair or equitable among rate payers since it does not consider differences in land use and stormwater runoff. b. Assessed Value — equivalent to a percent of assessed property value. This method is simple since everyone pays something and it is based on readily available assessment data. However, it can be difficult to justify and is not considered fair or equitable among rate payers since there is no direct relevance between a property's assessed value and stormwater runoff. Nor does it consider differences in land use. c. Land Use — tiered flat rate or runoff coefficient. Both land use methods are effective since they take into consideration land 18 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 use and its general relationship to stormwater runoff. Although collection is based on an existing database of land use codes, the rate assigned to each code is an average for typical land use and may not reflect actual imperviousness and its impact on stormwater runoff. d. Impervious Area — average impervious area, actual impervious area for all land use types, or actual impervious area for only a particular land use type. Each of these methods takes into consideration either the average or actual impervious area for each land use. Impervious area is considered an indicator for both the quantity and quality of stormwater runoff. Since the rate is based on the contribution to stormwater runoff, the various impervious methods are the most fair and equitable of all the rate types. However, since impervious area data may not be readily available, developing the initial database can be more expensive and time-consuming effort than land use -based methods. Assessing fees based on impervious area is the most common stormwater utility rate method throughout the United States and in Indiana. Since it is the best indicator of amount and quality of stormwater runoff, it is considered the most defendable, fair, and equitable for rate payers. Once the initial impervious database has been developed, newly constructed impervious areas may be added to ensure the database is accurate. RECOMMENDATION #5 It is recommended that the City implement a stormwater utility fee that is based on the total amount of impervious sulfate on each parcel 15 a fillyiIUTY1RgTE,STRUGTURE- SSUMPTIONS BChristopher 8. Burke Engineering, LLC In order to estimate potential revenues needed to be generated from various property types to meet the program costs discussed in Chapter 3, a rate structure database was created. Aside from its main purpose, the database was created in a way to enable the user to change some parameters and instantly see its effects on the required fee per ERU and how a given scenario may change the share of revenue generated from each land use property type. The following assumptions were made when developing the different scenarios in the rate structure database. 1. The Study Area (Figure 5-1) was defined as the portion of City of Carmel under the jurisdiction of City of Carmel government. The "hole" shown in Figure 5-1 is the Home Place Neighborhood, and properties in this area were not included in the analysis. 19 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 Figure 5-1 City of Carmel Stormwater Utility Service Area 2. The parcel data provided by City of Carmel included a field classifying each parcel into a property class. The entries in this field were the property class codes used by the State of Indiana's Property Tax Management System. There were 483 parcels that were not attributed with a property class; in this case, CBBEL assigned a property class based on examining 2012 aerial photography, surrounding parcels, and professional judgment. 3. Digitization for a small sample of residential structures was undertaken for the purpose of establishing an ERU (see Section 5.2) 4. Public roads and railroad lines were neither digitized nor assessed. 2 011c"1-., TION±' rffB Christopher B. Burke Engineering, LLC CBBEL used 2012 aerial photography and the most recent parcel data to develop the ERU value for the City's study area. To summarize, the calculated ERU value was based on a representative sample of impervious surfaces of Residential (non -Condominium) properties. 23,375 parcels were classified as Property Class 510 (Single Family Residential); however, SFR Parcels showing rooftop areas <400 ft2 were not used in the analysis, resulting in 22,200 SFR properties. The first step in calculating the ERU value was the determination of average and median rooftop areas using the available rooftop data for the 22,000 SFR parcels. Expressed as area of rooftop on the parcel, the average was calculated to be 2,840 ft2 and the median value was calculated to be 2,689 ft2. The second step consisted of digitizing all impervious areas on a sample set of SFR properties. 125 (or 0.56%) SFR properties were randomly selected from areas in the city, mostly located in subdivisions, but the selection was based on a ratio of number of properties within each subdivision. These selected SFR parcels ranged in size from 0.09 acres to 4.7 acres. The impervious areas for those parcels were then digitized, and classified as either 'Rooftop' or 'Non - Rooftop' impervious areas. The median total impervious area for this sample set was calculated to be 4,087 ft2. 20 1 f I1I "' i i J _Oh Li -�2IA•'tr1 Figure 5-1 City of Carmel Stormwater Utility Service Area 2.

The median total impervious area for this sample set was calculated to be 4,087 ft2. 20 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 The ratio of total impervious area to rooftop area was then calculated for each of these parcels in the sample set. The average of the ratios of total impervious area to rooftop area for the sample set resulted in 1.5426. The average ratio of total impervious area to rooftop area from the sample was then multiplied by the median rooftop area from the entire 22,200 SFR parcels to calculate an estimated ERU of 4,147 square feet. As can be seen from a comparison of the sample digitization results and the rooftop -based analysis, there is a good agreement between the two methods used. Based on the results of these calculations, the ERU for City of Carmel stormwater utility jurisdictional area is determined to be 4,150 square feet. Each SFR property is typically assessed a minimum of one ERU, regardless of the size of impervious area on each property. Properties with duplexes and triplexes were also assessed a minimum of one ERU. RECOMMENDA TION, 46 It is recommended that the City use an ERU value set at 4,150 square feet. 5i3 IMPyERVIO IStAREAGAICUUATIONIFOR'INON--RESIDENTIACIPROPERTIES a To calculate the impervious area of non-residential parcels, property class values for all 1,396 non-residential, non-agricultural, and non -vacant parcels were isolated in the GIS and the actual impervious areas were digitized. The determination of property classes was based on data provided by Hamilton County. In the 483 instances where no property class information was available, property classes were assigned based on visual inspection of aerial photography and professional judgment. Impervious areas were then converted to centroids, summed, and spatially joined as a field in the parcel layer. As part of the digitization efforts, reasonable care was taken when tracing around edges of impervious areas. Resolution of the provided aerial photography limits the accuracy in these efforts. If a property was noted as having a property class that indicated vacancy, then it was assumed that these parcels were vacant and the impervious area that may have existed may not have been digitized. Digitization was based on the Hamilton County building footprint layer from 2004 (updated in 2007). Some of these footprints were modified during the digitization based on visual inspection. 15.4:*ACTORS'IAFFECTI NGICHE1REVENU E R Christopher B. Burke Engineering, LLC As discussed earlier in the report, the stormwater budget recommended by CBBEL is calculated at $2,867,000. However, several factors may influence the overall generation of revenue which may include, but not be limited to, the following: 21 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 !TB Christopher B. Burke Engineering, !LC • Rate of Non -Payment — Based on conversations with other Indiana Stormwater Utilities, it can be expected that as much as 10% of those receiving a utility bill will be delinquent in their payment or may not pay at all, at least in the first few years. The current budget and scenarios considered do not include an allowance for the noted potential loss of revenue. • Administrative/Enforcement — The Stormwater Management Board should expect to receive several inquiries from residents, once the residents receive their initial stormwater bills. Responding to these inquiries via telephone calls or emails will require paid administrative staff. Administrative or enforcement costs that are associated with the actual collection of unpaid or delinquent utility bills may further reduce the revenue. These have not been included in the current rate calculations. • Parcel Database Cleanup — There may be errors in the City's parcel database that affect the accuracy of billings. Upon taking the time to correct errors in the parcel database, one may discover that contiguous parcels which were once being charged multiple fees, have now been consolidated into one parcel, and therefore, one fee. Additionally, any other inaccuracies discovered during this cleanup process may result in changing revenues. • Vacant Property Classes — As previously mentioned, parcels which indicated a vacant property class were not digitized. During the digitization process; however, some parcels were identified as having impervious area, though classified as vacant. In cases where these properties were noticed, impervious areas were digitized, and property class was modified. • Razed Structures — Structures that have been removed after the creation of the Rate Study may bring this to the administrator's attention, causing for a recalculation of their fee. • New Structures — Structures that have been added after the creation of the Rate Study will need to be charged the appropriate fee, which in most cases; will consist of changing from a vacant property class to a non -vacant property class. • Credits — If economic incentives to reduce user fees are offered by the City in the future, the overall revenue will likely be reduced. The cost associated with administering a system of incentives must also be considered. 22 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 i5 5 PARCEL' DATABASEISURWIARXVAPD!STATISTiICS Based on the latest parcel database provided to CBBEL, there are 32,201 parcels within the Study Area in City of Carmel.

Burke Engineering, LLC 24 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 ',5.6,4UTILINIRATE.STiRUCTURE !B Christopher B. Burke Engineering, LLC CBBEL considered various rate structure scenarios for determining the proposed rates; this was accomplished by performing "what -if" scenarios in the database, adjusting ERU Multipliers for specific property classes. It was determined that the most fair and equitable scenario involved charging property classes in the following manner: • Residential (non -Condominium) = 1.0 ERU • Condominiums = 1.0 ERU • Agricultural Properties = 1.0 ERU • Commercial, Industrial, Tax Exempt Properties = Rate determined as multiples of ERU based on the amount of impervious area, but subject to a minimum of 1.0 ERU • Vacant properties (all property classes) = 0.0 ERU This rate structure attempts to limit the assessment of utility fees to those properties that have impervious areas. The results of using these parameters show that the monthly fee for a Residential Property (equal to 1 ERU) would be assessed a monthly fee of $4.95, or $59.47 annually. Properties that are being charged based on amount of impervious areas would be charged accordingly (multiples of ERU, with a minimum ERU set at 1). Figure 5-4 shows the percentage of total revenue that would be collected from each property class.

This range is below the normal customer willingness to pay for a moderate stormwater management program according to the survey. For this reason, a stormwater utility is considered adequate to fund a stormwater program. Based on the detailed rate study performed as part of this study, a utility rate per ERU per month for City of Carmel is determined to be$4.95 per ERU per month. Compared to several other communities in Indiana (Appendix 4), this utility rate value is in the middle of the scale. )518 ii/SING Til E RATE'ST,UUYiUATABASE^TQIDEVELopa;iBILLIN'G'D'ATABASE FBChristopher B. Burke Engineering, LLC Using the data provided in the Rate Study Database to develop an actual Billing Database should be exercised with caution. The Rate Study Database is typically based on the best available data at the time of the study, without much correction or validation, and serves only as a tool to develop a fair and equitable method for calculating stormwater user fees for the general population. The parcel data provided by the staff of City of Carmel GIS Department may have inherent errors that must be addressed before proceeding with the creation of an updated billing database. While many of these issues may be minor, the issues may raise points of contention among the Rate Payers. The points listed 26 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 below may provide additional insight regarding the potential discrepancies that were discovered during the creation of the Rate Study Database. • New Development - Impervious areas were digitized based on the property classes attributed to each parcel in the supplied parcel data. There exist cases where development has occurred on parcels, but the property classes were not updated to reflect this development. Therefore, digitization of new impervious areas would not have occurred on these parcels. • Duplicate Parcel Numbers - More than 1 parcel share the same parcel number. In some cases, the duplicate parcels are contiguous and have the same owner. The parcel numbers should be resolved as the parcel number serves as the unique identifier when constructing the Billing Database. • Municipal Boundary — There are a few parcels that are on the edge of the boundary of unincorporated City of Carmel. To avoid incorrectly charging these parcels, one must determine which jurisdiction is responsible for these parcels. • Structures Occupying More than One Parcel — There are instances where a property owner, who owns 2 or more contiguous parcels, has built a structure spanning across 2 or more of these parcels. Because fees are determined by parcel, the property owner will be charged separately for each parcel of land upon which the structure spans. • Exclusion of Parcels — There are a number of parcels (mostly classified as exempt) that were excluded from the analysis because they appeared to be within a road right-of-way or railroad. It is unlikely that resolving and adding these parcels back into the Rate Study Database would affect the overall ERUs and consequently, the calculated fee. These parcels can be placed back into the analysis with relative ease, if needed. EBChristopher B. Burke Engineering, LLC Caps are used to set a maximum amount that any one rate payer would pay per parcel. This is often viewed by the general population as an unfair distribution of the stormwater fee. There are few communities in Indiana that have included caps in their stormwater utility. Credits (sometimes called economic incentives) are more common than caps in stormwater utilities. These may be used for the following: • Activities that go above and beyond the stormwater program requirements such as zero stormwater discharge or improvements to water quality (above and beyond that required by the ordinance or permit requirements); • Site planning, source control, or imperviousness reductions common to low impact development practices; 27 City of Carmel—Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 o Education and outreach as part of the school curriculum; e Voluntary retrofit of BMPs; or • Voluntary neighborhood efforts. CBBEL believes that establishing any maximum level on the amount of fees on properties as a result of application of the established City-wide ERU base rate is not in the best interest of the City. With regards to credits, CBBEL feels that, in general, economic incentives are a good idea to further the goals of the stormwater program. However, due to the magnitude of the task of establishing a credit program it is recommended that for now consideration of economic incentives are set aside for now but can be established at a later date as part of the stormwater utility implementation. RECOMMENDATION #8 It is recommended that the Citymot establish caps but consider establishing a basis for credits at a later date as part of the stormwater utility implementation. rB Christopher 8.

Burke Engineering, LLC 29 City of Carmel —Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 CHAPTER 6 SUMMARY OF RECOMMENDATIONS & NEXT STEPS The following is a summary listing of CBBEL recommendations as part of this Stormwater Program and Capital Improvement Budget Study and suggested next steps toward establishing a stormwater utility. 16 L(SUIVIMARYpF4RECQNIMENDATIQNS lbChristopher B. Burke Engineering, LLC Recommendation #1 It is recommended that the City seek legal counsel to determine whether to create a new Department of Stormwater Management or to expand the existing scope of services of the Municipal Sewage Works. Recommendation #2 It is recommended that the City create a dedicated funding source, such as a stormwater utility fee, to more effectively implement and meet the goals of their Rule 13 Program and to position the City to meet increasing expectations and requirements. Recommendation #3 It is recommended that the City continue to utilize the existing staff organizational structure to implement their Rule 13 program. Further, the City should supplement their existing staff by hiring a new Utility Administrator who should also serve as a GIS Technician to handle the increased workload for the stormwater utility as well as a new Vac Truck Operator to properly maintain the separate storm sewer conveyance system. Recommendation #4 It is recommended that the City adopt a stormwater program budget of $2,900,000 to meet their Rule 13 Program requirements and implement the identified Special Projects. Recommendation #5 It is recommended that the City implement a stormwater utility fee that is based on the total amount of impervious surface on each parcel. Recommendation #6 It is recommended that the City use an ERU value set at 4,150 square feet. Recommendation #7 It is recommended that the City adopt a stormwater utility rate structure based on charging residential properties 1 ERU and charging commercial, industrial, and tax exempt properties multiples of ERU based on their impervious area, with a monthly fee per ERU set at $4.95. 30 City of Carmel — Stormwater Program & Capital Improvement Budget Study DRAFT July 2013 Recommendation #8 It is recommended that the City not establish caps but consider establishing a basis for credits at a later date as part of the stormwater utility implementation. Christopher B. Burke Engineering, LLC This Stormwater Program and Capital Improvement Budget Study is an essential first step for City of Carmel as it decides whether a stormwater utility fee is the most appropriate funding mechanism to meet the stormwater regulatory requirements and manage stormwater. The following are the recommended steps to successfully establish a stormwater utility: Create Project Fact Sheets — a summary of the new items that could be funded with the stormwater utility including special projects such as Capital Improvement Projects (CIP), Community Sanitary Connection Funds, and Inspection & Maintenance of Older Stormwater BMPs. Each fact sheet would include background on the problem, description of the solution, estimated cost, and benefits. Public Information and Stakeholder Engagement — the support of the public and key stakeholders is essential to the successful implementation of the Stormwater utility. This includes: o Raise awareness of the cost to manage stormwater and regulatory requirements, o Illustrate the benefits of a dedicated funding source, o Establish a method to disseminate information and answer questions o Meet with key stakeholders, organized groups, and the media to diffuse opposition and dispel myths Pass Ordinances — to establish the stormwater utility and rate structure Create a Billing Database — similar to the rate study database, a billing database will need to be developed that includes the rate structure and rate fees Establish a Billing Method — determine if an existing utility billing method (property tax system or sewer utility) is appropriate billing method for the stormwater utility or if an independent billing system is needed Identify a method for Database Updates — the City will need to adopt policies and procedures to update the rate study and billing database Develop a System for Credits — identify types of economic incentives and application/promotion process 31 APPENDIX 1 STAFFING ORGANIZATION CHART This page intentionally left blank Drak Organization5l Chart for Proposed City of [armef5tormwater,Utility James Brainard, Mayor off nfmmd Ru kl3 Duly AWhented Re fesuuMe /elle Thomas 15e.5ro., nF.wee.
