Koch, Public Works Director D~ ~Yk-~ MEMORANDUM February 20, 2004 TO: FROM: Michael C. Van Milligen, City Manager Gus Psihoyos, Assistant City Engineer ..JQ. SUBJECT: Stormwater Management Utility Policies and Procedures Manual INTRODUCTION The purpose of this memo is to present the Stormwater Management Utility Policies and Procedures Manual prepared by City staff and COM, the City's stormwater utility consultant, to the City Council for review, discussion, and approval. This Policies and Procedures Manual provides the guidelines and framework under which the Utility will operate. In addition, the Manual identifies credits that may reduce a portion of a customer's Stormwater Utility Fee. BACKGROUND The City Council established a Stormwater Management Utility on February 27, 2003, pursuant to Iowa Code § 384.84( 1), with the passage of Ordinance No.7 -03. While the Ordinance provides the mechanism for billing and payment, adjustments to fees, accounting for capital contributions, and establishes a Stormwater User Fee Fund, the Policies and Procedures Manual identifies and clarifies the procedures for updating a customer's billing data file. Specificplly, the Manual covers procedures for: stormwater billing, fee adjustments, financial assistance, credits, and appeals. In Fiscal Year 2004, the City Council established two annual financial assistance programs within the Capital Improvement Budget intended to lessen the financial burden the stormwater user fee might impose on low-income residents and property tax exempt organizations. The financial assistance programs will be available as long as the City Council continues to budget, non-storm water utility fee funds to support them. In July, the City Council authorized the use of the low-income subsidy criteria used for refuse subsidies to be used for the stormwater utility fee. Therefore, a customer who meets Section 8 requirements, income is 50% or less than the medium income for Dubuque County, is given a 50% stormwater fee reduction. The Citizen Advisory Committee established by the City Council to discuss the City's stormwater management program and how it should be funded, unanimously recommended that, "Credits shall be given to those properties that provide storm water management actions that reduce the City's cost of storm water management." A stormwater credit is a percent reduction in a portion of a customer's Stormwater Utility Fee. For example, if a 20% credit is granted then the customer's stormwater fee will be reduced by 20%. DISCUSSION The Manual, intended for the City staff use, has five sections: Section 1 is an introduction with definitions, Section 2 establishes guidelines for customer account management, Section 3 describes fee adjustment procedures and financial assistance programs, Section 4 discusses credits, and Section 5 outlines the appeal process. Of the five sections, the credit section necessitates the most discussion. When the Stormwater Management Utility was passed in February of 2003, City staff promised to develop a policy that would provide up to a 50% credit for customers that take actions that reduce the City's cost to manage stormwater. The Stormwater Management Utility Policies and Procedures Manual specifically identifies the activities that warrant a credit and how much the credits will be. Moreover, the Manual provides the necessary forms and guidance for staff and customers to facilitate an efficient application and review process and ensure that the policy is applied equitably. City staff intends to keep the credit application process as simple as possible, employing principles of equity and reason. The credit policies have been developed to strike a delicate balance between simplicity, effectiveness, and equity. When discussing stormwater credits it is important to recognize that the Stormwater Management Utility is similar to the water, refuse, and sanitary sewer utilities in Dubuque. In each case, the City is providing citizens with a service and the customer's fee for the service is based on the cost to provide the service. While the water utility fee is established by measuring the cubic feet of water used by the customer and the refuse utility charge is based on the size and number of trash receptacles, the sanitary sewer fee is based on the measurement used by the water utility. And, the stormwater utility fee is based on a measurement of hard (impervious) surface areas. While the fairest way to establish a customer's stormwater contribution is to measure the rainwater that runs off each customer's property, it is cost prohibitive. Similarly, the sanitary sewer utility does not measure the actual amount of wastewater that each customer generates. Therefore, the stormwater utility makes use of a compromise by using the measurement of hard surface area to establish a customer's fee. A credit can increase the equitability of the utility fee because more than the amount of impervious area dictates the amount of rainwater that runs off a customer's property. Typically, residential customers do not have the necessary land or resources to implement, operate or maintain meaningful or quantifiable stormwater management facilities. Moreover, the City does not have the means to regulate or oversee individual residents to ensure that a credit is valid. For example, while the City could issue a credit for the use of a rain barrel, the City would be unable to verify that a rain barrel is installed properly or that it is empty prior to each rain. Therefore, only nonresidential customers are eligible for credits. Facility and Activity Credits The City's Stormwater Management System is funded through various sources, including the Dubuque Racing Association distribution, the general fund, bonds, fees, and the Stormwater User Fee. The City allocates money from each source to activities or facilities associated with stormwater management. Facility and activity credits are available if a customer's activity or facility is associated with City activities or services funded by the user fee. For example, although a customer might reduce the City's cost to maintain the floodwall by removing debris along the Mississippi River, a stormwater fee credit is not warranted because stormwater user fees are not used by the City to operate and maintain the floodwall. Table 1 is a summary of Facility and Activity credits, user fee funded activities categorized into the various components of the stormwater management system: administration, billing, operations and maintenance, Capital Improvement Program and NPDES program. T able 1. Summary of Facility and Activitv Credits Max. Facility and Activity Credits Credit Operation & Maintenance Generally, the maintenance of a catch basin requires annual inspection and sediment removal. Cleaning requires a vacuum truck and/or climbing Catch Basins into the catch basin. Climbing into the catch basin is a confined space 10% entry, requiring specific safety training per the U.S. Department of labor Occupational SafelY & Health Administration (OSHA). Maintenance of the storm sewer system consists of inspection, cleaning, Storm Sewer and general repairs. If a customer has the resources to inspect, clean and 21% repair a public storm sewer on private property, the customer may be eliGible for a Storm Sewer credit. The maintenance of manholes involves biannual inspection and cleaning Manholes and repairs as needed. If a customer has the resources to inspect, clean 3% and repair a public storm manhole on private property, the customer may be eliGible for a Manhole credit. Culverts and bridges provide conveyance for stormwater under roads and Culverts/ other structures. If a customer has the resources and expertise to inspect, 1% Bridges clean, or repair a culvert or bridge the customer may be eligible for a Culverts/BridGes credit. Creeks/ If a customer has the capabilities to remove sediment and debris from a 1% Streams creek or stream the customer mav be eliGible for a Creeks/ Streams credit. Capitallmorovement ProGram Capital improvement projects are projects built to improve the infrastructure or performance of the City's Stormwater Management Future Projects System. While it is unlikely that a private citizen would be allowed to 26% (Debt Relief) assist the City with implementing future facility construction or facility repair, under rare circumstances a customer may be eligible for a CIP credit. NPDES Public The City will consider the maximum credit for public education and Education & outreach and public involvement and participation tasks. 4% Outreach Public Activities considered must be applicable to the program outlined in the Involvement & City's NPDES Phase II permit. 4% Particioation Direct Discharge Credit The purpose of the direct discharge credit is to increase the equity of the Stormwater Management Utility. The goal of the user fee-funding source is to have each customer pay a fee based on the customer's runoff contribution to the total that the City must manage. Because there is a lower stormwater management cost associated with runoff from private property that discharges directly into the Mississippi River, Catfish Creek, South Fork Catfish Creek, or Middle Fork Catfish Creek a credit is warranted. The credit is limited to 20% because the City remains accountable for all stormwater, originating within the city limits, that discharges into waters of the United States. Private NPDES Permit Credit Certain private industrial operations are required to obtain an NPDES permit directly from the Iowa Department of Natural Resources. The permit requires the industrial operation to implement measures to manage stormwater runoff to minimize the pollutants associated with the stormwater runoff that leaves the property. The credit is in recognition of unique industrial activities that have stormwater management costs above and beyond other utility customer costs. The maximum NPDES credit is 10% and is available for a customer who maintains an NPDES General Permit No.1 or General Permit No.2 for stormwater discharge associated with an industrial activity. Private Detention Basin Credit - Peak Flow Preservation Current City policy requires that the peak flow of runoff from the site prior to development during 2, 10, and 100-year rains is preserved following development. The peak flow preservation credit is available when a customer has developed detention basin preserves. While the preservation of peak flows has been a requirement for developments that are an acre or more in size since the mid-nineties, an inequity arises between sites developed prior and those developed after the City's detention policy. Without detention credits, newer developments pay twice; once as an increase in development costs and the loss of usable land and twice when paying the Stormwater Management Utility fee for services that, in part, result from poor stormwater practices on other customers' properties. The maximum peak flow preservation credit is 10%. A greater credit is not warranted because even though a developer preserves the peak flow, the largest volume of water leaving the site at one time does not increase as a result of development, the developer does not address the increase in the flow (other than the peak flow), volume, or velocity of stormwater runoff leaving the site. Private Detention Basin Credit - Peak Flow Reduction Another reason to offer a credit is to provide an incentive for a customer to reduce the need for the utility service. The peak flow reduction credit provides such an incentive for developers to provide more detention than is required by the City's current stormwater detention policy described above. A 4% credit is available for a twenty percent reduction in peak flows for each of the 2, 10, and 100-year rains resulting in a maximum peak flow reduction credit of 12%. Table 2 is a summary of stormwater fee credits. The City of Dubuque Engineering Division will accept applications from customers for credits. Applications (see Appendix C) will be made available in the Office of the Engineering Division. In most cases, engineering calculations are required to support credits. A registered professional engineer may be required to prepare some of the supporting application documents. Table 2. Stormwater Cre it ummary.

STORMWATER UTILITY FEE CREDIT APPLICATION ~ 16 18 20 2 ._~ CDM Stormwater Management Uttlity Policies and Procedures Manual Section 1 - Introduction The City Council of the City of Dubuque established a Stormwater Management Utility on February 27, 2003, pursuant to Iowa Code § 384.84(1), with the passage of Ordinance No. 7-03. The ordinance provides authorization to establish and collect rates, fees, and charges for the services and facilities provided by the Utility. The Ordinance also declares that the Utility is to provide benefits and services within the incorporated city limits, including the provision of adequate collection, conveyance, detention and treatment systems, hazard reduction to property and life resulting from stormwater runoff and flooding, improvement to the general health and welfare through the reduction of undesirable stormwater conditi ons. The Ordinance establishes a mechanism for billing the costs of operating and maintaining the Stormwater Management Utility, and financing the necessary repairs, replacements, improvements, and extensions. The Ordinance provides the mechanism for billing and payment, adjustments to fees, accounting for capital contributions, and establishes a Stormwater User Fee Fund. This Policies and Procedures Manual provides the guidelines and framework under which the Utility will operate. The Policies and Procedures Manual is intended to identify and clarify the procedures for billing fees and updating the billing data file.

CDM Stormwater Management Utility Policies and Procedures Manual 1.2 Responsibility The City Council is the governing body of the Stormwater Management Utility. The City Manager, through the Public Works Director, is responsible for directing, managing and controlling the System. This includes the day-to-day operation of.-the Utility and other associated ordinances and regulations, and implementation of the policy directives of the City Council regarding the Stormwater Mana gement Utility. 6 __M_, CDM Stormwater Management Ulility Policies and Procedures Manual Section 2 - Storm water Billing 2.1 Stormwater User Fee Fund A Stormwater User Fee Fund has been established for the collection of all fees and charges by the Utility. This fund is for the exclusive use of the Stormwater Management System, including, but not limited to the following: . Operation and Maintenance of the Stormwater Management System. Operation and maintenance activities include street sweeping, catch-basin cleaning and repair, storm sewer repair, channel clearing, detention basin sedimentation removal, ditch and swale mowing, channel reconstruction, and erosion repair. . Costs of Construction incurred in connection with providing capital improvements to the Stormwater Management System. As part of the improvements the City may authorize the construction of curbs, gutters, catch basins, channels, drainage swales, storm sewers, culverts, detention basins, pump stations, as well as other stormwater related facilities. . Administrative costs associated with the management of the Stormwater User Fee Fund (e.g., billing, postage, collection). While there is no intent at this time to charge for these services, also eligible are utility management, legal costs, record keeping, City financial services, and computer re ports. . Debt service for financing. . Planning and engineering. . Cost incurred by the City to comply with all federal, state, and local stormwater regulatory requirements. Dubuque manages stormwater using a variety of funding sources: the Stormwater Management Utility, general fund, Dubuque Racing Association distribution, revenue, bonds, permits, and fees. Therefore, there typically are stormwater management services provided by the City not specifically funded by the Stormwater Management Utility. 2.2 Utility Customer Classification A Stormwater User Fee will be imposed upon each developed lot and parcel within the City for stormwater services and facilities provided by the City. For purposes of imposing the Stormwater User Fee, all developed lots and parcels within the City are classified into, or a mixture of, the following two customer classes: Residential Develooed Property Single Family Mobile Home Multi-family Condominiums Nonresidential Develooed P rooertv Governmental Institutional (tax exempt) Commercial Industrial Stormwater User Fees are not imposed on public streets including federal expressways, state roads, or local streets, roads, and alleys. In addition, Stormwater User Fees are not imposed upon impervious public facilities located within right-of- ways, including sidewalks, curbing, street crossings, or bike paths. 7 CDM Stormwater Management Utility Policies and Procedures Manual 2.3 Stormwater User Fee Stormwater User Fees are assessed to Utility customers based upon a customer's user classification described in the previous subsection. Residential Developed Property is billed based on a tiered rate structure. The average single-family residential property will be billed 1 Single Family Unit (SFU). An SFU is equal to 2,917 square feet of impervious area (statistically developed average for single family homes in the City of Dubuque). The Ordinance establishes the rate to be charged for the Stormwater Use Fee for equivalent residential units. Single-family residential properties will be billed the following percentage of the SFU based on the totaJ square footage of impervious area for the particular property: Single-Family Residential Property Percentage of SFU Rate Impervious Area Total (fe) 1,471 or less . 50% 1,472-4,374 100% 4,375 or more 150% Note: Values from Ordinance No. 7-03, adopted on 02-27-03, are subject to change. Non-single family residential property will be billed the following percentage of the SFU rate multiplied by the number of dwelling units on the property; Non-Single Family Residential Property Percentage of SFU Impervious Area Total (ft2) Rate Multifamily (excluding condominiums and 42% mobile homes) Condominium 83% Mobile Home 65% Note: Values from Ordinance No. 7-03, adopted on 02-27-03. are subject to change. Nonresidential customers will be billed based on single-family units. The user fees will be assessed as follows: . The fee imposed for Developed Nonresidential Properties as defined herein is the rate for one SFU, multiplied by the numerical factor obtained by dividing the total impervious area (square feet) of a nonresidential property by the impervious area for one SFU. . The minimum fee for any Developed Nonresidential Parcel is equal to the rate for one SFU. 8 - ,,_...-~ aJM Stormwater Management Ulility Policies and Procedures Manual 2.4 Billing and Payment The Stormwater User Fee for property will be billed and collected monthly with the City's utility bill for those properties that use other City utilities. Properties not utilizing City utilities may be billed semi-annually rather than monthly. 2.5 Delinquent Charges and Non-Payment Penalties Stormwater User Fees not paid when due will be handled in the same manner as delinquent utility fees for other City-provided services as provided in section 44-86 of the Code of Ordinances. 2.6 Billing Data Update The Public Works Director is responsible for routine updates to the billing data to account for the addition or demolition of impervious areas for Developed Residential and Nonresidential Properties if brought to the attention of the Engineering Division. The City Manager will ensure that updates to the billing data are performed continuously or on a routine schedule. The Public Works Director will obtain impervious area information for Developed Nonresidential Properties as part of the site plan review and building permit application processes. Permit applicants must furnish impervious area information for building structures, driveways, curbs, sidewalks, patios, or other covered surfaces to be constructed. This information must be included on the construction drawings submitted to the Public Works Director or on a separate form submitted with the permit application. The issuance of a water meter for residential properties or 90 days after the issuance of a building permit for nonresidential properties initiates stormwater services and billing for Stormwater User Fees. If neither a water meter nor a building permit is issued, and the City determines a development is substantially complete or has been halted for at least three months, the user fee will also be initiated. The first utility bill will include fees back to the issuance of the water meter or 90 days after the building permit was issued. The Engineering Division is responsible for the assignment of SFUs to the new customer and the updating of the billing database. 2.7 Service RequestsfDiscontinuation of Service For customers requesting utility service, Utility Billing will update the utility billing system data file with the new customer's name, billing address, and other pertinent information, and check to ensure that the account is active and chargeable. For a request for discontinuation of utility service in a tenant situation, the Utility Billing will update the current customer information from the account. Stormwater accounts will remain active and chargeable at all times. S tormwater accounts may only be removed from the billing database when the Public Works Director determines that a customer has removed all impervious area from a formerly developed property and has returned the property to its previously undeveloped condition. 9 CDM Stormwater Management Uülity Policies and Procedures Manual 2.8 Utility Billing Guidelines General billing guidelines are described as follows: . Residential multifamily, such as condominiums, apartment complexes, and trailer parks, are sometimes served by water meters in the name of the owner of the parcel. In such cases, the number of SFUs is assigned to the master account and billed to the property owner. However, the liability for payment of the Stormwater Management Utility Fee attributable to that property is joint and several as to the owner and any occupant. . Multiple meters on a single parcel where the meters have the same customer name assigned to it will have the uti lity fee billed to one account. . Many Nonresidential Developed Properties within the City of Dubuque have multiple customer accounts and multiple water meters on a single parcel (i.e., retail shopping centers). For these utility customers, the number of SF Us determined and assigned to each customer account will be on the basis of the percentage of the total impervious area that can be attributed to the individual customer. The percentage allocation is determined on the basis of the ratio of the customer's building area to the total building area. The area of impervious surface assigned to the customer is determined by multiplying the customer's percentage allocation of total building area by the parcel's total impervious area. The number of SFUs is calculated by dividing the customer's total impervious area allocation by the statistically determined value for one SFU (2,917 square feet). 10 --,,-- CDM Stormwater Management Utility Policies and Procedures Manual Section 3 - Fee Adjustments The City may grant an adjustment when a customer identifies incorrect information contained in the City's billing database. Both residential and nonresidential customers can apply for adjustments. "-" 3.1 SFU Adjustment Any customer who has paid stormwater user fees and believes that the SFU established for the customer's account is incorrect, may apply for an adjustment. In addition, an adjustment may be appropriate if a customer demonstrates that rainfall that occurs on an impervious area does not generate runoff (has no outlet), is completely watertight, and has at least 18 inches of freeboard. This adjustment is for unusual structures, such as swimming pools, hazardous material storage areas, etc. For these specific cases, the SFUs will be adjusted by removing from the SFU calculation the amount of impervious area that does not generate runoff. An adjustment may be warranted if a customer demonstrates that on-site gravel is not compacted, not used for vehicular traffic, and not impervious such as areas used for landscaping. However, all compacted gravel areas (drives, storage areas, etc.) are considered impervious areas, and as such, no adjustment will be granted. The Public Works Director will make the decision regarding the intended purpose of gravel areas. 3.1.2 Residential Customer A residential customer who believes the SFU component used to calculate the customers user fee is incorrect may apply for an adjustment using Stormwater Management Utility Form No.1 available at the City Engineering Division office, City Hall. 3.1.3 Non-residential Customer A nonresidential owner who believes the SFU component used to calculate the customers user fee is incorrect may apply for an adjustment using Stormwater Management Utility Form No.2 available at the City Engineering Division office, City Hall. 3.1.4 SFU Adjustment Application Process Requests for adjustment of the stormwater user fee must be submitted in writing to the Public Works Director. A customer may request an adjustment for determination of total impervious area, the calculation of the stormwater management charge, and/or the allocation of the charge among several occupants, if applicable. The first step in the adjustment process is a review of the City's calculation of the impervious area. The Public Works Director may request the customer to provide supplemental information including survey data prepared by an Iowa registered Professional land Surveyor that shows the amount of impervious area and compacted gravel area on a parcel or engineering reports prepared by an Iowa registered Professional Engineer. Failure to provide such information may result in the denial of the adjustment request. 11 CDM -- Stormwater Management Utility Policies and Procedures Manual The Public Works Director will respond in writing to all adjustment requests within 90 days after receipt of the request. The response will provide an explanation of adjustment approval or denial as well as requests for additional information. The denial of an adjustment may be appealed to the City Manager, and ultimately to the City Council, as provided in Section 5. Adjustments will be applied to a customer's account upon approval. An adjustment may be retroactive to the beginning of the City's current Fiscal Year. A pending application for adjustments shall not constitute a valid reason for non-payment. Appendix B contains Stormwater Management Utility Forms for the adjustment application process. 3.2 Financial Assistance Adjustment In Fiscal Year 2004, the City Council established two annual financial assistance programs within the Capital Improvement Budget intended to lessen the financial burden the stormwater user fee might impose on low-income residents and property tax exempt organizations. The financial assistance will be available as long as the City Council continues to budget, non-storm water utility fee funds to support the financial assistance programs. Financial assistance can be retroactive to the beginning of the City's current Fiscal Year. A customer may be eligible for financial assistance if: . The customer qualifies as a low income resident; or . The customer qualifies as a property tax-exempt organization; and . The City Council has budgeted appropriate, non-storm water utility fee funds to support the financial assistance programs. Customers who wish to apply for the low-income assistance program should complete Stormwater Management Utility Form No.4 available at the office of the Public Works Director and return it to the Utility Billing Department. Additional documentation is required to qualify for the program. The customer should contact the Utility Billing Department for full details. Property tax exempt customers should obtain Stormwater Management Utility Form No. 5 available in the office of the Public Works Director, complete the form, and return it to the Public Works Director for review. Customers that fall into one of the following classes as identified in the Iowa Code 427.1 may be eligible for a property tax-exempt fee reduction: federal and state property; municipal and military property; public grounds and cemeteries; libraries and art galleries; property of religious, literary, and charitable societies; property of educational institutions; and public airports. 12 -- --. - ~-_... ._-~ CDM Stormwater Management Utility Policies and Procedures Manual Section 4 Credits Rain and the resulting stormwater runoff is difficult to quantify and control. The quantification of stormwater runoff is based in science, statistics, assumptions, and experience. Volumes of literature have been produced and contTI;ue to be written on hydrology and stormwater management. There are as many different methods and opinions as there are components of stormwater management. It is, however, widely recognized that the level of impervious surfaces correlates di rectiy with increased levels of stormwater runoff. The City intends to keep the credit application process as simple as possible, employing principles of equity and reason. The credit policies have been developed to strike a delicate balance between simplicity, effectiveness, and equity. A stormwater credit is a reduction in a portion of a customer's Stormwater Utility Fee. To be eligible for a credit, the customer must demonstrate that the customer's existing or proposed stormwater facility or the customer's action reduces the City's stormwater program needs funded by the user fee. Credit eligibility is determined on a case-by- case basis. Typically, residential customers do not have the necessary land to provide meaningful, quantifiable stormwater management facilities or the resources to implement, operate or maintain such facilities. Moreover, the City does not have the means to regulate or oversee individual residents to ensure that the credit is valid. For example, while the City could issue a credit for the use of a rain barrel, the City would be unable to verify that a rain barrel was properly emptied after each rain. Therefore, residential customers are not eligible for credits. Appendix C is the application for Utility fee credits. Upon approval of a stormwater credit, the credit will be given at the next billing. A credit may be retroactive to the beginning of the City's current Fiscal Year if it can be shown that the justification for the credit was in place at that time. 4.1 Facility and Activity Credits Eligible Facility and Activity credits are based on stormwater expenses funded using the stormwater utility fee over the first five years of a twenty-five year planning period. Table 1 presents the City's stormwater costs that will be funded by the utility for the initial 5-year period. Costs are categorized into the various components: administration, billing, operations and maintenance, Capital Improvement Program and NPDES program for both system-wide and local storm water systems. Stormwater facilities are subdivided into two classifications for establishing the appropriate credit. Local stormwater facilities are defined as facilities that manage storm flow from upstream drainage areas of 1 square mile or less. System-wide facilities are defined as facilities that manage storm flow from upstream drainage areas greater than 1 square mile. Table 2 shows the local and system-wide breakdown of stormwater management activities funded by the Stormwater Utility Fee. The applicability of system-wide credits will be based on the ratio of the drainage area tributary to the stormwater facility or activity to the typical major drainage system area in 13 CDM Stormwater Management Utility Policies and Procedures Manual the City of Dubuque, approximately 5 square miles. For example, a facility with an upstream drainage area of 2.5 square miles would be eligible for half (2.5/5 = 0.5) of the system-wide credit. The City's Stormwater Management System is funded throUgh various sources, including the Dubuque Racing Association distribution, the general fund, bonds, fees, and the Stormwater User Fee. The City allocates money from each source to activities or facilities associated with stormwater management. Nonresidential customers are only entitled to Facility and Activity credits for facilities or activities that are associated with the City's services funded by the user fee. In order to determine the potential credits available to a customer, it is important to identify how much of the utility budget is allocated toward each of the user fee-funded activities. Potential credits are rounded to the nearest whole percent with a minimum of 1 percent allowed for each activity. 4.1.1 Stormwater Management Administration & Engineering The administration and engineering services performed by the City cover a wide range of activities. The cost of administering the Stormwater Management Utility is mostly funded by the Utility fee, while the processing of bills is being cost shared with the three existing City utility services: water, sanitary, and refuse. The stormwater share of this cost is being fully funded by the stormwater utility fee. These program costs are reflected in Table 1. Because billing of the Utility covers the entire City equally, it is considered a system-wide cost. Bills will be sent to each customer on a monthly basis regardless of any other activities the customer undertakes to reduce the City's Stormwater Management Program cost, so no credit is available. Engineering activities include handling citizen inquires or complaints, providing technical support to the City Council, implementing improvements defined in the stormwater master plan, emergency response to flooding, inspection services, and project management. Funding for these services comes from the existing general fund and is likewise not eligible for credits. (Maximum Credit = 0%) 4.1.2 Operations & Maintenance The City has significantly increased the amount of operation and maintenance it performs in order to meet the NPDES - Phase II water quality requirements and system maintenance needs. Existing general fund contributions to operation and maintenance are continuing at their current budget levels but are being supplemented in several areas by the stormwater utility fee. Provided below is a breakdown of the supplemental activities funded through the user fee. Catch Basin Ooeration and Maintenance The majority of catch basins serve an upstream drainage area of 1 square mile or less. However, it is possible that a group of catch basins serve a drainage area larger than 1 square mile. Therefore, the local versus system-wide split is 90/10, respectively. Generally, the maintenance of a catch basin requires annual inspection and sediment removal. Cleaning requires a vacuum truck and/or climbing into the catch basin. Climbing into the catch basin is a confined space entry, requiring specific safety training per the U.S. Department of Labor Occupational Safety & Health Administration (OSHA). Activities performed by individual customers that reduce the frequency or cost of catch basin and storm sewer cleaning may be eligible for a credit. The maximum potential 14 _.~ -~. ._-._.._-,-~~_._- CDM Stormwater Management Uülity Policies and Procedures Manual local credit is 9 percent. An additional 1 percent credit may be available for the system- wide credit. (Maximum Credit = 10%) Stonn Sewer Maintenance Maintenance of the storm sewer system consists of inspection, cleaning, and general repairs. Inspection and cleaning of the storm sewer system is planned to occur at a rate of 20 percent per year. The City has approximately 80 miles of storm sewers ranging from 12 to 24 inches in diameter. Sewers of that size typically convey small areas of local drainage, less than or equal to 1 square mile, and would be considered local storm sewers. There is approximately 20 additional miles of larger storm sewers. If a customer has the resources to inspect, clean and repair a public storm sewer on private property, the customer could be eligible for O&M storm sewer credit. The maximum credit is 17 percent for a local facility and with an additional 4 percent credit for a system-wide credit. (Maximum Credit = 21%) Manhole Maintenance The maintenance of manholes involves biannual inspection and cleaning and repairs as needed. If a customer qualifies, the maximum local credit is 2.5 percent and with an additional system-wide credit of 0.63 percent. (Maximum Credit = 3%) Culverts Culverts provide conveyance for stormwater under roads and other structures. Sediment and debris build-up can reduce the design capacity and cause road over- topping or upstream flooding. Road over-topping has a system-wide affect by limiting access for emergency vehicles and other traffic. Therefore, all culvert maintenance costs have been allocated as system-wide. Through 2008, the City plans to spend less than 1 percent (0.45%) of the stormwater utility fe e on culvert maintenance. As with storm sewers and manholes, it is unlikely that there will be opportunities for private activities to reduce the City's cost for maintaining culverts. However, if a nonresidential customer has the resources and equipment, the maximum credit for culvert maintenance is 1 percent. (Maximum Credit = 1%). Creeks/Streams The City of Dubuque has approximately 65 miles of major creeks and streams. Creeks and streams provide the majority of the stormwater conveyance in the System. Creek bank and stream bank erosion increase the total suspended solids load, which increases turbidity, increases the amount of maintenance required for detention basins and can cause other sediment problems downstream, such as the silting in of dams or culverts and bridges. Although erosion problems are usually localized, creeks and streams typically serve drainage areas larger than one square mile. Therefore, the entire 0.45 percent of stormwater utility fees designated for creeks and streams through 2008 has been budgeted as a system-wide cost. Opportunities for private customers to reduce the City's costs for creek and stream maintenance are limited due to the activities and equipment required. However, if a customer has the capabilities to remove sediment and debris from a creek or stream, the maximum credit is 1 percent.

NOTE: The maximum credit per account is limited to 50% of the billing units. ~ 16 4.1.3 Capital Improvement Program Capital improvement projects are projects built to improve the infrastructure or performance of the City's'Stormwater Management System. They can include storm sewer expansions or upgrades, detention facilities, pump stations, bridge replacements and channel reconstruction. Approximately 26 percent of the stormwater utility fee is designated for capital improvement projects and associated bond retirement. Approximately 90 percent of these projects are classified as system-wide and 10 percent are local. Customers who qualify may receive a credit of up to 3 percent (2.6%) for local projects and an additional 24 percent (23.6%) for projects classified as system-wide. However, it is unrealistic that a customer would have the private resources to assist with the construction of a public stormwater facility. Moreover, it is unlikely that a private citizen would be allowed to assist the City with implementing future facility construction or facility repair. Only under extremely rare circumstances would a customer be eligible for a CIP credit. (Maximum Credit = 26%) 4.1.4 NPDES The EPA has listed the following six minimum control measures that communities must implement as part of its municipal stormwater management program: public education and outreach on stormwater, public involvement and participation, illicit discharge detection and elimination, construction site stormwater runoff control, post-construction site stormwater management in new development and redevelopment and pollution prevention/good housekeeping for municipal operations. Public education and outreach and public involvement and participation make up approximately 50 percent of the budget for EPA compliance. The remainder of the budget is distributed equally among the remaining tasks. The City will consider credits for public education/outreach and public involvement/participation tasks. The maximum credit for each of these tasks is 4 percent. Activities considered must be applicable to the program outlined in the City's NPDES Phase II permit. There are no opportunities for credits on the remaining 4 minimum control measures because these activities have a significant engineering component and must be conducted by City staff, consultants, or contractors. (Maximum Credit = 8%) 4.2 Direct Discharge Credit The maximum direct discharge credit is 20% and is available for the portion of a property's impervious area that is contiguous to (or contains) and discharges stormwater directly into, the Mississippi River, Catfish Creek, South Fork Catfish Creek, or Middle Fork Catfish Creek. Runoff that passes through a public or private drainage facility such as a detention basin, ditch, or drainage way prior to discharging into one of the receiving waters identified above is not considered direct discharge. A greater credit is not available because the City remains responsible for stormwater originating within the city limits that discharges into waters of the United States. The direct discharge credit will remain valid until the property is redeveloped or re- graded.

There are two concurrent credits available: peak preservation credit and peak reduction credit. While the private detention basin credit will remain valid until the property is redeveloped or re-graded, an annual inspection report must be filed in the office of the Public Works Director by June 30th. If a customer fails to file the required inspection report or if a random City inspection finds that the detention basin does not operate as outlined in the original credit application, the City will send a letter informing the customer of the required action to avoid revocation of the credit. If the property owner fails to take the required action, the credits will be revoked. In the case where inspection reveals that the detention basin does not operate as outlined in the original credit application, the credits will be revoked retroactive to the most recent inspection documentation that found the detention basin operational as outlined in the original credit application. The credit may be restored when the customer takes the required actions and provides documentation that detenti on basin functions properly. 4.3.1 Peak Flow Preservation Credit The maximum peak flow preservation credit is 10% and is available when a detention basin preserves the peak flow of runoff from the site during 2, 10, and 100-year rains. In other words, the credit is available when the peak flow of runoff during 2, 10, and 100-year rains following development does not exceed the peak flow of runoff that occurred prior to development. While the preservation of peak flows has been a requirement for developments that are an acre or more in size since the mid-nineties, an inequity arises between sites developed prior and those developed after the City's detention policy. Without detention credits, newer developments pay twice; once as an increase in development costs and the loss of usable land and twice when paying the Stormwater Management Utility fee for services that, in part, result from poor stormwater practices on other customers' properties. A greater credit is not warranted because even though a developer must preserve the peak flow (the largest volume of water leaving the site at one time does not increase as a result of the development) a developer does not address the increase in the flow (other than the peak flow), volume, or velocity of stormwater runoff leaving the site due to the development of the property. (Maximum Credit = 10%) 4.3.2 Peak Flow Reduction Credit The maximum peak flow reduction credit 12% and is available for a detention basin that reduces the peak flow of runoff from the site by at least twenty percent during 2, 10, and 100-year rains. In other words, the peak flow of runoff during 2, 10, and 100-year rains following development is twenty percent lower than the peak flow of runoff that occurred prior to development. A 4% credit is available for a twenty percent reduction in peak flows for each of the three rain events. The credit is an incentive for a developer to provide more detention than is required by the City's stormwater detention policy. (Maximum Credit = 12%) ~ 19 CDM Stormwater Management Utility Policies and Procedures Manual 4.4 Private NPDES Permit Credit The maximum National Pollution Discharge Elimination System credit is 10% and is available for a customer who maintains an NPDES General Permit No.1 or General Permit No.2 for storm water discharge associated with an industrial--activity. Certain private industrial operations are required to obtain an NPDES permit from the Iowa Department of Natural Resources (IDNR). The permit requires the industrial operation to implement measures to manage stormwater runoff to minimize the pollutants associated with the stormwater runoff that leaves the property. The justification for the credit is in the recognition that some industrial activities have additional costs associated with stormwater runoff. They must manage both the quantity and quality of the stormwater runoff. 4.5 Credit Summary Table 3 is a summary of the Stormwater Management Utility credits that are available. Appendix C is the credit application packet and the specific requirements to obtain a credit. 4.6 Credit Application Process The City of Dubuque Engineering Division will accept applications from customers for credits. Applications are available in the Office of the Engineering Division at City Hall. In most cases, engineering calculations are required to support credits. A registered professional engineer may be required to prepare some of the supporting application documents.

The utility provides the City with the authorization to establish and collect just and equitable rates, fees, and charges for the services and facilities provided by the utility system. The ordinance also declares that the utility is to provide benefits and services within the incorporated city limits, including the provision of adequate collection, conveyance, detention and treatment systems, a hazard reduction to property and life resulting from stormwater runoff and flooding, improvement in general health and welfare through the reduction of undesirable stonnwater conditions and flooding, and improvements to stormwater, surface water and receiving water quality. No additional City staff personnel have been added to implement or manage the Stonnwater Management Utility. Therefore, City staff intends to keep the credit application process as simple as possible, employing principles of equity and reason. The credit policies have been developed to strike a delicate balance between simplicity, effectiveness, and equity. A stonnwater credit is a reduction in a portion of a customer's Stonnwater Utility Fee. To be eligible for a credit, the customer must demonstrate that an existing or proposed stormwater facility or a customer's action reduces the City's stormwater program needs funded by the user fee. Credit eligibility is determined on a case-by-case basis. Credits will not be allowed for any properties that do not pay a stormwater fee. Typically, residential customers do not have the necessary land or resources to implement, operate or maintain meaningful or quantifiable stormwater management facilities. Moreover, the City does not have the means to regulate or oversee individual residents to ensure that the credit is valid. For example: while the City could issue a credit for the use of a rain barrel, the City would be unable to verify that a rain barrel is installed properly or that it is emptied after each rainstonn. Therefore, only nonresidential customers are eligible for credits. Available Credits Credits are divided into four types: facility and activity credits, direct discharge credit, private detention basin credits, and a private NPDES credit. Table 1 is a summary of stormwater fee credits. Table 2 outlines the documentation required to apply for a specific credit. The maximum credit per account is limited to 50% of total billing units. ~ 2 ~ "~_. Stormwater Management Ulility Fee Reduction Credft Application Table 1. SummarY of Available Stormwater Fee Credits Maximum Credit Description Available Credit Facilitv and Activitv Credits Ooeration & Maintenance .- Generally, the maintenance of a ætch basin requires annual Catch Basins inspection and sediment removal. Cleaning requires a vacuum 10% truck and/or climbina into the ætch basin. Maintenance of the storm sewer system consists of inspection, Storm Sewer cleaning, and general repairs. If a customer inspects, cleans 21% and repairs a public storm sewer on private property, the customer mav be elinible for a Storm Sewer credit. The maintenance of manholes involves biannual inspection and Manholes cleaning and repairs as needed. If a customer inspects, cleans 3% and repairs a public storm manhole on private property, the customer mav be elinible for a Manhole credit. Culverts and bridges provide conveyance for stormwater under Culverts! Bridges roads and other structures." If a customer has the expertise to 1% inspect, clean, or repair a culvert or bridge the customer may be eliGible for a Culverts/BridGes credit. If a customer has the capability to remove sediment and debris Creeks/ Streams from a creek or stream the customer may be eligible for a 1% Creeks/ Streams credit. Canitallmnrovement Proaram Capital improvement projects are projects built to improve the Future Projects infrastructure or performance of the City's Stormwater 26% (Debt Relief) Management System. Under rare circumstances a customer mav be eliGible for a CIP credit. NPDES Public Education The City will consider the maximum credit for public eduætion 4% & Outreach Public and outreach and public involvement and participation tasks. Involvement & Activities considered must be applicable to the program 4% Participation outlined in the City's NPDES Phase II permit. Direct Discharae Credit A direct discharge credit may be available for the portion of a property's impervious area that is contiguous to (or contains) and discharges stormwater directly into, the 20% Mississippi River, Catfish Creek, South Fork Catfish Creek, or Middle Fork Catfish Creek. Private Detention Basin Credit Peak Flow Credit may be available if the peak flow of runoff during 2, 10, Preservation and tOO-year rains after development does not exceed the 10% peak flow of runoff that occurred nrior to develooment. Credit may be available if a detention basin is shown to reduce Peak Flow the pre-development peak flow of runoff from the site by at 12% Reduction least twenty percent during 2, 10, and 100-year rains following develonment. Private NPDES Credit An NPDES credit may be available is available for a customer who maintains an NPDES General Permit No.1 or General Permit No.2 for stormwater discharge 10% associated with an industrial activitY. NOTE: The maximum credit per account is limited to 50% of the total billing units. 3 --- Facility and Activity Credits The City's Stormwater Management System is funded through various sources, including the Dubuque Racing Association distribution, the general fund, bonds, fees, and the Stormwater User Fee. The City allocates money from each source to activities or facilities associated with stormwater management. Customers are only allowed facility and activity credits for facilities or activities that are associated with the City's services funded by the stormwæer user fee. See Table 1 for a list of the potential facility and activity credits. Direct Discharge Credit A direct discharge credit may be available for the portion of a property's impervious area that is contiguous to (or contains) and discharges stormwater directly into, the Mississippi River, Catfish Creek, South Fork Catfish Creek, or Middle Fork Catfish Creek. Runoff that passes through a public or private drainage facility such as a detention basin, ditch, or drainage way prior to discharging into one of the receiving waters identified above is not considered direct discharge. Private Detention Basin Credit A private detention basin credit may be available to a customer that maintains a private detention (or retention) basin that reduces the impact of the stormwater drainage on downstream properties. There are two concurrent credits available: peak preservation credit and peak reduction credit. The peak flow preservation credit may be available if the peak flow of runoff during 2, 10, and 100-year rains following development does not exceed the peak flow of runoff that occurred prior to development. The peak flow reduction credit may be available if the runoff during 2, 10, and 100-year rains following development is twenty percent lower than the peak flow of runoff that occurred prior to development. A 4% credit is available for a twenty percent reduction in peak flows for each of the three rain events. In order for stormwater detention facilities to operate as designed, maintenance must be performed on a routine basis. Improperly maintained facilities fail to provide the intended stormwater management benefit. The minimum maintenance requirements for detention facilities are as follows: 1) The owner must make periodic inspections and fill out an inspection report, noting the condition of the facility; 2) The owner must remove sediment when approximately 20% of the storage volume is filled; 3) The owner must remove sediment or debris whenever it can potentially block the outlet structure; 4) The owner must keep the outlet control structure structurally sound, free from erosion, and functioning as designed; and ~ 4 Stormwater Management Utility Fee Reduction Credit Application 5) The owner must maintain the facili ty so that there is NO STANDING WATER. If a random City inspection finds that the detention basin does not operate as outlined in the credit application, the City will send a letter informing the customer of the required action to avoid revocation of the credit. If the property owner fails to take the required action, the credits will be revoked. The credit may be restored when the detention basin functions properly. Private NPDES Credit Certain private industrial operations are required to obtain an NPDES pennit from the Iowa Department of Natural Resources. The permit requires the industrial operation to implement measures to manage stormwater runoff to minimize the pollutants associated with the stormwater runoff that leaves the property. Credit Application Process The City of Dubuque Engineering Division will accept applications from customers for credits. Applications are available in the Office of the Engineering Division at City Hall. In most cases, engineering calculations are required to support credits. A registered professional engineer may be required to prepare some of the supporting application documents. To apply for a credit, the customer must submit a completed STORMWATER MANAGEMENT UTILITY FORM NO.6: APPLICATION FOR USER FEE CREDIT, along with the required documentation and applicati on review fee, to the address below: City of Dubuque, Engineering Division Attention: Deron Muehring 50 W. 13th Street Dubuque, IA 52001 Phone: (563) 589-4270 The Public Works Director will review the credit application. Upon approval of a stormwater credit, the credit will be given at the next billing. A credit may be retroactive to the beginning of the City's current Fiscal Year if it can be shown to the satisfaction of the Public Works Director that the justification for the credit was in place at that time. Annual Credit Re-Application Process To ensure that a credit remains justified, a credit application will only remain valid for one year. Customers must re-apply for the credit using UTILITY FORM NO. 6-R: RE-APPLICA TION FOR USER FEE CREDIT.
