1 Stormwater Utility Feasibility Study City of Geneva City Council Presentation: October 16, 2017

2 Stormwater Feasibility Study Overview Overview of Current Program Stormwater System Needs Stormwater Utility Concept Range of Stormwater Fees Stormwater Utility Feasibility

3 Importance of Stormwater Management Flood Control / Property Protection Maintenance of the stormwater system to protect individual and personal property Ensure roadways are accessible Water Quality Stormwater management to protect natural environment (local water ways) Regulatory Requirements The City s stormwater system discharges are subject to Clean Water Act City is required perform stormwater management activities to comply with stormwater discharge permit

4 Current Stormwater Program City currently manages a limited stormwater program No dedicated stormwater management staff / decentralized program Budgeted annual expenditures $55,000 Program is funded from sewer fee revenues A portion of sewer fee revenues are used to fund stormwater activities Program is currently reactive City completes majority of stormwater activities on an as needed basis City currently does not have a defined capital improvement plan for the stormwater system

5 Stormwater System Needs Current Level of Service Reactive and Insufficient Annual Cost: $55,000 Target Level of Service Proactive and Comprehensive Annual Cost: $445,000 Catch Basin and Sump Pump Repairs Catch Basin Cleaning Ditch and Swale Maintenance Detention Basin Maintenance Conditions Assessment Capital Improvements

6 Stormwater System Needs 1120 Fargo Blvd. Cheever Ave. and Shady Ave. Miller Road Define drainage problems Stormwater master planning Develop and prioritize projects Engineering and construction Fargo Blvd. and Rt. 31 Drainage Problems and Localized Flooding

7 Stormwater System Needs Illinois EPA Municipal Separate Storm Sewer System (MS4) Permit Compliance Stormwater Public Education and Outreach Develop and distribute stormwater quality materials Educate on green infrastructure / climate issues Public Involvement / Participation Illicit Discharge Detection and Elimination Involve public in the City s stormwater program Determine environmental justice areas Map and inspect storm drain outfalls annually Eliminate and enforce against illicit discharges Current funding level $40,000 Construction Site Storm Water Runoff Control Post-Construction Storm Water Management Pollution Prevention/Good Housekeeping Inspect stormwater compliance at construction sites Documentation, enforcement follow up Enforce post construction stormwater requirements Assess water quality impact of all drainage facilities Annual staff training on best management practices Catch basin cleaning, sweeping, material control Enhanced level $80,000

8 What is a Stormwater Utility An approach to organizing and funding stormwater management with dedicated revenues generated from user fees based on use of the stormwater system. City Utilities Service Provided Funding Approach Water Drinking Water Water Fees Sewer Wastewater Collection/Disposal Sewer Fees Solid Waste Trash Collection/Disposal Solid Waste Fees Stormwater Stormwater Management Sewer Fee Stormwater Fees

9 What are the benefits of a stormwater utility? Fair and Equitable Transparent and Accountable Dedicated Stable Funding Stormwater Utility Needs Based

10 Based on measure of stormwater contribution Measure of Stormwater Impact Source: Lowimpactdevelopment.org Increasing Impervious Surface = Increasing Runoff Generated Surface Runoff Generated 1-inch Rainfall Event One-Acre Open Meadow = 1,600 gallons One-Acre Parking Lot = 26,000 gallons

11 Approach to Assessing Stormwater Fees Fees based on impervious area on property Non-Residential Residential = (58 ERUs) (1 ERU)

12 Impervious Area Analysis Property Type Total Parcel Area (sq. ft.) Estimated Impervious Area (sq. ft.) Number of ERUs Residential 128,274,000 39,747,000 7,100 Commercial/Industrial 65,586,000 49,190,000 8,800 Institutional 8,070,000 3,356, Total 201,930,000 92,293,000 16,500 $1 stormwater fee = $16,500 in revenue

13 Range of Fees Based on Needs Operating Expenditure Type Monthly Stormwater Fees Year 1 Year 5 Year 10 Existing Operating (Replace current revenues) $0.28 $0.31 $0.36 NPDES Compliance $0.21 $0.26 $0.33 Additional Operating Costs (catch basin cleaning, ditch maintenance, condition assessments) $1.75 $1.97 $2.29 Total Operating Expenditures $2.24 $2.55 $2.98 Capital Projects Studies - $0.37 $0.10 Capital Improvements* - $0.90 $4.18 Total Capital - $1.27 $4.28 Total Fee to Fund All Needs $2.24 $3.82 $7.26 *Assumes issuance of debt to fund capital projects

14 Example Property Stormwater Fees Typical Single Family Residential Property Impervious Area (sq. ft.) 4,400 Number of ERU s 1 Monthly Stormwater Bill Year 1 $2.24 Year 5 $3.82 Year 10 $7.26

15 Example Property Stormwater Fees Typical Commercial Property Impervious Area (sq. ft.) 22,607 Number of ERU s 4 Monthly Stormwater Bill Year 1 $8.96 Year 5 $15.27 Year 10 $29.04

16 Example Property Stormwater Fees Public Works Facility Impervious Area (sq. ft.) 345,000 Number of ERU s 58 Monthly Stormwater Bill Year 1 $ Year 5 $ Year 10 $421.15

17 Illinois Stormwater Utility Comparisons Monthly Stormwater Fee Winnetka $21.83 Dow ners Grov e $10.53 Normal $9.20 Rock I sland $8.88 Highland Park $8.00 Aurora $6.90 Richton Park $6.34 Moline $5.85 Champaign $4.94 Urbana $4.94 Galesburg $4.35 Decatur $3.67 Bloomington $2.90 Hoffman Estates $1.50

18 Feasibility of Utility A stormwater utility would be a feasible option for organizing and funding the City s stormwater system As demonstrated the current program is not sufficient to meet the needs of the City stormwater system The current funding and management of the stormwater system are not sustainable over the long-term Additional dedicated funding is required and a stormwater fee would equitability provide these funds

19 Implementation Requirements To implement a stormwater utility within the City several key steps are required Given the fact that Geneva is not a home rule community, a referendum would be required to implement the fee Impervious area measurements would be required for all nonresidential parcels Adoption of ordinance establishing the fee
