The City provides service, maintenance, and improvements to existing stormwater facilities and infrastructure (such as piping, retention areas, outfalls, pump stations, and Best Management Practice tools) with the use of City equipment, vehicles, and personnel, as well as external contractors and consultants. Part of the Capital Improvement Program allows for large scale projects to the stormwater system that are aimed at short and long-term reductions to flooding and runoff, improvements in water quality to receiving water bodies, and protection against sea level rise. Some examples of current projects being funded under this program are the Lakes Restoration and Improvement Project, the Beach Outfall Removal Project, and the City Basin Assessments. The City also upholds important ordinances and maintains compliance for permits, such as the federally mandated National Pollutant Discharge Elimination System (NPDES) permit that is required to discharge stormwater runoff to natural water bodies and provides water quality monitoring.
Services include maintaining existing stormwater facilities to avoid drainage problems (such as lakes that receive public drainage, swales, ditches, and pipes), building new runoff controls to improve water quality and reduce flooding, and reviewing new development for compliance with City standards.
The current stormwater fee structure was developed in a 1990 study and is not representative of current parcel characteristics because it uses a flat fee for single-family residential parcels. Analysis in this study found that there are significant differences and a wide distribution of impervious area found on single-family residential parcels throughout the City. Impervious area is defined in the City’s Ordinance as roofed or paved areas, including but not limited to areas covered by roofs, roof extensions, patios, porches, driveways, sidewalks, nonporous parking areas and nonporous athletic courts. There is more current data available for parcel impervious area from the Collier County Property Appraiser, which was used to develop the fees in this study. This study seeks to modernize the current fee structure in a way that is sensitive to the unique parcel characteristics in the City and comports with industry best practices.
The fee structure would change from billing on an average residential unit (ARU) to a more common industry approach based on an average single-family residential unit (SFU) in the community. The SFU is characteristic to the conditions in Naples and is the average impervious area of your City’s single-family residential parcels, which is 4,825 square feet.
The current flat fee being charged for single-family residential is proposed to be changed to a tiered fee system based on impervious area for each parcel found on the Collier County Property Appraiser’s website. The tiers were developed using the statistical distribution of impervious area across all single-family residential parcels with breakpoints roughly at 30, 60 and 90%.
Tier 1 lies between 0 and 3,200 square feet of impervious area, Tier 2 lies between 3,201 and 6,400 square feet, Tier 3 lies between 6,401 and 9,600 square feet, and Tier 4 is for single-family residential with more than 9,601 square feet of impervious area. Tiers 1, 2, and 3 are a specific fee and the Tier 4 fee will be unique for each parcel, determined by the measured impervious area.
Non-residential will have a unique fee for each parcel determined by the measured impervious area in the City’s database.
The last significant fee increase was in 2008. With system costs increasing since this time, the current fee will not fund the Department’s anticipated needs starting in Fiscal Year 2023 (beginning October 1, 2022) and, due to the extensive funding demands for master planning and Capital Improvement Projects to address flooding, sea level rise and water quality projects, the fund balance will be depleted for capital improvement projects in less than one year from now.
Based on the revenue requirements identified by the City, Stantec performed a revenue sufficiency analysis to determine a sustainable financial plan. The monthly fees were calculated for Fiscal Year 2023 (beginning October 1, 2022) and Fiscal Year 2024 (beginning October 1, 2023), followed by inflationary increases of approximately 4% thereafter.
