Body
Recommended Action:
Recommendation
Receive presentation concerning the Proposed 2025 Stormwater Non-Ad-Valorem (NAV) Assessment Rate Increase.
Body
Background:
The City of Delray Beach (City) performed a Stormwater Rate Study to assess the City's existing stormwater rate structure and provide recommendations for improvement in FY 2023. The stormwater rate study findings, recommendations and options for future rate structure and rates were presented to City Commission on April 18, 2023. On May 16, 2023, the City Commission enacted Ordinance No. 18-23 establishing a new rate structure and process for implementing the annual Stormwater Non-Ad-Valorem (NAV) Assessment.
The current SWU rate of $1.12/month or $13.44/year, approved by City Commission for the 2023 Stormwater Tax Roll, was not increased for the 2024 Stormwater Tax Roll. In 2023 and 2024 the total assessed amount for the entire City was $4,228,318.36 and $4,292,820.66 respectively. To meet the target revenue per the 2023 Stormwater Rate Study plan, the new rate of 1.93/month/SWU is needed to recover about $2,940,694.00 and place the City back on track for 2026.
Stormwater NAV assessment rates need to be increased to fund projects identified in the 2019 Stormwater Master Plan aimed at addressing impacts , flood control measures, drainage infrastructure enhancements, and maintenance compliance with evolving regulatory requirements, including the MS4 National Pollutant Discharge Elimination System (NPDES) under the Environmental Protection Agency (EPA).
The current Stormwater Billing Unit (SWU) rate is $1.12/month or $13.44/year.
