Tampa Stormwater Charges and Flood Relief

Stormwater Services in the City of Tampa Mobility Department plans, builds, operates and maintains the city drainage system, and it takes calls at 813-274-3101 from 107 North Franklin Street, Monday to Friday 7:30 a.m. to 4:30 p.m. (City of Tampa Stormwater Services).

The Tampa stormwater pages carry a Stormwater Customer Service Request form and a Report A Problem menu with separate entries for a curb, street or gutter, a ditch or retention pond, and illegal dumping. Dumping anything other than stormwater into a Tampa storm drain, or connecting an unauthorized pipe or ditch to it, is illegal, and many of those drains outfall to Tampa Bay or the Intracoastal Waterway (Stormwater Services).

Before calling about a blocked inlet, it is worth checking whether a crew is already assigned. The city publishes interactive dashboards of open and completed stormwater work orders, where each dot is a job with its type and completion date, and the map can be filtered by work order type and City Council district (Stormwater Services dashboards).

The city's Hurricane Stormwater Information Hub holds the briefing slides from a Forest Hills community meeting held October 15, 2024, water level graphs for the Eastridge and Robles pump stations, separate Alline pump station notes for Milton and for Helene, and a supervisor's check of the Curiosity Creek pump station at 3 p.m. on October 11, 2024. The hub was last updated July 16, 2026, yet both of its dated items are from October 2024 (Hurricane Stormwater Information Hub).

Tampa charges $82.00 per Equivalent Stormwater Unit for the Service Assessment and, inside the Central and Lower Basin Improvement Area, another $89.55 per unit for the Improvement Assessment (City of Tampa, 2026 assessment information).

Computed from those two rates, a 1.00 ESU medium single-family home in that area owes $171.55 a year. One ESU stands for 3,310 square feet of impervious surface, the city's figure for the median single-family dwelling: a 1,667-square-foot footprint plus 1,643 square feet of other impervious area on the parcel. Single-family homes are not measured one by one; with more than 80,000 single-family parcels, Tampa sorts them into tiers by gross building area (2026 assessment information).

Tiers, unit values and rates come from the City of Tampa 2026 stormwater assessment information; the dollar columns are computed here from the city's rates (ESU times rate, rounded to the cent) and do not appear in the city document. Multi-family parcels with Property Appraiser DOR code 08, no more than two buildings and no more than four units per building use tiers of 0.44, 1.01 and 2.25 ESU, and every other parcel is charged by its measured impervious area divided by 3,310.

Both Tampa charges cover the city fiscal year from October 1 to September 30 and ride on the property tax bill, so an owner whose mortgage holder escrows property taxes may be paying them inside the monthly mortgage payment. Tax-exempt properties still pay, and government-owned properties are billed directly. The city estimates the Service Assessment brings in $15.9 million a year; the Improvement Assessment, first billed in November 2016, raised an estimated $15.5 million in FY 2025 and is scheduled to end in 2045. Owners who want installments arrange them with the Hillsborough County Tax Collector at (813) 635-5200 (2026 assessment information).

The two Tampa charges pay for different work. Upkeep of the existing system, from sweeping streets and clearing pipelines and outfalls to keeping ponds and ditches working, is the job of the older charge, which Resolution 2003-937 set up in 2003. Resolution 2016-706 added the second charge in 2016 for capital work in the Central and Lower Basin, such as new pipelines and box culverts, pump stations, backflow valves, inlets and curb and gutter systems (Stormwater Assessment Program).

Yes: Tampa grants mitigation credits of 10% to 100% for properties that handle their own runoff, and a Stormwater Hardship Program pays the Improvement Assessment for qualifying elderly, disabled and disabled veteran homeowners (2026 assessment information).

The credit schedule is set out by the city. A parcel with no offsite discharge to the Tampa system gets 100%. An owner who runs a stormwater facility sized for the 50-year storm gets 40%. Contributing money to a Community Development District, homeowners or property owners association, or special district that maintains non-city stormwater facilities taking drainage from city right-of-way earns at least 10%, as does a working onsite system that treats or holds water before it leaves the lot. A credit applies to both assessments (2026 assessment information). The policy behind it was adopted February 1, 2018, by Resolution 2018-94 (Stormwater Mitigation Program).

Owners who think their parcel was put in the wrong tier have a short window. A written petition to review the ESUs assigned to a Tampa tax parcel must reach the director within 30 days of the assessment notice, and the city reviews it within 30 days of filing (2026 assessment information).

The Tampa Stormwater Hardship Program, created under Resolution 2016-706, has strict limits. At least one owner must be 65 as of January 1, unable to work because of a disability, or a veteran with a service-connected disability; household income may not exceed 30% of Area Median Income; and the home must be a homesteaded, owner-occupied single-family property with a taxable value of less than $100,000 after exemptions and an assessment of 1.0 ESU or less. Housing and Community Development handles applications at 813-274-7940 (Stormwater Hardship Program). That page was last updated October 1, 2023, and the 2026 assessment sheet lists a different number for the same division, (813) 274-7957 (2026 assessment information).

Tampa credits on non-residential parcels do not last forever. Condominiums, multi-family homes, apartments and general parcels with a mitigation credit must recertify every five years from the date it was applied, while single-family homes keep theirs without recertifying; the Stormwater Assessment team answers at (813) 274-8386 (Stormwater Mitigation Program).

The July 2026 Tampa stormwater report lists Southeast Seminole Heights finishing in fall 2026, the Lower Peninsula project completed in March 2026, and Golf View Estates and South Howard both due to start construction in spring 2027 (City of Tampa quarterly report, July 2026).

All rows come from the July 2026 Stormwater Capital Improvements Quarterly Report, which notes that cost and schedule figures are Tampa's current best estimates and subject to change. The Southeast Seminole Heights work covers about 16,300 linear feet of culverts plus about 11,700 feet of replacement water mains, with cooperative funding from the Southwest Florida Water Management District.

Golfview's problem, as the report describes it, is an old and undersized drainage system that can leave low-lying streets taking days to drain after high intensity, short duration rain; the new pipes will tie into the Dale Mabry Henderson Trunkline at West Watrous Avenue and South Dale Mabry Highway. South Howard Avenue will also get wider sidewalks, relocated TECO power lines and drainage for the expanded South Selmon Expressway in partnership with the Tampa Hillsborough Expressway Authority (July 2026 report).

A smaller Tampa fix sits off the big list. Flooding at Franklin St. and Henderson Ave. happens because the existing inlets have no positive outfall, and the city project ties new inlets and pipes into the Estelle St system for discharge to the river (Franklin: Henderson to Estelle).

Tampa hands out sandbags only after an emergency declaration, and every property owner in the city may receive ten per storm event at whichever distribution sites the city activates (City of Tampa sandbag policy).

Residents must show identification proving they live inside Tampa city limits, such as a valid driver's license, a utility bill or an electric bill. A pre-registration program takes less than five minutes and notifies the resident by email or text when and where to collect the bags. The page sends readers to the city newsroom and the @AlertTampa account for each storm's active Tampa sites (Sandbag Pickup).

The same Tampa page reports a city test of sandbag alternatives against two feet of water at a residential door. Sandbags gave the least protection from water intrusion, and an expanding urethane foam sealant gave the best result in limited, short-term flooding; the other materials tested were visqueen backing, duct tape and caulks (Sandbag Pickup).
