Stormwater and lagoon protection — Palm Bay, Florida

Most rain that falls on Palm Bay is collected in streets and catch basins and flows untreated into Turkey Creek or straight into the Indian River Lagoon.

The City of Palm Bay Public Works stormwater page states that Palm Bay sits inside the Indian River Lagoon Watershed and that the majority of its water reaches the lagoon through Turkey Creek or via direct discharge (City of Palm Bay Stormwater). The same page explains why that matters: runoff picks up debris, chemicals and sediment from Palm Bay streets, parking lots and roofs, and storm drains were designed to collect only rain and clean water runoff.

The legal frame is a federal permit. Palm Bay holds a National Pollutant Discharge Elimination System (NPDES) Phase II Municipal Separate Storm Sewer System (MS4) permit, which the Florida Department of Environmental Protection (FDEP) administers in Florida under authority it received from the EPA in October 2000 (City of Palm Bay Stormwater). Chapter 204 of the Palm Bay Code, passed as Ordinance 2024-42 on September 19, 2024, lists the regulatory mandates and programs Palm Bay stormwater management must meet, including the FDEP permit to operate an MS4, city-wide water quality monitoring, public outreach, the Illicit Discharge Ordinance (Chapter 95, Ordinance No. 2008-37), and management of Turkey Creek and the lagoon, including dredging and debris removal (Palm Bay Code Chapter 204). The fee itself, its ERU rate and its credits are a separate subject on the Palm Bay stormwater utility fee page.

FDEP's April 2025 draft Central Indian River Lagoon Basin Management Action Plan assigns the City of Palm Bay a required reduction of 111,991 pounds of nitrogen and 17,320 pounds of phosphorus a year, the largest of any city in that plan.

A Basin Management Action Plan, or BMAP, is the state's enforceable cleanup plan for a polluted water body. The City of Palm Bay's own January 18, 2024 council presentation explains that the lagoon's Total Maximum Daily Load (TMDL) was established by FDEP in March 2009, with a deadline of 2035 for achieving load reductions (Palm Bay BMAP presentation, page 4). Palm Bay's share is split across two FDEP project zones: 110,334 pounds of nitrogen in Project Zone A and 1,657 pounds in Project Zone SEB (FDEP draft Central IRL BMAP, Table 16).

Phosphorus follows the same pattern, with 17,041 pounds of Palm Bay's 17,320 pound phosphorus target falling in Project Zone A (FDEP draft Central IRL BMAP, Table 17). Growth adds pressure on top of the target. FDEP's Table 23 projects 17,370 additional Palm Bay residents by 2040 and estimates the extra nitrogen they would bring at 9,803 pounds a year under the best-case scenario and 40,358 pounds under the status quo scenario (FDEP draft Central IRL BMAP, Table 23). Both figures are the highest for any local government in the table.

The draft BMAP lists City of Palm Bay projects numbered PB-01 through PB-50, including Boundary Canal retention, the Basin 3 Main Street treatment train, Turkey Creek baffle boxes finished in 2024 and six more lagoon baffle boxes planned for 2026.

Among structures Palm Bay built itself, the largest measured credit belongs to Boundary Canal Phase II, an on-line retention project completed in 2014 that FDEP credits with 3,276 pounds of nitrogen and 383 pounds of phosphorus a year (FDEP draft Central IRL BMAP, page 90). The biggest credit of all goes to Palm Bay's education program, which FDEP lists as FYN, ordinances, pamphlets, PSAs, the website and the illicit discharge program, credited at 12,343 pounds of nitrogen and 1,787 pounds of phosphorus (FDEP draft Central IRL BMAP, page 91).

The Goode Park project installed nutrient separating baffle boxes at two Palm Bay drainage outfalls and is listed at $588,000; the City Marina system, a baffle box with modular wetlands and an upward filter, is listed at $890,050, and a second-generation Norwood Baffle Box Retrofit is planned for 2028 (FDEP draft Central IRL BMAP, page 92). The 22PW10 Turkey Creek Baffle Box Treatment Train, completed in 2024 at $1,500,000, put nutrient separating baffle boxes at five Palm Bay outfalls serving basins 3, 6 and 7, and the IRL 6 Baffle Boxes project ($1,500,000) and a $1,800,000 Robert J Conlan Pond retrofit are both planned for 2026 (FDEP draft Central IRL BMAP, page 94). Older Turkey Creek work also appears: maintenance dredging completed in 2007 is listed at $255,241 (FDEP draft Central IRL BMAP, page 91). Current culvert and pond schedules are tracked on the Palm Bay drainage improvement projects page.

Palm Bay takes illicit discharge reports on the Public Works Hotline at (321) 952-3438 during the day, through Non-Emergency Police at (321) 952-3456 after hours, or by the city online form, and callers may stay anonymous.

The Palm Bay Report Illicit Discharge page uses the federal definition: any discharge to an MS4 that is not composed entirely of stormwater (Palm Bay Report Illicit Discharge). It sorts them into three kinds. A transitory discharge is a one-time spill, dump or leak; an intermittent one recurs for hours a day or days a year; a continuous one comes from an illegal connection, a sanitary sewer link or a failing septic system, and the city calls that last kind the easiest to trace and potentially the largest pollutant load.

The signs Palm Bay asks residents to report are unusual color or cloudiness, a strong pungent or musty odor, floating debris, surface scum or foam, an oil sheen and algae (Palm Bay Report Illicit Discharge). The city's printed illicit discharge brochure gives a different number, Customer Service at 321-952-3437, and directs reports to Public Works at 1050 Malabar Rd SW (Palm Bay illicit discharge brochure); the Palm Bay stormwater page also lists 321-952-3437 as the Public Works number.

Enforcement sits in the city code. Under Sections 95.20 to 95.99, a responsible party may receive a Notice of Violation, be fined for administrative, inspection and remediation costs, and be required to put Best Management Practices in place at its own expense (Palm Bay illicit discharge brochure). The brochure's examples include septic tank effluent, car wash waste water, laundry waste water and leaves and grass clippings (Palm Bay illicit discharge brochure, page 2). Last verified: October 12, 2026, on the City of Palm Bay Public Works stormwater and illicit discharge pages.

Palm Bay's Fertilizer Ordinance 2014-16 bans nitrogen and phosphorus fertilizer on lawns from June 1 to September 30 and keeps all fertilizer at least 10 feet from ponds, canals, ditches, creeks and the river.

The rainy-season window exists because afternoon thundershowers can wash fertilizer into storm drains and groundwater that carry it toward the Indian River Lagoon, where it can feed algae blooms that shade out seagrass (City of Palm Bay Stormwater). Outside that window, the Palm Bay ordinance allows no phosphorus without a soil or tissue test showing a need, and any nitrogen product must be at least 50 percent slow release. A label such as 0-0-27 carries no nitrogen or phosphorus and may be used in summer, except in the 10-foot buffer. Lawn professionals need Green Industry Best Management Practice certification, and the ordinance gives two warnings before fines.

Household rules come from the same Palm Bay Public Works program. A pool should not be drained unless a test kit shows zero chlorine, and never into the storm sewer, a canal or a waterway (Palm Bay illicit discharge brochure). The Report Illicit Discharge page asks that washing machines drain to the sanitary sewer rather than a Palm Bay yard or ditch, that cars be washed on grass or at a commercial car wash, and that paint, solvents and used oil go to the County Hazardous Waste Facility (Palm Bay Report Illicit Discharge).

Palm Bay's 2024 BMAP remediation plan counts 27,780 septic systems in the city and prices the full fix, from sewer connections to septic upgrades and a treatment plant upgrade, at $665 million.

The City of Palm Bay presentation to City Council on January 18, 2024 found that only 729 of those 27,780 systems were the enhanced nutrient-reducing type (Palm Bay BMAP presentation, page 8). It identified 3,333 homes for septic-to-sewer conversion at an estimated $150 million, including 1,066 connections in Port Malabar Units 7, 8, 9 and 13 (ongoing) and 99 in a Turkey Creek area labeled as a Brevard County SOIRL area, with design to start (Palm Bay BMAP presentation, page 10). The remaining 23,718 systems would need upgrades estimated at $500 million (Palm Bay BMAP presentation, page 11).

Treatment plants are part of the same Palm Bay plan. The North Regional Water Reclamation Facility was upgraded to nutrient removal in 2022 with $3.6 million from the Brevard County SOIRL lagoon program (Palm Bay BMAP presentation, page 13), and the plan's total, including $15 million for a wastewater plant upgrade, is $665 million (Palm Bay BMAP presentation, page 15).

State law sets the deadline for Palm Bay owners. Under section 373.469, Florida Statutes, any home or business with an existing septic system inside the Central Indian River Lagoon BMAP area must connect to central sewer if available, or upgrade to a system achieving at least 65 percent nitrogen reduction, by July 1, 2030 (Florida Statutes 373.469). Connection steps and fees are covered on the Palm Bay page on connecting to city water and sewer.
