Vero Beach Stormwater and the Lagoon

Rain that falls inside Vero Beach city limits is the job of the Stormwater and Drainage Division of the city Public Works Department, and most of it ends up in the Indian River Lagoon.

The Stormwater and Drainage Division page states the division's mission as building, maintaining and improving storm sewers, drainage ditches, drainage swales and drainage structures, and providing construction services for the city's sidewalk improvement and repair program. Reports of storm drain pollution go to the Public Works and Engineering Department at City Hall, 1053 20th Place, Vero Beach.

The Vero Beach division page describes stormwater as rain that flows off streets, rooftops and lawns, carrying sand, soil, pesticides, fertilizers, leaves, grass clippings, oil and litter, and notes that it is not clean and usually receives no treatment. It singles out three kinds of pollutants: sediment that clouds the water, phosphorus that fuels the growth of algae and aquatic weeds, and toxic chemicals such as motor oil, lead, and zinc from roof drains and tires. For Vero Beach households it recommends keeping pesticides, oil and leaves out of storm drains, diverting roof runoff to lawns or gardens where it can soak in, repairing car leaks, and picking up after dogs, since animal waste adds harmful bacteria to local waters.

The city's February 2024 Stormwater Management Plan maps where that water goes. It describes Vero Beach as approximately 13.5 square miles in Indian River County, says most city stormwater discharges directly to the lagoon, and notes that most of the western side of the city outfalls through the Main Relief Canal on the northern edge of the city, with the Lateral E Ditch as a notable secondary canal and a small portion of the city draining to the Atlantic Ocean.

The Vero Beach case for a stormwater utility rests on a Public Works presentation and two 2016 reports posted on its Stormwater Utility Report page.

The Vero Beach Stormwater Utility Report page lists a City Stormwater Background presentation, a Preliminary Report dated January 22, 2016, and a Stormwater Utility Preliminary Evaluation Presentation dated February 21, 2016. The background presentation, prepared by Public Works, sets out the core drainage network: 77 miles of pipe, 43 miles of ditches and 6,000 drainage structures, with a replacement cost of $25 million in total, or $500,000 a year for a 50-year design life. It notes that these costs cover moving water for flood protection and do not include treatment of runoff.

The presentation also gives a stormwater timeline for Vero Beach: the Indian River Farms Water Control District created in 1919, the city incorporated in 1925, the Clean Water Act and state drainage districts in 1972, city stormwater rules in 1988, a TMDL issued in 2009, updated city codes in 2010, a superbloom event in 2011, and Basin Management Action Plan cycles in 2013 and 2018. Its funding summary lists a stormwater utility among the possible revenue sources for both repair and restoration work and lagoon treatment.

Before a dedicated fee was proposed, Vero Beach paid for stormwater capital work mainly from sales tax revenue and grants, according to the background presentation.

The presentation's table of the Vero Beach 304 Capital Fund for the five fiscal years 2011 through 2015 shows how the money split between repair and replacement of the drainage system and treatment of runoff.

Across those five years treatment took 37 percent of Vero Beach stormwater capital spending, an average of $189,800 a year. The presentation's funding goals proposed raising both repair and restoration and lagoon treatment to $500,000 a year each, while keeping about $700,000 a year in general fund tax revenue for the manpower and equipment that maintain the system. Rate decisions made after that study are not covered by the city pages reviewed here.

The city's model project is the 2010 Humiston Park stormwater project, which both moves and treats runoff from Ocean Drive.

According to the background presentation, two relatively small pumps once drained Ocean Drive, and the beach recorded 21 closures for excessive E. coli bacteria from 2001 to 2009. After the 2010 project added a new high-capacity pump and treatment, the presentation reports no beach closures and a 90 percent reduction in discharge to the ocean. The $577,000 project was paid 42 percent by the City of Vero Beach, $241,000, and 58 percent by EPA and FDEP grants, $336,000.

Treatment coverage was the larger gap. The presentation said 34 percent of the city's urban area had some form of stormwater treatment, that $2.3 million in proposed projects over five years would raise coverage to 53 percent, and that another $1.1 million would bring it to 64 percent, with the rest of the city low priority or impractical to treat. The city's Clean Lagoon page adds the household side of the work: never drain used motor oil into storm drains, because it goes directly to the Indian River Lagoon, and do not apply lawn chemicals when rain is in the forecast.

The February 2024 Stormwater Management Plan, prepared for the city by Kimley-Horn and Associates, is the current Vero Beach road map for lagoon projects.

The plan's primary goal was to identify projects that treat runoff to improve water quality, with flood relief as a secondary goal. It weighed bioswales, catch basin inlet filters, constructed wetlands, floating littoral mats, hydrologic restoration, outfall filters such as nutrient separating baffle boxes, rain gardens, stormwater chambers and wet detention ponds. The study identified 12 regional projects, 10 neighborhood projects and 3 local projects, plus 5 pilot demonstration and education projects, and recommended a regional treatment facility at the intersection of 5th Avenue and Indian River Boulevard as the most cost-effective for nitrogen removal. The division page also lists a Vulnerability Assessment Final Report dated February 2025.

The plan sorts Vero Beach projects by scale. Regional projects treat catchments of more than 100 acres, often by routing major pipes or canals to a new treatment site; neighborhood projects treat 10 to 100 acres; and local projects treat less than 10 acres from a single site. Cost estimates drew on the Florida Department of Transportation basis of estimate and included land, design, construction, maintenance and project lifespan. The plan notes that its scope is limited to the city limits, and suggests the city consider partnerships outside those limits, where more land at lower prices could make larger projects more cost efficient.

The Vero Beach Watershed page frames the problem in numbers: a one-acre parking lot produces 16 times more stormwater runoff than a one-acre meadow, a single quart of motor oil dumped down a storm sewer creates a two-acre oil slick, and 27,200 gallons of water fall on a one-acre yard during a one-inch rainfall. The page also says a properly operating septic system discharges an average of 10 pounds of nitrogen to ground water per user each year, and that research finds urban stream quality declines sharply once impervious cover in a watershed, such as streets, driveways, sidewalks and rooftops, exceeds 10 percent.

For partners, the city's Indian River Lagoon Conservation page calls the lagoon the most biologically diverse estuary in North America and points to the Ocean Research and Conservation Association, founded in 2005; the Marine Resources Council, whose executive director presented on fertilization at the October 18, 2011 Vero Beach City Council meeting; and the Environmental Learning Center, whose stated mission is environmental education that inspires participants to be active stewards of the surrounding natural resources. The Clean Lagoon page names the everyday sources it calls pointless personal pollution: nutrients and bacteria leaking from septic tanks, pesticides and fertilizers, sand and dirt from erosion, oil and grease from cars, and litter, yard clippings and pet waste.
