From the Public Works Department: Stormwater Best Management Practices


All paints, solvents, and adhesives contain chemicals that are harmful to wildlife and humans. That is why the proper handling and disposal of these products is important. Toxic chemicals from liquid, solid products, cleaning residues or rags may enter waterways via the storm system. It is especially important not to clean brushes in an area where these contaminants are exposed to the weather and could be washed into the storm system during a rain event. As a contractor, site supervisor, owner, or operator of a site, you may be held responsible for the environmental damage caused by your subcontractors or employees

Automotive Maintenance and Car Care

Many common car maintenance routines contribute to water pollution. Power washing engine blocks or pouring used motor oil into storm drains pollutes our waterways. These pollutants cause harm to plant and aquatic life. Oil and grease can clog fish gills and block oxygen from entering the water. If oxygen levels get too low, aquatic animals die.

Concrete and Mortar Application

Fresh concrete and mortar activities are frequent sources of stormwater runoff pollution. Materials and waste from these operations that are blown or washed into a street, gutter or storm drain eventually enter the City storm system which drains to the St Lucie River. These sediments washed from work sites create multiple problems, clogging fish gills, and blocking light transmission for plant growth thus harming aquatic life.

Landscape and Garden Maintenance

Soils, yard waste, and garden chemicals are pollutants that can wind up in the storm system and then enter Florida’s waterways after a rain event. Fertilizers and pesticides can poison fish and contaminate groundwater and surface water. Yard waste when it decomposes will absorb oxygen that fish need to survive.

Know Your Stormwater Flow

If you operate a business, chances are that you’re contributing to stormwater runoff pollution and not even know it. Any item that is spilled or dumped on the ground, whether it is litter, oil, soapy water, yard waste, food products or paint will be washed downstream in the next rain event. This runoff pollution is not treated, and will eventually drain into our river, estuary and ocean. These pollutants can cause damage and even death to plant and aquatic life, and contaminant ground and surface waters.

The Solution to Stormwater Pollution

As stormwater flows over driveways and lawns it picks up pollutants and deposits them in the storm system, causing damage to the environment.

Save the Swales

Swales store and clean stormwater by giving it a chance to absorb back into the ground instead of running off into surface waters.

BMPs for Food Service

The by-products of food-related businesses can harm Florida's waterways and aquatic life if they enter the storm drain.

Pet Waste

When rain washes pet waste into swales or stormwater drains, pollutants are carried along to water bodies. These pollutants include nutrients and bacteria.

Grass Clippings (English and Spanish)

Grass clippings and other yard waste are considered a source of pollution. When these materials decompose, they release nutrients.

Personal Pointless Pollution

Stormwater runoff pollution is a major contributor to the degradation of our local waterways.

Fertilizer Management

Fertilizers can contribute to nutrient pollution in our waterways. There are several requirements and restrictions for applying fertilizer to your lawn.
