Excess nitrogen and phosphorus pollute our local waterways. These nutrients cause harmful algae blooms that can turn our river green, raise its toxicity, and lower the oxygen levels possibly leading to fish kills. The treatment to remove these nutrients costs taxpayers millions of dollars each year. Fertilizer and landscape debris are nutrient sources that you can control to prevent these occurrences.
Improper use of fertilizer and poor landscape practices can allow nutrient pollution to leach into ground water, or wash into the storm drainage system that eventually flows to the North Fork of the St. Lucie River and the St. Lucie Estuary, one of the most diverse estuaries in the world.
To address these issues, on March 24, 2014, the City of Port St. Lucie City Council approved a more stringent fertilizer ordinance regulating landscape practices and uses of fertilizers containing nitrogen and phosphorus.
How does the new fertilizer ordinance affect you?
It’s important to know the new regulations; since they will help to reduce harmful nutrients (nitrogen and phosphorus) found in fertilizers and yard waste, from polluting our waterways.
