What is a BMAP?
BMAP is an acronym for Basin Management Action Plan. A large part of Deltona is located in a Basin that falls under a Florida BMAP. What this means to the City of Deltona is that we must take ‘Action’ to improve the quality of water that flows from our Basins and enters into Waters of the State.
A basin is the area of land where the water sheds down to a low lying surface water body (see image1). We all live in watersheds, and groups of watersheds make up basins.
Deltona has basins that discharge to Lake Monroe. Lake Monroe and the Middle St Johns River are impaired because of too much nutrients (nitrogen & phosphorus).
Since our basin has historically contributed to the nutrient load of these waterbodies, Deltona falls under this BMAP, along with many of the neighboring municipalities that discharge to St Johns. This means we all need to take action to return the surface water’s health and original designated use.
The City of Deltona has taken some major steps already to meet the goals set forth in the action plan. We have installed systems that will remove these pollutants prior to discharge. The new stormwater ponds that you may see throughout the city are doing just that; they function by allowing the water to sit; meanwhile, heavy metals and nutrients are moving toward the bottom as clean water is let go on the surface. Audubon Park is another example of a “Treatment Train”; each pond (see image2) serves a purpose to remove pollutants in a row. It also serves as habitat for a variety of species of plants, birds, and animals. City personnel also help by maintaining the stormwater infrastructure, routine cleaning of catch-basins and regular swale maintenance all reduce flooding, which means less pollutants flowing in surface waters.
What we all really need to understand for our individual part in all this is that Lake Monroe & St Johns River are not as healthy as they should be because of nutrients like nitrogen & phosphorus. We can all help return them to health by:
*applying fertilizer only when necessary using the appropriate type & amount, and not before a
big rain that can wash it away or leech it down into the aquifer.
*maintaining our septic systems to prevent the impacts from improperly functioning systems.
*discarding of our pet’s waste into the general trash for disposal in a lined landfill.
These are all sources of nutrient pollution which has impaired the natural state of our waters.
