Ornamental fertilizer is "low hanging fruit" on the scale of difficulty for remedies for water quality problems. Reconstructing mangrove swamps to replace that which is now canals and houses isn't going to happen. Getting everybody hooked up to a wastewater system so that nutrients are removed from household wash and toilet water is hard and expensive. And so on.

Of course, restricting fertilizer potentially impacts lawn management companies and that is big business around here. They don't want to hear it. It is definitely costing me personal time and money at the house we bought two years ago. I am slowly converting away from St. Augustine grass to something that won't turn yellow by July 4 up on this sand dune that I live on in Rockledge. Previous owners had no landscaping, just 0.4 acres of a type of grass that gets really mad if you don't feed it during the wet season.

There are Basin Management Action Plans for the central and north IRL and the BRL. They are fairly comprehensive. If you noticed your water bill having an extra "stormwater assessment fee" tacked on it last year that was mandated by the BMAPs to raise money for better stormwater management.

There is a page on the DEP website with links to all of the BMAPs in the state. They are long and boring but they lay out estimates of sources of water qualtiy problems and cost to fix them. There are also progress reports that summarize activities toward achieving the action items in the plans.
