Hayes was demonstrating Friday how much the narrow stormwater detention pond behind his house in the Galvez area of Ascension Parish had filled in with sediment since it was built more than a decade ago.

Bingo.
Also, the actual construction, as in when they build them, is another concern. A lot of times they get silted in before construction of the neighborhood is even complete because of non-existent SWPPP enforcement.

I can get on board that this is a common problem. If it is then Developers need to properly account for it in their HOA dues and budgets prior to turning it all over to the homeowners who have zero clue what they are inheriting.

You're wrong, though. The ponds are only designed to manage between a 4% and 10% annual probability event. Beyond that, they absolutely allow the development to increase discharge into our streams. We've seen 2 events under 0.2% annual probability in the last 5 years. We see multiple 1% events each year. Until Atlas 14 is updated in about a year, we're going to see that the design storms are pretty grossly underestimated.
We are rapidly altering the hydrology of the parish with all the development. Unfortunately, the developers are going to push back hard against the needed reforms, and capitalism will defeat common sense once again.

Wrong. If a pond stays 80% full of water or mud, there's only 20% left to fill during a storm. 20% is 20% no matter what you fill it with.
