It may be time to evaluate how much sediment has accumulated in those ponds and whether or not it is time to dredge them to remove the accumulated sediment. Most municipalities and older developments own wet retention ponds that were built in the early 2000’s. The pollutants and sediment settle to the bottom of the wet pond where they often remain until they are removed.
