POST PEAK DISCHARGE Basic Concept: · Problem: Developing land causes more stormwater to runoff faster, increasing "peak" runoff. · Bad news for downstream neighbors. · Solution: Regulations say development cannot increase peak runoff. Developments must hold back water in lakes and release it slowly through control structures. · Good news for downstream neighbors...sort of. · In theory, current regulations prevent offsite impacts. · In reality, they prevent faster runoff, but don't solve the problem of more runoff, nor cumulative impacts.

FU'I'URE CHALLENGES (Potential Liabilities) As our community matures over the long term and Homeowner Associations become less effective, the proper maintenance of development detention/retention lakes may have to be assumed by the County. (So said the nationally known expert who helped prepare our 1989 Master Plan). The detention/retention lakes that function as water quality treatment areas are slowly accumulating pollutants in their bottom sediments. Over the long-term, removal of these potentially "hazardous waste" materials will be a very expensive proposition.
