I got a 6 acre parcel that will be developed into 6 lots and that will discharge directly into a floodplain with no structures directly downstream between the discharge point and the floodplain , however a 2.5 acre lake is contained within that floodplain and is directly downstream from the site. I know requirements strictly depend on each municipality, however what if I am able to provide a downstream analysis to determine that the peak flows and the peak flow timing are not contributing to any downstream flooding to justify no need for detention. What studies /analysis should be done if any to the lake directly downstream. Any guidance will be greatly appreciated.
