CCWRA - Emergency Action Plans

The Authority owns and operates four regional flood control facilities which are classified by the Pennsylvania Department of Environmental Protection, Division of Dam Safety, as High Hazard Dams. These are dams so located as to endanger populated areas downstream by its failure.

An Emergency Action Plan has been developed for each of the four dams. A copy of the plans, including an inundation map noting areas subject to flooding in the event of failure, are available for public inspection at the office of the Chester County Water Resources Authority and the offices of the municipalites listed below.
