The Stormwater Master Plan (1996) and Watershed Management Plan (2001) were updated and combined into a comprehensive Stormwater Master Plan, adopted by the County Board on Sept. 20, 2014. The Plan contains information on the condition of the County’s stormwater management systems, streams and watersheds in addition to recommendations for improvements.


The following projects identified in the Stormwater Master Plan have either been completed, or are currently under construction. Additional projects will be selected for implementation from the list of high-priority projects in the Plan or as a result of newly identified needs as resources are available.
