Whetstone Run Stormwater Ponds Management Project (Phase II)


As a part of the County's effort to protect our waters, five  stormwater ponds within the Whetstone Run Watershed were selected for restoration to help reduce stormwater pollution draining into our streams.  Two of the five stormwaterponds are included in phase II of the project. The other three stormwater ponds are part of phase 1 and have been constructed. 

Various public events were held throughout the project phases for residents to learn about the project and to provide input on the design of the project. Public events and project schedules may vary by site.
