WAYNESBORO, Pa. - An official with the nonprofit Center for Watershed Protection on Wednesday encouraged the Washington Township (Pa.) Supervisors to continue their efforts to adopt conservation by design and flood plain ordinances as he detailed the quality of the east branch of the Antietam Creek.
"In general, it's a relatively undeveloped watershed. ... This watershed is generally in good condition," Paul Sturm said.
He described the efforts of the Antietam Watershed Association and Chesapeake Bay Foundation to develop a comprehensive report of the watershed's condition and ways to protect it in the future.
Provisions in the township govern the volume, temperature and speed of stormwater runoff in new developments, according to Township Manager Mike Christopher.
"There's been a lot of activity over the years to improve the quality of our streams," Christopher said.
Development creates impervious areas like parking lots that increase runoff seven-fold, Sturm said.
"Pollutants build up on impervious surfaces, and then they all flow into the creeks. As we pave over and pave over a watershed, you tend to see a real loss of the critters that live there," Sturm said.
