The existing 15-inch corrugated metal pipe (CMP) was built to convey stream flows when the ravine was filled to construct Ash Street. Over the years, the CMP has experienced severe corrosion (rusting away) and is in jeopardy of collapsing. Pipe replacement work will involve channel stabilization within the natural resource, street closure during construction and easements to operate on private property.
