Specifications include, but are not limited to: At the upstream end of the project, the degraded rock headwall will be removed and replaced. As a safety precaution, black-vinyl chain link fence will be installed on top of the proposed headwall. An imbricated wall will be installed along the near bank to protect the exposed sanitary sewer manhole. A second imbricated wall will be installed along the far bank to stabilize the eroded channel. A split-rail fence will be installed along the top of the near bank wall, and from the headwall to the property line and out to Roxboro Road, to discourage trespassing. To protect public infrastructure, a modified concrete encasement will be installed around the exposed sanitary sewer line. To alleviate existing drainage issues at the park entrance, the existing curb-and-gutter along Roxboro Road will be extended to convey runoff to an inlet to be installed with a pipe that outfalls into the channel.
