Town of Knightdale

Project Types:

Service Leveraged:

Civil Engineering

McAdams was retained by the Town of Knightdale to design an alternative drainage system for the existing rip-rap channels that currently convey offsite stormwater through the site. In addition to replacement of the channels, the scope of the project included revisions to the existing drainage system around the tennis courts within the park to correct deficiencies that currently exist. McAdams obtained concurrence from the Corps of Engineers and NC Division of Water Resources; no permitting was required (wetland, stream, or riparian buffer) for construction of the project. McAdams prepared two design alternative pipes on all of the on-site channel areas to pipe the upstream channel areas, leaving one section of rip-rap channel in place.

This second alternative was prepared to both reduce costs from import of fill material and to save a significant number of existing trees that would be lost during the placement of fill for piping in the downstream section of the channel. Cost estimates were prepared, as well as preliminary level construction documents for the project.
