Owner Objective

The City of Martinsburg, West Virginia wanted to improve stormwater conveyance by rerouting existing stormwater infrastructure in order to promptly activate an existing pump system.

This pump system is needed due to the site being the natural low spot of the surrounding area. This situation created a unique drainage issue requiring extensive and specific structure use to mitigate flooding during storm events. Due to the project site being in a sinkhole hotspot and the inherent hardness of the rock in the area, the installation of the proposed stormwater piping required considerable effort. The depth at which the structures and piping need to be installed was also a factor due to the safety requirements for both the contractor and the public. 

CEC Approach

CEC provided site plans for extensive stormwater infrastructure upgrades in an approximately 500-foot section of South Raleigh Street. The project included the installation of over 500 liner feet of piping, six new inlet structures, and five manhole structures. These upgrades allow for stormwater diversion and conveyance into the existing pump system, reducing system wide backup and flooding during larger storm events. In addition to the below grade improvements made on the street, Sidewalk, curb and gutter, and driveway improvements were also made to accommodate the newly installed stormwater structures and provide for safer pedestrian movement through the area from nearby schools.
