Site work for a water / sewer project in Portsmouth, Virginia. Completed plans call for site work for a water / sewer project.

Locations: The project location is within an existing drainage easement behind the Academy Crossing shopping center west of the High Street and Academy Avenue intersection The project includes the placement of a parallel 66-inch storm sewer trunk pipe line adjacent to an existing 91-inch by 58-inch horizontal elliptical concrete conduit behind the Academy Crossing Shopping Center. The project will require the construction of two special design junction boxes in order to connect to a double 60-inch storm sewer system at the upstream end, and a 55- inch by 72- inch box culvert below High Street at the downstream end. The alignment is directly adjacent to a cemetery located within the City of Chesapeake city limits. The placement of the parallel 66-inch pipe will require coordination with several utility companies as noted in the plans, including Dominion, Verizon, and Columbia Gas, as described on the plan set. The project also includes a new 96-inch concrete pipe parallel to the existing double 36-inch pipes under the abandoned railroad embankment to improve conveyance and reduce upstream flooding. The project will require the construction of two special head walls to connect to the new 96-inch pipes and the existing double 36-inch pipes. Grading is proposed downstream of the abandoned railroad embankment as shown in the plan set. For the placement of the new 96-inch culvert, a channel approach will need to be excavated from the inlet area of the double 36-inch culverts. For the grading and construction of the headwall at the upstream channel, it is important to minimize impacts to the two water pipeline aqueducts built on concrete piers, that are located a short distance upstream of the railroad embankment. The two water pipelines are owned by the City of Portsmouth and Norfolk respectively. Riprap is proposed adjacent to the existing piers to minimize impacts. For the grading and construction of the headwall at the downstream channel, contractor will be required to coordinate with the utility companies as noted in the plans, including Colonial Pipeline.
