Project: Lake Bradford/Chubb Lake Storm water Pump Station Design-Build Project. The City of Virginia Beach is requesting Statements of Qualification from qualified Design-Builders that have experience in the design and construction of large capacity storm water pump stations (greater than 100 cubic feet per second (cfs) is strongly preferred), tide gates, flood barriers, and drainage system improvements, for the design and construction of the Lake Bradford/Chubb Lake Storm water Pump Station Project ("The Project"). Questions pertaining to the Project should be directed to Francisco Barros at fbarros@vbgov.com. Project Description
A. The Lake Bradford/Chubb Lake project area has experienced repeated flooding events
throughout the years. The flooding events are caused by the area's low elevations, tidal
influence, undersized drainage systems, and storm events. This Project's goal is to reduce
the impact of these flooding events through a series of drainage improvements that
include a pump station, tide gate, channel dredging, and dune restoration.
B. The Project consists of the following:
1. Stormwater Pump Station: This projectincludesthe design and construction of a large
capacity (500 cfs peak, 375 cfs firm), multi-bay pump station located adjacent to
Chubb Lake. The structure will be located within an easement on Joint Expeditionary
Base Little Creek property. An intake structure will be located on Chubb Lake. The nverts of the intake structure may require channel dredging. The outfall pipes will
directly discharge to the beach, requiring an energy dissipator.
2. Tide Gate/Outlet Control Structure: This structure will be constructed in the existing
outfall channel and adjacent to Lake Bradford. The structure will be located within
an easement on Joint Expeditionary Base Little Creek property. The structure will
prevent downstream storm tides from backing up into Lake Bradford & Chubb Lake.
Additionally, this structure will also prevent stormwater runoff from Lake Bradford
and Chubb Lake from drainage through Joint Expeditionary Base Little Creek.
