DOMINION BOULEVARD CORRIDOR STUDY | Chesapeake, Virginia
112 | Infrastructure Strategy
Water System
The existing water infrastructure through the Dominion Corridor generally follows the
same alignment as the sewer system. Based on City GIS (geographic information system)
information, the majority of the transmission and distribution lines were installed in the
2000’s and range in size between 4” – 24”. The majority of the lines are comprised of
ductile iron and PVC pipe with a few lines being comprised of cast iron pipe. There is
approximately 101,000 linear feet of active pipe within the Corridor. Service is primarily
confned to the same areas where sewer service is available. There is an existing 8” line
that serves a City training facility that runs down George Washington Highway and enters
the Corridor along Number Ten Lane. The remainder of the Corridor is served by private
well systems, including the Airport.
The major transmission mains currently serving the area within the Corridor are located
along Dominion Boulevard and Cedar Road and range in size from 16” – 24”. There is also
a 16” and 12” transmission main loop that runs down Grassfeld Parkway from Dominion
Boulevard and connects to Cedar Road at the Cahoon Parkway intersection. A 16”
transmission main extends south on Scenic Parkway from Dominion Blvd.

PROGRAM PROJECTIONS
Sewer System
Based on the market research study performed by RCLCO, Areas 3, 4, 5 and 6 were
determined to be able to support economic growth.
Design Workshop provided Woolpert with Program Allocations which included square
footage projections for Retail, Office and Industrial space and number of projected units for
Residential space. From these allocations, flows for each Area were generated using the
guidelines and requirements set forth in the Regional Technical Standards (RTS).
Chesapeake’s existing pump stations were used as a comparison point for projecting
approximate pump station size throughout the Corridor. The largest existing pump station
within the Corridor is Pump Station 261, with capacity of 500,000 gallons per day (GPD).
For this report, it was assumed that the flows produced by the projected development
throughout the Corridor would be handled with new infrastructure and new pump stations.
However, existing pump stations have some capacity for increased flow. If pump stations
similar in size to existing Pump Station 261 are built, then the flows generated by the
Program Allocations may require construction of fve new pump stations in the targeted
development areas.
Through several internal discussions and close coordination with HRSD personnel,
Chesapeake Utilities and HRSD have agreed upon the installation of a new HRSD Interceptor
Force Main through the Dominion Corridor. The conceptual alignment of the Interceptor
Force Main will follow a primary right-of-way through the corridor. The future Interceptor
Force Main will connect to existing HRSD infrastructure at Cedar Road on the north western
side of the Corridor and on Battlefeld Boulevard, east of the Corridor. The connection east
of the corridor will be made at either the Hillwell Road or Hillcrest Parkway intersection.
The future alignment through the Corridor will depend on the magnitude of development
and need for easements or right-of-way acquisition. Alignment options can be seen
on fgure 73. In the past, flows have been modeled by HRSD to connect to the existing
interceptor system at Hillwell Road. HRSD’s main requirement is that the future interceptor
