County, Community Reach Consensus on Huntington Levee Design Features
County staff and the Huntington community recently reached agreement on several key design alternatives on the conceptual design for the Huntington levee and pumping station. The levee will protect homes and other property against the rising levels of Cameron Run during severe storm events up to the level of the 100-year storm.
During the meeting, staff presented design considerations and recommendations and addressed questions and concerns from the community. Four key design considerations that were agreed to include:
- The use of a collection drain to prevent the flow of water under the levee and protect structural integrity of the levee
- The placement of the pumping station at the eastern end of the levee
- The construction of an underground box culvert along the base of the levee to convey stormwater from the protected side of the levee to the pumping station
- The construction of a levee which is a combination of an earthen embankment with a four-foot high I-wall along the top of the embankment.
Consensus on these key design features enables the project team to commence hydraulic modeling and additional analysis to develop the detailed design of the levee and pumping station.
Phase II of the project design includes the schematic design, design development, federal, state and local permitting, land acquisition, creation of construction documents and bidding. The process will also include environmental and other reviews by state and federal agencies.
Construction on the levee, phase III, is anticipated to begin in the early part of 2017 and last through spring 2019.
Voters approved a $30 million stormwater bond in November 2012 to fund the construction of the levee and pumping station. The levee will protect 160 homes in the Huntington neighborhood where residents have suffered the impacts of three flood events in the last 12 years.
