Weapons Station Drainage Study and Master Plan
Davis & Floyd was enlisted to analyze the existing stormwater infrastructure serving the weapons station portion of Joint Base Charleston and make recommendations for stormwater infrastructure improvements. These recommendations would then be used to form the basis of a stormwater capital improvement program.
Develop hydrologic analysis for the 17,000-acre weapons station portion of Joint Base Charleston
Develop hydraulic model for the analysis of approximately 44 miles of drainage piping and 82 miles of open channel
Determine where the existing stormwater system lacks adequate capacity and make recommendation for improvements
Rate and prioritize recommended improvements according to Joint Base requirements
Provide mapping (both digital and hard-copy) of proposed improvements
Group required improvements into projects and develop programmatic level costs to complete improvements
Large project footprint of 17,000 acres
Mix of urban and rural areas, including wetlands/environmentally sensitive areas
Drainage system inventory “gaps” requiring supplemental data collection for modeling purposes
Demanding project timeline
Restricted access to areas on the base
This project provided Joint Base Charleston with the tools needed to develop a stormwater capital improvement program. Joint Base staff will be able to prioritize projects based on required level of service and available funding and ultimately provide adequate stormwater service to mission critical facilities.
