Mosquito Control of Savannah Disposal Areas

DMCA Mosquito Control Services Contract provides services, including furnishing personnel, transportation, mobilization and demobilization, equipment and materials required in connection with mosquito control: The work is located adjacent to the Savannah Harbor in DMCAs 1N and 2A in Chatham County, Georgia and 12A, 13A, 13B, 14A and 14B in Jasper County, South Carolina. The containment areas vary from several hundred to over a thousand acres, with interiors of dredge sediments consisting of highly saturated soft silty soils interbedded with sand lenses overlying marsh deposits. The containment areas are sometimes kept water filled in order to meet mitigation requirements but must be drained for exterior dike raisings. To accelerate drying, dewatering occurs as soon as possible in the chosen areas. Services include monitoring USACE DMCAs adjacent to the Savannah Harbor for mosquito production, treating mosquito populations affecting disposal sites using IPM strategies, performing physical spoil activities (ditching) as necessary at the DMCAs to reduce sources of mosquitoes, and development and implementation of a Pesticide Discharge Management Plan (PDMP) to minimize pesticide use. IPM will include, but not be limited to, ditching/dewatering strategies utilizing 20’ by 20’ wide and 12’ deep sump pits at 23 weirs; up to 150,000 feet of 12' wide x 10' deep manifold ditches, and up to 50,000 feet of 8’ wide x 8’ deep finger ditches; and pesticide application covering approximately 5,500 acres. Work is intermittent due to the saturated condition of the containment areas.
