FGWB 14-0014P2A, Maintain Airfield Stormwater System Phase II & FGWB 14-0014P2B Repair Stormwater System Phase II

FGWB 14-0014P2A, Maintain Airfield Stormwater System Phase II & FGWB 14-0014P2B Repair Stormwater System Phase II: Stormwater drainage systems east of Taxiway 'J' on Dobbins ARB. Areas where the slopes have failed or where they have been disturbed from previous repair will be regraded and have sod applied to obtain stabilization and positive drainage. Work shall include all maintenance items identified in basin III, IV, and V on the airfield. In addition to the work associated with correcting the grades around the airfield, the cleaning of existing flumes, pipes, and swales is required to reestablish proper drainage patterns. New concrete flumes will be installed at various locations throughout the airfield to reestablish positive drainage and prevent future erosion and standing water. Repair and maintenance of the existing storm pipe system will be facilitated through the installation of additional access manholes throughout the drainage system. The corrections of the existing system will be attained via pipe cleaning and lining as outlined in the specifications. In areas where pipe lining is not feasible the system will be repaired through replacement of the existing system. This project will also include the removal of trees on the south side of the runway to a distance established on the approved plans. This work will be completed in and around the State Water buffer and jurisdictional wetlands.
