REPAIR & MAINTAIN AIRFIELD STORMWATER SYSTEM PHASE II

While not all inclusive, this project encompasses the work necessary to repair the stormwater drainage systems east of Taxiway 'J' on Dobbins ARB. Areas where the slopes have failed or where they have been disturbed from previous repairs 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.
