The culvert inverts will be buried 1 ft. and there will be a 2 ft. high concrete (Description of Minimization of Water sill at the inlet end of the high flow barrel.

Avoidance and Minimization Efforts: THE CULVERT INVERTS WILL BE BURIED 1 FOOT. LOW FLOW WILL BE CONVEYED THROUGH TWO 10 FT. WIDE BARRELS. THE (Bridge to Culvert) SLOPE OF CULVERT WILL BE VERY MILD AT 0.22°/a. LOW FLOW SILLS/BAFFLES WILL NOT BE NECESSARY. ONE 10 FT. WIDE BARREL WITH A 2 FT. HIGH SILL AT INLET END WILL CONVEY HIGH FLOWS.

OF C�EARANCE BETWEEN LOW CHORD AND WATER SURFACE. THE EXISTING ROAD IS OVERTOPPED BY THE 2-YR. RAINFALL EVENT. THE PROPOSED DESIGN WILL RAISE THE ROAD GRADE APPROXIMATELY 2 FT. AT THE BRIDGE AND WILL IMPROVE THE HYDRAULIC LEVEL OF SERVICE TO 2-YR. EVENT. DUE TO THE STEEP ROADWAY APPROACH GRADES (15.2% AND 5.9%) A CORED SLAB BRIDGE COULD NOT BE USED. IF A CONCRETE GIRDER BRIDGE WAS USED, THE ROAD GRADE WOULD HAVE TO BE RAISED CONSIDERABLY IN ORDER TO ACHIEVE ADEQUATE FREEBOARD BETWEEN LOW CHORD AND WATER
