Home My WebLink AboutFDP201800022 Study 2018-12-188FE DETERMINATION NARRATIVE THE OWNER OF THE KEYS ACADEMY AT 3020 FONTAINE AVENUE IN ALBEMARLE COUNTY, VIRGINIA IS PROPOSING TO EXPAND THE CURRENT USE OF THE BUILDING TO USE THE LOWER LEVEL FOR CLASSROOMS. HOWEVER, THERE IS A ZONE A FLOOD ZONE LOCATED ON THE PROPERTY AS SHOWN ON FEMA MAP 51003CO269D, EFFECTIVE DATE 2/4/2005. IN ORDER TO DETERMINE THE 100-YEAR WATER SURFACE ELEVATION ON THE PROPERTY, THE FOLLOWING PROCEDURE WAS USED IN ACCORDANCE WITH THE FEMA GUIDANCE ON DETERMINING BFES IN ZONE A AREAS. FIRST, SCS METHODOLOGY WAS USED TO COMPUTE THE PEAK 100-YEAR FLOW OF 2,030 CFS FOR THE 1,977-ACRE DRAINAGE AREA FLOWING TO THE DOWNSTREAM TRIPLE 8'W X 10'H BOX CULVERTS THAT CONVEY RUNOFF UNDER THE ROUTE 29/250 BYPASS. THEN, THE HEADWATER WAS COMPUTED AT THE TRIPE BOX CULVERTS FOR INLET CONTROL WHICH IS THE CONTROLLING FLOW REGIME. BACKWATER WAS ASSUMED TO STEP UPSTREAM AT THE SAME SLOPE AS THE STREAM CHANNEL. THE 100-YEAR WATER SURFACE ELEVATION AT THE KEYS ACADEMY BUILDING LOCATED 260' UPSTREAM WAS COMPUTED TO BE 435.3. THE ELEVATION IN THE EXISTING CHANNEL WAS CHECKED USING THE MANNING'S FORMULA TO ENSURE THE CONTROLLING ELEVATION WAS DERIVED FROM THE CULVERT HEADWATER ELEVATION.
