THE LANDING WIDTH SHALL BE EQUAL TO RAMP WIDTH. PROVIDE ADA COMPLIANT DETECTABLE WARNING SURFACES ON BOTTOM GRADE BREAK OF EACH RAMP. DETECTIBLE WARNING SHALL COVER THE ENTIRE WIDTH OF RAMP (EXCLUDING FLARED SIDES) AND BE A MINIMUM OF 2 FEET LONG IN THE DIRECTION OF TRAVEL. BOTTOM GRADE BREAKSHOULD GENERALLY BE LOCATED AT BACK OF CURB AND BOTH ENDS OF BOTTOM GRADE BREAK SHOULD BE LESS THAN 5 FEET FROM BACK OF CURB. THE DESIRABLE SLOPE OF FLARE IS 8.3% (1:12) OR FLATTER. THE MAXIMUM SLOPE OF FLARE IS 10% (1:10). FLARES BETWEEN RAMPS MAY NOT REACH FULL HEIGHT OF STANDARD CURB. CONSTRUCT STANDARD CURB SECTION BETWEEN RAMPS ONLY WHEN MAXIMUM FLARE SLOPE IS NOT EXCEEDED. CURB EXPANSION JOINT SHALL NOT BE LOCATED IN RAMP. STORM DRAIN INLET SHALL BE CONSTRUCTED "UPSTREAM" OF RAMPS.
