PERPENDICULAR CURB RAMP AND LANDING, CONSIDER
USING A COMBINED (PARALLEL/PERPENDICULAR) CURB
RAMP. COMBINED (PARALLEL/PERPENDICULAR) CURB
RAMPS ARE TO MEET THE CRITERIA FOR BOTH THE PARALLEL
AND PERPENDICULAR CURB RAMPS. (SEE DETAILED DRAWING
NUMBER 608-30 AND THIS DRAWING.)
2 THERE IS NO TOLERANCE FOR EXCEEDING MAXIMUM STANDARDS.
3 THE COST OF RETAINING WALLS IS INCLUDED IN THE UNIT
PRICE BID FOR CONCRETE SIDEWALK.

CURB RAMPS
1 USE CURB RAMPS IN THE FOLLOWING ORDER OF PREFERENCE:
A. PERPENDICULAR CURB RAMP.
B. COMBINED (PARALLEL/PERPENDICULAR) CURB RAMP.
C. PARALLEL CURB RAMP.
EXISTING CONDITIONS SUCH AS R/W, SIDEWALK WIDTH,
AND TYPE OF SIDEWALK (CURB-TIGHT OR BUFFER AREA)
USUALLY DETERMINE THE TYPE OF CURB RAMPS TO USE.
A SINGLE CURB RAMP OR BLENDED TRANSITION CORNERS
SERVING TWO STREET CROSSING DIRECTIONS ARE NOT
ALLOWED IN NEW CONSTRUCTION AND NOT RECOMMENDED
WHEN ALTERING EXISTING FACILITIES.
2 WHEN ALTERING EXISTING FACILITIES, MEET NEW
CONSTRUCTION REQUIREMENTS FOR CURB RAMPS TO THE
MAXIMUM EXTENT FEASIBLE. DOCUMENT WITH AN ADA
STATEMENT OF TECHNICAL INFEASIBILITY FORM WHEN ADA
STANDARDS CAN'T BE ACHIEVED .
3 IF POSSIBLE, DO NOT PLACE DRAINAGE STRUCTURES IN
CONFLICT WITH CURB RAMPS. LOCATION OF CURB RAMPS
TAKES PRECEDENCE OVER LOCATION OF DRAINAGE
STRUCTURES EXCEPT WHERE EXISTING DRAINAGE
STRUCTURES ARE BEING UTILIZED. IF A DRAINAGE
STRUCTURE MUST BE PLACED IN THE PEDESTRIAN ACCESS
ROUTE, AN ADA COMPLIANT GRATE, HAVING SLOT OPENINGS
1/2" [13] OR LESS IN ONE DIRECTION, MUST BE USED.
4 USE THE FLATTEST SLOPES POSSIBLE (5% MIN.) FOR ALL
CURB RAMPS. MAXIMUM CONSTRUCTED RAMP SLOPES OF
8.3% ARE SHOWN FOR GUIDANCE AT DIFFICULT SITES.
5 FINAL FIELD LOCATION OF THE CURB RAMPS WILL BE
DETERMINED BY THE PROJECT MANAGER.
6 PEDESTRIAN ACCESS POINTS AT CROSSWALKS ARE TO
BE WHOLLY CONTAINED WITHIN THE CROSSWALK LINES.
7 FOR ADDITIONAL INFORMATION CONSULT:
DRAFT PUBLIC RIGHTS-OF-WAY ACCESSIBILITY
GUIDELINES (PROWAG)
1 OBTAIN A SURFACE TEXTURE ON THE RAMP BY COARSE
BROOMING, TRANSVERSE TO THE RAMP SLOPE.
2 TAKE CARE DURING CONSTRUCTION TO ASSURE UNIFORM
RAMP GRADES, FREE OF SAGS AND SHARP GRADE CHANGES.
