Slopes at least 0.50% less than the maximum are preferred. o ac S S rf Flared Side ss lo u ro p s C e 2. Ramp or Blended Transition. A ramp or blended transition shall be used to lower or raise the sidewalk to connect with the street or highway. Clear Space re la F e op 3. Turning Space. A turning space shall be provided at the top of a perpendicular ramp, bottom of a parallel ramp, or where the pedestrian travel requires a Sl change in direction. A common turning space may be shared by adjacent ramps. The turning space shall have a minimum clear dimension of 4 ft x 4 ft. Pedestrian Where the turning space is constrained at the back of the sidewalk by a curb, retaining wall, building, or feature over 2 inches in height, the minimum clear Street dimension shall be 4 ft x 5 ft, with the 5-ft dimension in the direction of the ramp running slope. Crossing Detectable Warning 4. Flared Side. A flared side shall be used adjacent to a walkable surface. A flared side may be used adjacent to a non-walkable surface. A flared side shall have Crosswalk Surface a maximum slope of 10.00% measured parallel to the back of the curb. Markings
5. Return Curb. A return curb is placed perpendicular to the roadway curb. A return curb may be used adjacent to a non-walkable surface. A return curb shall Curb Flush with Pavement not be used adjacent to a walkable surface. The return curb may be omitted where the non-walkable surface is flared and the curb adjacent the roadway is and Gutter Line tapered to meet the flush curb at the bottom of the ramp.
6. Clear Space. A clear space shall be provided beyond the bottom grade break of a curb ramp wholly contained within the crosswalk and wholly outside the parallel vehicular travel path. The clear space shall have a minimum clear dimension of 4 ft x 4 ft. TYPICAL CURB RAMP COMPONENTS 7. Detectable Warning Surface. A detectable warning surface shall consist of truncated domes and be placed at each street, highway, or railroad crossing. The detectable warning surface shall extend a minimum of 2 ft in the direction of pedestrian travel and be placed the entire width of a ramp, blended transition, or turning space.
8. Running Slope. The running slope of a ramp, blended transition, or turning space shall be measured parallel to the direction of pedestrian travel. a. A running slope of 2.00% or less is considered level. b. A ramp shall have a maximum running slope of 8.33% but shall not require a ramp length to exceed 15 ft. INDIANA DEPARTMENT OF TRANSPORTATION c. A blended transition shall have a maximum running slope of 5.00%. d. A turning space shall have a maximum running slope of 2.00%. CURB RAMP DRAWING INDEX 9. Width. Unless otherwise noted, minimum width of a ramp, blended transition, or turning space, excluding flared sides or return curb, shall be 4 ft. AND GENERAL NOTES 10. Grade Break. A grade break at the top and bottom of a ramp, blended transition, or turning space shall be perpendicular to the running slope. Grade breaks shall not be within the ramp, blended transition, turning space, or detectable warning surface. Grade breaks shall be flush. Vertical discontinuities shall not be SEPTEMBER 2018 greater than 1/2 in. Where a discontinuity is greater than 1/4 in. the surface shall be beveled with a slope not steeper than 1V:2H.
11. Cross Slope Exceptions. The cross slope of a ramp, blended transition, or turning space shall be measured perpendicular to the direction of pedestrian travel. STANDARD DRAWING NO. E 604-SWCR-01 a. The maximum cross slope at a pedestrian street crossing without yield or stop control shall be 5.00%. b. The maximum cross slope at a pedestrian street crossing with yield or stop control shall be 2.00%. W. P c. The maximum cross slope at a midblock crossing shall be the established grade of the adjacent roadway. H H T I E L ISTER L B EG E R D I A P /s/ Elizabeth W. Phillips 03/20/18 12. Counter Slope.

Drainage inlets should be located uphill from a curb ramp to prevent ponding in the path of pedestrian travel. NOTES:
1 Where insufficient width between the curb and back of sidewalk prevent a standard perpendicular curb ramp running slope, a sidewalk transition may be used to lower the sidewalk grade. The sidewalk transition running slope shall not exceed 8.33%. See Standard Drawing Series E 604-SDWK for sidewalk details.
2. The turning space shall have a minimum clear dimension of 4 ft x 4 ft and a running slope of 2.00% maximum.
