General Notes DISCLAIMER: The use of this standard is governed by the "Texas Engineering Practice Act". No warranty of any kind is made by TxDOT for any purpose whatsoever. TxDOT assumes no responsibility for the conversion of this standard to other formats or for incorrect results or damages resulting from its use. Curb s 1. Install a curb ramp or blended transition at each pedestrian street crossing. 2. All slopes shown are maximum allowable. Lesser slopes that will still drain properly should be used. Adjust curb ramp length or grade of approach sidewalks as directed. 3. The minimum sidewalk width is 5. Where the sidewalk is adjacent to the back of curb, a 6 sidewalk width is desirable. Where a 5 sidewalk cannot be provided due to site constraints, sidewalk width may be reduced to 4 for short distances. 5 x 5 passing areas at intervals not to exceed 200 are required. 4. s shall be 5 x 5 minimum with a maximum slope in any direction. 5. Maneuvering space at the bottom of curb ramps shall be a minimum of 4 x 4 wholly contained within the crosswalk and wholly outside the parallel vehicular travel path. 6. Maximum allowable cross slope on sidewalk and curb ramp surfaces is. 7. Provide flared sides where the pedestrian circulation path crosses the curb ramp. d sides shall be sloped at 10% maximum, measured parallel to the curb. Returned curbs may be used only where pedestrians would not normally walk across the ramp, either because the adjacent surface is planted, substantially obstructed, or otherwise protected. 8. Additional information on curb ramp location, design, light reflective value and texture may be found in the current edition of the Texas Accessibility Standards (TAS) and 16 TAC 68.102. 9. To serve as a pedestrian refuge area, the median should be a minimum of 6 wide, measured from back of curbs. Medians should be designed to provide accessible passage over or through them. 10. Small channelization islands, which do not provide a minimum 5 x 5 landing at the top of curb ramps, shall be cut through level with the surface of the street. 11. Crosswalk dimensions, crosswalk markings and stop bar locations shall be as shown elsewhere in the plans. At intersections where crosswalk markings are not required, curb ramps shall align with theoretical crosswalks unless otherwise directed. 12. Handrails are not required on curb ramps. Provide curb ramps wherever on accessible route crosses (penetrates) a curb. 13. Curb ramps and landings shall be constructed and paid for in accordance with Item 531 "Sidewalks". 14. Place concrete at a minimum depth of 5" for ramps, flares and landings, unless otherwise directed. 15. Provide a smooth transition where the curb ramps connect to the street. 2-0" Min.

Curbs shown on sheet 1 within the limits of payment are considered part of the curb ramp for payment, whether it is concrete curb, gutter, or combined curb and gutter. Existing features that comply with TAS may remain in place unless otherwise shown on the plans. Detectable Warning Pavers 24. Furnish detectable warning paver units meeting all requirements of ASTM C-936, C-33. Lay in a two by two unit basket weave pattern or as directed. 25. Lay full-size units first followed by closure units consisting of at least 25 percent of a full unit. Cut detectable warning paver units using a power saw. Sidewalks Detectable Warning Material 18. Curb ramps must contain a detectable warning surface that consists of raised truncated domes complying with Section 705 of the TAS. The surface must contrast visually with adjoining surfaces, including side flares. Furnish and install an approved cast-in-place dark brown or dark red detectable warning surface material adjacent to uncolored concrete, unless specified elsewhere in the plans. 26. 27. Provide clear ground space at operable parts, including pedestrian push buttons. Operable parts shall be placed within one or more reach ranges specified in TAS 308. Place traffic signal or illumination poles, ground boxes, controller boxes, signs, drainage facilities and other items so as not to obstruct the pedestrian access route or clear ground space. 19. Detectable Warning Materials must meet TxDOT Departmental Materials Specification 28. Street grades and cross slopes shall be as shown elsewhere in the plans. DMS 4350 and be listed on the Material Producer List. Install products in accordance 29. Changes in level greater than 1/4 inch are not permitted. SHEET 2 OF 4 with manufacturer s specifications. 20. 21. Detectable warning surfaces must be slip resistant and not allow water to accumulate. Detectable warning surfaces shall be a minimum of 24" in depth in the direction of pedestrian travel, and extend the full width of the curb ramp or landing where the pedestrian access route enters the street. 30. The least possible grade should be used to maximize accessibility. The running slope of sidewalks and crosswalks within the public right of way may follow the grade of the parallel roadway. Where a continuous grade greater than 5% must be provided, handrails may be desirable to improve accessibility. Handrails may also be needed to protect pedestrians from potentially hazardous conditions. If provided, handrails shall comply with TAS 505. Texas Department of Transportation Design Division Standard PEDESTRIAN FACILITIES 22. Detectable warning surfaces shall be located so that the edge nearest the curb line is at the back of curb. Align the rows of domes to be perpendicular to the grade break between the ramp run and the street. Detectable warning surfaces may be curved 31. Handrail extensions shall not protrude into the usable landing area or into intersecting pedestrian routes. CURB RAMPS 23. along the corner radius. Shaded areas on Sheet 1 of 4 indicate the approximate location for the detectable warning surface for each curb ramp type. 32.
