1. Lengths and widths between all elevation points along grade breaks and sides of all <br />curb and gutter, ramps, wings, landings and associated concrete walk; <br />2. Lengths and widths of all sides of the ramps, truncated dome surfacing, landings, and <br />sidewalk leading into the landings, and lengths of curb and gutter that are not <br />included in the first bullet; and <br />3. All other lengths and widths of associated concrete walk improvements needed to <br />complete the Access ramps as shown on the special detail plans. <br />Access ramp drawings shall also include design elevations for all features of the new <br />improvements, including but not limited to: <br />1. Elevations for the flow line of the gutter and the top of curb: <br />a. Where each side (when extended past the depressed curb) of the ramps intersect <br />the gutter; <br />b. At break points for the wings; <br />c. At grade break points in the curb and gutter; <br />d. At match points to existing curb, and at other points as needed for a complete <br />design. <br />2. Elevations in the ramps, wings and landings: <br />a. At all grade break points; <br />b. At all match points to existing walk, and at other points as needed for a complete <br />design. <br />Also see Section 2.05 Intersection standards. <br />B. Clearance <br />The minimum vertical clearance from obstructions above sidewalks is as follows: <br />• 7 feet from the bottom of a sign <br />• 8 feet from building overhangs <br />• 7 feet from awnings <br />• 9 feet from overhanging vegetation, such as tree limbs <br />C. Grading Type <br />The standard grading type for sidewalks is setback; alternate designs are subject to the <br />standards noted below.
