13. Typical roadway cross section for all roadways, existing or proposed, within <br />and adjacent to the proposed development. These cross sections shall <br />appear on the detail sheet, or if no detail sheet has been used, on the first <br />sheet of the submittal showing roadway design. They shall indicate type of <br />roadway(s), profile grade design point (centerline, flow -line, top of curb, lip <br />of gutter, etc.), roadway width, right-of-way, type of curb, gutter and <br />sidewalk as required, pavement cross slope, pavement thickness, and <br />structural material components of the pavement, base and subbase, <br />together with specifications for treatment of subgrade and installation of <br />pavement structural members. <br />14. Construction plans for any roadway improvements including intersections <br />requiring signalized traffic control. The construction plans shall include <br />construction and lane details for the new construction and existing facilities <br />a minimum of 150 ft beyond the limits of construction. <br />15. Basis of plan view and profile elevations shall be the same, i.e. flowline and <br />flowline, top of curb and top of curb, etc. <br />B. Profile <br />The profile shall include, but not be limited to, the following: <br />1. Original ground (dashed) and design grade (heavy, solid). Both grades are <br />to be plainly labeled. <br />2. For six inch vertical curb and gutter, all design elevations shall be centerline, <br />lip of gutter, or flowline (preferred). For combination of curb, gutter and <br />sidewalk, all design elevations shall be back of sidewalk, lip of gutter, or <br />flowline (preferred). The basis of record drawing information shall be the <br />same as the design (both flowline or both top of curb, etc.). <br />3. Stationing continuous for the entire portion of the roadway shown in the <br />plan view, with the centerline station of all non -single family driveways and <br />all intersecting roadways clearly labeled. <br />4. All existing curbs, gutters, sidewalks and pavement adjacent to the <br />proposed design. Basis for existing grades shall be as -built elevations at <br />intervals not to exceed 25 feet. Previously approved designs are not an <br />acceptable means of establishing existing grades. <br />5. Elevation and location of all existing and new utilities in the immediate <br />vicinity of the construction shall be shown on the plans. <br />6. Station and elevation of all vertical grade breaks, existing (as -built) and <br />proposed. <br />7. Distance and grade between VPI's. <br />8. Vertical curves, when necessary, with VPI, VPC, and VPT, high or low point <br />(if applicable) stations and elevations. All vertical curves shall be labeled <br />with length of curve (L) and K=L/A where A is the algebraic difference in <br />slopes, in percent. <br />9. Profiles for all curb returns (except medians). <br />C. Notes <br />In addition to other notes required in these Standards, the following notes shall appear <br />on the cover sheet of all submittals containing roadway plans. If a cover sheet has not <br />
