§ 721-143. Grade.

(a)

Residential driveway. Where the property to be served by the proposed construction or reconstruction of a driveway abuts on a street on which the curb is of the vertical face type and the walkway is located with its outside edge not less than three feet from the curb line, the driveway shall ramp from the grade at the edge of the walkway to a grade not less than one and three quarters inches above the gutter grade. Across the walkway and for at least one foot farther towards the street property line, the grade of the driveway shall coincide with the cross grade of the walkway. On improved streets where there are no walkways, the standard walkway grade shall be carried to the street property line. On streets having no curbs or walkways, the traveled roadway shall be considered the established grade and the slope of the driveway from the roadway to the street property line shall rise at the rate of one-half inch per foot.

Where the outside edge of the walkway is less than three feet from the curb line, the grade of the driveway shall attain the sidewalk grade in not to exceed such distance. In special cases of narrow walkways laid contiguous to the back of the curb, the length of the ramp to gutter shall be decreased to permit not less than a three foot walking space. In case of full width sidewalks, the cross grade of the walkway shall be maintained to the street property line.

(b)

Non-residential driveway. The above provisions for residential driveways shall apply except that in all cases the cross grade of the walkway shall be maintained to the street property line.
