When an application for a building permit with DBI includes work that has an impact on the sidewalk, curb and gutter, pavement, or any other facilities in the public right-of-way, DPW/BSM will review the plans and perform an engineering inspection at the location for which building permit is issued to determine whether a Street Improvement Permit is needed.

City Standard Specifications
- Section 204.04 Slope – Unless otherwise specified, the finished surface of the walk shall rise 1/5 inch per foot from curb to the property line.
- Section 202.01 Concrete Curb – Unless otherwise specified, the nominal specified height of curb measured from gutter to top of curb shall be 6 inches.
- Standard Residential curb cut – (10’) feet long by (3’) feet wide including (18”) inches for the wings. If longer than (10’) feet, the Planning Department must approve non-City Standard curb cuts. Curb cuts 30 feet or longer require an Overwide Driveway Permit from DPW.
- Standard ADA curb ramp – Ramping: Transitions from ramps to walks, gutters, or streets shall be flush and free of abrupt changes. Maximum slopes of adjoining gutters, road surface immediately adjacent to the curb ramp, or accessible route shall not exceed 1:12 (8.33%). Truncated domes shall be provided and oriented such that the rows are parallel with the direction of the ramp. Wings: If a curb ramp is located where pedestrians must walk across the ramp, it shall have flared sides; the maximum slope of the flare shall be 1:10 (10%). A curb ramp shall have a detectable warning band of 12” inches. The detectable warning shall extend the full width and depth of the curb ramp.
