Street Improvement


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, Public Works 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. When making improvements to the Public Right of Way, you may also consider replacing gray concrete with greenery. Click here to see projects that have included greening, or visit our sidewalk landscaping page for more information.
