Public Improvement Permit Information

Detailed information about Public Improvement Permits, for improvements proposed within the public right-of-way or on City-owned property


Public improvement permits are required for any improvements proposed within the public right-of-way (ROW) or on City property. Examples include:

  • Utility operations or service connections
  • Sidewalk improvements and driveways
  • Below or above grade improvements that use City ROW subject to encroachment conditions:
    • Tunnels
    • Sidewalk vaults
    • Stairs and ADA building entrances
    • Bus shelters
    • Retaining walls
    • Earth retaining systems (ERS)
  • Park improvements
  • Landscaped medians

Construction in City Historic Districts, City Landmarks, projects located within a City park or paid for from City General Revenue Funds, encroachments on or over public right-of-way and demolition permit applications will be referred to and approved by the Cultural Resources Office before a public improvement permit may be issued.


Permit Criteria

Each application is reviewed by multiple City Departments and Agencies depending on the type of permit, the location, and scope of the proposed work. Improvements will be reviewed with regard to the following:

  • Americans with Disabilities Act (ADA) compliance
  • Accessibility Guidelines for Pedestrian Facilities in the Public Right-Of-Way (PROWAG) compliance
  • Site civil components and stormwater drainage issues
  • Impacts to park facilities
  • Utility conflicts
  • Public safety
  • Public health
  • Historic district requirements
  • Others as deemed necessary


Permit Submission Process

Materials Needed

When submitting for any new construction application, the applicant will be required to state:

  • the location (address/cross street)
  • project contact information
  • improvement owner
  • brief description of the improvements within the ROW
  • the anticipated construction start date and duration

All applications for new construction must include final construction plans illustrating the improvements in the ROW. The engineering drawings must be 11" x 17" minimum and must be signed and sealed by a Missouri registered professional engineer and/or architect.

All drawings and plans are to follow the BPS Standard Specifications, Bid Items, and Standard Details for Street and Alley Construction. All relevant construction details from these specifications are to be included in the construction plan drawings. Your application will not be reviewed without sufficient plan drawings.

Please see our sample engineering drawings.

Use the checklist for public improvement permits to ensure that all items are complete.

Courtesy Review

BPS Design Division offers a courtesy review for projects in early design stages where an impact to the public ROW is anticipated. Applicants may submit plan drawings without seal for a courtesy review. However, the applicant does not receive a permit following a courtesy review and will have to resubmit the plan drawings once sealed drawings are ready for City review.


Approval Process

After submission, the applicant will receive a notification of any further action or deficient application items. Following review, the Board of Public Service will either ask the applicant to revise the plan drawings, or notify them that the permit application is acceptable as submitted and is being referred to the Board for final approval.

Once construction on the project is completed, the City will perform an inspection to ensure the improvements were constructed as specified in the permit. The City will follow up with the applicant regarding any deficiencies.
