Permits for Public Works Improvements

Public Improvements
Most construction that takes place within the City requires the review of the Public Works/Development Services Department. Any improvements related to subdividing, site construction and other public improvements requires a planned design by a registered engineer that has been completed according to the City of Liberty’s Design Criteria and Technical Specifications.

City Public Improvement Permit Application Requirements


Upon approval of the plans by the City Engineer, the required Permit may be obtained for construction. The following items are required to be submitted in the public improvement permit package:
For developments within a 100-year floodplain, a City Floodplain Development Permit (PDF) is required.

If the project involves blasting, a City of Liberty Blasting Permit Application (PDF) is required. 

Land Disturbance
Any Project, public or private, disturbing one or more acres of land within the City of Liberty are subject to storm water quality management standards in accordance with the Missouri Department of Natural Resources (MDNR) land disturbance requirements.  Such projects require obtaining a City of Liberty Land Disturbance Permit (PDF) and an MDNR Land Disturbance Permit.
