Engineering Development Process

Guidance Through the Development Process

To assist you through the development review and permitting process, we have created a guide with valuable information to help you better understand our process. The "Civil Engineering Development Process and Requirements" document outlines and defines the Civil Development process steps for all commercial development projects requiring public improvements including grading, paving and utilities. It also contains the contact information and links to the City of McKinney Design Manuals, Standards and General Notes.


To provide you with the best possible service, we have also implemented an online Customer Self Service (CSS) portal where you will now apply online for your development permits. Through this portal, you will also submit the required documentation for your development projects that require public improvements for grading, paving and utility work.


Please note that for all commercial development projects requiring public improvements, a development permit is required in addition to any required commercial building permits.  A separate tree permit application is also required prior to the initiation of construction.  


All applicable fees must be paid before a permit will be issued.
