GET READY TO WORK
Understand Permit Requirements
To get through the permitting process with minimal delays, you need to submit applications that are complete and compliant with city and state requirements. This includes submitting ALL required forms and documentation, in a format that can be easily understood.

 

To assist you, the City has developed a Resource Center with a section specific to grading, excavating and using the public right of way.You can also find the relevant required documents, based on the size and scale of your project below.

 

Thresholds for Engineering Reviews:

If your project meets the following list of thresholds*, be prepared to submit the relevant documents to the Engineering Department. Please be aware that your project may meet more than one threshold, which would require you to submit requirements from multiple rows in the table below:

*Please note that the thresholds listed above are not  exhaustive of every instance that may require particular reviews. Please consult with the Engineering department prior to proceeding with your project to ensure you are meeting all requirements.

Be aware that many projects require more than one permit.
For instance, projects may require a building permit (a #1 permit), sub-permits for plumbing, electrical and mechanical work, in addition to permits for exterior work such as grading and excavating.

 

Always check to see which permits may be applicable in your situation, using our List of Construction-Related Permits and Triggers.

 

Construction Mitigation Plan (CMP):

 

You must submit a Construction Mitigation Plan if any of the following apply:

  • Interior and/or exterior disturbance exceeding 1000 SF
  • Building structure disturbance exceeding 400 SF
  • Change in ownership or contracting services
  • Modifications desired to an approved CMP
To learn more about CMP's, please visit our Construction Mitigation Planning Page .
