Engineering Reviews

Engineering Review Requirement Thresholds

The Engineering Department must review permit applications that meet certain thresholds. If these thresholds are met, applicants must schedule a pre-submittal sufficiency review meeting with a Development Engineer.

The thresholds for Engineering Department review of permit applications are:

  • The project will increase impervious area (this includes adding hard surface patios, increasing the footprint of the house, etc.)
  • The project will disturb less than 200 square feet of land (this includes grading, even if a structure or hard surface is not added)
  • Impervious area will be “scraped and replaced”
  • Snowmelt is added or repaired

Review the Complete Engineering Review Thresholds and Requirements.

Engineering Sufficiency Review Meetings

If your project requires an Engineering sufficiency review meeting, complete the sufficiency checklist (PDF) and supporting documents prior to this meeting, as they will be reviewed during the meeting.

If the Engineering review thresholds are met, the Development Engineer’s signature on the sufficiency checklist (PDF) is required to submit a permit application.

Additional Information

All Engineering requirements and standards are laid out in the Engineering Design Standards document. Additional thresholds and requirements for your project are described on our Understand Permit Requirements page.
