Grading Plan Processing

GRADING PLANS AND PERMIT PROCESSING

Grading Permits

There are two types of grading permits:  Preliminary and Precise.  Preliminary grading permits allow for earthwork and storm drain construction only, while Precise grading permits are for building pad certification and any on-grade construction (paving, hardscape, etc.). A Preliminary grading permit is not needed for every project and Building permits can only be issued from a Precise grading permit.  In accordance with the City of Irvine’s Local Implementation Plan (LIP), a Water Quality Management Plan (WQMP) is required for all priority Precise grading plan submittals, and may be required for Preliminary grading submittals.
