GRADING PLANS AND PERMIT PROCESSING
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.
For your information, included is a flow chart of the grading permit process and the grading permit application. Supplemental information is also required in accordance with the Grading Manual (Article 5).
