Grading Plan Processing
 

 

General Information:
This information has been compiled to assist you in processing grading plans through the City of Irvine. There are two types of grading permits: preliminary and precise. The permit application and supplementary information for the preliminary and precise grading are submitted to the City of Irvine, Permit Processing Counter, Community Development Department, Building and Safety Division, One Civic Center Plaza, Irvine, California 92623-9575, (949) 724-6300. You will note zoning conformance approval must precede grading permit submittal. The Community Development staff will check the submittal for conformance with the requirements listed below and will assist in the completion of the application.

The Process:
For your information, the following data is included: A flow chart of the grading permit process, a copy of the grading application, typical grading bond forms, letter of credit, and Engineering cost estimate form. Should any questions arise regarding the application process, the applicant is encouraged to contact the Community Development Department for information.

Once the tentative map for a parcel or tract is approved and zoning cleared, a grading plan can be submitted. However, tentative map approval is not required prior to the issuance of certain preliminary grading permits. The applicant should allow 15 working days for the first plan check and 10 working days for any subsequent check of preliminary and precise grading plans. Inspection fees and a bond are required prior to issuance of the grading permit. Inspection fees are calculated based on the total acreage of the project site, and a set unit cost per square foot of hardscape. A bond is calculated based on the amount of cut or fill (whichever is the largest) and 100% of the cost of the total drainage improvements (including any pavement).
