Before grading work begins, City staff must review the grading and clearing plans. The City Engineer usually approves the issuance of a grading permit, but in some circumstances City Council authorization is required.
Grading and Clearing Permit required before:
1- excavation, fill or rearrangement of 300 or more cubic yards of earth
materials on any site;
2- grading of an area where the average slope of the area to be excavated or
filled exceeds 5-to-1 (20 percent);
3- excavation or fill of any portion of a site that increases or decreases its
elevation by a height of 5 feet or more at any point following the
completion of grading;
4- diversion of rainwater runoff from an area 15,000 sq. ft. or larger;
5- blockage or alteration of a waterway or drainage way that has a
capacity of greater than two cubic feet per second;
6- repair of earth material slides involving 300 or more cubic yards of earth

7- clearing of an area one acre in size or larger OR clearing of an area
greater than 7,500 square feet with an average slope exceeding 5-to-1
(20 percent);
8- excavation for the installation, removal, or repair of any underground
storage tank. Exceptions are outlined in the Hayward Municipal Code.
