After approval, the County can hold a pre -construction conference. Applicants must complete the request for a pre -
construction conference form. The form identifies the contractor and responsible land disturber, and the fee
remaining to be paid. This will be checked by county staff, and upon approval, a pre -construction conference will be
scheduled with the County inspector. At the pre -construction conference, should everything proceed satisfactorily,
grading permit will be issued by the County so that work may begin.
County forms can be found on the county website forms center under engineering;
