Thereafter, when that applicant submits plans designated "standardized plan" for review, the applicant shall receive a minimal comparison plan review, along with a review of a site specific plot plan, including grading and drainage.

After the initial construction plan is standardized, the standardized plan review fee for resubmittals shall be ten percent of the building permit fee. If applicable, grading or other required plan review fees shall be in addition to the standardized plan review fee. If the plans are altered, or the building site or soils reports require redesign, additional plan review fees will become applicable or the plan may be required to be re-standardized.
