Conditions

The Planning and Zoning Commission or Board of County Commissioners is authorized to grant such exceptions from these site plan approval standards as may be reasonable and within the general purpose and intent of this Division, if literal enforcement of the standards is impractical or will exact undue hardship because of peculiar conditions pertaining to the land in question.


Effect of Approval

No structure or land use requiring site plan approval shall be commenced until the Planning and Zoning Commission or Board of County Commissioners has approved the site plan in accordance with this Division. The Board or Commission shall endorse its approval on a copy of the site plan and shall immediately file it in the office of the Planning Coordinator.

Expiration

A site plan approval shall expire if the use is not commenced and diligently pursued within one year of the date of approval. The Planning Coordinator may extend this time limit one additional year when the development permitted by the site plan approval has been delayed due to circumstances beyond the applicant’s control.
