No certificate of occupancy shall be issued for any project for which landscaping is required pursuant to Section 25-22-10, or as required by the planning commission, until all landscaping and improvements shown on the approved plans have been completed. The building official may issue a temporary certificate of occupancy, where completion of the landscaping work is delayed because of adverse weather or the season of the year, upon execution of an agreement with the city and providing a cash deposit or letter of credit in an amount equal to the cost of completing the work. If landscaping differs from that shown on the approved plans, as built plans shall be submitted and approved prior to occupancy. (Amended during the March 2009 supplement.)
