The Director of Planning may not approve any engineering correction for a site that has not had building permits issued. A revised final development plan showing all changes proposed under this section must be submitted to the Director of Planning, with these changes indicated by marked-up or red-lined exhibit of plans. The revised final development plan proposed under this section must be reviewed and approved or denied by the Director of Planning within 15 days. A new final development plan, reflecting the changes approved under this section, must be filed with the Department of Planning, noting the date of the changes. Ord. 16-581
