G. Revision to Approved Plans.
1. By Subdivider. Requests by the subdivider for revisions to the approved plans appearing necessary or desirable during construction shall be submitted in writing to the Department of Public Works or authorized representative and shall be accompanied by revised drawings showing the proposed revision.

Upon receipt of the initialized originals, the subdivider shall immediately transmit revised drawings to the Department of Public Works. Construction of all or any portion of the improvements may be stopped by the Department of Public Works until revised drawings have been submitted.
