The Department of Neighborhood Empowerment shall complete development of the Plan and present the Plan and all necessary Regulations for a system of neighborhood councils to the Council and Mayor within one year of the establishment of the department and commission. The Council shall consider the Regulations, and within six months after presentation of the Plan to Council may adopt ordinances to implement the Regulations as proposed, or as modified by the Council consistent with the requirements of the Plan set forth in Section 904. If implementing ordinances are not adopted within this time period, the Regulations shall become effective, and to the extent not inconsistent with law shall be binding upon all City departments and offices.
