The National Capital Planning Commission may make a report and recommendation to the Zoning Commission of the District of Columbia, as provided in section 5 of the Act of June 20, 1938 (ch. 534, 52 Stat. 798), on the relation, conformity, or consistency of proposed amendments of the zoning regulations and maps with the comprehensive plan for the National Capital. The Planning Commission may also submit to the Zoning Commission proposed amendments or general revisions to the zoning regulations or the zoning map for the District of Columbia.

When requested by an authorized representative of the Planning Commission, the Zoning Commission may recess for a reasonable period of time any public hearing it is holding to consider a proposed amendment to the zoning regulations or map so that the Planning Commission may have an opportunity to present to the Zoning Commission an additional report on the proposed amendment.
