(a) Factors for Development .— In view of the provisions of the Constitution respecting the establishment of the seat of the National Government, the duties it imposed on Congress in connection with establishing the seat of the National Government, and the solicitude shown and the efforts exerted by President Washington in the planning and development of the Capital City, the development should proceed along the lines of good order, good taste, and with due regard to the public interests involved, and a reasonable degree of control should be exercised over the architecture of private or semipublic buildings adjacent to public buildings and grounds of major importance. (b) Submission of Application to Commission of Fine Arts .— The Mayor of the District of Columbia shall submit to the Commission of Fine Arts an application for a permit to erect or alter any building, a part of which fronts or abuts on the grounds of the Capitol, the grounds of the White House, the part of Pennsylvania Avenue extending from the Capitol to the White House, Lafayette Park, Rock Creek Park, the Zoological Park, the Rock Creek and Potomac Parkway, Potomac Park, or The Mall Park System and public buildings adjacent to the System, or abuts on any street bordering any of those grounds or parks, so far as the plans relate to height and appearance, color, and texture of the materials of exterior construction.
