cable, to the general plan for the development of the District.
The said Commission is authorized to require to be preserved
on any plat a continuity of width, name, parking, building
line with relation to its general plan.

The Commission is hereby given authority to establish grades
for all streets, roads and sidewalks within the District, in-

any state, municipal or county officer or employee or any pri-

provide for the proper arrangement of streets in relation to
other existing and planned streets and to the Commission's
general plan, for adequate and convenient open spaces for
traffic, utilities, access of fire-fighting apparatus, recreation,
light and air, and for the avoidance of congestion of population,
including minimum width and area of lots.

Such regulations may include provisions as to the extent and
manner in which streets and other ways, curbs, gutters, and
