The PADC asked Congress to appropriate $111 million for land acquisition, landscaping, and other needs. The plan saw yet further revisions during this period, reducing the size of the buildings along the north side of the avenue, reducing the size of the proposed Western Plaza, and allowing for greater variety of buildings and usage. In March 1977, Congress provided the first $29 million in funding and borrowing authority for the PADC to begin its work. Landscaping and widening of the sidewalks began in the fall of 1977, and rerouting of traffic began as construction on the new Western Plaza (renamed to Freedom Plaza in 1988) was undertaken. The following year, staff began working on two development prospectuses: one for the Willard and adjacent properties, and the other for the properties surrounding the National Press Building.
