The Office of Urban Conservation was created in 1975 as part of the Department of Community Development (DCD). It was founded in an era of citizen protests against a proposed urban renewal program that would have demolished Pioneer Square and Pike Place Market. The office’s mandate was to coordinate Seattle’s historic preservation programs and administer the city’s landmark boards and historic districts. When DCD was abolished in 1992, the office became the Historic Preservation Program in the Department of Neighborhoods.

From 1852 onward, Pioneer Square was the center of Seattle’s commercial activity. The Great Fire of 1889 destroyed 25 blocks of downtown, but the city immediately began rebuilding, using fire-resistant stone and brick. The neighborhood flourished during the Alaska gold rush, but as the central business core began to move northward, Pioneer Square became host to rough taverns and seedy hotels. A city plan to raze the district in the 1960s generated a grass roots preservation movement led by architects Ralph Anderson and Victor Steinbrueck. In 1970 they succeeded in having the neighborhood designated as a national historic district as well as Seattle’s first preservation district.

The Pioneer Square Historic Preservation Board was instituted in 1971, and the Pioneer Square Special Review District Board in 1974. The two boards began holding joint meetings in October 1979, and continued this practice until September 1981 when they were consolidated as the Pioneer Square Preservation Board. The Office of Urban Conservation, and later the Historic Preservation Program, provided staffing to the boards. The Architectural Review Committee was a Board subcommittee.

The minutes report on issues discussed, tasks assigned, and actions taken, and include lists of board members and Office of Urban Conservation staff present. Board business primarily concerned consideration of applications for approval of architectural modifications and signage in the District.
