National Park Service Planning, 1945-1989 and undated

Series III consists of material related to projects conducted by McCann as a park planner with the National Park Service during the 1970s and 1980s. The majority of McCann's working papers comprise this series. Projects in this series encompass a broad range of sites in Washington, DC; New York; Ohio; Georgia; and California. The projects include Ellis Island, Cuyahoga Valley National Recreation Area, Gateway National Recreation Area, Santa Monica Mountains National Recreation Area, Glen Echo Park, Lowell National Cultural Park, Warm Springs, and the Women's Rights National Historic Park. The material in this series consists of correspondence and internal National Park Service memos, master plans, reports, newspaper clippings, and essay drafts. Of particular interest is a folder of copies of the original deed and maps of President Roosevelt's Warm Springs estate in Georgia; an extensive history of Seneca Falls, New York, created during the planning of the Women's Rights National Historical Park; and a study on the preservation of Ellis Island that notes its condition before and after restoration.

Series III also documents McCann's work in urban park planning. He took an interest in urban parks throughout his career in the National Park Service, eventually becoming the Assistant Director of Urban Park Programs. Series III contains information on urban park programs he developed, including Summer in the Parks, a program conducted in Washington, DC in response to the riots there in 1968. Files concerning McCann's role in the drafting of two significant urban recreation plans for the Department of Housing and Urban Development and the Department of the Interior are also included in this section of Series III.

The arrangement is alphabetical by project name or topic. Photographs and slides originally included in this series have been placed in Series IV and V.
