Philip Darling, 62, a Transportation Department planning official, died of leukemia Thursday at Johns Hopkins Hospital in Baltimore.
He had been with the department since 1968, and was community planner in the office of environmental policy of the Federal Highway Administration at the time of his death.
Mr. Darling also taught a course in urban transportation planning at the Howard University Graduate School during 1970-72.
Born in Brooklyn, he grew up in Pleasantville, N.Y. He received a civil engineering degree from Yale University and a master's degree in city planning from Massachusetts Institute of Technology.
Mr. Darling had been a project planner with the U.S. Housing Authority, concerned mainly with housing projects in New England, before and after World War II, when he served with the Army in the Pacific.
In 1948, he became director of development with the Housing Authority of Baltimore City. When the Batimore Urban Renewal and Housing Agency was formed in 1957, he was named director of development.
A year later, Mr. Darling was appointed director of the planning commission and the department of planning for the city of Baltimore. In 1965, he became the city's first development coordinator.
He was a past president of the Baltimore chapter of the American Institute of planners and a member of the American Society of Civil Engineers, the National Association of Housing and Redevelopment Officials, the National Housing Conference and Common Cause.
He is survived by his wife, Ilse Museller Darling, of the home in Annapolis; two children, Christopher, of Seattle, and Kate, of Fairbanks, Alaska; two brothers, Paul, of Portland, Maine, and Dudley, of Scarborought, N.Y., and a sister, Helen Johnson, of New York City.
The family suggests that expressions of sympathy may be in the form of contributions to the scholarship fund of the American. Institute of Planners in Baltimore.
