Louis Park, 67, a retired government civil engineer and former area builder who was active in Jewish and Zionist organizations, died Thursday at Washington Hospital Center. He had a heart ailment.

Mr. Park began as a civil engineer in the mid-1930s with the old National Capital Housing Authority. In 1944, he was drafted into the Army, and a short time later, received a commission as a Navy lieutenant. He served as a seaplane tender navigator in Europe, Africa and the Middle East and in the Atlantic and Pacific theaters.

Following his military discharge in 1946, he founded Parkview Builders in Montgomery County. After dissolving the business in 1955, he worked as an engineer for the Department of the Army and for the old Urban Renewal Administration in Philadelphia.

From 1964 until his retirement in 1973, Mr. Park was an engineer for the Department of the Navy.

Born and reared in Washington, he graduated from old Central High School in 1930. In 1935, he earned a bachelor's degree in engineering from the University of Maryland, where he was active in the Reserve Officers' Training Corps (ROTC).

Mr. Park lived in Rockville and was active in the Men's Club of B'Nai Israel Congregation there. He was a member of the Jewish War Veterans, B'nai B'rith and the Zionist Organization of America.

His marriage to Ruth Gross ended in divorce.

Survivors include a son, Joseph D., of Silver Spring; two daughters, Bonnie Brodsky of Rockville, and Judith Dunning of Los Alamos, N.H.; two sisters, Frances Jones of Chevy Chase, and Shirley Goldpaint of Philadelphia, and six grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Louis Park Memorial Fund at B'Nai Israel Congregation in Rockville.
