The D.C. City Council yesterday delivered to a U.S. grand jury records subpoenaed Nov. 19 in connection with a two-year-old investigation of the now-defunct Youth Pride, Inc. and its executive director, Mary Treadwell.

Twelve former and present members of the council, including Mayor Marion Barry, Treadwell's former husband and a cofounder of Pride, were ordered to turn over any records they kept regarding a city trash-can advertising franchise awarded to Pride Environmental Services, Inc. (PES), a spinoff of Youth Pride.

The subpoenas also covered records related to a 1978 plan to salvage the failing trash-can operation by broadening the contract to include another exclusive franchise for PES -- this one to erect 500 bus shelters and sell advertising space on them.

That proposal was shelved in June 1978, after Council member Wilhelminia J. Rolark (D-Ward 8), a principal sponsor of the proposal and then chairman of the Council's Committee on Employment and Economic Development, withdrew her support.

Rolark furnished the grand jury with two loose--leaf notebooks of material from her committee's hearings on the bus shelter plan. Council member Jerry A. Moore Jr. (R-At Large), chairman of another committee that reviewed the proposal, furnished eight thick files of material. Council member John A. Wilson (D-Ward 2) also supplied several files.

The two-year investigation stems from published allegations that Treadwell and two associates of P.I. Properties, Inc., a real estate spinoff of Pride, stole, diverted and misappropriated $600,000 from the federal government and low-income tenants at the Clifton Terrace Apartments in Northwest Washington between 1974 and 1978. Treadwell has denied any wrongdoing.
