The D.C. Office of Planning, criticized by community groups for not having enough citizen participation in drafting the proposed comprehensive land use plan, has appointed three advisory committees composed of neighborhood and professional representatives to help prepare the final draft.

City officials also have announced a series of public hearings on the proposed plan that will be held during the month of April.

John (Skip) McKoy, director of the city's planning office, has said that the city is making every effort to solicit public comments.

Community groups in the past have criticized Mayor Marion Barry for taking too long to finish the plan, which would set guidelines for commercial and residential growth in Washington for the next 20 years.

Now, these same critics, concerned in part that the proposal contains inadequate safeguards against further commercial encroachment into residential areas, are asking that Barry postpone sending the draft to the council by the present July 1 deadline. Last Saturday, a majority of the city council members asked Barry to delay until at least next fall sending the proposal to the council.

The draft plan, released last October, would restrict most future commercial growth to the downtown core and designated neighborhood centers, confine most industrial construction to the New York Avenue NE corridor, and regulate land use by the city, federal government and private firms along the city's waterfront.

The planning office has also been holding a series of community workshops on the plan.

The remaining workshops are:

Wards One and Three, 6 p.m. today at the office of planning, 420 Seventh St. NW.

Wards Four and Five, Thursday at 6 p.m. at the office of planning, 420 Seventh St. NW.
