The Olney master plan, recently approved by the Montgomery County Council, is one of many studies being prepared by the Maryland-National Capital Parks and Planning Commission.More than a dozen Montgomery communities are involved in some aspect of the planning process.

Takoma Park: A municipal plan for the entire city is under study. A preliminary draft was published this year, with a hearing held in April.The plan will require approval of both the Montgomery and Prince George's county Councils. It is expected to go before the Montgomery County Council later this summer.

Silver Spring: Planners are working on a plan aimed at revitalizing Silver Spring's central business district. A technical study, funded by the U.S. Urban Mass Transportation Administration, is examining private and public investment in publicly controlled sites near the Silver Spring Metro station. The project is scheduled to continue through next year.

West Silver Spring: A master plan for the area, adopted in 1971, is scheduled for review and updating. This is part of an effort by the county Office of Community Development to preserve moderately priced housing there.

Kensington-Wheaton and Kemp Mill: Planners are undertaking a study of areas around Forest Glen, Wheaton's central business district and Glenmont to examine development pressures resulting from the planned extension of Metro from Silver Spring. Work on the study is scheduled to begin this year in the University Boulevard corridor between Kensington and Four Corners near Colesville Road. The planning commission is investigating the possible rezoning of several land parcels along major roadways, as well as public services such as bus transportation for a population in the area that is both aging and declining in numbers.

Route 29: Planners are preparing final draft plans for Colesvlle, Fairland and White Oak for presentation to the County Council. Plans for the area attempt to contain strip commercial development as well as protect local streams.

Nobeck: Located at the southern end of the Olney master plan area, the Norbeck community has been designated a special study zone for the examination of degenerating housing.

Aspen Hill: Aspen Hill is expected to require study in the next few years to identify possible changes in the plan adopted in 1970. The plan may require amending as a result of extending Metro service to Glenmont.

Friendship Heights: Planners expect applications for commercial development in the business district area within the year. They will be studying development proposals, as well as the need for improved public facilities, such as parks, roads and transportation.

Bethesda: Planning commission staff will be working with Metro officials to coordinate transportation facilities in conjunction with the air rights building proposed for construction over the Metro station. public parking garage for the station and plan to design traffic control measures for several intersections.

Gaithersburg: Staffs from the county planning board and the City of Gaithersburg are examining ways to work together on a master plan for the area.
