WJLA (Channel 7) may be the television station that's "On Your Side," but some residents of Northwest Washington want to keep the local broadcaster out of their side of town.

It was bad enough, they say, when the station announced plans to move into new quarters in the Intelsat complex at Connecticut Avenue and Van Ness Street NW. Now WJLA wants to plant satellite dishes and garages for its news vans on Tilden Street on the border of the Cleveland Park historic district.

And WJLA isn't the one and only burgeoning television operation running afoul of neighbors. A few blocks away, residents in the Tenley Circle area off Wisconsin Avenue are gearing up to fight a move by WUSA (Channel 9) into a proposed five-story office building next to a controversial office-movie complex at 4000 Wisconsin Ave.

Today the National Capital Planning Commission is expected to vote on WJLA's plans for the Cleveland Park site, which is part of an Intelsat expansion involving about 150,000 square feet of office space that is scheduled to be ready for tenants in late 1988.

The commission staff has recommended approving WJLA's plan, but D.C. government officials have criticized the decision by Intelsat and the State Department to rent the space to the television station, contending that a foreign government or international organization would be a more appropriate tenant for the federally owned land.

Congress originally set aside federal land at the site for use by foreign governments and international organizations. Earlier this year, NCPC approved by the narrowest possible vote leasing space to WJLA under a provision permitting some commercial use there. Now come plans for satellite dishes and garages.

Area resident Rob Robson, board member of the nearby 3016 Tilden St. cooperative apartment complex, charged that the station is bullying the neighborhood.

"If I were {WJLA}, I'd be trying to be good neighbors. In fact, the opposite is happening. They're trying to railroad something through," he said. "I think they're going to find out that their railroad is derailed."

Both Intelsat and WJLA contend that the six satellite dishes on a hillside along Tilden Street and next to the Kuwaiti Embassy are vital to their operations and will not become the blight opponents fear.

"We have to have these kinds of antennas," said Intelsat spokesman Tony Trujillo.

Officals for WJLA could not be reached for comment.

But while Trujillo says that the international communications cooperative is "trying very diligently to be good neighbors" in the dispute, Robson and others claim they are victims of a bait-and-switch they say will create a traffic problem as well as an eyesore.

"It violates all zoning concepts. It violates all planning concepts," said D.C. Council member Jim Nathanson (D-Ward 3), who maintains that only banks, travel agencies and other such "local service" businesses were envisioned for the Intelsat complex.

Nathanson said he is less bothered by construction plans for 4100 Wisconsin Ave., where WUSA, now straining its 45-year-old facilities on Brandywine Street NW, would lease a major part of a proposed five-story office building.

How citizens will react is another matter.

Construction of a office-movie complex only a block away touched off an antidevelopment protest last year and community residents are still fighting a proposed road for the project that is adjacent to nearby Glover-Archbold Park. WUSA has incorporated the road in its plans.

Ronald Townsend, president and general manager of the station, declined to comment on WUSA's plans.
