The Artery Organization Inc., on orders from the Montgomery County Planning Board, started removing a loft unit this week from a town house that was partially obstructing a view of Lake Seneca for a group of residents of the Churchill Town subdivision near Germantown.

In a 4-0 vote, the board ruled last week that Artery, the developers of the 88-unit Willow Cove town house project on the shore of the lake, had built the town house six feet above the authorized height limit of 25 feet above Wanegarden Drive. The street separates the town house development and the residents' homes.

The board also prohibited Artery from building loft units on the tops of two other town houses.

"We're very pleased," said Maryellen Little, who moved into a Churchill Town home 18 months ago with her husband Don. The view from their screened deck is of a wall of town house roof tops.

"There were some other violations that were overlooked, but I don't think we'll appeal {the decision}," she said.

For the past 2 1/2 years, Churchill Town residents have met with Artery executives, Montgomery county planners and members of the Planning Board to try to resolve the issue, but weren't successful until the board met Oct. 22.

The residents said they knew when they bought their homes that the town houses were going to be built, but they said they were assured by Artery executives that the homes would not "substantially" obstruct their view of Lake Seneca, the trees in Black Hills Regional Park and Sugarloaf Mountain.

Artery workers are expected to have the loft removed within a week, the company said.

"It just goes to show you that if you do get involved, take some of the right steps and keep after it, you can get things done," said Michael Schreiber, one of the residents who has been fighting to keep the view. "And we did it without a lawyer." California builders are vociferous in their view that local governments are largely responsible for the high cost of housing through imposition of various fees and requirements, according to a new survey.

The survey said the state's builders estimate that the additional cost totals nearly $19,000 per house.

The National Association of Home Builders, which conducted the survey, said that development fees account for nearly two-thirds of the total, with the balance stemming from requirements to set aside land for various public purposes.

The California builders said that development fees have risen from $5,792 per single-family house in 1983 to $11,807 today.

"Obviously there is a great need to improve our public infrastructure and through public and private means," said Dale Stuard, president-elect of the NAHB and a Newport Beach builder. "Our concern is over the increasing tendency of communities to assess charges against new home buyers that are used to pay for repairs for the existing infrastructure that ought to be financed out of general tax revenues."
