LOCATION -- Two miles east of the Capital Centre and the Central Avenue exit from the Capital Beltway.

RACIAL MAKEUP -- In flux but mixed, with numerous whites, some Asians and a slight majority of blacks. So far, about 170 single-family detached houses have been built, of almost 2,000 houses planned, with a wide variety of prices and construction styles.

DESCRIPTION -- Lake Arbor is a 1,000-plus-acre development centered on an 18-hole golf course and a 22-acre lake, which is bringing what developers call "executive housing" to a county that until recently was regarded as having little market for it. A typical house has four bedrooms, 2 1/2 baths, a two-car garage, a fireplace and fancy bathrooms. However, a wide range of housing is planned, including relatively expensive high-rise rental units, condominiums, town houses and five-bedroom, single-family detached dwellings. The country club has a restaurant, an Olympic-size pool and six tennis courts.

COST OF HOUSES -- Single-family house prices along the golf course vary from $135,000 to $219,000, with $170,000 to $180,000 most common. Town houses are planned to cost roughly $110,000, according to Gary S. Lachman of Community Holdings Corp., project director for Lake Arbor. Condominiums are expected in the range of $95,000 to $140,000. "Luxury rentals" are planned to range from $650 a month for a one-bedroom unit to more than $1,000 a month.

POPULATION -- Middle-level supervisors and executives and professionals such as accountants and doctors. Typically, both adults in the family work. Young children are common. As condominiums, town houses and rental units are built, more singles and relatively well-off office workers are likely to live there.

SAMPLE FAMILY -- Dr. Frederick Corder, 34, and Dr. Marilyn McPherson Corder, 33, are pediatricians and partners in Corder Children's Center, a practice with offices at Landover Mall and in Northwest Washington. Their daughter Adrienne, 7, is in second grade in a private school in the District, where her brother, Frederick II, is in kindergarten. Marilyn Corder grew up in the county, in Glenarden. She attended the University of Maryland and met her husband, who is from the Detroit area, at the Howard University medical school. Their four-bedroom Colonial overlooks the country club's 13th hole.
