Two new proposed developments--one in the Lansdowne area on Route 7 and the other on Evergreen Mills Road--could add more than 2,600 homes to Loudoun County.

Lansdowne Community Development LLC wants to build 2,267 single-family houses and town houses on 1,090 acres at Route 7 and Riverside Parkway. The homes will range from 2,200-square-foot town houses with one-car garages to estate homes, said Rick Showalter, the company's director of marketing. Rezoning is not required, and construction would start in 2001.

Terrabrook, the company that built Broadlands, wants to build 430 units--single-family houses and town houses--on 1,295 acres east of Evergreen Mills Road (Route 621) near Leesburg. Terrabrook executives say they will submit a rezoning request for part of the land--now zoned for one unit per three acres--to create a rural village, which allows for a mixed use of residential, small retail and office space. Construction would start in 2001.

Tom D'Alesandro, general manager at Terrabrook's eastern region in Reston, said the village area would have a travel agency, doctor's offices, a hardware store and a bank. Terrabrook is also planning to ask for a special exception that would allow a golf course, a rural retreat center, equestrian facility and/or a vineyard.

Julie Pastor, Loudoun County's planning director, said about 80 percent of the land would remain in open space, under the rural village zoning guidelines. But she said property taxes from the development still will not pay for services for the new residents it brings.

Lansdowne Community Development purchased its property near Loudoun Hospital Center for $53 million from Xerox Realty Corp., the developers of the Lansdowne Golf Club & Resort. Company officials said a portion of the deal remains to be settled in April.

The land, which is mostly zoned for three houses per acre, is bordered by the Potomac River to the north, Route 7 to the south, the Potomac Station residential community to the west and the 205-acre Lansdowne Golf Club & Resort and undeveloped commercial parcels to the east. Goose Creek crosses a portion of the site.

The development company comprises four developers--Centex Home Corp. of Dallas, John Laing Homes of Irving, Calif., Beazer Homes USA Inc. of Atlanta and Van Metre Homes of Burke. The four developers will have a lottery system to divide the units. About 165 acres will be devoted to a golf course, Showalter said.

"This is a great opportunity," Showalter said. "We think we've purchased the premier residential property in Loudoun County. We have a property that has a name identity right from day one.

"People know Lansdowne," he said. "They've played golf there. The hospital is there. It gives us the opportunity to take a prime piece of property and make it even better."

A proffer agreement requires Lansdowne Community Development to provide 55 acres for elementary and middle school sites. Funding for the elementary school was approved in a November bond referendum, and it is scheduled to open in fall 2001. The middle school is scheduled to open in 2002. The developers also will make improvements at the intersections of Routes 7 and 641 and Routes 7 and 659.

The Xerox tract initially was more than 2,200 acres. Xerox plans to turn 200 acres acres of it into commercial and retail development. It has sold about 400 acres in smaller parcels to Leisure World, the Lansdowne resort and the hospital. It is seeking to sell the remaining land.
