Loudoun County YMCA and Sterling community leaders have announced plans for a new Sterling/Dulles area YMCA that would be the county's first to provide an indoor swimming pool and a full-service child care center.

The opening of the county's first YMCA branch outside the Leesburg headquarters is contingent on community donations. To open in 1992, the YMCA and its organizing committee of community leaders need at least 500 charter memberships, each costing $150. If that effort is successful, the YMCA will conduct a $250,000 fund-raising campaign for equipment and supplies.

The new YMCA would be located in the still unconstructed Life Center on Glenn Drive, just south of Sterling Boulevard. The Life Center is part of the Trans Dulles Center, a project of Landstar Development Corp. The YMCA would lease space from Landstar. Landstar President Eric Wells is on the new YMCA's organizing committee and is also president of the Sterling Foundation, a community group formed to promote Sterling Park.

Landstar will host a community meeting for civic groups to get information on the new YMCA at 8 p.m. tonight at its offices at 105 Executive Dr., Suite 200. The organizing committee also meets there each Tuesday at 4 p.m.

The YMCA and organizing committee have planned a communitywide membership meeting at 5 p.m. Sept. 9 at the United Airlines Reservation Center on Davis Drive in Sterling. The committee hopes to sign up 1,000 charter members.

"We've been working for a year . . . talking to people in Sterling, trying to decide if {the new branch} could succeed," said Nancy Devine, executive director of the Loudoun YMCA. "The idea of having a family fitness center is something people seem to have really embraced."

She said advance membership fees will be refunded if the YMCA does not receive enough support to open the branch.

The organizing committee is chaired by Dennis Mitchell, the county's chief building inspector and a member of the Sterling Youth Soccer Association and the county's Parks and Recreation Advisory Board, and Steve Wilson, a principal with Dulles Investment and Development.

Mitchell said he is leading the project because Sterling lacks public facilities where entire families can go for recreation and fitness and he thinks the YMCA could fill that need. Sterling families also need more quality child care, he said.

Besides the indoor swimming pool and a child care center with space for 100 children, the YMCA would have a therapy pool, whirlpools and saunas, locker rooms, exercise and weight rooms and space for classes and meetings.

While such facilities are common to YMCA branches nationwide, it would be a first for Loudoun.

Loudoun YMCA headquarters in Leesburg has an exercise room and space for meetings, programs and preschool, but activities such as swimming take place at other facilities that allow use by the YMCA.

"In a sense this {Sterling branch} would be our first real Y facility," Devine said. "It's the first part of our overall strategy to have branches of this type around the county."

Devine said her agency, which has been in Loudoun County for six years, has been working with Landstar Development Corp. and Hughes Group Architects on design plans for the new branch.

The child care center would be located on one end of the building and the 25-yard, six-lane swimming pool on the other, with meeting rooms, and exercise, weight and gymnastic rooms in between. The Loudoun YMCA now has four full-time employees, including Devine. It would hire a branch manager and teachers for the child care center if the new branch is successful, Devine said.
