Panel Member Named The Leesburg Town Council last week appointed planning commission member James Clem to fill the unexpired term of Jerry Pelkey, who has resigned because he is leaving the area.

Clem, a federal employe, said his work with the Leesburg volunteer fire company will play a role in his new post. "As president of the fire company for the last two years, I know how important it is that the town has adequate roads and water for all the new growth that's coming west. We can't legally stop development but we have to get in a posture to take care of our needs."

Clem said that sometimes development happens so fast that proper roads and adequate fire hydrants are not built to serve the emergency needs of new residents.

Clem will serve two years of the three-year term. He will resign his planning commission post and the council will begin the process of naming his replacement this month, officials said.

In other action, the council set Sept. 23 for a public hearing on whether the town should sell $10 million in general obligation bonds to build a municipal center, a parking complex, a public works building and a swimming pool and gymnasium at Ida Lee Rust Park.

The meeting will be held at 7:30 p.m. in the town hall on Loudoun Street.

Hillsboro Postmaster Hill-Tom market owner Martha Torlone will serve as Hillsboro's new contract postmaster.

Torlone will conduct post office business in her store, she said. Hillsboro's 125 residents, who have been without local postal service since postmaster Charlotte James died suddenly in April, will be able to conduct post office business six days a week from 5 a.m. to 8 p.m., which are store hours, as long as someone qualified is there to handle it, Torlone said.

The new post office could open as early as next week, she said. Since the old post office also doubled as a town council meeting place, the council still does not have a permanent home.

According to Torlone, the informal daily gathering of officials and residents that once took place in the old post office has continued in the store, and, she said, "I expect it will go on."

New Post Office Opens Hamilton's new and long-awaited post office opened this week, offering a larger building, expanded service and the first parking spaces Hamilton's postal customers have ever had.

According to temporary Postmaster Carol Ambers, the town has been using the same leased building for more than 50 years and officials have wanted a new post office for at least half that time.

"Customers had to park in the street and it was dangerous," Mayor H.L. Lowry said. James Lloyd, a former clerk at the Leesburg post office, will serve as postmaster in the new building. A grand opening will be held soon, Ambers said.

Farmers' Market Open Loudoun's new growers-only farmers' market, which opened recently on the parking lot of Northern Virginia Community College, is attracting up to 500 customers and a dozen participating farmers every week.

According to county agriculture development officer Helene Lepkowski, the public will see new state-designed signs on Rte. 7 directing them to the market, which will be open from 8:30 a.m. to 12:30 p.m. every Saturday until the end of October.

School Budget Chief The Loudoun County School Board last week named Prince William County senior budget analyst Barbara Anderson as Loudoun's first school budget director. The board acted after consultants hired in June to review the school budget process recommended that such a position be established. The 1987-88 school budget is $66 million.
