To ensure that the offer of 141 acres of parkland will not be retracted, the Leesburg Town Council will ask officials this week to draft state legislation that will allow the town to take the extension of Catoctin Circle off its comprehensive plan.

In June, Leesburg resident and businessman William Rust offered the park site to the town on the condition that no road ever bisect it.

However, the extension of Catoctin Circle, which has been in the town's land use plan for 20 years, would put the road through part of the park, located on the town's western boundary.

According to Town Manager Jeff Minor, the council is willing to leave the Catoctin Circle issue up to "future councils," rather than lose the town's first major park and recreation area.

In a traffic report to the council last week, an engineer from Gorove-Slade, a traffic consultant, suggested that a future extension of the road could include a two-lane rural section through the park, to be named Ida Lee after Rust's grandmother.

No development is planned on the proposed extension for another 15 years.

"By that time there may be other options available," Minor said.

Rust wants to convey the park to the town in three parcels within three years, the first one by Jan. 1. According to Minor, it will take five to 10 years to develop the park fully. Firm to Insure Lovettsville

Lovettsville officials hope to receive word this week that a Dallas insurance firm, which already insures several local jurisdictions, has agreed to write a personal liability policy for Lovettsville Town Council members.

Until the policy is written, Mayor J.R. Hummer said, he has asked the council to discontinue all work on the town's proposed zoning map and comprehensive plan, which has come under fire from some citizens.

The group is protesting several rezoning requests that would put commercial property across from the Lovettsville elementary school.

The parcels at issue belong to Hummer, his wife Grace, who is a council member, and Elaine Walker, another council member.

The council felt it needed an insurance policy when the group opposing the rezonings indicated it would sue if the rezonings are approved.

According to Hummer, two other rezonings have been put on hold until the issue is resolved.

"The people who requested them have been very patient and understanding," the mayor said. Round Hill Town Plan

An informational meeting was held this week with Loudoun County Supervisor James Brownell and Hank Romberg, chairmen of the Greater Round Hill Area Planning Council, to discuss a plan that outlines growth in the town and approximately 650 acres around the town for the next 15 years.

Interested persons who missed the meeting may review the plan at the town office and at the county planning department.

A study ordered by the General Assembly this year has concluded that the Springfield-Manassas area is one of four in Virginia that would be economically feasible sites for farmers' produce markets.

The study, conducted by the Virginia Department of Agriculture, said that of the 97 individual farmers and 25 farmers' groups who responded to a survey, nearly 90 percent said they favored a farmers' market as an alternative way to market crops.

According to an agriculture department spokesman, Virginia is the only state on the East Coast that does not have a state-sponsored wholesale farmers' market.

Although Virginia has the soil and climate conditions favorable to fruit and vegetable production, the state imports 85 percent of its produce, the spokesman said.

Some benefits to Manassas and the other designated areas, which include Roanoke-Salem, Norfolk-Hampton Roads and Richmond-Petersburg, would be about 250 new jobs, a $11 million increase in fruit and vegetable production and the potential for higher earnings for farmers because retailers would not have to import produce, the study said.

A committee of legislators and industry and state officials who supervised the study will hold a public hearing in Richmond on Dec. 10. Haymarket Security Offer

Ted Reuter , president of a security company in Haymarket, last week offered the town up to three security officers for around-the-clock protection, a temporary detention center, a police headquarters, a radio communications center and several other security services for half again as much as the town pays its lone police sergeant -- when it has one.

Sgt. Don Fasick resigned several weeks ago and the one square mile town of 325 residents has been relying on county police to fill the gap while officials hire a replacement.

Reuter made the offer, he said, because he lives in the town and wants to "prevent trouble."

Reuter said, "I'm not anticipating a shootout at Gossam's hardware store and there's no crime wave here. I just believe that we the people have a right to protect our children and our town."

The town sergeant is paid approximately $14,500 annually, according to clerk Dorothy Keller.

Although town attorney Turner Smith said that Haymarket must hire a police officer to keep its charter, Reuter believes it is legally possible to accept his offer as well.

The council directed Reuter to prepare a detailed program and present it to the council for study by the end of the year, Reuter said.

In other business, the council approved a cable TV franchise ordinance and began advertising for bids this week.

At least three companies that supply cable to other areas of the county have indicated an interest in submitting a bid, Keller says. Prince William Office Moves

*The Prince William County Litter Control Council, which is looking for volunteers, has moved from its Sudley Road address in Manassas to the old county building at 9250 Lee Ave., also in Manassas.

According to a spokesman, the council needs volunteers to help in education, law enforcement and clean-up planning as well as for its speakers bureau.

The only qualification necessary to serve the council, the spokesman said, is "an interest in making Prince William County a safe and more beautiful place to live."
