"The board felt it was important to provide for an oasis of green space," Christopher said.
The decision met resistance from supervisors Christopher Firme and John Gorman, who voted against the agreement based on their desire that the township receive more land atop the hill.
"I want those other two lots," Firme said.
The decision to accept the amended agreement ends months of debate about the top of the hill, which Christopher called an "overlook area."
In a separate decision, the supervisors unanimously accepted a roadway agreement with developer B2M2 for 122 single-family houses on Orchard Road on the same night they rezoned 3.74 acres of the proposed development from commercial to medium-density residential.
The agreement requires that B2M2 build a 1,000-foot section of Washington Township Boulevard between Pa. 997 and Pa. 316, Christopher said. It also provides the developer a fall-back position if the board does not approve preliminary land development plans, he said.
"The agreement specifies that if, for whatever reason, they do not get their plans approved in 120 days, they can back out, but they have to pay the township's fees to rezone the 3.74 acres," he said.
Washington Township Boulevard is a $14.3 million traffic relief route being built in phases north of the Borough of Waynesboro.
The section of Washington Township Boulevard from Pa. 997 to Pa. 316 was supposed to be the final phase of a fully planned five-step process expected to last until 2014. However, the B2M2 development would expedite the road work in that area.
The township has tentative plans to one day connect Washington Township Boulevard to Pa. 16 west of Waynesboro.
