BUFFALO TWP — Homes in the Twin Oaks housing plan should be sprouting along Route 228 this spring.

Steven Victor, landscape architect for the Sewickley firm Victor-Wetzel Associates, which designed the plan for the developers, the John Allen family, said the plan’s 98 single-family homes would be constructed over three phases.

Victor said each phase, which would be completed over three years on 43 acres, would be divided into roughly a third of the total 98. Construction of the first phase would begin in April.

He said buyers would have the option of selecting a one- or two-floor house.

The development includes three parklets, a tot lot and two walking trails.

Victor said he expects no problem meeting the necessary approvals from Buffalo and the state Department of Environmental Protection to start moving dirt in the spring, but they have to be granted first.

The township supervisors earlier this month approved a conditional use for the plan.

The approval is contingent on the following seven conditions being met:

Convert the intersection of Route 228 and Hepler Road into a 90-degree angle as well as widen Hepler by 3 feet

Provide recreational amenities and walkways as well as paying a fee in lieu of further recreational amenities of $1,500 per lot

Perform traffic studies related to future residential development

Extend utilities from existing lines to the development

Design any required road improvements

Provide a $20,000 deposit in escrow for all engineering and legal review fees pertaining to the development and replenish the fund whenever it drops below $10,000

Design and construct improvements on future planned residential developments at the site.

The Allens plan to eventually develop more of the site, which totals 160 acres. Victor said that construction would be closer to Route 356.

The next step for the initial plan of 98 homes goes before the township planing commission at its Jan. 4 meeting, which starts at 7:30 p.m.

There would be a subsequent vote on the final approval by the township supervisors later.
