MIDDLESEX TWP — The township’s third planned residential development has been approved by the township supervisors.

Architect Steven Victor, who represented developer Frank Kelly at Tuesday night’s supervisors meeting, asked the supervisors to give final approval to all three phases of the Blackhawk housing plan. The plan is slated to have 95 single-family homes on 72 acres near the intersection of Browns Hill and Leslie roads.

Victor said he decided to seek approval for all three phases instead of individually as is usually done so the entire site could excavated and graded.

Township manager Scot Fodi told Victor he had concerns about denuding a large area of land that would not have storm sewers or a sediment plan until the second and third phases are added, which could take years.

Supervisor Chairman Mike Spreng agreed.

“I didn’t have a problem with this until I saw it all opened up and no (runoff) control,” Spreng said.

But Victor said erosion control measures would be added, and the property would be seeded to prevent runoff issues. He said four detention ponds would be added to catch and slowly release stormwater into a creek.

Victor said grading the entire site would benefit residents of the first and second phases because their properties would not see runoff problems as the future phases were graded and excavated.

“It’s going to be better because it will be seeded and done,” Victor said.

He said a three-foot split-rail fence with mesh on the side facing the homes would surround the plan.

Victor received preliminary approval for the Blackhawk plan in November, when about 25 residents showed up to share their concerns at a public hearing.

The residents disagreed with Victor’s assertion that the plan would not decrease their property values. They also complained the density of the plan does not fit the neighborhood’s rural character.

Victor said in November that the residents would have the advantage of connecting to the Oakmont Water Authority line that the developer is bringing to the development. He said the developer also would pay $100,000 to bring a natural gas line to the site.

As they did in November, the supervisors voted unanimously on Tuesday to approve the Blackhawk plan.

Victor said construction on the Ryan Homes, which are expected to cost $300,000 to $350,000 each, could begin in July or August.
