Despite the concerns of about a dozen nearby residents, the Upper St. Clair Planning Commission voted 5-0 Thursday night in favor of a small subdivision plan on Morrow Road.

The owner of the land, Dr. Andrew Zahalsky of Peters Township, returned to the planning commission with a revised plan that went from seven lots down to six.

There's also three stormwater deteniton systems planned for the development—one system for the lot Zahalsky plans to build his home, one system for another two lots and another system for the rest of the lots.

Zahalsky also moved the road, to be called Treetop Lane, down 30 feet to optimize sight distance. The proposed road is to sit between Engelwood and Hidden Timber drives.

Neighbors said they are worried about stormwater detention. Township Engineer Ruthann Omer said the developer will not be allowed to cause anymore water runoff than there already is.

Director of Community Development Scott Brilhart said a traffic impact study will not be required because the plan only has six lots.

Zahalsky told neighbors he would be leaving as many exisiting trees as possible. He privately spoke with the residents after the meeting.
