Commissioners gave preliminary/final approval for Faith Evangelical Free Church at 6528 Hamilton Blvd. to replace some temporary buildings with a three-story Children & Student Building addition that will have a total square footage of 40,500 feet.

It will be built near Mill Creek Road behind the existing sanctuary. If the congregation approves the project early next year, a fund-raising stewardship campaign will begin. Officials hope construction will start in 2013. The building will take up to 12 months to complete. Eventually, the congregation also hopes to build a new sanctuary, said township planning director Sara Pandl.

Commissioners agreed to hire township-based Hanover Engineering Associates, Inc., to serve as its “conflict engineer” on those rare occasions when Keystone Consulting Engineers, which provides the township engineer, would be in the position of having to review its own development projects.

Lower Macungie intends to also hire a “conflict solicitor” if the township solicitor also might be in a potential conflict of interest situation.
