The Newtown Inland Wetlands Commission is taking up an application tonight on the proposed mixed-use Hunters Ridge complex.  A public hearing on the application by 79 Church Hill Road, LLC will be held at 7:30pm.  The Planning and Zoning Commission will hold a public hearing tomorrow on the proposals.  The project would sit on 35-acres of undeveloped land near the Exit 10 interchange ramps.  224 rental apartments in 6 buildings, with related amenities, are planned.  20 percent, or 45 units, would be designated as affordable to help meet a state mandate to increase its stock of affordable housing.  Two two-story buildings are planned for retail, medical and restaurant space.
