VI. BUILDING DESIGN CHECKLIST: (this is a tummsry only, refer to Ord. no.//O-95-1013)
The Collewille zoning ordinance requires building facades of new construction to contain design comple~ity features that
achieve a certain minimum score for each type of zoning dis~ct (see Section G below for required scores). This checklist
is in the format of a worksheet, since the ordinance requires computations of the building facades. Please show all
calculations and the final result at the bottom of this page at Section F. If not familiar with this ordinance, applicant is
encouraged to trlilize the 'Co~ Bu/k~g Des/gn Booklet' available at the Community Development Department.
