reduction of lighting standards in sensitive environ-
mental habitats and Other design modifications consistent with the conditions and intent of this sect ion.
C. Major design standard variances may include, but not be
limited to: street width, sidewalk meandering or deletions, horizontal alignments, environmental issues,
