In C5-5, C6-8 and C6-9 Districts, the Board of Standards and Appeals may permit modifications of the applicable regulations in Sections 33-26 to 33-30, inclusive, relating to Rear Yard Regulations, or in Sections 33-41 to 33-45, inclusive, relating to Height and Setback Regulations.

The Board may grant such modifications upon consideration that the applicable height and setback or rear yard regulations cannot be complied with by some method feasible for the applicant to pursue because of size or irregular shape of the lot, size or irregular shape of the block, and width of streets. The Board shall also consider the characteristics of surrounding development.

The Board shall require, where appropriate, sufficient safeguards to ensure the free flow of pedestrian and vehicular traffic in the general area. The Board may prescribe additional appropriate conditions and safeguards to enhance the character of the surrounding area.
