A. 
Council may grant a modification or waiver of the requirements of one or more provisions of this chapter if the literal enforcement will exact undue hardship because of peculiar conditions pertaining to the land in question, provided that such modification will not be contrary to the public interest and that the purpose and intent of the chapter is observed.
B. 
Council may grant a request for a modification of the requirements of this chapter where the developer or applicant demonstrates that the performance objectives of the subject provision are met or exceeded by the modification proposed.
All requests for a modification shall be in writing and shall accompany and be a part of the application for development. The request shall state in full the grounds and facts of unreasonableness or hardship on which the request is based, the provision or provisions of the ordinance involved and the minimum modification necessary.
Where an alternative to adopted chapter requirements is proposed, absent the claim of a hardship, the applicant shall submit sufficient evidence to substantiate the equal or greater performance of the proposed alternative versus that required by this chapter.
In addition to the above waivers, Council may waive the requirement for sidewalks in § 240-60 where the existing grade adjoining the street is 8% or greater and cannot reasonably be altered; where the average lot frontage directly adjoining a subject street is 200 feet or more and no pedestrian connection of the subject street to adjoining planned streets necessitates sidewalks; or in accordance with any other standard of this part.
