Where the Planning Commission finds in any particular or specific case, due to unusual topography or other exceptional conditions not common to other areas similarly situated, that extraordinary or undue hardships may result from strict compliance with any requirement of these Regulations, it may recommend that Council relax such requirement to the extent deemed just and proper, so as to relieve such difficulty or hardship, provided that such relief will not have the effect of nullifying or impairing the intent and purpose of these Regulations, the Street Plan or the Zoning Code or jeopardize the safety or health of the community. Modifications thus granted, with the reasons therefor, shall be entered in the minutes of the Commission and submitted to Council for final approval.
