(1) Legislative Findings. The Council finds that:
(a) The Logan Square community has historically been a mixed residential, institutional, business and cultural center in the City of Philadelphia;

(b) Major public and private investments have been made and continue to be made to protect and maintain the mixed use nature, economic viability, aesthetics and historic character of this area of the City;

(c) The current provisions of the Zoning Code permit buildings of a height which may be considered as being incompatible with the general character of the area to the north of Arch street;

(d) This area is important to the historic, cultural and commercial vitality of Center City Philadelphia and buildings the height of which is out of character with the remainder of the community could have a negative impact upon this area;

(e) It is in the best interest of the property owners, business operators, residents and the City of Philadelphia that this area continues to prosper;
