In the R-6 District, reversed corner lots shall meet the front yard building setback line on that side of the lot that this chapter defines as the front and shall provide a setback on the side that abuts the front yard of an abutting lot equivalent to 1/2 of the front yard setback requirement of the abutting lot. In the R-6 District, lots that are not reversed corner lots shall meet the front yard building setback requirement on that side of the lot that this chapter defines as the front and shall be required to meet the side yard requirements on both side yards.
On the certain streets named in this section, special building lines shall be and hereby are established which are to be measured from the center line of the street in each case, respectively. When any other building line established by this chapter is deeper than the special building line established in this section, said first mentioned building line shall apply, and where the special building line is deeper, it shall apply. Along the streets named in this section, no building shall be hereafter erected or altered so as to place its front or side street wall nearer to the present center of the street than the dimension given in the following table for each street, respectively:
