On any through lot, the front yard shall be considered that frontage upon which the majority of the buildings in the same block front; but in case there has been no clearly defined building frontage established, the owner shall, when applying for a building permit, specify which lot line shall be considered the front lot line.

All front yards must face on a dedicated public street or on a private street approved by the Planning Board.

Where a building lot has frontage upon a street which on the master plan or official map of the City is contemplated for right-of-way widening, the required front yard area shall be measured from such proposed future right-of-way line.

Where an existing lot has an assigned street mailing address, any and all future subdivisions of that lot shall be required to locate the front lot line of all new lots created by subdivision on the same street as indicated in the official mailing address of the original parcel.

Wherein an existing lot is a corner lot as defined in this chapter, any future subdivision of that parcel of land shall be required to front new lots created by subdivision on the shorter street frontages bounding the limits of the City block in which the subject parcel is located.
