All corner lots must meet front yard requirements on all yards abutting public street right-of-way. Any lot that is separated from public street right-of-way by a portion of an adjacent lot or a parcel that is neither a lot nor a nonconforming lot under this chapter and, but for this separation would be a corner lot, must also meet front yard requirements on all yards abutting public street right-of-way and all yards that otherwise would be abutting public street right-of-way but for separation by such nonconforming lot.
