"Front Yard" means a yard extending between side lot lines across the front of a lot. On a Corner Lot, the owner may elect either street frontage as the front yard.
Depth of required front yards shall be measured at right angles to a straight line joining the foremost points of the side lot lines. The foremost point of the side lot line, in the case of rounded property corners at street intersections, shall be assumed to be the point at which the side and front lot lines would have met without such rounding.
