On any corner lot on which a front and side yard is required, no wall, fence, sign, structure, or any plant growth which obstructs sight lines at elevations between 2 feet and 6 feet above the crown of the adjacent roadway shall be placed or maintained within a triangle formed by measuring from the point of intersection of the front and exterior lot lines a distance of 30 feet along said front and side lot lines and connecting the points so established form a sight triangle on the area of the lot adjacent to the street intersection.

(5) Location of attached private garage. An attached or detached private garage which faces on a street shall not be located closer than 25 feet to the street easement line.
