Any fence or wall erected on the property line and located to the rear of the minimum required front yard line, as determined by the provision of 8-401 shall not exceed eight (8) feet in height above the adjacent grade. No vehicles shall be parked and no fence, wall, screen, or view obstruction or foliage or hedges, frees, bushes, or shrubs are allowed to be erected, planted or maintained within the “intersection visibility triangle” so as to obstruct within the sight line at elevations between three (3) feet and eight (8) feet above the average street grade. Obstructions of this nature are declared to be a public traffic nuisance.
In connection with regulations provided herein, “intersection visibility triangle” means a triangle sight area, at all intersections where the streets, avenues, alleys and public or private drives, intersect. It includes that portion of public right-of-way and any corner lot in the triangular area formed by extending the curb lines of the intersecting streets to their imaginary point of intersection for the first point of the triangle, then proceeding back from this imaginary point of intersection fifteen (15) feet along the curb lines of the intersecting streets to establish the two (2) remaining points of the triangle. These points shall then be connected with imaginary lines, thereby forming a triangle. If there are no curbs existing, the triangular area shall be formed by extending the pavement edges to the imaginary point of intersection of the streets and then proceeding in the same manner described above.
Any fence, wall, screen, hedge, tree, bush, shrub, erected, planted or maintained in violation of these paragraphs shall be removed within ten (10) days upon written notice from the city to the owners of the affected or adjacent property.
