The roadway edge at street intersections shall be rounded by a tangential arc with a <br />minimum radius as specified in Table A Street Grade and Intersection Standards. The right- <br />of-way radii at intersections shall be substantially concentric with the edge of the roadway. <br /> 7. Where appropriate, the Planning Commission may require additional traffic lanes to <br />facilitate vehicular turning movements at existing or proposed street intersections within or <br />bordering subdivision plans. <br />8. Clearly marked crosswalks shall be provided at all intersections when sidewalks or <br />pedestrian easements are provided in a development. Crosswalks may also be required by <br />the Planning Commission at other locations to promote the convenience and safety of <br />pedestrian traffic. The design of crosswalks and the materials used shall be consistent with <br />other crosswalks in the area. <br />(j) Sight Distance at Intersections. <br />1. Proper sight distance shall be provided at all new street and all new access drive <br />intersections in accordance with the latest edition of the American Association of State <br />Highway and Transportation Officers (AASHTO) A Policy on Geometric Design of Highways <br />and Streets. Sufficient design and plan information shall be submitted with the plan <br />application proving that this minimum standard will be achieved and such design <br />information shall be performed by a professional registered in North Dakota to perform <br />such design work. <br />2. At all intersections where stop signs or other stop control devices are not proposed, sight <br />triangle easements or dedicated right-of-way shall be required and shall include the area on <br />each street corner that is bounded by the line which connects the sight or "connecting" <br />points located on each of the right-of-way lines of the intersecting street. The planting of <br />trees or other plantings or the location of structures exceeding thirty (30) inches in height <br />that would obstruct the clear sight across the area of the easements or right-of-way shall be <br />prohibited; and a public right-of-entry shall be reserved for the purpose of removing any <br />object, material or otherwise, that obstructs the clear sight. The distances shown in Figure X. <br />Sight Triangles between the connecting points and the intersection of the right-of-way lines <br />shall be required. <br />Figure X. Sight Triangles
