Subd. 2. Railroads and Limited Access Railroad rights-of-way and limited access roadways where as to affect the subdivision of adjoining lands shall be follows: § 11. 33 Roadways. r so located treated as A. In residential districts a buffer strip at least 25 feet in depth in addition to the normal depth of the lot required in the district shall be provided adjacent to the railroad right-of-way or limited access roadway. B. In districts zoned for business, commercial, or industrial uses the nearest street extending parallel or approximately parallel to the railroad shall be at a sufficient distance therefrom to ensure suitable depth for commercial or industrial sites. C. Streets parallel to the railroad when intersecting a street which crosses the railroad at grade shall be -at a distance of at least 150 feet from the railroad right-of-way. Such distance shall be determined with due consideration of the minimum distance required for future separation of grades by means of appropriate approach gradients. D. Streets crossing the railroads shall be avoided. Subd. 3. Intersections. A. Streets shall be laid out so as to intersect as nearly as possible at right angles. A proposed intersection of two (2) new streets at an angle or less than seventy-five (75) degrees shall not be acceptable. An oblique street should be curved approaching an intersection and should be approximately at right angles for at least one hundred (100) feet therefrom. Not more than two ( 2) streets shall intersect at any one point unless specifically approved by the City. B. Proposed new intersections along one side of an existing stre,et shall coincide with any existing intersections on the opposite side of such street. Intersection jogs with center- line offsets of less than 150 feet shall not be permitted, except where the intersected street has separated dual drives without median breaks at either intersection. Where streets intersect major streets, their alignment shall be continuous. Intersection· of arterial roadways shall be at least eight hundred (800) feet apart. C. Minimum curb radius at the intersection of two (2) local streets shall be at least fifteen (15) feet; and minimum curb radius at an intersection involving a collector street or local streets in a commercial or industrial area shall be at least twenty-five (25) feet. Alley intersections and abrupt changes in alignment within a block shall have the corners cut off in accordance with standard engineering practice to permit safe vehicular movement.
