Minimum right-of-way widths. <br /> Principal arterial,intermediate arterial As recommended by the State Department of Transportation <br /> Minor arterial 80 feet <br /> Collector 70 feet <br /> Local 50 feet <br /> Parkway 100 feet <br /> Culs-de-sac 50 feet radius <br /> 1896 <br /> 1897 b. Rights-of-way are needed for future roadways in the opinion of the city. <br /> 1898 c. Right-of-way widths or additional widths in existing rights-of-way in excess of the standards <br /> 1899 designated in this chapter when,due to topography,additional width is necessary to provide <br /> 1900 adequate earth slopes.Such slopes shall not be in excess of 3:1. <br /> 1901 (b) Railroads and limited-access roadways. Railroad rights-of-way and limited-access roadways where <br /> 1902 so located as to affect the subdivision of adjoining lands shall be treated as follows: <br /> 903 (1) In residential districts,a buffer strip at least 25 feet in depth • .:: • <br /> 904 - . •.. _. • • • shall be provided adjacent to the railroad right-of-way or limited- <br /> 1905 access roadway. <br /> 1906 (2) In districts zoned for business,commercial or industrial uses,the nearest street extending parallel <br /> 1907 or approximately parallel to the railroad shall be at a sufficient distance to ensure suitable depth <br /> 1908 for commercial or industrial sites. <br /> 1909 (3) Streets parallel to the railroad when intersecting a street which crosses the railroad at grade shall <br /> 1910 be at a distance of at least 150 feet from the railroad right-of-way. Such distance shall be <br /> 1911 determined with due consideration of the minimum distance required for future separation of <br /> 1912 grades by means of appropriate approach gradients. <br /> 1913 (4) Streets Roadways crossing the railroads shall be avoided. <br /> 1914 (c) Intersections. <br /> 1915 (1) StreetsRoadways shall be laid out so as to intersect as nearly as possible at right angles. A <br /> 1916 proposed intersection of two new streets at an angle or less than 75 degrees shall not be acceptable. <br /> 1917 An oblique street should be curved approaching an intersection and should be approximately at <br /> 1918 right angles for at least 100 feet from the intersection.Not more than two streets shall intersect at <br /> 1919 any one point unless specifically approved by the city. <br /> 1920 (2) Proposed new intersections along one side of an existing street shall coincide with any existing <br /> 1921 intersections on the opposite side of such street.Intersection jogs with centerline offsets of less <br /> 1922 than 150 feet shall not be permitted,except where the intersected street has separated dual drives <br /> 1923 without median breaks at either intersection.Where streets intersect collectors or arterials,-maje* <br /> 924 streets,their alignment shall be continuous.Intersections of arterial roadways shall be at least 800 <br /> 1925 feet apart. <br /> 1926 (3) Minimum curb radius at the intersection of two local streets shall be at least 15 feet, and <br /> 1927 minimum curb radius at an intersection involving a collector street or local streets in a commercial <br /> 1928 or industrial area shall be at least 25 feet.
