(A) The arrangement, character, width and location of all streets shall conform to the existing comprehensive/master plan or street layout plan and shall be considered in their relation to existing and planned streets, topographic conditions, public convenience and safety, and to their appropriate relationship to the proposed use of the land to be served by such streets.
(B) Where streets are not shown on a master plan, the arrangement in the subdivision shall either:
(1) Provide for the continuation or appropriate projection of existing principal streets and surrounding areas; or
(2) Conform to a plan for the neighborhood approved or adopted by the Council to meet a particular situation where topographic or other conditions make continuance of or conformance to existing streets impractical.
(C) Minor streets shall be so arranged that their use by through traffic will be discouraged.
(D) Where a subdivision abuts or contains an existing or proposed arterial street, the Council may require marginal access streets, reverse frontage with screen planting contained in a non-access reservation along the rear property line, or such other treatment as may be necessary for adequate protection of residential property and to afford separation of through and local traffic. The subdivider shall only be required to pay for his or her appropriate share of the cost of an arterial street as determined by the assessment policies of the city.
(E) Where a subdivision borders on or contains a railroad right-of-way or limited access highway right-of-way, the Council may require a street approximately parallel to and on each side of such right- of-way at a distance suitable for the appropriate use of intervening land, as for park purposes and residential districts. Such distances shall also be determined with due regard for the requirements of approach grades and future grade separations.
(F) Reserve strips controlling access to streets shall be prohibited, except where the control is placed under city jurisdiction under conditions approved by the Council.
(G) Jogs in streets with centerline offsets of less than 150 feet shall be avoided.
(H) A tangent of at least 100 feet shall be introduced between reverse horizontal curves on arterial and collector streets.
(I) Streets shall be laid out so as to intersect as nearly as possible at right angles, and no streets shall intersect any other street at less than 60 degrees. Intersections of more than four corners are prohibited.
(J) The Council may require that sight easements be provided at street intersections to ensure a sight distance of not less than 150 feet for minor and collector streets and a greater radii as the Engineer shall determine for heavier traveled streets. The Council may permit property lines at street intersections to be rounded with a radius sufficient to ensure the above stated distance in lieu of the sight easement.
(K) All cul-de-sacs and minor streets built by the developer shall be designed for a minimum seven- ton axle load or such load as set forth in the current Minnesota Department of Transportation’s (MnDOT) Road Design Manual (§ 291.5 at the date of this chapter). Thoroughfare streets, which are expected to carry heavier traffic, shall be designed for a nine-ton load, or current MnDOT manual specifications. Minimum requirements of the city are shown in division (M) of this section. This drawing shall be considered a part of these standards. Cul-de-sacs shall not exceed 600 feet in length as measured along the centerline from the intersection of origin to the end of the right-of-way.
(L) When submitting street plans to the city for approval, the developer shall submit typical design sections showing the depth and type of the base to be constructed, the thickness and type of wearing surface to be used, the width of pavement planned and the general dimensions of the roadway showing crown and related information as determined by the City Engineer to ensure adequate review of said street plans.
(M) Minimum pavement width for streets built by the developer shall be as shown in the following table.
Classification | Right-of-Way Width (ft.) | Paved Roadway Width (ft.) | Ton Loading (tons) |
Arterial | 100 | 44 | 9 |
Collector/major | 80 | 36 | 9 |
Cul-de-sac | 50 | 30 | 7 |
Minor | 60 | 30 | 7 |
(N) The street plan proposed by the developer shall meet all of the requirements of the city’s comprehensive plan for thoroughfares. Requirements to be met include those for alignment, right-of-way width, layout of intersections and related requirements. In submitting his or her proposed street plan, the developer shall provide drawings and engineering details showing the horizontal alignment and vertical grades planned for each individual street. Plans and profile elevations datum for the street grades shall be given in reference to the U.S. Geodetic Survey 1929 or the 5th General Adjustment.
(O) All underground utilities, street grading and compacted road base shall be in place before building permits will be issued to the abutting property.
(P) Street rights-of-way shall not be planned so as to cause hardship to owners of adjoining property.
