A. Streets, Continuous: Except for cul-de-sacs, streets shall connect with streets already dedicated in adjoining or adjacent subdivisions, or provide for future connections to adjoining unsubdivided tracts, or shall be a reasonable projection of streets in the nearest subdivided tracts. The arrangement of arterial and collector streets shall be considered in their relation to the reasonable circulation of traffic, to topographic conditions, to runoff of stormwater, to public convenience and safety, and in their appropriate relation to the proposed uses of the area to be served.
B. Local Streets: Local streets should be so planned as to discourage their use by nonlocal traffic.
C. Street Plans For Future Subdivisions: Where the plat to be submitted includes only part of the tract owned or intended for development by the subdivider, a sketch plan of a proposed future street system and lot layout for the unsubdivided portion shall be prepared and submitted by the subdivider.
D. Temporary Cul-De-Sacs:
1. In those instances where a street is terminated pending future extension in conjunction with future subdivision and there is more than two hundred feet (200') or two (2) dwelling units accessed between the dead end and the nearest intersection, a temporary turnaround shall be provided at the closed end in conformance with cul-de-sac requirements.
2. The temporary cul-de-sac must be placed inside a temporary roadway easement if it is located outside street right of way.
3. The temporary cul-de-sac shall be paved with bituminous within one year of construction.
4. The developer shall submit a cash escrow in an amount as determined by the city engineer for removal of the temporary cul-de-sac and restoration of the area limited to placement of sod and asphalt driveway within the temporary roadway easement.
E. Provisions For Resubdivision Of Large Lots And Parcels: When a tract is subdivided into larger than normal building lots or parcels, such lots or parcels shall be so arranged as to permit the logical location and openings of future streets and appropriate resubdivision, with provision for adequate utility connections for such resubdivision.
F. Street Intersections: Under normal conditions, streets shall be laid out so as to intersect as nearly as possible at right angles, except where topography or other conditions justify variations. Under normal conditions, the minimum angle of intersection of streets shall be eighty degrees (80o). Street intersection jobs with an offset of less than one hundred twenty five feet (125') shall be avoided.
G. Subdivisions Abutting Major Rights Of Way: Wherever the proposed subdivision contains or is adjacent to the right of way of a U.S. or state highway or arterial, provision may be made for a marginal access street approximately parallel and adjacent to the boundary of such right of way; provided, that due consideration is given to proper circulation design, or for a street at a distance suitable for the appropriate use of land between such street and right of way. Such distance shall be determined with due consideration of the minimum distance required for approach connections to future grade separations, or for lot depths.
H. Sidewalks And Multipurpose Trailways:
1. Concrete sidewalks shall be installed along one side of all local streets (not including cul-de-sacs) within residential district plats and along both sides of local streets within commercial and mixed use district plats and along both sides of minor collector streets designated by the city's transportation plan. All sidewalks shall have a minimum width of five feet (5') except sidewalks in commercial and mixed use plats, which shall have a minimum width of eight feet (8').
2. Multipurpose trailways shall be installed on both sides of major collectors, arterials and other designated roadways as shown in the parks, trails and open space plan. Unless otherwise directed by the city council, all multipurpose trailways identified by the parks, trails and open space plan shall have a minimum width of ten feet (10') and be constructed of bituminous materials.
3. Concrete sidewalks and multipurpose bituminous trailways shall be accessible by handicapped persons in accordance with Minnesota statutes section 471.464.
4. The subdivider shall be responsible for the payment of the cost of sidewalks. The cost of multipurpose trailways shall be apportioned: subdivider one hundred percent (100%) of the cost of grading and restoration and five- eighths (5/8) of all other costs, city three-eighths (3/8) of cost excluding grading and restoration.
I. Service Access, Alleys: Service access shall be provided in commercial and industrial districts for off street loading, unloading and parking consistent with and adequate for the uses proposed. Except where justified by special conditions, such as the continuation of an existing alley in the same block, alleys will not be approved in residential districts. Alleys, where provided, shall not be less than thirty feet (30') wide. Dead end alleys shall be avoided wherever possible, but if unavoidable, such dead end alleys may be approved if adequate turnaround facilities are provided at the closed end.
J. Half Streets: Dedication of half streets shall not be considered for approval except where it is essential to the reasonable development of the subdivision and in conformity with the other requirements of these regulations or where it is found that it will be practical to require the dedication of the other half when the adjoining property is subdivided.
K. Compliance With The Dakota County Transportation Plan: All subdivisions incorporating streets which are identified in the county transportation plan, as amended, shall comply with the minimum right of way, surfaced width, and design standards as outlined in said plan, and must be reviewed and approved by the Dakota County plat commission.
L. Street Grades: Except when, upon the recommendation of the city engineer, the topography warrants a greater maximum, the grades in all streets, arterials, collector streets, local streets and alleys in any subdivision shall not be greater than ten percent (10%). In addition, there shall be a minimum grade on all streets and arterials of not less than five-tenths percent (0.5%) unless approved by the city engineer because of existing conditions.
M. Curb Radius: The minimum curb radii for arterials, collector streets, local streets and alleys shall be as follows:
Alleys and driveways | 5 feet |
Arterial and collector streets | 25 feet |
Local streets | 15 feet |
N. Reverse Curves: Minimum design standards for collector and arterial streets shall comply with Minnesota state aid design standards.
O. Reserve Strips: Reserve strips controlling access to streets shall be prohibited except under conditions accepted by the city council.
P. Street Right Of Way Widths: Unless approved by the city engineer to match existing adjacent right of way, street right of way widths shall conform to the following standards:
Function Classification | Right Of Way Without Trails/Sidewalks | Right Of Way With Trails/Sidewalks |
Function Classification | Right Of Way Without Trails/Sidewalks | Right Of Way With Trails/Sidewalks |
A-Minor expander | n/a | 150 feet |
