c. Design features.
(1) Layout of proposed streets showing the right-of-way widths, centerline gradients, typical cross sections and proposed names of streets in conformance with city and county street identification policies. The name of any street heretofore used in the city or its environs shall not be used unless the proposed street is a logical extension of an already named street, in which event the same name shall be used.

(3) Locations and widths of proposed alleys and pedestrian ways.
(4) Location, dimension and purpose of all easements.
(5) Layout, numbers, lot areas and preliminary dimensions of lots and blocks. All lots shall be numbered clockwise in each block and blocks shall be numbered consecutively.
(6) Minimum front, side and rear building setback lines.
(7) When lots are located on a curve, the width of the lot at the building setback line.
(8) Areas, other than streets, alleys, pedestrian ways and utility easements, intended to be dedicated or reserved for public use, including the size of the area or areas in square feet and acres.
(9) A statement of the proposed use of lots stating type of buildings with number of proposed dwelling units or type of business, so as to reveal the effect of the development on traffic, fire hazards and congestion of population.
(10) Public utilities, including water, sanitary sewer mains and service connections to be installed in accordance with the standards of the city.
(11) Proposed grading, including existing and proposed contours at vertical intervals of not more than two feet, proposed cut and fill areas, proposed building pads showing type of house (full basement, walkout, split entry and the like) and elevations of lowest floor and garage floor.
(12) Proposed ponding data, including the ordinary high water level, high water level and emergency overflow elevation and route.
d. Supplementary information.
(1) Any or all of the supplementary information requirements set forth in this subdivision shall be submitted, when deemed necessary by the city staff, consultants, advisory bodies or City Council.
(2) Proposed protective covenants.
(3) An accurate soils report of the subdivision prepared by a registered professional engineer qualified to perform and analyze soil materials under the laws of Minnesota. The soils report shall consist of test holes to a depth necessary to determine the various types of soils to be encountered before reaching a stable base and the static water table elevation. The test holes, when ordered by the city authorities, shall be drilled at the expense of the owner or developer and the information disclosed shall be furnished to the city, together with a copy of the proposed plat showing the location of each test hole. The information required by the city shall include a report as to the various types of soils encountered and their depths, the level of the ground water, a percolation test and may include additional information. The number of test holes to be drilled and their location on the property, which is proposed to be platted, will be as directed by the city or their authorized representative. The owner shall be required to furnish to the city a report from a recognized engineering laboratory as to the safety and practicability of the use of the area for building construction.
(4) A survey prepared by a qualified landscape architect, forester or arborist identifying tree coverage in the proposed subdivision in terms of type, weakness, maturity, potential hazard, infestation, vigor, density and spacing.
(5) If any zoning changes are contemplated, the proposed zoning plan for the areas, including dimensions, shall be shown. The proposed zoning plan shall be for information only and shall not vest any rights in the applicant.
(6) Provision for surface water disposal, ponding, drainage and flood control.
(7) Where the subdivider owns property adjacent to that which is being proposed for the subdivision, it shall be required that the subdivider submit a sketch plan of the remainder of the property so as to show the possible relationships between the proposed subdivision and the future subdivision. In any event, all subdivisions shall be required to relate well with existing or potential adjacent subdivision.
(8) Where structures are to be placed on large or excessively deep lots that are subject to potential replat, the preliminary plat shall indicate a logical way in which the lots could potentially be subdivided in the future.
(9) A plan for soil erosion and sediment control both during construction and after development has been completed. The plan shall include gradients of waterways, design of velocity and erosion control measures, design of sediment control measures and landscaping of the erosion and sediment control system.
(10) A vegetation preservation and protection plan that shows those trees proposed to be removed, those to remain and the types and locations of trees and other vegetation that are to be planted.
(11) The other information as may be required.
