A. Survey And Design Information Required: The preliminary plat shall be clearly and legibly drawn at a scale no greater than one inch equals one hundred feet (1" = 100') and shall contain the following information:
1. Identification And Description:
a. The proposed name of the subdivision, which shall not duplicate or be similar in pronunciation to the name of a plat previously recorded in Crow Wing County.
b. The location of the subdivision by section, township and range.
c. The name and address of the owner(s), subdivider(s), surveyor, and designer.
d. Graphic scale, north point, and date of preparation.
2. Existing Conditions:
a. A boundary line survey of the proposed subdivision, including measured distances and angles, which shall be tied into the nearest section or quarter section corner by traverse.
b. Existing zoning classifications, including shore land designations for land within the subdivision and on abutting property within three hundred fifty feet (350') of the property within the proposed preliminary plat.
c. Wetlands from the national wetlands inventory and professionally delineated wetlands on the subject property.
d. Total acreage of the preliminary plat and acreages of any wetlands therein.
e. Location, width, and name of every existing or previously platted street or private easement (either of record or any possible prescriptive easements), showing type, width and condition of improvements, railroad and utility rights of way, parks and other public open spaces, permanent buildings and structures, section lines and corporate boundaries within the proposed subdivision and within a distance of three hundred fifty feet (350') of said proposed subdivision. If the proposed subdivision gains access to a public street via a private easement, the entire easement until it intersects with a public right of way shall be depicted on the preliminary plat even if this extends beyond three hundred fifty feet (350').
f. If the proposed subdivision is a rearrangement or replat of any former plat or portion thereof, the lot and block arrangement of the original plat, along with its original name, shall be indicated by dotted or dashed lines. Also, any revised or vacated roadways of the original plat shall be so indicated.
g. Location and size of existing sewers, water mains, storm sewer mains, or other underground facilities within the proposed subdivision and to a distance of one hundred feet (100') beyond shall also be indicated.
h. Boundary lines of unplatted lands within three hundred fifty feet (350'), identified by record owner's name, shall be indicated.
i. Existing drainage patterns both within the plat and current drainage patterns showing run on and runoff from the platted land.
j. The contour line denoting land classified as flood zone A or land below the known 100-year stormwater elevation.
3. Subdivision Design Features:
a. Layout of the proposed streets showing right of way widths and proposed street names. If the proposed street is an extension of an existing named street, the name shall be used. In all other cases, the name of the street shall be consistent with the county and city street naming system as determined by E911 requirements.
b. Locations and widths of pedestrianways and utility easements.
c. Layout numbers and preliminary dimensions of lots and blocks.
d. Areas intended to be dedicated or reserved for public use, including their size in acres.
e. Areas intended for uses other than residential or public.
f. Minimum front and side building setback lines as required by the zoning ordinance.
g. An inset showing utility easements for five foot (5') side lot and ten foot (10') front.
B. Other Required Information: The following information shall be filed with or included on the proposed preliminary plat:
1. A complete topographic map, at a scale no greater than one inch equals one hundred feet (1" = 100'), with contour intervals not greater than two feet (2'), showing watercourses, wetlands, rock outcrops, and other significant features. Due to known high groundwater elevations, contour intervals of not greater than one foot (1') shall be required for applications within Section 6, Township 133N-Range 28W; Section 1, Township 133N-Range 29W and Section 31, Township 134N-Range 28W. At least one print of the preliminary plat shall be superimposed on a copy of the topographic map. USGS datum shall be used for all topographic mapping.
2. Soil absorption (percolation) tests where disposal fields are proposed for more than one dwelling unit and any other subsoil information requested by the city engineer.
3. Plans for water supply, sewage disposal, stormwater drainage system, including proposed location, size, and gradient of proposed sewer lines and water mains, and such other supporting data as may be required by the city engineer or the planning and zoning administrator.
4. Centerline gradients of proposed streets.
5. Typical cross section of proposed street improvements.
6. Where the subdivider owns property adjacent to that which is being proposed for subdivision, the city may require that the subdivider submit a sketch plat of the adjacent property so as to show the relationship of the proposed subdivision to the future development of the adjacent property.
7. Current professional delineation of all wetlands within the plat.
8. If any part of said plat is within a shore land district, such part of the plat shall show the elevation line of the shore land district boundary, ordinary high water mark and any bluffs.
9. If applicable, show the contour line of any land within a floodplain or, if the elevations for said land are not known, note accordingly.
10. Provide a construction and permanent erosion plan that details wind and water erosion control structures as well as temporary and permanent seeding.
11. Provide information on the plat to indicate that the front setback line of every lot in the plat shall be within four feet (4') in elevation from the approximate finished centerline elevation of the nearest street. If such elevations are not feasible, the planning and zoning administrator must specifically authorize any exception thereto.
12. Provide a stormwater retention plan. This plan shall be engineered so that the plat shall retain the stormwater runoff of a 100-year rain event if said plat is not served by storm sewer or some other city maintained stormwater drainage system. If the plat is served by some city maintained stormwater drainage system it shall retain the stormwater runoff of a 5-year rain event.
13. Any additional information required by the planning and zoning administrator, the planning and zoning commission, or city staff members called upon to render opinions on any part of the proposed preliminary plat.
C. Qualifications Governing Approval Of A Preliminary Plat:
1. The approval of a preliminary plat by the council shall only constitute acceptance of the design as a basis for the preparation of the final plat by the owners or subdividers. Subsequent approval by appropriate officials having jurisdiction will be required of the engineering proposals, water systems, stormwater drainage, sewage disposal, sidewalks, pathways, trails, grading, gradients and roadway widths, and the surfacing of streets prior to the approval of the final plat by the city. The subdivider shall also present evidence that the proposed plat has been submitted to the utility companies responsible for the provision of natural gas, electric power, and telephone services.
2. No preliminary plat will be approved for a subdivision which includes an area which contains poor drainage facilities which would render inadequate the streets or building sites proposed by reason of such plat, unless the subdivider agrees to make improvements which will, in the opinion of the city engineer, make such areas completely usable and safe for occupancy and provide for adequate street and lot drainage.
3. If wetland fill permits are required for development of roadway, trail, building site or other reasons, the city council may require the fill permits to be acquired prior to final plat approval. (Ord. 2014-02, 2-18-2014)
