(A) The subdivider shall provide a plan for the subdivision which shall show the manner in which the proposed subdivision is coordinated with the Master Plan and its provisions, specifically with relation to the requirements of the Official Major Streets and Highways Plan, and those items reviewed during the preliminary consideration; provided, however, that no land shall be subdivided for residential use unless adequate access to the land over improved streets or thoroughfares exists or will be provided by the subdivider, or if such land is considered by the Commission to be unsuitable for such use by reason of flooding or improper drainage, objectionable earth and rock formation, topography, or any other feature harmful to the health and safety of possible residents and the community as a whole.
(B) The subdivider shall provide the following:
(1) Location map. A location map, which may be prepared by indicating the data by notations on available maps, showing:
(a) Subdivision name and location.
(b) Any thoroughfares related to the subdivision.
(c) Existing elementary and high schools, parks and playgrounds, shopping centers or stores serving the area proposed to be subdivided, and other community facilities.
(d) Zoning of the site and adjoining property
(e) Nearest approved drainage outlet.
(f) Title, scale, north point and date.
(2) Preliminary plat. A preliminary plat showing:
(a) Proposed name of subdivision.
(b) Names and addresses of the owner, subdivider and the planner, land planning consultant, professional engineer or registered surveyor who prepared the plan.
(c) Streets and rights-of-way on and adjoining the site of the proposed subdivision showing the names (which shall not duplicate other names of streets in the community, except as designated by the Commission) and including roadway widths, approximate gradients, types and widths of pavement, curbs, sidewalks, cross-walks and tree planting.
(d) Easement locations, widths and purposes.
(e) Existing sewers, water lines, culverts and other underground structures, and power transmission poles and lines, within and adjacent to the tract.
(f) Layout of lots showing dimensions and numbers.
(g) Parcels of land proposed to be dedicated or reserved for schools, parks, playgrounds or other public, semi-public, or community purposes.
(h) Contours at vertical intervals of two feet if the general slope of the site is less than 10% and at vertical intervals of five feet if the general slope is greater than 10%.
(i) Tract boundary lines showing dimensions, bearings, angles and references to section, township and range lines or corners.
(j) Building lines.
(k) Legend and notes.
(l) Other features or conditions which would affect the subdivision favorably or adversely.
(m) Scale, north point and date. The preliminary plat of the subdivision shall be drawn to a scale of 50 feet to 1 inch or 100 feet to 1 inch; provided, however, that if the resulting drawing would be over 36 inches in shortest dimension, a scale as recommended by the Commission may be used.
(n) Plans and specifications for the improvements required in this chapter.
(o) Detailed grading plans shall be submitted simultaneously with the preliminary plat to illustrate solutions to topography or drainage problems
1. These plans shall show topographically and by profile the elevation of the land prior to any phase of subdividing, and any proposed changes in elevations and flow of surface water resulting from proposed subdivision development. Such plans shall be of the same scale and size as the preliminary plat and shall be prepared in such a manner as will permit the topographic detail to be used as an overlay to the preliminary plat.
2. Upon the face of the subdivision plat, certification is required by a Registered Professional Engineer or Land Surveyor, and the owner of the land or his or her duly authorized attorney confirming that to the best of their knowledge and belief, the drainage of surface waters will not be significantly changed by the construction of such subdivision or any part thereof, or that if such surface water drainage will be changed, adequate provision has been made for such surface waters.
(3) Description of protective covenants. A description of the Protective Covenants or private restriction to be incorporated in the plat of the subdivision shall be submitted.
(4) Soil report. A soils report for the site shall be prepared by technical personnel of the Soil and Water Conservation District, or by an engineer registered in the state. This report shall indicate the degree of limitations of the soils in the proposed subdivision with respect to the proposed building development, road, construction, drainage, sewage disposal system, erosion control, and such other information that might assist the Commission in its review of the preliminary plat.
(5) Area Drainage Map. An area drainage map showing the following shall be submitted:
(a) Total drainage area.
(b) Size and location of an outlet as defined in § 152.65 to which the water from the proposed subdivision will be taken.
(c) Size and location of any regulated drain which will be affected by the proposed subdivision.
(d) Cross-sections of open ditch outlets and invert elevations of tile outlets shall be shown.
(e) Proposed location of all surface and subsurface drainage systems, as required in § 152.65.
(f) Scale and north arrow.
(6) Erosion control plan. An erosion control plan which will adequately control soil erosion and the resulting sedimentation from occurring during and after the development of a subdivision shall be submitted. This erosion control plan shall include the following:
(a) Plans and specifications of all necessary soil erosion and sedimentation control measures in accordance with standards and specifications of the Soil and Water Conservation District.
(b) A timing schedule indicating the anticipated starting and completion dates of the development sequence and the time of exposure of each area prior to the completion of effective erosion and sediment control measures.
(C) The application shall be accompanied by a certified check or money order in the amount of $50 plus $5 for each lot in the proposed subdivision to cover the cost of checking and verifying the proposed plat, and such amount shall be deposited in the General Fund of the county.
