If the Commission approves development in phases under the terms of this chapter, the preliminary plat may be for only the first phase of the subdivision.
(A) All subdivisions of land meeting the definition of “major subdivision” in § 156.006 may be submitted to the Commission for preliminary approval as specified in this section.
(B) Required submission materials. All requests for primary approval shall be submitted with the items listed in this section.
(1) Filing fee as established by the Commission;
(2) Preliminary plat. An applicant for primary approval shall submit a set of drawings conforming to the survey and drafting standards contained in §§ 156.175 through 156.178; except that, scalar rather than computed dimensions may be shown and copies (with the number to be specified by the Department) of the drawing(s) showing the following:
(a) Legal description of the subdivision;
(b) Bar scale (the scale shall be 50 feet to the inch or larger, unless the property involved in the subdivision is of a size or shape which requires a smaller scale to fit on the required sheet size, in which case another scale approved by the Department may be used);
(c) Lot numbers, scalar layout, dimensions and sizes in square feet or acres;
(d) Accurate locations of all existing and platted streets intersecting the boundaries of the tract;
(e) Source of the owner’s title to the land as shown by the last entry in the records of the County Recorder;
(g) Accurate locations and dimensions of any property to be dedicated to the public or reserved for public, semi-public or community use;
(h) Street rights-of-way as established by the official thoroughfare plan of the county;
(i) Topographic contours at vertical intervals of five feet for areas containing land with 10% slope or greater, and at intervals of two feet for areas containing land with less than 10% slope. The topography may be shown on a separate print, but it shall be shown at the same scale as the original plat;
(j) Delineation of flood plain boundaries, indicating the classification of each flood plain area;
(k) Location, size, elevation and other appropriate description of all existing or proposed permanent features, either natural or human-made, including, but not limited to, streets, sewers, drains, water bodies, swamps or other wetlands, railroads, transmission towers, existing structures, county ditches, legal drains, water mains, culverts, utility lines, fire hydrants, drainage structures and significant topographic features. Water elevations of adjoining lakes and streams at the date of the survey and the approximate high- and low-water elevations. All elevations shall be referred to the U.S.G.S. datum plane;
(l) Location of pedestrian circulation system, if any, and the materials to be used for the system;
(m) Delineation of the phases, if any, of the development, indicating the lots and improvements to be included in each phase; and
(n) Area location map.
(3) Supporting material. An applicant for primary approval shall submit the following supporting material with the preliminary plat:
(a) One application, on forms specified by the Department;
(b) The names and addresses of all interested parties as defined by this chapter, keyed to a map;
(c) Erosion control plan (see § 156.097);
(d) Sewage disposal plan;
(e) Drainage report (see § 156.097);
(f) Copies of all restrictions and/or covenants which will run with the land;
(g) Zoning classifications of the property included in the subdivision;
(h) Specifications for any required improvements to existing county roads;
(i) Delineation on a U.S.G.S. base map of the drainage area in which the subdivision is located and of the location of drainage courses and surface water flow within the drainage area;
(j) For any improvements or systems which are to be owned and/or maintained by the property owners in the subdivision, a plan for establishing the ownership and for providing and financing the maintenance. Documents and/or plans submitted under this section are subject to determination by the Commission that they are adequate to ensure that the county will not be held responsible in the future for the maintenance;
(k) Sewage system approval:
1. If the development is to contain individual subsurface disposal systems, the applicant must show that the design criteria in §§ 156.090 through 156.099 are met, and in addition, the applicant must provide for each lot a certificate from the County Health Department indicating that a system can be installed on the property and detailing any conditions to be placed upon the installation. The Commission may require these conditions to be recorded as part of the approved subdivision.
2. If the development is to be served by a public or semi-public sewer system, the applicant must provide evidence that the system has the capacity and capability to serve the development and guarantees of a sufficient number of hook-ons to serve all lots in the subdivision.
3. If the development is to be served by a private system, the applicant must provide evidence that the system design has been approved by the State Department of Environmental Management, that there are arrangements to ensure continued operation and maintenance of the system, that the system has or will have sufficient capacity to serve the development and guarantees of a sufficient number of hook-ons to serve all lots in the subdivision.
(l) A list specifically citing any requirements of this chapter for which modifications are requested and the reasons for the request;
(m) Land suitability summary (see § 156.091), containing the following information:
1. For lots which will be served by individual subsurface disposal systems, the number of acres or square feet of contiguous land containing slopes of less than 10% and the minimum land area required by the regulations of the State Department of Health for a filter field on the lot;
2. For lots which contain water bodies, the number of acres or square feet of contiguous land area on the lot, the minimum lot size for the zone district in which the lot is located, and a calculation of 75% of the minimum lot size for the zone district in which the lot is located;
3. For lots which will be served by individual subsurface disposal systems, the number of acres or square feet of land containing soils having slight or moderate limitations for septic systems, a calculation as to the size of an individual subsurface disposal system which will be sufficient to accommodate the wastewater generated by the uses permitted on the property, and the number of acres or square feet of land containing soils indicated by the soil survey of the county to have severe limitations for septic systems; and
4. The number of acres or square feet of land which is located in a floodway, a floodway fringe, a Zone A District (with each type of flood hazard area calculated separately) and the amount of land which is not located in a flood hazard area.
(o) If any lot or road in a major subdivision is to receive access from or intersect with a state highway, a copy of the driveway permit or approval letter issued by the State Department of Transportation shall be submitted.
(D) Length of approval. Primary approval shall be valid for one year from the date of approval by the Commission. The Commission may establish time limits of less than one year on any or all conditions of primary approval. If the Commission approves development in phases, secondary approval of each phase shall automatically continue the primary approval of the remaining phases to the same expiration date as that for the secondary approval.
