(A) Generally. Subdivision of a parcel of land into four or more lots, counting the balance of the original parcel as one of the four, shall require platting as a major subdivision. Regardless of the number of lots involved, creation of any new street in the division of land shall also be by means of a major subdivision plat. In addition, a major subdivision plat shall be required when any parcel of land previously divided as a minor subdivision is further divided.
(B) Sketch plan. Prior to the submission of a preliminary subdivision plat, the subdivider shall submit a sketch plan and soils report from the County Soil and Water Conservation District Soil Survey Publication indicating degree of soil limitation and consult informally with the Plan Commission. This will enable the subdivider to become familiar with the general requirements and conditions affecting the subdivision, thus avoiding unnecessary and costly revisions. The sketch plan may be in a very tentative form. However, it should provide adequate information and sufficient detail for intelligent review and comment.
(C) Preliminary plat.
(1) A preliminary plat and an application shall be submitted to the Plan Commission for a major subdivision. Preliminary plat approval by the Plan Commission shall be given only after a legally advertised public hearing has been held.
(2) The preliminary plat shall be on a 24- by 36-inch sheet at a scale clearly legible and in no case shall it be less than one inch equals 100 feet. The following information shall be provided on the plat:
(a) Name of proposed subdivision;
(b) Complete legal description;
(c) Name and address of subdivider (owners and developers);
(d) Name, address and registration number of surveyor;
(e) Scale, graphic bar, north point and date;
(f) Dimensioned boundary line of proposed subdivision;
(g) Layout of all proposed and existing lots appropriately numbered and dimensioned, including setback lines;
(h) Street layout, proposed rights-of-way, easements, common areas and dedications;
(i) Location, width and names of existing streets, easements, section and corporate lines; and
(j) Existing topographic contours at vertical intervals of five feet or less. United States Geological Survey data may be used unless unusual characteristics exist which would require greater detail.
(D) Supporting data. Includes the following:
(1) All existing permanent features, natural or human-made, that may influence the design of the subdivision, such as water courses, tree groves, swamps, outstanding natural topographic features, power transmission towers, sewers, water mains, utility lines and fire hydrants. Where underground utilities exist within or adjacent to the tract, the location, size and direction of flow shall be indicated;
(2) A soils report from the County Soil and Water Conservation District indicating the degree of limitation on the soil of the proposed subdivision. The report shall indicate degree of limitation with respect to road construction, drainage, sewage disposal, erosion control and other information helpful to the review of the plat;
(3) Existing street pattern for the area adjacent to the subdivision and a plan showing the manner in which the streets within the proposed subdivision can be tied in with existing streets;
(4) A drainage plan showing the natural watercourse, marshes and the like, existing drainage facilities, culverts and the like, proposed contours and grading plan and the proposed drainage plan for the subdivision and an analysis of existing drainage facilities to nearest watercourse, showing culverts, retention ponds and the like;
(5) All land contiguous to the proposed subdivision owned by or under the control of the subdivider;
(6) An engineering feasibility report including the following:
(a) The feasibility of connecting to an existing sewerage system and water supply. This portion of the study shall include the distance to the nearest public sewer, its capacity and present load and its capacity to handle the additional sewage load created by the subdivision; and
(b) The same information shall be submitted for the water supply. A study of the storm water drainage for the area, a method of dispersion or retention and adequacy of downstream facilities. This study shall give consideration to both water entering the subdivision from adjacent land and water within the boundaries of the subdivision.
(7) Names and addresses of all property owners of record within a radius of 300 feet from all plat boundary lines.
(E) Final plat.
(1) Application for the final approval of a subdivision plat shall not be filed until the preliminary plat and supporting data has received final Plan Commission action and the preliminary plat amended in accordance with and to meet all requirements and conditions.
(2) If a subdivision is to be constructed in phases or sections, the subdivider may request final plat approval for that portion of the approved preliminary plat that is scheduled for initial construction. However, no phase or section shall contain less than 10% of the total number of lots in the approved preliminary plat.
(3) Submission of a final plat with a request for phase or section final approval shall be closely studied and considered as to the effect it may have on the continuity of roads, utilities and services. Final plat approval shall not be granted on any single phase or section of a plat that cannot stand alone should the balance of the approved preliminary plat not be constructed as originally presented.
(4) A plat approved for phase or section construction shall clearly indicate the phase or section number or letter designation as a part of the name of the subdivision title. A phase or a section of a plat shall be filed with the County Recorder and meet all requirements the same as if the entire plat were being filed at one time.
(5) The subdivider shall submit the original drawing on 24- by 36-inch vellum, linen or mylar film at a scale no less than one inch equals 100 feet.
(6) The final plat shall include:
(a) Name of subdivision;
(b) Complete legal description;
(c) Certification of land surveyor;
(d) Approval of Plan Commission;
(e) Scale, graphic bar, north point and date;
(f) Owner's certification;
(g) Boundary of plat, based on an accurate traverse, with angular and lineal dimensions;
(h) Lots dimensioned in feet and hundredths thereof, angles and/or bearings expressed in degrees, minutes and seconds and all lots appropriately numbered or similarly identified;
(i) Location, width and name of streets within the plat, utility easements and any other ground that will be dedicated for public purposes;
(j) Building setback lines accurately shown in accordance with Chapter 152 of the town code of ordinances;
(k) True angles and distances to the nearest established street lines or official monuments, which shall be accurately described in the plat. Also, the locations of the subdivision corner points and the location of the elevation benchmarks as well as accurate location of all monuments; and
(l) Radius and angle of intersection, tangent length, length of curve, P.C.s and P.T.s, radii, internal angles, points and curvatures, tangent bearings and length of all arcs.
(7) Restrictive covenants regulating the use and development of the lots may be lettered on the final plat or made a part thereof, subject to the approval of the Plan Commission; and
(8) The owner's acknowledgment of the subdividing of the real estate, the dedication of streets and other public areas and the reserving of easements for public utility purposes and drainage facilities shall be shown on the plat or separately and made a part thereof subject to the approval of the Plan Commission.
