Where the preliminary layout covers only a part of the subdivider's entire holding, a sketch of the prospective lot layout and street system of the unsubmitted part shall be furnished and the street system of the submitted part will be considered in the light of adjustments and connections with the street system of the part not submitted.
The preliminary plat shall be drawn on tracing paper or tracing cloth having a minimum size of twenty four inches by eighteen inches (24" x 18"), in a manner that clear and legible prints can be made and shall show the following:
A. Identification And Description:
1. Proposed name of subdivision not duplicating name of any plat heretofore recorded in the Village or in Grundy County and/or Will County, Illinois.
2. Location by section, town and range, or by other approved legal description.
3. An accompanying boundary line survey map with accurate distances and angles prepared and certified by a registered surveyor and an accompanying topographic map indicating source of survey shall accompany the preliminary plat.
4. Names and addresses of the owner or subdivider of the proposed subdivision and designer of such subdivision and date of preparation.
5. Graphic (engineering) scale, which shall not exceed one hundred feet to one inch (1" = 100').
6. North point (designated as true north).
B. Existing Conditions:
1. Boundary lines of proposed subdivision in accordance with subsection A3 above.
2. Total acreage therein.
3. Existing zoning districts in proposed subdivision and adjacent tracts.
4. Location, widths and names of all existing or previously platted streets or other rights of way showing type of improvement (if any), railroad and utility rights of way, parks and other public open spaces, permanent buildings and structures, easements and section and corporate lines within the tract and to a distance of one hundred feet (100') beyond the tract.
5. Location and size of existing sewer lines, water mains, culverts or other underground facilities within the tract and to a distance of one hundred feet (100') beyond the tract; also locations of catch basins, manholes, valves and hydrants, and indicating such data as surface and invert elevations. (Ord., 5-15-1974)
6. Location map shall be required by the Planning and Zoning Commission, drawn at a scale of not less than one inch equals one thousand feet (1" = 1,000'), showing boundary lines of adjoining unsubdivided or subdivided land within an area bounded by nearest thoroughfare or other natural boundaries, identifying type of use of surrounding land and showing alignments of existing streets.
7. The Planning and Zoning Commission shall require topographic data including existing contours at vertical intervals of not more than two feet (2'), except in unusual topographical conditions, such vertical intervals may be required to be altered as determined by the Village Engineer, (topographic data shall refer to United States Geodetic Survey or adjusted County datum); and locations of watercourses, marshes and other significant features. Soil boring data and seepage tests may be required at locations and depths as determined by the Village Engineer. (Ord., 5-15-1974; amd. Ord. 1993-12, 8-24-1993)
8. Locations of or references to locations of existing monuments or survey markers used in preparation of survey and grade elevation of each monument and marker.
C. Subdivision Design Features:
1. The preliminary plan shall be in substantial accord with the comprehensive plan as amended from time to time.
2. Layout of streets showing right-of-way widths and street names (not duplicating the name of any street heretofore used in the Village and its environs unless such street is an extension of or in line with an already named street, in which event that name shall be used) and showing proposed through streets extended to boundaries of subdivision.
3. Location and width of alleys, pedestrianways and utility easements.
4. Layout, total number of lots and dimensions of the lot containing the minimum width and depth and the lot containing the maximum width and depth.
5. Minimum front and side street building setback lines, indicating dimensions.
6. Areas (other than those listed in subsection C2, 3 and 4 above), if any, intended to be dedicated or reserved for nonresidential purposes, indicating in each the approximate acreage. Such areas shall be designated by letter or number.
7. Typical cross-section of streets and alleys, together with an indication of the proposed storm water runoff. (Ord., 5-15-1974)
8. When recommended by the Village Engineer and required by the Planning and Zoning Commission, the subdivider shall submit proposed detailed grading plans of blocks and lots. No land will be approved for subdivision which is subject to periodic flooding, or is within a flood plain, or which contains inadequate drainage facilities or other topographic conditions which may increase danger to health, life or property or aggravate erosion or flood hazard unless the subdivider agrees to make improvements which will, in the opinion of the Village Engineer and Planning and Zoning Commission, make such land safe for development and occupancy. (Ord., 5-15-1974; amd. Ord. 1993-12, 8-24-1993)
9. Land lying wholly or partially within a flood plain may be laid out and slotted or divided as building lots; provided, that part of site to be used for building location shall have an elevation of not less than one foot six inches (1'6") above flood crest, and that said lots be filled in from the building site to the curb in a gradual slope, and that the yard surrounding the building site on the other three (3) sides be filled in to a reasonable slope, to meet the existing elevation to be determined by the Building Officer.
