Sec. 10-247 Preliminary Plat.
   The following maps and data shall be submitted with the application for Preliminary Plat Approval. The maps and data may be on separate sheets or combined on one (1) sheet, depending on the size and complexity of the proposed subdivision.
   A.   A location map of the proposed subdivision showing:
      1.   Location within the Town and a metes and bounds description tied to a U.S. Land Survey Section Corner.
      2.   Zoning of the tract and adjacent properties, as well as indication of any covenants on the property.
      3.   Gross land area and density (# lots/acre).
      4.   Contours of the site at vertical intervals of two feet (2'), with reference to USGS data.
      5.   Character and location of natural or artificial features existing on the land which would affect the design of the subdivision, such as wooded areas, streams, direction and gradient of ground slope, embankments, retaining walls, buildings, or nonresidential usage of land; and wetland areas.
      6.   Existing and proposed street patterns, rights-of-way, including approximate gradients; types and widths of pavements, curbs and sidewalks; distances and the like.
      7.   Existing and proposed easements, including widths and purposes.
      8.   Existing utilities, including the size, capacity, and location of sanitary sewers, storm sewers, drainage facilities, water lines, gas mains, and power lines on adjacent properties.
      9.   Areas subject to periodic overflow of flood or storm waters (Flood Plain information).
      10.   Subsurface conditions, including information about ground water levels and stability of subsoils; soil type -(Soil Map of Lake County).
      11.   Tract boundary lines by calculated distances and bearings, with reference to a Section Comer.
      12.   Title, graphic scale, north point and date.
      13.   Site map of all lands within one hundred feet (100') boundaries.
   B.   A Subdivision Plat of the proposed subdivision drawn at a scale no smaller than one hundred feet (100') to one inch (1") showing:
      1.   Subdivision Name
      2.   Names and addresses of owner, subdivider, and the person who prepared the plat.
      3.   Street pattern, including the names (which shall not duplicate existing streets in the Town unless it is an extension of an existing street), widths of rights-of-way of streets, widths of easements for alleys, approximate grades of streets where they exceed eight percent (8%).
      4.   Layout of lots, including dimensions and total square footage, lot and address numbers, building set-back lines, front yard lines, and width of lot at building set-back line.
      5.   Parcels of land to be dedicated or reserved for schools, parks, playgrounds or other public or community use.
      6.   Key plan, legend, notes, graphic scale, north point and date.
      7.   Legal description of property to be subdivided with exact length and bearings of the first degree of accuracy of the exterior boundaries.
   C.   Engineering Plans for the proposed subdivision showing:
      1.   Plan and profile of the proposed street, sanitary and storm sewers, and water distribution system.
      2.   General explanatory data concerning the installation of water distribution systems, storm sewers, and sanitary sewers, as said improvements relate to the total utility system.
      3.   Approval of connection to an existing sewer system, service load of the subdivision and capacity of the treatment plant, by the appropriate Town Staff. In the event that a lift station is required, as per Town Staff, it shall be designed to accommodate the present and future development of the total area that may be serviced. The subdivider shall be responsible for the cost of maintaining said lift station for a period of two (2) years.
      4.   If connection to a public sewerage system is not feasible, a report on the feasibility of on-lot sewerage disposal, including a detailed map of the physical conditions of the site, contours, finished grades, water courses, ground water table elevations, and the results of soil percolation tests for each individual lot conducted in accordance with the recommended practices of the Indiana State Board of Health.
      5.   Proposed storm retention/detention design and calculations. Detention areas, when possible, should be part of a subdivision lot and should be maintained by the lot owner, and shall discharge into an adequate drainage system. Detention areas shall be at a slope of five (5) to one (1) or as approved by the Town Engineer. Detention areas reserved for public use shall be covered with four (4) inches of black dirt, graded and seeded before dedication and acceptance by the Town.
      6.   Relationship of the subdivision's storm drainage system to the total water shed.
      7.   Bench marks located within a fifteen hundred (1500) feet radius of each lot, referenced by USGS Datum.
      8.   Each lot shall bear an elevation notation which is not lower than 16 inches (16") above the top of the curb(s) at the average point of the curb(s) adjoining the lot, related to the United States Coast and Geodetic Survey Datum, of the minimum elevation of the entrance into any principal use structure built on that lot. Said elevation shall be planned to avoid direct flow of storm water runoff into the principal use structure, provided however, that under unusual topographical conditions the lowest elevation entrance requirements may be waived by the Plan Commission on the original plat, or by the Town Engineer in writing on a form approved by the Plan Commission. Elevations of the proposed building's entry level, the ground elevations at the corners of the building, and elevations of the lots corners as well as the overland flow shall also be shown on the plan.
   D.   Restrictions: a draft of the protective covenants or private restrictions to be adopted in the final subdivision plat.
