When such a permit or permit application is required it shall be prepared, ready for signatures, containing all required supporting documentation, by the Design Engineer with sufficient copies for the Town to retain one.

1.10 PUBLIC IMPROVEMENT ENGINEERING PLANS & SPECIFICATIONS SUBMISSION AND REVIEW PROCEDURE

These documents requiring Town approval shall be submitted by the Design Engineer to the Town Engineer, with a letter of transmittal tabulating the items being submitted. The documents to be approved and the number required by the Town are set out below. The Design Engineer shall add to the documents the quantity he would like returned to him marked approved on their face, or in the case of permit applications, executed by the Town for submittal to other agencies.

The submittal shall be made in two parts. The initial submittal should be made and returned to the Design Engineer prior to the final submittal.

Documents included in the initial submittal are as follows:
Plans 2 sets
Specifications 2 sets

Said fee shall be applied as credit against the actual costs incurred by the Public Works Department for review of said plans and the inspection and testing of said improvements.

The balance of the actual costs shall be paid to the Town by the Developer at the time such review and inspection has been completed by the Public Works Department and prior to the town accepting the improvements for maintenance.

1.14 REVISIONS TO APPROVED PUBLIC IMPROVEMENT ENGINEERING PLANS & SPECIFICATIONS

Any deviations from approved plans or specifications affecting capacity, the Town Engineer shall approve stability or operation of the improvements in writing before such changes are made.

1.19 ELECTRONIC DRAFTING FILE STANDARDS

  1. Purpose. The purpose of these specifications is to provide a standard for the transfer media and the format of the data files for submission to the Clerk of the Town of Normal. The goal is to save the Town, consultants and developers time and money by providing a set of CAD (Computer Aided Drafting) standards that will allow for easier referencing and combining of files from one or more designs or sets of field data. By following these standards, files will be uniform allowing for quicker access and editing of files produced at any time or by different people. It will also allow the Town to automate the process of adding data to a GIS (Geographic Information System).
  2. Electronic Files Required. The electronic files submitted will be used for two purposes:
    1. GIS update – this requires the plat or project to be a homogenous continuous design based in State Plane Coordinates as outlined below in Section D. Notes are not needed.
    2. Electronic Files – this is the source for each printed page in a plat or plan. Electronic files shall be provided when submitting final copies of:
      1. Preliminary Plans
      2. Final Plats
      3. Record drawings of Public Improvement Engineering Plans (including title page, grading plan, drainage way, street, sidewalk and trail (except cross sections), storm sewer, sanitary sewer, water main, street lights, sump pump, structures).
      4. Electronic files are requested but not required for record drawings and final plats for subdivisions approved under the expedited procedure.
  3. Media. Files may be submitted on 3-1/2 inch diskette, Iomega 100 MB Zip Disks or CD-Rom. Files on floppy may be zipped as long as they are self-extracting or the extraction utility is provided. All files and media are to be an IBM compatible format.
  4. CAD Standard. This CAD (Computer Aided Drafting) standard is based on the IDOT (Illinois Department of Transportation) drafting standards where feasible. Files submitted shall be Micro station DGN files or Auto Cad DWG Version 14 or later. The files shall have the following properties:
    1. The actual working plat or design project shall use Illinois State Plane East Zone Metric coordinates, USGS Zone 3776, FIPS Zone 1201, Projection will be Transverse Mercator. The USGS Datum will be, horizontal NAD 83 and vertical NGVD 29. The plat or project shall properly edge match to adjoining plats or design.
    2. Files shall be 3D design files for plans and 2D design for plats. Individual pages such as title page or typical sections may be 2D design files.
    3. If CAD files are converted from English units to Metric units use 0.3048 ft/m for conversion.”
    4. If using AutoCAD DWG files the following applies:
      1. All unused blocks shall be purged from AutoCAD files.
    5. If using Micro Station DGN files the following apply:
      1. The Global Origin shall be set to the lower left of the design file.
      2. Working units shall be metric: 1000 sub units (mm) per master unit (m). One sub unit per positional unit. Master units shall be designated m for meters. Sub units shall be designated mm for millimeters. (Note: Dimensions placed in the design file may be in English units as required for plats or design projects, but the working units shall be metric.)
      3. Reference files used shall be in the same sub directory as the active design file. The attachment of the reference files done shall be set with “Save Full Path” off.
      4. Design files shall be compressed, to remove deleted elements, before submittal.
      5. Element attributes/symbology shall be in accordance with the following table.
