(1) Cover sheet containing the location of the development; symbols that are used; index to sheets; summary of quantities; scales that are used; appropriate place for approval of the engineer; and the signature and seal of a registered professional engineer.
(2) North arrow and bench marks with their elevations noted. Bench marks shall be referenced to mean sea level datum as determined by the United States Geological Survey, current datum.
(3) Plan sheets showing the locations of all existing and proposed streets, right-of-way lines, sanitary sewers, storm sewers, sidewalks, drainage ditches, easements, rear lot drainage, direction of storm drainage flow, survey monuments, water mains, fire hydrants, and any other appurtenance or structure that might influence design considerations.
(4) Profile sheets indicating the existing ground line and proposed grades and elevations for all proposed streets, sanitary sewers, storm sewers, drainage structures, drainage ditches and rear lot drainage. Elevations shall be referenced to the current United States Geological Survey datum.
(5) Typical sections showing right-of-way lines, proposed pavement widths, pavement thickness, base thickness, sub-base thickness, subgrade, crown, curbs and gutters, sidewalks, and design data when required.
(6) Detailed sheets showing the details of manholes, inlets, catch basins, curb and gutters, drainage structures, and any other structure or appurtenance to be constructed, or reference made to the latest edition of the Standard Specifications for Road and Bridge Construction or the latest edition of Standard Specifications for Water and Sewer Main Construction in Illinois or the latest edition of the Highway Standards published by the State Department of Transportation.
(7) Design computations for storm sewer design, special structures, and pavement designs when required, certified by a professional engineer.
(B) Basic review of the construction plans shall be completed by the village's consulting engineer within 30 days of the submission date. When construction plans have been resubmitted, they will be re-reviewed and returned to the developer's engineer within 14 days, unless review time is extended by the village's consulting engineer in a letter listing reasons for the extension. This letter will be sent to the engineer who submitted the construction plans. When the construction plans have been approved by the village's consulting engineer and the village's consulting engineer has determined that the other village departments have approved the construction plans, the developer may install the required public improvements.
(C) The village's consulting engineer shall notify the developer when the construction plans are approved and shall send a copy of such approval to the Planning Commission. Once the construction plans have been approved, the developer may proceed with the next step.
