The procedure for submitting the engineering plans and specifications for the subdivision is stated herein. The Village Engineer shall not recommend approval of the plans and specifications to the Village Board of Trustees until all of the information submitted is in accordance with the standards and procedures herein stated.
All engineering plans and specifications for any subdivision shall be prepared by the developer's engineer, and before the complete improvements are approved or accepted by the Village such engineer shall furnish the Village a completion certificate stating that such improvements comply with all the requirements of said engineering plans and specifications. The engineer's certificate must be accompanied by the appropriate testing data as specified in these documents. The engineering plans and specifications referred to in the preceding paragraph shall, after certification by an Illinois-registered professional engineer and after the approval of the Village Engineer, constitute part of the official plan of the Village, when applicable. The engineer who will certify the construction of the improvements shall not have an ownership interest nor be a regular employee of the subdivider. The engineer shall furnish the Village Engineer three paper sets and one electronic (.pdf) copy of approved engineering plans and specifications prior to starting any construction operations. The plan sheets shall be 11 inches by 17 inches in size. The minimum graphic scale shall be one inch equals 50 feet or other scale approved by the Village Engineer. The plans shall include the following items as required for the particular development:
A. 
Cover sheet depicting the project location and the engineer's embossed seal and original signature; also see procedures for Village certificates required;
B. 
Topographic map showing existing spot elevation, contours and proposed contours and proposed spot elevations related to National Geodetic Vertical Datum of 1988 (mean sea level) with a contour interval not greater than two feet, on the site and within 100 feet of the boundaries of the site and for the additional distances needed to adequately depict the prevailing drainage conditions and directions;
C. 
Street and storm sewer plan;
D. 
Street and storm sewer profiles;
E. 
Sanitary sewer plan;
F. 
Sanitary sewer profiles;
G. 
Water distribution plan (if water supply by Utilities, Inc. or any of its successor owner of the Oakwood Potable Water System is proposed, this data can be shown on the sanitary sewer plan);
H. 
Streetlights are to coordinate with fire hydrant and intersection locations. Plans for layout, design and installation of streetlights, wiring and all required excess facilities, which includes streetlights, poles, all devices and materials to install streetlights, shall be submitted to the Village of Oakwood and the appropriate electrical utility for approval prior to installation;
I. 
Surface swale plan;
J. 
Details and general notes.
Provisions shall be made to grant access for future development of un-platted adjacent land at intervals of not more than 1/4 mile. This applies to utilities as well as streets.
In the event it is deemed desirable to deviate from these subdivision standards, the engineer must submit, in writing, a request to the Village Engineer stating the degree of deviation and the reasons why such deviation is necessary or desirable. The deviation must be approved in writing by the Board of Trustees prior to the final design work and shall apply to that location and point in time only.
The subdivider shall complete the subdivision guarantee as specified herein. The form of the guarantee shall be as set forth in these documents or as approved by the Oakwood Village Attorney. The guarantee shall be in effect for a period of one year from the date of final acceptance of the subdivision improvements by the Village Board of Trustees. The guarantee shall be approved by the Board of Trustees or the Oakwood Village Attorney.
It shall be the duty of the certifying engineer to notify the Village Engineer at least one day in advance of any starting, suspended, resumption or completion of each phase of construction work. This section shall not apply to work suspended by reason of adverse weather conditions.
The degree of engineering inspection during actual construction operations shall be 100% during storm sewer, sanitary sewer, water main, force main, and pavement construction. The inspection shall be rendered by the developer's engineer or by a person working under the direction of the developer's engineer. All construction shall be executed in accordance with the approved engineering plans and specifications, with an inspector present as stated herein, or the Village Engineer shall stop all construction operations. Written periodic progress reports of construction, as compiled by the developer's engineer, will be required to be delivered to the Village Engineer.
After completion of the project and prior to acceptance by the Village Board of Trustees, the developer's engineer shall furnish the Village Engineer with three complete sets of record drawings that reflect the actual field conditions and data commensurate with how the improvements were constructed. In addition, the developer's engineer shall provide the Village Engineer with the AutoCAD or Microstation files of the development, order to allow the Village Engineer to readily update the Village Maps without redrawing the development. Each sheet of the record drawings shall be clearly marked "record drawing" and dated in the lower right-hand corner. Three copies of the approved final plat shall accompany these drawings.
