[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II)]
All improvements in divisions or developments shall be installed by the owner according to the following procedure:
A. 
The owner shall cause all construction plans, specifications and cost estimates to be prepared. The plans shall be prepared by a professional engineer registered in Wisconsin.
B. 
The Municipal Engineer shall review or have reviewed the construction plans, specifications and cost estimates for conformance with the requirements of the municipality, and shall approve, reject or conditionally approve, in writing, the proposed construction plans, specifications and cost estimates for conformance with the requirements of the municipality.
C. 
Unless the improvements are fully complete at the time of filing of the final plat, the owner shall supply the municipality with cash or an irrevocable letter of credit approved by the Municipal Attorney and the governing body in the amount of estimated cost of improvements and other fees as approved by the Municipal Engineer. If the improvements will be completed prior to the approval of the final plat, the financial guarantee may be in the form of a surety bond rather than cash or a letter of credit if applicable laws give the owner this option, provided that the surety bond must be in a form approved by the Municipal Attorney and amount approved by the Municipal Engineer. The Municipal Engineer may from time to time raise the amount of the estimated costs of said improvements. Within 30 days of written notice of said change, the owner shall increase the financial security by that amount or any other amount acceptable to the governing body. Reduction of the financial security for any purpose shall be made only after written approval of the Municipal Engineer and the governing body. As the required improvements are installed and accepted, the governing body may authorize reduction of the financial security in the amount deemed appropriate. No surety bonds will be accepted as financial security unless all work will be completed prior to the time of filing the final plat.
D. 
The owner shall supply the municipality with a list of contractors from whom the owner proposes to solicit proposals for the installation of the improvements. The list shall include prequalification statements from each proposed contractor. The governing body shall have the right to review said information and discuss it with the owner.
E. 
The owner shall enter into a contract with those contractors it may wish after submitting the information required in Subsection D above in a form satisfactory to the Municipal Engineer and after discussion of said information with the governing body.
F. 
After completion of all public improvements and prior to final acceptance of said improvements, the owner shall make or cause to be made a map showing the actual location of all valves, manholes, stubs, catch basins, sanitary sewer mains, storm sewer mains, water mains and such other facilities as the Municipal Engineer shall require. This map shall be prepared in black ink on reproducible drafting film 0.007 inch thick and shall bear the signature and seal of a professional engineer registered in Wisconsin. In addition to the above-described map, the owner shall provide the municipality with "valve cards" showing the locations of water main valves and hydrants and as-built working drawings of sewage lift stations, water pump house facilities and such other facilities as the Municipal Engineer may require. Manufacturers guarantees on equipment shall be furnished where in force. The presentation of the map, other as-built drawings, operating and maintenance manuals, and manufacturers guarantees shall be a condition of final acceptance of the improvements and release of the final payment.
Prior to the final road inspection, the owner shall provide the Municipal Engineer with a written certification from the owner's engineer or surveyor to the effect that the improvements conform to all municipal specifications and all plans previously filed and approved. Final inspection of road improvements shall be made a minimum of seven days after the surface course has been applied. Final acceptance of the improvements will be made only between May 1 and December 15 of any year.
