[Prior code § 18.11(13)]
A. 
Underground Requirements.
1. 
All new electric distribution lines, all new telephone lines from which individual lots are served, community antenna television cables and services, and gas utility services shall be underground unless the Plan Commission shall find upon study that:
a. 
The placing of such facilities underground would not be compatible with the development; or
b. 
Location, topography, soil, swamp, solid rock, boulders, stands of trees, rows of trees, hedges or other physical conditions would make underground installation unreasonable or impracticable.
2. 
Associated equipment and facilities such as, but not limited to, substations, pad-mounted transformers, pad-mounted sectionalizing switches and pedestal-mounted terminal boxes, may be located above ground, provided that they are located in an inconspicuous manner, screened from public view and fit into the development plans for the subdivision.
3. 
The subdivider or his or her agent shall furnish proof to the Plan Commission that such arrangements as may be required under applicable rates and rules filed with the Public Service Commission of the state of Wisconsin have been made with the owners of such lines or services for placing their respective facilities underground as required by this section, as a condition precedent to approval of the final plat, development plan or certified survey map.
4. 
Temporary overhead facilities may be installed to serve a construction site or where necessary because of severe weather conditions. In the latter case, within a reasonable time after weather conditions have moderated or upon completion of installation of permanent underground facilities, such temporary facilities shall be replaced by underground facilities and the temporary facilities removed.
B. 
Easement Conditions.
1. 
Adequate easements shall be provided and dedicated on each side of all rear lot lines, and on side lot lines, across lots, or along front lot lines where necessary, for the installation of storm and sanitary sewers, gas, water, electric lines and communication lines. Such easements shall be noted as "Utility Easements" on the final plat or certified survey map. Prior to approval of the final plat, the specific implementation plan for a planned unit development (PUD), the comprehensive development plan, or certified survey map, concurrence of the appropriate electric and gas communications companies as to the location and width of the utility easements shall be noted on the final plat, specific implementation plan for the PUD, comprehensive development plan, or certified survey map. All easements for storm and sanitary sewers, water mains, pedestrian walks and other public purposes shall be noted thereon as "Public Easements or" followed by reference to the use for which they are intended.
2. 
Where the electric and gas communications facilities are to be installed underground, the utility easements shall be graded to within six inches of final grade by the subdivider, prior to the installation of such facilities, and earth fill, piles or mounds of dirt shall not be stored on such easement areas. Utility facilities when installed on utility easements whether overhead or underground shall not disturb any monumentation in the plat. In cases where monumentation is disturbed, the utility shall bear the cost of replacement. Failure to comply will be subject to penalty as provided in Section 236.32, Wisconsin Statutes.
3. 
Where the electric and gas communications facilities are to be installed underground, a plat restriction shall be recorded with the final plat or certified survey map stating that the final grade established by the subdivider on the utility easements shall not be altered by more than six inches by the subdivider, his or her agent, or by subsequent owners of the lots, except with written consent of the utility or utilities involved. The purpose of this restriction shall be to:
a. 
Notify initial and future lot owners of the underground facilities at the time of purchase;
b. 
Establish responsibility in the event of damage to such facilities; and
c. 
Establish the need to alter such facilities. When the utility company uses a service application, the application should also notify the initial and subsequent lot owners of their responsibility regarding such underground facilities.
[Prior code § 18.11(14)]
A. 
Greenways and environmental corridors included within land to be divided shall receive the following prescribed treatment by the owner of the subdivision. Where a subdivision is traversed by a waterway, drainage way, channel or stream, or mapped greenway/environmental corridor, an adequate drainage way or easement shall be provided as required by the Plan Commission conforming substantially with the line of such watercourse. The location, width, alignment and improvement of such drainage way or easement shall be subject to the approval of the Plan Commission. Parallel streets or parkways may be required. Storm water drainage shall be maintained by landscaped open channels of adequate size and grade to accommodate the flow resulting from the one-hundred-year rainfall event of any duration, such sizes and design details to be subject to review and approval by the Village Engineer.
B. 
The subdivider shall be responsible for an acceptable continuous drainage way through the proposed plat as determined by the Village Engineer. The subdivider shall furnish the Village Engineer with a plan outlining the greenway/environmental corridor boundaries and the location of existing drainage ways. Such areas shall be dedicated or reserved as required by Section 16.08.010(E). In addition, the subdivider shall furnish to the Village Engineer a set of cross sections (on fifty foot stations) of the greenway based on Village datum oriented upon a base line as prescribed by the Village Engineer. Where a natural drainage way exists which has acceptable hydraulic capacities including alignment and grade as determined by the Village Engineer, construction will not be required and the existing natural growth shall be preserved. Where such natural growth is not preserved by action of the subdivider or his or her agents, he or she shall be responsible for repairing the disturbed areas by returning them to the original condition by methods approved by the Village Engineer. When it is determined by the Village Engineer that the hydraulic capacities including alignment and grade are not acceptable, then such alignment, grade and slopes shall be improved by the subdivider to the cross section specified by the Village Engineer.
C. 
The subdivider shall install permanent pipes or culverts at a grade designated by the Village Engineer under all streets crossing a greenway or drainage way. The installation shall be in accordance with the state of Wisconsin Specifications for Road and Bridge Construction. Culverts required across intersections for temporary street drainage shall be furnished and installed by the developer. All temporary culverts installed by the developer shall be completely removed when the streets are constructed to Village standards and the area restored to as nearly original condition as possible, as determined by the Village Engineer.
D. 
In order to assure proper drainage, the ground elevation along any lot line common with the boundary of a greenway/environmental corridor shall be to an elevation approved by the Village Engineer. All lot grading and building elevations shall provide for positive drainage. Grading or filling within the greenway/environmental corridor limits is prohibited.
E. 
Greenways/environmental corridors shall be limited to public uses.
