A. 
Central sanitary sewerage and private sewage disposal systems.
1. 
The subdivider shall construct sanitary sewers in such a manner as to make adequate sanitary sewerage service available to each lot within the subdivision. If central sewer facilities are not available, the subdivider shall make provision for adequate private sewage disposal systems as specified by the community Wisconsin Department of Natural Resources; however, any lot containing less than one acre of land and being less than 150 feet wide must be served by public sanitary sewer facilities, unless in the considered opinion of the Plan Commission such service will be made available to the subdivision within five years of the date of the submission of the preliminary plat. The City Plan Commission may require the installation of sewer laterals to the street lot line. If, at the time of final platting, sanitary sewer facilities are not available to the plat, but will become available within a period of five years from the submission of the preliminary plat, the subdivider shall install or cause to be installed sanitary sewers and sewer laterals to the street lot line in accordance with this section and shall cap all laterals as may be specified by the City Engineer. The size, type and installation of all sanitary sewers proposed to be constructed shall be in accordance with plans and standard specifications approved by the City Engineer. All sanitary sewer facilities shall be floodproofed.
2. 
The subdivider shall assume the cost of installing all sanitary sewers 10 inches in diameter or less in size. If greater than ten-inch-diameter sewers are required to handle the contemplated sewage flows, the cost of the materials only of such larger sewers shall be reimbursed by the City to the subdivider. The subdivider shall pay all costs associated with installation of sewer.
B. 
Water supply facilities.
1. 
The subdivider shall construct water mains in such a manner as to make adequate water service available to each lot within the subdivision. If municipal water service is not available, the subdivider shall make provision for adequate private water systems as specified by the Wisconsin Department of Natural Resources; however, any lot containing less than one acre of land and being less than 150 feet wide must be served by public water facilities, unless in the considered opinion of the Plan Commission such services will be made available to the subdivision within five years of the date of the submission of the preliminary plat. The Plan Commission may require the installation of water laterals to the street lot line. The size, type and installation of all public water mains proposed to be constructed shall be in accordance with plans and standard specifications approved by the City Engineer.
2. 
The subdivider shall assume the cost of installing all water mains 10 inches in diameter or less in size. If greater than ten-inch water mains are required, the City shall reimburse the developer for the difference in cost of materials only between the ten-inch water main and the larger size water main. The subdivider shall pay all costs associated with the installation of mains no matter what size. All water systems shall be floodproofed.
3. 
If oversized materials and equipment are required to obtain adequate flows when developing at higher elevations such as the bluffs, the subdivider/developer shall be required to pay for all oversized materials and equipment, including but not limited to booster stations and oversized water mains.
A. 
Pursuant to Section 13.04.31, the subdivider shall provide stormwater drainage facilities which may include curb and gutter, catch basins and inlets, storm sewers, road ditches and open channels, as may be required. All such facilities are to be of adequate size and grade to hydraulically accommodate maximum potential volumes of flow, the type of facility required, the design criteria and the sizes and grades to be determined by the City Engineer. Storm drainage facilities shall be so designed as to present no hazard to life or property, minimize shoreland erosion and siltation of surface waters, shall prevent excess runoff on adjacent property and shall provide positive drainage away from on-site sewage disposal facilities. The size, type and installation of all stormwater drain and sewers proposed to be constructed shall be in accordance with this section and plans and standard specifications approved by the City Engineer. Storm drainage facilities shall be so designed as to minimize hazards to life or property, and the size, type and installation of all stormwater drains and sewers proposed to be constructed shall be in accordance with the plans and specifications approved by the City Engineer. The subdivider, at their cost, shall comply with Federal Stormwater Regulations and the State of Wisconsin Department of Natural Resources NR 216 using NR 151 performance standards. The subdivider shall submit a stormwater management plan as outlined in the City of Onalaska Erosion Control and Stormwater Management Requirements.[1] The size, type, quantity of all stormwater controls and best management practices shall be reviewed for approval by the City Engineer.

As required by the City of Onalaska Erosion Control and Stormwater Management Requirements, a drainage system shall be designed and constructed by the subdivider to provide for the proper drainage of the surface water of the subdivision and the drainage area of which it is a part. The drainage system shall adhere to the requirements as outlined in the City of Onalaska Erosion Control and Stormwater Management Requirements. A final plat shall not be approved until the subdivider shall submit plans, profiles and specifications as specified in this section, which have been prepared by a registered professional engineer and approved by the Common Council, upon the recommendations of the Plan Commission and City Engineer.
2. 
Associated permits. Applicants must also apply for and receive stormwater and erosion control permits when applicable. Applicants shall conform to standards set forth in the City of Onalaska Erosion Control and Stormwater Management Requirements.
3. 
Drainage system plans.
a. 
The subdivider shall submit to the City at the time of filing a preliminary plat a preliminary drainage plan, and engineering report on the ability of existing watercourse channels, storm sewers, culverts and other improvements pertaining to drainage or flood control within the subdivision to handle the additional runoff which would be generated by the development of the land within the subdivision. The drainage plan and engineering report shall adhere to the requirements as outlined in the City of Onalaska Erosion Control and Stormwater Management Requirements. Additional information shall be submitted to adequately indicate that provision has been made for disposal of surface water without any damage to the developed or undeveloped land downstream or below the proposed subdivision. The report shall also include:
i. 
Estimates of the quantity of stormwater entering the subdivision naturally from areas outside the subdivision.
ii. 
Quantities of flow at each inlet or culvert.
iii. 
Location, sizes and grades of required culverts, storm drainage sewers and other required appurtenances.
b. 
A grading plan for the streets, blocks and lots shall be submitted by the subdivider for the area within the subdivision.
c.

4. 
Storm drainage and stormwater management facilities.
a. 
The subdivider, at their cost, shall install all drainage and stormwater management facilities identified in the drainage plan, engineering report and Erosion Control Plan or determined by the City Engineer as being necessary for the management of all lands and roadways within the development. In addition, drainage capacity through the development from other areas shall be provided in accordance with a Comprehensive Surface Water Management Study, if applicable. All required storm drainage facilities shall be constructed and operational prior to acceptance of any dedications and/or public improvements served by the storm drainage facilities.
b. 
The subdivider shall submit to the City Engineer for review and approval a final copy of the drainage plan and engineering report, including as-built data, as outlined in the City of Onalaska Erosion Control and Stormwater Management Requirements, prior to any final plat approval.
A. 
Utility easements. The Common Council, on the recommendation of appropriate departments and agencies serving the City, shall require utility easements for poles, wire, conduits, storm and sanitary sewers, gas, water and head mains or other utility lines. It is the intent of this section to protect all established easements so as to assure proper grade, assure maintenance of the established grade, prohibit construction of permanent fences or retaining walls over underground installation and prevent the planting of trees in the easement area.
B. 
Drainage easements. Where a subdivision is traversed by a watercourse, drainageway, channel or stream:
1. 
There shall be provided a stormwater easement or drainage right-of-way conforming substantially to the lines of such watercourse and such further width or construction, or both, as will be adequate for the purpose and as may be necessary to comply with this section; or
2. 
The watercourse, drainageway, channel or stream may be relocated in such a manner that the maintenance of adequate drainage will be assured and the same provided with a stormwater easement or drainage right-of-way conforming to the lines of the relocated watercourse, and such further width or construction, or both, as will be adequate for the purpose and may be necessary to comply with this section.
3. 
Wherever possible, it is desirable that drainage be maintained by an open channel with landscaped banks and adequate width for maximum potential volume flow. In all cases, such watercourse shall be of a minimum width established at the high-water mark or, in the absence of such specification, not less than 30 feet. If, in the opinion of the City Engineer, the easement will be for a major drainage swale, the easement shall be of sufficient width to contain a one-hundred-year-frequency storm. If the drainage easement is located in an established floodway or flood-fringe district, the entire floodplain area shall be included within the drainage easement.
C. 
Easement locations. Such easements shall be at least 10 feet wide, or wider where recommended by the City Engineer, and may run across lots or alongside of front lot lines. Such easements should preferably be located along front lot lines. Evidence shall be furnished the Plan Commission and Common Council that easements and any easement provisions to be incorporated in the plat or in deeds have been reviewed by the individual utility companies or the organization responsible for furnishing the services involved.
A. 
When any public improvements of adequate capacity are not available at the boundary of a proposed land division, the City, or its duly authorized representative, shall require, as a prerequisite to approval of a final plat or Certified Survey Map, assurances that such improvement extensions shall be provided as follows in accordance with the following standards:
1. 
Design capacity. All improvements within or entering or leaving the proposed development shall be installed to satisfy the service requirements for the entire service or drainage area in which the development is located and the improvements shall be of sufficient capacity to handle the expected development of the overall service area involved.
2. 
Extra-sized and off-size improvements. Where improvements of adequate size needed to serve the development are not available at the boundary of the development, the subdivider shall proceed under one of the alternatives as identified in Section 6.03.21.B.
3. 
Lift stations. Where sanitary or storm sewer lift stations and force mains are required to lift sewage to the gravity system, the subdivider shall have plans, profiles, specifications and estimated operation and maintenance costs prepared for the installation of such facilities to the City Engineer's requirements. Equipment similar to existing City equipment shall be utilized whenever possible. The installation, inspection, supervision and engineering fees for lift stations and/or force mains shall be paid for by the subdivider unless otherwise determined and agreed upon by the Common Council. Gravity sanitary sewer service shall be employed whenever determined by the City Engineer to be feasibly accessible.
