Code, and with the Jefferson County Sanitation Ordinance. Service laterals shall be provided to all lots served by public sewer.
[Amended 3-13-2019 by Ord. No. 1]
E. 
The subdivider shall pay all the costs of all sanitary sewer work, including the bringing of the sanitary sewer from where it exists to the subdivision in question, as well as providing all sanitary sewer work within the subdivision. 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 appropriate sanitary district serving the area.
A. 
The subdivider shall make adequate domestic water supplies available, and pay for such improvements, for each lot within the subdivision or land division in a designated urban service area.
B. 
The subdivider shall construct water mains in such a manner as to make adequate water service available to each lot within the subdivision or land division. The size, type, and installation of all public water mains proposed to be constructed shall be in accordance with plans and specifications approved by the appropriate sanitary district. Water service laterals shall be provided to all lots served by public sewer.
A. 
The subdivider must prepare a stormwater drainage plan containing the matters set forth in Subsection B that is approved by the Town and its engineer unless the Town waives such requirements in writing. The stormwater drainage plan may not be amended without the consent of the Town.
B. 
Pursuant to § 490-37, 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. Storm sewers are to be of adequate size and grade to hydraulically accommodate the ten-year storm; culverts shall be designed to accommodate the ten-year storm and shall be sized so that the twenty-five-year frequency storms do not cause flooding of the adjacent roadway. Upon the approval of the Town Engineer, stormwater swales and ditches may be sized for from twenty-five-year to one-hundred-year frequency storms, depending upon the estimated amount of damage that would be incurred by adjacent properties if flooding did occur. 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 Town Board, upon the recommendation of the Town Engineer. Storm sewers oversized to handle runoff from off-site properties will be installed by the subdivider; however, the cost of oversizing above a twenty-four-inch diameter storm sewer shall be paid by other users connecting to the system.
A. 
The subdivider shall cause gas, electric power and telephone facilities to be installed in such a manner as to make adequate service available to each lot in the subdivision, certified survey or land division. All new electrical distribution television cables and telephone lines from which lots are individually served shall be underground unless the Town Board specifically allows overhead poles for the following reasons:[1]
(1) 
Topography, soil, water table, solid rock, boulders, or other physical conditions would make underground installation unreasonable or impractical; or
(2) 
The lots to be served by said facilities can be served directly from existing overhead facilities.

Pursuant to the County's or Town's Construction Site Erosion Control Ordinance, the subdivider shall cause all gradings, excavations, open cuts, side slopes, and other land surface disturbances to be mulched, seeded, sodded or otherwise protected so that erosion, siltation, sedimentation and washing are prevented. The subdivider shall submit an erosion control plan that specifies measures that will be taken to assure the minimization of erosion problems.
When the land included in a subdivision plat or certified map abuts upon or is adjacent to land used for farming or grazing purposes, the subdivider shall erect, keep, and maintain partition fences, satisfying the requirements of the Wisconsin Statutes for a legal and sufficient fence, between such land and the adjacent land. A covenant binding the developer, its grantees, heirs, successors, and assigns to erect and maintain such fences, without cost to the adjoining property owners, so long as the land is used for farming or grazing purposes, shall be included upon the face of the final plat or certified survey map.
A. 
Utility easements. The Town Board, on the recommendation of appropriate agencies serving the Town, 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 chapter 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. The Town shall have access to the easement to maintain if the develop and/or property owner fail to.
[Amended 3-13-2019 by Ord. No. 1]
B. 
Drainage easements. Where a subdivision is traversed by a watercourse, drainage way, 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, drainage way, channel or stream may be relocated in such a manner that the maintenance of adequate drainage will be ensured 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 Town 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 12 feet wide, or wider where recommended by the Town Engineer, and may run across lots or alongside of rear lot lines. Such easements should preferably be located along rear lot lines. Evidence shall be furnished the Plan Commission and Town Board 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.
