Town of Oconomowoc, WI Required Improvements

Prior to final approval by the Town Board, the subdivider will provide and dedicate the following facilities and improvements, all of which facilities and improvements must be installed or provided for within the time required by the Town Board:

(1)

Streets graded and surfaced according to the Town road standards adopted by the Town Board.

(2)

Drainage ditches, culverts, and such other facilities necessary to provide adequately for surface water and stormwater drainage according to the standards set forth in Article VII of this chapter, so as to prevent excessive surface water runoff, sedimentation and erosion from occurring on downstream lands, rivers, streams, lakes and other natural watercourses. The Town Board may require that such protective measures be taken within a reasonable period of time after completion of the grading of the development. The method of treatment shall be in accordance with the standards of the Soil Conservation Service Technical Guide and as may be ordered by the Town Board. The Town Board may also require the size of all culverts to be utilized by the future lot owners of the development to be noted on a copy of the final plat to be submitted to the Town Clerk and Building Inspector. This information does not need to be placed upon the original final plat or certified survey map to be recorded.

(3)

Facilities for distribution of electric, telephone and gas utility service located within a subdivision shall be installed underground except where the Town Board, upon recommendation of the Town Plan Commission, find that adverse soil conditions or problems of utility distribution make such installation prohibitively expensive or impractical. Transformer junction boxes, meter points or similar equipment may be installed upon the ground surface. Any landscape screening plan required for such aboveground equipment shall be submitted to the utility for approval.

(4)

Street signs shall be erected by the subdivider at all intersections and shall be of a standard design approved by the Town.

(5)

Fire protection water tank requirements.

(a)

Water reservoir requirements. Developers shall provide emergency water reservoirs of fiberglass construction for fire protection purposes within subdivisions as follows:

Subdivision Size (including certified survey maps) (number of lots)	Number of Reservoirs Required	Size of Reservoir (gallons)
0 to 10	1	10,000 (not mandatory; required at the discretion of the Plan Commission after receiving the recommendation of the Fire Chief)
11 to 39	1	10,000
40 to 79	2	10,000
80 to 120	3	10,000

(b)

Location. Tanks shall be located in Town road rights-of-way but not in culs-de-sac. The location of the tanks shall be specified by the Chief of the Fire Department which protects the fire district in which the subdivision is located.

(c)

Specifications. See the diagram which is on file in the Town Clerk's office and is available for inspection.

[1]

Pea gravel bedding will be utilized for backfilling and for base.

[2]

Any used tank will be hydrostatically tested and coated on the outside of the tank according to NFPA standards.

[3]

The drafting/suction pipe height above the finished roadway surface shall be 24 inches to the center line of the elbow fitting of the six-inch pipe with a four-and-one-half-inch adapter.

[4]

The drafting pipe shall extend to within 12 inches of the bottom of the tank. The length of the draft pipe should be kept to a minimum after meeting the requirements of Subsection E(3)(c). The drafting pipe shall be six inches in diameter and shall terminate with an elbow to accept the four-and-one-half-inch hydrant fitting with cap and chain.

[5]

A screened, four-inch vent pipe with the opening facing downward will be included in all tanks. The vent pipe shall be a minimum of 24 inches above the finished roadway surface. The vent pipe shall have a two-inch capped inspection pipe located at the top.

[6]

A four-inch fill pipe with elbow will be provided at each tank by the installer which terminates 24 inches above the finished roadway surface, measured at the pipe with two-and-one-half-inch Siamese Y with cap and chain.

[7]

The maximum distance from the road edge to the drafting pipe shall not exceed nine feet. This will allow a fire pumper, positioned on the finished road surface using one section of standard hard suction hose, to easily reach the draft pipe. As an alternative, the developer may provide a paved apron adjacent to the roadway adequate for the parking of Fire Department apparatus.

[8]

All aboveground piping shall be primed and then painted red for suction with a four-and-one-half-inch adapter, white for vent, and yellow for fill, by the installer before the tank is approved for service and filled.

[9]

The contractor installing the tank shall also install a "no parking" sign at a location specified by the Fire Department. The sign and installation shall be at the expense of the subdivider.

[10]

The installation shall be made with consideration of the winter temperatures. Steps will be taken to ensure the piping and water in the tank will not freeze during extended periods of below-zero weather.

(d)

Administration.

[1]

Inspections. The developer or the installer shall notify the Building Inspector for purposes of inspection before backfilling. The developer or the installer of the water tank shall notify the Fire Department protecting the fire district in which the subdivision is located of completion of the installation for purposes of inspection. Forty-eight-hour notification shall be provided, and a fee of $25 shall be submitted to the Fire Department to cover the cost of inspection. All new or upgraded installations shall require inspection. Once approved, tanks shall be filled by the Fire Department. Water tank inspection forms may be obtained from the Town Clerk or Fire Department protecting the district.

[2]

The subdivider or contractor installing the tank shall post with the Town a bond in the amount of $1,000, to be held by the Town until the tank has received final Fire Department approval.

[3]

Any municipal or private fire department may utilize the water tank for fire protection purposes. All tanks shall be refilled by the department making use of the water. Refilling shall be accomplished as soon as possible.

[4]

The Fire Department having fire protection responsibility for the district in which the subdivision is located shall inspect the water tanks in the spring and fall of each year.

If the above facilities and improvements have not been fully installed at the time the plat is submitted to the Town for final approval, the subdivider shall file with the Town Clerk a surety bond or other financial guarantee deemed adequate by recommendation of the Attorney, Plan Commission and/or Town Engineer and approved by the Town Board, to adequately cover the cost of completing such facilities and improvements.

All other improvements to be installed shall be at the direction of the Town Board or in accordance with any other ordinance in effect.

The adequacy of such facilities and improvements and their proper installation shall be subject to review by the Town Plan Commission, Engineer and Attorney and approval of the Town Board prior to approval of the final plat.

Construction or installation of improvements shall not commence until the preliminary plat and the construction plans have been approved by all agencies having authority to review the plat. All work or improvements to the subdivision shall also be subject to inspection by the Town Engineer to determine conformance with any applicable requirements.
