D. 
Grades.
(1) 
Unless necessitated by exceptional topography, subject to the approval of the Plan Commission, the maximum center-line grade of any street or public way shall not exceed the following:
(a) 
Arterial streets: 6%.
(b) 
Collector streets: 8%.
(c) 
Minor streets, alleys and frontage streets: 10%.
(d) 
Pedestrianways: 12%, unless steps of acceptable designs are provided.
(2) 
The grade of any street shall in no case exceed 12% or be less than 0.5%.
(3) 
Street grades shall be established wherever practicable so as to avoid excessive grading, the promiscuous removal of ground cover and tree growth, and general leveling of the topography.
E. 
When a continuous street center line deflects at any one point by more than 10°, a circular curve shall be introduced having a radius of curvature on said center line of not less than the following:
(1) 
Arterial streets and highways: 500 feet.
(2) 
Collector streets: 300 feet.
(3) 
Minor streets: 100 feet.
F. 
Streets shall be laid out to provide for possible continuation wherever topographic and other physical conditions permit.
G. 
Minor streets shall be so laid out so as to discourage their use by through traffic.
H. 
The number of intersections of minor streets with major streets shall be reduced to the practical minimum consistent with circulation needs and safety requirements.
I. 
Where a subdivision abuts or contains an existing or proposed arterial highway, the Plan Commission shall require a frontage road, nonaccess reservation along the rear of the property contiguous to such highway, or such other treatment as may be necessary to ensure safe, efficient traffic flow and adequate protection of residential properties.
J. 
Reserve strips controlling access to streets shall be prohibited.
K. 
A tangent at least 100 feet long shall be required between reverse curves on arterial and collector streets.
L. 
Streets shall afford maximum visibility and safety and shall intersect at right angles, where practicable.
M. 
Dedication of half-width streets shall be prohibited.
N. 
Permanent dead-end streets or culs-de-sac shall not be longer than 1,000 feet, shall have a minimum width of 50 feet and terminate with a turnaround having an outside roadway diameter of at least 80 feet and a street property line of 100 feet.
O. 
Where possible, lot lines shall be perpendicular to the street line and to the tangent at the lot corner of curved streets.
P. 
Lots shall follow, rather than cross, municipal boundary lines whenever practicable.
Q. 
No street names shall be used which will duplicate or may be confused with the names of existing streets. Street names shall be subject to the approval of the Plan Commission.
A. 
The lengths, width and shapes of blocks shall be appropriate for the topography and the type of development contemplated.
B. 
To provide access and circulation to community facilities, sidewalks shall be provided by the subdivider, and, where a block exceeds 1,000 feet in length, a crosswalk through the center of blocks shall be provided. Center crosswalks shall not be less than 10 feet wide. These requirements may be waived by the Plan Commission as provided in § 445-49 of this chapter.
C. 
The Plan Commission may require that certain species of trees be planted on both sides of all streets.
D. 
Subdivision lots in the Village shall be in conformance with the area and width requirements of Chapter 510, Zoning. Area and width requirements of subdivision lots in the extraterritorial plat approval jurisdiction shall conform to town zoning ordinances and Ch. SPS 385, Wis. Adm. Code.[1]

A. 
Drainage system required. 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. 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 Village Engineer.
B. 
Drainage system plans.
(1) 
The subdivider shall submit to the Village Engineer and Village Board a 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. 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:
(a) 
Estimates of the quantity of stormwater entering the subdivision naturally from areas outside the subdivision.
(b) 
Quantities of flow at each inlet or culvert.
(c) 
Location, sizes and grades of required culverts, storm drainage sewers and other required appurtenances.
(2) 
A grading plan for the streets, blocks and lots shall be submitted by the subdivider for the area within the subdivision.
(3) 
The design criteria for storm drainage systems shall be based upon information provided by the Village Engineer.
(4) 
Material and construction specifications for all drainage projects (i.e., pipe, culverts, seed, sod, etc.) shall be in compliance with specifications provided by the Village Board or Village Engineer.
C. 
Grading. The subdivider shall grade each subdivision in order to establish street, block and lot grades in proper relation to each other and to topography as follows:
(1) 
The subdivider shall grade the full width of the right-of-way of all proposed streets in accordance with the approved plans.
(2) 
Block grading shall be completed by the subdivider, at his cost, by one or more of the following methods:
(a) 
A ridge may be constructed along the rear lot lines which provides for drainage onto the streets.
(b) 
Parts of all lots may be graded to provide for drainage to the street or to a ditch along the rear lot line.
(c) 
Draining across rear or side lot lines may be permitted, provided that drainage onto adjoining properties is skillfully controlled.
D. 
Drainage system requirements. The subdivider shall install all the storm drainage facilities indicated on the plans required in Subsection A of this section.
(1) 
Street drainage. All streets shall be provided with an adequate storm drainage system. The street storm system shall serve as the primary drainage system and shall be designed to carry street, adjacent land and building stormwater drainage. No stormwater shall be permitted to be run into the sanitary sewer system within the proposed subdivision.[1]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(2) 
Off-street drainage. The design of the off-street drainage system shall include the watershed affecting the subdivision and shall be extended to a watercourse or ditch adequate to receive the storm drainage. When the drainage system is outside of the street right-of-way, the subdivider shall make provisions for dedicating an easement of the Village to provide for the future maintenance of said system. Easements shall be a minimum of 20 feet, but the Village may require larger easements if more area is needed due to topography, size of watercourse, etc.
E. 
Protection of drainage systems. The subdivider shall adequately protect all ditches to the satisfaction of the Village Board and Village Engineer. Ditches and open channels shall be seeded, sodded or paved depending upon grades and soil types. (Generally, ditches or channels with grades up to 1% shall be seeded, those with grades up to 4% shall be sodded, and those with grades over 4% shall be paved.)
