[Ord. No. 599, § 1(11-111), 5-6-1997]
(a) 
In general. In any new subdivision, the street, block, and lot layouts shall conform to the arrangement, width and location indicated on the official map, highway width map, comprehensive plan, or component neighborhood development plan of the Village, and shall be so designed as to be within the capability of the land and water resources; least disturb the existing terrain, flora, fauna, and water regimen; and meet all the use, site, sanitary, floodland, and shoreland regulations contained in the Village zoning and Waukesha County Sanitary Ordinance. In areas where such plans have not been completed, the street layout shall recognize the functional classification of the various types of streets, and shall be developed and located in proper relation to existing and proposed streets, to the topography, to such natural features as streams and tree growth, to public convenience and safety, to the proposed use of the land to be served by such streets, and to the most advantageous development of adjoining areas. The subdivision shall be designed so as to provide each lot with satisfactory access to a public street.
(b) 
Arterial streets. Arterial streets, as defined, shall be arranged so as to provide ready access to centers of employment, centers of governmental activity, community shopping areas, community recreation, and points beyond the boundaries of the community. They shall also be properly integrated with and related to the existing and proposed system of major streets and highways, and shall be, insofar as practicable, continuous and in alignment with existing or planned streets with which they are to connect. The width of the right-of-way shall be at the Village's discretion.
(c) 
Collector streets. Collector streets, as defined, shall be arranged so as to provide ready collection of traffic from residential areas and conveyance of this traffic to the major street and highway system, and shall be properly related to the mass transportation system, to special traffic generators such as schools, churches, shopping centers, and other concentrations of population, and to the major streets into which they feed. The right-of-way width shall be a minimum of 80 feet.
(d) 
Minor streets. Minor streets, as defined, shall be arranged to conform to the topography, to discourage use by through traffic, to permit the design of efficient storm and sanitary sewerage systems, and to require the minimum street area necessary to provide safe and convenient access to abutting property. The right-of-way shall be a minimum of 66 feet.
(e) 
Proposed streets. Proposed streets shall extend to the boundary lines of the tract being subdivided unless prevented by topography or other physical conditions, or unless, in the opinion of the Village Board and upon recommendation of the planning commission, such extension is not necessary or desirable for the coordination of the layout of the subdivision, or for the advantageous development of the adjacent tracts.
(f) 
Arterial street and highway protection. Whenever the proposed subdivision contains or is adjacent to a major street or highway, adequate protection of residential properties, limitation of access, and separation of through and local traffic shall be provided by reversed frontage, with screen planting contained in a nonaccess reservation along the rear property line, or by the use of frontage streets.
(g) 
Stream and lake shores. Public access shall be provided to all navigable stream and lake shores. Such access shall be at least 100 feet in width, platted to the low water mark at intervals of not more than one-half mile, except where greater intervals and wider access is agreed upon by the planning commission, or the department of natural resources. All platted public access shall have access to public, street, highway, parkway, or other public way.
(h) 
Reserve strips. Reserve strips shall not be provided on any plat to control access to streets or alleys, except where control of such strips is placed with the Village under conditions approved by the planning commission.
(i) 
Alleys. Alleys may be provided in commercial or industrial districts for off-street loading and service access but shall not be approved in residential districts. Dead-end alleys shall not be approved and alleys shall not connect to a major thoroughfare.
(j) 
Street names. Street names shall not duplicate or be similar to existing street names and existing street names shall be projected wherever possible.
[Ord. No. 599, § 1(11-112), 5-6-1997]
(a) 
Whenever the proposed subdivision contains or is adjacent to a limited access highway or railroad right-of-way, the design shall provide the following treatment:
(1) 
When lots within the proposed subdivision back upon the right-of-way of an existing or proposed limited access highway or railroad, a planting strip at least 30 feet in depth shall be provided adjacent to the highway or railroad, in addition to the normal lot depth. This strip shall be part of the platted lots but shall have the following restriction lettered upon the face of the plat: "This strip is reserved for the planting of trees and shrubs, the building of structures hereon prohibited."
(2) 
Commercial and industrial districts shall have provided, on each side of the limited access highway or railroad, streets approximately parallel to and at a suitable distance from such highway or railroad, for the appropriate use of the land between such streets and highway or railroad, but not less than 150 feet.
(3) 
Streets parallel to a limited access highway or railroad right-of-way, when intersecting a major street and highway or collector street which crosses said railroad or highway, shall be located at a minimum distance of 250 feet from said highway or railroad right-of-way. Such distance, where desirable and practicable, shall be determined with due consideration of the minimum distance required for the future separation of grides by means of appropriate approach gradients.
(4) 
Minor streets immediately adjacent and parallel to railroad rights-of-way shall be avoided, and location of minor streets immediately adjacent to arterial streets and highways and to railroad rights-of-way shall be avoided in residential areas.
[Ord. No. 599, § 1(11-113), 5-6-1997]
(a) 
Minimum widths. The minimum right-of-way and roadway width of all proposed streets and alleys shall adhere to the standard specifications adopted in the "Development Requirements: Curb and Gutter, Sidewalk, Pavement, and Landscaping" (including current updates) of the Village of Mukwonago. A copy of these standard specifications may be obtained from the Village Clerk or Building Inspector.
(b) 
Cul-de-sac streets. Cul-de-sac streets designed to have one end permanently closed shall adhere to the standard specifications adopted in the "Development Requirements" (including current updates) of the Village of Mukwonago. The right-of-way shall be 120 feet and the pavement shall have a radius of 45 feet. A copy of these standard specifications may be obtained from the Village Clerk or Building Inspector.
(c) 
Street grades. Unless necessitated by exceptional topography, subject to the approval of the planning commission, the maximum centerline grade of any street or public way shall not exceed the standard specifications adopted in the "Development Requirements" (including current updates) of the Village of Mukwonago. A copy of these standard specifications may be obtained from the Village Clerk or Building Inspector.
(d) 
Radii of curvature. When a continuous street centerline deflects at any one point by more than 10°, a circular curve shall be introduced having a radius of curvature in accordance with the standard specifications adopted in the "Development Requirements" (including current updates) of the Village of Mukwonago. A copy of these standard specifications may be obtained from the Village Clerk or Building Inspector.
(e) 
Half streets. Where an existing dedicated or platted half-street is adjacent to the tract being subdivided, the other half of the street shall be dedicated by the subdivider. The platting of half-streets should be avoided where possible.
(f) 
Floodlands. The elevations of roadways passing through floodland areas shall be in accordance with the standard specifications adopted in the "Development Requirements" (including current updates) of the Village of Mukwonago. A copy of these standard specifications may be obtained from the Village Clerk or Building Inspector.
(g) 
Waterway openings. Waterway openings of all new bridges and culverts carrying arterial streets over perennial streams shall be in accordance with the standard specifications adopted in the "Development Requirements" (including current updates) of the Village of Mukwonago. A copy of these standard specifications may be obtained from the Village Clerk or Building Inspector.
[Ord. No. 599, § 1(11-114), 5-6-1997]
(a) 
In general. Streets shall intersect each other as nearly to right angles as topography and other limiting factors of good design permit.
(b) 
Number of streets. The number of streets converging at one intersection shall be reduced to a minimum, preferably not more than two.
(c) 
Number of intersections. The number of intersections along major streets and highways shall be held to a minimum. Wherever practicable, the distance between such intersections shall not be less than 1,200 feet.
(d) 
Property lines. Property lines at street intersections shall be rounded with a minimum radius of 15 feet or a greater radius when required by the planning commission, or shall be cut off by a straight line through the points of tangency of an arc having a radius of 15 feet.
(e) 
Minor streets. Minor streets shall not necessarily continue across arterial or collector streets. However, if the centerlines of such minor streets approach the major streets from opposite sides within 300 feet of each other, measured along the centerline of the arterial or collector street, then the location shall be so adjusted that the adjoinment across the major or collector street is continuous and a jog is avoided.
[Ord. No. 599, § 1(11-115), 5-6-1997]
(a) 
In general. The widths, lengths, and shapes of blocks shall be suited to the planned use of the land, zoning requirements, need for convenient access, control and safety of street traffic, and the limitations and opportunities of topography.
(b) 
Lengths. As a general rule, blocks in residential areas shall not be less than 600 feet nor more than 1,500 feet in length, unless otherwise dictated by exceptional topography or other limiting factors of good design.
(c) 
Pedestrian ways. Where deemed necessary by the planning commission, pedestrian ways of not less than 10 feet in width may be required between rear lot lines in order to provide safe and convenient pedestrian circulation between the individual lots, streams, lakeshores, parklands, or other public areas. Where deemed essential by the planning commission, such ways may be required near the center and entirely across any block over 900 feet in length in order to provide adequate pedestrian circulation or access to schools, shopping centers, churches, or transportation facilities.
(d) 
Width. Blocks shall have sufficient width to provide for two tiers of lots of appropriate depth, except where otherwise required to separate residential development from through traffic. Width of lots or parcels reserved or laid out for commercial or industrial use shall be adequate to provide for off-street service and parking required by the use contemplated and the area zoning restrictions for such use.
(e) 
Utility easements. All utility lines for electric power and telephone service shall be placed on mid-block easements along rear lot lines whenever carried by overhead poles, except when such lots border a lake or stream.
[Ord. No. 599, § 1(11-116), 5-6-1997]
(a) 
In general. The size, shape, and orientation of lots shall be appropriate for the location of the subdivision, and for the type of development and use contemplated. The lots should be designed to provide an aesthetically pleasing building site and a proper architectural setting for the buildings contemplated.
(b) 
Side lot lines. Side lot lines shall be at right angles to straight street lines or radial to curved street lines on which the lots face. Lot lines shall follow municipal boundary lines rather than cross them.
(c) 
Access. Every lot shall front or abut on a public street for the required distance for the district in which it is located.
(d) 
Area and dimensions. The area and dimensions of all lots shall conform to the requirements of the Village zoning ordinance.
(e) 
Depth. Lots shall meet the minimum depth requirements for the district in which they are located. Excessive depth in relation to width shall be avoided and a proportion of two to one (2:1) shall be considered a desirable ratio under normal conditions.
(f) 
Lands between the meander line and waters edge. Lands lying between the meander line and the water's edge, and any otherwise unplattable lands which lie between a proposed subdivision and the water's edge, shall be included as part of lots, outlots, or public dedications in any plat abutting a stream or lake.
[Ord. No. 599, § 1(11-117), 5-6-1997]
Building setback lines shall conform to the requirements of the Village zoning ordinance.
[Ord. No. 599, § 1(11-118), 5-6-1997]
(a) 
In general. The planning commission may require utility easements of widths deemed adequate for the intended purpose on each side of all rear lot lines and on side lot lines, or across lots where necessary or advisable for electric power and communication poles, wires, conduits, storm and sanitary sewers, and gas, water, and other utility lines.
(b) 
Drainage easements. Where a subdivision is traversed by a drainageway or stream, an adequate easement shall be provided as may be required by the planning commission. The location, width, alignment, and improvement of such drainageway or easement shall be subject to the approval of the Village Engineer, and parallel streets or parkways may be required in connection therewith. Where necessary stormwater drainage shall be maintained by landscaped open channels of adequate size and grade to hydraulically accommodate maximum potential volumes of flow. Such channels are subject to review and approval by the Village Engineer.
(c) 
Where public utility easements exist on private property, the Village shall not permit encroachment upon said easements or the use of any portion of the easement by private property owners absent the consent of the Utility Director, the Director of Public Works or the Village Board. The encroachment shall not include any aboveground structures, landscaping or improvements except for at-grade pavement, gravel, pavers or other materials to improve access to the applicant's property across the easement. If such approval is granted, the party seeking to encroach upon the public easement or to make use of said property shall be required to enter into a license agreement with the Village in a form acceptable to the Village Attorney. The licensee shall be required to indemnify and hold harmless the Village of Mukwonago as and against any and all claims, demands, actions or causes of action, including actual attorney fees, that may result from the approval of the license. The licensee shall further be required to provide evidence annually that the licensee, its agents, contractors, subcontractors and assigns, has public liability insurance with limits of not less than $1,000,000 per occurrence and $2,000,000 in the aggregate, which insurance names the Village of Mukwonago as an additional insured on a primary and noncontributory basis. The licensee shall be required to further indemnify the Village, as licensor, for any costs or expenses incurred by the Village as a result of the impact of the license on the public utilities, as well as the costs of any damages to public utilities arising from the exercise of the rights under the license. The Village shall have the right to repair, maintain and/or reconstruct the public utilities within the easement, and should that work result in any disturbance of improvements made by the licensee on the property, the cost of the restoration of the improvements shall solely be the responsibility of the licensee. The Village Utility Director may require such additional provisions as may be appropriate given the individual circumstance of the particular license request to protect and preserve public assets. If any of the terms or conditions of the license agreement are not followed, the agreement shall be considered to be breached and may be terminated by the Village. The license agreement shall be recorded with the Register of Deeds of the County in which the property is located and for which the license is given.
