(B) Cul-de-sac streets designed to have one end permanently closed shall not exceed 500 feet in length. All cul-de-sac streets designed to have one end permanently closed shall terminate in a circular turnaround having a minimum right-of-way radius of 66 feet and a minimum back of curb radius of 47.5 feet or 45 feet for rural cross-section streets.
(C) Temporary termination of streets at the boundary of a subdivision that are intended to be extended at a later date and where more than four dwelling units have driveway access to such street, or when the nearest intersection to the boundary of the subdivision is greater than 200 feet, shall be accomplished with a temporary cul-de-sac in accordance with the standards set forth above or by construction of a temporary “T” turnaround having a crossbar paved width of at least 22 feet and a length of 60 feet, with the option subject to the approval of the Plan Commission and the Village Board.
(D) Unless necessitated by exceptional topography subject to the approval of the Plan Commission, the maximum centerline grade of any street or public way shall not exceed the following:
(1) Arterial streets: 6%;
(2) Collector streets: 8%;
(3) Local streets, alleys, and frontage streets: 10%;
(4) Pedestrian ways: 10%, unless steps of acceptable design are provided; and
(5) The grade of any street shall in no case exceed 10% or be less than 0.5%.
(E) 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 topography. All changes in street grades shall be connected by vertical curves of a minimum length equivalent in feet to 15 times the algebraic difference in the rates of grade for all major streets, and one-half this minimum for all other streets.
(F) (1) When a continuous street centerline deflects at any one point by more than ten degrees, a circular curve shall be introduced having a radius of curvature on said centerline of not less than the following:
(a) Arterial streets and highways: 500 feet;
(b) Collector streets: 300 feet; and
(c) Local streets: 100 feet.
(2) A tangent at least 100 feet in length shall be provided between reserve curves on arterial and collector streets.
(G) Where, on the date of enactment of this chapter, 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 is not permitted.
(Prior Code, § 18.08)
(A) Streets shall intersect each other at as nearly right angles as topography and other limiting factors of good design permit.
(B) In addition:
(1) The number of streets converging at one intersection shall be reduced to a minimum, preferably not more than two;
(2) The number of intersections along arterial streets and highways shall be held to a minimum. Wherever practicable, the distance between such intersections shall not be less than 750 feet;
(3) Intersections on local streets shall be offset at least 250 feet measured from the centerlines of the two streets;
(4) Property lines at street intersections shall be rounded with a minimum radius of 20 feet or of a greater radius when required by the Plan Commission, or shall be terminated by a straight line through the points of tangency of an arc having a radius of 15 feet; and
(5) Local streets shall not necessarily continue across arterial or collector streets, but if the centerlines of such local 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 adjournment across the arterial or collector street is continuous and a jog is avoided.
(Prior Code, § 18.08)
(A) 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) In addition:
(1) The length of blocks in residential areas shall not, as a general rule, be less than 400 feet nor more than 1,200 feet in length unless otherwise dictated by exceptional topography or other limiting factors of good design;
(2) Pedestrian ways are generally not desired and should be avoided; however, pedestrian ways of not less than ten feet in width may be required near the center and entirely across any block over 900 feet in length where deemed essential by the Plan Commission to provide adequate pedestrian circulation or access to schools, parks, shopping centers, churches, or transportation facilities;
(3) The width of blocks shall be wide enough 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; and
(4) Utility easements. See § 153.073.
(Prior Code, § 18.08)
(A) 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.
(B) The lots should be designed to provide an aesthetically pleasing building site and a proper architectural setting for the building contemplated. In addition:
(1) Side lot lines shall be at approximately 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;
(2) Double frontage and reverse frontage lots shall be prohibited except where necessary to provide separation of residential development from through traffic or to overcome specific disadvantages of topography and orientation;
(3) Subject to the provision in § 155.026(B), every lot shall front or abut for a distance of at least 60 feet;
(4) Area and dimensions of lots shall conform to the requirements of Chapter 155;
(5) Depth of lots shall be a minimum of 100 feet, excessive depth in relation to width shall be avoided and a proportion of two to one shall be considered a desirable ratio under normal conditions. Depth 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;
(6) Width of lots shall conform to the requirements of Chapter 155;
(7) Corner lots shall have an extra width of ten feet to permit adequate building setbacks from side streets; and
(8) Lands lying between the meander line and the water’s edge and any otherwise unplatted 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 lake or stream.
(Prior Code, § 18.08) (Ord. 2-02, passed 1-24-2002)
(A) Electric and communication facilities.
(1) Adequate easements shall be provided and dedicated on each side of all rear lot lines and on side lot lines, across lots or along front lot lines where necessary, for the installation of electric and communications facilities. Such easements shall be noted as “utility easements” on the final plat or certified survey map. Prior to approval of the final plat or certified survey map, the concurrence of the electric and communications companies serving the area as to the location and width of the utility easements shall be noted on the final plat or certified survey map.
(2) Where the electric and communications facilities are to be installed underground, the utility easements shall be graded to within six inches of final grade by the subdivider, prior to the installation of such facilities, and earth fill, piles or mounds of dirt, or construction materials shall not be stored on such easement areas.
(3) Where the electric and/or communications facilities are to be installed underground, a note shall be placed on the final plat or certified survey map sating that the final grade established by the subdivider on the utility easements shall not be altered by more than six inches by the subdivider or his or her agent, or by subsequent owners of the lots on which such utility easements are located, except with written consent of the utility or utilities involved.
(B) Gas facilities. Distribution gas mains and appurtenances, except service laterals, shall be installed in the street right-of-way, normally in the area between sidewalk and curb. However, the Plan Commission may, at the request of the utility, or where deemed necessary or desirable, require easements of adequate width for the intended purpose along lot lines or across lots for such installations, and such easements shall be noted on the final plat or certified survey map as “utility easements”.
(C) Drainage easements. Where a subdivision is traversed by a watercourse, drainageway channel, or stream, an adequate drainageway or easement shall be required subject to the approval of the Zoning Administrator; 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. These design details are subject to review and approval by the Village Engineer.
