(A) Lot size. The lot size, width, depth, shape and orientations shall be appropriate for the location of the subdivision and for the type of development use contemplated.
(2007 Code, § 34-6-21)
(B) Conformity with zoning. Lot dimensions and areas shall as a minimum conform to the requirements of Ch. 155 of this code of ordinances. However, residential lots not served by public sanitary sewers and water supply shall be not less than 100 feet wide at the building line and not less than 20,000 square feet in area. Where either community sanitary sewers and sewage treatment or water supply is provided, a lot shall be not less than 80 feet wide and not less than 11,200 square feet in area.
(2007 Code, § 34-6-22)
(C) Lots abutting water. Lots abutting a watercourse, drainage way, channel or stream shall have a minimum width or depth as required to provide an adequate building site and to afford the minimum usable area required in this chapter or Ch. 155 of this code of ordinances for front, side and rear yards.
(2007 Code, § 34-6-24)
(D) Corner lots. All corner lots shall have a minimum width of 80 feet and be substantially larger than a normal lot to allow minimum building setback lines on both streets.
(2007 Code, § 34-6-25)
(E) Abutting a street. All lots shall abut on a publicly dedicated street.
(2007 Code, § 34-6-26)
(F) Double frontage. Double frontage and reverse frontage lots shall be avoided, except where essential to provide separation of residential development from highways or primary thoroughfares or to overcome specific disadvantages of topography and orientation. A planting screen easement of at least ten feet, and across which there shall be no right of vehicular access, shall be provided along the rear lot lines of lots abutting such highways and major thoroughfares.
(2007 Code, § 34-6-27)
(G) Lots at right angles. Side lot lines shall be substantially at right angles or radial to street lines.
(2007 Code, § 34-6-28)
Building setback lines in residential areas of new subdivisions shall conform to the front yard provisions of Ch. 155 of this code of ordinances; except that, in no case shall the building setback line be less than 25 feet from the front property line. The Plan Commission may require greater setbacks where the Plan Commission deems it necessary.
(2007 Code, § 34-6-30)
(A) Land may be required. Whenever the reasonable requirement provided by the comprehensive plan indicates the necessity for providing for a school site, park site or other public lands within any proposed subdivision for which approval has been requested, and no such provision has been made therefor, the governing authorities may require that land be designated for such public purpose before approving such plat. Whenever a final plat of subdivision, or part thereof, has been approved by the governing authorities as complying with the comprehensive plan and there is designated therein a school site, park site or other public land, the governing authorities having jurisdiction of such use, be it a school board, park board or other authority shall acquire the land so designated by purchase or commence proceedings to acquire such land by condemnation within one year from the date of approval of such plat; and, if it does not do so within such period of one year, the land so designated may then be used by the owners thereof in any other manner consistent with this chapter, including the comprehensive plan and Ch. 155 of this code of ordinances.
(2007 Code, § 34-6-31)
(B) Preservation of natural features. In subdividing any land within the village or within one and one-half miles of the corporate limits, due regard shall be shown for all natural features, such as, tree growth, watercourses, historic spots or similar conditions which, if preserved, will add attractiveness and value to the proposed development.
(2007 Code, § 34-6-32)
(A) All major drainage ways shall be designed as shown on the community storm drainage plan.
(B) Where no drainage plan exists, drainage ways shall be designed as follows.
(1) MAJOR WATERWAYS are defined as those with a tributary area in excess of four square miles. Such major waterways shall be designed for an average flood recurrence interval of 100 years.
(2) SECONDARY WATERWAYS are defined as those with a tributary area of between one and four square miles. Such secondary waterways shall be designed for an average flood recurrence interval of 25 years.
(3) (a) MINOR WATERWAYS are defined as those with one square mile or less of tributary area. Such minor waterways shall be designed for an average flood recurrence interval of ten years.
(b) Design flows for secondary and minor drainage facilities shall be computed by the subdivided engineer by use of the Rational formula:
Q = CIA in the urban areas
Wherein: Q = cubic feet per second
C = run-off coefficient
I = intensity of rainfall, inches per hour
A = tributary area
(c) Drainage structures and their easements shall be adequate to handle the flow from this formula.
(4) Drainage designs shall be accomplished for the subdivider by a professional engineer, registered in the state. The drainage plan and design shall bear the seal of professional engineer. The drainage plan will be subject to review and the approval of the Village Engineer.
(5) Flows for the design of secondary and minor drainage facilities within urban and suburban areas shall be calculated in accordance with the state’s Department of Transportation Storm Water Design Manual, latest revision.
(6) In the agricultural areas within the review area of the village, but outside the urban area, runoff calculations shall be made using the most appropriate method according to the current state of art of hydrology and current engineering practice (i.e., Cook’s or Soil Conservation Service methods).
(2007 Code, § 34-6-34)
STREET SYSTEM DESIGN
(A) In any new subdivision, the street layout shall conform to the arrangement width and location of streets as indicated on the village official map, comprehensive plan or the neighborhood development plan which was drawn up as part of the pre-application review.
(B) The overall plan in addition should conform to the following standards.
(1) In general, not more than 20% of the total land area of the subdivision should be in street right-of-way.
(2) The resulting street pattern should be properly related to topography and other natural features for aesthetic and drainage reasons. Further, the system should be so designed as to allow economic platting of the best building sites possible.
(3) The overall plan should result in proper functional classification of streets, with spacing of collector and major streets in accordance with standards contained in this section.
(4) The street system should afford satisfactory access to a public street to all building lots within the subdivision and provide the advantageous street service up to all adjoining lands.
(2007 Code, § 34-6-5)
(A) Street alignment shall be so laid out so as to ensure public safety and convenience for both vehicular and pedestrian travel.
(B) The following standard shall be followed in the alignment of streets.
(1) The number of intersections shall be kept to the absolute minimum necessary to provide reasonable direct traffic flow. No more than two streets shall converge at any one intersection. The intersection of streets shall be as near 90% as possible, never less than 70%.
(2) Street jogs shall be discouraged and should never be permitted with centerline offset of less than 150 feet.
(3) Reverse curves of major and collector streets shall not have tangents of less than 100 feet.
(4) The number of access points shall be reduced as the functional classification of the street increases and as travel volume and speed increases.
(2007 Code, § 34-6-6)
