(A) Essential utilities and public services. Land proposed to be subdivided shall have essential utilities and public services available within a reasonable distance and time period. Land to which these essential utilities and services will not be so provided shall be deemed unsuitable for subdividing. Essential utilities and services and criteria for determining if they can adequately be provided shall include the following:
(1) Sewage disposal:
(a) Sanitary sewer service provided by the Springfield Metro Sanitary District shall be the preferred method of sewage disposal. If sanitary sewer service is currently available to the land proposed to be subdivided, it shall be the sewage disposal method used.
(b) If sanitary sewer service is not currently available but the land is within the ultimate service area as identified in the Springfield Metro Sanitary District's Facility Plan and the Sanitary District determines that sewer service will be available within a reasonable period, the land may be deemed suitable for subdividing if:
1. Sanitary sewers shall be installed by the subdivider for future service to each building site; and
2. On-site sewage disposal facilities can and will be provided.
(c) If the land cannot be served with sanitary trunk sewers within a reasonable period, or if the land is not within the ultimate service area as identified in the Springfield Sanitary District's Facility Plan and therefore shall be unsuitable for subdividing unless it can be shown that adequate private sewage systems can be provided.
(2) Water supply:
(a) An Illinois Environmental Protection Agency approved public water supply shall be the preferred method of water supply.
(b) Private wells may be permitted for developments outside the village if the developer can demonstrate that it is not feasible to extend water mains to the land proposed to be subdivided. As a minimum guideline, the extension of 120' +- of water main per lot of the preliminary plan shall be deemed feasible. This distance shall be measured between the nearest suitable public water main and the proposed development. Mains within the development shall not count toward this extension footage.
(3) Fire protection: Land proposed to be subdivided shall meet the following conditions in order to be deemed suitable for subdividing:
(a) Land shall be within a fire protection district, if possible;
(b) There shall be a public road providing adequate access for emergency vehicles to the site, in accordance with the criteria outlined in § 155.022(A)(4)(a) below.
(c) There shall be a system of water mains or other source of water adequate for fire fighting purposes. Specific fire flows shall be determined by the Chatham Fire Protection District using a standard published by the Insurance Service Office entitled “Guide for Determination of Required Fire Flow”.
(d) A full sprinkler system installed with adequate water available as determined by the National Fire Protection Association Standards 13 or 13D depending on the occupancy of the building shall also satisfy this requirement.
(a) The suitability of existing streets for access to the proposed subdivision and/or for incorporation into the proposed subdivision’s street system shall also be considered. A street shall be considered suitable if:
1. The street is constructed of all weather material (concrete, asphalt, oil mat);
2. For low volume residential development (less than 250 vehicles per day), the pavement has the strength to carry fire trucks (minimum two-inch asphalt on six-inch crushed rock or equivalent);
3. For higher volume residential developments (greater than 250 vehicles per day) and non-residential developments, a traffic impact study and pavement evaluation/design may be required to assess the suitability of adjacent existing streets to support the anticipated traffic volume and loading for the intended use. Pavements shall be designed for the 10 year traffic projections for the anticipated future development in the area. The paved area is at least 20 feet wide with a road bed 24 feet wide;
4. There is a minimum vertical clearance of 14 feet, six inches;
5. The street has adequate cross slope and roadside ditch or storm sewer capacity; and
6. Access roads and access road intersections that serve the development must meet safety standards, including sight distance.
(b) If only a portion of the criteria set forth in division (A)(4) is met, the village’s consulting engineer, a representative of the Chatham Fire Protection District, and a representative of the Planning Commission shall make the recommendation as to whether the street is suitable for the proposed development or what improvements must be undertaken to make it suitable.
(5) Police protection: In determining the suitability of land for subdivision purposes, the distance that police would have to travel to respond to a call for service shall be considered.
(B) Other requirements. Land proposed to be subdivided shall meet the following requirements:
(1) Site must be in conformance with the Chatham Comprehensive Plan;
(2) Development must not be located in a 100 year floodplain or flood prone area.
(3) Development must not be located in any environmentally sensitive area including sites adjacent to Lake Springfield and its tributaries unless the subdivider can show that environmental concerns can be mitigated.
(4) Site must be of a shape, size and terrain so that usable lots and streets in conformance with this chapter can and will be created.
(5) Development must not have a major conflict with existing use of adjacent property (waste water treatment plants, power plants, major industrial plants, landfills, certain agricultural uses, etc.) unless it is shown that factors which cause the conflict can and will be mitigated.
(6) Development must not cause major off-site impacts and problems relating to, but not limited to, streets, drainage, water supply and distribution system, sanitary sewer collection system, parks. If it is determined by the Planning Commission that major off-site impacts will result, the subdivider must agree to mitigate the portion of the impact caused by the subdivision. A traffic impact study, water network model, and/or a hydraulic loading analysis of the sanitary collection system may be required to evaluate the degree of off-site impacts, and to evaluate improvements that may be required to mitigate impacts.
(7) When soils in the area to be developed have severe limitations for building site development or sanitary facilities as determined by the USDA Soil Conservation Service, the subdivider shall submit information indicating how these limitations will be addressed.
