Requirement And Population Ratio: The number of students to be generated by a subdivision shall bear directly upon the amount of land required to be dedicated for school sites. This land dedication requirement shall be determined by obtaining the ratio of: 21 1. The estimated number of children to be generated in each school classification by the subdivision over 2 The maximum recommended number of students to be served in each school classification as stated herein, and then applying that ratio to 3) 3. The minimum recommended number of acres for a school site for each school classification as stated herein. The product thereof shall be the number of acres of land deemed needed for school site purposes to serve the needs of the children in each school classification generated by the subdivision. B. School Classifications And Size Of School Site: For purposes of this Title, school classifications and the size of school sites within the Village shall be determined in accordance with the following criteria: Minimum Number Maximum Number Of Acres Of School Of Students For Land For Each Classification Each Such School School Site Of By Grades Classification Such Classification Elementary Schools, Grades Kindergarten through 5 600 11 Junior High Schools, Grades 6 through 8 900 19 High Schools, Grades 9 through 12 2,300 48 C. Location Sites: The standards adopted by the affected school district shall be used as a guideline in locating sites. D. Criteria For Requiring Cash Contribution In Lieu Of Land Dedication: When a subdivision is small and the resulting acreage too small to be practical, or when the available land is inappropriate for school site purposes, or when the owner or subdivider shall otherwise agree with an involved school district or other such public body with jurisdiction, the Village shall require or permit the owner or subdivider to make a cash contribution in lieu of the required land dedication under this Title. Such cash contributions shall be paid to the appropriate school district or other public body having jurisdiction over schools in the area in which the particular subdivision is located, to be held in trust by such school district or public body solely for use in the acquisition of land 22 for facilities, or the construction of new facilities, or the addition to existing facilities, to serve the immediate or future school needs of the residents of the subdivision, or for the improvement of any existing school site that already serves such needs, except that when an owner or subdivider shall otherwise reach agreement with an involved district as hereinbefore referred to, then any cash contributions shall be paid and used as provided in said agreement.

Thereupon, the Village shall make a determination, which shall be final, of such value.

F. Criteria For Requiring Both Dedication Of Land And Cash Contribution: It is recognized that there are occasions in the development of subdivisions when a combination of land dedication and, partly in lieu thereof, a cash contribution both, shall be necessary and advisable. These occasions include: 1. When only a portion of the land to be subdivided is proposed as the location of a school site, that portion of the land within the subdivision situated in the proposed location shall be dedicated in the manner herein provided, and a cash contribution in lieu thereof shall be required for any additional land that would have been required to be dedicated in accord with the provisions of this Title; or 2. When a major portion of the school site has already been acquired and only a small portion of land is needed to complete the site, such remaining portion shall be required by dedication, and a cash contribution in lieu thereof for the balance shall also be required. G. Student Generation: 2 3 1. The number of students generated by a residential unit in a subdivision shall be periodically determined by the Village.

The owner or subdivider may file a written objection to the determinations of the Village made in the manner described above in which event the owner or subdivider of the subdivision shall submit his own demographic study showing the student population to be generated by the subdivision. Thereupon, the Village shall make a determination of the same, which determination shall be final. 3. It is to be recognized that population densities, student generation figures, acre distribution and local conditions change over the years and the specific formula for the dedication of land, or in lieu thereof a cash contribution, as herein provided, is subject to periodic review, as herein contemplated or otherwise, and amendment as necessary. 4. The number of elementary school children (kindergarten through grade 5) per residential unit to be utilized shall be 0.35; the number of junior high school children (grades 6 through 8) per residential unit to be utilized for the same period shall be 0.30; and the number of secondary school children (grades 9 through 12) per residential unit to be utilized for the same period shall be 0.30.
