(A) Generally.
(1) The land dedication required herein shall be six acres per 1,000 new residents, derived from the following calculation:
Types of Park/Recreation Area | Minimum Size of Park (Range) | Minimum Acres Per 1000 People | Service Area Radius | Maximum Street/Trail Distance from Any Proposed Dwelling |
Mini-Park | 1 acre | 0.5 | 0.25 mile radius | 1,000 feet |
Neighborhood Park | 3.0 - 10.0 acres | 1.5 | 0.5 mile radius | 2,500 feet |
Community-Wide Recreation Park | 30 - 50 acres | 4.0 | 3.0 mile radius | Within jurisdictional area |
TOTAL: 6 acres of land per 1,000 people | ||||
(2) Dedicated land shall not be limited to the specific formulas described above, but the dedications shall comply with the additional size, location, design and other requirements in this subchapter.
(B) Density formula. The following table of population density is generally indicative of current and short-range projected trends in family size for new construction and shall be used in calculating the amount of required dedication of acres of land or the cash contributions in lieu thereof attributable to each development:
Density Formula for Estimated Ultimate Population per Dwelling Unit | |
Type of Unit | Total Persons Per Unit |
Detached single-family | 2.83 |
Attached sf/duplexes | 1.97 |
Apartments/condominiums* | 1.66 |
Mobile homes | 2.43 |
NOTES TO TABLE: *Calculations are based on information provided for O’Fallon City, IL by the U.S. Census Bureau, Census 2000 (www.census.gov). Data was taken from table H33. TOTAL POPULATION IN OCCUPIED HOUSING UNITS BY TENURE BY UNITS IN STRUCTURE and divided by H32. TENURE BY UNITS IN STRUCTURE. Ex. Detached single-family data give 16,514 residents (H33) living in 4,962 detached units (H32). 16,514 people/4,692 units = 2.83. |
