A. The slope, topography and geology of the dedicated site as well as its surroundings must be suitable for its intended purpose. Wetlands and floodplains may be accepted for Village ownership and maintenance but shall not serve as a credit toward the required park site dedication. Storm water detention areas shall not be accepted for Village ownership and maintenance, and the portion of a detention area designed to function primarily as a component of the storm water control system shall not serve as a credit toward the required park site dedication. A park site shall be not less than one acre in area. The Village Board reserves the right, however, in its sole discretion, to accept in whole or in part, certain areas such as, but not limited to, tree massings, prairie remnants, high quality or unique wetlands, or other natural features as all or part of the required park site dedication in furtherance of open space preservation that may be unique to a given parcel or development. Wetlands, floodplains, detention areas, retention areas and areas of steep slope shall not be accepted as school, park, fire/rescue or library sites and shall not serve as a credit toward the required school, park, fire/rescue or library site cash contribution in lieu of land dedication.
B. In addition, the following site conditions and preparation standards shall be met:
1. Slope:
a. Should not vary greatly in appearance from existing and adjacent slopes;
b. Optimum slopes range from two percent (2%) minimum to five percent (5%) maximum. No less than two percent (2%) slope is acceptable under any circumstances;
c. Maximum allowable slope is ten percent (10%), except under special conditions where greater slopes are desirable to enhance the use of the site; and
d. On site drainage patterns shall be designated and constructed to:
(1) Ensure flow toward swales; and
(2) Ensure drainage away from active areas.
2. Grading:
a. Rough grading shall be completed at time of rough grading of adjacent contiguous area;
b. Grading shall comply with Village approved plans;
c. Subgrade shall be graded and compacted so it will parallel finished grade;
d. Subgrade material shall be loosened and fine graded to a depth of two (2) to four inches (4"). All stones over four inches (4") in size, sticks, debris, rubbish and other foreign substances shall be removed; and
e. Finished grades shall be uniform in slope between points for which elevations have been established.
3. Soils:
a. Soils shall not differ from those naturally occurring;
b. Soils shall not offer any restriction to the ultimate use of the property;
c. Topsoil shall be spread evenly and lightly compacted to a minimum depth of six inches (6") over the entire site;
d. Topsoil must be good, friable soils with good tillage and shall be without any admixture of subsoil, clay, gravel, stones, debris, refuse, sand or other subsurface elements;
e. Topsoil shall not be placed in a muddy or frozen condition;
f. Topsoil shall contain no toxic substances which may be harmful to plant growth; and
g. Topsoil shall be spread no later than the placement of topsoil on the first lot adjacent to the site.
4. Seeding:
a. All proposed library, park and recreational and school sites shall be seeded and an acceptable stand of grass or vegetation established prior to dedication of the area to the Village;
b. Village approved ground covers and grasses shall be used for all park and recreational areas suitable for the nature of the activity planned to occur thereon;
c. Seeding shall be completed during the fall or spring planting times, depending upon the recommended seed planting specifications;
d. Seeding shall be on moderately dry soil on a seed bed which will easily accept and nurture germination of seeds;
e. Seeding shall be watered sufficiently so that the vegetation becomes reasonably established; and
f. The developer shall be responsible for making necessary reparations to the site caused by erosion or other damage. Reparations shall be completed prior to acceptance of the site. (Ord. 915, 2-13-2003)
