(c) Density computations shall be as follows:
(1) The total number of dwelling units permitted within an OSN shall be determined by multiplying the net acreage of the site by the density permitted within the zoning district in which the OSN is located. In determining net acreage, the following shall be deducted from the total size of the parcel:
A. One-half of those areas within the 100-year flood plain.
B. One-half of wetland areas or those areas permanently inundated by water, including lakes, ponds, streams, and rivers
C. One-half of those areas with existing slopes of twenty percent or more.
(2) Maximum densities for OSN developments are as follows:
A. R-1 District - a maximum of 5.44 units per acre
B. R-2 District - a maximum of 3.63 units per acre
C. R-3 District - a maximum of 2.64 units per acre.
(3) Additional dwelling units above what is permitted by paragraphs (c)(1) and (2) hereof may be permitted within the OSN at the discretion of the Planning Commission and the City Council if the development provides additional amenities or dedicates additional open space which would result in a significant recognizable benefit to the City or the residents of the OSN. Items which could be added to the OSN to allow it to be eligible for additional dwellings include:
A. Playgrounds with play equipment, ballfields, golf course, bike path, walking path, created lakes, community buildings or similar facilities.
B. Additional landscaping, walkways, benches, or similar items within a village square area.
C. Trails through natural areas such as wetlands, woodlands, and meadows.

(d) Lot size standards shall be as follows:
(1) Lots within an OSN shall be permitted to be smaller in area and width and have lesser setbacks than the minimum requirements of the zoning district in which the OSN is to be located in order to achieve the objectives of this chapter. Specifically, the lot size in the R-1 Zone shall be permitted a ten percent reduction, and the lot sizes in the R-2 and R-3 Zones shall be permitted a twenty-five percent reduction.
