The location of farm roads should be used as driveway access to dwelling units or as street access into the development, where feasible.

(M)

Open Space:

1)

A minimum of fifty (50) percent of the gross land area, less open space credits and excluding existing street right-of-way shall be open space as defined below.

2)

In a RPD, qualifying open space shall be that land:

Open Space Credits: The Sidewalk/Trail Network area shall be calculated by multiplying linear feet by twenty (20) feet. Every acre or portion thereof provided in sidewalk/trail network shall be deducted from the total minimum fifty (50%) percent open space requirement. (e.g. A one hundred (100) acre site providing one (1) mile [2.42 acres] of trail would reduce the minimum open space requirement from fifty (50) acres to forty-seven and six-tenths (47.6 acres.)

3)

To qualify as open space, land shall be useable for sewage treatment, recreation purposes, provide visual, aesthetic, or environmental amenities, or be agriculturally productive land, and may not be occupied by street rights-of-way, drives, parking areas or structures, other than recreational structures and those associated with community well or sewage systems.

4)

Land within a floodway, floodway fringe zone, or bodies of water greater than one (1) acre in size may be used to provide not more than fifty (50%) percent of the open space required in development.

Open space containing planned improvements shall be provided within each phase of the planned unit development in sufficient amounts to serve the expected population of that phase or the gross land area devoted to nonresidential land uses.

6)

1)

Location and Purpose: The development shall provide a pedestrian/bikeway trail network linking:

The walkway maybe located within a public street right-of-way subject to the approval of the Jurisdiction maintaining the public street.

3)

Maintenance: Maintenance of the trail network shall be the responsibility of a Owners Association for all trails located outside public street right-of-way. Trails located within public street right-of-way may be maintained by the Jurisdiction maintaining the public street, subject to the Jurisdiction's approval.
