Primary intended use. The Open Space District is designed
to restrict development on parcels of land essentially unimproved
and set aside, dedicated or designated or reserved for recreation
use or enjoyment. Consistent with that objective only the following
structures and uses shall be permitted:
Park and outdoor recreation uses of the type
which involve essentially unimproved land and only those structures,
off-street parking and other improvements that are designed to be
incidental to the natural openness of the land.
Accessory uses customarily associated with the
above uses, provided that such accessory uses are incidental to the
primary use, do not change the character of the primary use and serve
only the primary use.
