The purpose of this article is to encourage flexibility in the
design and development of land in order to preserve valuable open
space, scenic qualities, environmentally sensitive features and sites
of historical significance, and to facilitate the economical construction
and maintenance of roads and other improvements.
In its approval of site plans for a conservation subdivision,
the Planning Board shall maintain accurate records and maps showing
the location of permanent open spaces. No further development upon
the designated open spaces shall be permitted.
