The sketch plan shall be required to enable
the subdivider to save time and expense in reaching a general agreement
with the Planning Board as to form, layout and objectives of these
Subdivision Regulations.
Approval of the sketch plan shall expire six
months after the date of such formal action, unless a proper application
for a subdivision has been submitted to the Planning Board. No action
will be taken after such expiration until a new sketch plan has been
submitted or the plan is resubmitted.
