The Commission wishes to limit hardened surfaces in Town of Marshfield
coastal areas that contain AO Zone and V Zone flood areas. The energy
in these flood zones is dissipated by soft, relatively flat surfaces.
Limiting the amount of hard impervious surface is necessary to preserve
the wetland values of flood control, prevention of storm damage, prevention
of pollution, and public safety. In light of this, a request for a
conservation permit must be filed with the Commission prior to the
installation or replacement of hardened surfaces including patios,
walkways, driveways or similar structures in FEMA flood map AO and
V Zones flood areas.
