The FIRM and the FIS report are incorporated herein by reference and are on file with the Town Clerk and Building Inspector.
The following requirements apply in Special Flood Hazard Area Districts:

(1)

The base flood is the flood having a one-percent chance of being equaled or exceeded in any given one year.
(2) 
Any encroachment meeting the above standard shall comply with the floodplain (special flood hazard area) standards of the State Building Code as well as the performance standards in 310 CMR (Wetlands Protection Regulations).
