Facility Flood Hazard Assessment & Mitigation

For More Information, Contact:  Dan Stapleton, P.E. [email protected]   

Comple ng a successful review and

appeal of FEMA maps requires a detailed

understanding of FEMA guidelines and

methodologies.  GZA is well‐versed in

FEMA’s guidelines for the evalua on of

flood impacts and the delinea on of

flood zones. GZA has been assis ng

private property owners, businesses and

communi es with the iden fica on,

confirma on and evalua on of flood

map modifica ons.     

The  Federal  Emergency  Management  Agency  (FEMA), 

through  the Map Moderniza on program,  is responding 

to  Na onal  Flood  Insurance  Program  (NFIP) 

requirements  for  upda ng  the  Flood  Insurance  Rate 

Maps  (FIRMS) and  is u lizing  improved  technologies  for 

iden fying flood hazards.    In many areas,  the new data 

and methodologies have significantly  increased the Base 

Flood Eleva ons (BFEs) associated with areas that have a 

1 percent or greater chance of flooding in any given year. 

These  100‐year floodplains  and flood  zone delinea ons 

are allowed a 90 day appeal process as  the Preliminary 

FIRMs.   

  

As  these  Preliminary  FIRMs  become  adopted  into  law, 

the  map  modifica ons  can  have  significant  economic 

implica ons for both private and public property owners 

deemed by FEMA to be exposed to flood risk. Residents 

and businesses with  federally‐backed mortgages will be 

required to purchase flood insurance. Premiums for flood 

insurance  are  increasing  significantly  due  to  reforms  in 

the Biggert‐Waters Flood  Insurance Reform Act of 2012 

and  the  Homeowner  Flood  Insurance  Affordability  Act 

(H.R.  3370)  of  2014, which will  phase  in  actuarial  risk‐

based  rates  for  na onal  flood  insurance  policies  over 

several  years  and  promote  affordability measures  that 

are not yet defined.
