Unit 5 Learning Check NFIP Flashcards
what publications has the NFIP requirements for communities
Chapter 4 of the code of federal regulations (CFR)
most of the requirements relative to your communities ordinance are in 44 CFR parts ___ and ___
59
60
which part of 44 CFR 60.3 covers the requirements for areas with a FIRM, but no base flood eelvations
44 CFR 60.3 (b)
what is basic rule #1 for using maps and data
use the latest maps and flood data published by FEMA
what is basic rule #2
a permit is required for all development in the SFHA shown on FIRM
what is basic rule #3
development must not increase the flood hazard on other properties
what is basic rule #4
new, substantially improved or substantially damaged buildings must be protected from damage by the base flood
what map do you use if recently annexed areas do not show up on your community FIRM
the FIRM for the county or community the property used to be in
the community generally must also adapt the map in its ordinance to be legally enforceable
if you find information that shows the ground to be higher than the BFE, can a bank use that data when determining whether a flood insurance policy must be purchased
no. insurance agents and lenders must use current FIRm when setting rates and determining if flood insurance is required
if a person wants to vary from the current FIRM to obtain different premium rates or to not have to purchase a flood insurance policy, the FIRM must be officially revised or amended by LOMA
site E is in the approximate A zone of Dean Lake. A developer wants to build a small commercial building on a 3 acre site. where do you get base flood elevation for site E
check with State NFIP coordinator, local water districts, corps of engineer for existing studies
a highway agent might have done a study of the stream when turnpike bridge was built
see if the town engineer or the developers engineer with conduct a study
use the flood of record + margin of protection
a developer downstr4eam of Dean lake wants to build a 40 acre subdivision that crosses Ireland creek. you need a base flood elevation before you review the plans. what option do you tell the developer he has?
he can conduct a flood study and produce the BFE at his expense
he can set the A zone aside as open space and not conduit a flood study
a restudy was preformed on the Josias river. the preliminary study will not be final for above 5 months. it shows a new BFE at site N that is 2 feet higher than the BFE in your current FIS. which one do you use to determine if the flood protection level for a new home at site N
the draft revised data should be used
unless community disagrees with data and intends to appeal. the community must first legally adapt the preliminary study in their ordinance
define development in terms of ordinance
development is any man made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading , paving, excavation, or drilling operations or storage of equipment or materials
does your community only require building permits? if so, does someone who wants to fill a vacant lot need a permit from the community
yes
if not, revise the ordinance to be yes
the state in which flood county is situated requires a permit from the state department of Environmental Protection for development on primary sand dunes. a permit applicant wants to build on one near site F. Department staff informs you that based on the plans they have seen, they will have to deny the state permit. should the flood county permit officer issue a flood plain development permit
no
the local permit should not be issued until staff are certain the other agencies requirements are met.
if it is a question of time and a state permit is expected to be issued, a local permit could be issued conditioned on obtaining a state permit
if it is clear the project violates state regulation, a local permit should not be issued until the matter is settled
an encroachment review should review projects in a floodway for what 2 things
determine whether the project will obstruct flood flows and cause an increase in flood heights upstream or adjacent to the project site
determine whether the project will result in an increase in down stream flooding by removing an existing obstruction. this is not required by NFIP - but the changes can cumulatively cause large increases in downstream flooding
a farmer wants to build a dairy barn in the floodway. will be heed to provide you with a no rise certification before you can issue a permit
yes
the same farmer wants to build a small addition onto his farmhouse (within the floodway). can this be designed so he wont have to pay for an engineers encroachment review
yes - if it is located in the conveyance shadow of the farmhouse
in a riverine AE zone with a base flood elevation, what must a developer show in order to demonstrate that he is meeting basic rule #3
conduct an encroachment review that demonstrates that the cumulative effect of the proposed development, when combined with all other existing and anticipated development:
will not increase water surface elevation of base flood more than 1 ft in any point within the community
is consistent with the technical criteria contained in CH 5 of the flood insurance study. FEMA-37, 1995
does your state have more restrictive standards than allowing flood heights to increase by 1 ft
depends on state - some have 0.5ft or even 0.1ft max
where would elevation in piles or columns be preferred
areas where flooding is likely to have high velocities or waves
can the basement be considered the lowest floor
yes
if a residence is elevated above the BFE in A zone, where do you measure how high the building is
at top of lowest floor
what can be allowed under the lowest floor of an elevated building
only building access, vehicle parking, storage
