Unit 6 Learning Check NFIP Flashcards
Wha NFIP program recognizes local regulatory standards that are more restrictive than the minimum NFIP regulations
the community rating system (CRS)
if a regulatory requirement prohibits an owner from any use of his land, it is referred to by the legal term
taking
how many court cases has the NFIP regulations been overruled as unconstitutional
0
if a state requirement is more restrictive than the NFIP requirements, which set of rules must a community follow
more restrictive - state requirement
name 2 higher regulatory standards that can be used to encourage building site completely out of the floodplain
subdivision design that encourages cluster development on high ground
low density zoning that gives owners large lots large enough to avoid small floodplains
what is freeboard
additional height requirement above BFE that provides a margin of safety against extraordinary or unknown risks
what is the preferred flood protection approach for critical facilities
keep them out of the 500 year floodplain.
next best, is to protect them to the 500 year flood level
how does compensatory storage work
the developer is required to offset new fill put in the floodplain by excavating additional floodable area to replace the lost flood storage area
what is stormwater management
efforts that reduce the impact of increased runoff that results from new development in the watershed
7 special flood hazards
coastal erosion
tsunamis
closed basin lakes
uncertain flow paths or alluvial fans
upstream dams
ice jams
mudflows
federal agencies regulate wetland development, protect rare species, etc. is there need for your community to consider additional environmental protection measures
yes, federal programs may not address particular needs or your locality
name 3 types of regulations that protect natural resources in floodplains
wetland protection
habitat protection
restriction on on site sewage disposal
water quality regulations and rules on stormwater runoff (non point source)
designing unique or valuable areas for special protection
does NFIP allow communities to enact more restrictive regulatory standards
yes
44 CFR 60.1(d) - regulations adopted by state or community which are more restrictive are encourage and take precedence
can a floodplain regulation ever prohibit new buildings from portion of the floodplain
yes
if areas is sufficiently dangerous or clear relationship between prohibition and protecting the public from the hazard created by the development
2 types of floodprone areas where many communities prohibit development
high hazard area - flash floor or deep floodways
natural or sensitive areas - wetlands
whats the advantage of requiring dry land access if buildings are protected from flooding
it protects people by allowing them to evacuate when floodwaters come up and allow emergency service vehicles to protect the properties during a flood
how could a developer of an 80 acre subdivision reduce the amount of runoff that leaves the property during a storm
include stormwater detention or retention basins to hold or delay runoff from the site
do federal agencies have to meet any floodplain development rules similar to the NFIP requirements
yes.
national environmental policy act (NEPA) and executive order 11988 requires federal agencies to meet the same or more restrictive development standards
