What is Basic Rule #3? - Answer Development must not increase the flood hazard on other properties 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? - Answer He must 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 the water surface elevation of the base flood more than one foot at any point within the community, and · Is consistent with the technical criteria contained in Chapter 5 (Hydraulic Analyses) of the Flood Insurance Study: Guidelines and Specifications for Study Contractors, FEMA-37, 1995. What does Basic rule #4 say about new buildings in A Zones? - Answer New, substantially improved or substantially damaged buildings must be protected from damage by the base flood.

Development alters the floodplain and the dynamics of flooding 2. Buildings and infrastructure are damaged by periodic flooding. What does watershed development do to flooding? - Answer The increase in impervious surface results in increased runoff and higher flood levels. What is one of the problems with constructing seawalls to protect buildings from flooding or erosion? - Answer It can accelerate erosion on properties at the end of the wall. What are the five main causes of flood damage? - Answer 1. Hydrodynamic forces 2. Debris impact 3. Hydrostatic forces 4. Soaking 5. Sediments and contaminants Standing water as little as _____ feet deep can collapse the walls of a frame house. - Answer 3 feet What are some of the safety and health hazards that accompany floods? - Answer 1.

Mold, mildew, and bacteria that grow in damp, flooded areas 7. Contaminated air from dirty heating ducts 8. Stress and mental health problems Prior to the 1960s what was the primary way to reduce flood losses? - Answer Structural flood control projects What is the Unified National Program for Floodplain Management's definition of "floodplain management"? - Answer "A decision-making process that aims to achieve the wise use of the nation's floodplains" What are the two primary goals of floodplain management? - Answer 1. To reduce the loss of life, disruption, and damage caused by floods 2. To preserve and restore the natural resources and functions of floodplains What areas are conductive to flash flooding? - Answer 1. Hilly area with steep slopes and narrow valleys 2. Urban areas with large amounts of impervious surfaces and storm sewers 3. Area downstream of dams or subject to ice jams Is erosion only a threat in coastal areas? - Answer No. Riverine erosion can move stream channels and undercut structures. What is ponding? - Answer Where stormwater runoff collects in depressions and cannot drain out. Are plants and animals the only beneficiaries of the "natural and beneficial functions" of floodplains? - Answer No. People benefit from floodplains through the food they provide, the recreational opportunities they afford, and the scientific knowledge gained in studying them. Floodplains also recharge groundwater supplies and their filtering actions help improve water quality. What does filling in a floodplain do? - Answer Filling reduces the floodplain's ability to store excess water, sending more water downstream and causing floods to rise to higher levels. Does moving sand and sand dunes affect flooding? - Answer Yes, it may remove a natural barrier that protects inland properties. 1.

Wood 2. Gypsum wallboard 3. Furniture and upholstery 4. Carpeting 5. Mattresses 6. Books 7. Electrical appliances 8. Gasoline engines
