Development must not increase the flood hazard on other properties. - Answers-What is basic rule #3 for encroachments in riverine floodplains? The FIRM for the county or the community the property used to be in. - Answers-What map do you use if recently annexed areas do not show up on your communities FIRM? No. Insurance agents and lenders must use the current FIRM when setting insurance rates and determining whether 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. This can be done through LOMA. - Answers-If you find information that shows the ground to be higher that the BFE, can a bank use that data when determining whether a flood insurance policy must be purchased?
- Check with your state NFIP coordinator, local water-related districts, the COrps of Engineers, etc. to see if there are any existing studies.
- See if the Town Engineer or the developers engineer will conduct a study.
- Use the flood of record plus a margin of protection. - Answers-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.

- He can set the A zone aside as open space and not conduct a flood study. - Answers-A developer downstream 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 options do you tell the developer he has? The draft revised data should be used unless the community disagrees with the data and intends to appeal. As noted previously, the community must first legally adapt the preliminary study in their ordinance. - Answers-A restudy was performed on the Josias River. The preliminary study will not be final for another five months. It shows a new BFE at Site N that is two feet higher than the BFE in your current FIS. Which one do you use to determine the flood protection level for a new home at Site N? Any man-made change to improved or unimproved real estate, including but not limited buildings or other structures, mining, dredging, filling , grading, paving, excavation or drilling operations or storage of equipment or materials. - Answers-Define "Development" as the term is used in your ordinance. No. The local permit should not be issued until staff are certain that other agencies requirements are met. If it is just 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. However, if it is clear that the project violates the state regulations, a local permit should not be
issued until the matter is settled. - Answers-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 floodplain development permit? You must determine whether the project will result in increases in downstream flooding by removing an existing obstruction. While you are not required to do this by NFIP minimum requirements, these changes can cumulatively cause significant increases in downstream flooding. - Answers-An encroachment review should review projects in a floodway for what two things? Yes. - Answers-A farmer wants to build a dairy barn in the floodway. Will he need to provide you with a "no-rise" certification before you can issue the permit? Yes, if it is located in the conveyance shadow of the farmhouse. - Answers-A farmer wants to build a small addition onto his farmhouse (In the Floodway). Can this be designed so he wont have to pay for an engineer's encroachment review?

- 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. - Answers-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?

No. It can only be elevated on posts, pilings, piers or columns to avoid obstructions to the wave action. - Answers-Can a new building be built in the V Zone elevated on a crawl space? At the bottom of the lowest horizontal structural member. - Answers-Where is the lowest floor measured in a V Zone? Have an engineer certify that the design and planned methods of construction are in accordance with accepted standards of practice to resist flotation, collapse and lateral movement due to the effects of wind and water loads acting simultaneously on all building components. - Answers-What does the permit official do to be sure that a V Zone building will be adequate to resist the wind and water loads? Don't touch them. They provide important flood protection by breaking waves during coastal storms. If they are to be disturbed, the permit applicant should have an engineers or geologists report that their removal will not increase flood damage. - Answers-What's the best way to deal with sand dunes in a V Zone development site? The subdivider also needs to make sure that:
- All public utilities and faculties, such as sewer, gas, electrical, and water systems are located and constructed to minimize or eliminate flood damage
- Adequate drainage is provided to reduce exposure to flood hazards - Answers-If a subdivider makes sure that all building sites are above the BFE, does he need to do anything more to meet the NFIP requirements? Through careful system design. Manholes should be raised above the 100-year flood level or equipped with seals to prevent leakage. Pumping stations should have electrical panels elevated above the BFE. - Answers-How can you protect a sewer system from flooding? 44 CFR 59.1 Definitions - Answers-In what part of the code of federal regulations would you find the definition for development?

The requirements are cumulative in section 60.3 - Answers-If your community follows the requirements of 44 CFR 60.3(d), does it have to worry about what's in 44 CFR 60.3(b)? No. The community must use the latest maps and data provided by FEMA. If the other map shows a higher BFE and a larger floodplain, the community map adopt it in its ordinance as the regulatory floodplain and exceed the minimum NFIP requirements. The map must be approved by the FEMA Regional Office before this is done. - Answers-A building official finds it easier to read an old flood map prepared on an aerial photograph by the corps of engineers. He doesn't want to use the current FIRM because it doesn't show all the buildings and features that the photograph does. Can he make permit decisions based on the Corps map instead of the FIRM? The Community Rating System (CRS) - Answers-What NFIP program recognizes local regulatory standards that are more restrictive than the minimum NFIP regulations? taking - Answers-If a regulatory requirement prohibits an owner from any use of his land, it is referred to by the legal term _____? None. - Answers-In how many court cases have the NFIP regulations been overruled as unconstitutional? The more restrictive state requirement. - Answers-If a state requirement is more restrictive than an NFIP requirement, which set of rules must a community follow?
- Subdivision design that encourages cluster development on high ground
- Low density zoning that gives owners large lots large enough to avoid small floodplains - Answers-Name two higher regulatory standards than can be used to encourage building sites completely out of the floodplain.

During the second inspection, before the floor is built. This will allow the builder to install the needed openings with a minimum of disruption to the structure. - Answers-When is the best time to see if a crawl space has adequate openings? It authorizes FEMA to deny flood insurance to a property declared in violation of the community's ordinance.
