This is an area to be <br />protected from the 100-year flood by a <br />Federal flood protection system under <br />construction. It is shown by FIS spnbol <br />AI04. <br /> <br />This code identifies an area <br />but possible flood hazards. <br />FrS symbol AllO. <br /> <br />of undetermined <br />It is shown by <br /> <br />This code identifies an area inundated by <br />500-year flooding; an area inundated by 100- <br />year flooding with average depths of less <br />than 1 foot or with drainage areas less than <br />1 square mile; or an area protected by levees <br />from 100-year flooding. It is shown by FIS <br />symbol A108. . <br /> <br />This code identifies an area that is <br />determined to be outside the 100- and 500- <br />year floodplains. It is shown by FIS spnbol <br />AI09. <br /> <br />This code identifies a designated 1983 <br />Undeveloped Coastal Barrier Area in which <br />flood insurance is unavailable for structures <br />newly built or substantially improved on or <br />after October 1, 1983. The landward <br />boundaries of the area are coded with <br />attribute code 440 0256. The seaward limits <br />have no definite outline shown, therefore, <br />the edge of the pattern is followed to <br />delimit the area (attribute code 440 0204). <br />It is shown by FIS spnbol Al13. <br /> <br />This code identifies a designated 1990 <br />Undeveloped Coastal Barrier Area in which <br />flood insurance is unavailable for structures <br />newly built or substantially improved on or <br />after November 16, 1990. The landward <br />boundaries of the area are coded with <br />attribute code 440 0257. The seaward limits <br />have no definite outline shown, therefore, <br />the edge of the pattern is followed to <br />delimit the area (attribute code 440 0204). <br />It is shown by FIS symbol Al14. <br /> <br />41 <br />
