MAR. <br />17198Z <br />Mr. Jack Hauptman <br />Mr. Albert Green <br />February 24, 1982 <br />Page Two <br />BOOK 49R,. 1 <br />,E1 70 <br />The Draft Information Summary in its definition of un- <br />developed coastal barriers sets forth three requirements, all <br />of which must be met, for a coastal barrier to be classified <br />as undeveloped. The portion of John's Island categorized on <br />the present coastal barrier map as undeveloped does not meet <br />two of the three requirements necessary for an area to be <br />categorized as undeveloped. <br />(1) The first requirement is that within all or part <br />of an undeveloped coastal barrier, few man-made <br />structures may be present. <br />(a) In connection with the structures require- <br />ment, a density threshold of one structure <br />per five acres of fastland is used for <br />categorizing a coastal barrier as developed. <br />;If the density of structures is greater than <br />one unit per five acres, the fastland-is <br />developed. If the density is less than one <br />unit per five acres, the fastla4d is undeveloped. <br />A compg3�gon o,f the present coastal barrier <br />map with an -aerial photograph prepared in <br />January 1981, by the Florida Department of <br />Transportation for the Florida Department of <br />Revenue, indicates that approximately 264.85 <br />acres of fastland in the northern portion <br />of John's Island have been categorized as <br />undeveloped on the coastal barrier map. The <br />aerial photograph, which has had plat map <br />overlays added and is marked to show precisely <br />the area which we seek to classify as developed, <br />will be submitted to you at the February 24, <br />1982, meeting in Fort Pierce, Florida, on the - <br />undeveloped coastal barrier map. , <br />The photograph indicates that there are 107 <br />structures, as defined in the Draft Informa- <br />tion Summary, on that portion of John's Island <br />classified as undeveloped. Since the aerial <br />photograph was taken in January 1981, 1.0 nc-i <br />structures have -been added to that portion <br />of John's Island for a total of 117 structures. <br />Using these figures for calculation, there <br />2.21 units per 5 acres of fastland. There- <br />fore, under the Draft Information Surnmary <br />ret1tii.rements, that portion of John's Island <br />should be categorized as developed. <br />T <br />
