in part: <br />Jeeves on Beach Erosion Control, Page 4 <br />ro <br />(Quote) "The eroding situation is apparently the effect <br />of several main natural and manmade causes resulting in a <br />general lessening of the .1ittoral drift along the coastline of <br />4 the county.....the breakdown of the protective foredune system <br />AUG 2 0 1975 <br />due to contruction by local interests of various shoreline <br />structures; and the deterioration of naturally occurring offshore <br />breakwaters." <br />Mr. Garland went on to say: "Probably the most important • <br />to the beach erosion problem in Vero Beach is a structure known <br />locally as'Riomar Reef' part of a larger reef system typical <br />of reefs in the area." (Close quote) <br />'We agree with Mr. Garland that probably the most effective <br />beach erosion control is found in reefs. That is what is needed. <br />And that is just what is formed by the jacks system. <br />The jacks, which are six -pronged and weigh over a ton each, <br />are self anchoring. As strong waves rush in and over the jacks, <br />the waves produce a forward and downward pressure thus forcing <br />the bottom three prongs of the jacks into the ocean bed. <br />Now consider this very important time factor: <br />This job of making and installing 4,000 steel reinforced <br />jacks can be accomplished, from start to finish, in from 4 to 6 <br />months, depending on two things: weather conditions and the <br />cooperation received from the sponsoring agency, namely, Indian <br />River County. <br />Forms for making the "jacks" are readily available and can be <br />trucked to Vero Beach in a matter of hours. The 241 cubic yards <br />• of conrete to make 4 -thousand "jacks" together with the 60 - <br />thousand lineal feet of #5 steel reinforcing rods are available <br />locally. The availability and the prices have 'been rechecked anti* <br />Bind 3 F*GE23 <br />
