� � r <br />and as a result we have some areas west of 43rd Avenue that are <br />in the 100 year floodplain. Director Davis noted that those <br />areas need to be developed with that in mind. We just had a new <br />small single family subdivision come in for approval in that <br />area, and we granted a waiver for the cut and fill balance until <br />this ordinance was adopted. He felt we are going to have to work <br />with the new ordinance to see what kind of design will be <br />compatible with the 100 year floodplain and also be sure that the <br />Comprehensive Land Use Plan does not drive densities too far up <br />in those areas to preclude the setting aside of retention areas <br />and providing ways to mitigate the 100 year storm. <br />Discussion continued regarding the regulations, and Attorney <br />Collins clarified that the area of the floodway that would be <br />under water during the 100 year storm could not be filled in. <br />Commissioner Bird noted that our whole county is based on <br />the canal system and drainage ditches. <br />Director Davis advised that he will be meeting with Indian <br />River Farms Water Control District later this month, and he <br />believedit will be a very enlightening meeting. There are many <br />questions regarding their manipulated flood control structures <br />and how you evaluate them regarding the system, i.e., whether you <br />assume them to be in an up or down position when the storm hits. <br />In any event, the only areas that are significant are west of <br />43rd Avenue. Now that the two studies are complete, however, he <br />was not sure that we should continue to grant waivers for fill in <br />the floodplain along the Indian River. For instance, in the <br />Garden Grove development there are certain sections along the <br />bank of the river that are below elevation 5, and as you fill <br />below that elevation, you are consuming some of the areas where <br />the water would be stored in case of an 100 year flood. Director <br />Davis referred to the wording on page 9 of the ordinance - <br />"Encroachments, including fill, new construction, substantial <br />improvements, and other development within the adopted regulatory <br />floodway that would result in any increase in flood levels within <br />29 ROG� 16 F1GE 75— <br />
