The Leon ordinance contains a <br />design standard that prevents fill in the 100 year floodplain without <br />compensating volume. This may prevent flooding off-site, but it can <br />result in environmQntal nroblamcz including water quality deteriora <br />n• unpleasant results for fish habitats when the fill is placed <br />_looks funny with mounds of fill placed next to big holes in the <br />ground. The ordinance also contains an objective to minimize damage <br />at development which may compound flooding. What we're concerned <br />about in this section is drainage from development sites and the cumu- <br />lative effects of im2roger development compounding flood problems. <br />This portion of our ordinance has caused the major rub with ndustry <br />n.ings and coastal construction. Some of the more stringent standards, <br />in my opinion make this a viable document, and I'd like to go through <br />a couple of these with you and give you our reason behind them. One <br />is.._tha __=...equal. -volume_ of �taZa, a_�►13 fie., treated_ for any volume of <br />Lha reSMIatory flood or the hundred year flood that would be displaced <br />With this standard, -we rhe main y 00%ifig at <br />Director Davis explained that basically what such a flood <br />protection ordinance would do is say that a developer cannot fill <br />anywhere in a ten year floodplain, any floodplain whether the one <br />in Roseland or along the Indian River, without creating an equal <br />volume of storage in that floodplain. The intent is to retain <br />the volume where flood waters can be stored until they can pass <br />on to the Indian River. Director Davis continued that this <br />provision is necessary in the floodplains in Sebastian and <br />Roseland which are classical flood plains and if you fill them, <br />the water will back up and flood people's properties, but many <br />people feel the Indian River floodplain is unique and more of an <br />estuary type system and doesn't need this provision. <br />Director Davis informed the Board that this ordinance is <br />separate from the Zoning Code; it will require a public hearing, <br />but would not have to go before the Planning 8 Zoning Commission. <br />Discussion arose as to whether the Board wished it to go <br />through the Planning 8 Zoning Commission, and Director Keating <br />noted that, from his standpoint, this just relates to whether the <br />Board wants the advice of the P8Z Commission. He advised that <br />staff already has advertised a public hearing for this ordinance <br />18 <br />_ M M <br />
