5 <br /> involved the granting of a perpetual easement on adjoining property <br /> [rather than actual fee simple acquisition] , limiting development and <br /> satisfying the impervious surface ratios indirectly. Of the two <br /> alternatives, the County Attorney felt that the latter one offered a <br /> possible solution to the Fire Department' s problem. <br /> Although the Fire Department has not actively pursued such an <br /> amendment, recent events have suggested that changes be considered <br /> again. One situation involved the proposed construction of a new school <br /> located on a site partially in University Lake Watershed. To satisfy <br /> impervious surface limits and permit construction to proceed, a solution <br /> involving collection and disbursement of stormwater outside the <br /> watershed was developed. Although not in Orange County' s jurisdiction, <br /> the school situation highlighted a potential problem for the County, <br /> given the approval of bond funding for new school construction. <br /> More recently, Orange County has been working toward identifying <br /> and constructing sites for recycling centers. The difficulty of <br /> installing such centers in watersheds was emphasized when a <br /> determination was made that an existing "green box" site could not be <br /> used because of insufficient land area being available to satisfy <br /> impervious surface ratios; While the site in question is existing, the <br /> same concern applies to new sites, several of which are to be located in <br /> watershed areas. As an example, recycling centers would have an <br /> impervious surface area of approximately one acre. To adhere to a 12 <br /> percent impervious surface limit, the total site would have to be <br /> slightly more than eight acres in size. <br /> While the focus to date has been almost exclusively on public <br /> facilities, the same difficulties could just as easily be experienced by <br /> privately owned, non-residential development. Examples which come to <br /> mind are existing churches, community centers or neighborhood <br /> convenience stores wanting to expand but lacking sufficient area to <br /> satisfy impervious surface standards. <br /> The current difficulties are addressed in the State-mandated <br /> watershed protection standards which must be implemented by Orange <br /> County no later than January 1, 1994 . The original schedule for <br /> implementation of the watershed protection standards called for a public <br /> hearing in May of 1993 . However, because of pressing nature of other <br /> issues, the public hearing was moved back to August 1993 . <br /> In the State-mandated standards, localities will have a choice of <br /> adopting "low" or "high" density options. The low density option relies <br /> on minimum lot sizes or impervious surface limits as the basis for <br /> watershed protection. This varies with current County standards which <br /> employs both lot size and impervious surface limits. <br /> In contrast, the high density option allows greater impervious <br /> surface coverage if engineered stormwater controls [wet detention <br /> basins] are installed to control the first inch of rainfall. The amount <br /> of impervious surface or built upon area is limited to 30 percent for <br /> residential development and 70 percent for non-residential in that <br /> portion of a watershed beyond a Critical Area. In the case of non- <br />
