7 <br />property. <br />This proposed amendment is designed to- <br />1 . Require formally prepared site plans for those projects exceeding established <br />stormwater disturbance thresholds for residential projects. <br />Submittal of formal site plans is already required for all non - residential projects <br />regardless of the proposed land disturbance activity. <br />2. Incorporate references within various locations of the UDO identifying which <br />land development projects need to comply with these standards in an effort to <br />eliminate confusion and provide definitive application submittal standards. <br />3. Add language requiring stormwater management plans for minor and major <br />subdivisions where anticipated land disturbance activities would exceed <br />established thresholds. <br />Both Planning and Erosion Control staff agree potential problems can be <br />eliminated if there is a formal stormwater management plan approved during <br />the subdivision review and approval process. <br />Staff identified 3 options with respect to addressing existing language in Section 2.4.1 <br />requiring a professionally prepared site plan for any project within the University Lake <br />Watershed Protection Overlay District- <br />- Option A: Leave as is — no change. (i.e. only properties in the University <br />Lake Watershed impacted). <br />— Option B: Amend section requiring all watershed overlay districts with a <br />6% impervious surface limit be treated the same (i.e. professional site <br />plan). <br />— Option C: Eliminate requirement all together and require professionally <br />prepared site plans only when stormwater thresholds are exceeded. <br />After reviewing comments from OWASA (refer to Attachment 4) and after discussing <br />the issue with the Planning Board, staff supports Option C as detailed above. <br />2. Analysis <br />As required under Section 2.8.5 of the Orange County Unified Development <br />Ordinance, the Planning Director is required to: `cause an analysis to be made of <br />the application and, based upon that analysis, prepare a recommendation for <br />consideration by the Planning Board and the Board of County Commissioners'. <br />The proposed amendment is designed to incorporate established stormwater <br />management land disturbance thresholds into existing language within the UDO <br />requiring formal site plan preparation and submittal by an applicant when said <br />thresholds are exceeded. <br />By modifying existing language we hope to eliminate unnecessary cost for the <br />applicant, with respect to the completion of multiple site plans, and provide sufficient <br />detail to residents, property owners, and developers on when formal site plan <br />preparation is necessary. <br />The amendment is also designed to provide a `central site plan' for review to ensure <br />staff is reviewing and taking action on the same document to avoid confusion and <br />3 <br />
