00j: 0 (f) Zoning Ordinances Article 8 SPECIAL USES and Article 6 APPLICATION OF DIMENSIONAL REQUIREMENTS - provision for the issuance of a Class A Special Use Permit to accommodate requests for modifications of impervious surface requirements for property subject to the Protected Watershed-II overlay zoning district. Marvin Collins stated the staff is recommending that a Class A Special Use Procedure be established that would permit modification of the impervious surface of up to 5%. He reiterated the additional information that would be required as a part of the application. There would be additional standards of evaluation and impervious surface regulations placed on this special use permit. Marvin Collins noted one concern is that a ceiling be put in the provision and enough flexibility be allowed to meet the impervious surface ratio. A justification would be needed in order to use this procedure for modification. Planner Susan Smith stated that OWASA did not have adequate time to review this proposed amendment or the other watershed amendment and asked for an extension of time for receipt of their convents. (e) Zoning Ordinance, Article 6 - APPLICATION OF DIMENSIONAL REQUIREMENT'S - provision for easement over or ownership of land adjoining, or not-adjoining parcels for development to satisfy impervious surface and undisturbed area requirements for property subject to Water Quality Critical Area (WQCA) and Protected Watershed-II (PW-II) overlay zoning districts. Smith indicated this amendment specifically provides an opportunity to use land either adjoining or non-adjoining a piece of property to satisfy both undisturbed area and impervious surface requirements. The acreage must be within the water supply watershed and either owned by the applicant or covered under an easement agreement. Don Cox made comments about satisfying watershed standards off-site: (1) he felt the intent of the watershed standards, particularly as they relate to the impervious surface, is something to be dealt with in small increments of runoff from impervious surfaces for a particular site and not with a large area that cannot be managed, and (2) that providing the correct ratio by adding land set aside somewhere else does not meet the intent of minimizing the amount of runoff where it exists. Chair Willhoit pointed out that the infiltration of the first half inch would be the limiting factor and not the lot size. Marvin Collins indicated that if a person is unable to acquire an easement from a person who owns property adjacent to or does not own the land adjacent to the property► the Special Use Permit procedure gives a third option. Susan Smith listed the remaining Proposed Land Use Plan and Ordinance Text Amendments and commented briefly on each. They are listed below: (a) Land Use Plan - Orange County Highway Classification System. The highway classification of roads has been updated to include 1984 traffic counts.
