124 6 surface. Higher impervious surface limits in severed areas would be expected to lead to greater runoff into sensitive streams. 5. An opinion that if Seven Mile Creek reservoir is not going to be built, the entire Critical Area associated with the sub - watershed should be removed; the area is well- protected with the "Protected" designation and AR (Agricultural Residential) zoning. As the memo from ERCD in Attachment 7 indicates, there are significant aquatic resources in the Seven Mile Creek area that warrant continued protection. 6. A question regarding where future water supplies will come from and an opinion that other reservoir possibilities need to be looked at if economic development is desirable. See discussion above under the "Planning Board Ordinance Review Committee" heading regarding additional future water sources for Orange County. 7. An opinion that cutting density in half and reducing impervious surface will make a 20- acre tract undevelopable for a subdivision — the stated purpose of acquiring the property in the vicinity of Dimmocks Mill Road. Although one may not be able to have as many lots in a future subdivision as is currently potentially allowed, this does not render a property " undevelopable." As was discussed at the Quarterly Public Hearing, often soil types in the county do not allow for smaller -sized lots because soils do not perk well. While the zoning district may allow for lots as small as 40, 000 square feet (0.92 acres), developers often need to plat larger lots in order to locate a well, septic system, and septic repair area on a lot. 8. A statement that, when developing a subdivision, the subdivision's roads are subtracted from the 6% impervious surface limit so the resulting impervious surface limit is less than 6% on a per -lot basis. This is correct. Lots in subdivisions fall under the provisions adopted with subdivision approval which may be different from long- existing lots or parcels located outside of major subdivisions. 9. A question regarding whether a destroyed non - conforming house can be re -built to the same size. Yes, it can be rebuilt since the lot has not changed. 10.A concern that Interstate 85/40 is very close to Lake Ben Johnson and what would happen if there is a chemical spill on the highway. Proximity to the Interstate is one of the reasons the Town of Hillsborough did not construct a reservoir on Seven Mile Creek and instead chose West Fork on the Eno. Orange County Emergency Services Department has a Hazard Plan in place that includes addressing spills on the highway or railroad tracks. 11. An opinion that some driveway surfaces should not be considered impervious surface. Driveways are counted because the County does not count other semi pervious areas such as lawns which can be up to 70% impervious. 12. An opinion that regulations do not allow the county to grow and increase tax base. Orange County has designated targeted areas for growth and is pursing policies and programs to bring economic development to these targeted areas. There are numerous examples throughout the country where unplanned, haphazard growth has led to suburban sprawl and inefficient provision of services as a result of the sprawl. Orange County endeavors not to re- create problems other jurisdictions are dealing with due to inefficient growth patterns. 13.A question on whether non - residential uses are allowed in the Critical Area. In the Upper Eno Critical Area, non - residential uses are allowed only in the Cedar Grove Rural Community Activity Node, in conformance with the Zoning Ordinance. 14.A question on whether input has been received from the Town of Hillsborough or Orange - Alamance Water System (OAWS). Town of Hillsborough staff is aware of the proposed changes and may provide comment at a later date. County staff has communicated with
