c Q � � 41 <br /> Jobsis reiterated the fact that the topography <br /> makes this development more restrictive and it <br /> would be more difficult to build a loop road. <br /> Mr. Gambill emphasized locations of other <br /> subdivisions within the area that have cul-de- <br /> sacs. He felt what was being asked by the <br /> developer is not unreasonable. <br /> Price asked about the sewer lines for the backup <br /> system. Cameron responded that with average <br /> slopes, average soils, approximately ten thousand <br /> square feet is needed for the system and repair <br /> system for a three bedroom house. <br /> Reid asked about the size of the dwelling units <br /> noting that the number of bedrooms is the <br /> determining factor for the septic system. <br /> Cameron responded that Stimpson had indicated <br /> there were some marginal soils.

Willis noted <br /> that the Health Department will not sign off on <br /> the final plat unless each lot is found to be <br /> adequate for the septic system. They certify on <br /> each plat that there is sufficient area for <br /> septic system and repair area. All of the <br /> concerns being expressed are addressed by the <br /> Environmental Health Department. <br /> Price continued asking about the natural springs <br /> on the property.

Cameron stated that <br /> they are not indicated as intermittent streams on <br /> USGS maps and do not require stream buffers. <br /> Katz asked if Eno State Park has reviewed and <br /> commented on this subdivision. Cameron responded <br /> that they were concerned with drainage from the <br /> site. Discussion with the Erosion Control . <br /> Supervisor had indicated the design meets the <br /> County Stormwater Management requirement by <br /> having larger lots and grass swales. Detention <br /> ponds would create more disturbance in the buffer <br /> areas. Mr. Gambill noted that the County <br /> Ordinance permits 26% impervious surface on this <br /> tract; however, there will only be 7% impervious <br />
