She asked the applicant to speak to <br /> 5 those concerns. <br /> 6 David Barcal said he conducted a preliminary soils analysis for the site, and the majority <br /> 7 is labeled conventional soil (24-30 inches deep of usable soil), providing good filtration and <br /> 8 downward flow as opposed to upwards or outwards or lateral flow. He said no lots are platted <br /> 9 within riparian setbacks or wetlands. For marginal soils requiring drip systems, they would provide <br /> 10 pre-treatment with UV disinfection and media filters for better water quality. <br /> 11 Commissioner Fowler asked if all the septic systems could be put on conventional soil. <br /> 12 David Barcal said at least at a desktop level, they can fit a four-bedroom system for each <br /> 13 lot, all on conventional soils. <br /> 14 Commissioner Carter said she recalls from the packet that 10 acres of the property fall <br /> 15 under the marginal soil category. She asked if that is included in the lot sighting shown in the <br /> 16 proposal. <br /> 17 David Barcal said it could be 10 acres total, but there are only a few sites that have <br /> 18 marginal soil within the property lines of a lot. He said they would design the septic system in the <br /> 19 conventional soils and, if needed, would use the drip system for the repair field. He explained that <br /> 20 this would make repair field cycling possible. <br /> 21 Vice-Chair Hamilton asked for more information on the repair field. <br />
