A potable water <br /> supply that can provide a consistent source of safe and clean water adequate for human consumption, <br /> cooking, and sanitary purposes for the proposed new home needs to be established prior to the issuance of <br /> building permits (2016 CA Plumbing Code, Section 601.2). <br /> The provision of a reliable potable water source and documentation that the parcel can accommodate the <br /> OWTS and 100% replacement area for all three homes within the required setbacks from any water well and <br /> canals must be submitted prior to the issuance of a building permit. The site map for the building permit for <br /> the new dwelling unit must be drawn to scale and must show the location of all buildings, driveways, OWTS, <br /> the OWTS replacement areas and any water wells and surface water within 200 feet of the proposed OWTS <br /> and replacement areas. The dispersal area for the OWTS and reserved replacement area cannot be driven <br /> over, paved over, or used for any other purpose. <br /> If you have any questions please contact Michael Kith, REHS, Program Coordinator at .mkith(@.s'_qov.org or <br /> (209) 468-3444. <br /> ,� Michael Kith, REHS <br /> ogram Coordinator <br /> c: Kornai Atwal <br /> 1868 E.
