Zoning and lot sizes will be regulated to allow <br />adequate space for onsite septic systems in residential <br />areas. Current rules require adequate space for a <br />second drain field on each residential tract, in case the <br />first one fails. <br />B. All onsite septic systems in the City are inspected bi- <br />annually to insure the correct operation of these <br />systems. Inspections are performed by the City's <br />contracted inspector. <br />C. A backup plan for providing a City operated sanitary <br />sewer system has been developed and will be put in <br />place if necessary in any area of the City where onsite <br />septic systems cannot operate. <br />Within these goals the following specific items have been <br />implemented: <br />City of Gem Lake Comprehensive Plan I page 7-3 <br />
