25-5 DRINKING WATER SOURCE PROTECTION OVERLAY ZONE: Zone 3

All commercial and industrial uses in the underlying zone are conditional uses in Zone 3. Single family or multi-family residential uses may be permitted or conditional as is determined in the underlying zone. Cluster subdivisions, mobile home parks, multi-family or other groups of dwellings that have an actual lot size of less than one acre are a conditional use and restricted to be located where a sanitary system can be made and approved by the Tooele County Health Department and which will not contaminate the aquifer. All conditional use permits, subdivision, planned unit development and rezone applications in Zone 3 will be reviewed by the Tooele County Health Department. A conditional use permit, subdivision or planned unit development may be approved only when it is determined that under best management practice the use mitigates activities that are a contamination of ground-water resources. A rezone application may have a favorable recommendation only when it is determined that the density will not present any danger that may contaminate ground-water resources. A geotechnical, hydro-geologic and chemical evaluation study by licensed and qualified firms or persons may be required by the planning commission, Tooele County Health Department, or engineering staff to assess the effects of a potential spill in reaction to geologic conditions.
