Municode Page 6 of 12 Sec. 58-48. Conditional use permit and zoning variance applications. No conditional use permit or zoning variance application shall be approved for a property until the existing ISTS has been confirmed as being of adequate capacity for the anticipated use. If expansion or replacement of the ISTS is required, a site evaluation and design must be approved by the city prior to the approval of a conditional use permit or zoning variance. If the change in use intensifies the strength or quantity of flow for the ISTS, an alternate site must be designated and protected. (Code 1984, § 12.30(4)(G); Ord.
