For all lots in unsewered areas that require platting or a waiver of platting, the landowner shall submit to the city a soil boring and analysis report prepared by a licensed designer or professional engineer trained in subsurface sewage treatment systems. The analysis shall show the existence of an adequate land area of suitable soils that will accommodate at least two (2) sites for a soil treatment system on each lot, taking into account depth to water table, soil types and conditions, topographic features, flooding potential and mandatory setback requirements, as dictated by this code and any applicable state and federal regulations. The evaluation of the soils and the soil borings as well as the two (2) potential locations of the on site subsurface sewage treatment system shall be submitted to the department for review and approval prior to any preliminary or final plat approval or waiver of platting being given for the subject property. Failure to provide the information required by this section or failure to have at least two (2) potential sites for a soil treatment system on each lot shall be grounds for denial of the plat or grounds for denial of the waiver of platting.
