1. All lots proposed for individual sewage treatment systems <br />shall be evaluated by the Ramsey Plumbing Inspector in accordance <br />with this section and in accordance with Chapter 150.01 of this <br />code. <br />2. Prior to final plat approval, and in addition to the platting <br />requirements of the City Code the subdivider shall file a final <br />grading plan of the plat to be developed which shall contain the <br />following information: <br />a. All legal setback requirements from existing and <br />proposed buildings, property lines, sewage tanks, soil treatment <br />areas, water supply wells, buried water pipes and utility lines, <br />lakes, rivers, streams, large trees and the location of all such <br />improvements on adjoining lots within one hundred fifty (150) <br />feet of the site; <br />b. Slope; <br />c. The existence of lowlands and local surface depressions; <br />d. Depth of the seasonal high ground water table; <br />e. Soil conditions, properties and permeability; <br />f. Surface water flooding probability. <br />3. The evaluation shall begin with evaluation of the data <br />contained on the final grading plan described in paragraph 2 <br />above, along with an evaluation of the following: Preliminary <br />plat, if applicable, flood plain and soil survey maps, soil <br />interpretation sheets, experience and any other relevant <br />information. If this evaluation in the opinion of the City <br />Engineer, yields enough information and the site is suitable, <br />approval may be given for the installation of the standard system <br />of Section 150.014F. If the preliminary evaluation does not <br />produce sufficient information, a field evaluation shall be <br />required, including but not limited to slope and setback <br />measurement, soil borings and percolation tests. <br />4. If at any time during the course of the preliminary or field <br />evaluation, limiting characteristics for a standard system are <br />discovered, the City Engineer shall determine if an alternative <br />site for a standard system is available on the affected parcel of <br />real property; and if such a site is available, then the City <br />Engineer shall require an evaluation of the alternative site. <br />5. If a detailed field evaluation is deemed necessary, the City <br />Engineer shall employ the following procedures: <br />a. A preliminary soil boring shall be required in the <br />center of the proposed individual sewage treatment system in <br />accordance with the procedures presented in Section 170.038H <br />
