(B) A preliminary evaluation shall consist of:
(1) Flow determination for the dwelling or other establishment;
(2) The investigation of the proposed or existing location of water supply wells within 100 feet of the proposed ISTS, existing and proposed building on the lot, and existing and proposed buried water pipes within 50 feet of the proposed system;
(3) Easements on the lot;
(4) Ordinary high water level of public waters;
(5) Ten-year floodplain designation and flooding elevation from published data as available or from data which is acceptable to and approved by the permitting authority or the DNR;
(6) Property lines;
(7) All required setbacks from the system;
(8) The soils map unit, applicable soil characteristics, and soil suitability as determined by soil borings and percolation tests for each proposed site or installation;
(9) Legal description and lot dimensions; and
(10) Name of property owners.
(Prior Code, Ch. 506 § 8.2)
(C) A field evaluation shall consist of:
(1) Identifying lot lines, lot improvements, and easements;

(3) Depth to the highest known or calculated groundwater table or bedrock;
(4) The existence of lowlands, local surface depressions, and rock outcrops; and
(5) All legal setback requirements from existing and proposed buildings; property lines; sewage tanks; soil treatment systems; water supply wells; buried water pipes and utility lines; the ordinary high water level of public waters; and the location of all soil treatment systems and water supply wells on adjoining lots within 100 feet of the proposed soil treatment system, sewage tank, and water supply well.

(D) A written report on the site evaluation shall be prepared covering, at a minimum, the following:
(1) All of divisions (B) and (C) above;
(2) Dates of preliminary and field evaluations;
(3) A map drawn to scale or dimension, with a north arrow, and including the following:
(a) A horizontal and vertical reference point of soil observation and percolation tests and distance to all required setbacks, lot improvements, easements, ordinary high water mark of public waters, property lines, direction and percent slope;
(b) The location of any unsuitable, disturbed/compacted areas; and
(c) The access route for tank maintenance.
(4) Estimated depth of seasonally saturated layer, bedrock, or flood elevation, if appropriate;
(5) Proposed elevation of the bottom of the soil treatment system;
(6) Final soil sizing factor;
(7) Anticipated construction-related issues; and
(8) Name, address, telephone number, and signature of the individual conducting the evaluation.
