Soil Cl-ssLfication is where soil particle sizes or texture's are specified in this regulation, they refer to the Gufde for USDA Soil Textural Classification. Soil Trea~ ent Area is an area where sewage tank effluent is treated and d~sposed of below the ground surface by filtration and percolation through the soil and also by evaporation, and includes those systems commonly known as seepage bed, trench drainfield, d~sposal field, and also includes mounds and seepage pits. S~qr~clnrd System is an individual sewage treatment system employing a sewage t~nl~ and the soil treatment system cor-mon]y known as seepage bed or trenches, drainfeld or leachfeld. Surface Water FloodLug is the 100 year flood plain along rivers and streams as deft-ed by'the DNR or, in the absence of such data, the highest flood level of record; on lakes, kigh water levels as determined or recorded by the Department of Natural Resources or, in the case of no DNR record, by local records or e×per~ence. Other surface water flooding 'or high water areas should be determined by local information. Valve Box is any device which can stop sewage tanl~ effluent from flowing to a portion of the soil treatment area, and includes but is not l~m~ted to caps or plugs on d~stribution or drop box outlets, divider boards, butterfly valves, gate valves or other mechanisms.

Season~Uy t~igh Water Table is a perched water table or a saturated soil condition whfch occurs during wet seasons of the year. Normal (or Ora~nary) High Water Mark is a mark delineating the highest water level which has been maintained for a s~ff~c~ent period of time to leave evidence upon the landscape. The normal high water mark is commonly that point where the natural vegetation changes from predominantly aquatic to predom~nandy terrestrial. Watertight is when constructed so that no extarnal water can enter. Water Usage shah be estimated by the best current available data provided by the agency if actual measurements are unavailable. $.30.03 Permi~ SubdlvisionL No person, firm or corporation shall install, alter, repair or extend any individual sewage d~sposal system in the City without ~_rst obtaining a perm/t therefore from the council or its authorized representative for the specific installation, alteration, repair or extension, and at the time of applying Printed 12/28/90 Page 239
