The following definitions shall also apply in this chapter.

(1) A+4. Refers to the “A” soil horizon which is a layer of mineral soil or soil material approximately parallel to the land surface and typically at ground surface and four (4) inches of soil below the “A” horizon that is free of any redoximorphic soil features that would be indicative of soil saturation and consist of soil diagnostic characteristics indicative of “B”, “C” or “E” horizons. For purposes of this ordinance this is the soil criteria used for all lands being subdivided.

(2) ATU. An abbreviation for “aerobic treatment unit”.

The concept of hydric soils includes soils developed under sufficiently wet conditions to support the growth and regeneration of hydrophytic vegetation. Soils that are sufficiently wet because of artificial measures are included in the concept of hydric soils. Also, soils in which the hydrology has been artificially modified are hydric if the soil, in an unaltered state, was hydric.

Public and Commercial Buildings - when there is a proposed change in occupancy of a structure, or the proposed modification affects either the type or number of plumbing appliances, fixtures or devices discharging to the system.

Dwellings and Residences - when there is an increase or decrease in the number of bedrooms and/or additions, interior modifications, renovations or remodeling or any combination thereof that enlarges or impacts a dwelling’s building area and/or floor area by 25% or greater.
