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.

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. For purposes of this ordinance, soils that meet at least an A+4 criteria during a soil and site evaluation procedure shall not be considered hydric soils. *Note that the U.S. Department of Agriculture - Natural Resources Conservation Services, Section II Technical Guide - Hydric Soil Interpretations list of hydric soils as a guideline listing soil types that may meet hydric soil conditions.
