(c)

Sulfidic material -- a strong "rotten egg" smell generally is noticed immediately after the soil test hole is dug.   

(d)

Gleyed soils -- soils that are predominantly neutral gray, or occasionally greenish or bluish gray in color within twelve (12) inches from the bottom of the O-horizon. (The Munsell Soil Color Charts have special pages for gleyed soils).

(e)

Soils with a matrix chroma of 0 or 1 and values of 4 or higher within twelve (12) inches from the bottom of the O-horizon.

(f)

Within twelve (12) inches from the bottom of the O-horizon, soils with a chroma of 2 or less and values of 4 or higher in the matrix, and mottles with a chroma of 3 or higher.

(g)

Within twelve (12) inches from the bottom of the O-horizon, soils with a matrix chroma of 3 and values of 4 or higher, with 10 percent or more low-chroma mottles, as well as indicators of saturation (i.e., mottles, oxidized rhizospheres, concretions, nodules) within six (6) inches of the soil surface.

(2)

All colors listed above are moist colors as determined by comparison with the most recent Munsell Color Book.  Definitions for diagnostic horizons may be found in Keys to Soil Taxonomy, A.I.D., U.S.D.A. publication.

(3)

The soil surface is the top of the mineral soil, or for soils with an O-horizon, the soil surface is measured form the top of the O-horizon.  

(4)

Fresh leaf or needle fall that has not undergone observable decomposition (the litter layer) is excluded from soil and may be separately described.   

c)

Isolated Wetlands and Seasonal Wetlands are defined elsewhere in these regulations and need not necessarily meet the above requirements.

d)

In situations where the natural vegetative community may have been destroyed, as for example by lawn or agricultural use, the Commission may determine the area to be Freshwater Wetland on the basis of annual hydric soil saturation alone (as defined above) or, at the request of the applicant or land owner, may defer the determination until the natural vegetation has regrown.

e)

In situations where the Commission determines that the natural vegetative community has been destroyed in violation of the Ordinance, the Commission may itself elect to defer any determination of the presence or absence of, or the boundaries of, a Freshwater Wetland until the natural vegetation has regrown,
