Certain wetlands are exempt from wetland regulation: Category IV wetlands less than 8,000 square feet in area and Category III wetlands less than 500 square feet in area having only one wetland class, which is not forested, and which is hydrologically isolated. The City may allow buffer width reductions in some instances where buffers have been legally altered in the past, and enhancement of buffers are proposed. Buffers are also required when the buffers for wetlands on adjacent properties extend onto the subject site. ❑1 ❑2 The tocation of streams lWood Creekl must be identified and buffers provided when the channel occurs on or adjacent to the site. The streams must be reted and huffers provided per Sections 37.130 and 37.740 of the Zoning Code.
