� For purposes of this section, "the potential to adversely impact a wetland"exists when all <br /> � of the following three conditions exist: <br /> a. The portion of the property disturbed by construction or land alteration activity � <br /> drains to the wetland; and <br /> b. The amount of grading exceeds 50 cubic yards or the construction activity <br /> involves the disturbance of more than 5,000 square feet of area; and <br /> c. The redevelopment activity results in a.net increase in the square footage of <br /> impervious surtaces that drain to the wetland, or results in the relocation of <br /> � impervious surtaces closer to the wetland, or results in changes to drainage <br /> patterns(slopes, meander patterns, etc)that the city engineer determines will � <br /> increase the velocity or rate of runoff to the wetland. <br /> For new development, all wetlands on the property shall be subject to the bufFer <br /> requirements. For redevelopment or other grading or construction situations that are not <br /> new development, only the wetland that is potentially adversely impacted shall be subject <br /> to the buffer requirement. In the event that the wetland is on an adjacent property but <br /> near enough to the subject property so that buffers�to;said wetland would extend into the <br /> subject property, the buffer requirements apply. � <br /> (Ord. No. 28 3rd series, § 1, 8-22-2005) <br /> DIVISION 2. <br /> DESIGNATION OF PROTECTED WETLANDS <br /> Sec. 78-1602.Wetland types. <br /> The wetlands protected and regulated by this section are types 1, 2, 3, 4, 5, 6, 7, and 8 wetlands, <br /> as defined in circular 39, "Wetlands of the United States", 1971 edition, United States Department of the <br /> Interior, unless the wetland is within a shoreland district in which case the more restrictive rules regarding <br /> setbacks would apply. Protected wetlands are further defined as follows: <br /> (1) Type 1—Seasonally flooded basins or floodplains:Type 1 wetlands are seasonally <br /> flooded basins or flats in which soil is covered with water or is waterlogged during <br /> variable seasonal periods but usually is well-drained during much of the growing season. <br /> Type 1 wetlands are located in depressions and in overflow bottom lands along water <br /> courses. Vegetation varies greatly according to the season and duration of the flooding, <br /> and includes bottom land hardwoods, as well as herbaceous plants. <br /> (2) Type 2—Inland fresh meadow:Occurs along the shallow edges of lakes, marshes and <br /> floodplains, or in perched depressions. The soil is usually without standing water during <br /> much of the growing season, but is waterlogged within at least a few inches of the <br /> surtace. Vegetation includes grasses, sedges, rushes and various herbaceous plants. <br /> ' (3) Type 3—Inland shallow fresh marsh:Soil is usually water logged during the growing <br /> season, often covered with as much as six inches or more of water. Vegetation includes , <br /> grasses, bulrushes, cattails, arrowheads, smartweeds and other emergent aquatic <br /> vegetation. <br /> (4) Type 4--Inland deep fresh marsh:Soil covered with six inches to three feet or more of <br /> water during growing season.Vegetation includes cattails, reeds, bulrushes and wild rice. <br /> Open water areas may contain pondweeds, naiads, coontail, water milfoils and other <br /> submergent aquatic vegetation. <br />
