L � <br /> b. The amount of grading exceeds 50 cubic yards or the construction activity involves the disturbance of <br /> more than 5,000 square feet of area; and <br /> c. The redevelopment activity results in a net increase in the square footage of impervious surfaces that <br /> drain to the wetland, or results in the relocation of impervious surfaces closer to the wetland,or results in changes to <br /> drainage patterns (slopes, meander patterns, etc)that the city engineer determines will increase the velocity or rate <br /> of runoff to the wetland. <br /> For new development, all wetlands on the property shall be subject to the buffer requirements. For redevelopment <br /> or other grading or construction situations that are not new development,only the wetland that is potentially <br /> adversely impacted shall be subject to the buffer requirement. In the event that the wetland is on an adjacent <br /> property but near enough to the subject property so that buffers to said wetland would extend into the subject <br /> 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, as defined in circular <br /> 39, "Wetlands of the United States", 1971 edition, United States Department of the Interior, unless the wetland is <br /> within a shoreland district in which case the more restrictive rules regarding setbacks would apply. Protected <br /> wetlands are further defined as follows: <br /> � (1) Type 1--Seasonally flooded basins or floodplains:Type 1 wetlands are seasonally flooded basins or <br /> flats in which soil is covered with water or is waterlogged during variable seasonal periods but usually is well-drained <br /> during much of the growing season.Type 1 wetlands are located in depressions and in overflow bottom lands along <br /> water courses.Vegetation varies greatly according to the season and duration of the flooding,and includes bottom <br /> land hardwoods,as well as herbaceous plants. <br /> (2) Type 2--Inland fresh meadow:Occurs along the shallow edges of lakes,marshes and floodplains, or in <br /> perched depressions.The soil is usually without standing water during much of the growing season, but is <br /> waterlogged within at least a few inches of the surface.Vegetation includes grasses,sedges, rushes and various <br /> herbaceous plants. <br /> (3) Type 3--Inland shallow fresh marsh:Soil is usually water logged during the growing season,often <br /> covered with as much as six inches or more of water.Vegetation includes grasses, bulrushes, cattails,arrowheads, <br /> smartweeds and other emergent aquatic vegetation. <br /> (4) Type 4--Inland deep fresh marsh:Soil covered with six inches to three feet or more of water during <br /> growing season.Vegetation includes cattails, reeds, bulrushes and wild rice.Open water areas may contain <br /> pondweeds, naiads, coontail, water milfoils and other submergent aquatic vegetation. <br /> (5) Type S--Inland open fresh water:Water is usually less than ten feet deep and is fringed by a border of <br /> emergent vegetation.Vegetation includes pondweeds, naiads, coontail, water milfoils and other submergent aquatic <br /> vegetation. <br />
