ARTICLE XI. WETLANDS PROTECTION Pa�e 2 of 12 impervious surfaces that drain to the wetland, or results in the relocation of impervious surfaces closer to the wetland, or results in changes to drainage patterns (slopes, meander patterns, etc) that the city engineer determines will increase the velocity or rate of runoff to the wetiand. For new development, all wetlands on the property shall be subject to the buffer requirements. For redevelopment or other grading or construction situations that are not new development, only the wetland that is potentially adversely impacted shall be subject to the buffer requirement. In the event that the wetland is on an adjacent property but near enough to the subject property so that buffers to said wetland would extend into the subject property, the buffer requirements apply. (Ord. No. 28 3rd series, § 1, 8-22-2005) DIVISION 2. DESIGNATION OF PROTECTED WETLANDS Sec. 78-1602. Wetland types. The wetlands protected and regulated by this section are types 1, 2, 3, 4, 5, 6, 7, and 8 wetlands, as defined in circular 39, "Wetlands of the United States", 1971 edition, United States Department of the interior, unless the wetland is within a shoreland district in which case the more restrictive rules regarding setbacks would apply. Protected wetlands are further defined as follows: (1) Type 1--Seasonally flooded basins or floodplains: Type 1 wetlands are seasonally flooded basins or flats in which soil is covered with water or is waterlogged during variable seasonal periods but usually is well-drained during much of the growing season. Type 1 wetlands are located in depressions and in overflow bottom lands along water courses. Vegetation varies greatly according to the season and duration of the flooding, and includes bottom land hardwoods, as well as herbaceous plants. (2) Type 2--Inland fresh meadow: Occurs along the shallow edges of lakes, marshes and floodplains, or in perched depressions. The soil is usually without standing water during much of the growing season, but is waterlogged within at least a few inches of the surface. Vegetation includes grasses, sedges, rushes and various herbaceous plants. (3) Type 3--In/and shallow fresh marsh: Soil is usually water logged during the growing season, often covered with as much as six inches or more of water. Vegetation includes grasses, bulrushes, cattails, arrowheads, smartweeds and other emergent aquatic vegetation. (4) Type 4--lnland deep fresh marsh: Soil covered with six inches to three feet or more of water during growing season. Vegetation includes cattails, reeds, bulrushes and wild rice. Open water areas may contain pondweeds, naiads, coontail, water milfoils and other submergent aquatic vegetation. (5) Type S--Inland open fresh water. Water is usually less than ten feet deep and is fringed by a border of emergent vegetation. Vegetation includes pondweeds, naiads, coontail, water milfoils and other submergent aquatic vegetation. (6) Type 6--Shrub swamp: Occurs along sluggish streams or on floodplains. The soit is usually waterlogged during the growing season, and is often covered with as much as six inches of water. Vegetation includes alder, willow and dogwood. (7) Type 7--Wooded swamp: Occurs along siuggish streams, on floodplains, on flat perched depressions and in shallow lake basins. The soil is waterlogged to within a few inches of its surface during the growing season and is often covered with as much as http://library2.municode.com/default/DocView/13094/1/109/120 1/18/2008
