•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 within
<br /> a shoreland district in which case the more restrictive rules regarding setbacks would apply. Protected wetlands are
<br /> further defined as follows:
<br /> (1) Type 1--Seasonally flooded basins or floodplains:Type 1 wetlands are seasonally flooded basins or flats
<br /> in which soil is covered with water or is waterlogged during variable seasonal periods but usually is well-drained during
<br /> much of the growing season.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, and includes bottom land
<br /> 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 waterlogged
<br /> within at least a few inches of the surface. 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 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 pondweeds,
<br /> naiads, coontail, water milfoils and other submergent aquatic vegetation.
<br /> (5) Type 5--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 /> (6) Type 6--Shrub swamp:Occurs along sluggish streams or on floodplains. The soil is usually waterlogged
<br /> during the growing season, and is often covered with as much as six inches of water. Vegetation includes alder, willow
<br /> and dogwood.
<br /> (7) Type 7--Wooded swamp:Occurs along sluggish streams, on floodplains, on flat perched depressions and
<br /> in shallow lake basins. The soil is waterlogged to within a few inches of its surface during the growing season and is often
<br /> covered with as much as one foot of water. Vegetation typical to this wetland includes tamarack, white cedar, black
<br /> spruce, balsam fir, red maple and black ash.
<br /> (8) Type 8--Bog:Occurs along sluggish streams, on flat perched depressions and shallow lake basins. The
<br /> soil is waterlogged and supports a spongy covering of mosses. Vegetation typical to this wetland type includes sphagnum
<br /> moss, heath shrubs and sedges. Minnesota bogs contain leatherleaf, Labrador tea, cranberries and pitcher plants.
<br /> Scattered stunted black spruce and tamarack also are common features of bogs.

<br /> Sec. 78-1603. Boundaries of the wetland overlay districts and designation of official city wetland map.
<br /> This section establishes wetland overlay districts. These districts are subject to additional requirements beyond those
<br /> . required by the WCA.The boundaries of the wetland overlay districts are identified graphically on the official city wetland
<br /> map (CWM)which is hereby adopted by reference, a copy of which shall be kept on file in the office of the city clerk and
<br /> shall be available for public review during all normal office hours. Wetlands in addition to those shown on the city wetland
<br /> map may exist, and may be identified by wetland delineations under WCA rules. If a specific wetland delineation has been
<br /> done under WCA rules, then the boundaries of the wetland overlay district for that location will be as shown in the
<br /> delineation. The city may require wetland delineations to determine compliance with WCA rules and to determine
<br /> administrative wetland boundaries; however, property owners may have wetland delineations done for their properties on
<br /> their own initiative.The delineation must be done by a qualified professional according to WCA rules and be acceptable to
<br /> the planning director, who may require review by city consultants or a technical evaluation panel if necessary. Approved
<br /> WCA wetland delineations must be provided to the city in a hard copy format and a CAD or GIS format in Hennepin
