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 39,
<br /> "Wetlands of the United States", 1971 edition,United States Department of the Interior,unless the wetland is within a shoreland
<br /> district in which case the more restrictive rules regarding setbacks would apply. Protected wetlands are further defined as follows:
<br /> (1) Type 1--Seasonally flooded basins oi-floodplains:Type 1 wetlands are seasonally flooded basins or flats in
<br /> 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
<br /> along water courses.Vegetation varies greatly according to the season and duration of the flooding,and includes
<br /> bottom 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 perched
<br /> 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
<br /> plants.
<br /> (3) Type 3--Inland shallow fresh marsh: Soil is usually water logged during the growing season,often covered with
<br /> as much as six inches or more of water.Vegetation includes grasses,bulrushes,cattails,arrowheads,smartweeds
<br /> 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 growing
<br /> 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 S—Inland open fresh water: Water is usually less than ten feet deep and is fringed by a border of emergent
<br /> 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 during
<br /> 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 in
<br /> shallow lake basins. The soil is waterlogged to within a few inches of its surface during the growing season and
<br /> is often covered with as much as one foot of water. Vegetation typical to this wetland includes tamarack,white
<br /> cedar,black 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 soil is
<br /> waterlogged and supports a spongy covering of mosses. Vegetation typical to this wetland type includes
<br /> sphagnum moss,heath shrubs and sedges. Minnesota bogs contain leatherleaf, Labrador tea,cranberries and
<br /> pitcher plants. 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 map
<br /> (CWM)which is hereby adopted by reference,a copy of which shall be kept on file in the office of the city clerk and shall be
<br /> available for public review during all normal office hours. Wetlands in addition to those shown on the city wetland map may exist,
<br /> and may be identified by wetland delineations under WCA rules.If a specific wetland delineation has been done under WCA rules,
<br /> then the boundaries of the wetland overlay district for that location will be as shown in the delineation. The city may require
<br /> wetland delineations to determine compliance with WCA rules and to determine administrative wetland boundaries; however,
<br /> property owners may have wetland delineations done for their properties on their own initiative. The delineation must be done by a
<br /> qualified professional according to WCA rules and be acceptable to the planning director,who may require review by city
<br /> consultants or a teehnical evaluation panel if necessary. Approved WCA wetland delineations must be provided to the city in a
<br /> hard copy format and a CAD or GIS format in Hennepin County coordinates. The planning director will have the approved WCA
<br /> wetland delineations shown on the official city wetland map.Public waters are not included in the overlay district,unless a wetland
<br /> is part of a public water.
