The surrounding land � use consists of single-family homes, wetland, and scattered forest. All identified wetlands and areas were classified according to the Cowardin et al. and Circular 39 classification systems and staked with lath or pin flags. Please find within the Technical Documentation Section; field data sh�ets, � plant indicator status information, soil survey infarmation, and wetland definition informatioll. ' Svoboda Ecological Resources 744 Brown Roaci North Project No.: 2007-081-03 ] 'T'ed Schultze ' , � METHODS � The methods used to delineate the subject parcel are as described in the 1987 US Army Corps of Engineers Wetlands Delineation Manual and the 2007 Midwest Region Supplement Manual. In the � 1987 Manual, the methods used were described under the "routine" methods for sites less than 5 acres. This methodology is followed in order to assess whether the three parameters of a wetland are met for areas on the subject parcel. The three parameters required under normal circumstances in � order to delineate a wetland are described in the Technical Documentation Section. The Midwest Regional Supplement Wetland Delineation Manual is also being utilized to increase ' the accuracy of our wetland boundaries. This addendum to the original 87 Manual was created to address the many regional differences that affect wetlands and the delineation methods used throughout the country. The following explanations are passages from that document. � "This Regional Supplement is part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland- � delineation procedures. Regional differences in climate,geoloay,soils,hydrology� plant and animal communities,and other factors are important to the identification and tiunctioning of wetlands.These differences cannot be considered adequately in a � single national manual. The development of this supplement follows National Academy of Sciences recommendations to increase the regional sensitivity of wetland-delineation methods(National Research Council 1995).The intent of this supplement is to bring the Corps Manual up to date with current knowledge and � practice in the region and not to change wetland boundaries." "...This Regional Supplement is designed for use with the current version of the Corps Manual (Environmental Laboratory 1987)and all subsequent versions.Where differences in � the two documents occur, this Regional Supplement takes precedence over the Corps Manual for applications in the Midwest Region." � National Wetland Inventory(NWI) maps (Figure 2),SoiZ Survey of Heranepin Coacnty maps (Figure 3), Minnesota Protected Waters maps (Figure 4),and 2006 aerial photographs were reviewed prior to the site visit to identify areas that may be wetlands. Areas illustrating evidence of wetland conditions � were examined in greater detail during the field survey. Vegetation, soils and hydrology were examined (as outlined in the 1987 Manual) and �ised to characterize wetland types and determine wetland boundaries. Sample transects were established in representative wetland-to-upland � transition zones in order to characterize the vegetation, soils, and hydrology of the site. Transects consisted of representative upland sample point(s) and representative wetland sample point(s). Information obtained from the sample points can be found on the field data sheets located in the � Technical Documentation Section. Wetland boundaries were marked at the site by blaze-orange"wetland boundary"flagging attached � to 4-foot wooden lath or pin flags. Where vegetation was dense,to assisC in locatin�the tlagged lath (wetland edge), a second piece of tlagging was attached to a nearby tree or shrub branch. The "wetland boundary"is considered to be the topographically highest extent of the wetland basin;areas � below the staked boundary met the three required wetland criteria while areas al�ove were lacking in � Svoboda Ecological Resources 744 Broe��n Road North ProjecC No.:2007-081-03 2 Ted Schultze ' , � one or more of these criteria. Wetland classification followed methods described by Cowardin et al. (1979) and used in the NWI (e.g. PEMB, PSS1C, etc.), completed by the U.S. Fish and Wildlife � Service. The Circular 39 classification (Shaw and Fredine 1956) is also given (e.g. Type l, Type 2...etc.). The indicator status of plants, as described in The Technical Documentation Section,was � determined Lising the National List of Plant Species That Occur in Wetlands — Region 3 (Sabine 1999). � Results; Background Information- (Office-Based Investigation) The NWI map (Excelsior Quadrangle) illustrates one wetland complex along the southern edge of � the subject parcel (Figure 2).

The wetland is dominated hy reed canary grass (Phalar-i�s c�rundinacec�), lake bank sedge (C��rex lacustris), green ash (Fj�•aritzus pefa�asYlvczraica),box elder(Acer negundo)and American elm(Ulmus a�2er-icnna). This classi�i�ation � is consistent with the NWI classification. The adjacent upland area is dominated by common buckthorn (Rhamrzus catharticc�), and various ' hardwoods. Wetland 1 was delineated by approximately 451ath. The majority of the wetland boundary exhi�ited � a rather distinct topographic edge. Additionally, there was a distinct shift between hydrophytic and non-hydrophytic vegetation dominance. SER ecologists typically placed the wetland boundary along the edge of reed canary grass(wetland)and common buckthorn (upland). SER ecologists observed � rather high water levels, since AugusC the area has received approximately l6" of precipitation according to the Chanhassen Weather Station. The soils in the upland were determined to be non- hydric but were saturated at 10" below the soil surface. Also, according to the upland data form, ' hydrophytic vegetation was dominant in the upland. The upland sample point was int�uuenced by adjacent hydrophytic trees. The sample location was approximately 8 feet away from the wetland � boundary;proper sampling protocol requires a 30-foot radius for the tree stratum. Thus,resulting in hydrophytic dominance on the upland data form. � Svoboda Ecological Resources 744 Brown Roacl North Project No.: 2007-081-03 7 TedSchultze � , 1 DI I SCUSS ON � SER completed all on-site delineations based on the three required technical criteria as outlined by the 1987 Manual: the presence of hydric soils, a predominance of hydrophytic vegetation, and � indicators of wetland hydrology in each basin. The site visit portion of the wetland delineation was completed on October 2, 2007. � SER personnel examined the subject property for areas meeting jurisdictional wetland criteria during the site visit and delineated the edge of one basin as being jurisdictional wetland(Figure 5). Detailed soils, vegetation and hydrology data for this wetland is provided in the data sheets of The Technical � Documentation Section. A set of full-scale figures is given in the figures section. RECOMMENDATIONS ' Activities which impact or potentially impact wetlands are currently regulated at several levels of � government. In Minnesota, the two primary jurisdictions are covered at the state and federal levels by the provisions of the following legislative actions. � ➢ State jurisdiction by the Wetland ConservaCion Act of 1991 (WCAj administered by the WCA Local Governmental Unit (LGU). � ➢ Federal jurisdiction by the Clean Water Act of 1972 and subsequent amendments. Wetland protection is implemented by the Corps of Engineers (Corps) with permit certification issued by the Environmental Protection Agency. � While the wetland boundary that SER has delineated is not official until approved by a WCA approved local government unit(LGU), SER advises the properry owner/developer to refrain from � any tilling, draining, or excavating, or any impact to the area SER has delineated as wetland. No grading or filling in wetland basins should commence until all necessary permits have been obtained. Violation of wetland regulations has resulted in substantial civil and criminal penalties. Local � ordinances may regulate wetland modifications such as brush and tree removal and burning in addition to grading and filling. Depending on the location of the property, buffers around the � wetland may also be protected. Any activities in the proximity of the wetland should be cleared with appropriate WCA regulatory agencies. It is also advisable to have the wetland boundary surveyed by a licensed land surveyor. Since the lath used along the boundary can be vandalized or inadvertently � knacked over, a survey of the lath will assure the permanence of the boundary. The client should also be aware that approved wetland bo�indaries are typically valid for only three years from the date of approval. � To avoid project delays associated with wetland regulations,it is essential that you acquire necessary permits from all jurisdictional agencies before initiating activities. A WCA Sequencing form, a � WCA and Army Corps of Engineers Replacement Plan Application form, and a DNR permit � Svoboda Ecological Resources 744 Brown Road North Project No.: 2007-081-03 g Ted Schultze ' 1 Iapplication are among the materials that you may be required Co submit if impacts are proposed for the delineated wetlands. By initiating the permit process as soon as possible,potential costly delays Ito the project may be avoided. � CERTIFICATION � Ben Carlson and Brian Bur ner com leted the above-described delineation on Octol�er 2,2007.This g P � delineation was performed according to the procedures described by the US Army Corps of Engineers in the 1987 Wetlands Delineation Manual and the 2007 Midwest Region Supplement Wetland Delineation Manual.

RANGE IN CHARACTERISTICS: The organic layers are more than S l inches thick. The orgamc material is primarily herbaceous fibers. Some pedons contain up to 15 percent by volume � of woody fragments that cannot be crushed between the fingers. Layers within the control sections rypically have pH of 6.0 to 7.0 in water, but range from pH 5.6 to 7.3. In some pedons, carbonates are in subhorizons of the subsurface tier. In some pedons thin layers contain as much 1 as 20 percent mineral material. Layers within subsurface and bottom tiers have hue of SYR, 7.SYR, or lOYR; value of 2 to 4, and chroma of ] to 4. Typically, the layers in the surface tier are predominantly sapric material,but in some pedons they are primarily hemic material. These � layers are commonly massive, but in some pedons they have weak coarse subangular blocky or weak platy structure. The layers in the subsurface and bottom tiers are predominantly hemic material. In some pedons, layers of sapric materials are within the subsurface and bottom tiers � but total thickness is less than l0 inches. The layers in the subsurface and bottom tiers commonly have weak platy structure or they are massive. COMPETING SERIES: These are the Cutcomh and McMurrav series and the Carbondale, � Carlisle, Care�n, Grecnwc�c�cl, Hou�?hton, Lena, Loxlc , Lupton, Rifle, Spalding, and Taeoosh series. The Cutcomb series that was established in 1995 should be dropped and combined with Boots. McMurray soils consist mainly of woody fibers. Carbondale, Greenwood, Loxley, Lupton, � Rifle, Spalding, and Tacoosh soils are frigid. In addition, Carbondale, Loxley, and Lupton soils 1 Svoboda Ecological Resources 744 Brown Road North Project No.: 2007-081-03 ]'] Ted Schultze � � � have sapric material dominant in the control section and Tacoosh soils have mineral substrata at depChs ranging from 16 to about 50 inches. Carlisle, Houghton, and Lena soils have sapric � material dominant in the control section. ln addition, Lena soils are calcareous throughout. Caron soils have limnic substrata at depths ranging from 16 to about 50 inches. � GEOGRAPHIC SETTING: Boots soils are in depressions within moraines, outwash areas, and lake basins. Slopes are less than 2 percent. Mean annual precipitation ranges from 28 to 33 inches. Mean annual air temperature is estimated to range from 45 to 54 degrees F. � GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing H��u��hton soils and the Adrian and I'alms soils. These soils occupy similar positions on the landscape. Adrian and Palms soils consist of sapric material above mineral substrata which is at depths of less than 50 � inches. Very poorly drained, poorly drained, or somewhat poorly drained mineral soils are commonly along the outer boundary. DRAINAGE AND PERMEABILITY: Very poorly drained. The potential for surface runoff is � negligible. Permeability is moderate or moderately rapid. These soils have an apparent seasonal high water table from 1 foot above the surface to l foot below for long periods in most years. USE AND VEGETATION: These soils are primarily in woodland, but in some places the � vegetation is chiefly reeds, sedges, and cattails. Principal woodland vegetation is tamarack, dogwood, poison sumac, alder, and willow with ground cover of sphagnum moss, marsh grasses, sedges, reeds, and cattails. Ground cover varies with amount of sunlight and microrelief. , DISTRIBUTION AND EXTENT: South-central part of Wisconsin, northern Iowa, southern Minnesota, southern Michigan, and New York. The series is moderately extensive. MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota , SERIES ESTABLISHED: Columbia County, Wisconsin, 1972. REMARKS: It is believed that the depressional positions, which these soils occupy, are frost � pockets with a slightly cooler microclimate than adjacent uplands. Diagnostic horizons and features recognized in this pedon are: Organic material has 12 percent or more organic carbon and is dominatly hemic in the subsurface � tier (12 to 36 inches). The fiber content meets neither the rubbed fiber content or sodium pyrophosphate solubility requirements for either fibric or sapric materials.

The Minnesota State Wetland Conservation Act Rules,Chapter 8420, � further clarifies that"...wetlands must: (1)have a predominance of hydric soils;(2)be inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support a prevalence of hydrophytic vegetation typically adapted for life in saturated soil conditions; and(3) ' under normal circumstances, support a prevalence of hydrophytic vegetation." The I 9$7 U.S. Army Corps of Engineers Manual in Part II,item 24. states that, "The interaction of hydrology,vegetation, and soil results in the development of characteristics unique to wetlands. Therefore, the following � technical guidelines for wetlands are based on the three parameters, and diagnostic environmental characteristics used in applying the technical guideline are represented by various indicatars of these parameters." It is this premise by which SER ecologists has, in their professional judgment, � delineated the wetlands on the subject parcel described in this report. , Wetland Hydrology The most important wetland criterion is hydrology.The presence and persistence of water influences the vegetation types and changes soil morphology. Hydrology may be observed as standing water , (inundation),or may be observed as freestanding water within the soil pit ar auger hole(saturation) usually within Che upper ]2 inches. This is what would be considered primary hydrology indicators. Only one primary indicator is necessary to make the determination that wetland hydrology indeed � exists. The 1987 Corps Manual also has a range of hydrologic zones established based on period of inundation or saturation. These zones and the periods of inundation or saturation for each can be observed in Table 1 below. � Exce ted from the 1987 Manual,H drolo 'c Zones—Nontidal Areas Zone Name Duration Comments WeCland or Not � I Permanently Inundated 100% Inundation>6.6 ft. mean Not(Aquatic Habitat Zone,or Deep Water water de th Habitat) Semipermanently To Nearly Inundation detined as II Permanently Inundated Or �75 <_6.6 feet mean wate�r Wetland � Saturated <100%o de th I[I Regularly Inundated Or �25-75% Wetland Saturated � IV Seasonally Inundated Or <12.5- Wetland Saturated 25% Irre ularl Inundated or Many areas having these Wetland �f h dro h tic ve and h dric V g y >5-12.5% hydrologic characteristics � y p y �' y ' Saturated soils also present are not wetlands Intermittently Or Never Areas with these VI Inundated Or Saturated <5% hydrologic characteristics Not � are not wetlands � Svoboda Ecological Resources 744 Brown Road North Project No.:2007-081-03 2'] Ted Sehultze ' , � The definition of appropriate hydrology according to the l 987 Manual includes two important terms that must be clarified. First, the definition of a growing season is needed. The growing season is � defined in the 1987 Manual as: "...the portion of the year when soil temperature (measured 19.7 inches below the surface) is above biological zero (5° C or 41° F)." According to the 1987 Manual , this period of time can be approximated by using the "starting and ending dates for the growing season based on a 28° F air temperature threshold at a frequency of 5 years in 10." Based on this defimtion the growing season ranges approximately 160 days to 180 days in the Minneapolis/SC. Paul � metropolitan area (160 in the northern suburbs and greater to the south). Therefore, the required inundation or saturation to the surface for 5% of the growing season would be 8 or 9 consecutive days that ground water would need to be at the surface or saturated to the surtace. � The second term in the appropriate hydrology definition from the above paragraph to be clarified is "in most years". This means in 5 of 10 years hydrology must exist within a"jurisdictional wetland" ' for the 8 or 9 consecutive days of the growing season. This means that one observation date or even one whole year worth of detailed hydrology data may be deemed insufficient to determine if appropriate hydrology exists at a given location. In the event that precipitation events accumulate to � above or below normal during just prior to a site visit or during a more intensive hydrology study,the data may be confounded by non-normal circumstances and may be considered outside the bounds of "most years". Ideally, both antecedent soil moist�ire conditions and precipitation would be normal � during all delineations. However, this is not a realisCic impression of climate. Therefore, primary indicators of hydrology must be reviewed with scrutiny prior to determining if hydrology indeed exists. � Wetland hydrology may be observed as standing water (inundation), or may be observed as freestanding water within a soil pit ar auger hole (saturation) usually within the upper 12 inches. , This is what would be considered primary hydrology indicators. Examination of this indicator requires digging a soil pit to a depth of 16 inches and observing the level at which water stands after � sufficient time has been allowed for water to drain into the hole. The required time will vary depending on soil texture. This level represents the depth to the water table; the depth to saturated soils will always be nearer the surface due to the capillary fringe. According to the Hydrology � criteria in the 1987 Delineation Manual,for soil saturation to impact vegetation,it must occur within a major portion of the root zone, typically within ]2 inches of the surface. Only one primary indicator is necessary to make the determination that wetland hydrology is present. However,since a � single observation is not enough evidence, based on the percentage of the growing season this inundation or saturation is required,these data are only valid when reviewed while also considering the abundance of recent precipitation events or the seasonal trend of climate when the site visit was � made(this may be done through review of precipitation records where available). In addition to the primary indicators of wetland hydrology,there are secondary indicators(e.g.oxidized root channels, water-stained leaves, local soil survey data, FAC-Neutral test), of which two must be present to � consider the sample point as having wetland hydrology. � � Svoboda Ecological Resources 744 Brown Road North Project No.:2007-081-03 28 Ted Schultze 1 � � Hydrophytic Vegetation (Wetland Vegetation) Wetland vegetation is defined in the 1987 Manual as "The sum total of macrophytic plant life � growing in water ar on a substrate that is at least periodically deficient in oxygen as a result of excessive water content. When hydrophytic vegetation comprises a communiry where indicators of � hydric soils and wetland hydrology also occur, the area has wetland vegetation." In more standard terms, some plants are more adapted to growing within inundated or saturated soil. Based on literature records and professional experience, a panel of experts compiled a list of plant species and ' assigned each a hydrophytic status(described below and includes five major classes oti probability of a plant occurring within a wetland). � ln terms of delineation there is a gradient of plant species that are adapted to"growing in water or on substrate that is at least periodically deficient of oxygen". Fieldwork associated with wetland delineations includes a procedure (the 50/20 Rule, for determination of dominance), which is also � outlined in the 1987 Manual, by which to determine if hydrophytic plant species dominate the vegetation at a given location. This procedure has been used for the wetland delineation at the subject parcel of this report. ' Hydric Soil Defined in the 1987 Manual as "A soil that is saturated, flooded, or ponded long enough during the � growing season to develop anaerobic conditions that favor the growth and regeneration of hydrophytic vegetation. Hydric soils that occur in areas having positive indicators of hydrophytic vegetation and wetland hydrology are wetland soils." � For the u oses of delineation of wetlands soils cannot be viewed without di in its or extractin P rP , g� �P � � soil using an auger. Therefore, transects of soil samples are taken from perceived upland to perceived wetlands along a transitional boundary. There are specific color indicators,textures, and depth requirements in the soil that are reviewed in order to determine whether hydric soils oceur at a � given point or not. After a transect of soil samples has been taken, upon consideration of vegetaCion and indicators of appropriate hydrology a working prototype for the given wetland is dev�loped by the delineator. The wetland delineator then uses this working prototype to complete the locatian of � the remainder of the wetland boundary,unless the wetland is large enough or the landscape features (vegetation or topography) change enough to warrant additiona] transect samples. � 1 ' 1 ' Svoboda Ecological Resources 744 Brown Road North Project No.: 2007-081-03 29 Ted Schultze ' ' ' ' APPENDIX A ' Explanation of Cowardin and Circular 39 Wetland Classification Systems ' � , � ' 1 , ' ' ' ' ' ' � Svoboda Ecological Resources 744 Brown Road North Project No.: 2007-081-03 30 Ted Schultze ' ' ' . . . . .

Svoboda Svoboda Ecological Resources � 2477 Shadywood Road, Suite 100 Excelsiar, MN 55331 (952) 471-1100 � franks@gpsinnovations.com Introduction � The National Wetland Inventory(NWI)mapping process completed in Minnesota between �1979 and 1982 developed a wetlands inventory map for the state of Minnesota utilizing remotely sensed color � infrared photography that was visually interpreted. The interpretation process hierarchically classified wetlands using, at the time, the recently published Cowardin classification system (Cowardin et al 1979). The wetland interpretation and classification process was ground verified � using selective plots and locations but was field verified to only a limited extent. Consequently,the published NWI paper copies carry the disclaimer that these maps are to be used for advisory purposes only and actual classifications are to be based on ground verification. Visual interpretation � from remote sensed imagery has some limitations particularly with regard to the water regime modifier. Year to year variation in precipitation cycles along with the occurrence of precipitation � events at the time that the imagery was acquired, even if all acqliisition occurred during the spring season, can result in variations in modifier categorization. � Accurate classification becomes critical when regulatory decisions are being made with regard to the wetland type and the amount of de minimum fill that is permissible. Alsc�, it is a matter of scientifically accurate consistency with regard to adherence to the various technical publications and � regulatory guidance documents. Circular 39 was authored by Shaw and Fredine and published by the U.S. Fish and Wildlife Service , (USFWS)in 1956. The intended purpose of Circular 39 was an effort at classifying and inventorying wetlands on a national scale in order to assess the wetland base and related waterfowl production potential. The classification process was never intended to serve as a classification system for � wetland regulatory purposes. However, since it was the first national effort of its kind and as wetland regulatory intentions materialized, this was the only method available to differentiate between wetlands of different types. ' � Svoboda Ecolotrical Resources 744 Brown Road I�1orth Project No.: 2007-081-03 3� 'Ced Sehultze , 1 � The Board of Water and Soil Resources(BWSR)cross-reference table(8420.0549 subp.2.)indicates that Circular 39 Type 3 wetlands have a "C" water regime modifier. This is an inaccurate cross- � reference and the intent of this technical paper is a clarification of the correct interpretation.There is also a common tendency to refer to bottomland hardwoods as Type 7 wetlands. This is also an � inaccurate classitication. The NWI paper maps do not use the water regime modifier"E" because it was difficult to interpret � from the inherent limitations imposed by the remote sensed imagery.Therefore,most if not all Type 3 wetlands were given the designation "C". However, the following discussion will examine and clarify the differences between Circular 39 Types l, 1L, 2, 3, and 7 and the appropriate Cowardin � water regime modifying terms. Circular 39 Wetland Types ' Type 1/1L —Seasonally Flooded Basins or Flats Type 1 wetlands are characterized by soil that is covered with water or is waterlogged during variable seasonal periods but is usually well drained during rnuch of the growing season (italics � added for emphasis). These wetlands may be found in upland depressions as well as in overflow bottomlands, i.e. river and stream floodplains. Within floodplains, flooding may occur in late fall, � winter or spring. In upland contexts,basins ar flats may be water filled during heavy rain events or following spring snow melt. Vegetation rypes vary greatly according to the season and the duration of flooding.Included within Type 1 are bottomland hardwoods as well as some herbaceous growths. ' Where the water has receded early in the growing season,smartweeds,fall panicum,tealgrass,chufa. redroot cypress and weeds (such as marsh elder, ragweed and cockleburs) are likely to occur. Shallow basins that are submerged only very temporarily usually develop little or no wetland � vegetation (Shaw and Fredine 1956, p30). Since Circular 39 was developed for national application,the description of Type 1 wetlands covers � a broad range of geographic contexts hence the reference to winter flooding. Cowardin et al (p. 28) in Table 4 describe Type 1 wetlands as seasonally flooded basins or flats,wet � meadow, bottomland hardwoods and shallow freshwater swamps. The water regimes are described as temporarily tlooded (A) or intermittently t7ooded (J). � The Minnesota DepaRment of Natural Resources (D1VR), within the regulatory framework of the ProCected Waters and Public Wetlands framework has added the Type 1L designator to more clearly clarify the Circular 39 classification method and to allow an accurate distinction to be made between , bottomland hardwoods, seasonally flooded non-vegetated or herbaceous vegetated basins and hardwood swamps. The distinction on the basis of hydrology is clear and it was the intent of the � DNR to differentiate between forested bottomland hardwoods and non-forested wetlands. Type 2—Inland Fresh Meadows 1 Inland fresh meadows(Type 2)wetlands have soil that is usually without standing water during most � Svoboda Bcological Resources 74�t Brown Road North Project No.: 2007-081-03 32 Ted Sehultze � � ' � of the growing season but is waterlogged to within at least a few inches of its surface. Vegetation includes grasses,rushes, sedges, and various broad-leaved plants. In northern environments,typical ' species representatives are carex, rushes, redtop, reedgrasses, mannagrasses, prairie cordgrass and mints. Meadows may be present in shallow lake basins, sloughs, farmland "sags" or may border � shallow marshes on the landward side. Table 4(Cowardin et al p. 28)includes within�ts description of Type 2 wetlands as fen and northern � sedge meadow. The water regime is described as saturated (B). This description, as used by some plant ecologists and wetland scientists,is specifically limiting and at least in some instances does not suggest that reed canary grass dominated wetlands would fall into this category. ' Type 3 —Inland Shallow Fresh Marshes Inland shallow fresh marshes (Type 3) wetlands have a soil substrate that is usually waterlogged ' during the growing season and at some times may be covered with as much as 6 inches or more of water. Common vegetation includes grasses,bulrushes, spikerushes, and various other marsh plants such as cattails, arrowheads,pickerelweed, and smartweeds. Common representatives in the North � include reed, whitetop,rice cutgrass,carex and giant burreed.Type 3 marshes may nearly till shallow lake basins or sloughs or may border deep marshes on the landward side. They may also occur as seep areas in agricultural fields resulting from failing drain tile systems or where sand seams are near � the sur�ace on hillside slopes. Cowardin et al (Table 4, pg 28) describes the water regime as either seasonally flooded (C j or � semipermanently flooded(F). The accurate categorization of Type 3 wetlands is most critical since seasonally flooded wetlands containing reed canary grass are eligible for larger de minimus fills (up � to 10,000 square feet) than cattail marshes (only 400 square feet). The difference in hydrological regimes is discussed in the next section. ' Type 7—Wooded Swamps Wooded swamps (Type 7)wetlands have a soil substrate that is"waterlogged to within a few inches of its surface" (Shaw and Fredine 1956, pg 22)during the growing season and often can be covered ' with as much as 1 foot of water.Type 7 wetlands often occur along the edges of sluggish streams,on floodplains, on flat uplands and in very shallow lake basins. In the North, trees include tamarack, arbor vitae, black spruce,balsam, red maple, and black ash. Northern evergreen swamps frequently , have a thick ground cover of mosses. Deciduous swamps frequently contain beds of duckweeds, smartweeds and other herbaceous plant species. Hardwood swamps frequently are associated with Type 6, shrub swamp wetlands. � Table 4 (Cowardin et al 1979, pg 28) states that Type 7 wetlands include all water regimes except permanently flooded.This description is inconsistent with the more specific description of Shaw and � Fredine(1956)that describes a Type 7 wetland as having waterlogged soil to within a few inches of the surface throughout the growing season. � Wooded swamps (Type 7) are frequently mischaracterized as bottomland hardwoods (Type 1 Lj, � Svoboda Ecological Resources 744 Brown Road North Project No.: 2007-081-03 33 Ted Sehultze � ' � however there are significant differences in the hydrological regimes between the two.The nature of these differences is discussed in a subsequent section. � Cowardin Water Regime Modifiers � The purpose of water regime modifiers is to provide a better description of the variations in hydrology that occur in wetlands on a seasonal and annual basis. These descriptions are general in nature because wetland hydrology is extraordinarily dynamic. Hydrology is the most variable � component of wetlands and can vary substantially within a single basin weekly,monthly,seasonally, annually and over decades. Extraordinarily wet or dry periods, whether shart or prolonged, do have dramatic effects on the presence or absence of water in any given wetland. Whether a wetland has � naturally occurring hydrology or whether it is partially or completely drained affects its behavi�r as a component of the landscape,its appearance, the vegetation that inhabits it, and the effectiveness of the functions that it performs. Wetlands may also have artificially induced hydrology due to � stormwater inputs or interconnections to other wetlands via ditch or tile drain systems. Careful consideration of each wetland within the overall context of the landscape is necessary to understand which water regime best fits along with the special modifiers that describe alterations to wetlands. ' One s ecial modifier class that is missin is the "stormwater ond" cate or . This is a commonl P � P g Y Y ' occurring condition in urban landscapes and should be added. Stormwater ponds may have been specifically constructed for that purpose or, in the past, previously existing wetlands were used to treat stormwater and now function as stormwater ponds rather than "natural" wetlands. � Descriptions of the modifiers are taken from Cowardin et al (1979,pgs 21—22)and from Santos and Gauster(1993, pgs 30—32). � Descriptions within the parentheses are terms used on the NWI key and the longer description is the one used by Cowardin et aL (1979). Where a parenthetical term is excluded, the two terms are the � same. Modifier "A" , Temporarily Flooded (Temporary� Surface water is present for brief periods during the growing season but the water table usually is well below the soil surface for most of the season.Temporarily flooded wetlands usually have plants � that are characteristic of both uplands and wetlands.This modifier description is most appropriately assigned to Type ] and 1 L wetlands but clearly does not fit the Type 7 Hardwood Swamp wetland type. Table 4 (Cowardin et al ]979, pg 28) is inconsistent by including this regime in the Type 7 ' category. I Modi�er"B" Saturated Soil saturation occurs to the surface for extended periods during the growing season but surface � water is seldom present or evident. Many sedge and rush wetlands tit into this category. This � Svoboda Ecological Resources 74a Brown Road North Project No.: 2007-081-03 �q Ted Sehultze � ' 1 modifier also aptly fits the water regime that occurs in the hardwood swam s that are resent in arts P P P of Minnesota in hardwood swamps such as black ash swamps and in coniferous swamps such as � white cedar, tamarack, and black spruce swamps. This modifier also describes Type 2 wetlands as described above and includes fens and sedge/rush dominated wetlands. ' Modifier��C" Seasonally Flooded (Seasonal) , Surface water is present for extended periods especially early in the growing season but is absent by the end of the season in most years. When surface water is absent, the water table is often near the surface. Santos and Gauster (1993, pg 31) add that the water table, after flooding ceases, is very � variable,extending from saturated to a water table well below the surface.This accurately describes the situation that frequently occurs within reed canary grass wetlands where there is saturation to the surface or even several inches of inundation after snow melt. In most years, by the end of May, � surface water is no longer evident in many of these basins. During June,the water table continties to recede until by August, the water table may be two or more feet below the surface. Many of these areas are used for livestock pasturing and for harvesting meadow hay.Wetlands with a"C"modifier , that consist predominantly of reed canary grass should be categorized as either Type 1 or Type 2 depending on the length of time that water is present. This modifier is the most difficult to specifically assign to a Type l, Type 2 or Type 3 category as it could apply to any of the three. � Modifier "D" Seasonal Well-Drained(No comparable Cowardin category� � Santos and Gauster(1993,pg 3l) describe this modifier as applying where surface water is present for extended periods especially early in the growing season. The water table, after t7ooding ceases ' falls well below the ground surface. This modifier would appear to apply to tloodplains and bottomland hardwood forests(Type 1 L)as described above.Modifiers"C"and"D"seem to overlap to a certain extent and could also apply to reed canary grass wetlands as well. ' Modifier "E" Seasonal Saturated (No comparable Cowardin cate�ory� � Surface water is present for extended periods especially early in the growing season, and remains saturated near the surface for most of the growing season (Santos and Gauster 1993, pg 3l). This modifier would appear to apply to fens, sedge and rush meadows, some Type 6 shrub swamps,Type � 7 Hardwood Swamps and Type 8 bogs. Some reed canary grass wetlands might fall into this category but most seem to be dried out by early to mid-summer. ' Modifier "F"' Semipermanently Flooded (Semipermanent) Surface water persists throughout the growing season in most years. When surface water is absent, � the water table is usually at or very near the land surface (Cowardin et al 1979, pg 22; Santos and Gauster 1993, pg 31). This modifier applies to Type 3 cattail marshes and may also apply to some hardwood swamps such as black ash, conifer bogs and Type 6 alder shrub swamps. ' � Svoboda Ecological Resources 744 Brown 12aad I�1orth Project No.: 2007-081-03 35 Ted Schultze � ' , Modifier "G" Intermittently Exposed ' Surface water is present throughout the year except in years of extreme drought (Cowardin et al l 979, pg 22; Santos and Gauster 1993, pg 3]). Type 4 wetlands fall into this category. � Modifier "H" Permanently Flooded (Permanent) Water covers the land surface throughout the year in all years. Vegetation is composed of obligate � hydrophytes (Cowardin et al 1979, pg 22). I Modifier"J" Intermittentiv Flooded The substrate is usually exposed,but surface water is present for variable periods without detectable ' seasonal periodicity. Weeks, months, or years may intervene between periods of inundation. The dominant plant communities may change as soil moisture conditions change. According to Cowardin et al (1979, pg 22) "Some areas exhibiting this regime do not fall within our definition of wetland � becaLise they do not have hydric soils or support hydrophytes." Some of the areas in agricultural fields that have been flooded during the sprin� and early summer of 2003 and 2004, following periods of intense and persistent rainfall, may well fall into this category and may not in fact be � subject to regulation as a wetland. Modifier"K" � Artificially Flooded (Artificial) The amount and duration of flooding is controlled by means of pumps or siphons in combination � with dikes or dams. Water and wastewater treatment facilities are included under this category.This definition does not appear to include stormwater ponds.

One of the criteria for a jurisdictional wetland is the presence of hydrophytic vegetation (1987 Manual pp 16 - 26). Type 1 wetlands often are found in agricultural fields and often are determined to be jurisdictional on the � basis of an aerial 35mm slide review; the quality of the slides is poor under the very best of circumstances. .The determination of regulatory jurisdiction is based on normal circumstances or as defined by the COE, being agriculturally cropped 51 out of 100 years (i.e. by inference lacking � sufficient hydrology for either 5 or 12.5 percent of the growing season). The Wetland Conservation Act(WCA)determines narmalcy as a�ricultural cropping for 6 out of 10 � years (MnRules 8420.0110, Subp 53; 8420.0122 Subp.l, A and B j. Typically, normalcy on agricultural lands is determined by the review of the aforementioned low quality 35mm aerial slides and judgments are made as to whether an area is cropped or if the crops are subject to hydrological � stresses. The process is highly subjective and can be biased by excessive precipitation that may occur early in the crop growth cycle. � Field examination of these areas may indicate the presence of smartweed and some of th� other indicated species in seasonally abnormally wet years whereas in normal years, hydrophytic � vegetation is absent. It is highly probable that the process of determination of Type 1 wetlands as jurisdictional in many cases is extending beyond the legitimate detinition of Type 1 wetlands and the intent of the 1987 Manual. Does a Type 1 basin need to be flooded for 5 percent of the growing � season (the lower definitional bound for jurisdictional hydrology) or 12.5 pereent (the upper definitional bound for jurisdictional hydrology)in order for hydrophytic vegetation to develop?In practice, the St. Paul District of the Corps of Engineers (COE) (also applied in praetice under the � Wetland Conservation Act) applies the 5 percent hydrological definition but if that is too short to allow the development of hydrophytic vegetation under normal conditions than the absence of hydrophytic vegetation would make those Type ] wetlands non-jurisdictional. � Type 1L— bottomland hardwoods — poses an equally difficult regulatory question. Tools for the evaluation of hydrology for non-cropped areas are much more data intensive and are also subject to � precipitation event variability.Measurement tools for the determination of precipitation normalcy are a combination of evaluating annual precipitation and comparison to a 30-year rolling average along with extensive near ground surface early season hydrological monitoring. If the water levels are � within 12"of the surface for less than 8.5 days in the general latitude of the Twin Cities(5 percent of the growing seasonj, than the area is not wetland. If water levels are within l2" of the surface � between 5 percent and ]2.5 percent of the growing season (21 days in the general ]atitude of the Twin Cities) according to the 1987 Manual (Table 5 pg. 36), the area may be wetland but usually is � Svoboda Ecological Resources 744 Brown Road North Project No.: 2007-081-03 37 Ted Schultze � ' � not. However, the standard practice of the St. Paul COE is to declare an areas that exceed the 5 Y percent criteria to be judged jurisdictional wetlands. Areas with water levels within 12" of the ' surface in excess of 12.5 percent of the growing season are wetlands. � No one has ever undertaken a scientific study to evaluate the relationship between the hydrological requirements and the presence of various wetland or non-wetland plant species.This is a critical,yet unanswered question. Some studies have been completed examining soil types and hydrological , responsiveness but the link between plants and hydrology has yet to be made. Given the annual cost of jurisdictional decisions in terms of "lost land" opportunities, perhaps such a study would be prudent. � The implications of regulatary misinterpretation are enormous in that it is likely that hundreds of acres of Type l wetlands are avoided or mitigated for each year when legitimately these areas are ' non-jurisdictional and could be developed. Avoidance or impact and mitigation can cost developers and ultimately, homebuyers, millions of � dollars annually just in the developing seven-county Metropolitan Area. Mitigating a non- jurisdictional Type l wetland impact at a 2:1 ratio reduces the usable land base unnecessarily. For every 50 acres of non-jurisdictional impact, 100 acres are removed from the land supply. At an � average cost of $]00,000 per acre, the cost to developers and ultimately to homeowners is $10,000,000 in just one year for just _50 acres. � Type 2/3 Type 3 wetlands create the greatest classification difficulty from the perspective of de mi�airr�us � qualification. A Type 3 wetland that is seasonally flooded (C) is typically characterized by reed canary grass whereas a Type 3 semi-permanently flooded wetland is more likely characterized by a growth of cattails. The reed canary wetlands are�enerally dry by late spring to early summer. By late � summer, the water tables have receded to well below the surface (> 18 — 36"). In contrast, Type 3 cattail wetlands still contain water above or very near the surtace during normal growing seasons. � The WCA permits the use of de minimus filling of Types 1, 2, 6 and 7 wetlands. Clearly it is not the intent of the WCA to allow the application of the de rrl�nimus criteria to fens since the WCA specifically addresses fens as a special category for protection. Therefore, the Type 2 designation � must apply to the"C": modifier Type 3 wetland. Further, Type 3 wetlands in excess of 2.5 acres in incorporated areas and in excess of 10 acres in unincorporated areas are protected under the DNR protected waters statute. In the DNR wetland inventory and classification process, the Type 3 � wetlands were clearly dominated by cattails hence the inference that reed canary grass wetlands were Type 2. , Type 7/Type 1L Inconsistencies in technical descriptions regarding the hydrological regime of these two wetland rypes from a scientific perspective become only a matter of discussion between scientists. However, � when wetland types are applied from a regulatory perspective,accuracy in detinition becomes crucial � Svoboda Ecological Resources 744 Brown Road North Project No.: 2007-081-03 38 1ed Schultze ' ' � because certain activities may be permitted in one wetland type and prohibited in another. At present, Wetland Types 1 L and 7 are subject to the same wetland regulatory requirements and exceptions. 1 However, that may not be always the case and therefore it is important to note the crucial yet subtle differences between the two types. � The majority of bottomland floodplain forests in many years have water tables several feet beneath the soil surface. The language "throughout the growing season" is quite specific in Circular 39. A � careful consideration of the species described in the listing provided by Shaw and Fredine (1956) indicates that the habitat requirements of the species listed include the typical presence of a near surface high water table whereas the description of a Type iL forested wetland describes the term � "bottomland hardwood", a rather vague non-specific term but tree species generally included in Chis category are elm,cottonwood,green ash,and silver maple.Bottomland hardwoods do not include the species described as associated with hardwood swamps. � Type 7 wetlands are persistently wet under all but the driest conditions whereas Type l/1 L wetlands are generally dry except under the wettest of conditions. The distinction is significant. � In general, the Board of Water and Soil Resources cross-reference classification (Mn Rules 8420.0549 subp. 2.) are generally accurate but the designation of PEMC as a Type 3 wetland poses � some problems. Where the Type 3 wetland is comprised of cattails, a de minimus exemption of 400 square feet applies but where the wetland is reed canary grass, also a Type 3 designation should technically apply based on the above discussion. The reed canary grass wetlands do not fit well into � the"C" modifier category nor do they fit into the "B": modifier either. ' As a matter of standard practice,it would seem best to designate reed canary grass wetlands as Type 2 wetlands regardless if the modifier is "B"of"C".The difference is important in that a de mi,zirnus exemption of anywhere from 2000 square feet to 10,000 square feet might be applicable.Also being � accurate with regard to wetland type is important when designation of the regulatory wetland type is done based on if the deepest part of the basin or the dominant vegetation is the wetland type that determines allowable fill. This requirement often over-regulates the reed canary grass fringe and � eliminates the possibility of applying the 2000to l 0,000 square foot de rniraimus in many cases where a very small percentage of the overall basin is cattail but because the deepest part of the basin criteria is applied, only 400 square feet of de minimus fill may be used. � In general, while this may seem to be an arcane discussion, in reality it is cr�icial in order for the regulated community to rightfully claim the wetland exemptions that the law permits.Conversely,it � entitles the landowner to rightfully claim useable land for development purposes. A clear understanding and accurate interpretation of the classification system is necessary in order for the exemptions available under the de �nini�nus categories to be appropriaCely applied.
