The study parcel is located in the city of Orono, MN in Hennepin County (Figure 1). Three wetland boundaries were delineated at this site. Six sample transects were established along the boundaries in order to characterize the soil, vegetation, and existing hydrology within the wetland-to-upland transition zone. INTRODUCTION The subject parcel is approximately 6.1 acres and is dominated by graminoids and early successional woody vegetation. The topography of the site is at its highest elevation in the northeast corner of the property, with low lying areas in the far western and southern reaches. The surrounding land use is primarily residential. The identified wetlands were classified according to the Cowardin et al., the Circular 39 and the Eggers and Reed classification systems and marked with pink "Wetland Delineation" pin flags. The wetland boundaries were surveyed by Gronberg and Associates. The Technical Documents section of this report contains field data sheets, plant indicator status information, soil survey information, and wetland defmition information. 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 2010 Midwest Regional 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 Documents 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, geology, soils, hydrology plant and animal communities, and other factors are important to the identification and functioning of wetlands. These differences cannot be Svoboda Ecological Resources 4115 Watertown Road Project Number: 2012-001 1 Orono MN 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), Web Soil Survey of Hennepin County map (Figure 3), Minnesota Public Waters Inventory maps (Figure 4), and 2010 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 used 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 consist of a representative upland sample point and representative wetland sample point. Information obtained at the sample points can be found on the field data sheets located in the Technical Documents section. Wetland boundaries were marked at the site by pink "Wetland Delineation" pin flags. 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 above were lacking in one or more of these criteria. Wetlands were classified in accordance with 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 and Eggers and Reed classification systems are also given. The indicator status of plants, as described in the Technical Documents section, was determined using the National List of Plant Species That Occur in Wetlands — Region 3 (Sabine 1999). RESULTS The National Wetland Inventory indicates the presence of two wetlands within the study area (Figure 2). The first is classified PEMC,the second PEMCd. The Web Soil Survey of Hennepin County(Figure 3) identifies five soil map units present on the subject property. They are as follows: Hamel — overwash Hamel complex, Lester — Kilkenny complex, Angus — Kilkenny complex, Klossner soils, and Blue Earth & Houghton soils. Of these, the Klossner and Blue Earth & Houghton soils are considered all hydric. The remainder are classified as partially hydric. Soil series descriptions are provided in the Technical Documents section. Svoboda Ecological Resources 4115 Watertown Road Project Number: 2012-001 2 Orono MN The Minnesota Department of Natural Resources, State Protected Waters Map (Public Water Inventory) indicates no public waters within the study area(Figure 4). Site Visit SER ecologists examined the subject property for areas meeting jurisdictional wetland criteria during the site visit. Three areas meeting the jurisdictional criteria of a wetland were flagged, and boundaries were determined and delineated. The approximate wetland boundary is outlined in yellow(Figure 5). Wetland 1 is a Type 2, PEMB, Fresh Wet Meadow. The vegetation at this site was a monoculture of reed canary grass (Phalaris arundinacea, FACW). The transition to upland is marked by a distinct shift in plant communities, with common buckthorn (Rhamnus cathartica, FAC) and tatarian honeysuckle (Lonicera tatarica, FACU) dominant in the shrub layer and Kentucky bluegrass(Poa pratensis, FAC)dominant in the herb layer. Wetland 2 is a Type 2, PEMB, Sedge Meadow. Cottonwood (Populus deltoides, FAC) was present in the canopy layer with a dense layer of tussock sedge (Carex stricta, OBL) and reed canary grass below in the herb layer. The upland vegetation is characterized by American elm (Ulmus americana, FACW) in the canopy with common buckthorn dominant in the shrub and herb layers. Wetland 3 is a Type IL, PFO 1 A, Lowland Hardwood Forest. This sample point had a thick canopy layer consisting of American elm, green ash(Fraxinus pennsylvanica, FACW) and black willow (Salix nigra, OBL). Once again reed canary grass was dominant in the herb layer. The upland vegetation was characterized by an increased density of common buckthorn. The soils at sample point 1-1 UP consisted of 20 inches of 10yr 2/1 clay loam with another 8 inches of 2.5y 6/2 clay matrix (95%) with 5% 7.5yr 4/6 matrix concentrations. Hydric indicator Al2 (Thick Dark Surface) was present. At sample point 1-1 WET there was 24 inches of 10yr 2/1 clay loam. From 24 to 28 inches was 2.5y 6/2 clay matrix (95%) with 5% 7.5yr 4/6 matrix concentrations. Hydric indicator Al2 was present at this sample point as well. Soils at sample point 2-1 UP consisted of 20 inches of 10yr 3/2 clay loam. The soils at sample point 2-1 WET consisted of 30 inches of 10yr 2/1 silt loam, then 6 inches of 2.5y 6/2 clay matrix (95%)with 5% 7.5yr 4/6 matrix concentrations. Hydric indicator Al2 was present. Soils at sample point 3-1 UP consisted of 18 inches of 10yr 2/1 clay loam. From 18 to 24 inches was 10yr 4/1 clay loam, and from 24 to 28 inches was 2.5y 6/2 clay loam matrix with 5% 7.5yr 4/6 matrix concentrations. Hydric indicator Al2 was present. Soils at sample point 3-1 WET consisted of 30 inches of 10yr 2/1 silt loam. From 30 to 36 inches was 2.5y 6/2 clay matrix (95%)with 5% 7.5yr 4/6 matrix concentrations. Hydric indicator Al2 was present. Wetland hydrology was observed at all wetland sample points. At point 1-1 WET indicators A2 (High Water Table), A3 (Saturation), D2 (Geomorphic Position), and D5 (FAC-Neutral Test) Svoboda Ecological Resources 4115 Watertown Road Project Number: 2012-001 3 Orono MN were found. The same set of indicators were found at points 2-1 WET and 3-1 WET. Detailed soils, vegetation, and hydrology data for the delineated jurisdictional wetlands are provided in the data sheets of the Technical Documents section. DISCUSSION 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 4/23/2012. SER personnel examined the subject property for areas meeting jurisdictional wetland criteria during the site visit and delineated the edge of two basins as being jurisdictional wetlands (Figure 5). Detailed soils, vegetation and hydrology data is provided in the data sheets of the Technical Documents section. A set of figures is provided in the Figures section. RECOMMENDATIONS Activities that impact or could potentially impact wetlands are 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 Conservation Act of 1991 (WCA) 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 boundaries that SER has delineated are not official until approved by a WCA approved local government unit (LGU), SER advises the property owner/developer to refrain from any filling, 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 may result 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 pin flags used along the boundary can be vandalized or inadvertently knocked over, a GPS survey of the flags will assure the permanence of the boundary. The client should also be aware that approved wetland boundaries are typically valid for only three years from the date of approval. Svoboda Ecological Resources 4115 Watertown Road Project Number: 2012-001 4 Orono MN 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 application are among the materials that you may be required to submit if impacts are proposed for the delineated wetlands. By initiating the permit process as soon as possible,potential costly delays to the project may be avoided. Svoboda Ecological Resources 4115 Watertown Road Project Number: 2012-001 5 Orono MN CERTIFICATION Frank Svoboda completed the above-described delineation on 4/23/2012. This delineation was performed according to the procedures described by the US Army Corps of Engineers in the 1987 Wetlands Delineation Manual and the 2010 Midwest Region Supplement Wetland Delineation Manual. The delineation meets the standards and a criterion described in these manuals and conforms to the applicable standards and regulations in force at the time the delineation was completed. Report and graphics were prepared by David Haar(Wetland Ecologist UGIS Specialist) on this day 05/09/2012. The wetland delineation was completed initially by Brian Burgner during the winter season based on visible vegetation and verified by a spring field visit by Ben Carlson at which time growing plants were documented and soil samples obtained.. The delineation report was reviewed by Frank Svoboda, President of Svoboda Ecological Resources.

TYPE LOCATION: Wright County, Minnesota; about 1 mile south of Montrose, 200 feet north and 80 feet east of the southwest corner of sec. 1,T. 118 N.,R. 26 W.;USGS Waverly quadrangle; lat. 45 degrees 03 minutes 20 seconds N.; long. 93 degrees 54 minutes 38 seconds W.,NAD27. RANGE IN CHARACTERISTICS: Depth to free calcium carbonates ranges from 24 to 54 inches. Rock fragments of mixed lithology comprise 2 to 8 percent of the volume throughout. Soil saturation occurs in the lower third of the series control section for periods of one month or more. These soils are dry for more than 60 days in the soil moisture control section during the 120 days following the summer solstice. The clay content ranges from 22 to 30 percent and the sand content ranges from 30 to 45 percent throughout. The A or Ap horizon has hue of l OYR, value of 2 or 3 and chroma of 1 to 3. It is typically loam or clay loam,but silt loam, sandy loam and fine sandy loam are within the range. The reaction is moderately acid to neutral. Some pedons have a E horizon with hue of l OYR, value of 4 or 5, and chroma of 1 to 3. It is loam, sandy loam or fine sandy loam. The reaction is moderately acid to neutral. The Bt horizon has hue of l OYR or 2.5Y, value of 4 or 5, and chroma of 3 or 4. It is clay loam, loam, or sandy clay loam. Redoximorphic features are present in the lower part of the Bt horizon in some pedons. The B/A clay ratios range from 1.2 to 1.4 . It is strongly acid to slightly acid in the upper part and moderately acid to neutral in the lower part. A Bk horizon is present in some pedons. The BC horizon has soil color and textures similar to the Bt and C horizon respectively. Clay films are on ped faces or root channels. The reaction is slightly acid to slightly alkaline. The C horizon has hue of 2.5Y or l OYR,value of 4 to 6 and chroma of 3 to 5. It is loam or clay loam. It is slightly alkaline or moderately alkaline. Redox depletions with chroma of 2 or less are in this horizon. COMPETING SERIES: These are the Argyle, Baltimore, Bassett, Blooming, Caleb, Dowagiac, Dunbridge, Gara, Koronis, Lauramie, Lester, Longlois, Lydick, Mohawk, Neda,Newcomer, Oneco, Orwood, Racine, Razort, Sebbo, Taovi, Waucoma, and Winneshiek soils. The Argyle, Baltimore, Blooming, Gara Koronis, Lester, Lydick, Mohawk, Razort and Taopi soils do not have soil saturation in the lower third of the series control section for more than 1 consecutive month. The Bassett, Caleb, Orwood, and Sebbo soils do not have free carbonates above a depth of 48 inches. Dowagiac soils have sandy outwash sediments with less than 10 percent clay in the lower third of the series control section. Dunbridge and Winneshiek soils have sola terminated by limestone bedrock at depths of 20 to 40 inches. Lauramie soils are dry in some parts of the soil moisture control section for less than 60 days during the 120 days following the summer solstice. Longlois soils have 15 to 60 percent rock fragments in the lower half of the series control section.Neda and Racine soils have less than 30 percent sand in the upper one fourth of the series control section.Newcomer, Oneco and Waucoma soils have sola terminated by a lithic contact at depths of 40 to 60 inches. GEOGRAPHIC SETTING: These soils have convex slopes on moraines or till plains. Slopes range from 2 to 5 percent. They formed in calcareous, loamy glacial till of late Wisconsin Age. Mean annual air temperature ranges from 45 to 50 degrees F. Mean annual precipitation ranges from 25 to 32 inches. Frost-free days range from 125 to 165. Elevation above sea level ranges from 700 to 1600 feet. GEOGRAPHICALLY ASSOCIATED SOILS: These includes the Cordova, Dundas, Glencoe, Hamel, Hou ton, Klossner, and Le Sueur soils which formed in similar parent materials. Poorly drained Cordova and Dundas soils are on flats and upper drainageways. Very poorly drained Glencoe soils are in depressions and drainage channels. Poorly drained Hamel soils are on footslopes or toeslopes. Very poorly drained Houghton and Klossner soils are organic and are in depressions. Moderately well drained Le Sueur soils are on slightly elevated flats and less sloping area. DRAINAGE AND PERMEABILITY: Well drained. Permeability is moderate. Runoff is low. A seasonal high apparent water table is at 3.5 to 6 feet during March to June in most years. USE AND VEGETATION: Mostly cropped to corn and soybeans. Native vegetation is mixed prairie grasses and deciduous forest. DISTRIBUTION AND EXTENT: South-central and east-central Minnesota and possibly northeastern Iowa. Moderate extent. MLRA-103. MLRA OFFICE RESPONSIBLE: St. Paul,Minnesota SERIES ESTABLISHED: Meeker County,Minnesota, 1995. REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic subgroup-the zone from the surface to a depth of 8 inches(Ap horizon); argillic horizon -the zone from 8 to 35 inches(Bt horizons); This soil was previously included in the Lester series. However, due to more investigations, it was concluded that Lester soils on a slope of 2 to 5 percent have seasonal high water table between 3.5 and 6 feet rather than 6 feet or greater.

A firm till phase of clay loam with a moist bulk density of 1.6 to 1.9 gm/cc is also recognized. COMPETING SERIES: These are the Moundprairie and Uturin(T) series. These soils do not have coprogenous earth in the series control section. GEOGRAPHIC SETTING: These soils have plane or slightly concave slopes with gradient of 0 to 1 percent. They are in small to large lake basins in glacial moraines, flood plains, and lacustrine plains. These basins formerly had lakes, and most of the lakes were drained since settlement. These sediments are underlain by loamy till or lacustrine sediments of the Late Wisconsin glaciation at depths of 76 cm(2.5 to more than 203 cm. Mean annual temperature is 7 to 11 degrees C (45 to 50 degrees F). Mean annual precipitation is 610 mm to 813 mm(24 to 32 inches). Frost free days range from 155 to 200. Elevations above sea level range from 213 m to 480 m(700 to 1570 feet). GEOGRAPHICALLY ASSOCIATED SOILS: These are other poorly drained and very poorly drained mineral and organic soils within the basin and the Clarion and Lester soils and their respective topographic associates on the adjacent uplands. DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Very poorly drained. Surface runoff is negligible to ponded. The saturated hydraulic conductivity, measured in cm per hour, is .05 to 5.1 (.02 to 2.0 inches)in the upper material and .05 to 1.5 (.02 to .6 inches)in the lower part. Seasonal high saturation ranges from plus 91 to 30 cm(3 to 1 foot) for undrained areas of this soil. Areas that are drained have variable depths to saturation based on the effectiveness of the drainage network. USE AND VEGETATION: Most of this soil is cropped to corn and soybeans. Some is used for pasture or hay. Invasive vegetation(after drainage) is mostly sedges, reeds, and grasses. They lack native vegetation in the conventional sense because these soils were, until recently, sediments in the bottom of lakes. DISTRIBUTION AND EXTENT: MLRA-103. Southern Minnesota and north-central Iowa. Moderately extensive. MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota SERIES ESTABLISHED: Rock County, Minnesota, 1945. REMARKS: Problems remain in the classification of these series because no taxon has been defined in Soil Taxonomy that adequately accommodates soils that have formed entirely in coprogenous earth. Diagnostic horizons and features recognized in this pedon are: Surface horizon that meets requirements of a mollic epipedon except it is underlain by stratified C horizon. A firm till substratum is recognized in the geomorphic surface landform of the Kandiyohi till. In the past some sloping fens were included in the concpet of Blue Earth.

THE TECHNICAL DOCUMENTATION SECTION Wetland Definition WETLAND DEFINITION According to the 1987 U.S. Army Corps of Engineers "Wetlands Delineation Manual" (1987 Manual; the document used by all delineators to define wetlands) a wetland is "Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions." 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 1987 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 indicators 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 or auger hole (saturation) usually within the upper 12 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. Excerpted from the 1987 Manual,H drolo is Zones—Nontidal Areas Zone Name Duration Comments Wetland or Not I Permanently Inundated 100% Inundation>6.6 ft.mean Not(Aquatic Habitat Zone,or Deep Water water depth Habitat Semipermanently To Nearly <75 Inundation defined as II Permanently Inundated Or <100% <_6.6 feet mean water Wetland Saturated depth III Regularly Inundated Or >25-75% Wetland Saturated Seasonally Inundated Or <12.5- N Saturated 25% Wetland Many areas having these V Irregularly Inundated or >5-12.5% hydrologic characteristics Wetland(if hydrophytic veg.and hydric Saturated soils also present are not wetlands Intermittently Or Never ° Areas with these VI Inundated Or Saturated <5% hydrologic characteristics Not are not wetlands A-1 The definition of appropriate hydrology according to the 1987 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 definition the growing season ranges approximately 160 days to 180 days in the Minneapolis/St. 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 surface. 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 moisture conditions and precipitation would be normal during all delineations. However, this is not a realistic 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 or 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 12 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. A-2 Hydrophytic Vegetation (Wetland Vegetation) Wetland vegetation is defined in the 1987 Manual as "The sum total of macrophytic plant life growing in water or on a substrate that is at least periodically deficient in oxygen as a result of excessive water content. When hydrophytic vegetation comprises a community 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 of probability of a plant occurring within a wetland). In 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 purposes of delineation of wetlands, soils cannot be viewed without digging pits or extracting 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 occur at a given point or not. After a transect of soil samples has been taken, upon consideration of vegetation and indicators of appropriate hydrology a working prototype for the given wetland is developed by the delineator. The wetland delineator then uses this working prototype to complete the location of the remainder of the wetland boundary, unless the wetland is large enough or the landscape features (vegetation or topography) change enough to warrant additional transect samples.
