The study parcel is located in Orono MN, Hennepin County (Figure 1). One wetland boundary was delineated at this site. One sample transect was established along the boundary in order to characterize the soil, vegetation, and existing hydrology within the wetland-to-upland transition zone. 111 I INTRODUCTION The subject parcel is approximately 2.77 acres and is dominated by terrace forest and grassland. I The topography of the site is terraced from the eastern and western part of the lot down to the wetland basin in the center with 10-15% slopes on each side. The surrounding land consists of both suburban single family homes and rural small farms (Figure 1). Currently the lot has one I house, two sheds and one small horse stable. The identified wetland was 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 Technical Documents section of this report contains field data sheets, plant indicator status information, soil survey information, and Iwetland definition information. 1 METHODS The methods used to delineate the subject parcel are as described in the 1987 US Army Corps of I 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 I 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. IThe 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. I "This Regional Supplement is part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland- I 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 considered adequately in a single national manual. The development of this 1 Svoboda Ecological Resources Bill&Mollie Reynolds Project Number: 2012-037 1 Orono,MN I I I I supplement follows National Academy of Sciences recommendations to increase I 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 I 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." I 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 I 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 the I Midwest Regional Supplement) and used to characterize wetland types and determine wetland boundaries. One sample transect was established in a representative wetland-to-upland transition zone in order to characterize the vegetation, soils, and hydrology of the site. A transect consists I 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. IHydrophytic status of plants was based on the National Wetland Plant List issued on May 15, 2012 and effective June 1, 2012 and as characterized by the plant status on the Excel Midwest IRegion data sheet provided by the US Army Corps of Engineers, St. Paul District. Wetland boundaries were marked at the site by pink "Wetland Delineation" pin flags. The I 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 I described by Cowardin et al. (1979) and used in the NWI (e.g. PEMB, PSS 1 C, 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 I section, was determined using the National List of Plant Species That Occur in Wetlands — Midwest Region (Lichvar, Robert W. and John T. Kartesz 2009). I RESULTS I The National Wetland Inventory indicates the presence of one wetland within the study area (Figure 2). This wetland is a palustrine emergent seasonally flooded wetland (PEMC). This wetland complex also consists of a PEMF within the PEMC wetland. This wetland may extend onto the site as well depending on the season. 1 Svoboda Ecological Resources Bill&Mollie Reynolds Project Number: 2012-037 2 Orono,MN I I The Web Soil Survey of Hennepin County (Figure 3) identified three soil map units within the study area; the Lester-Kilkenny complex, the Hamel-Glencoe depressional, the Hamel Outwash, and the Klossner. The Lester, Hamel outwash, and Hamel-Glencoe complex are considered to be partially hydric and Klossner complex is considered to be hydric. According to the Natural Resources Conservation Service (MRCS), partially hydric means "that at least one component of the map unit is rated as hydric, and at least one component is rated as not hydric." Soil series descriptions are provided in the Technical Documents section. The Minnesota Department of Natural Resources, (Public Water Inventory) indicates no public water within the study area(Figure 4). ' Site Visit SER ecologists examined the subject property for areas meeting jurisdictional wetland criteria during the site visit. One area meeting the jurisdictional criteria of a wetland was flagged, and the boundary determined and delineated. The approximate wetland boundary is outlined in yellow (Figure 5). Wetland 1 is a Type 4 PEMG deep marsh. The vegetation at sample point 1-1 UP consisted of a tree stratum and understory of black willow (Salix nigra, OBL) followed by an herb stratum ' consisting of a variety of grassland plants such as Kentucky bluegrass (Poa pratensis, FAC), orchard grass (Dactylis glomerta, FACU), smooth crab grass (Digitaria ischaemum, FACU), and upland wild timothy (Muhlenbergia racemosa, FACW). At sample point 1-1 WET the vegetation consisted of a tree layer of black willow (Salix nigra, OBL) followed by an herb layer of broadleaf cattail (Typha latifolia, OBL) and reed canary grass (Phalaris arundinacea, FACW). The transition from wetland to upland is characterized, in part, by this vegetative ' change. The soils at sample point 1-1 UP consisted of an initial 5 inches of 10YR 3/2 silty clay loam with 2 percent redoximorphic concentrations at 7.5 YR 4/6 in the matrix. The second horizon was 1 from 5-30 inches and was a 10YR 3/2 silty clay loam. The final horizon observed was from 30- 36 inches and was 10YR 6/1 with a silty clay texture. The soils at sample point 1-1 WET consisted of an initial 16 inches of 10YR 3/1 mucky peat followed by 16-30 inches of 10YR 2/1 111 silty clay. Hydric indicator Al (Histisol) was noted due to the 16 inches of mucky peat over silty clay. Wetland hydrology was observed at sample point 1-1 WET. Indicators B10 (Drainage Patterns) and D2 (Geomorphic Position) were present. Detailed soils, vegetation, and hydrology data for the delineated jurisdictional wetlands are provided in the data sheets of the Technical Documents section. I Svoboda Ecological Resources Bill&Mollie Reynolds Project Number: 2012-037 3 Orono,MN I I 1 DISCUSSION ISER 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, I and indicators of wetland hydrology in each basin. The site visit portion of the wetland delineation was completed on 9/10/12. I 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 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 IActivities 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 Ilevels by the provisions of the following legislative actions. ➢ State jurisdiction by the Wetland Conservation Act of 1991 (WCA)administered Iby the WCA Local Governmental Unit(LGU). ➢ Federal jurisdiction by the Clean Water Act of 1972 and subsequent amendments. I Wetland protection is implemented by the Corps of Engineers (Corps)with permit certification issued by the Environmental Protection Agency. I 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 I 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 I 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 I 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 according to current BWSR I and COE wetland rules and regulations approved wetland boundaries are typically valid for five years from the date of approval. ISvoboda Ecological Resources Bill&Mollie Reynolds Project Number: 2012-037 4 Orono,MN I I 1 1 To avoid project delays associated with wetland regulations, it is essential that you acquire 1 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. CERTIFICATION Blair Bollig completed the above-described delineation on 9/10/12. This delineation was P 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 I/GIS Specialist)on this ' day 9/12/12. The delineation report was reviewed by Frank Svoboda, President of Svoboda Ecological Resources.

I I I I THE TECHNICAL DOCUMENTATION SECTION IWetland Definition I I I I I I I I I I I I I I WETLAND DEFINITION IAccording 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 I 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 I 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 I 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 I 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 I SER ecologists has, in their professional judgment, delineated the wetlands on the subject parcel described in this report. I 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 I 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 I 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. IExcerpted from the 1987 Manual, Hydrologic Zones—Nontidal Areas Zone Name Duration Comments Wetland or Not Permanently Inundated 100% Inundation>6.6 ft.mean Not(Aquatic Habitat Zone,or Deep Water II water depth Semipermanently To Nearly <75- Inundation defined as Habitat) II Permanently Inundated Or <100% <_6.6 feet mean water Wetland I Saturated depth III Regularly Inundated Or >25-75% Wetland Saturated IV Seasonally Inundated Or <12.5-111 Wetland Saturated 25% Irregularly Inundated or ° Many areas having these Wetland(if hydrophytic veg.and hydric V Saturated >5-12.5/o hydrologic characteristics soils also present are not wetlands IIntermittently Or Never ° Areas with these VI Inundated Or Saturated <5% hydrologic characteristics Not are not wetlands I A-1 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 I I I I 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 I 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. I 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). IIn 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 I 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 Idelineation at the subject parcel of this report. Hydric Soil I 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 Ihydrophytic 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 Iupland 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 Iconsideration 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 I is large enough or the landscape features (vegetation or topography) change enough to warrant additional transect samples.
