Criteria for determining jurisdictional wetlands are as described in the 1987 U.S. ' Army Corps of Engineers Wetlands Delineation Manual (USCOE 1987 Manual) as re- quired by the Minnesota Wetland Conservation Act (WCA). , SITE DESCRIPTION The subject parcel is a vacant residential lot located at the intersection of Dickey Lake Drive and Willow Drive North (See Figure 1). The property includes deciduous forested ' areas located along the north and south border with an open grassy/shrub region covering the remaining middle portion of the parcel. (Figure 5). The surrounding landscape to the north and east is primarily single-family residential properties. Commercial property is ' located directly to the south of the subject parcel adjacent to Highway 12. Undeveloped land is located directly west of Willow Drive North. , METHODS National wetiand Inventory (NWI) maps (Figure 2), Soil Survey of Hennepin County maps (Figure 3), Minnesota Protected Waters maps (Figure 4), and aerial photographs ' are reviewed prior to the site visit to identify areas that may be wetlands. Areas illustrat- ing evidence of wetland conditions are examined in greater detail during the field survey. ' Three wetland criteria characteristics; vegetation, soils and hydrology (as outlined in the 1987 USCOE Manual), are examined during the survey and used to distinguish wetland types and determine wetland boundaries. A sample transect is established in representa- ' tive wetland-to-upland transition zones in order to characterize the vegetation, soils, and hydrology of the site. Information obtained from the sample points can be found on the , field data sheets located in Appendix A. 2�477 Shad�-wood Road • Excelsior, NII�1 55331 � ��s�� 4�1-iiou • ��s�� t-000� �F�� ' ' �1-toot woc�den lath. The"wetlanci b��undary" is considered to be the topographically hi�hest cxtent c�t�the wetland basin; areas below the stakcd boundary meet the three required wetland criteria while ' areas above are lackin� in one or more ot�these conditions. Wetland classitication follows methods described by Cowardin et al. (1979) and is used in the NW[ ' (e.g. PEMB, PSS1C, etc.), completed by the U.S. Fish and Wildlife Service. The Circular 39 wetland classification (Shaw and Fredine 1956) is also given (e.g. Type l, Type 2, etc.). The indicator status of plants,as described in Appendix B, is determined using the National List of Plant � Sp�cies That Occur in Wetlands — Rcgion 3 (Sabine 1999). RESULTS AND DISCUSS[ON ' Background Information- (Office-Based Investigation) The NWI map (Mound Quadrangle) illustrates one wetland on the subject parcel located at the central region of the southern perimeter(Figure 2).The basin shown on the NWI map is a palustrine ' type(P)wetland with emergent vegetation(EM),and a seasonally flooded moisture regime(C),or a Type 3, PEMC wetland. The Soil Sisrvey ofHennepin County indicates Cordova silty clay loam is present on the subject property (Figure 3). The Cordova series is classified as hydric soils (SCS ' Hydric Soils of the United States) and illustrated with blue crosshatching on Figure 3. The Minnesota Department of Natural Resources State Protected Waters Map indicates that 839W and , Dickey's Lake (161 W) occur in the vicinity of the subject parcel (See Figure 4). Site Visit , SER personnel examined the subject property for areas meeting jurisdictional wetland criteria during the site visit (July 16, 2004). An area meeting the jurisdictional criteria of a wetland, for which a boundary was determined, is comprised of one wetland basin(Type 3/6, PEM/FOl C) located near ' the southwest corner the parcel (Figure 5). Detailed soils, vegetation, and hydrology data for the delineated wetland is provided in the data sheets of Appendix A.Approximately 161ath were used to delineate this basin. The southern forested edge of the wetland,as well as topographic variation,was , used as the primary boundary cues while delineating this basin. Vegetation at the wetland sample point is dominated by reed canary grass (Phalaris arundinacea, ' FACW+) and sandbar willow (Salix exigua, OBL). Sub-dominant plant species present at the wetland sample include; swamp milkweed (Asclepias incarnata, OBL), lakebank sedge (Carex lacustris, OBL), Anemone (Anemone spp.), and silky dogwood (Cornus amomum, FACW+). , Dominant plants at the upland sample point consist of Canada goldenrod (Solidago canadensis, FACU) and Kentucky bluegrass (Poa pratensis, FAC-). ' Surface soils (<7") at the wetland sample point are composed of black (lOYR 2/1) clay loam that contains fibric features as deep as 4 inches. From 7 to 14 inches in the wetland soil profile,brown ' (l 0YR 5/3) common, fine, and faint mottles are present within the black (lOYR 2/1) clay loam matrix. Light yellowish brown(2.SY 6/3)clay loam with light gray(2.SY 7/1)calcareous depletions and brownish yellow (lOYR 6/8) few, medium and distinct iron oxide soft masses (IOSM) occurs ' from 14 to 18 inches. Light gray(2.SY 7/2) clay containing light yellowish brown (2.SY 6/4) few, tlne, and faint IOSM and white (2.SY 8/1) depletions are present beyond 18 inches. Water was observed 12 inches below the ground surface 10 minutes after boring. 1 ' ' ' Th e upland sample so�l consists ot black(1 OYR 2/l)clay loam trom the so�l surtace to a depth ot 13 ' inches with tibric characteristics occurring in the tirst 7 inches. No [OSM are present with 20 inches c�t�the soil surface. No water was observed within the upper 17 inches of the soil horizon in the upland sample borehole. ' Wetland vegetation was also noted in the road ditches along the west and south perimeter of the subject parcel.This ditched area was not delineated as a wetland because it is located within the road ' right-ot=way and is likely influenced by stormwater runoff via a culvert located in the southwest corner of the parcel (See Figure 5). ' RECOMMENDATIONS While the wetland boundary that SER has delineated is not official until approved by a WCA approved local government unit(LGU), SER advises the property owner to refrain from any filling, � draining,or excavating,or any impact to the area SER has delineated as wetland. 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,or located with a sub- meter GPS unit. Since the lath used along the boundary can be vandalized or inadvertently knocked ' over, a survey or GPS location of the lath 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. ' CONCLUSIONS SER examined the subject property and delineated one small wetland, located near the southwest ' corner of the parcel (Figure 5). All of the areas within the delineated wetland boundaries exhibit a dominance of hydrophytic vegetation, hydric soils, and wetland hydrology. This small basin likely collects enough water during excessive precipitation and during seasonally high water periods of the ' growing season that create conditions for wetland characteristics to become apparent. Please feel free to contact Coley Grostyan or Frank Svoboda at (952) 471-1100 if you have any ' questions or concerns regarding the information in this report. You will be receiving a follow-up phone call in two to three weeks to see if there is anything else that is needed. SER appreciates the opportunity to assist you with this project and we look forward to serving any future needs that you , might have.

The upper part of the profile in some of these soils formed in , modified glacial tilL These soils have moderately slow permeability. Their slopes are less than Z percent. Mean annual precipitation is about 28 inches. Mean annual temperature is about 48 degrees F. TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Typic Argiaquolls ' TYPICAL PEDON: Cordova clay loam with a plane slope of 1 percent in a cultivated field. (Colors are for moist soil unless otherwise stated.) ' Ap--O to 10 inches; black (N 2/0) clay loam, very dark gray (lOYR 3/1) dry; moderate medium subangular blocky structure; friable; about 1 percent gravel; neutral; abrupt wavy boundary. ' A--10 to 18 inches; black (N 2/0) clay loam, very dark gray(lOYR 3/1) dry; moderate medium subangular blocky structure; friable; about 1 percent gravel; neutral; clear wavy tboundary. (Combined A horizon is 8 to 20 inches.) Btgl--18 to 30 inches; olive gray (SY 4/2) clay loam; few fine prominent dark yellowish ' brown (l 0YR 4/6) Fe concentrations; moderate medium angular blocky structure parting to moderate fine angular blocky; friable; common very dark gray(SY 3/1) clay films on faces of peds and in pores; about 3 percent gravel; neutral; clear wavy boundary. ' Btg2--30 to 38 inches; olive gray(SY 5/2) clay loam; common fine prominent dark yellowish brown (lOYR 4/6) Fe concentrations; weak medium subangular blocky ' structure; friable; few distinct very dark gray(SY 3/1) clay films on faces of peds and in pores; about 3 percent gravel; neutral; abrupt wavy boundary. (Combined Btg horizon is 12 to 40 inches thick.) ' C--38 to 80 inches; light olive gray (SY 6/2) loam; common medium prominent yellowish brown (l 0YR 5/6) Fe concentrations; massive; friable; about 5 percent gravel; ' strongly effervescent; slightly alkaline. TYPE LOCATION: Waseca County, Minnesota; about 5 miles north of Waseca; 550 ' feet south and 1100 feet east of the northwest corner of Sec. 22, T.108N., R.22W.; USGS Morristown quadrangle; lat. 44 degrees 8 minutes 32 seconds N. and long. 93 degrees 27 minutes 45 seconds W., NAD27. ' RANGE IN CHARACTERISTICS: Depth to free carbonates ranges from 24 to 50 inches. Thickness of the mollic epipedon ranges from 10 to 24 inches. Rock fragment content is 2 to 6 percent throughout and is of mixed lithology, but some pedons have less ' than 2 percent in the upper part. The A horizons are neutral to moderately acid. The B horizons range from strongly acid to slightly alkaline. ' The Ap or A horizon has hue of lOYR, 2.SY or is neutral, value of 2 or 3 and chroma of 0 or 1. It is loam, silty clay loam, or clay loam. Eluviation is evident in some pedons by a few porous coatings on the faces of peds in the lower A and/or upper B horiozns. ' ' ' ' Sum� peci��ns have AB horiic�ns. The Bt� horizon has a matrix with hue of l0Y'R to SY, value of 3 to 5, value of 3 is only ' in thc; upper part, and chroma of I or 2. Some pedons have a BA horiron. The B horizon typically is silty clay loam or clay loam but ranges to loam in the lower part. The upper 20 inches of the argillic horizon averages between 28 to 35 percent clay and exceeds 15 ' percent fine sand and coarser. The B/A clay ratios range from 1.2 to l.4. A Bk horizon is present in some pedons. ' The C horizon has a matrix with �Y or 2.SY hue, value of 4 to 6, and chroma of 2 to 4. It is loam or clay loam and is slightly alkaline or moderately alkaline. ' COMPETING SERIES: These are the Barrv, Berville, Brookston, Buntin v� ille, Clackamas, Hamel, Jameston, Maren�;o, Mill�-ove, Navan, Nosoni, Rensselaer, and ' Westland series. Barry soils have less than 27 percent clay in the control section. Berville soils contain more than 6 percent gravel in the control section. Brookston soils are more moist in the soil moisture control section dunng the 120 days following the summer ' solstice and have less montmorillonite in the lower part of the series control section. Buntingville, Clackmas, and Nosoni soils are drier in the soil moisture control section during the 120 days following the summer solstice. Hamel soils have A horizons 16 to 27 ' inches thick and and chroma of 1 or less in the upper B horizons. Jameston soils have very firm till beginning at depths ranging from 18 to 30 inches. Marengo soils typically have thicker sola, contain appreciable amounts of sedimentary rock fragments in the silty ' clay lower B and C horizons, and are more moist in the soil moisture control section. Millgrove soils have up to 15 percent gravel in the upper part and 7 percent or more in the lower part of the control section and very poorly drained.. Navan soils have than 35 ' percent more clay in the lower B and C horizons. Rensselaer soils have reaction greater than 6.1 in the upper part of the control section, are more moist in the moisture control section and are poorly drained. Westland soils have 7 percent or more gravel in the lower ' part of the control section. GEOGRAPHIC SETTING: The Cordova soils have slightly concave to slightly convex ' slopes on broad flat ridge tops in rolling moraine areas or on lower lying areas in ground moraines and till plains. Slope gradients are 0 to 2 percent. Soils formed mostly in friable, calcareous, loamy till of Late Wisconsinan age. However, the upper part of the sola in ' some pedons is from modified glacial till or drift. The mean annual temperature is about c t� �� ,�o..,.00� c � ✓ U��L��J . . .�Zea;, a;ulual precipitation is about 26 to 32 inches. ' GEOGRAPHICALLY ASSOCIATED SOILS: The main ones are the Dundas, Lester, and Le Sueur soils. These soils formed in materials similar to those of the Cordova soils and are members of a hydrosequence with the Cordova soils. The well drained Lester ' soils are on nearby undulating to hilly slopes. The moderately well to somewhat poorly drained Le Sueur and the somewhat poorly to poorly drained Dundas soils are on nearby higher positions. The poorly drained Webster and Hamel soils and the very poorly ' drained Glencoe soils are a nearby associate in a few places. 1 ' ' ' DRA[NAGE AND PERMEABIL[TY: Poorly drained. Surface runoff is low. Pcrmeability is modcrately slow. ' USE AND VEGETAT[ON: Must of the soil is cleared, drained and cropped to corn and soybeans. A few areas remain in woodlots or permanent pasture. Native vegetation was northern hardwoods, largely basswood, maple, and elm, and an understory of grasses and ' sedges. DISTRIBUTION AND EXTENT: South-central Minnesota and north-central Iowa. , Extensive. MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota ' SERIES ESTABLISHED: Waseca County, Minnesota, 1963. REMARKS: Diagnostic horizons and features recognized are: Mollic epipedon from 0 ' to 18 inches (Ap and AB horizons); argillic horizon from 18 to 38 inches (Btgl and Btg2 horizons); aquic moisture regime - low chroma with redox features beneath the mollic ' epipedon.
