Dear Mr. Przymus:
Please find enclosed a copy of the wetland delineation report, prepared for the former
miniature golf facility along Highyway 5 and Galpin Boulevard in Chanhassen,
Minnesota. We have identified three wetland basins on the property.
As we discussed earlier, if any of the wetlands were created as a result of the construction
of 78th Street, an application of exemption may be made. I have discussed this possibility
with Lori Haak from the City of Chanhassen and she is looking into some historical aerial
photography for the property.
Please feel free to contact me at (952) 847-9637 with any questions you may have
regarding this report. Thank you for the opportunity to conduct this work on your behalf.
Very truly yours,
SCHOELL & MADSON, INC.

Wetland Classification, Identification and Delineation
for John przymus
Summary
Based upon the boundaries indicated on the site map provided to Schoell and
Madson, Inc., we have identified three wetland basins. The wetlands were field
identified on June 13, 2003. Total recorded rainfall at the Chanhassen Weather
Station for the week preceding the delineation was 1.93 inches. Cumulative
recorded rainfall for the month of June through the 13th was 0.77 inches.
Cumulative recorded rainfall for the month of May was 4.91 inches, 1.52 inches.
above normal.
Review of U.S. Fish and Wildlife National Wetland Inventory maps indicate one
PEMC wetland exists on this property.
Project Location and Site Description
The site is approximately 18 acres in size and is located along Galpin Boulevard
near the intersection of State Highway 5 in Chanhassen, Minnesota. The site was
formerly a miniature golf course and driving range.
Characteristics of Wetland Basin
Wetlands were delineated according to the 1987 Corps of Engineers Wetlands
Delineation Manuel.
Basin 1
Wetland 1 consists of a Type 2, Inland fresh meadow as defined in
Wetlands of the United States (USFWS Circular 39; Shaw and
Fredine 1971). Basin 1 is classified as a PEMB (Palustrine
Emergent Saturated) wetland based on the Wetlands and
Deepwater Habitats of the United States (FWS Publication 79/31;
Cowardin et al).

Vegetation
Observed vegetation along the wetland boundary consists of reed
canary grass Phalaris arundinacea, a facultative wetland (+) plant;
and curly dock Rumex crispus, a facultative (+) plant.
Vegetation inside the wetland boundary consists of reed canary
grass and narrow leaf cattail Typha angustifolia, an obligate wetland
plant.
Upland vegetation consists of bluegrass Poa sp.; reed canary grass;
and common plantain Plantago major, a facultative (+) plant.

Soils
The USDA Soil Survey of Hennepin County classifies the soils on the
property as Lester Loam. Boundary soils were field identified as
black (1 OYR 2/1) loam to a depth of 15 inches.
The upland soils were disturbed in the upper 10 inches. Below 10
inches, the Ab-horizon was identified as black (1 OYR 2/1) loam.
Wetland soils were-disturbed in the upper 10 inches. The
predominate matrix color was identified as black (1 OYR 2/1) with
5/5G gley. Yellowish brown (10YR 5/6) mottles were also present in
the wetland profile.
Hydr%gy
In the boundary pit, saturated soils were identified at a depth of 2
inches below the surface. Free water was encountered at 15 inches.
Saturated soils were encountered at a depth of 14 inches in the
upland pit. Free water was present at 15 inches below the surface.
In the wetland pit, saturated soils were present at a depth of 2
inches. Free water was encountered at 15 inches below the surface.
Basin 2
Wetland 2 consists of a Type 2, Inland fresh meadow as defined in
Wetlands of the United States (USFWS Circular 39; Shaw and
Fredine 1971). Basin 2 is classified as a PEMB (Palustrine
Emergent Saturated) wetland based on the Wetlands and
Deepwater Habitats of the United States (FWS Publication 79/31;
Cowardin et al).
Vegetation
Observed vegetation along the wetland boundary consists of reed
canary grass, bluegrass, and sow thistle Sonchus o/eraceus, a
facultative upland plant.
Vegetation inside the wetland boundary consists of reed canary
grass and smartweed Po/ygonum sp..
Upland vegetation consists of dandelion Taraxacum officina/e, a
facultative upland plant; and mowed field.

Soils
The USDA Soil Survey of Hennepin County classifies the soils on the
property as Lester Loam. Boundary soils were disturbed in the
upper 4 inches of the profile. Below 4 inches, the Ab-horizon was
identified as black (1 OYR 2/1) peat to a depth of 20 inches.
The upland soils were identified as black (1 OYR 2/1) peat to a depth
of 25 inches.
Wetland soils were disturbed in the upper 7 inches. Below 7 inches,
soil was identified as bl~ck (10YR 2/1) peat to a depth of 24 inches.
Hydrology
In the boundary pit, saturated soils were identified at a depth of 12
inches below the surface. Free water was encountered at 18 inches.
Saturated soils were not encountered in the upland pit.
In the wetland pit, saturated soils were present at a depth of 10
inches. Depth to free water is greater than 24 inches.
Basin 3
Wetland 3 consists of a Type 2, Inland fresh meadow as defined in
Wetlands of the United States (USFWS Circular 39; Shaw and
Fredine 1971). Basin 3 is classified as a PEMBd (Palustrine
Emergent Saturated ditched) wetland based on the Wetlands and
Deepwater Habitats of the United States (FWS Publication 79/31;
Cowardin et al).
Vegetation
Observed vegetation along the wetland boundary consists of reed
canary grass, smartweed, trembling aspen Populus tremula, a
facultative plant; and box elder Acer negundo, a facultative wetland
(-) plant.
Upland vegetation consists of giant foxtail Setaria faberi, a facultative
plant; golden-rod Solidago sp.; Aster sp.; mallow Napaea dioica, a
facultative wetland (-) plant; and thistle Circium sp..

Soils
The USDA Soil Survey of Hennepin County classifies the soils on the
property as Peat and Muck. Boundary soils were field identified as
black (1 OYR 2/1) peat to a depth of 25 inches. Marl was present in
the bottom half of the pit.
The upland soils were identified as black (1 OYR 2/1) peat to a depth
of 20 inches. Marl was present in bottom half of the pit.
Wetland soils were identified as black (1 OYR 2/1) peat to a depth of
30 inches. Marl was present throughout the profile.
Hydrology
Though saturated soils were not encountered in the boundary or
wetland pits, hydrology for the basin is assumed based upon the
predominance of hydrophytes and hydric soils.
Wetland Conservation Act
The site lies within the Riley Purgatory Bluff Creek Watershed District (RPBCWD)
boundaries. According to the Wetland Conservation Act of 1996, wetlands on this
site come under the jurisdiction of the Board of Water and Soil Resources. The
responsibility for administering the provisions of this legislation is up to the local
unit of government (LGU). In this case, the City of Chanhassen will oversee as
the LGU. The project must be certified by the LGU as having complied with the
provisions of the Act.
Any wetland impacts must be replaced or restored at a minimum ratio of 2 acres of
replacement for every 1 acre impacted. These mitigation activities must occur
within the same watershed as the impact occurs. The act also mandates that
restoration or creation of replacement wetlands only be considered after an
applicant has demonstrated that the impacts cannot be avoided, further minimized,
corrected, or eliminated over time. This requirement is essentially the same as the
U.S. Army Corps of Engineers permit process.
During the final design process, effort should be taken whenever possible to avoid
and minimize wetland impacts. By utilizing this approach, wetland replacement
costs will be kept to a minimum and any additional permitting will be more easily
facilitated. In addition, this strategy should result in a greater level of project
acceptance.
