SUMMARY
The project includes landslide repairs on the Minnesota Bluff LRT Regional Trail within the Hennepin County Regional
Railroad Authority (HCRRA) on the north and south side of the trail.
BACKGROUND
In June of 2014, several areas of the HCRRA’s corridor in Chanhassen were damaged by a storm. The most
significant damage was an 80foot slope failure that required total closure of the trail between Pioneer Trail and
Highway 101.
DISCUSSION
The Hennepin County Regional Railroad Authority (HCRRA) has submitted an application to excavate up to
approximately 24,800 cubic yards (CY) on a portion of the Minnesota Bluffs LRT Regional Trail located just
northwest of 220 Flying Cloud Drive (Moon Valley Aggregate). The purpose of this work is to repair damage due to
landslides that occurred after a high intensity rain event in June of 2014. Two repair areas will require grading and
excavation as part of the proposed permit – the north repair area and the south repair area.
RECOMMENDATION
Staff recommends approval of the Interim Use Permit to permit grading, excavation and slope restoration as proposed
on the plans prepared by Barr Engineering Co., dated December 13, 2019, subject to the Conditions of Approval and
adoption of the Findings of Fact.

Level of City Discretion in Decision-Making:
The city has limited discretion in approving or denying Interim Use Permits for grading, based on whether or
not the proposal meets the standards outlined in the Zoning Ordinance and Chapter 7 of the City Code. If the city
finds that all of the applicable standards are met, the permit must be approved. This is a quasi-judicial decision.
Notice of this public hearing has been mailed to all property owners within 500 feet.
PROPOSAL/SUMMARY
The project includes landslide repairs on the Minnesota Bluff LRT Regional trail within the Hennepin County
Regional Railroad Authority (HCRRA) on the north and south side of the trail. Landslide repair on the south
side will include stabilizing the south slope, repairing the south culvert outlet area and constructing a new storm
sewer and drainage ditch to direct water into the repaired area. Existing trail profile grades will be reduced with
the embankment slopes regraded to less steep grades and finished with turf reinforcement mats. The existing
damage concrete headwall will be removed and existing riprap will be salvaged for reuse. The south culvert
outlet area will be repaired with riprap, boulder cross vanes and a stilling basin. Work in the north area will
include removal of existing pipe debris, placement of riprap fill on the north slope and abandonment of the
existing pipe crossing beneath the trail. Drainage will be rerouted from the north pipe area via a new buried
storm sewer and lined drainage channel, which will discharge to the south culvert outlet area.

BACKGROUND
The trail ran on the embankment for 22 years; railroad cars ran on the embankment for almost 100 years before
that. In July 2014, several areas of the HCRRA’s corridor in Chanhassen were damaged by the storm events
grouped as Presidential Disaster 4182. The most significant damage was an 80-foot slope failure that required
total closure of the trail between Pioneer Trail and Highway 101. This trail is a well-used segment of a large
regional network that serves recreational and commuter users. Its closure requires a six-mile detour.
The HCRRA had worked with Federal Emergency Management Agency (FEMA) and State of Minnesota staff
since June 2014 to restore the slope and reopen the trail. The HCRRA planned to restore the slope in the
summer of 2016 before receiving notice from FEMA that their application for public assistance had been
denied. The denial was appealed in 2016, but public assistance was again denied.
GRADING
The Hennepin County Regional
Railroad Authority (HCRRA) has
submitted an application to excavate
up to approximately 24,800 cubic
yards (CY) on a portion of the
Minnesota Bluffs LRT Regional Trail
located just northwest of 220 Flying
Cloud Drive (Moon Valley
Aggregate). The purpose of this work
is to repair damage due to landslides
that occurred after a high intensity rain
event in June of 2014. Two repair
areas will require grading and
excavation as part of the proposed
permit – the north repair area and the
south repair area.
Landslide repairs in the south repair area, seen in Figure 1, will include: stabilizing the slope south of the
existing regional trail; repairing the south culvert outlet area by removing the existing damaged concrete
headwall, regrading, and installing a new pipe apron; constructing a new storm sewer and drainage ditch to
direct water into the repaired area; and reducing trail profile grades where the landslide occurred by regrading
the embankment slopes to less steep grades, coupled with the installation of turf reinforcement mats. This area
includes the rehabilitation of the stream bed.
Figure 1 - Construction Area
Planning Commission
Interim Use Permit, Planning Case No. 2020-01
January 21, 2020
Page 4
Work in the north repair area, seen in Figure
2, will include: removal of existing pipe
debris; placement of riprap fill on the slope
north of the existing trail; and abandonment
of the existing pipe crossing beneath the trail.
Drainage will be rerouted from the north pipe
area via a new horizontal directional drilled
storm sewer pipe to a lined drainage channel,
which will discharge to the south culvert
outlet area. Plans for redirecting the water
were provided to the Lower Minnesota River
Watershed District for review and comment
on December 12, 2019.
Stockpile areas have been identified to be
located in staging areas. Due to the limited
areas to stockpile material on site, the
applicant has expressed that the contractor
will likely choose to put any excavated
material directly in trucks to export.
Excavated material will include soil and
unsalvageable riprap. The total estimated quantity provided by the applicant of excavated material is 22,814
CY, with 19,990 CY being common (non-contaminated) and 2,824 CY being special (contaminated material).
The contaminated soils were limited to shallow soils on or near the trail and are attributed to the fact that the
trail was a past railroad line. The applicant has indicated that all contaminated soils will be exported offsite to
an approved waste disposal facility as recommended by the Environmental Soil Investigation provided on
April 4, 2018 by Kevin Eisen, PE, PMP, a Senior Geological Engineer with BARR.
The applicant is proposing two separate accesses to the repair areas. Access to the north repair area will be
from Highview Drive along the trail, located in Eden Prairie, while access to the south repair area is tentatively
planned to be from Flying Cloud Drive via the Moon Valley Aggregate property. Both accesses will require
permissions from each entity: a right-of-way (ROW) permit from the City of Eden Prairie, and a private access
agreement with Moon Valley Aggregate and the landowner. Along with applicable ROW permits and access
agreements, any work that encroaches into adjacent properties outside HCRRA’s property will require
temporary construction easement(s).
Figure 2 - South Repair Area
Planning Commission
Interim Use Permit, Planning Case No. 2020-01
January 21, 2020
Page 5
The equipment that will utilize the access
routes will include a backhoe (or similar
excavator), small bulldozers, light bobcat(s)
and trucks to transport personnel, equipment
and material. It is proposed that construction-
related traffic and haul routes will utilize
Hennepin County Highway 1 (Pioneer Trail)
and Carver County Highway 61 (Flying Cloud
Drive) to get to and from the sites. Flying
Cloud Drive will be rated for a 10-ton per axle
road. All oversize/overweight loads leaving
the site to the east must apply for County
Transportation OS/OW trip permits.
Although there are no residential, commercial
or industrial developments immediately
adjacent to the areas where construction will
be taking place, construction traffic will be
utilizing the trail which does run near
residential areas. The applicant is proposing
that the work is anticipated to occur between
the months of February and December of 2020.
Due to the period of construction and the proximity of residential areas near the trail, construction hours will be
limited to those hours listed in Sec. 13-52.c of City Ordinance which pertain to construction activities in
conjunction with improvement projects (7:00 a.m. to 6:00 p.m. on weekdays and 9:00 a.m. to 5:00 p.m. on
Saturdays with no work on Sundays or public holidays). Any requests to work beyond those hours shall be
made to the Public Works Director/City Engineer for review and approval. The applicant should be aware that if
excess material is transported to another site in Chanhassen, a separate grading permit will be required for the
other property.
The applicant has submitted plans showing tree removal and restoration to be done as part of the trail repairs.
On either side of the trail are non-developed areas that are fully wooded with native species, such as maples,
lindens, oaks, elms, cottonwoods, etc. On the south side of the trail there is an outlot of Settlers West, owned
by the city and covered by a Conservation Easement. The construction plans show no impact to this area, but
construction limits are directly adjacent to the outlot so staff will be monitoring to ensure there is no
encroachment.
Tree removal will occur along the trail in the repair areas shown in the plans. City Code requires trees 6” and
larger to be shown on plans. However, due to the density of trees, it was recommended to the applicant that a
field inventory during the project will be better suited to the conditions. Therefore, restoration quantities are not
available with the application. Staff will be monitoring and confirming the tree removal for the project and the
applicant is required to plant replacements at a rate of 1:1 for all trees 6” and larger. Replacement trees will be
selections of native overstory and understory species.

EROSION CONTROL
Erosion control has been shown on the plan in general conformance with City Ordinance Sec. 19-145 (Erosion
and Sediment Control) and industry best management practices. Efforts shall be made by the applicant to
ensure erosion control practices remain up to date with city standards, ordinances, and best management
practices. If erosion control measures installed in conjunction with this IUP are deemed by the city to be
ineffective, the city will inform the applicant in writing of any deficiencies. The applicant will be required to
remedy the deficiencies prior to continuing construction operations. Furthermore, upon completion of the
installation of initial erosion control measures as illustrated on the Erosion Control Plan and SWPPP, the
contractor shall contact the city for an initial erosion control inspection prior to grading operations.
Silt fence shall be furnished in accordance with MnDOT Construction Standards, Section 3886. Machine sliced
(MS) or hand installed (HI) woven geotextile silt fence must be installed in all areas specified in the Erosion
Control Plan. MS or HI woven geotextile silt fence must be reinforced using sediment logs, wire backing, or
other effective Best Management Practice.
Phasing is a very important management tool for erosion control, thus one repair area should be stabilized prior
to grading and construction operations of the next repair area. Stabilization of the slope north of the repaired
culvert in the south repair area is needed immediately upon final grading. Stabilization should continue to be
done in phases. Large portions of the site should not be left exposed over weekends or during forecasted heavy
rains. Due to the steep slopes and long runs of the slopes, bio-rolls may be needed to aid in stabilization. Bio-
rolls would help break up the length of slope and minimize erosion potential of the slope with the erosion
control blankets. Six-inch bio-rolls are needed every 15 to 20 feet on steep slopes with exposed soils. Proper
blanket application is crucial for this site. The blankets must make 100% contact with the soil and stapled
according to manufacturer’s specifications. The staple pattern is vital to proper blanket function. The blankets
should be head trenched as well. Geotextile and riprap or geogrids or other approved stabilization is needed to
provide toe protection; there is a chance the toe of the 2:1 slope may start head cutting without toe protection.
Depending on the final soil-used blanket, application may be difficult. For example if the soil is too sandy,
stapling the blanket over long runs will not be successful. ‘Terracing’ blankets or using strips of blankets with a
heavy application of seed mix (20 pounds per acre) and hydromulch may be needed.
Exposed, unworked soils must continue to be stabilized with temporary or permanent stabilization BMPs in
accordance with the construction sequencing as stated in the Erosion Control Plan and the SWPPP.
Additionally, unworked erodible soils with positive slopes must continue to be stabilized using erosion control
blanket or alternate effective BMPs.
Subsurface stormwater movement should be considered with surface movement of stormwater. The applicant
provided figures of ground water elevations from the County Atlas Series, Carver County, Atlas C-21, Part B,
Plate 6. When considering stormwater management, installation of draintile at the toe should be considered to
reduce any future possibility of sloughing due to saturation from ground water or slope seepage.
DRAINAGE
In conjunction with the landslide repairs in the north area, the applicant is proposing to abandon an existing 18”
ductile iron stormwater pipe that is located under the Minnesota Bluffs LRT Regional Trail. The existing
stormwater pipe to be abandoned conveys treated stormwater from the neighboring subdivision, known as
“Settlers West”. In order to re-route the treated stormwater, the applicant has proposed to install a 24” HDPE
Planning Commission
Interim Use Permit, Planning Case No. 2020-01
January 21, 2020
Page 7
storm sewer pipe via horizontal directional drilling (HDD) to the west, replacing the abandoned conveyance
system to the north (under the Regional Trail), as seen from Figure 4. To ensure the HDD HDPE pipe can be
located in the future, it shall be furnished with tracer wire meeting the City of Chanhassen’s Standard
Specifications. Furthermore, HDD specifications should conform to the city’s Standard Specifications.
Figure 4 - North Area Stormwater Conveyance Reconfiguration
Rather than stormwater being conveyed under the trail and discharged to the north, the HDD pipe will discharge
drainage from the subdivision to the west into a proposed drainage channel, as seen from Figure 5. The
drainage channel will be constructed of a flexible concrete geogrid with rock checks installed approximately
every 50 feet. Additionally, a riprap stilling basin will be installed near the outlet of the HDD pipe to further
assist with energy dissipation and minimization of downstream scouring of the stream bed. While it appears
best practices and proper techniques were utilized in the design of these conveyance systems (size of HDPE
pipe, stilling basins, check dam spacing, etc.) the applicant did not provide hydraulic calculations or a drainage
report for review. The applicant shall submit hydraulic design calculations and follow-up analysis for the newly
proposed stormwater conveyance system, including analysis for riprap stilling basins and rock check dams as
energy dissipaters for a 100-year event. Upon submittal of this analysis, 100% plans shall be provided as the
applicant provided 90% plans with their IUP application.

Lastly, stormwater infrastructure and appurtenances will eventually require maintenance, repairs, and potential
upgrades. As these improvements will not be owned and maintained by the City of Chanhassen, the applicant
shall enter into maintenance agreements with the city and/or Lower Minnesota River Watershed District to
ensure maintenance responsibilities and ownership are the responsibility of the HCRRA or their designee, in
perpetuity.
WETLANDS
The applicant is proposing 0.06 acres of temporary impact to WCA jurisdictional wetlands (Sheet G-05 and
G-06). The applicant has claimed that these wetlands are manmade ditch wetlands and should be considered
incidental, and thus not regulated under WCA. The applicant did not provide any evidence as to why these
should be considered incidental (as-builts, soils data, topography, historical aerials, etc.). While initial in-house
desktop review likely supports this claim, any evidence that might show these are in fact incidental wetlands
needs to be provided by the applicant. This can be accomplished through the WCA permit process that is
currently underway, in which a Notice of Decision on whether the wetlands being impacted are incidental or not
can be issued.

CITY OF CHANHASSEN
CARVER AND HENNEPIN COUNTIES, MINNESOTA
FINDINGS OF FACT
AND RECOMMENDATION
IN RE:
Application of Hennepin County Regional Railroad Authority (HCRRA) for an Interim Use
Permit to permit grading, excavation and slope restoration.
On January 21, 2020, the Chanhassen Planning Commission met at its regularly
scheduled meeting to consider the application of Hennepin County Regional Rail Authority for
an Interim Use Permit for the property located north of 220 Flying Cloud Drive within the right-
of-way for the Minnesota River Bluffs LRT Regional Trail. The Planning Commission
conducted a public hearing on the proposed interim use which was preceded by published and
mailed notice. The Planning Commission heard testimony from all interested persons wishing to
speak and now makes the following:
FINDINGS OF FACT
1. The property is currently zoned Agricultural Estate District (A2).
2. The property is guided by the Land Use Plan for Residential High Density use.
3. The legal description of the property is:
Hennepin County Regional Railroad Authority (HCRRA) right-of-way fo r Minnesota River
Bluffs LRT Regional Trail in Sections 25, 34, 35 and 36, Twsp 116, Range 23, Carver
County, Minnesota
4. When approving an Interim Use Permit, the city must determine the capability of a proposed
development with existing and proposed uses. The general issuance standards of the
conditional use Section 20-232, include the following 12 items:
a. The mining operation will not be detrimental to or endanger the public health, safety,
comfort, convenience or general welfare of the neighborhood or the city. The site work
will result in the stabilization and re-vegetation of the slope and the reduction in site
erosion.
b. The slope restoration and stormwater improvements will be consistent with the objectives
of the city's comprehensive plan and the zoning code by the protection and stabilization
of the slopes.
c. The slope restoration and stormwater improvements will be designed, constructed,
operated and maintained so to be compatible in appearance with the existing or intended
2
character of the general vicinity and will not change the essential character of that area
because the site will be re-vegetated and the slopes stabilized reducing site erosion. The
aesthetics of the site will be enhanced with the elimination of the slope sluffing,
gullies/ravines in the site and the establishment of site vegetation.
d. The slope restoration and stormwater improvements will not be hazardous or disturbing
to existing or planned neighboring uses because the grading and drainage will be
contained within the site perimeters. Additionally, hours of operation are limited and
specific conditions of approval will be in place and enforced by the city.
e. The slope restoration and stormwater improvements will be served adequately by
essential public facilities and services, including streets, police and fire protection,
drainage structures, refuse disposal, water and sewer systems and schools; or will be
served adequately by such facilities and services provided by the persons or agencies
responsible for the establishment of the proposed use. The use is temporary which does
not need to be served by public facilities and services. The proposed grading will reduce
or eliminate erosion on the slope.
f. The slope restoration and stormwater improvements will not create excessive
requirements for public facilities and services and will not be detrimental to the economic
welfare of the community since this is a temporary use. The repair of the slope will
reopen a regional trail corridor, which is heavily used.
g. The slope restoration and stormwater improvements will not involve uses, activities,
processes, materials, equipment and conditions of operation that will be detrimental to
any persons, property or the general welfare due to excessive production of traffic, noise,
smoke, fumes, glare, odors, rodents, or trash. The proposed grading could result in a
temporary increase in traffic, noise and fumes. The conditions of the approval will
provide standards by which the activities should be minimized.
h. The slope restoration and stormwater improvements will have vehicular approaches to the
property which do not create traffic congestion or interfere with traffic or surrounding
public thoroughfares. Through the use of signage, limits on the hours of operation, and if
traffic becomes congested, additional limits on the hours of hauling operation could be
instituted and potential traffic problems will be mitigated.
i. The slope restoration and stormwater improvements will not result in the destruction, loss
or damage of solar access, natural, scenic or historic features of major significance. The
proposal will result in the removal of some existing canopy. However, the site will be re-
vegetated and there will be less bluff impact.
j. The slope restoration and stormwater improvements will be aesthetically compatible with
the area since the grading and re-vegetation of the site will improve the site aesthetics.
3
k. The slope restoration and stormwater improvements will not depreciate surrounding
property values since the plan will improve the site and its impacts on the surrounding
properties.
l. The slope restoration and stormwater improvements will meet standards prescribed for
certain uses as provided in Chapter 7, Article III of the Chanhassen City Code.
5. The planning report #2020-01 dated January 21, 2020, prepared by Erik Henricksen, et al, is
incorporated herein.
RECOMMENDATION
The Planning Commission recommends that the City Council approve the Interim Use
Permit to permit grading, excavation and slope restoration subject to the conditions of the staff
report.
ADOPTED by the Chanhassen Planning Commission this 21st day of January, 2020.

1 Introduction
This application is prepared to fulfill the City of Chanhassen Interim Use Permit requirements as outlined
in the City Code Chapter 7, Article III, Section 7-35. The application is organized to correspond to each
numbered item under Section 7-35 (b).
Project Description
The scope of the project includes landslide repairs on a portion of the Minnesota Bluffs LRT Regional Trail
in Chanhassen, MN owned by the Hennepin County Regional Railroad Authority (HCRRA). Two areas will
be repaired as part of this project – the north repair area and the south repair area. Project access will be
from Highview Drive in Eden Prairie, proceeding southwest along the trail to the site, and also from Flying
Cloud Drive through the Moon Valley Aggregate operated property (final access route through Moon
Valley Aggregate operated property pending property owner authorization).
Landslide repairs in the south repair area will include stabilizing the south slope, repairing the south
culvert outlet area and constructing a new storm sewer and drainage ditch to direct water into the
repaired area. Plans for redirecting the water were provided to the Lower Minnesota River Watershed
District for review and comment on December 12, 2019. The response from the watershed district will be
provided to the City upon receipt.
Existing trail profile grades will be reduced with the embankment slopes regraded to less steep grades
and finished with turf reinforcement mats. The existing damaged concrete headwall will be removed and
existing riprap will be salvaged for reuse. The south culvert outlet area will be repaired with riprap,
boulder cross vanes, and a stilling basin.
Work in the north area will include removal of existing pipe debris, placement of riprap fill on north slope,
and abandonment of the existing pipe crossing beneath the trail. Drainage will be rerouted from north
pipe area via new buried storm sewer and lined drainage channel, which will discharge to the south
culvert outlet area.

Proof of ownership is provide in Attachment 1.
Item 2: The correct legal description of the property where the activity is proposed to occur.
All that part of a variable width strip of land in Sections 34, 35, 36 and 25, Township 116, Range 23, Carver
County, Minnesota, being former railroad right of way. Subject to existing public roads and highways, and
easements of record, if any.
Item 3: A certified abstract listing the names of all landowners owning property within 500 feet of
the boundary of the property described above.
The City of Chanhassen provided the applicant with a list of landowners located within 500 feet of the
property boundary on December 2, 2019. Refer to Attachment 2.
Item 4: Specifications of the following, using appropriate maps, photographs and surveys:
Full project specifications are provided in the construction design plans as Attachment 3. Draft
specifications for horizontal directional drilling (HDD) are provided as Attachment 4. Once a final copy of
the HDD specifications is available it will be provided to the city.
a. Proposed grading plan
Refer to the attached construction design plans, sheet G-08 (Attachment 3).
b. Proposed stockpile sites
Stockpiling will occur in the areas identified as staging areas on plan sheet G-05 (Attachment 3). There is
limited space for stockpiling material on the site. The contractor will likely choose to put any excavated
material directly in trucks to export from the site and stockpile temporarily stripped topsoil on site. It is
likely that material will also need to be imported and stockpiled at the site within the staging areas on
plan sheet G-05 (Attachment 3). Imported material will include riprap, granular filter, and topsoil.
c. The physical relationship of the proposed designated site to the community and existing
development.
The project site is located on a portion of the Minnesota Bluffs LRT Regional Trail in the Rice Lake area just
north of Flying Cloud Drive. The project will take place on Hennepin County Regional Railroad Authority
property. Two repair areas are part of this project – north repair area and south repair area. A gravel pit
owned by Moon Valley Aggregate is located southeast of the south repair area. There are no other
residential, commercial or industrial developments immediately adjacent to the north and south repair
3
areas. Residential areas are located on either side of the trail in the northeast portion of the project area
(Figure 1). The northeast portion of the trail will be used for construction access only.
d. Site topography and natural features including location of watercourses and waterbodies.
The trail slopes down from the northeast towards the southwest with an approximate elevation of 880
feet at the northeast access point coming down to 830 feet at the south repair area. Topography on either
side of the trail is variable but generally downward sloping. Refer to sheet G-08 (Attachment 3) and Figure
2 for elevation contours within the project area. Wetlands are located on either side of the trail along the
access with a small percentage located within the construction limits (Figure 3 and 4; sheets G-05 and G-
06, Attachment 3). A small wetland is located northeast of the north repair area outside of the
construction limits (Figure 4). A stream channel runs adjacent to the trail from the northeast. The stream
channel is outside of the construction limits at the north repair area and flows under the trail via the south
culvert in the south repair area (Figure 4). No other waterbodies are located within the project footprint.
The site is not within a designated floodplain (Figure 5). A Public Water Inventory basin (unnamed) is
located northwest of the access at Highview Drive but is not within project limits and will not be impacted
by construction activities (Figure 6).
e. The description and quantity of material to be excavated.
Excavated material will include soil and riprap. The total estimated quantity of excavated material is:
• Excavation – common (non-contaminated material): 19,990 cubic yards
• Excavation – special (contaminated soil): 2824 cubic yards
The trail lowering portion of the project will require extensive excavation and some of the material on the
surface is contaminated. Contaminated soil will be exported offsite to an approved waste disposal facility.
No new soil will be needed as the finished grade is much lower than existing grade.
f. The depth of water tables throughout the area.
Refer to Figures 7 and 8 for water table depths/elevations. Depth to water table is approximately 0 to 25
feet in most of the south repair area, 25 to 75 feet along the trail and, 0 to 25 feet in the north repair area.
g. The location and depth of wells and buried garbage, water and fill.
There are no public or domestic wells within the project footprint, refer to Figure 8. No buried garbage or
fill was identified at the site.
Item 5: The purpose of the operation.
The purpose of the planned work is to repair landslides along a portion of the Minnesota Bluffs LRT
Regional Trail that occurred in 2014. In addition to the landslide repairs, a new storm sewer and drainage
channel are proposed to be constructed on the south side of the trail that will drain to the south culvert
area. The south culvert will also undergo repairs. The culvert located in the north repair area will be filled
and abandoned in place.
4
Item 6: The estimated time required to compete operation.
Tree clearing will occur prior to the work required to complete the repairs. In total, construction time is
expected to be no greater than ten months.
Item 7: Hours and months of operation.
Work will occur within regular hours, starting no earlier than 7:00 a.m. and finishing no later than 6:00 p.m.
on a daily basis. Work is anticipated to occur between the months of February and December of 2020.
Item 8: A tree survey indicating the location and type of all trees over six inches in caliper. In a
heavily wooded area only the boundaries of the tree areas must be indicated on the survey.
A tree survey was conducted to identify trees over 6 inches in diameter at breast height (dbh). The area
within the construction limits is heavily wooded. Collecting individual tree locations was not feasible given
that the area is heavily wooded. Instead, a square measuring 2,500 square feet was surveyed in three
different locations along the south repair area. On average, about 7 trees at or above 6 inches dbh were
identified within the surveyed squares. Tree clearing will take place in areas as necessary within the limits
of construction (Attachment 3) and will be avoided to the extent practicable. Trees over 6 inches dbh that
are removed during construction will be counted and replanted at a 1:1 ratio within the construction limits
during restoration as space allows. Some areas where trees will be removed will not be replanted due to
new features being constructed. Refer to sheet R-03 (Attachment 3) for the tree replacement plan.
Item 9: An end use landscape plan and interim screening plan for the operation period.
The restoration plan is provided in Attachment 3, sheets R-01 through R-04. An interim screening plan is
not applicable to this project.
Item 10: The plan of operation, including processing, nature of the processing and equipment,
location of the plant source of water, disposal of water and reuse of water.
Not applicable.
Item 11: Travel routes to and from the site and the number and type of trucks that will be used.
Access to the north repair area will be from Highview Drive along the trail. An access road will be
constructed from Highview Drive for truck and equipment access. An application for a right-of-way permit
will be submitted to the City of Eden Prairie once the contractor has been selected and construction dates
are finalized. The City of Eden Prairie permit is required to obtained authorization for constructing a
temporary access route in the City of Eden Prairie right-of-way. The timeline for submitting the
application in late winter/spring of 2020 and the application requirements have been discussed with the
City of Eden Prairie. Access to the south repair area will be from Flying Cloud Drive via Moon Valley
Aggregate property (pending owner approval). Equipment used will include a backhoe or similar
excavator, small bulldozers, light bobcat(s), and trucks to transport personnel, equipment and material.
5
Beyond the direct access routes into the project area, it is anticipated that most construction related traffic
would use County Highway 1 and County Highway 61.
Item 12: Plans for drainage, erosion and sediment control and dust control.
No drainage will occur as part of this project. Erosion and sediment control best management practices
(BMPs) are outlined in the storm water pollution prevention plan (SWPPP) included in Attachment 3,
sheets C-05 and C-06.
Item 13: A restoration plan providing for the orderly and continuing restoration of all disturbed
land to a condition equal to or better than that which existed prior to the earth work. Such plan
shall illustrate, using photographs, maps and surveys where appropriate, the following:
a. The contour of the land prior to excavation and proposed contours after completion of
excavation and after completion of restoration.
Refer to Figure 2 for current topographic contours and refer to Attachment 3, sheet G-08 for topographic
contours after project completion (regraded area along trail modifications).
b. Those areas of the site to be used for storage of topsoil and overburden.
The site does not currently contain much topsoil. It is anticipated that the contractor will strip what topsoil
they can and stockpile it in the staging areas, but most of the topsoil used in site restoration will likely
need to be imported.
c. A schedule setting forth the timetable for excavation of land lying within the extraction facility.
Refer to items 6 and 7 for a schedule of the proposed activities.
d. The grade of all slopes after restoration, based upon proposed land uses, and description of the
type and quantity of plantings where revegetation is to be conducted.
Refer to Attachment 3, sheets G-08 for area that will be regraded and sheets R-01 through R-03 for the
restoration plans. The construction area will be re-seeded using MnDOT approved seed mixes. Types of
seed mixes are outlined on the restoration plan (sheet R-01, Attachment 3) with a total area to be seeded
of up to 7.41 acres.
e. The criteria and standards to be used to achieve final restoration as well as intermittent
stabilization.
Intermittent stabilization will be achieved with the use of erosion and sediment control BMPs. Final
restoration will be achieved per the restoration plan (sheet R-01 through R-03, Attachment 3). For further
information refer to the SWPPP on sheets C-05 and C-06 (Attachment 3).
6
Item 14: A statement identifying the applicant's program to insure compliance with the permit
conditions, method of response to complaints and resolving conflicts that may arise as a result of
complaints.
HCRRA will obtain coverage under the Minnesota Pollution Control Agency’s General Permit for
Construction Stormwater. As such, required inspections under that coverage will be completed and will
serve as means to oversee compliance with the permit conditions. Conflicts that are brought to the City’s
attention can be directed to Jessica Galatz (612) 348-2691.
Item 15: Unless exempt under Minnesota Rules, an environmental assessment worksheet, if
required by the city.
Not applicable.
Item 16: A wetland alteration permit, if required by the City Code, which shall be processed
concurrently with the excavation permit application.
A joint application form for activities affecting water resources in Minnesota was submitted to the U.S.
Army Corps of Engineers and serves to fulfill the city’s wetland alteration requirement. It is provided as
Attachment 5 for reference.
The application materials are supported by field delineations completed in 2015 and 2019. Delineation
work was confirmed by the City of Chanhassen’s technical evaluation panel, as noted in the attached
application materials.

Minnesota Interagency Water Resource Application Form February 2014 Page 1 of 15
Joint Application Form for Activities Affecting Water Resources
in Minnesota
This joint application form is the accepted means for initiating review of proposals that may affect a water resource (wetland,
tributary, lake, etc.) in the State of Minnesota under state and federal regulatory programs. Applicants for Minnesota Department
of Natural Resources (DNR) Public Waters permits MUST use the MPARS online permitting system for submitting applications to
the DNR. Applicants can use the information entered into MPARS to substitute for completing parts of this joint application form
(see the paragraph on MPARS at the end of the joint application form instructions for additional information). This form is only
applicable to the water resource aspects of proposed projects under state and federal regulatory programs; other local
applications and approvals may be required. Depending on the nature of the project and the location and type of water resources
impacted, multiple authorizations may be required as different regulatory programs have different types of jurisdiction over
different types of resources.
Regulatory Review Structure
Federal
The St. Paul District of the U.S. Army Corps of Engineers (Corps) is the federal agency that regulates discharges of dredged or fill
material into waters of the United States (wetlands, tributaries, lakes, etc.) under Section 404 of the Clean Water Act (CWA) and
regulates work in navigable waters under Section 10 of the Rivers and Harbors Act. Applications are assigned to Corps project
managers who are responsible for implementing the Corps regulatory program within a particular geographic area.
State
There are three state regulatory programs that regulate activities affecting water resources. The Wetland Conservation Act
(WCA) regulates most activities affecting wetlands. It is administered by local government units (LGUs) which can be counties,
townships, cities, watershed districts, watershed management organizations or state agencies (on state-owned land). The
Minnesota DNR Division of Ecological and Water Resources issues permits for work in specially-designated public waters via the
Public Waters Work Permit Program (DNR Public Waters Permits). The Minnesota Pollution Control Agency (MPCA) under Section
401 of the Clean Water Act certifies that discharges of dredged or fill material authorized by a federal permit or license comply
with state water quality standards. One or more of these regulatory programs may be applicable to any one project.
Required Information
Prior to submitting an application, applicants are strongly encouraged to seek input from the Corps Project Manager and LGU staff
to identify regulatory issues and required application materials for their proposed project. Project proponents can request a pre-
application consultation with the Corps and LGU to discuss their proposed project by providing the information required in
Sections 1 through 5 of this joint application form to facilitate a meaningful discussion about their project. Many LGUs provide a
venue (such as regularly scheduled technical evaluation panel meetings) for potential applicants to discuss their projects with
multiple agencies prior to submitting an application. Contact information is provided below.
The following bullets outline the information generally required for several common types of determinations/authorizations.
• For delineation approvals and/or jurisdictional determinations, submit Parts 1, 2 and 5, and Attachment A.
• For activities involving CWA/WCA exemptions, WCA no-loss determinations, and activities not requiring mitigation,
submit Parts 1 through 5, and Attachment B.
• For activities requiring compensatory mitigation/replacement plan, submit Parts 1 thru 5, and Attachments C and D.
• For local road authority activities that qualify for the state’s local road wetland replacement program, submit Parts 1
through 5, and Attachments C, D (if applicable), and E to both the Corps and the LGU.

Submission Instructions
Send the completed joint application form and all required attachments to:
U.S Army Corps of Engineers. Applications may be sent directly to the appropriate Corps Office. For a current listing of areas of
responsibilities and contact information, visit the St. Paul District’s website at:
http://www.mvp.usace.army.mil/Missions/Regulatory.aspx and select “Minnesota” from the contact Information box.
Alternatively, applications may be sent directly to the St. Paul District Headquarters and the Corps will forward them to the
appropriate field office.
Section 401 Water Quality Certification: Applicants do not need to submit the joint application form to the MPCA unless
specifically requested. The MPCA will request a copy of the completed joint application form directly from an applicant when they
determine an individual 401 water quality certification is required for a proposed project.
Wetland Conservation Act Local Government Unit: Send to the appropriate Local Government Unit. If necessary, contact your
county Soil and Water Conservation District (SWCD) office or visit the Board of Water and Soil Resources (BWSR) web site
(www.bwsr.state.mn.us) to determine the appropriate LGU.
DNR Public Waters Permitting: In 2014 the DNR will begin using the Minnesota DNR Permitting and Reporting System (MPARS) for
submission of Public Waters permit applications (https://webapps11.dnr.state.mn.us/mpars/public/authentication/login).
Applicants for Public Waters permits MUST use the MPARS online permitting system for submitting applications to the DNR. To
avoid duplication and to streamline the application process among the various resource agencies, applicants can use the

This application is related to the Chanhassen Slope Failure project number 2015-04215-MMJ. A wetland
delineation was previously conducted in August 2015. This wetland delineation report was approved on December
18, 2015 (Appendix A). A second wetland delineation was completed on September 2019, for the expanded
project area. This wetland delineation has been reviewed by the technical evaluation panel and the approval letter
is attached.
Minnesota Interagency Water Resource Application Form February 2014 Page 4 of 15
Describe the project that is being proposed, the project purpose and need, and schedule for implementation and completion. The
project description must fully describe the nature and scope of the proposed activity including a description of all project elements
that effect aquatic resources (wetland, lake, tributary, etc.) and must also include plans and cross section or profile drawings
showing the location, character, and dimensions of all proposed activities and aquatic resource impacts.
Project Description:
The scope of the project includes landslide repairs on a portion of the Minnesota Bluffs LRT Regional Trail (trail) in
Chanhassen, MN owned by the Hennepin County Regional Railroad Authority (HCRRA). Two areas will be repaired
as part of this project – the north repair area and the south repair area. Project access will be from Highview Drive
in Eden Prairie, proceeding southwest along the trail to the site, and also from Flying Cloud Drive through the
Moon Valley Aggregate operated property (final access route through Moon Valley Aggregate operated property
pending property owner authorization).
Landslide repairs in the south repair area will include stabilizing the south slope, repairing the south culvert outlet
area and constructing a new storm sewer and drainage ditch to direct water into the repaired area. Existing trail
profile grades will be reduced with the embankment slopes regraded to less steep grades and finished with turf
reinforcement mats. The existing damaged concrete headwall will be removed and existing riprap will be salvaged
for reuse. The south culvert outlet area will be repaired with riprap, boulder cross vanes, and a stilling basin.
Work in the north area will include removal of existing pipe debris, placement of riprap fill on north slope, and
abandonment of the existing pipe crossing beneath the trail. Drainage will be rerouted from north pipe area via
new buried storm sewer and lined drainage channel, which will discharge to the south culvert outlet area.Please
refer to Appendix B for the complete set of design plans and layout of the aforementioned project featrues.
Project Purpose and need
In 2014, a large rain event (presidential declared disaster 41823) caused the slopes supporting the trail to fail. The
trail has since been closed due to slope instability and public safety concerns. The purpose of the proposed project
is to stabilize the trail slopes, reopen the trail, and thereby reconnect a six-year closure of a Tier 1 Alignment of the
Regional Bicycle Transportation Network.
Aquatic Resources
Two wetland delineations were conducted within the project area. The first delineation was completed in August
2015.
The Second wetland delineation was completed in September 2019 to accommodate the proposed construction
limits in their entirety. The wetland delineations identified two wetland areas (0.49 acres) and one unnamed
stream channel within the project area (Figure 2).
The two wetland areas (Wetland 1, wetland 2) are incidental wetlands located within the ditch of the trail. Both
wetlands contained of three communities; shallow marsh, shrub-carr, and wet meadow. The shallow marsh
segment of the wetland is located on the northern end of the proposed access route. As the wetland extends
southwest, the slopes gradually increase causing the plant community to change from a shallow marsh to shrub-
carr and wet meadow. Using the Cowardin classification method the wetland areas were classified as palustrine
emergent wetlands that are partially seasonally flooded and temporarily flooded and ditched (PEMAd/PEMCd).
The unnamed stream was originally delineated as part of the 2015 wetland delineation report. The stream channel
was classified as a type 1 (RUBA) seasonally flooded sparsely vegetated stream channel.
Work conducted in Aquatic Resources
The proposed repairs will require work to be conducted within the two delineated wetlands and unnamed stream.
A constructed 10-foot wide access road is required along the existing trail to provide access for construction
materials and equipment. Portions of the trail corridor are too narrow and require placement of temporary fill in
the existing ditches (wetlands 1 and 2) to create the required 10-foot wide access route. Approximately 0.06 acres
of temporary fill will be placed within wetlands 1 and 2 (Appendix B, Pg G-05). Once construction is completed, the
fill will be removed and the ditches will be returned to as close to the pre-project existing conditions as possible.
Minnesota Interagency Water Resource Application Form February 2014 Page 5 of 15
The proposed repair work requires 0.025 acres (86 cubic yards) of riprap be placed within approximately 79 linear
feet of the existing stream channel. This portion of stream has been previously impacted due to installing riprap for
an emergency repair in 2016.
An additonal, 0.092 acres (64 cubic yards) of riprap will be placed below the ordinary high water level downstream
from the emergency repair area. The placement of this riprap will impact approximately 294 linear feet of stream
channel and help further protect the stream banks and prevent further bank erosion and sedimentation
downstream (Appendix B, pg C-13).
Schedule
Tree clearing would be completed in the spring of 2020. Construction is anticipated to begin in the summer/fall of
2020 and commence by the end of 2020.
Special considerations
Threatened and Endangered Species
A threatened and endangered species assessment was completed for the proposed project. The review identified
two federally listed species and five state listed species occurring within one-mile of the project area (Appendix
C).
Rare natural Communities
No records of rare natural communities are shown in the NHIS database within the project area.
Special Fish and Wildlife Resources
The project is expected to improve fish and wildlife habitat along the unnamed stream channel. The stream is an
intermittent stream and does not support fish populations. Stabilization of the adjacent slope and stream bank will
help improve downstream water quality by reducing the amount of sediment loading into the stream channel. The
project will not block or impede potential fish passage.
Cultural Resources
In 2015, a review of records at the Minnesota State Historic Preservation Office (MSHPO) was requested to identify
any previously recorded archaeological, historical, or architectural resources within the project area. Per the
Minnesota Archaeological Inventory and Historic Structures Inventory for the project area, no archaeological sites
were identified and one historic feature was identified within Section 25, T116N, R23W (Appendix D). This
property will not be affected by the proposed project.
In November 2019, a second record search was submitted to MSHPO for the expanded project area. No additional
cultural resources were identified.
Groundwater sensitivity
The project will not directly impact groundwater since excavations will occur up to 10 feet below the ground
surface.
Sensitive Surface Waters
The MDNR Pubilc Waters Inventory (PWI) did not identify any basins or watercourses within the Project area. No
sensitive surface waters such as impaired waterbodies or trout waters were identified within the project area.
Tree Removal
It is anticipated the proposed project will require tree removal around the north and south repair area. Large trees
will be avoided to the degree practical. Tree clearing will be conducted between November 1 and March 31 to limit
impacts to sensitive wildlife species. All trees removed with >6” dbh will be replaced in accordance with the City of
Chanhassen’s permit requirements (Appendix B, R-02).

Attachment A
Request for Delineation Review, Wetland Type Determination, or
Jurisdictional Determination
By submission of the enclosed wetland delineation report, I am requesting that the U.S. Army Corps of Engineers, St. Paul District
(Corps) and/or the Wetland Conservation Act Local Government Unit (LGU) provide me with the following (check all that apply):
Wetland Type Confirmation
Delineation Concurrence. Concurrence with a delineation is a written notification from the Corps and a decision from the LGU
concurring, not concurring, or commenting on the boundaries of the aquatic resources delineated on the property. Delineation
concurrences are generally valid for five years unless site conditions change. Under this request alone, the Corps will not address
the jurisdictional status of the aquatic resources on the property, only the boundaries of the resources within the review area
(including wetlands, tributaries, lakes, etc.).
Preliminary Jurisdictional Determination. A preliminary jurisdictional determination (PJD) is a non-binding written indication
from the Corps that waters, including wetlands, identified on a parcel may be waters of the United States. For purposes of
computation of impacts and compensatory mitigation requirements, a permit decision made on the basis of a PJD will treat all
waters and wetlands in the review area as if they are jurisdictional waters of the U.S. PJDs are advisory in nature and may not be
appealed.
Approved Jurisdictional Determination. An approved jurisdictional determination (AJD) is an official Corps determination that
jurisdictional waters of the United States are either present or absent on the property. AJDs can generally be relied upon by the
affected party for five years. An AJD may be appealed through the Corps administrative appeal process.
In order for the Corps and LGU to process your request, the wetland delineation must be prepared in accordance with the 1987
Corps of Engineers Wetland Delineation Manual, any approved Regional Supplements to the 1987 Manual, and the Guidelines for
Submitting Wetland Delineations in Minnesota (2013).

Supporting Information for Applications Involving Exemptions, No Loss
Determinations, and Activities Not Requiring Mitigation
Complete this part if you maintain that the identified aquatic resource impacts in Part Four do not require wetland
replacement/compensatory mitigation OR if you are seeking verification that the proposed water resource impacts are either
exempt from replacement or are not under CWA/WCA jurisdiction.
Identify the specific exemption or no-loss provision for which you believe your project or site qualifies:
WCA: 8420.0105 Subp. 2. D.
USACE: Nationwide Permit 13: Bank stabilization and Nationwide Permit 3: Maintenance
Provide a detailed explanation of how your project or site qualifies for the above. Be specific and provide and refer to attachments
and exhibits that support your contention. Applicants should refer to rules (e.g. WCA rules), guidance documents (e.g. BWSR
guidance, Corps guidance letters/public notices), and permit conditions (e.g. Corps General Permit conditions) to determine the
necessary information to support the application. Applicants are strongly encouraged to contact the WCA LGU and Corps Project
Manager prior to submitting an application if they are unsure of what type of information to provide:
WCA
Under 8420.0105 Subp. 2. D WCA does not regulate impacts to incidental wetlands. The two delineated wetlands that
would be temporarily impacted by the proposed project are manmade ditched wetlands. These ditches are meant to
convey water away from the trail. However, due to the lack of slope, water has ponded in the trail area creating a narrow
wetland within an upland area. The project will place approximately 0.06 acres of fill within the incidental wetland area.
This fill will be temporary and removed upon completion of the project. The ditches will then be restored to as close to the
pre-project existing conditions as possible.
USACE:
It is anticipated that work within Waters of the U.S. can be completed under Nationwide Permit 3 and/or Nationwide
Permit 13.
Maintenance Activities:
The proposed project would need to repair 0.025 acres (86 cubic yards) of riprap within approximately 79 linear feet of the
existing stream channel. Some riprap was originally placed in this segment of the stream channel as part of a previous
emergency repair needed to stabilize the south culvert outlet. Since then the riprap has been displaced during subsequent
flood and runoff events. The proposed project would salvage existing riprap and also install additional riprap to further
protect the area from future erosion.
Bank Stabilization Activities:
Bank stabilization activities necessary for erosion control or prevention, such as vegetative stabilization, bioengineering,
spills, riprap, revetment, gabion baskets, stream barbs, and bulkheads, or combination of bank stabilization techniques.
In order to stabilize the bank of the unnamed stream, 0.092 acres (64 cubic yards) of riprap will be placed below the
ordinary high water level. The placement of riprap will impact approximately 294 linear feet of stream channel.

roads, etc.), aquatic resource features (impact areas noted) and construction details (grading plans, storm water management
plans, etc.), referencing these as necessary:
Avoidance. Both the CWA and the WCA require that impacts to aquatic resources be avoided if practicable alternatives exist.
Clearly describe all on-site measures considered to avoid impacts to aquatic resources and discuss at least two project alternatives
that avoid all impacts to aquatic resources on the site. These alternatives may include alternative site plans, alternate sites, and/or
not doing the project. Alternatives should be feasible and prudent (see MN Rules 8420.0520 Subp. 2 C). Applicants are encouraged
to attach drawings and plans to support their analysis:
Minimization. Both the CWA and the WCA require that all unavoidable impacts to aquatic resources be minimized to the greatest
extent practicable. Discuss all features of the proposed project that have been modified to minimize the impacts to water
resources (see MN Rules 8420.0520 Subp. 4):
Off-Site Alternatives. An off-site alternatives analysis is not required for all permit applications. If you know that your proposal
will require an individual permit (standard permit or letter of permission) from the U.S. Army Corps of Engineers, you may be
required to provide an off-site alternatives analysis. The alternatives analysis is not required for a complete application but must
be provided during the review process in order for the Corps to complete the evaluation of your application and reach a final
decision. Applicants with questions about when an off-site alternatives analysis is required should contact their Corps Project
Manager.

Project Name and/or Number: HCRRA Minnesota River Bluffs LRT Regional Trail Slope Stabilization
Attachment A
Request for Delineation Review, Wetland Type Determination, or
Jurisdictional Determination
By submission of the enclosed wetland delineation report, I am requesting that the U.S. Army Corps of Engineers, St. Paul District
(Corps) and/or the Wetland Conservation Act Local Government Unit (LGU) provide me with the following (check all that apply):
Wetland Type Confirmation
Delineation Concurrence. Concurrence with a delineation is a written notification from the Corps and a decision from the LGU
concurring, not concurring, or commenting on the boundaries of the aquatic resources delineated on the property. Delineation
concurrences are generally valid for five years unless site conditions change. Under this request alone, the Corps will not address
the jurisdictional status of the aquatic resources on the property, only the boundaries of the resources within the review area
(including wetlands, tributaries, lakes, etc.).
Preliminary Jurisdictional Determination. A preliminary jurisdictional determination (PJD) is a non‐binding written indication
from the Corps that waters, including wetlands, identified on a parcel may be waters of the United States. For purposes of
computation of impacts and compensatory mitigation requirements, a permit decision made on the basis of a PJD will treat all
waters and wetlands in the review area as if they are jurisdictional waters of the U.S. PJDs are advisory in nature and may not be
appealed.
Approved Jurisdictional Determination. An approved jurisdictional determination (AJD) is an official Corps determination that
jurisdictional waters of the United States are either present or absent on the property. AJDs can generally be relied upon by the
affected party for five years. An AJD may be appealed through the Corps administrative appeal process.
In order for the Corps and LGU to process your request, the wetland delineation must be prepared in accordance with the 1987
Corps of Engineers Wetland Delineation Manual, any approved Regional Supplements to the 1987 Manual, and the Guidelines for
Submitting Wetland Delineations in Minnesota (2013).

From: Tyler Conley
Subject: Threatened and Endangered Species Review
Date: 12/05/2019
Project: Chanhassen Slope Failure Project
Barr Engineering Co. (Barr) has completed a threatened and endangered species desktop review for the
Hennepin County Regional Railroad Authority (HCRRRA) Slope Failure Project. The project area consists of
9.58 acres centered on the Minnesota River Bluffs LRT Regional Trail. Located within the City of
Chanhassen and City of Eden Prairie Minnesota, Section 23, T116W, R23N.
Federally listed species are protected by the federal government under the Endangered Species Act and
require consideration for projects involving federal permits. State listed species are protected under
Minnesota’s Endangered and Threatened Species Law and must be considered for state level permitting
requirements. The project area was reviewed for federal and state listed species and their associated
habitats that may be found in the project area. This desktop review was completed in November 2019
using a combination of data available from the United States Fish and Wildlife Service (USFWS) and the
Minnesota Department of Natural Resources (MNDNR).
1.1 Federally listed species
The USFWS Information, Planning, and Conservation System (IPaC) identified two federally listed species
as occurring within the project area, the northern long-eared bat (Myotis septentrionalis; federally
threatened) and the Rusty patched bumble bee (Bombus affinis; federally endangered). No designated
critical habitat for any federally listed species is located within the project area.
The northern long-eared bat inhabits caves, mines, and forests. According to the MNDNR, the nearest
hibernacula is over 6.7 miles southwest of the project area, and no maternity roost trees have been
identified within the vicinity of the project area. To minimize the potential impact on the species tree
clearing will be conducted between November 1 and March 31. Therefore, project clearing activites
completed prior to April 1, 2020 are anticipated to have no effect on northern long-eared bat.
Rusty patched bumble bees are typically found in grasslands with flowering plants from April through
October. They are typically nesting in underground and abandoned rodent cavities or clumps of grasses
above ground as nesting sites. During the winter months, queens typically overwinter in underground
cavities in upland forests dominated by maple-basswood or oak-hickory trees. The project area is
located within USFWS designated High Potentail Zone for the rusty patched bumble bee. The USFWS
Section 7 guidance recommends USFWS consultation for projects located within the High Potential zone.

1.2 State-listed species
Barr Engineering Co. (Barr) has a license agreement (LA-898) with the MNDNR for access to the Natural
Heritage Information System (NHIS) database, which was queried in November 2019 to determine if any
rare species could potentially be affected by the proposed Project. Two state-listed species have been
previously recorded within the project area; American ginseng (Panax quinquefolius), and smooth rock
cress (Boechera laevigata). In addition, the NHIS database identified five, state-endangered, threatened,
special concern or watchlist species have been documented within one mile of the proposed project area
(Table 1). Five native plant communities were also noted.
Table 1 Rare Species Documented within One Mile of Proposed Project Area According to
MNDNR NHIS
Common Name Scientific Name
Federal
Status State Status Habitat1
Kitten-tails Besseya bullii N/A Threatened
Primarily found in oak savanna communities, though it occurs in dry prairies and oak woodlands. Plants show a preference for partial to open light and upper slopes. Some populations exhibit a preference for less xeric north facing slopes in prairie habitats. Soils are most often sandy to gravelly, well-drained soil derived from alluvium or limestone.
Smooth Rock Cress Boechera laevigata N/A Special concern Found to occur on slopes in mesic deciduous forests.
Lark Sparrow Chondestes grammacus N/A Special concern Typically in dry short prairie grasslands in areas with sand or gravel spoils with some
bare ground and scattered trees.
American Ginseng Panax quinquefolius None Special concern Typically found in well-developed forest soil, mesic loamy soil.
Gophersnake Pituophis catenifer None Special concern Prefers well-drained, loose sandy and gravel soils.
1: Habitat information obtained from MDNR Rare Species Guide: https://www.dnr.state.mn.us/rsg/index.html
Kitten tails is the only state listed threatened species identified within one mile of the project area. Primary
habitat for the species consists of oak savanna communities on north facing slopes. No such habitat is
present within the project area. The majority of the project area is densely wooded deciduous forest with
a southeast facing slope. No dry prairie is present. Therefore it is unlikely for the species to be located
within the project area. The remaining state listed species are listed as species of special concern. These
species are monitored by the DNR but are not protected under state law.

c: Kristin Alstadt
As part of finalizing Task 2 and moving into final design, Task 3, the HCRRA (Hennepin County Regional
Rail Authority) and the Barr design team needed to understand the existence and extents of any wetlands
or fens within HCRRA right-of-way. This would include anything that would impact the design option
selected by HCRRA. A preliminary desktop review of the site was performed by Barr staff in February,
2015. A complete wetland delineation was recently performed June 17, 2015. A report summarizing the
preliminary and final wetland delineation findings was submitted to the HCRRA in July.
In addition to the wetland delineation, the Minnesota State Historical Preservation Office was contacted
by Barr staff to perform a database search for potential historical and archaeological resources within this
area of Section 25 and 36, of Township 116, Range 23 in the City of Chanhassen within Carver County.
According to the SHPO database, a historic feature (CR-CHC-049) is placed south of the landslide as
shown on Figure 1 (also attached).

The Historic feature is listed as a house (highlighted in yellow in Figure 2).
Figure 2. Historical/Architectural Inventory
To further investigate the potential for cultural resources within the project area or vicinity, Barr staff
scheduled a visit to the SHPO office to pull the file for this Inventory Number CR-CHC-049. Upon arriving
at the office, it was determined that a file had not been created for this inventory number as of the
afternoon of July 10, 2015. Julie Hillenbrand (a grant process facilitator at SHPO) left a voicemail with Barr
staff KNA the next morning on July 11, 2015 stating that their independent contractor who they hire to
create the files has not provided them with any documentation for this inventory number. Julie and Tom
Cinadr (property information/database searches at SHPO) both indicated that they had no idea when they
expected to receive files for this inventory number.
