FINDINGS OF FACT AND CONCLUSIONS
CENTRAL PARK COMMONS ENVIRONMENTAL ASSESSMENT WORKSHEET
EAGAN
DAKOTA COUNTY, MINNESOTA
I.
ADMINISTRATIVE BACKGROUND
The City of Eagan is the Responsible Governmental Unit for this project and CSM Eagan, LLC
LLC is the project proposer. An Environmental Assessment Worksheet (EAW) has been
prepared for this project in accordance with Minnesota Rules Chapter 4410. The EAW was
developed to assess the impacts of the project and other circumstances to determine if an
Environmental Impact Statement (EIS) is indicated.
The EAW was filed with the Minnesota EQB and circulated for review and comments to the
required EAW distribution list. A “Notice of Availability” was published in the EQB Monitor on
February 6, 2012. A Notice of Availability was sent to the Pioneer Press, Star Tribune, Eagan
This Week, Sun Current and Eagan Patch. These notices provided a brief description of the
project and information on where copies of the EAW were available, and invited the public to
provide comments that would be used in determining the need for an EIS for the proposed
project. The EAW was made available for public review at Eagan City Hall and the Dakota
County Library Wescott Branch in Eagan.
All comments received during the EAW comment period were considered in determining the
potential for significant environmental impacts. Comments received during the comment period,
and responses to the comments, are provided in Appendix A and B, respectively.

PROJECT DESCRIPTION
CSM Corporation proposes to redevelop the approximately 47-acre Lockheed Martin research
and development facility at Pilot Knob Road and Yankee Doodle Road in Eagan into a
development of either mixed office and commercial uses (Scenario A) or all commercial space
(Scenario B). The project is also referred to as the Central Park Commons Project.
The redevelopment will be a mix of large and small retail shops, restaurants, plaza spaces, and
trails. Scenario A would also include office space. Under Scenario A, the project will construct a
total of 75,000 square feet of office space and 480,500 square feet of open-air retail and
restaurant space. Under Scenario B, the project will construct a total of 507,600 square feet of
open-air retail and restaurant space. The project also includes construction of three stormwater
ponds and gateway signage at each entrance.
Corrections to the EAW or Changes in the Project Since the EAW was Published
Since the EAW was published, the following project items have changed or been updated:
Traffic
The EAW reported that the access along Pilot Knob Road at Norwest Court will remain open and
the existing Lockheed Martin driveway located across from Norwest Court will be closed.
Based on discussions with Dakota County staff, it is the County’s desire to modify this
intersection (i.e. median extension) to limit access to right-in/right-out movements in the future
to improve operations and safety along Pilot Knob Road. The City understands the County’s
long-term vision for this intersection but needs to develop other area connections to maintain
access for impacted properties before access modification can occur. Therefore, the City and
County will continue to monitor this intersection to determine the appropriate time for the access
modification and begin to investigate alternative roadway connections for impacted properties.
The EAW states that in order to safely accommodate the ¾ access for the proposed development
located between Norwest Court and Marice Drive, the Pilot Knob Road and Marice Drive
intersection needs to be modified to a ¾ access (restricting the westbound left-turn movement
from Marice Drive to Pilot Knob Road). This modification requires the median along Pilot Knob
Road to be extended at a minimum to Marice Drive. However, Dakota County staff expressed
concerns that stopping the median at Marice Drive will not completely restrict the potential for
illegal westbound left-turns from Marice Drive onto Pilot Knob Road. Therefore, it is the
County’s desire to extend the median along Pilot Knob Road through the Central Parkway
intersection to improve intersection safety. It should be noted that the County’s long-term vision
for the Pilot Knob Road and Marice Drive intersection would be a right-in/right-out only access.
The City and County realize the right-in/right-out modification is not currently necessary, but
will continue to monitor the intersection to determine if/when further access modification of the
Pilot Knob Road and Marice Drive intersection is required.

March 2012
Wastewater Generation
An updated calculation estimates the wastewater generated at the redeveloped site to be 71,000
gallons per day (gpd). The wastewater generation rate estimated in the EAW is 67,000 gpd.
Water Use
An updated calculation estimates the water use at the site to be 71,000 gpd. The water use
estimated in the EAW is 67,000 gpd.
Contamination
The EAW incorrectly noted that the property was formerly a Resource Control and Remediation
Agency site. The property was a Resource Conservation and Recovery Act site.
The EAW also noted that a Phase I Environmental Site Assessment (ESA) for the property did
not identify any evidence of contaminated soils. This should be corrected to state that the Phase I
ESA identified recognized environmental conditions, including above ground storage tanks,
sumps, and an oil-water separator. The Phase I ESA also identified historic recognized
environmental conditions, including former underground storage tanks, former manufacturing
operations, former wastewater treatment processes, and a closed leaking underground storage
tank site. The consultant recommended no additional soil investigations. The Minnesota
Pollution Control Agency (MPCA) advises that the purpose of a Phase I ESA is to document the
historical use for the property and does not analyze the soil or ground water contamination.
Asbestos is present in the existing building. The asbestos will be removed according to federal,
state, and county regulations including the Dakota County hazardous waste ordinance.
Metropolitan Council staff noted that the project is within the City of Eagan’s Drinking Water
Supply Management Area, which has been designated as having low to moderate vulnerability to
contamination by the City and the Minnesota Department of Health.
Wells
One well is known to be located on the site. In coordination with Dakota County, the well be left
in place until construction commences in 2013. The well will be sealed and closed at that time
according to MPCA, MN Department of Health, and Dakota County regulations.

DECISION REGARDING NEED FOR ENVIRONMENTAL IMPACT
STATEMENT
A.
Type, Extent, and Reversibility of Impacts
The City of Eagan finds that the analysis completed for the EAW is adequate to determine
whether the project has the potential for significant environmental effects.
The EAW described the type and extent of impacts anticipated to result from the proposed
project. This document provides clarifications and additional information since the EAW was
published. Following are the findings regarding potential environmental impacts of the proposed
project and the design features included to avoid, minimize, and mitigate these impacts:
Water Use
Dedication of sufficient public easement and access for the construction of a well and
transmission line pipe will be needed.
Stormwater Management
With the redevelopment, approximately 10 acres of impervious surface will be added to the site.
As part of the proposed redevelopment, the project will incorporate a stormwater management
plan designed to meet the permitting requirements of the City of Eagan (the administrator for the
Gun Club Lake Watershed Management Organization, or GCLWMO) and the MPCA (via the
National Pollutant Discharge Elimination System, or NPDES, permit). This management plan
along with the construction erosion and sediment control plan discussed below constitute the
stormwater pollution prevention plan as required by the NPDES permit. The permanent
stormwater management plan may include wet detention ponds and infiltration practices. It is
expected that the water quality and water quantity leaving the site will be improved over that of
the existing condition.
Temporary and permanent erosion control plans will be identified in the final site grading and
construction plans for each stage as required by the NPDES permitting for construction sites and
in accordance with local erosion/sedimentation standards. Erosion control measures will be in
place and maintained throughout the entire construction period. Removal of erosion measures
will not occur until all disturbed areas have been stabilized.
Wastewater
The project will connect to trunk and lateral municipal sanitary sewers that are available to the
north of the site. The site is served by Sanitary Sewer District N. The existing sanitary sewer can
accommodate wastewater from the site. A Sewer and Water Connection Permit will be needed
prior to construction.
Central Park Commons EAW
Findings of Fact and Conclusions

March 2012
Traffic
As discussed in EAW Item 21, access points along Pilot Knob Road will be managed for better
distribution of traffic volumes to and from the proposed site. However, to accommodate the
proposed ¾ access along Pilot Knob Road that will serve the proposed development, the
westbound left-turn movement at the Pilot Knob Road and Marice Drive intersection will be
restricted to maintain safe operations along Pilot Knob Road. The specific design of these access
points will be determined through the development approval process and coordination between
the City and Dakota County.
Land Use
The project is not currently compatible with the City of Eagan 2030 Comprehensive Plan land
use designation for this sub-area of the Central Commons Special Area. The proposer applied for
a Comprehensive Guide Plan Amendment, which the Eagan City Council approved for submittal
to the Metropolitan Council. As of December 28, 2011, the Metropolitan Council has waived
further review and action on the proposed amendment to change the land use designation of the
41.2 acre subject site to Major Retail.
B.
Cumulative Potential Effects of Related or Anticipated Future Projects
The area surrounding the project is fully developed and no substantial redevelopment activities
in the area are planned by the City. Therefore, there is little/no potential for significant
cumulative effects from the proposed project and other foreseeable future actions.
C.
Extent to Which the Environmental Effects are Subject to Mitigation by
Ongoing Public Regulatory Authority
The mitigation of environmental impacts will be designed and implemented in coordination with
regulatory agencies and will be subject to the plan approval and permitting process. Permits and
approvals that have been obtained or may be required prior to project construction include those
listed in Table 1.

Extent to Which Environmental Effects can be Anticipated and
Controlled as a Result of Other Environmental Studies
The City of Eagan and other regulatory agencies have extensive experience in redevelopment
projects. Many similar projects have been designed and constructed throughout the City with
similar environmental concerns. CSM Corporation has completed many redevelopment projects
throughout the Twin Cities area and have dealt with similar site constraints. All design and
construction staff are very familiar with the project area. No problem is anticipated which the
staff of CSM Eagan, LLC LLC or the City of Eagan have not encountered and successfully
solved many times in similar projects in or near the project area. The City of Eagan finds that the
environmental effects of the project can be anticipated and controlled as a result of
environmental review and experience on similar projects.

MnDOT Review # EAW12-002
Area NW of SB I-35E Exit ramp at Pilot Knob Road/Yankee Doodle Road
Eagan, Dakota County
Control Section 1982
Dear Mr. Ridley:
Thank you for the opportunity to review Central Park Commons Environmental Assessment
Worksheet. Please address the following comments before any further development:
1
Traffic: The EAW should include the impacts to the northbound I-35E to Pilot Knob ramp
terminal in its traffic operations analysis. MnDOT is concerned about potential queuing on the
exit.
For the North Ramp intersection of I-35E at Pilot Knob, the Synchro model outputs show Level
of Service (LOS) E (Existing through 2015 build) and LOS F for the 2030 options. However, the
SimTraffic outputs show that this intersection is operating at LOS B (Existing through 2015
build) and at LOS C for the 2030 options. The poor Synchro LOS seems to be due to a heavy
eastbound to southbound right-turn movement. This may need more investigation. Please
identify the reason for the discrepancy between the Synchro output and the SimTraffic.
Please submit the Synchro files for review. Please submit to David Sheen, MnDOT Metro District
Traffic (651-234-7824 or David.Sheen@state.mn.us).
Review Submittal Options:
Mn/DOT’s goal is to complete the review of plans within 30 days. Submittals sent in
electronically can usually be turned around faster. There are four submittal options. Please

This document summarizes the review finding comments related to the Lockheed Martin Site
Redevelopment Traffic Analysis.
An initial review of a “high level assessment” was conducted in August 2011. That information
suggested the traffic expected from this site will have a significant impact on the county highway system
in an area already having capacity and operational concerns. Since that time SRF traffic staff worked
with the county to identify the revised development plan impact along with best analytical practice for
reducing traffic based on the existing Lockheed Martin sight use. Those interim review steps showed the
AM traffic had a relatively minor impact to the system so conducting only a PM evaluation focusing more
directly around the sight would provide the necessary understanding of the operation with the proposed
development.
The staging of review has allowed interim review comments to be incorporated into the process and
provided an opportunity for modifications internal to the site to address some traffic flow concerns. The
evaluation includes the necessary assessments and traffic analysis approach is consistent with standard
methods.
The following are comments related to the report along with some thoughts and direction for further
discussion between the city and county for access and improvements in the area:
1
x
Traffic Safety -- A collision assessment was not included in the traffic study. While typically
traffic impact analysis does not review the collision information, this data should be considered in
the overall environmental impacts and during discussions of access and median operation for the
corridor of Pilot Knob and Yankee Doodle.
x
Area Needs - Past correspondence noted the long-rang needs and access plans for Yankee
Doodle and Pilot Knob Road. The study and especially 2030 access plans could be reflected
more fully in the study analysis to recognize the development impact and just overall traffic
changes necessitating access and operational changes through the area. Specific items include:
CSAH 28, Yankee Doodle Road has a 6-lane need in this area which would necessitate ½ mile
full access spacing. The main access for the development off of Central Parkway is seen as a full
access long term and the intersection of Washington Avenue with CSAH 28 is an existing signal
approximately 1/8 mile from Pilot Knob Road that is too close to other major intersections and
creates operational issues along the corridor. The development has little impact on this
operation so that long-term need and evaluation will be handled outside this study.
2
Pilot Knob Road (CSAH 31) has a 6-lane divided highway need from Diffley Road to Central
Parkway with ½ mile full access corridor adjacent to the proposed redevelopment site and north
of Central Parkway. As noted in earlier reviews, additional access through the area would only
be considered based on county staff determination that an evaluation indicates additional access
would benefit the highway system. Issues related to evaluations along Pilot Knob Road include:

Traffic Impact Analysis Review Comments

Page 2 of 2
o
Proposed development access along Pilot Knob Rd. reduces some traffic using the signal
at Central Parkway and Yankee Doodle and provides a 2nd option for northbound left turns
into the site. This access is beneficial however, the expectation that the majority of left
turns would occur at this partial access may not be reflective of actual conditions. The
Central Parkway access is restricted in order to provide for a turn at Maurice which is
accommodating a minor move that could be served at the traffic signal. Additionally,
other turn movements are being provided with potentially less than adequate deceleration
and storage areas. In reviewing the operations and access schematic, turn lane tapers and
lengths may need to be longer than shown to facilitate proper access throughout area.
Figure 7 is viewed as a schematic for discussion of the possible access configuration. A
partial access along Pilot Knob for the development is beneficial and should be
developed; the details of the median extension, left turn lane needs throughout the
area along Pilot Knob Road, and location of each median closures and specifics to go
along with this access proposal for the development will need to be worked out
between the county, city and developer through design.
o
The study identifies that the Pilot Knob Road and Norwest Court access operations fails
for traffic exiting Norwest. While an interim plan for access in 2015 should be discussed
with the city including opportunities to provide a connection to the signal at Northwood
Parkway, the 2030 access scenario should provide for the right in-out access at Norwest
Court as the issues here are related not only to queuing southbound Pilot Knob but lack of
ability to find gaps and safety issues. 2030 evaluation should show this access as right
in/out to recognize the necessary improvement based on operations and the long term
plan based not only on spacing guidelines but evaluation findings and safety.

Improvement Measures:
5
6
The traffic study identifies that the Central Parkway and development access at Quarry Road access
operations fails for traffic exiting the development. Study notes “this intersection should be monitored to
determine if/when a traffic signal or roundabout may be needed.” Potential solutions and how
improvements could be accommodated (right of way needs etc...) in the future is an item that would
typically be discussed with the city through this study and development review process.
Study recommends a partial access along Pilot Knob Road to provide for better distribution of traffic
volumes. The study does show how this distribution would be beneficial to the street system. The exact
design needs for Pilot Knob Road including median changes, openings, and signal improvements at
Central Parkway and Pilot Knob Road will need to be worked out through discussions with all
parties and additional design work.
The implementation of timing changes and other intersection improvements identified through the
report will also need to be discussed and agreements/permits developed to facilitate implementation
as applicable.
Based on review, next steps should be discussion on implementation. Corrections could take place
to reflect comments in the environmental work as applicable.

Responses
Minnesota State Historic Preservation Office
1. Response: Comment noted.
Minnesota Department of Natural Resources
1. Response: Comment noted.
Minnesota Pollution Control Agency
1. Response: The MPCA Sanitary Sewer Extension Permit has been added to the updated
Permit Table under Item C.
2. Response: The wastewater generation rate projection was based on the proposed building
square footages and the Metropolitan Council Sanitary Sewer Availability Charge Schedule. The
projections were based on the both scenarios (all retail and restaurant, or including office uses as
well). Based on the City’s 2030 Comprehensive Sewer Plan
(http://www.cityofeagan.com/upload/images/PublicWorks/Eng/RSCP%20CompSewer.pdf),
retail land uses are expected to generate approximately 1,000 gallons per acre per day, with a
peak flow factor of 1.5, or 1,500 gallons per acre per day. If this rate is applied to all 47.3 acres
of the site, the rate per day is 71,000 gpd. City staff find that the existing municipal wastewater
conveyance system has sufficient capacity to handle this volume of wastewater.
3. Response: Correction noted. This information was added to Section II of this document.
4. Response: Correction noted. This information was added to Section II of this document.
5. Response: CSM Eagan, LLC LLC acknowledges the possibility of encountering
contaminated soils on the project site, though the developer is not aware of existing
contaminated soils on site at this time. Asbestos is present in the existing building, and removal
will occur prior to building demolition. All contaminated soils and materials will be handled and
disposed of according to federal, state, and county regulations. The possibility of contaminated
soils will be taken into account when selecting stormwater infiltration methods.
6. Response: CSM Eagan, LLC LLC will utilize stormwater management methods to meet the
City’s stormwater management ordinance. Best management practices may include rate control
ponds, wet detention ponds, and infiltration practices. The on-site BMPs in conjunction with
ponding facilities downstream of the site will help to minimize any water quality impacts to
receiving waters.
Minnesota Department of Transportation
1. The I-35E northbound off-ramp/Pilot Knob Road intersection was included in the initial
review of the traffic operations analysis. However, after reviewing the associated trip generation
of the proposed development, and taking into account traffic pattern shifts due to the recently
opened Duckwood Drive overpass and the existing Lockheed Martin traffic, the impact at the
I-35E northbound off-ramp/Pilot Knob Road intersection was minimal. Once this was
determined, the development team (SRF, City of Eagan, and Dakota County traffic staff) agreed
that there was no significant need to continue to analyze this intersection.
Based on discussions with MnDOT staff, the main queuing concerns in this location are
specifically during the a.m. peak hour. It should be noted that traffic volumes on the I-35E
northbound off-ramp during the p.m. peak hour are significantly lower than the a.m. peak hour.
Since the proposed development will consist of mainly retail land uses, which are replacing an
office land use, the volume impact during the a.m. peak hour will be less than what currently
exists (see Table 3A in Appendix D). Therefore, queuing on the northbound I-35E off-ramp
during the a.m. peak hour will not be impacted by the proposed development.
MnDOT staff was provided additional information about the discrepancy between the Synchro
and SimTraffic output. Synchro is a macroscopic model that looks at each individual intersection
from a capacity perspective. SimTraffic is a microscopic model that takes into account various
driver characteristics and the impact of adjacent intersections. The SimTraffic results provided a
more realistic representation of the traffic operations that were observed at this location. Synchro
has difficulty modeling this eastbound right-turn movement due to gaps in the southbound traffic
flow along Pilot Knob Road created from the signal at the Pilot Knob Road/Yankee Doodle
Road intersection, as well as the slightly higher turning speeds due to the eastbound channelized
right-turn lane. Therefore, results from SimTraffic were reported for this location based on
engineering judgment. It should be noted that both the Synchro and SimTraffic outputs were
included in the appendix at the request of Dakota County.
The development team has coordinated with MnDOT staff and provided the files as requested.
Metropolitan Council
1. Response: Comment noted.
2. Response: The 2008 Water Supply and Distribution Plan and the 2007 Emergency and
Conservation Plan both addressed the future demand of a fully developed Eagan, including the
full development of the project site. The additional demand of the 67,000 gallons per day
reported in the EAW is well within the scope of these plans, as is the corrected estimate of
71,000 gpd reported in Section II of this document. The project site demand may be addressed
without utilization of the on-site future supply well.
3. Response: Comment noted. This information was added to Section II of this document.
4. Response: The stormwater management design will consider the contamination potential.
5. Response: The City of Eagan will evaluate the water conservation measures as part of the
development review process. The City will encourage CSM Eagan, LLC to implement water
conservation on the site.
6. Response: The site plan indicates sidewalks throughout the site. A transit station is located
approximately ¼ mile southeast of the project site. Pedestrian access to the transit station and bus
stops along Pilot Knob and Yankee Doodle Road will be provided. No deviation of service is
proposed.
7. Response: Bus stops are located along Pilot Knob Road (approximately every 0.2 mile) and
Yankee Doodle Road (approximately every 0.1 mile). The site will include good pedestrian
access, which increases the value of the site for transit use.
8. Response: Comment noted. The City will amend its Comprehensive Plan to show the change
to the land use map.
Dakota County – Lynn Thompson
1. Response: See Section II of this document for changes in the proposed access design
coordinated with Dakota County since the EAW was published.
The additional safety data is noted. The City of Eagan will continue to work with Dakota County
to monitor safety problems and coordinate resolving any issues that arise.
2. Response: The footprint for a potential roundabout at the Quarry Drive and Central Parkway
intersection has been accommodated into the site design (i.e. building setbacks, etc).
3. Response: CSM Eagan, LLC LLC is not aware of existing contaminated soils on the site.
Any hazardous waste generated or contaminated materials encountered on the site will be
handled according to federal, state, and county regulations.
4. Response: The asbestos removal will be handled according to Dakota County regulations
(see Response #5).
5. Response: All waste disposal, including demolition materials, industrial waste, or
construction waste will occur in accordance with the Dakota County Solid Waste Ordinance, and
Hazardous Waste Regulation ordinance.
6. Response: Comment noted. The well present on the property will be sealed and closed
according to Dakota County regulations.
7. Response: Previous site cleanup activities included groundwater testing. In 1994 a petroleum
release occurred and cleanup was done in coordination with the MPCA involving excavation and
removal of 11 drums of soil. Additional soil and groundwater testing was conducted to the
satisfaction of the MPCA. The leak site was closed in 1995.
A RCRA investigation conducted at the site detected chromium in the groundwater. Additional
investigation was required by the MPCA to determine if a release had occurred. The
investigation was conducted and concluded that a release had not occurred and that the
chromium was naturally occurring in the groundwater. The MPCA agreed with these findings in
a letter dated December 2, 1993. All of the monitoring wells were removed under the MPCA
direction.
8. Response: CSM Eagan, LLC LLC will utilize stormwater management methods to meet the
City’s stormwater management ordinance. The development review process will review the
stormwater management practices proposed on the site, and will encourage the developer to
utilize low impact development practices. Best management practices may include rate control
ponds, wet detention ponds, and infiltration practices. The on-site BMPs in conjunction with
ponding facilities downstream of the site will help to minimize any water quality impacts to
receiving waters.
Dakota County – Kristi Sebastian
1. Response: The additional safety data is noted. The City of Eagan will continue to work with
Dakota County to monitor safety problems and coordinate resolving any issues that arise. See
Section II of this document for changes in the proposed access design coordinated with Dakota
County since the EAW was published.
2. Response: The City of Eagan will continue to work with Dakota County to monitor capacity,
access, and safety issues within the study area and coordinate resolving any issues that arise.
3. Response: See Section II of this document for changes in the proposed access design
coordinated with Dakota County since the EAW was published.
4. Response: See Section II of this document for changes in the proposed access design
coordinated with Dakota County since the EAW was published.
5. Response: The footprint for a potential roundabout at the Quarry Drive and Central Parkway
intersection has been accommodated into the site design (i.e. building setbacks, etc).
6. Response: See previous responses and Section II of this document for a description of
changes in the design since the EAW was published.
