ISSUE
The City of Rosemount, Empire Township, and the University of Minnesota are cooperating on an
alternative urban areawide review (AUAR) for the 5,000 acre UMore Park. Over the year, City staff
and consultants (along with Empire Township and UMore staff and their consultants) have created
the draft UMore AUAR, which completed its 30 day comment period on July 10. The City received
nine responses, seven from various agencies and two from citizens. The seven agencies that
responded were Dakota County, the Metropolitan Council, the Minnesota Department of Agriculture,
Department of Health, Department of Natural Resources, Pollution Control Agency, and Department
of Transportation. Neither of the citizens who commented are Rosemount residents. Martha
Henderson is a resident of Inver Grove Heights. Ronald Spong is a resident of St. Paul and a former
Dakota County Environmental Management employee.
Dakota County
Dakota County submitted comments regarding transportation and environmental resources. Many of
the transportation comments are for the City's use during Comprehensive plan review for UMore.
Many of the environmental resources comments will be addressed more specifically during or directly
before Preliminary Plat review. There was one comment regarding greenways that was already
addressed in the AUAR.
Metropolitan Council
The Metropolitan Council provided comments regarding land use forecasts, water supply, surface
water management, wastewater, and transportation. The land use forecasts, surface water and water
supply comments are about issues that the City has on -going involvement with the Met Council or
other agencies. Transportation comments are similar to those provided by Dakota County and
MnDOT.
Staff has discussed wastewater planning with Met Council's staff. In the foreseeable future,
Rosemount and UMore wastewater will flow to the Empire Wastewater plant. Met Council staff
stated that their long range plans include the possibility of retrofitting the Rosemount wastewater
treatment plant to serve east (and possibly central) Rosemount.
Minnesota Department ofAgriculture
The Department of Agriculture stated that they have no comments.
Minnesota Department ofHealth
The Department of Health provided broad comment topics (including affordable housing, energy
consumption, health impact assessments and physical activity) and again mentioned the groundwater
comments provided during gravel mining permitting. Staff provided an update on the gravel mining
permit, but did not include those permit conditions in the AUAR because the AUAR is based on
mining activity being completed and the lands reclaimed.
Minnesota Department ofNatural Resources
The DNR ask that prior to development of UMore their databases be reviewed and also reminded the
City what permits are required from the DNR.
Minnesota Pollution Control Agency
The PCA comments included surface water and remediation programs. Staff responded that the
City's stormwater regulations reduce run -off as compared to the current condition. Several issues
about site remediation noted which will be addressed more completely during or immediately before
Preliminary Plat review of new developments.
Minnesota Department of Transportation
The MnDOT comments are similar to the Dakota County and Met Council comments. All the
comments included references to the regional traffic model. The traffic information from the AUAR
will be added to the regional model during the decennial Comprehensive Plan creation.
Ronald Spong
Ronald Spong is a St. Paul resident and a former Dakota County Environmental Management
employee. Many of his comments are regarding contamination at the UMore property. His concerns
are addressed through the comments provided previously for Dakota County, Metropolitan Council,
Department of Health and the Pollution Control Agency.
Martha Henderson
Martha Henderson is an Inver Grove Heights resident who attended the AUAR Open House and
provided a comment letter that requested that no development occur on the UMore property and that
the area should be returned to its natural state for wildlife habitat. Staff responded that about 1,000
acres (about 20 %) of the UMore property is designated for open space and that Vermillion Highlands
and Whitetail Woods Park is located directly south of UMore.
Tentative Remaining A UAR Review Schedule
Sept. 3 thru 13: 10 Day Comment Period
September 24: Planning Commission Recommendation
October 15: City Council Approval
2
The University of Minnesota and Empire Township will be conducting a similar review of the AUAR,
but the City is the responsible government unit (RGU) and ultimately will be the final authority on the
AUAR.
RECOMMENDATION
Review the comments received and provide comments on the proposed responses.

2 1 Alternative Urban Areawide Review - UMORE Study Area
July 2013
Dakota County UMore Alternative Urban Areawide Review (AUAR) Comments:
1. Transportation
a. Page 8, Section II. Executive Summary, vii. Transportation Mitigation Plan, Section B.:
The County's existing Plat Review Needs map only indicates a need for a four -lane
divided highway in the future for CSAH 42. However, this need was based on the
existing County travel demand model that does not include traffic analysis information
for the UMore site. Therefore, it is reasonable to assume that the County's model and
plat review needs will reflect a 6 -lane need in the future. The County's guidelines
require 100' of half right -of -way for 6 -lane facilities.
b. Page 8, Section II. Executive Summary, vii. Transportation Mitigation Plan, Section F:
Consider revising the mitigating statement should as, "Provide right -of -way required for
future roadway expansion adjacent and within the UMore property."
c. Future access locations to CSAH 42 are limited to %: mile interval spacing and /or in
accordance with the CSAH 42 Study recommendations and amendments.
d. The document should incorporate text confirming that roundabouts are a potential
intersection control measure and identify the traffic volume threshold they can be
considered (similar to what is listed for interchange and signal alternatives in the Access
and Intersection Control section).
e. This development will have large scale impacts to the county and supporting local
roadway system beyond the intersections assessed In this AUAR. It can be expected
that the county road system /intersections beyond the limits covered here will need
analysis of impacts as development is further identified and /or occurs.
f. Non - comments / General Observations - In all three of their scenarios, the future
alignments for 160`h St W (CSAH 46), Akron Avenue (CSAH 73) and CSAH 71 appear to be
consistent with recommendations of the Rosemount / Empire / UMore Area
Transportation System Study. It appears only the future land use designations in some
locations differ by designation.
2. Greenways
a. The AUAR correctly describes the Vermillion Highlands Greenway that runs north /south
through the UMORE property, generally between Dakota County Technical College and
Whitetail Woods Regional Park. For purposes of clarity, please include the attached
map from the adopted Vermillion Highlands Greenway Master Plan in the AUAR
document.
3. Environmental Resources
a. County Staff recommends a comprehensive approach be taken to offset future clean up
and site restoration expenses before the UMore property is parceled, sold and
developed.
3 1 Alternative Urban Areawide Review - WORE Study Area
July 2013
b. Page 1, Section I. Executive Summary, i. Introduction /Background: The UMore Study
Area is located on the grounds of the former Gopher Ordnance Works, a privately -
owned (i.e. non - federal) Formerly Used Defense Site (FURS), as defined by the March
21, 2002, U.S. Environmental Protection Agency Policy Towards Privately -Owned
Formerly Used Defense Sites. "This policy contemplates that most response actions and
cleanup activities at privately -own, non -NPL FUDS will be conducted under the Defense
Environmental Restoration Program (DERP) and Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA)." The Minnesota Pollution Control
Agency has stated in correspondence to the United States Army Corps of Engineers
(USACE) and the University of Minnesota (letters dated December 4, 2009; January 30,
2009; and August 11, 2008) that a "full and completed Remedial Investigation /Feasibility
Study (RI /FS) is necessary for the entire GOW site," which includes "an evaluation of the
potential threats to the public from physical hazards and asbestos containing debris at
the GOW site." Compliance with the FUDS manual may also be required.
The AUAR anticipates that "... most, if not all of development within the study
area will be undertaken by private entities, not the University of Minnesota,
pursuant to land sales or ground leases." However, the City of Rosemount is
expected to acquire and develop approximately 209 of the project area for
public infrastructure and services. Prior to property transfers, due diligence
should be exercised to investigate and remediate individual areas in accordance
with their previous land uses, and reasonable and appropriate actions taken to
protect public health and the environment from releases.
c. Page 5, Section III. Summary of Mitigation Measures, ii. Water Use Mitigation Plan, D:
This section indicates that abandoned wells found within the study area will be sealed in
accordance with Minnesota Department of Health guidelines. Dakota County has
delegated responsibility for wells within the county. Therefore, all abandoned wells
must be sealed in accordance with Dakota County Ordinance No. 114, "Well and Water
Supply Management ", in addition to MDH guidelines.
d. Page 5, Section II. Summary of Mitigation Measures, ii. Water Use Mitigation Plan, E:
According to a letter dated July 25, 2012 from the Minnesota Department of Health to
the Rosemount City Engineer, the mine -pit lake (referred to in the AUAR as Lake 2162)
created by gravel extraction below the water table will be hydraulically connected to the
bedrock aquifer up- gradient of the Rosemount municipal wells. Furthermore, the
mine -pit lake will be located within a highly vulnerable portion of the City's drinking
water supply management areas (DWSMA); meaning that the aquifer may be impacted
by activities at the ground surface and that Lake 2162 could be a direct conduit for
contamination into the aquifer. As a result, measures should be planned to protect Lake
2162 from potential contamination.
e. Page 18, Section 111. UMORE Study Area AUAR, 9.1-and Use. A. Existing Land Use: This
section contains no mention of existing tenants at the UMORE site that generate
hazardous waste or have the potential to cause contamination (e.g. Reese Enterprises —
Astro Plastics Division, Bomb Squad demolition /training site). The descriptions of the
investigations that have been conducted provide sufficient evidence that contamination
4 1 Alternative Urban Areawide Review - UMORE Study Area
July 2013
exists on the old GOW site and other former tenant sites. Environmental conditions
from past land uses vary widely across the UMore Study Area. Based on historical land
use, hazardous materials that may be present include asbestos, arsenic, gunpowder,
lead, petroleum products, PCBs, mercury, SVOC's, and other contaminants (see section
111, 9, F).
Pages 20 -21. Section Ill. UMORE Study Area AUAR, 9. Land Use, E. Superfund Site
Status: Although the 2011 -2012 Five Year Review of the NPL sites at UMORE found the
response actions protective of human health and the environment, the finding was
explicitly based on current land use. This determination should be re- evaluated with
any change of land use, such as those proposed in the AUAR. In addition, the Five Year
Review did call for improved access controls, such as fencing, to limit public exposure to
the significant physical hazards (broken concrete, protruding rebar, pits, trenches,
tunnels, and others) present at the site.
g. Pages 39 -51. Section III. UMORE Study Area AUAR, 13. Water Use, A. Existing
Conditions: Prior to 1974, well records for newly installed water supplies were not
required to be submitted to the state of Minnesota. As a result, the number of wells in
use or abandoned within the study area may be much greater than the records available
for review in the County Well Index (CWI). Dakota County Groundwater Protection staff
have been working with University of Minnesota staff to create an inventory of known
and suspected wells within the study area.
Water Use, Scenarios 1 -3: Groundwater is proposed as the source of the
community's water supply, but groundwater may not be an adequate or
feasible long -term water source. The Metropolitan Council's 2010 Metro Area
Water Supply Plan, Appendix 2 (Community Water Supply Profiles), projected
growth in maximum daily use for the City of Rosemount from 8.5 million GPD in
2010 to 29.6 million GPD in 2050. This projection did not include the planned
UMore development. That level of demand for the City of Rosemount as a
whole resulted in projections for a "potential for significant decline in aquifer
water levels," with a "predicted decline in available head greater than 50% in
confined portions of the Prairie du Chien- Jordan aquifer under projected 2030
demand conditions."
1. On the other hand, the AUAR states that "UMore development would
result in 3.64 MG of additional storage needs," 2.5 MG of storage more
than anticipated in the City of Rosemount's 2007 Comprehensive Water
Plan (AUAR, p. 43). The AUAR's estimates of future need are not as high
as the Metro Area Water Supply Plan: "The City's total maximum day
demand upon complete development of the study area would 18.24
MGD (12,664 gpm) and average day of 6.078 MGD (4,221 gpm)."
Regardless of which projection (29.6 million GPD or 18.24 million GPD)
proves more accurate, the City of Rosemount will need to monitor
groundwater, climate, and population trends and evaluate its options
for providing water for future growth.

Management Districts: Any alterations to Shoreland in Empire Township must be
conducted in accordance with Dakota County Ordinance No. 50, " Shoreland and
Floodplain Management ".
i. Pages 73 -74, Section III. UMORE Study Area AUAR, 19. Geologic Hazards and Soil
Conditions, C. iii. Scenarios 1, 2 and 3: The AUAR states, "Commercial and industrial
uses are anticipated to be clean uses" and "... the potential for groundwater
contamination and /or adjacent drinking well contamination should be no greater than,
and is expected to be less than, the potential that exists with the existing agricultural
land use." Commercial and industrial activities may be subject to County regulation of
solid and hazardous wastes, in addition to federal and state regulations.
j. Page 74, Section 111. UMORE Study Area AUAR, 19. Geologic Hazards and Soil
Conditions, C. iv. Geologic Hazards and Soil Conditions Mitigation Measures: This
section lists construction site Stormwater Pollution prevention Plans as a mitigation
measure. Due to the history of the study area, reliance on construction NPDES and
contingency plans may not be sufficient to identify hazardous substances that might be
disturbed during construction activities. Priorto any excavation or other land- disturbing
activities, due diligence should be exercised to investigate and remediate individual
areas in accordance with their previous land uses, and reasonable and appropriate
actions taken to protect public health and the environment from releases.

RE: UMore Park Draft Alternative Urban Areawide Review
Metropolitan Council Review File No. 21138 -1
Metropolitan Council District 16, Wendy Wulff
Dear Mr. Zweber:
Metropolitan Council staff completed its review of the UMore Park Alternative Urban Areawide Review
(AUAR) to determine its accuracy and completeness in addressing regional concerns. While the AUAR
covers land in both the City of Rosemount (City) and Empire Township (Township), the City is the
Responsible Governmental Unit.
Staff concludes that the updated AUAR is complete and accurate with respect to regional concerns and raises
no major issues of consistency with Council policies. However, staff offers the following comments:
Item 8 — Permits and Approvals
In accordance with Minnesota Statute Section 473.513, at the time the City makes application to the
Minnesota Pollution Control Agency (MPCA) for a permit to construct each segment of sanitary sewer
for the proposed project, a copy of the plans, design data, and a location map of the project will also need
to be submitted to the Metropolitan Council. The Council's Environmental Service Municipal Services
staff will need to review, comment, and recommend issuance of the construction permit by the MPCA
before connection can be made to the City's wastewater disposal system.
Item 9 — Land Use
The AUAR presents three scenarios involving major development initiative on the UMore Park site (7.7
square miles). Scenario I represents a "village" build -out scenario with housing for 34,500 population and
employment- supporting zones for 18,200 jobs. Scenario 2 represents a lower- density "village" build -out
scenario with housing for 25,300 population and employment- supporting zones for 18,200 jobs. Scenario
3 represents a higher employment build -out scenario with housing for 31,400 population and
employment - supporting zones for 24,500 jobs.
Most of this development is expected after 2030 (the AUAR says 2028) and anticipates growth beyond
the scope of the City's 2030 Comprehensive Plan.
Council Staff believe that the build -out targets described might be staged over a 20 or 30 year period
extending to 2050 or 2060. At this time the Council has not established forecasts for 2040, 2050 or 2060.
If this development is incorporated into the City's and Township's Comprehensive Plan Updates for 2040,
then staff can discuss appropriate population, household and employment forecasts in the context of
growth in surrounding areas and regional growth including provisions for the City's share of the region's
affordable housing need.

Regional Parks: The UMore Park area is located near two planned regional parks system facilities, both of
which are acknowledged in the AUAR. The planned Whitetail Woods Regional Park is located
immediately south of UMore Park, and the planned Vermillion Highlands Greenway Regional Trail
traverses the UMore Park site. The Metropolitan Council approved the alignment of the Vermillion
Highlands Greenway Regional Trail in November 2012 as part of Dakota County's master plan for the
regional trail.
All of the development scenarios in the AUAR include an open space greenway to accommodate the
regional trail, which will connect Lebanon Hills Regional Park to Whitetail Woods Regional Park.
Council staff encourages the University of Minnesota, the City of Rosemount and Empire Township to
work with Dakota County to facilitate development of the regional trail.
Item 13 — Water Supply
Water supply is a critical factor in future growth planning. The Council has significant concerns about
the expansion of groundwater use in the UMore Park AUAR area in Dakota County.
Council research of long -term ground water use indicates considerable decline in available groundwater
in the UMore Park area. This is modeled to in the year 2030. The proposed development of UMore Park
and continued reliance on groundwater sources puts pressure on existing aquifer supplies.
In 2013, the Council has been working with communities around the region generally and specifically
with engineers from cities in Dakota County to address the greater water supply issue. The City and
Township should continue to work with Council Staff as groundwater modeling is refined and alternate
sources for water supply are explored.
Council research reveals moderate and high potential recharge to the aquifer; future development should
include the latest infiltration across all land uses.
Item 17 — Water Quality — Surface Water Runoff
The National Weather Service's Hydrometeorological Design Studies Center recently released new
precipitation frequency estimates for many of the Midwestern states, including Minnesota, in a
publication termed the NOAA Atlas 14 Point Precipitation Frequency Estimates. (See
http://www.dnr.state.mn.us/climate/noaa atlas 14.htm1 and
http://hdsc,nws.noaa.gov/hdsc/�fds/pfds man cont html ?bkmrk =mn )
The new estimates result in generally higher projected rainfall events for the average 50- and 100 -year
recurrence intervals. The AUAR does not indicate what amount of rainfall was utilized for the 100 -year
event, but the new Atlas 14 precipitation frequency data estimates indicate that future 100 -year rainfall
recurrence interval events should now be estimated to be approximately 7.4 ". These new data should be
utilized in the calculation of runoff to properly size the proposed project's stormwater conveyance,
treatment, and infiltration facilities.
Mr. Eric Zweber
July 9, 2013
page 3
Item 18 — Wastewater
The AUAR redefines the individual sanitary sewer districts within the project area from those previously
identified in the City's 2008 Comprehensive Plan Update. The AUAR currently calls for the area to be
served through four (4) primary districts — the East District, Central District, Northwest District, and the
Southwest District — with each having its own separate connection to the regional wastewater system. The
regional interceptor system that provides service to this area of the City was designed and constructed
with specific capacities. During its review of the City's 2008 Update, the Council met with the City to
discuss the system capacity within the regional system and the City committed to finalizing a wastewater
plan that would be consistent with the assigned capacities of the regional system.
The service area map included in the AUAR shows larger areas being served through the upstream
portion of the regional system where system capacity is less. This represents a potential system impact if
long term flows from these areas exceed system capacity. That portion of the gravity interceptor
downstream of L75 (Biscayne Avenue) has sufficient capacity to serve the City including the AUAR
project area.
The City will need to update its Comprehensive Plan, including its Tier II Comprehensive Sewer Plan,
prior to the installation of any sanitary sewer improvements within the AUAR project area. The approved
Tier II Comprehensive Sewer Plan will need to reflect that long term cumulative wastewater projections
from each service district connection point is consistent with the assigned regional capacity. This will
more than likely require that portions of the East, Central, and Northwest service district be directed west
toward that portion of the system within Biscayne Avenue.
Item 21— Traffic Forecasts and Transportation Mitigation
The use of ITE trip generation rates for calculating traffic impacts for a development this large is
inappropriate. The unreasonably high nature of trip generation estimates calls into question the
expansion needs identified in the AUAR which include expanding CSAH 42 from four -lanes to six,
constructing an interchange to replace the existing TH 3 /CSAH 42 intersection and reconstructing the
existing interchange at CSAH 42 and US 52.
It should also be noted that CSAH 42 and CSAH 52 are principal arterials and hence part of the
metropolitan highway system. The 2030 regional Transportation Policy Plan does not include any of the
described improvements to these metropolitan highways. Construction or reconstruction of the
interchanges and expansion of CR 42 would need controlled access approval from the Metropolitan
Council. The city of Rosemount should continue to coordinate with MnDOT and the Metropolitan
Council regarding any proposed changes to the metropolitan highway system.
Item 27 — Compatibility with Plans and Land Use Regulations:
The Metropolitan Council is drafting a new framework, Thrive MSP 2040 and is expected to adopt this
plan in 2014. Currently, the 2030 Regional Development Framework does not recognize development
consistent with Scenarios 1, 2 and 3 in the AUAR. The City of Rosemount and Empire Township will
need to partner with the Council to identify potential community and regional infrastructure
improvements and timeframes necessary to accommodate the UMore development scenarios as identified.
Among the development Scenarios detailed in the AUAR, when particular land uses are finalized, the
Council expects both the City and the Township to amend their respective comprehensive plans.

Dear Mr. Zweber,
Thank you for providing the Minnesota Department of Health (MDH) with the opportunity to
comment on Draft Alternative Urban Areawide Review (AUAR) for the UMore Study Area
project.
Asbestos /Hazardous Waste
The AUAR notes that site investigations have identified debris and abandoned structures that
may contain asbestos. Prior to the demolition of structures or removal of debris that is identified
as potentially containing asbestos, an inspection must be conducted according to 40 CFR 61 —
National Emissions Standards for Hazardous Air Pollutants (NESHAP). Any required asbestos
inspection activities must be completed in compliance with the Minnesota Asbestos Abatement
Act and Rules, described in Minnesota Statutes Sections 326.70 to 326.81 and Minnesota Rules,
Parts 4620.3000 to 4620.3724. For additional information or for assistance interpreting the
results of asbestos surveys, contact MDH staff at (651) 201 -4620 or health.asbestos -
leadkstate.mn.us. Additionally, a pre - demolition survey of structures must be conducted
according to Minnesota Rules 7035.0805 to properly identify all hazardous waste. Specific
Questions concerning pre- demolition surveys need to be directed to the Minnesota Pollution
Control Agency at (651) 296 -6300.
Affordable Housing
Preserving affordable housing supports home - ownership and housing stability, improves
community stability, and fosters social networks. This is important for health in a number of
ways. When residents spend less than 30 percent of pre -tax income on housing (affordability
threshold) they have more money to spend on healthcare, doctor visits, medication, and healthy
food. Additionally, instable housing — or frequent mobility — can cause stress and other mental
health conditions like depression. The supply of stable, affordable housing is shrinking and
demand is increasing. The project does provide a mix of housing densities but should also
consider providing affordable housing options.
Drinking Water Protection
In two recent letters to the City, MDH discussed issues that remain unaddressed in the current
AUAR. The first letter (April 2, 2013) provided two guidance documents that relate to wellhead

highly vulnerable portion of the Drinking Water Supply Management Area (DWSMA). These
water quality concerns were not addressed in the AUAR and therefore, the points raised by these
two letters continue to be current and valid. They have been resubmitted as attachments to this
comment letter.
Energy Consumption
Reduced energy consumption results in decreased fossil fuel burning in power plants, and thus
lowers carbon emissions from these plants. The project should consider ways, such as those
described in the Concept Master Plan, to conserve energy, reduce energy use, eliminate or reduce
greenhouse gas emissions, and promote the use of renewable energy.
Health Impact Assessment
A Health Impact Assessment (HIA) is a research and community engagement process that can be
used to help ensure that people's health and concerns are being considered when decisions on
infrastructure and land use projects are being made. The National Research Council defines HIA
as "a structured process that uses scientific data, professional expertise, and stakeholder input to
identify and evaluate public - health consequences of proposals and suggests actions that could be
taken to minimize adverse health impacts and optimize beneficial ones." HIAs have been used to
provide important health information to decision makers on a wide range of projects outside the
typical health arena, including comprehensive plans, brownfield redevelopment, transportation
projects, energy policies, and housing projects. Over 100 HIAs have been performed in the US to
help improve public health. Ten HIAs have been completed in Minnesota, mostly on
comprehensive plans and transportation projects. An HIA could provide recommendations to
policy makers to support possible positive health outcomes and to mitigate or prevent possible
negative health outcomes to improve the public's health and to inform zoning, permitting,
monitoring, and other policies.
Physical Activity
Encouraging physical activity by providing parks, recreational facilities, and trails can be an
effective strategy to improve the public's health. Additionally, trips taken by bike or foot versus
automobile save energy and do not emit pollutants or greenhouses gases. The project should
consider bicycle and pedestrian connections and accessibility, such as those described in the
Concept Master Plan, so that future users of the site would have safe and convenient access to
these facilities.
Storm Water Runoff/ Impervious Surfaces
The substantial increase in impervious surfaces at project build out will increase the amount of
stormwater runoff from the site. Stormwater runoff picks up and carries with it many different
pollutants that are found on paved surfaces such as sediment, nitrogen, phosphorus, bacteria, oil,
grease, trash, pesticides and metals. Reducing stormwater runoff helps prevent contaminated
runoff from entering streams, lakes and other water bodies, which may be used for recreational
purposes or drinking water. Waterborne illnesses from recreational swimming and drinking
water are associated with runoff. An increase in impervious surfaces also has been shown to lead
to higher flood peaks.
Future climate conditions are anticipated to result in increased frequency and intensity of storm
events. The project should consider whether stormwater infrastructure and retention facilities
Mr. Zweber
UMore Study Area AUAR

designed for larger storm events would be appropriate to accommodate anticipated future
climatic events.
Well Construction
New wells that are constructed in Minnesota must be constructed according to the requirements
of Minnesota Statutes. Chapter 1031, and Minnesota Rules, Chapter 4725. Any wells constructed
for dewatering or water quality monitoring will be subject to these requirements. Abandoned
wells will need to be properly sealed. Additional information is available on the MDH website at
Well Construction and Well Sealing. For additional information, contact MDH staff at
(651) 201 -4600 or health.wellsgstate.mn.us.
Health starts where we live, learn, work, and play. To create and maintain healthy Minnesota
communities, we have to think in terms of health in all policies. Thank you again for the
opportunity to provide comments on this AUAR for the UMore Study Area. Feel free to contact

Dear Mr. Brotzler:
I am writing this letter to provide the city of Rosemount (the City) with updated guidance documents
regarding 1) "Wellhead Protection Issues and Strategies Related to Mining Activities" and
2) "Evaluating Proposed Stormwater Infiltration Projects in Vulnerable Wellhead Protection Areas."
These documents have evolved since the Minnesota Department of Health (MDH) last discussed them
with the City and we understand you are currently working on an ordinance pertaining to large -scale
aggregate mining. MDH has no authority over local zoning or land use decisions and offers these
guidance documents to you for reference in your decision process.
It is the MDH perspective that the City should consider both the protection of its source water and the
protection of the Prairie du Chien - Jordan regional aquifer. It is our understanding that some of the
proposed mining activity and a resultant mine pit -lake will be located within a highly vulnerable
portion of the City's drinking water supply management area ( DWSMA), as approved in the amended
Part 1 report (March 18, 2011). A rating of high vulnerability indicates that waterborne contaminants
could take only weeks to years to reach the aquifer, therefore great care should be taken in this portion
of the DWSMA to prevent the release of contaminants during mining activities. The proposed mining
activities will remove all of the unconsolidated material above the Prairie du Chien, which is a highly
fractured bedrock that is hydraulically connected to the Jordan Aquifer in which the City's wells are
completed. The resultant mine pit -lake could be a direct conduit for contamination into the aquifer and
is located directly upgradient of City wells Rural Well 1 South (457167) and Rural Well 2 North
(474335).
We recognize the city's commitments to providing safe and clean drinking water to its residents.
Please contact me with any questions regarding these MDH guidance documents (651/201- 4658).

Dear Mr. Brotzler:
Subject: UMore Mining Permit Document Review
It is our understanding that the City of Rosemount (the City) is currently reviewing the permit
application for the planned'UMore aggregate mine. We have reviewed some of the submitted
documents and believe that there are deficiencies in the water quality monitoring strategy as
proposed in the "Hydrogeologic Study and Water Monitoring Plan." In particular, it does not
include provisions for evaluating changes in the water chemistry of the City wells that may
result from the direct recharge from surface water into the aquifer.-
The mining activities as proposed will result in a mine -pit lake that will be hydraulically
connected to the bedrock aquifer upgradient of the City wells. A portion of this lake will be
located within a highly vulnerable portion of the City's current Drinking Water Supply
Management Area (DWSMA). This lake will focus groundwater recharge into the•bedrock
aquifer that is used by the City and will have the potential to affect the water quality in the
aquifer, particularly if the city constructs more water supply wells in this area. The City
should be -aware that the Minnesota Department of Health (MDI -1) may have to designate
affected city wells as groundwater sources that are under the direct influence of surface water
should changes in water quality reflect rapid surface water recharge to the aquifer. If this
were to happen, the City lriay face additional expense in order to meet Federal surface water,
treatment regulations.
The City is currently working on Part 2 of their wellhead protection plan. The proposed
mining activities will need to be addressed in the section relating to the impact of land and
water use. changes. This is also an opportunity to incorporate measures into your plan that
will aid in determining the risks to your water supply that this mining activity may pose.
Adding specific measures to your plan that relate to characterizing or managing this potential
source of contaminationwill,qualify the City to be eligible for MDH Implementation Grant
funding to.help defray the cost of monitoring.

Subject: Re: UMORE Draft AUAR - DNR Comments
Mr. Zweber,
The Department of Natural Resources (DNR) has reviewed the Draft Alternative Urban Areawide Review
(AUAR) for the UMORE Study Area located in the City of Rosemount, Dakota County. We offer the
following comments for your consideration.
The DNR has had the opportunity to participate in discussions and pre - publication reviews for this
document. Early coordination opportunities are appreciated as they help to identify issues /concerns
early in the process and allow for considerations early in planning. The DNR encourages the City to
continue communications with the DNR through the development stages of this project.
In addition to scheduled AUAR updates, the DNR recommends that the Natural Heritage Information
System (NHIS) Database be re- evaluated during major construction events. Regarding NHIS reviews, the
DNR considers report queries valid for one year. New records are constantly being updated into the
system. In the event that a new rare feature(s) or state - listed species are located on or in the vicinity of
the project area, avoidance or mitigation measures may need to be considered.
As identified in the Draft AUAR, the Vermillion Highlands Research Recreation and Wildlife
Management Area is located south adjacent to the study area. The DNR appreciates the consideration of
this resource in planning scenarios and encourages the City to continue discussions with the DNR as
more definitive site plans are developed.
The DNR encourages that project developers consider use wildlife - friendly erosion control mesh where
erosion control mesh is needed. Traditional erosion control mesh has been found to be detrimental as
wildlife can become entangled leading to injury or death. A flyer is attached for your reference.
Please note that additional information may be requested or required when DNR water appropriation
permit applications are submitted for the construction of a new well. A 2013 statutory change requires
that all new well construction receive pre - approval from the DNR prior to construction of the well. The
statutory changes is to help well owners to make informed decision by providing relevant information
prior to their financial investment in equipment and well construction. Please contact the DNR Area
Hydrologist for more information on the applicability of this statutory change to your project.
The DNR is supportive of and appreciates all wildlife and rare features considerations and commitments
as presented in the Draft AUAR.
Thank you,

Dear Mr. Zweber:
Thank you for the opportunity to review and comment on the Draft Alternative Urban Areawide Review
(Draft AUAR) for the UMore Study Area project (Project) located in the city of Rosemount, Minnesota.
The Project consists of a 4,900 acre mixed use development. Regarding matters for which the Minnesota
Pollution Control Agency (MPCA) has regulatory responsibility and other interests, the MPCA staff has
the following comments for your consideration.
Water Quality — Surface Water Runoff (Item 17)
• The Draft AUAR states that stormwater management for the new development will utilize regional
ponds constructed to "NURP Standards" as a pre- treatment method prior to discharge into area
water bodies. It is important to note that the MPCA does not recognize these standards as
comparable to meeting the requirements for wet sedimentation basins as described in the National
Pollutant Discharge Elimination System /State Disposal System (NPDES /SDS) General Construction
Stormwater Permit that will be required for the site. Construction of permanent wet sedimentation
basins and regional ponds to treat stormwater runoff from new impervious surfaces will, at a
minimum, need to meet all the requirements outlined in Part III. C. 1. of the permit and incorporate
any revisions to this part as a result of upcoming changes to the 2013 permit.
• The MPCA encourages the use of infiltration of stormwater, where possible, as a method of
permanent stormwater management. The design of the infiltration systems must also meet all
requirements identified in Part III. C. 2. of the NPDES /SDS Construction Stormwater Permit.
• The MPCA encourages the city and county to consider incorporating Minimal Impact Design
Standard (MIDS) practices into its plan to retain stormwater on the site and minimize discharges to
area surface waters. More information can be found at http : / /www.pca.state.mn.us /veiza8e.
The Draft AUAR identifies the presence of numerous land- locked depressions and wetlands on the
site that may be utilized as part of the stormwater management system. However, it should be
noted that the NPDES /SDS prohibits adverse stormwater impacts (including permanent inundation,
flooding, degradation of water quality, filling, etc.) to natural wetlands (of any classification) unless
the impacts have been addressed through permits or other approvals as described in Appendix A,
Part D of the Permit.
Mr. Eric Zweber
Page 2
July 10, 2013
• The Draft AUAR states the site does not discharge to impaired waters, but does not identify whether
the site will discharge to any special waters within one mile of the site. If the site will discharge to
special waters, permanent treatment volumes will double for the site. For questions regarding
stormwater issues, please contact Roberta Getman at 507 - 206 -2629.
We appreciate the opportunity to review this project. Please be aware that this letter does not
constitute approval by the MPCA of any or all elements of the Project for the purpose of pending or
future permit action(s) by the MPCA. Ultimately, it is the responsibility of the Project proposer to secure

Subject: AUAR for the UMore Study Area - MPCA Remediation Program comments
Importance: High
Eric, MPCA Remediation Program staff has reviewed the draft AUAR for the UMore Development
Area. While Remediation Program staff do not have any specific comments, the MPCA does want to
reiterate and emphasize some key points related to the project.
• As was noted in the draft AUAR, releases of hazardous substances have been identified in
various areas throughout UMore Park. These releases have occurred from various activities
during operation of the Gopher Ordnance Works (GOW), after GOW operations ceased, and
since the property has been owned by the University of Minnesota.
• Under Minnesota State Superfund Law (the Minnesota Environmental Response and Liability
Act, Minn. Stat. ch. 115B), both the U.S. Department of Defense and University of Minnesota are
considered to be responsible parties for these releases. The MPCA recognizes there maybe
other parties that may also responsible for releases, such as operators and /or lessees, at the
site.
• As more specific development plans are finalized, updated environmental assessments will need
to be completed and response actions plans and /or contingency plans prepared which address
implementation of appropriate actions relative to site remediation activities. The work, and
subsequent documents, should undergo appropriate review /approval by the MPCA's Superfund
or Brownfield programs.
• The MPCA has recommended that both the University of Minnesota and Army Corps of
Engineers enter into a formal agreement with the MPCA for oversight of such assessments and
response action development. The MPCA has also encouraged the U of M and Corps begin
discussions as to the allocation of workload with respect to further assessments and response
actions, including discussions related to actions to address physical hazards from GOW
operations that remain at the site.
As noted above, these are comments on the draft AUAR are from the MPCA Remediation
Program. MPCA Environmental Review Program staff may have comments that may also be forwarded
to you. The MPCA looks forward to working with the city on these issues as this important project
moves forward.

Thank you for the opportunity to review the UMORE AUAR. Please note that MnDOT's review -
of this AUAR does not constitute approval of a regional traffic analysis and is not a specific
approval for access or new roadway improvements. As plans are refined, we would like the
opportunity to meet with our partners and to review the updated information. MnDOT has

Please correct if this was an error.
For questions concerning these issues, please contact David. Sheen (651- 234 -7824) in MnDOT
Metro District's Traffic Section.
Modeling.
The most prominent issue concerning the modeling for UMORE is that the methodology used for
forecasting traffic is not effective for analyzing regional system impacts and needs. While the
Dakota County Travel Demand Model was used to forecast 2030 "background" traffic increases,
it was not used for the forecast project impacts. The Regional Travel Demand. Model or Dakota
County Travel Demand Model should have been used to forecast the impacts of the increased
25,000- 35,000 population and the 18,000 - 24,500 employment for the 7.7 square miles area.
The ITE Trip Generation Manual is appropriate for estimating trips at the local level for small
geographic areas, where the model does not provide enough detail. For a development of this size
and scale, any analysis of the regional system should be done using the regional or County model
in order to better assess internal trip relationships. Without confidence in the regional traffic
impacts, it's perhaps premature to adequately assess the detailed and more localized impact as
well as the mitigation recommendations.
While some trip reduction was applied to account for pass -by trips and internal trips, it's unclear
how these factors were estimated. Page 9 of the traffic study notes that the trips assumed
generated by the UMore development is "conservative." It is unclear how conservative is
defined.
The ITE Trip Generation Manual provides information concerning the trips arriving and
departing by peak hours and by land use type, but not to and from distribution on the larger
system. It should be clarified how the trip distribution was estimated (Travel demand model or
elsewhere).
One of the merits of the proposed development seems to be to minimize non - motorized trips,
which may reduce some traffic impacts. It would be helpful to see an estimate of non - motorized
trips generated.
For questions concerning these comments, please contact Jim Henricksen, MnDOT Metro
District's Traffic Forecaster at 651 - 234 -7782.
Design:
Any significant changes to the State Highway System will require a MnDOT Layout. MnDOT
recommends that the design work be completed by a consultant that is experienced working with
MnDOT standards and has performed Trunk Highway design.
The following web sites provide layout design guidance and identify layout requirements:

For questions concerning the layout process and timing, please contact Nancy Jacobson, MnDOT
Metro Design Section at 651- 234 -7647
Noise Mitigation:
MuDOT's policy is to assist local governments in promoting compatibility between land use and
highways. Residential uses located adjacent to highways often result in complaints about traffic
noise. Traffic noise from this highway could exceed noise standards established by the
Minnesota Pollution Control Agency (MPCA), the U.S. Department of Housing and Urban
Development, and the U.S. Department of Transportation. Minnesota Rule 703 0.003 0 states that
municipalities are responsible for taking all reasonable measures to prevent land use activities
listed in the MPCA's Noise Area Classification (NAC) where the establishment of the land use
would result in violations of established noise standards.
MnDOT policy regarding development adjacent to existing highways prohibits the expenditure of
highway fiinds for noise mitigation measures in such areas. The project proposer should assess
the noise situation and take the action deemed necessary to minimize the impact of any highway
noise. If you have any questions regarding MnDOT's noise policy please contact Peter Wasko in
our Design section at (651) 234 -7681.
Permits:
Any use of or work within or affecting MnDOT right of way requires a permit. Permit forms are
available from MnDOT s utility website at htW://www.dot.state.mn.us/utili

forecasting traffic is not effective for analyzing regional system impacts and needs. While the
Dakota County Travel Demand Model was used to forecast 2030 "background" traffic increases,
it was not used for the forecast project impacts. The Regional Travel Demand Model or Dakota
County Travel Demand Model should have been used to forecast the impacts of the increased
25,000- 35,000 population and the 18,000- 24,500 employment for the 7.7 square miles area.
The ITE Trip Generation Manual is appropriate for estimating trips at the local level for small
geographic areas, where the model does not provide enough detail. For a development of this size
and scale, any analysis of the regional system should be done using the regional or County model
in order to better assess internal trip relationships. Without confidence in the regional traffic
impacts, it's perhaps premature to adequately assess the detailed and more localized impact as
well as the mitigation recommendations.
While some trip reduction was applied to account for pass -by trips and internal trips, it's unclear
how these factors were estimated. Page 9 of the traffic study notes that the trips assumed
generated by the UMore development is "conservative." It is unclear how conservative is
defined.
The ITE Trip Generation Manual provides information concerning the trips arriving and
departing by peak hours and by land use type, but not to and from distribution on the larger
system. It should be clarified how the trip distribution was estimated (Travel demand model or
elsewhere).
One of the merits of the proposed development seems to be to minimize non - motorized trips,
which may reduce some traffic impacts. It would be helpful to see an estimate of non- motorized
trips generated.

District's Traffic Forecaster at 651- 234 -7782.
Noise Mitigation:
MnDOT's policy is to assist local governments in promoting compatibility between land use and
highways. Residential uses located adjacent to highways often result in complaints about traffic
noise. Traffic noise from this highway could exceed noise standards established by the
Minnesota Pollution Control Agency (MPCA), the U.S. Department of Housing and Urban
Development, and the U.S. Department of Transportation. Minnesota Rule 7030.0030 states that
municipalities are responsible for taking all reasonable measures to prevent land use activities
listed in the MPCA's Noise Area Classification (NAC) where the establishment of the land use
would result in violations of established noise standards.
MnDOT policy regarding development adjacent to existing highways prohibits the expenditure of
highway funds for noise mitigation measures in such areas. The project proposer should assess
the noise situation and take the action deemed necessary to minimize the impact of any highway
noise. If you have any questions regarding MnDOT's noise policy please contact Peter Wasko in
our Design section at (651) 234 -7681.
Permits:
Any use of or work within or affecting MnDOT right of way requires a permit. Permit forms are
available from MnDOT's utility website at lhttp: /hvww.dot.state.mn,us /utility/
Please include one 11 x 17 plan set and one full size plan set with each permit application.
Please direct any questions regarding permit requirements to Buck Craig (651- 234 -7911) of
MnDOT's Metro Permits Section.
Review Srrbniit1W Options:
Mn/DOT's goal is to complete the review of plans within 30 days. Submittals sent in
electronically can usually be honed around faster. There are four submittal options. Please
submit either:
1. One (1) electronic pdf version of the plans. Mn /DOT can accept the plans via e-mail
at metrodevreviews,dot c state.mn.us provided that each separate e-mail is under 20
megabytes.
2. Three (3) sets of frill size plans. Although submitting seven sets of full size plans
will expedite the review process. Plans can be sent to:

p. 17: 8.) Permits and Approvals, Table 8 -1. Dakota County requires permits, licenses and /or
approvals for compliance with its ordinances (e.g., solid waste, hazardous waste, subsurface
sewage treatment, wells and water supplies).
p. 18: 9.A.) Existing Land Uses. Although past and present land uses in UMore Park are briefly
discussed elsewhere in the Draft AUAR, the University of Minnesota must make a full and
complete disclosure of all past and present land uses whether by the University itself, its former
and current tenants or by others (e.g., federal government and military and State of Minnesota
agencies). Property transactions implicit with this proposed development, as well as those that
have already occurred (e.g., Vermillion Highlands, City of Rosemount and Dakota County
Technical College), require veracity, due diligence to protect potential buyers from incurring
environmental liabilities that are known or should be known (e.g., contaminant releases and
asbestos).
p. 20 -31: 9.E.) Superfund Site Status, and 9.F.) Potential Environmental Hazards. This
respondent has been associated with many aspects of the investigations, remedial efforts and
variable outcomes surrounding the former Gopher Ordnance Works (FGOW), Rosemount
Research Center and Agricultural Experiment Station citizen complaints and discoveries of
solid and hazardous waste disposals and contaminant releases were made in 1984. The Draft
AUAR excludes a much larger body of work conducted from 1984 through 2000, which should
be included to provide the necessary context for a public review of this import. Through its Site
Assessment and Remediation Program, Dakota County has documented more than a hundred
FGOW and UMore Park disposal and release sites that have not been satisfactorily resolved.
Despite evidence to the contrary, the State and federal Superfund site activities excluded the
FGOW choosing instead to focus on a few of the many disposals and contaminant releases at
UMore Park (e.g., the University's hazardous waste burn pits, Georges Used Equipment, Porter
Electric and US Transformer). In 2002, a preliminary investigation of the FGOW was conducted
jointly by the University, MPCA and Dakota County, and its significant findings (2003) were
presented to the US Army Corps of Engineers ( USACE), which manages the congressionally
funded DERP for formerly used defense sites (FUDS) like the FGOW. The USACE conducted a
preliminary assessment and concluded that the University was a "responsible party" with others,
which has since led to administrative and legal wrangling but no remedial actions, exposure
mitigation or cleanups.
The MPCA is charged with enforcing MERLA, whether it proceeds cooperatively with USACE
under DERP to address the FGOW and /or requires the University of Minnesota, as a
responsible party, to follow through with Superfund actions. What appeared to be significant
causes for both DERP and Superfund actions several years ago have become sidetracked by
the University's push for developing a residential and business community and aggregate
mining at UMore Park. Economic and commercial interests have overtaken the environmental

concerns, and the leaders of State and local governments, who are charged with protecting
public health and safety, must decide who they represent.
Suffice it to say that this section of the Draft AUAR needs significant revision if it is to properly
and fully inform the public and its decision makers on this important and long reaching
development plan. Seventy -one years of land use and unfortunate abuse must be addressed
here before a secure and healthy future can be realized.
p. 39 -50: 13.A.) Water Use. Existing Conditions. More than 80 farms were seized and
purchased in 1942 for the construction of the FGOW, and only a few were retained and used.
All unused, abandoned wells should be found and properly sealed in accordance with State
Rules and Dakota County Ordinance 114. Because the majority of these wells are shallow, they
may connect with a contaminated aquifer. Ordinance 114 requires that such wells be tested for
contaminants and remediated if necessary before they are sealed.
The Jordan sandstone, the primary aquifer utilized by the City of Rosemount for its public water
supply, is susceptible to contamination because of its interconnection with the overlying
fractured and solution- weathered dolostones of the Prairie du Chien Group (Shakopee and
Oneota formations). In the vicinity of UMore Park, the Jordan sandstone aquifer is notably
contaminated with elevated nitrate - nitrogen, and the two eastern wells of Rosemount's water
supply are impacted.
While the origins of oxidized nitrogen to the Jordan aquifer have been attributed largely to
agriculture and somewhat less significantly to sewage (i.e., failed and malfunctioning residential
and commercial sewage treatment systems), a third source has not been considered. The
FGOW's disposals and releases of ammonia, nitroamines and nitrotoluenes are known to have
entered the unsaturated (vadose) zone above the water table and over time degraded and
oxidized eventually recharging the shallow and deeper aquifers. Groundwater monitoring for
residual nitroamines and nitrotoluenes, especially 2,4 -DNT and 2,6 -DNT that were used in
smokeless gunpowder production, beneath and east of UMore Park should be conducted to
determine if their residuals are still extant.
Although a specific bedrock geology map of the Coates Quadrangle (topographic map) has not
been published, the adjacent quadrangles (Vermillion, Hastings and St. Paul Park) are
available. Interpreting the bedrock geology from available well logs confirm the probable
structural displacements (block faulting, folds, etc.) that continue southwestward into the Coates
Quadrangle and define the southern limits of the Twin Cities Basin. Those structures likely
underlie the east and south portions of UMore Park. As a result of this and the presence of
covered and possibly buried karsts on -site, as well as to the east and north of UMore Park, the
City of Rosemount's DWSMA should be revised utilizing the Minnesota Department of Health
Source Water Protection guidance for wellhead protection delineation for fractured and solution -
weathered bedrock hydraulically connected to a bedrock aquifer (i.e., Prairie du Chien - Jordan
aquifer).

Comments on City of Rosemount Draft AUAR More Study Area
The future dependency on the Jordan aquifer to serve the burgeoning population of Rosemount
and the proposed UMore Park development is predicated on locating future public wells away
from the more vulnerable groundwater aquifer under and near UMore Park. Therefore, any
scenario that would include a public well sited within UMore Park should be dismissed unless
testing and treatment for contaminants of concern are provided.
p. 58: 17.D.) Water Quality — Surface Water Runoff. Water Quantity and Quality Mitigation Plan.
Any proposed plan or scenario that would divert storm water and other surface water discharges
(e.g., NPDES- permitted discharges) to the aggregate mining lake (Lake 2162) should be
dismissed. Because Lake 2162 will be located in a critical aquifer recharge area, any
contaminants entering the lake will eventually impact the Jordan aquifer. Therefore, it is also
critical that contingency plans be in place and enforced should spills, willful disposals and
accidental releases occur that would jeopardize the water quality of the lake.
p. 70: 19.B.) Geologic Hazards and Soil Conditions. The Rich Valley Karst, a soil - mantled,
covered karst, is located within a mile north and northeast of UMore Park. It is a karst dry valley
in which no surface water flows as it is immediately intercepted by soil subsidence dolines
(sinkholes). Anecdotal evidence of fractured and solution- weathered conduits in the underlying
Prairie du Chien Group's dolostones and sandstone (Shakopee and Oneota formations) was
provided to this respondent by area well drillers, as well as comments on drillers' logs.
Portions of UMore Park and adjacent lands to the east suggest that some of the closed
depressions attributed to a pitted glacial outwash plain (Rosemount outwash) may have
enlarged and deepened in response to the piping (hydraulic tunneling) of fine sediments into
underlying fractured and solution- weathered dolostone (Prairie du Chien Group) and similar
piped voids in the residual superjacent St. Peter sandstone. Because of an extensive early
Ordovician Period (Paleozoic) erosion interval after the deposition of the Prairie du Chien
Group, as well as recurrent structural displacements, some of the Shakopee formation is
missing in the area of eastern Rosemount, UMore Park and the City of Coates. It is likely that
this was a paleokarst, in which the partially solution- weathered and missing Shakopee formation
was subsequently buried by the deposition of the St. Peter sandstone. Subsequent depositional,
weathering and glacial /interglacial events evolved into the current landscape where the
karstification process is continuing subaerially. The very deep closed depressions in UMore
Park and farther east suggest that the rapid infiltration of surface water is being enhanced by
the rejuvenation of both the covered and buried karsts.
p. 107: 27.) Compatibility with Plans and Land Use Regulations. Based upon the comments
above, Scenario 4 (status quo) would be the safest option for Rosemount and Empire Township
until the University of Minnesota has complied with federal, State and County regulations
regarding known and suspected solid and hazardous waste disposals, contaminant releases,
and environmentally impacted air, land and water and mitigated their human and ecological
exposures.

Subject: UMORE park development plan
Hello. I hope I am squeaking in under the wire of the comment deadline, since I heard it was July 10 and
it's still July 10 as I write.
Regarding the development plan for UMORE park, my comment is to not do it. Instead, get Prairie
Restorations in there to restore the native prairie and plants. Have trails, picnic tables, a visitors
center. That land should stay as it is, with minimal intervention.
There are so many reasons why this land should not be built on. I will mention only a few here.
1. 1 noticed in your development plan that you've designated land way down in Empire Township to stay
as it is with no buildings. But why should people have to drive that far to be able to walk in a quiet, green
space? We're already so crowded with concrete, houses, stores, and roads. We don't need more of
those; there are a million stores everywhere and a million houses, and millions of acres of
concrete. What we do not have much of - -and it's disappearing all the time - -is land that is left to itself,
land where one can go and listen to the quiet; land where one can see and feel and hear beauty. There's
no way to put a price tag on such a place, and there are fewer and fewer of these as time goes by. What
is one more ugly, stupid Target or WalMart or whatever - clothing- store -you- can - think -of, compared to the
beauty of a prairie vista with bird song and the wind blowing in the grass?
Richard Louv, author of Last Child in the Woods, mentions research that finds that direct exposure to
nature is essential for healthy childhood development and for the physical and emotional health of
children and adults. Having natural spaces easily accessible and surrounding us is not a luxury. We
need it. We are part of the earth and need contact with it. People should have access to natural spaces
close by and not have to drive to get there.
The idea to maintain 4000 acres of natural space in Vermillion is good, but not enough because it
removes natural space from the city of Rosemount. I mean natural space: not manicured parks. One
does not get the same benefit from a park full of mowed Kentucky bluegrass that one gets from a wide
expanse of forest, prairie, or oak savannah.
2. The city calls it "open space," but let us not forget that we are not the only living things on this
planet. Animals and plants are already living in that space where you plan to build. Where is your
concern for them? Where are they supposed to go when you bulldoze their homes, kill the trees and
plants and probably kill some of the animals, too? We squeeze animals into smaller and smaller spaces,
and then complain when they have nowhere to go, nothing to eat (because we bulldozed their food and
turned it into mowed lawns) and come in our yards. We may not realize it, but we depend on those
animals and plants for our survival. They are all part of a web that keeps us alive. Stress the web too
much, take too much away, and we will be in big trouble. We should be trying to preserve every possible
inch of natural land, rather than planning what stores or houses we want to put on it. It's incredibly selfish
to take homes away from animals, and kill living things (trees, plants, and anything else that gets in our
way) just so we don't have to drive outside the city limit to get to a clothing store.
3. All those plants in that green space help to make oxygen. Take 5000 acres of that away, and it adds
proportionally to global warming.
4. Eagan has managed to maintain a swath of green space, much of it natural, for several miles, running
down the middle of the city. Why can't you do that? Do you really want to become another Apple Valley,
with nothing but ugliness from one end to the other? Stores, roads, houses, acres of concrete and
thousands of cars a day going through there? It's urban sprawl, and it's UGLY. Don't add to it. Keep
Rosemount from turning into yet another community that succumbed to the siren call of urban
sprawl: Keep Rosemount beautiful.
5. Take the long view. Do you think that whatever stores you build in that space will still be there in 100
years? They won't. But the land, if you leave it natural, will be there for much longer -- especially if it's
formally protected by the state or the Nature Conservancy. Once the land is built on, it's dead; the
ecosystem is compromised or destroyed and it will never support life again. It's incredibly short- sighted to
put in a store just because someone doesn't want to drive outside the city limits, if you also lose the
ecosystem that's there and the inestimable value of that natural space. If you build there, it will be a
tragedy and a cause for mourning, not a cause for celebration.
The happiest days of my life have been spent in natural spaces. There aren't many left. Don't add to the
destruction. Leave spaces for people to breathe, and be, and get away from the madding crowd. And
leave space for the animals, too, because we aren't the only living things on this planet.
I think my view will be unpopular with city planners, who are conditioned to think, "What can we put here,"
when given the opportunity to build. And the lure of all those extra taxes is hard to resist. But there are
others who think as I do. Think of them, and think of the long -term future hundreds of years from
now. Think of our descendants, and ask whether they will have any natural spaces left. Think of the
animals and birds, and whether they will all be gone because of having nowhere to live. Think of the
suffering it will cause them if you bulldoze that land and put it all under concrete. On the day you build on
that land- -and for a long time afterward- -the earth will cry, and so will I.
Sincerely,
Martha Henderson
