Why is Mn/DOT proposing another bridge?
-
Existing
Trunk Highway (TH) 41 is one of the most heavily-traveled two-lane roads in
Minnesota, carrying over 18,000 vehicles per day; 20% of these vehicles are
trucks. The resulting traffic congestion, noise and vibration pose serious
quality of life concerns for downtown Chaska.
-
Traffic
congestion is projected to worsen on TH 41, as well as on Highway (Hwy) 101, as
the southwest metropolitan area continues to develop. By our forecast study
year (2040), TH 41 and Highway 101 are expected to be congested 10 hours a day. By this time, the
Bloomington Ferry Bridge will also be congested.
-
Both
TH 41 and Hwy 101 bridges are low bridges, located within the 100-year
floodplain. As a result these bridges or associated approach roadways are under
water, often for many days, when the Minnesota River floods. The most recent
significant flood (2001) closed the TH 41 bridge for 25 days and the Highway
101 bridge for 29 days. These closures cause major traffic disruptions and
emergency service response delays for the entire southwestern metropolitan area.
-
There
is poor north-south principal arterial connectivity between TH 169 and New TH
212. The only non-circuitous route between these two major roadways is on
existing TH 41.
-
The
Minnesota Department of Transportation (Mn/DOT) is responsible for the
development and maintenance of a safe and efficient state highway system that
meets the transportation needs of the public. It is our job to alleviate
traffic congestion on state roads and ensure adequate access and mobility in
support of a strong regional economy.
-
The
need for a crossing that would bridge the Minnesota River above the floodplain
and connect TH 169 to New TH 212 has been recognized for over 30 years. A
specific route to meet this need was studied in the 1970s but was not further
pursued at that time due to fiscal constraints and more immediate transportation
problems. Now, Scott and Carver Counties are rapidly growing. The Metropolitan
Council has identified a new river crossing in this area as a regional priority.
With the timeframe that is needed to implement a project of this magnitude,
Mn/DOT must be planning for this project now.
When would this new river crossing be built?
-
Funding for construction
is not currently included in either the Mn/DOT’s or Metropolitan Council’s
20-year fiscally-constrained transportation plans. Right of way preservation
funding is, however, included. While construction may be many years away, it is
important to decide where the future river crossing would be located so that
development and local transportation systems can be planned and right of way
can be preserved.
If construction is not within Mn/DOT’s 20-year plan, why is this study
being done now?
-
Right
of way preservation for a new regional crossing within this study area is
included in current Mn/DOT and Metropolitan Council plans. While actual
construction is not within current plans, in light of the rapid development
occurring in the study area, it is good planning to reserve the appropriate
corridor now so that it is available when the time comes to construct a new
crossing. Because of the planning timeframe, Mn/DOT is using the
"tiered" EIS process. The current Tier I EIS will address the
question of which corridor to reserve; a Tier II EIS addressing more detailed
design issues would be prepared much closer to the time of the construction of
a new river crossing.
What is an EIS and why is Mn/DOT preparing one?
-
“EIS” is the abbreviation
for Environmental Impact Statement. An EIS is prepared to meet federal and
state requirements to study project impacts on the social, economic and
environmental resources in the affected area. The alternatives and issues being
studied in the TH 41 river crossing EIS were identified during a two-year
“scoping” process. There are six
potential corridors being studied.
-
The EIS will address impacts
of the project alternatives on many resources, including (but not limited to) cultural
resources/historic properties; wetlands and other water resources; groundwater,
geology, and soils; parks, recreation areas, and the wildlife refuge; vegetation,
fish and wildlife, threatened and endangered species; noise, visual and air
quality; neighborhoods, community resources, and special populations; land use,
development, and economic conditions; and traffic operations and other modes of
transportation.
-
An EIS is prepared per
the regulations set out by the Council of Environmental Quality (CEQ) in
fulfillment of the National Environmental Policy Act of 1969 (NEPA). http://ceq.eh.doe.gov/nepa/regs/nepa/nepaeqia.htm
What does it mean to do a “Tier I” EIS?
-
The federal environmental
guidelines allow for a “tiered” two-step EIS process. Due to the extended timeframe
for this project, it makes sense to do detailed design much closer to actual
construction date; at that time a Tier II EIS will address more specific
impacts and mitigation. The Tier I EIS being prepared now will inform the
selection of a corridor, not a detailed design.
When will this EIS be published and where will I be able to read it?
-
The Draft EIS is expected to be published late
2006. Copies will be available for review at local libraries, city halls, county
government centers and Mn/DOT offices, as well as posted on this Web site. A
public hearing will be held following release of the Draft EIS and there will
be a 45-day formal comment period.
When will a corridor be selected?
Who makes the decision and how is the public involved?
-
Mn/DOT
and FHWA confer to identify the preferred alternative. We will do so following thorough review of
the environmental studies and in consultation with other federal “cooperating
agencies” (the U.S. Army Corps of Engineers, Environmental Protection Agency
and Fish and Wildlife Service), as well as the many other stakeholder groups
involved in the study.
-
The selection of a
preferred alternative will occur following the formal comment period on the
Draft EIS. During this comment period, the Draft EIS will be available for
review and a public hearing will be held. Public and agency comments received
on the Draft EIS will be considered as part of the preferred alternative decision.
-
Following selection of a
preferred alternative, a Tier I Final EIS will be prepared. The public will be invited
to review the Final EIS document and comment on its adequacy. The environmental
review process is concluded when the FHWA issues a federal “Record of Decision”
(which will include responses to substantive comments made on the Final EIS) and
Mn/DOT issues a state “Adequacy Determination”.
Who else is involved in this project?
What happens after the preferred alternative is selected and the
environmental process is complete?
-
Following the conclusion
of the environmental process, Mn/DOT can begin working with cities and counties
to preserve right of way. This process will include official mapping of the corridor,
dedication of right of way as part of new development, and purchase.
How many alternatives are being considered? Will some of these alternatives
be eliminated from further consideration soon?
-
Six alignments are being
studied in the Draft EIS. This is reduced from a total of 21 Build alternatives
assessed during the scoping process. It is not anticipated that any of the six alternatives
will be eliminated prior to the publication of the Draft EIS. The purpose of
the Draft EIS is to document the impacts of each of the alternatives on the
natural, built and social environment in order to fully inform the decision as
to which corridor to preserve for future construction.
Why even consider an alignment where there are existing neighborhoods when
there is undeveloped land further west?
Why even consider an alignment near a calcareous fen?
Why even consider an alignment through a state recreation area?
Why even consider an alignment through a national wildlife refuge?
-
The numerous social and environmental
constraints in the study area create a significant challenge for siting a new
river crossing. The study area includes established business areas and neighborhoods
(including mobile home parks), planned development areas, two historic
downtowns and numerous other historic resources, the Minnesota Valley National
Wildlife Refuge, a state recreation area, the Seminary Fen/Assumption Creek
wetland complex as well as the extensive wetlands throughout the valley and, of
course, the Minnesota River itself.
-
Mn/DOT, along with its
stakeholders, evaluated 21 Build alternatives during the project’s scoping
process before narrowing the options to six to be studied in detail. The first
“cut” eliminated further consideration of alternatives that did not meet the identified
transportation need. The final cut during scoping eliminated those options that
had greater impacts but no more benefit than those that were retained for
further study in the Draft EIS.
-
Mn/DOT understands that
each of the remaining alternatives has serious impact potential. The western
area has relatively little development but is home to a national wildlife refuge
and also cuts through the edge of a developing community, the City of Carver. The
central area includes the refuge, a state recreation area, developing land, and
proximity to historic downtown Chaska. The eastern area has an existing roadway
corridor as well as land that, based on earlier studies, has been preserved for
the project for nearly 30 years; however, this area also has many existing
homes and businesses and a sensitive calcareous fen wetland complex. These are
only a few of the many potential “pros and cons” involved in the study options.
In addition, different alternatives have different travel-related benefits and serve
different trip needs. The final corridor decision will need to consider these
many factors; the Draft EIS will provide analysis to assist in that
consideration.
What is more important – impacts on wildlife habitat or on people’s homes?
-
The environmental process
under National Environmental Policy Act (NEPA) http://ceq.eh.doe.gov/nepa/regs/nepa/nepaeqia.htm requires that social, economic and environmental considerations be included in
the planning of projects that receive federal funding. Similarly, the Minnesota
Environmental Policy Act (MEPA) requires discussion of environmental, economic,
employment, and sociological impacts.
-
The purpose of NEPA as
stated in 42 USC Section 4321 is “to declare a national
policy which will encourage productive and enjoyable harmony between man and
his environment; to promote efforts which will prevent or eliminate damage to
the environment and biosphere and stimulate the health and welfare of man; to
enrich the understanding of the ecological systems and natural resources
important to the Nation; and to establish a Council on Environmental Quality.”
-
The
Council of Environmental Quality (CEQ) has set regulations for environmental
review in order to carry out the NEPA purpose, as well as guidance to further
express the intent of these regulations. In the CEQ memorandum: “Forty Most Asked Questions Concerning CEQ’s
NEPA Regulations” http://ceq.eh.doe.gov/nepa/regs/40/40p3.htm it states that the CEQ “recognizes that
the identification of the environmentally preferable alternative may involve
difficult judgments, particularly when one environmental value must be balanced
against another. The public and other agencies reviewing a Draft EIS can assist
the lead agency to develop and determine environmentally preferable alternatives
by providing their views in comments on the Draft EIS.”
-
Mn/DOT
likewise recognizes that there may be difficult judgments in the selection of a
corridor for this important river crossing. The Draft EIS will assess impacts to the
entire range of socioeconomic and natural resources including (but not limited
to) existing and future development, national wildlife refuge and other
wildlife habitat, Seminary Fen and other wetlands, and cultural resources, and
will document how each alternative performs in solving the problems that led to
the project being proposed in the first place.
-
The final decision will
represent an assessment of each alternative’s benefits (i.e. traffic congestion
relief, regional highway connectivity, and “flood-proof” travel) and costs
(i.e. impacts on the social, physical and natural environment, as well as
monetary cost). In addition, the decision will consider the ability to
adequately mitigate the impacts that are posed by each alternative.
Why not raise the elevation of the Hwy 101 bridge?
Why not build a river crossing in Jordan instead since development will
have occurred to the west of the study area by the time of construction?
Why not invest in transit instead of building more roads?
-
The travel forecasts
developed for this project include assumptions about transit use based on Metropolitan
Council transit plans. In addition, during the scoping process, we studied an
alternative that assumed more aggressive work-related trip reduction (through
transit use and measures such as flextime and telecommuting) than is actually anticipated
in regional plans. It was found that even with these more aggressive transit use
assumptions, existing TH 41 would not have sufficient capacity to handle forecast
traffic.
Will my home be acquired? If so, when
would this occur and what is the process?
-
Each of the alternatives
being studied would require Mn/DOT to acquire right of way from currently
developed land; some alternatives would affect more existing homes or
businesses than others. For purposes of the Tier I EIS, a general corridor
width is being assumed in order to quantify property impacts of the various
alternatives. The Tier I Draft EIS will include figures showing these assumed
“construction limits” and which properties they would affect. In addition,
preliminary construction limits will be included in displays to be shown at the
next public open house in Spring 2006.
-
The outcome of the Tier I
EIS process will be a selected corridor for right of way preservation. Upon
completion of the EIS process Mn/DOT will work with local communities and the
affected landowners to identify the best approach to preserve the needed right
of way. It will most likely involve official mapping of the selected corridor. “Official
Mapping” is a local zoning tool that enables Mn/DOT to work with the local
communities to acquire undeveloped properties within the selected corridor
where development is imminent as well as open market sales or hardship
acquisitions of existing homes or businesses (i.e. the river crossing alignment
makes selling the property difficult). Early acquisition efforts are limited by
law to willing sellers. When the bridge construction is programmed then it will
be necessary to complete acquisitions of all the properties and eminent domain
actions may be required if negotiated settlements cannot be reached.
Many
homeowners expressed concern at the open house about whether it is permitted or
a good idea to make home improvements (replace siding, decks, etc.). At this
point in the study process, homeowners may continue with property improvement
plans. If your property is within the selected corridor and an acquisition is
necessary, improvements that have been made will be considered in the appraisal
process.
In
terms of new development, Mn/DOT is encouraging cities to take the river
crossing alignments into consideration during the local approval process. To
date, Mn/DOT is not aware of any local development moratoriums on the river
crossing alignments.
-
All right of way
acquisition and relocation must be done in accordance with procedures set by
federal and state law. Mn/DOT relocation advisors help develop individual
relocation plans.
How noisy will it be near the road? Will there be noise walls?
-
The
Draft EIS will include a specific analysis of existing, future “No Build” and
future “Build” daytime and nighttime noise levels at numerous noise-sensitive
“receptors” (such as homes and recreational lands) for each of the alternatives.
The Draft EIS will also compare these levels to federal and state noise
standards.
-
The
decision on noise walls or other noise mitigation would be made after the Tier
II EIS, during final design, and in accordance with federal and state policy in
place at the time. Currently, noise walls are installed when they meet established
cost-effectiveness criteria (i.e. they achieve a set level of noise reduction
within a defined cost). The location and design of noise walls and materials
are reviewed with affected communities during the design process.
How high and how long will the bridge be?
-
Depending on the alternative,
the bridge will between approximately 60 and 75 feet above the river and will span
the entire 100-year flood plain, similar to the Bloomington Ferry Bridge. Due
to the local topography and the width of river valley, the bridge will be long
(1¾ to 2¾ miles, depending upon the alternative). Detailed design of the bridge
and roadway will take place during the Tier II EIS process, much closer to the
time of construction.
How will local access to existing TH 169 or New TH 212 change if this
project is built?
-
New TH 212 is currently
under construction in Carver and Hennepin Counties. All of the local
interchanges that are part of the New TH 212 project will be accommodated under
any of the TH 41 river crossing alternatives being studied, though some minor
modifications to the New TH 212 interchanges may be needed.
-
There are long-term plans
to convert existing at-grade intersections on TH 169 into interchanges at existing
TH 41 and Highway 69 in Scott County. These plans are also accommodated within
the design of each of the river crossing alternatives being studied.
Why didn’t Mn/DOT build this project 30 years ago when it was first studied?
-
A Draft EIS was prepared
for a single TH 41 corridor alignment alternative in the eastern portion of the
study area in the early 1970s. (The E-2 alignment being assessed in the current
EIS is similar to the alignment evaluated in the 1970s’ study.) However, further environmental study and
implementation decisions about this corridor were deferred due to funding
constraints and more pressing transportation needs at the time.
