Re: Finding of No Significant Impact Minnesota State Project Number 1981-124 I-35W Over the Minnesota River Project In the Cities of Bloomington and Burnsville Hennepin and Dakota Counties, Minnesota
Dear Mr. Zelle:
Enclosed is a Finding of No Significant Impact (FONSI) as requested by the Minnesota Department of Transportation (MnDOT). The proposed project consists of replacing the existing I-35W bridge over the Minnesota River east of the existing alignment, the I-35W bridges over West 106th Street, vehicle mobility issues, raising I-35W profile to address flood events, and bicycle/pedestrian connectivity. This Finding concludes that the project will not significantly impact the human environment.
A Notice of Availability of the FONSI must be sent to Federal, State, and local government agencies that are likely to have an interest in the undertaking and to the State intergovernmental review contacts. It is encouraged that agencies, which commented on the Environmental Assessment (or requested to be informed) are advised on the project decision, the disposition of their comments and provided a copy of the FONSI.
If you have any questions, please contact me at (651) 291-6110 or [email protected] .
Sincerely, PHILIP J FORST 2018.04.11 09:47:16 -05'00'

FEDERAL HIGHWAY ADMINISTRATION FINDING OF NO SIGNIFICANT IMPACT AND SECTION 4(F) DETERMINATION
I-35W Over the Minnesota River Dakota and Hennepin Counties
Cities of Burnsville and Bloomington, Minnesota April 11, 2018
BACKGROUND The Federal Highway Administration (FHWA) and the Minnesota Department of Transportation (MnDOT) prepared a combined Environmental Assessment (EA) and Environmental Assessment Worksheet (EAW) for the I-35W Over the Minnesota River Project in compliance with the National Environmental Policy Act (NEPA) (42 U.S.C. § 4231 et seq.) and Minnesota Environmental Policy Act processes (M.S. 116D).
MnDOT is the project sponsor and responsible governmental unit (RGU) for the I-35W Over the Minnesota River.
The project includes reconstructing I-35W between Cliff Road in Burnsville to West 106th in Bloomington. The existing I-35W bridge over the Minnesota River will be replaced essentially on existing alignment. Major features of the Preferred Alternative include:
x A steel girder bridge over the Minnesota River x Extending the existing I -35W northbound truck climbing lane from south of West 10th to
Cliff Road x Reconstructing of the I-35W bridges at the I-35W/West 106th Street interchange x Raising the vertical profile of I-35W (south of the Minnesota River Bridge) to reduce the
risk of roadway flooding
The project is being led by MnDOT Metro District.
STATEMENT OF PURPOSE AND NEED
Purpose The purpose of the I-35W Over the Minnesota River Project is address bridge condition at multiple locations, improve I-35W traffic operations and accommodate pedestrian and bicycle movements across the Minnesota River.
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 1
-
Need The identified needs for this project are summarized below. Project needs include:
To address the deteriorating condition of the bridge structures across the Minnesota River and at the I-35W/West 106th Street interchange
Maintain traffic to maximum extent possible during construction Address traffic operations on northbound I-35W Address bicycle and pedestrian movements across the Minnesota River Address roadway flooding
See Chapter 3 of the Environmental Assessment/Environmental Assessment Worksheet (EA/EAW) for the detailed discussion of project need.
ALTERNATIVES Chapter 4 of the EA/EAW describes the alternatives considered in greater detail. Figure I of this document provides an overview of the process. In addition to the No Build Alternative, Rehabilitation Alternative, and Build Alignment Alternatives, as shown in Table 1 and Bridge Type Alternatives as shown in Table 2, were considered for the project elements.
Due to bridge roadway, and non-motorized components, a four-step process (Figure I) was followed for evaluating the alternatives. Screening criteria were applied for the various elements of the project to better identify differences, benefits and impacts. If an alternative did not meet the defined purpose and need, it was eliminated from further study.
Each of the remaining alternatives was evaluated in the EA/EAW. The evaluation considered engineering and environmental factors. Engineering factors included constructability, service life, maintenance, and cost. Environmental factors considered included the impacts that would occur to biological resources, historic and cultural resources, as well as socioeconomic impacts, changes in noise and vibration levels, and impacts to wetlands and water quality.

ALTERNATIVES ELIMINATED Through the alternatives analysis process described in the EA/EAW, it was determined that some of the alternatives either did not fully address purpose and need, did not address purpose and need as well as other alternatives, and/or had greater social, economic, and environmental impacts. Therefore, they were eliminated.
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 3
-
Rehabilitation Alternative
This alternative was eliminated for the following reasons:
Construction cost similar to cost of a new bridge
No meaningful extension of existing bridge service life
Future expansion (widening) is precluded
On Existing Crossing Alignment
This alternative was dismissed for the following reasons:
I-35W alignment would be shifted closer to homes Black Dog interchange ramps anticipated to be pushed into wetlands and storm water treatment basin
On Shifted Alignment (shifted to west of existing bridge) This alternative was dismissed for the following reasons:
I-35W alignment would be shifted closer to homes Black Dog interchange ramps anticipated to be pushed into wetlands and storm water treatment basin
No-Build Alternative Under the No-Build Alternative, the bridge condition would not be addressed and there would be no modifications to address bridge condition. The No-Build Alternative was eliminated because it does not meet the project purpose and need.

Bridge type alternatives E through H were dismissed for reasons including cost, greater SEE impacts (e.g. flyway issues) as well as potential river navigation clearance issues. Alternatives A through C, inclusive, have lower overall SEE impacts, no known river navigation clearance issues, lower construction cost, and no above deck elements.
PREFERRED ALTERNATIVE The preferred alternative (shifted alignment to east of existing bridge) evaluated in the EA/EAW from the alternatives that are listed in Table 1 and the Bridge Type Alternative in Table 2. The On Shifted Alignment (shifted to east of existing bridge) is the alternative that best meets the purpose and need of the project. The preferred alternative assumed a steel plate girder type for purposes of impact assessment but the four bridges types in Table 2 will be available to potential design-build contractor in the bidding process.
The No-Build Alternative was evaluated as further described in the EA/EAW as a basis against which to compare the Build Alternatives in evaluation of environmental impacts, but was not identified as the selected alternative because it did not meet the project purpose and need.
Benefits of Selected Alternative The selected alternative provides three main benefits. First, it addresses the primary and secondary project needs. Second, it has an overall lower cost of construction. Third, it minimizes wetland impacts compared to the other alternatives.
Based upon the EA/EAW, included by reference with its appendices in this FONSI in its entirety, FHWA and MnDOT have concluded that the preferred alternative, including the mitigation measures for unavoidable impacts, will have no foreseeable significant impact on the quality of the natural and human environments. The preferred alternative is best able to achieve the proposed action purpose and need without significant environmental impacts.
ENVIRONMENTAL CONSEQUENCES AND MITIGATION The EA describes the existing conditions in the project area and the potential impacts and mitigation that would result if the selected alternative is implemented. Information was gathered from various sources, including site observations, maps, aerial photography, and local state and federal agency data.
The following environmental factors were analyzed and recorded for the portion of the selected alternative in the United States:
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 5
-
Land Use Water Resources (including Section 404) Contamination, Hazardous Materials, and Regulated Waste Fish, Wildlife, Plant Communities and Sensitive Ecological Resources Historic Resources Construction Noise and Dust Social Impacts Right of Way Noise and Vibration Section 4(f) Section 7 – Endangered Species
The following environmental factors were analyzed, and no impacts were recorded for the selected alternative:
Aesthetic/Visual Air Quality Airport Zones Environmental Justice Farmland/Agriculture Groundwater Section 106 Section 6(f) Wild and Scenic Rivers
Land Use
Floodplain: The 100-year floodplain of Minnesota River is within the project area. These floodplains are fairly well contained within the banks of the river within the project area. Approximately 56,600 cubic yards of fill will be placed in the Minnesota River floodplain.
A floodplain assessment has been completed. The bridge piers are not anticipated to create changes in the floodplain either upstream or downstream. Hydraulic models indicate a 0.01-foot decrease in the future flood stage based upon the proposed bridge.
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 6
-
Agency Finding: Based on the mitigation measures discussed in this section, FHWA finds the proposed project will not result in any significant impacts to land use including floodplains.
Water Resources Surface Waters: The build alternative will involve work in surface waters of the Minnesota River.
Stormwater Management: The project must comply with the National Pollutant Discharge Elimination System/State Disposal System Construction Stormwater (NPDES) Permit requirements. For the roadway portions of the project, rate control and infiltration volume will be provided for the net new impervious surface as required by the NPDES permit. The project will result in an increase in impervious of 0.9 acres. The roadway project proposes to construct seven best management practices (BMPs).
Wetlands and wet ditches: There will approximately 0.3 acres permanent wetland impacts and 0.16 acre of wet ditch impacts are attributed this project. Temporary wetland impacts are anticipated but are not quantified at this time.
Agency Finding: Due to the limited impact the proposed project will have on water resources, FHWA finds the proposed project will not result in significant impacts on water resources and will require mitigation within the regulatory thresholds for surface water including surface water, groundwater, stormwater, water appropriation, wetlands and wet ditches.
For waters under the jurisdiction of the USACE, the USACE and the MPCA have a joint application form. Permits from the USACE, including General Permits and Letters of Permission that may require mitigation commitments for MnDOT.
Contamination/Regulated Waste There is a low likelihood of encountering contaminated materials as a result of construction activities. Six known contaminated groundwater or soil were identified near the project area. Any potentially contaminated materials encountered during construction will be handled and treated in accordance with applicable state and federal regulations. It is not anticipated that construction work would release contaminated dust particles to the surrounding populace; however, minimization measures will avoid, control, and manage these efforts.
Agency Finding: FHWA finds the proposed project will result in the low likelihood of encountering contaminated materials. Since the wastes generated by construction of the proposed project will be disposed of
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 7
-
properly following completion of the proposed project and the construction impacts will be subject to mitigation, there will not be significant impacts associated with contamination and regular waste.
Fish, Wildlife, Plant Communities and Sensitive Ecological Resources The project area is in a riverine watercourse that contains many resident fish species. Any wildlife displaced would likely relocate to suitable nearby areas, including waters immediately adjacent to the project area. The areas limited to the waterway and banks in the construction limits.
MnDOT will undertake protection measures to include: design and stage the project to avoid or minimize impacts to fish and fish habitat.
Agency Finding: Due to the limited impact the proposed project will have on ecological resources, FHWA finds the project will not result in significant impacts on ecological systems and MnDOT will undertake recommended protection measures.
Historic Resources The project was reviewed by the MnDOT Cultural Resources Unit for potential effects to historic properties.
Agency Finding: FHWA finds the project will not impact any historic properties.
Construction Noise and Dust Construction related activities will result in temporary noise level increases associated with construction equipment and pile driving. Elevated noise levels are, to a degree, unavoidable for this type of project. MnDOT will require that construction equipment be properly muffled and in proper working order. MnDOT will require its contractors to comply with applicable local noise restrictions and ordinances to the extent that is reasonable.
Dust generated during construction will be minimized by MnDOT through standard dust control measures such as applying water to exposed soils and limiting the extent and duration of exposed soil conditions. Construction contractors will be required to control dust and other airborne particulates in accordance with MnDOT specifications in place at the time of project construction. During construction, particulate emissions will temporarily increase due to the generation of fugitive dust associated with activities such as grading and other soil disturbance. The following dust control measures will be considered:
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 8
-
Minimize the duration and extent of areas being exposed or regraded at any one time. Spray construction areas and haul roads with water, especially during periods of high
wind or high levels of construction activity. Minimize the use of vehicles on unpaved surfaces when feasible. Pave, apply water as needed, or apply (non-toxic) soil stabilizers on unpaved access
roads, parking areas and staging areas at construction sites. Use water sweepers to sweep paved access roads, parking areas and staging areas at
construction sites. Use water sweepers to sweep streets if visible soil material is carried onto adjacent public
streets. Hydroseed or apply (non-toxic) soil stabilizers to inactive construction areas Enclose, cover, water or apply (non-toxic) soil binders to exposed stockpiles (dirt, sand,
etc.). Utilize appropriate erosion control measures to reduce silt runoff to public roadways. Replant vegetation as quickly as possible to minimize erosion in disturbed areas. Use alternative fuels for construction equipment when feasible. Minimize equipment idling time. Maintain properly tuned equipment.
Agency Finding: FHWA finds that because the construction impacts will cease following completion of the proposed project and the construction impacts will be subject to mitigation, the proposed project will not result in significant impacts associated with construction.
Social Impacts Consideration of effects to the social and economic environment include: an assessment of the community characteristics and cohesion, protected groups of people, environmental justice, public facilities and services, changes in travel patterns, relocations of residences or businesses, economic impacts, land use, growth and economic development and changes to pedestrian or bicycle facilities.
No impacts were identified with regard to community characteristics and cohesion, protected groups of people, environmental justice, and public facilities and services.
Permanent negative changes in pedestrian and bicycle facilities are not anticipated as a result of the project. Temporary occupancy (23 CFR § 774.13(d)) during construction is expected and is discussed in the Section 4(f) Determination section within this document.
No businesses or residences will be relocated.
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 9
-
Agency Finding: FHWA finds the proposed project will provide a positive long-term social impact for residents and businesses.
Right of Way The project will not displace any residents or businesses. The City of Bloomington will deed two parcels to MnDOT for transportation purposes. The transportation purposes are the construction, operations, and maintenance of stormwater ponds and a bicycle/pedestrian trail.
Agency Finding: No relocations will be required. The Uniform Relocation and Real Property Acquisition Act of 1970, as amended by the Surface Transportation Uniform Relocation Assistance Act of 1987 and 49 CFR, Part 24, and effective April 1989 will be followed for the project by MnDOT, to compensate landowners for easements acquired for this project.
Noise and Vibration Traffic noise levels were modeled at representative receptor locations throughout the project area. In general, the analysis determined that construction of the project will result in increases in highway traffic noise levels compared to existing conditions. Changes in daytime traffic noise levels exceed applicable state or federal noise thresholds at over 70 receptor locations.
Agency Finding: FHWA finds the proposed project will result in noise impacts requiring consideration of noise abatement measures but not significant noise or vibration effects.
Section 4(f) Determination Section 4(f) of the U.S. Department of Transportation Act (DOT Act) of 1966 (49 U.S.C. 303) states that FHWA cannot approve the use of land from publicly owned parks, recreational areas, wildlife, and waterfowl refuges or public and private historic sites unless the following conditions apply: (1) there is no feasible and prudent alternative to the use of the property; and (2) the action includes all possible planning to minimize harm to the property resulting from use. Temporary occupancy of a Section 4(f) resource may not be considered a use if certain conditions are met: duration is temporary; no change in ownership of property; minor scope of work; no anticipated permanent adverse physical impacts; no interference with the activities or purpose of the resource; property will be fully restored to pre-project condition or better; and there is documented agreement from the Official With Jurisdiction (OWJ) over the resource (23 C.F.R. 774.13(d)).
Evaluation of the project has determined that although there are two Section 4(f) resources that would be impacted by all project build alternatives, the project does have unavoidable impacts to two Section 4(f) resources: The City of Bloomington Trail and the Minnesota State Water Trail.
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 10
-
These two Section 4(f) resources will be closed intermittently or continuously during construction. The activities, attributes, and features of these resources are not anticipated to experience permanent adverse physical impacts.
Agency Finding: For the reasons stated above, FHWA finds the proposed project will result in a temporary occupancy of the City of Bloomington Trail and the Minnesota State Water Trail.
Section 7 – Federal Threatened and Endangered Species As stated in the EA/EAW, MnDOT’s Office of Environmental Stewardship (OES), is FHWA’s designated representative to review Section 7 resources within Minnesota for federally-listed threatened species. There are four species with a range that includes the project location:
x Northern Long-Ear Bat (NLEB), (Myotis septentrionalis) x Higgens Eye pearlymussel x Rusty-patch bumble bee x Prairie bush clover x Snuffbox mussel
Agency Finding: FHWA finds the proposed project “may affect, likely to adversely affect” the northern long-eared bat. The MnDOT Wildlife Ecologist noted that the project will occur within the northern long-eared bat’s range, but there are no documented maternity roosts and/or hibernacula within the project area. No tree removals will occur within 0.25-mile of a known hibernaculum or within 150 feet from a maternity roost tree.
FHWA finds the proposed project will have “No Effect” on the Higgens Eye pearlymussel, rusty-patched bumble bee, prairie bush clover, or snuffbox mussel.
USFWS did not object the conclusion reached by MnDOT OES Wildlife Ecologist acting on behalf of FHWA.
COMMENTS AND COORDINATION During preparation of the EA/EAW, early coordination and consultation was initiated with agencies, stakeholder groups, and the public to incorporate their comments and concerns into the development and analysis of the project purpose and need, alternatives, and potential environmental impacts. Public coordination included stakeholder meetings, briefings, and presentations are detailed in the EA/EAW.

Mitigation Mitigation describes any action taken to reduce the adverse effects of potential impacts. The order of precedence for dealing with impacts is listed below:
Avoiding the impact altogether by not taking a certain action or parts of an action Minimizing impacts by limiting the degree or magnitude of the action and its
implementation; rectifying the impact by repairing, rehabilitating, or restoring the affected environment
Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action
Compensating for adverse impacts by replacing or providing substitute resources or environments
The following sections describe the list of commitments to mitigation that are being committed to as part of this project. A more thorough listing of environmental commitments is an attachment to this FONSI.
Land Use
Floodplain: Mitigation includes 1:1 compensatory storage, as feasible. If 1:1 compensatory storage is determined not to be feasible during final design, then 1:1 compensatory storage will be implemented to the extent feasible and combined with a no-rise certificate supported by modeling information.
Water Resources Water appropriation: MnDOT will implement a dewatering plan, along with meeting all requirements included in the project SWPPP and NPDES Permit, during construction to ensure that the discharge does not adversely affect receiving waters and that the inlet and discharge points are adequately protected from erosion and scour.
Contamination/Regulated Waste MnDOT will require that any potentially contaminated materials encountered during construction will be handled and treated in accordance with applicable state and federal regulations. It is not anticipated that construction work would release contaminated dust particles to the surrounding populace; however, minimization measures will avoid, control, and manage these efforts.
MnDOT will dispose of all solid wastes generated by construction of the proposed project properly in a permitted, licensed solid waste facility.
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 13
-
If any contaminated spills or leaks occur during construction, MnDOT will require the contractor to notify the Duty Officer and work with the MPCA to contain and remediate contaminated soil/materials in accordance with state and federal standards.
Fish, Wildlife, Plant Communities and Sensitive Ecological Resources While impacts to sensitive species are not anticipated, MnDOT will implement the following protection measures:
Protect and preserve vegetation from damage in accordance with MnDOT Spec 2572.3. Construction operations that may impact the river bed will not occur during fish and
spawning migration periods (March 15th through June 15th) Use redundant sediment/erosion control BMPs for protection of areas of environmental
sensitivity.
Construction Noise and Dust To minimize construction noise disturbances, the following commitments have been made: MnDOT will require that construction equipment be properly muffled and in proper
working order. MnDOT will require its contractors to comply with applicable local noise restrictions and
ordinances to the extent that is reasonable.
MnDOT will ensure that construction contractors are required to control dust and other airborne particulates in accordance with MnDOT specifications in place at the time of project construction.
Right of Way The Uniform Relocation and Real Property Acquisition Act of 1970, as amended by the Surface Transportation Uniform Relocation Assistance Act of 1987 and 49 CFR, Part 24, and effective April 1989 will be followed by MnDOT for the project, to compensate landowners for property acquired for this project. For temporary impacts, MnDOT will ensure that land features will be returned to match their prior condition.
Section 4(f) Resources The City of Bloomington Trail and the Minnesota River State Water Trail will be returned to a state as good as or better than their pre-project condition.
Section 7 – Endangered Species MnDOT will ensure that the project includes minimization measures to prevent or reduce effects to the bat. Tree removal will not occur between June 1 and August 15th, inclusive, during calendar year 2018 in order to avoid possible impacts to the species. Any tree removal in post
I-35W Over the Minnesota River Project - Finding of No Significant Impact Page 14

_________________________________ ________________________
FHWA CONCLUSION
FHWA finds the elements of the I-35W Over the Minnesota River Project which require FHWA funding and the environmental impacts caused thereby have been adequately identified and assessed in the January 2017 EA/EAW as prepared by MnDOT and FHWA. Therefore, pursuant to 23 CFR 771.121(c), FHWA hereby finds the I-35W Over the Minnesota River Project will not cause significant environmental impacts.
FHWA has determined the proposed action will not result in the use of any Section 4(f) resources.
The FHWA has determined the proposed improvements, as described in the Environmental Assessment (EA) will have no significant impacts to the human or natural environment. This Finding of No Significant Impact (FONSI) is based upon the attached EA which has been independently evaluated by FHWA and determined to adequately discuss the need, environmental issues, and impacts of the proposed project and appropriate mitigation measures.
The EA provides sufficient evidence and analysis for determining that an Environmental Impact Statement is not required.
