North I-25 Environmental Impact Study
About the Project
The Federal Highway Administration (FHWA), in cooperation with the Colorado Department of Transportation (CDOT), have initiated an Environmental Impact Statement (EIS) to identify and evaluate multi-modal transportation improvements along approximately 70 miles of the I-25 corridor from the Fort Collins-Wellington area to Denver. The EIS will address regional and inter-regional movement of people, goods and services along the I-25 corridor.
Corridor History
As the primary route between Northern Colorado and the Denver metropolitan area, the I-25 corridor has experienced considerable growth over the years. People are increasingly aware that demands on the existing transportation system are exceeding its ability to serve travelers efficiently. Along with increased traffic volume on I-25 and parallel roadways has come an increase in accidents, resulting in a need to plan for transportation improvements within the corridor.
In 1993, CDOT initiated an “Environmental Assessment” (EA) for improvements to enhance the capacity and safety of I-25 between SH 7 and SH 66. The EA was followed by a "Finding of No Significant Impact" in 1995 that enabled CDOT to proceed with a series of construction projects that are ongoing. The current construction activities between SH 7 and Weld County Road 16 were addressed in the EA. Also addressed were the right-of-way acquisitions and utility relocations currently underway between Weld County Road 16 and SH 66. These are being done in anticipation of future construction.
In the late 1990s, CDOT, in conjunction with regional planning groups (North Transportation and Air Quality Planning Council, Upper Front Range Regional Planning Commission, and Denver Regional Council of Governments), undertook the North Front Range Transportation Alternatives Feasibility Study (TAFS) to evaluate an extensive range of alternative highway improvements, bus-transit alternatives, passenger-rail alternatives, and travel demand management programs from SH 7 to SH 14. This study, published in March 2000, produced a Vision Plan that included inter-regional bus service, combination general purpose/high-occupancy vehicle lanes, and passenger-rail service.
More recently, the Federal Highway Administration (FHWA), in cooperation with CDOT, prepared the Final EIS to identify and evaluate multi-modal transportation improvements along the I-25 corridor extending from Denver to Wellington. The Final EIS was released for public review in August 2011, and corridor-wide public hearings were held during September 2011 to collect public input during a 45-day comment period. In December 2011, FHWA signed the North I-25 Record of Decision (ROD), which completed the National Environmental Policy Act (NEPA) process for the North I-25 EIS. The completion of the NEPA process establishes planning guidelines for growth in segments of this corridor, addressing both land use and transportation issues.
Project Schedule
Through public comments and a collaborative effort involving leaders from local agencies and transportation agencies in Northern Colorado, a preferred alternative has been identified to be studied further in the Final EIS. During the FEIS, the preferred alternative will be analyzed in great detail including complete environmental impacts, funding opportunities and construction phasing. The project team will also respond to all public comments received during the Draft EIS review.
The Final EIS will then go through an internal review and comment process followed by FHWA and a public and agency review period similar to the DEIS. Comments received during the public review will be addressed in a Record of Decision (ROD) that describes the project or phase to be constructed, minor changes and clarification addressing comments. The ROD will identify funding for the approved action consistent with regional transportation plans included in the Metropolitan Planning Organization's planning documents. The final decision on the transportation improvements will be determined by the lead agency FHWA.
Preferred Alternative Identified
Over the past year, CDOT has been working closely with FHWA and local agencies to identify a preferred alternative. With guidance for public comments submitted during the Draft Environmental Impact Statement (DEIS) and an extensive collaborative effort, a preferred alternative has been identified which will include the following elements:
- General Purpose Lanes – one new general purpose lane in each direction of I-25 between SH 66 and SH 14.
- Tolled Express Lanes (TEL) – one buffer-separated TEL in each direction of I-25 from the existing HOV/Express Toll lanes at approximately 84th Avenue north to SH 14.
- Interchanges - 16 interchanges would be upgraded.
- Express Bus – Express bus with 13 stations along I-25, US 34 and Harmony Road with service from Fort Collins and Greeley to downtown Denver and between Fort Collins and DIA.
- Commuter Rail – Commuter rail service with nine stations connecting Fort Collins to Longmont and Thornton using the Burlington Northern Santa Fe Railroad right of way, generally paralleling SH 119 and tying into FasTracks North Metro rail in Thornton, which will connect to downtown Denver. Passengers may also connect to the FasTracks northwest rail in Longmont, which will travel to Boulder.
- Commuter Bus – Commuter bus service with eight stations along US 85 connecting Greeley to downtown Denver.
- Congestion Management- Some of the improvements include accommodations for ridesharing, carpools and vanpools, along with additional bicycle and pedestrian facilities. In addition, signal timing, ramp metering on I-25 and signage could also be improved.
Frequently Asked Questions
Q: Why is this study being done?
A: The Federal Highway Administration, Federal Transit Administration and the Colorado Department of Transportation have commissioned an Environmental Impact Statement (EIS) to determine the effect that adding various transportation improvements along I-25 will have on the lives of residents and commuters in the area.
Q: How does this study differ from previous studies?
A: This study will build on the findings of the previously completed North Front Range Transportation Alternatives Feasibility Study, which was a Major Investment Study completed in 2000. This EIS is the next step in planning for transportation improvements along the I-25 corridor.
Q: What is the difference between a Major Investment Study (MIS) and an Environmental Impact Statement (EIS)?
A: Major Investment Studies (MIS) and Environmental Impact Statements are both steps in the long-range process for finding alternatives to current and future challenges in a given area. The North Front Range Transportation Alternatives Feasibility Study (TAFS), an MIS, was completed in 2000 and examined regional solutions to safety problems, traffic congestion, air quality issues and mobility problems between the Northern Colorado population centers and metropolitan Denver. The North I-25 EIS, currently underway in the region, is a federal requirement set forth in the National Environmental Policy Act (NEPA). The EIS is a more in-depth study to determine the purpose and need of future transportation improvements in the same area; identify alternatives to be developed; and document the anticipated impacts of those alternatives. The North I-25 EIS is the next step in identifying alternatives for transportation issues.
Q: Why does this study encompass such a large area?
A: Recent transportation studies indicate communities in the north I-25 Front Range corridor can expect an estimated 43 percent increase in population and 36 percent increase in employment by the year 2020. A population gain exceeding employment gain means residents will have to travel to and from work on an already congested roadway. The EIS will explore regional transportation options mainly on I-25 in Northern Colorado, and perhaps also US 85 and US 287. The eastern boundary of the study area will be the US 85 corridor, and the western boundary will be the US 287 corridor.
Q: How long will the study take to complete?
A: We expect to complete the final Environmental Impact Statement in Fall 2010 with a record of decision in spring 2011.
Q: How will public input influence the statement?
A: Public input will help those conducting the study learn how residents and travelers in the area feel about existing and future transportation needs, alternatives that should be examined, and issues to address.
Q: How soon after the study is complete can we expect to see construction activity?
A: This process will determine whether transportation infrastructure improvements are necessary. If improvements are found to be necessary, the start of construction may be years away, dependant on many factors including the allocation of state and federal funding. However, this process must be completed before funds can be allocated and construction can begin.
Q: Are public meetings the only opportunity to comment?
A: Public input is not limited to public meetings. The team will accept input in all forms including letters, comments submitted to the Web site, and comment cards completed at public events and small meetings with civic, business and community groups. If you would like a presentation at a civic, business or community group, please contact Carol Parr at (970) 350-2170 or Long Nguyen at (970) 622-1280.

Environmental Impact Statement Process
For major transportation projects, the National Environmental Policy Act (NEPA) requires that a range of alternatives be considered and that their environmental impacts be analyzed. This type of study is required prior to the commitment of federal funds to any major project, or prior to any action taken by a federal agency that might cause a significant impact on the environment.
The North I-25 Environmental Impact Statement is led by the Federal Highway Administration. Basic steps in this process include:
- Scoping: A public process to help define the purpose and need for the proposed action or project and to identify environmental issues that need to be studied.
- Data Collection: Collecting transportation, environmental and land use data. This step will also include developing a tool for predicting future
(year 2035) travel. - Development of Alternatives: Identifying a wide range of highway, transit and other types of alternatives, then narrowing these to the reasonable range of alternatives for detailed study. This will include a
"No-Action" Alternative. - Analysis of Alternatives: Transportation, social, economic and environmental impacts of a reasonable range of alternatives are studied in detail and comparisons are made.
- Preparation of a Draft Environmental Impact Statement (DEIS): A printed report for public review and comment is prepared documenting the need for the project, describing alternative courses of action, analyzing likely impacts from each alternative, and describing any steps to be taken to avoid impacts or minimize harm to the environment.
- Public and Agency Review of the DEIS.
- Preparation of a Final Environmental Impact Statement: Documents preferred alternatives and provides response to comments that were made on the DEIS.
- Record of Decision: Documents the decision and commits to mitigation of impacts by the lead federal agency.
The Draft EIS Process
Since early 2006, the North I-25 EIS project team has been diligently working on the Draft Environmental Impact Statement (DEIS). The DEIS is an official document and includes the need for the project, describes alternatives considered, analyzes the environment, social and economic impacts for each alternative, and describe any steps to be taken to minimize, mitigate or avoid impacts. The complete DEIS process includes the following:
Step 1 - Development of DEIS Alternatives – Complete
The alternatives that remained after Level Three Screening were defined with a greater level of detail so that a full analysis can be completed. This greater level of detail includes:
|
|
Step 2 - Analysis of DEIS Packages – Complete
The two DEIS Packages and the No-Action Alternative will be fully analyzed, according to such areas as:
|
|
Step 3 - Documenting the DEIS Chapters – Complete
The information developed throughout the entire study will be documented in a federally required report. This will include:
|
|
Step 4 - Review Process – Complete
The Draft EIS document is reviewed in detail by the several divisions of CDOT, Federal Highway Administration (FHWA), Federal Transit Authority Administration (FTA) and several cooperating agencies (RTD, US Army Corps of Engineers, Federal Railroad Administration). Comments and recommendations from these agencies are then incorporated into the document. Local agencies will receive three months to review the document and provide comment on details in their area and the alternatives as a whole. The final version of the Draft EIS will be signed by CDOT, FHWA and FTA and made available for public review.
Step 5 – Public Comment Period –
(October 31-December 30, 2008) -- Complete
The DEIS public comment period lasts 60 days. Community members that are interested in reviewing and commenting on the DEIS can view hard copies of the document at specific city buildings and libraries or on the project Web site. During this time, the project team will host a series of public hearings to receive input on the DEIS and gather public comments. The comments provided by community members and other interested parties are considered and documented for incorporation into the Final EIS document.
Step 6: Evaluation to Develop Preferred Alternative
During the public comment period, the project team received 1,129 comments from interested citizens and agencies. We are now reviewing those comments and responding as appropriate. Although the formal public comment period for the Draft EIS is complete, the project team still welcomes questions and input from interested citizens. The project team continues to work with the project committees to define a preferred alternative, which we expect to announce this summer.

Transit Technologies/Highway Options
A multi-modal approach, including transit and highway options, is important in providing travel choices in the future and for helping meet transportation demand in northern Colorado. Throughout the North I-25 EIS study, the project team considered a wide range of transportation alternatives. To effectively meet transportation needs in northern Colorado, the following transit and highway solutions are part of the preferred alternative and will be analyzed in detailed in the Final EIS.
Bus Rapid Transit
- Distinctive, specialized vehicles with flexibility, frequency and speed of light rail
- Light rail-like stations provide fast and efficient boarding
- Local/regional bus service which operates in shared traffic or in an exclusive, fixed guideway
- Seats up to 70 people
- Average speeds up to 35 mph on arterials, 75 mph on freeways
Commuter Bus
- Standard 40' bus, articulated bus, or commuter coach
- Serves major highway corridors with fewer stops
- More regional service, longer distance trips
- Seats up to 60 people per bus
- Speeds up to 65 mph
Commuter Rail
- Heavier, diesel or electric locomotive pulling passenger cars
- Fewer stations than light rail, typically 5-10 miles apart
- Regional service, with average trips of 20+ miles
- Seats up to 150 people per car
- Average speeds of 60-80 mph
Toll Express Lanes
- Single-occupancy vehicles pay a toll and high occupancy vehicles travel in the lane free of charge.
- A combination of both barrier and buffer-separated lanes are used to separate the Tolled Express Lane (TEL) from the general purpose lanes.
- Slip ramp access provides at grade access and egress between the general purpose lanes and the TEL.
- New capacity: 3,400 people per hour per lane
- Average speed: 60 mph
- Capital Cost: $7.4 million per lane mile
General Purpose Lanes
- Most common method of adding travel capacity
- Standard paved lane that allows car and truck traffic
- New capacity: 2,400 people per hour per direction
- Average speed: 55 mph
- Capital Cost: $6.9 million per lane mile
North I-25 Commuter Rail Update
The North I-25 EIS was completed in 2011. During the development of the preferred alternative there was an expectation that an “Eastern Bypass” for freight rail could be created, promising to divert through-trains from the populated areas between Fort Collins and Denver to the eastern plains of Colorado, and allowing more track capacity to become available for passenger use. Changes in the economy, changes in the partnering relationships, and other studies over the last few years have come to varying conclusions.
Updating the assumptions for commuter rail in this corridor allows CDOT and local government partners to work from a common set of expectations for the commuter rail element of the North I-25 EIS. Further this effort is aligned with the State Rail Plan goal of maintaining Colorado’s readiness to pursue Federal funds should they become available. The commuter rail element of the EIS is shown as the brown line on the map, from Fort Collins through Longmont, and connecting to RTD’s North Metro line near 162nd Avenue & Colorado Boulevard.
The study is updating three main areas: (1) right-of-way, (2) operating plan, and (3) cost estimates. The EIS assumed that the existing single track configuration could be augmented with limited passing sidings and right-of-way implications. With freight service remaining on the corridor, combined with the operating plan discussed below and the knowledge learned from the RTD/BNSF negotiations on the Northwest Corridor (same BNSF line), the track configuration will require full double tracking with additional passing sidings, and expanded right-of-way needs. Correspondingly, the operating plan and commuter rail travel times will be updated.
The goal of the cost-estimating task is to update the right-of-way needs and to establish an appropriate cost for the US 287 / BNSF Railway corridor, inclusive of updating from 2009$ values of the FEIS to current 2014$. At the end of the process, the final updated cost estimate will be presented in “standard cost category” (SCC) format used by both the Federal Transit Administration (FTA) and Federal Railroad Administration (FRA).

Project Fact Sheet
The project fact sheet, with project information and Frequently Asked Questions, can be accessed by contacting the project team.
The Federal Highway Administration (FHWA), in cooperation with the Colorado Department of Transportation (CDOT), have initiated an Environmental Impact Statement (EIS) to identify and evaluate multi-modal transportation improvements along approximately 70 miles of the I-25 corridor from the Fort Collins-Wellington area to Denver. The EIS will address regional and inter-regional movement of people, goods and services along the I-25 corridor.
Corridor History
As the primary route between Northern Colorado and the Denver metropolitan area, the I-25 corridor has experienced considerable growth over the years. People are increasingly aware that demands on the existing transportation system are exceeding its ability to serve travelers efficiently. Along with increased traffic volume on I-25 and parallel roadways has come an increase in accidents, resulting in a need to plan for transportation improvements within the corridor.
In 1993, CDOT initiated an “Environmental Assessment” (EA) for improvements to enhance the capacity and safety of I-25 between SH 7 and SH 66. The EA was followed by a "Finding of No Significant Impact" in 1995 that enabled CDOT to proceed with a series of construction projects that are ongoing. The current construction activities between SH 7 and Weld County Road 16 were addressed in the EA. Also addressed were the right-of-way acquisitions and utility relocations currently underway between Weld County Road 16 and SH 66. These are being done in anticipation of future construction.
In the late 1990s, CDOT, in conjunction with regional planning groups (North Transportation and Air Quality Planning Council, Upper Front Range Regional Planning Commission, and Denver Regional Council of Governments), undertook the North Front Range Transportation Alternatives Feasibility Study (TAFS) to evaluate an extensive range of alternative highway improvements, bus-transit alternatives, passenger-rail alternatives, and travel demand management programs from SH 7 to SH 14. This study, published in March 2000, produced a Vision Plan that included inter-regional bus service, combination general purpose/high-occupancy vehicle lanes, and passenger-rail service.
More recently, the Federal Highway Administration (FHWA), in cooperation with CDOT, prepared the Final EIS to identify and evaluate multi-modal transportation improvements along the I-25 corridor extending from Denver to Wellington. The Final EIS was released for public review in August 2011, and corridor-wide public hearings were held during September 2011 to collect public input during a 45-day comment period. In December 2011, FHWA signed the North I-25 Record of Decision (ROD), which completed the National Environmental Policy Act (NEPA) process for the North I-25 EIS. The completion of the NEPA process establishes planning guidelines for growth in segments of this corridor, addressing both land use and transportation issues.
Project Schedule
Through public comments and a collaborative effort involving leaders from local agencies and transportation agencies in Northern Colorado, a preferred alternative has been identified to be studied further in the Final EIS. During the FEIS, the preferred alternative will be analyzed in great detail including complete environmental impacts, funding opportunities and construction phasing. The project team will also respond to all public comments received during the Draft EIS review.
The Final EIS will then go through an internal review and comment process followed by FHWA and a public and agency review period similar to the DEIS. Comments received during the public review will be addressed in a Record of Decision (ROD) that describes the project or phase to be constructed, minor changes and clarification addressing comments. The ROD will identify funding for the approved action consistent with regional transportation plans included in the Metropolitan Planning Organization's planning documents. The final decision on the transportation improvements will be determined by the lead agency FHWA.
Preferred Alternative Identified
Over the past year, CDOT has been working closely with FHWA and local agencies to identify a preferred alternative. With guidance for public comments submitted during the Draft Environmental Impact Statement (DEIS) and an extensive collaborative effort, a preferred alternative has been identified which will include the following elements:
- General Purpose Lanes – one new general purpose lane in each direction of I-25 between SH 66 and SH 14.
- Tolled Express Lanes (TEL) – one buffer-separated TEL in each direction of I-25 from the existing HOV/Express Toll lanes at approximately 84th Avenue north to SH 14.
- Interchanges - 16 interchanges would be upgraded.
- Express Bus – Express bus with 13 stations along I-25, US 34 and Harmony Road with service from Fort Collins and Greeley to downtown Denver and between Fort Collins and DIA.
- Commuter Rail – Commuter rail service with nine stations connecting Fort Collins to Longmont and Thornton using the Burlington Northern Santa Fe Railroad right of way, generally paralleling SH 119 and tying into FasTracks North Metro rail in Thornton, which will connect to downtown Denver. Passengers may also connect to the FasTracks northwest rail in Longmont, which will travel to Boulder.
- Commuter Bus – Commuter bus service with eight stations along US 85 connecting Greeley to downtown Denver.
- Congestion Management- Some of the improvements include accommodations for ridesharing, carpools and vanpools, along with additional bicycle and pedestrian facilities. In addition, signal timing, ramp metering on I-25 and signage could also be improved.
Frequently Asked Questions
Q: Why is this study being done?
A: The Federal Highway Administration, Federal Transit Administration and the Colorado Department of Transportation have commissioned an Environmental Impact Statement (EIS) to determine the effect that adding various transportation improvements along I-25 will have on the lives of residents and commuters in the area.
Q: How does this study differ from previous studies?
A: This study will build on the findings of the previously completed North Front Range Transportation Alternatives Feasibility Study, which was a Major Investment Study completed in 2000. This EIS is the next step in planning for transportation improvements along the I-25 corridor.
Q: What is the difference between a Major Investment Study (MIS) and an Environmental Impact Statement (EIS)?
A: Major Investment Studies (MIS) and Environmental Impact Statements are both steps in the long-range process for finding alternatives to current and future challenges in a given area. The North Front Range Transportation Alternatives Feasibility Study (TAFS), an MIS, was completed in 2000 and examined regional solutions to safety problems, traffic congestion, air quality issues and mobility problems between the Northern Colorado population centers and metropolitan Denver. The North I-25 EIS, currently underway in the region, is a federal requirement set forth in the National Environmental Policy Act (NEPA). The EIS is a more in-depth study to determine the purpose and need of future transportation improvements in the same area; identify alternatives to be developed; and document the anticipated impacts of those alternatives. The North I-25 EIS is the next step in identifying alternatives for transportation issues.
Q: Why does this study encompass such a large area?
A: Recent transportation studies indicate communities in the north I-25 Front Range corridor can expect an estimated 43 percent increase in population and 36 percent increase in employment by the year 2020. A population gain exceeding employment gain means residents will have to travel to and from work on an already congested roadway. The EIS will explore regional transportation options mainly on I-25 in Northern Colorado, and perhaps also US 85 and US 287. The eastern boundary of the study area will be the US 85 corridor, and the western boundary will be the US 287 corridor.
Q: How long will the study take to complete?
A: We expect to complete the final Environmental Impact Statement in Fall 2010 with a record of decision in spring 2011.
Q: How will public input influence the statement?
A: Public input will help those conducting the study learn how residents and travelers in the area feel about existing and future transportation needs, alternatives that should be examined, and issues to address.
Q: How soon after the study is complete can we expect to see construction activity?
A: This process will determine whether transportation infrastructure improvements are necessary. If improvements are found to be necessary, the start of construction may be years away, dependant on many factors including the allocation of state and federal funding. However, this process must be completed before funds can be allocated and construction can begin.
Q: Are public meetings the only opportunity to comment?
A: Public input is not limited to public meetings. The team will accept input in all forms including letters, comments submitted to the Web site, and comment cards completed at public events and small meetings with civic, business and community groups. If you would like a presentation at a civic, business or community group, please contact Carol Parr at (970) 350-2170 or Long Nguyen at (970) 622-1280.

Environmental Impact Statement Process
For major transportation projects, the National Environmental Policy Act (NEPA) requires that a range of alternatives be considered and that their environmental impacts be analyzed. This type of study is required prior to the commitment of federal funds to any major project, or prior to any action taken by a federal agency that might cause a significant impact on the environment.
The North I-25 Environmental Impact Statement is led by the Federal Highway Administration. Basic steps in this process include:
- Scoping: A public process to help define the purpose and need for the proposed action or project and to identify environmental issues that need to be studied.
- Data Collection: Collecting transportation, environmental and land use data. This step will also include developing a tool for predicting future
(year 2035) travel. - Development of Alternatives: Identifying a wide range of highway, transit and other types of alternatives, then narrowing these to the reasonable range of alternatives for detailed study. This will include a
"No-Action" Alternative. - Analysis of Alternatives: Transportation, social, economic and environmental impacts of a reasonable range of alternatives are studied in detail and comparisons are made.
- Preparation of a Draft Environmental Impact Statement (DEIS): A printed report for public review and comment is prepared documenting the need for the project, describing alternative courses of action, analyzing likely impacts from each alternative, and describing any steps to be taken to avoid impacts or minimize harm to the environment.
- Public and Agency Review of the DEIS.
- Preparation of a Final Environmental Impact Statement: Documents preferred alternatives and provides response to comments that were made on the DEIS.
- Record of Decision: Documents the decision and commits to mitigation of impacts by the lead federal agency.
The Draft EIS Process
Since early 2006, the North I-25 EIS project team has been diligently working on the Draft Environmental Impact Statement (DEIS). The DEIS is an official document and includes the need for the project, describes alternatives considered, analyzes the environment, social and economic impacts for each alternative, and describe any steps to be taken to minimize, mitigate or avoid impacts. The complete DEIS process includes the following:
Step 1 - Development of DEIS Alternatives – Complete
The alternatives that remained after Level Three Screening were defined with a greater level of detail so that a full analysis can be completed. This greater level of detail includes:
|
|
Step 2 - Analysis of DEIS Packages – Complete
The two DEIS Packages and the No-Action Alternative will be fully analyzed, according to such areas as:
|
|
Step 3 - Documenting the DEIS Chapters – Complete
The information developed throughout the entire study will be documented in a federally required report. This will include:
|
|
Step 4 - Review Process – Complete
The Draft EIS document is reviewed in detail by the several divisions of CDOT, Federal Highway Administration (FHWA), Federal Transit Authority Administration (FTA) and several cooperating agencies (RTD, US Army Corps of Engineers, Federal Railroad Administration). Comments and recommendations from these agencies are then incorporated into the document. Local agencies will receive three months to review the document and provide comment on details in their area and the alternatives as a whole. The final version of the Draft EIS will be signed by CDOT, FHWA and FTA and made available for public review.
Step 5 – Public Comment Period –
(October 31-December 30, 2008) -- Complete
The DEIS public comment period lasts 60 days. Community members that are interested in reviewing and commenting on the DEIS can view hard copies of the document at specific city buildings and libraries or on the project Web site. During this time, the project team will host a series of public hearings to receive input on the DEIS and gather public comments. The comments provided by community members and other interested parties are considered and documented for incorporation into the Final EIS document.
Step 6: Evaluation to Develop Preferred Alternative
During the public comment period, the project team received 1,129 comments from interested citizens and agencies. We are now reviewing those comments and responding as appropriate. Although the formal public comment period for the Draft EIS is complete, the project team still welcomes questions and input from interested citizens. The project team continues to work with the project committees to define a preferred alternative, which we expect to announce this summer.
