National Environmental Policy Act (NEPA)
Phase 1 of the Iowa City Gateway project was the completion of a federally required planning process called for in the National Environmental Policy Act, or NEPA. NEPA is required for projects that will seek federal funds and/or federal permits.Through that process, the team evaluated how various design alternatives impact the Iowa River and its floodplain, as well as impacts to nearby properties and community resources. Phase 1 included many opportunities for community input and was completed at the end of 2013. (Required reviews from state and federal agencies extended the original schedule.) Phase 1 recommended an approach for improvements call the Preferred Alternative.
Beyond legal requirements, however, the NEPA process helps governmental agencies and local communities make well-informed decisions about future projects. Additionally, the process gives the community (1) access to information used by agencies in selecting a preferred alternative and (2) a chance to have input into those public decisions. The NEPA process requires that the following questions be answered before they receive federal approval:
- What is the problem? What is needed? The study’s Purpose and Need serves as a guide throughout the evaluation process.
- How might the improvement impact the natural environment like water, air and threatened and endangered species?
- How might the improvement project impact neighborhoods and businesses? How would historic or archaeological sites be impacted? How would economically disadvantaged groups be affected?
- How would the proposed improvement work? Does it address the Purpose and Need? What will it cost construct and to maintain
Following federal approval of the NEPA document, detailed design work began in the summer of 2014. Phase 2 was completed in February of 2016 with the submittal of final plans to the Iowa Department of Transportation (DOT).

Public Hearing and EA recommendations - April 4, 2013
The April 4 Iowa City Gateway public hearing included a drop-in center from 4:30 to 6 p.m., and a formal presentation and question and answer session at 6:30 p.m. At the meeting, the roughly 45 attendees had an opportunity to learn about the project process and provide input regarding the Environmental Assessment (EA) document, the preferred alternative, and corridor needs. The attendees could also ask questions of the design team and City staff, see a short presentation about the project and provide formal comments about the recommendations in the EA.
Preliminary alternatives - November and December, 2011
Because of wide public interest in the project, the City of Iowa City added an additional opportunity for the community to review and provide input into draft alternatives. The alternatives were posted on the project website on November 25, and visitors to the website were provided with a link to provide comments through December 30, in addition to submitting comments directly via the project website. For those who wanted to review maps, ask questions or submit comments in person, Iowa City hosted a drop-in center from 3:30 to 7 p.m. on Thursday, December 8, 2011 at the Robert A. Lee Community Center in Iowa City.

February 26, 2014
Pre-Design Meeting: The Conceptual Design for improvements to Dubuque Street and replacement of the Park Road Bridge has been revised, based on design parameters established by the City Council in January, 2014.
Thanks to the nearly 100 people who participated in the Drop-In Center on February 25.
The conceptual design shows the new, reduced footprint of the project, based on council direction from January, 2014.
January 23, 2014
On January 21, 2014, the City Council discussed the project during the informal work session and approved design parameters for the Iowa City Gateway Project at the formal meeting. Those primary design parameters for the project are: Protection level for Dubuque Street will be the 100-year flood elevation plus one foot, Backwater Reduction Goal (low steel elevation) for the Park Road Bridge will be the 200-year flood elevation plus one foot and the structural type for the bridge will be a Through Arch.
The primary design parameters for the project are:
Protection level for Dubuque Street will be the 100-year flood elevation plus one foot.
Backwater Reduction Goal (low steel elevation for the Park Road Bridge will be the 200-year flood elevation plus one foot.
The structural type for the bridge will be a Through Arch.
January 17, 2014
The public was invited to attend the January 21, 2014 City Council meeting. A brief presentation was made at the 5 p.m. work session, followed by City Council questions and project discussion. A resolution has been placed on the Agenda for the 7 p.m. City Council Meeting. The City Council is being asked to establish the following three design parameters: (1) the level of protection for Dubuque Street, (2) the backwater reduction goal (elevation of the Park Road Bridge), and (3) the structural type of the bridge. City staff has recommended that the design parameters be: (1) protect Dubuque Street to the 2008 flood elevation plus one foot and, (2) provide backwater reduction by elevating the low steel of the new bridge to the 200-year flood plus one foot and, (3) proceed with either the Through Arch Bridge or the Deck Girder Bridge. The public will be able to comment during the discussion of the Agenda item.
December 19, 2013
The City of Iowa City has received notification from the Iowa Department of Transportation that the Federal Highway Administration (FHWA) has approved and signed the Finding of No Significant Impact (FONSI) for the Iowa City Gateway Project. The approval was dated December 18, 2013. The FONSI is the final step in the National Environmental Policy Act (NEPA) process. The project is now cleared to move forward in the design process.
Design parameters for the Gateway Project was discussed by the City Council on January 21, 2014.
November, 2013 Update
At the request of the Iowa Department of Transportation (DOT), the Finding of No Significant Impact (FONSI) document has been submitted for review. The Iowa DOT will review the document and then submit it to the Federal Highway Administration (FHWA) for final review and approval. Federal approval of the FONSI represents the final step in the National Environmental Policy Act (NEPA) process.
At this time, Iowa City has not been made aware of a final resolution to the Section 106 process requests made by the Advisory Council on Historic Preservation (ACHP) to the FHWA.
City Council Review
The Iowa City Council is in the process of reviewing the project to establish parameters for design. At a work session on September 17, 2013 the Council heard a presentation from city staff and the design consultant. An overview of the Environmental Assessment/NEPA process and the Preferred Alternative was given before moving on to discuss the Design Decisions that will need to be made by the City Council prior to final design and engineering. These decisions include: the level of protection for Dubuque Street, backwater reduction goals and structural type of the bridge.
A range of options was provided and, based on preliminary design information, cost estimates, roadway elevations and water surface elevations were provided. The “Do Nothing” option was addressed as well, which includes many needed improvements to the aging infrastructure in the corridor.
The City Council continued to review the Iowa City Gateway project at their October 1, 2013 work session. That same night, there was an agenda item for public input on the project at the 7 p.m. formal Council meeting. Staff outlined recommendations in a presentation and then opened the floor for public comment. Additionally, staff made note of questions from the public and will follow up with discussion and responses in a future council information packet/session.
Environmental Assessment Review Status
The Federal Highway Administration has indicated that their process for responding to the Advisory Council on Historic Preservation will not be complete prior to the October 1 City Council meeting. Formal council action regarding design parameters will not occur until after the NEPA process is complete.
The Iowa City Gateway Environmental Assessment
The City of Iowa City has studied potential solutions to minimize flood impacts on Dubuque Street and Park Road, reduce backwater created by Park Road Bridge and make needed infrastructure improvements in the corridor.
Recommendations for those improvements, as well as potential adverse and beneficial impacts to the community, buildings and the natural environment are detailed in the Iowa City Gateway Environmental Assessment (EA).
