From UDOT:  Once the public comment period has ended, UDOT will consider all comments received on the Final EIS when deciding which alternative and sub-alternatives are selected in the Record of Decision (ROD).

The ROD, as the next and final step in the EIS process, will identify the final alternative and is anticipated to be issued in the winter of 2022/2023. Implementation of the selected alternative may only occur after the ROD is issued and when federal, state and/or private funding is identified.

Here is what I submitted just now.  

I represent both Big and Little Cottonwood Canyon in the Utah House of Representatives.  As I have conducted a listening tour through our district this summer and met with thousands of my neighbors at their doors, I can confidently state that I represent our district in the following comments.
I support increased and improved bus service, tolling or restrictions on single occupancy vehicles, and the construction of mobility hubs, as described in the phased implementation.
With my constituents, I am opposed to Gondola B.  I have heard that the EIS was never intended to be a popularity poll, but the views of the people who live in and around the canyons should be given high consideration.
The FEIS doesn’t address goals of the Central Wasatch Commission Pillars statement, it doesn’t spend tax dollars in ways that benefit all Utahns, and it doesn’t protect the iconic beauty of Little Cottonwood Canyon.
As a district, we support the Pillars Statement issued by the Central Wasatch Commission in 2021. “The opinion considers visitor use capacity, watershed protection, traffic demand management and parking strategies, a year-round transit service, and integration into the broader regional transportation network, as well as the overall and long-term goal of protection of critical areas in the Central Wasatch Mountains through federal legislation, the Central Wasatch National Conservation and Recreation Area Act (CWNCRA).”
The FEIS fails to adequately address traffic demand management and parking strategies, year-round transit service and integration into the broader regional transportation network, as well as the overall and long-term goal of protection of critical areas in the Central Wasatch Mountains.
The FEIS fails to take account of improvements to traffic flow with parking reservation system at Alta Ski Resort.  The 2,500 parking structure at the base station would exacerbate traffic flow along S.R. 210 rather than reduce the traffic, which could be achieved through transit hubs, which are now under study by Central Wasatch Commission.
It fails to provide a depiction of the impacts to the viewshed in Alta itself.  The supporting structures would require illumination at night, according to FAA, forever changing another unique characteristic of the pristine nature of the canyon.  It would disturb 0.63 acres of an archaeological site and has no clarification for the site of a new bus stop.  There is no plan to provide facilities needed to absorb the thousands of people disembarking from the gondola, ignoring obvious further development to accommodate this change in flow of users.  It is not scalable or flexible, which is a high priority given the lower accumulations of snow the area is experiencing, and would permanently scar and negatively impact the beautiful area it is intended to service. 
The people of Utah will not adequately benefit from the more than $500 million (in 2020 dollars) which will specifically benefit two ski resorts and the tiny percentage of Utahns who ski there.  The problem it addresses involves 20-40 high usage snow days in the winter, but the visual impact would be felt by all users of the canyons year-round.
The FEIS also doesn’t adequately address the superfund site which will be impacted and will potentially require costly mitigation where the parking structure would be sited. 
I join Margaret Bourke of Alta in her request for immediate steps to:

1. Enact for LCC winter-long vehicle traction mandates for all-wheel or four-wheel drive vehicles with appropriate winter tires.
2. Position snow plows up canyon to remove snow rapidly when it falls;
3. Provide flexible, scalable transit year-round into LCC.

Little Cottonwood Canyon is a unique, alpine wilderness.  Any EIS should make protection of its current attributes the highest priority.
