In the second letter, which he characterized as the city's formal comments on the EIS, Hahn raised concerns about the contents of the most recent version of the document.
In her response, Hammond noted the history SDOT and WSDOT have of working together over the last nine years and says she sees no reason to redefine the state and city's respective roles. And she said the state has no authority to say who is "required" to sign the FEIS for the city.
In your December 2 letter, it appears that you are asking us to define who the designated city official is for the City of Seattle. However, it is the City's responsibility to determine who within its own government will sign such documents. Neither WSDOT nor the [Federal Highway Administration] dictates to another government or agency who will sign for them; that would be far outside our agency's jurisdiction.
Hammond also told Hahn she believes it's inappropriate for the city to submit formal comments raising objections to aspects of the EIS, since the city is a partner on the project. "As a co-lead agency, you have been providing your comments, and WSDOT has adjusted the documents accordingly throughout the preparation of the environmental documents."
