Statement summary

Announcing the city's state-court lawsuit, Ryan says the project would have a major impact on the neighborhood and the Buffalo River and that any entity developing in Buffalo must account for that impact and be a good neighbor.

“We have a responsibility to protect those investments and the people who live, work, and spend time here. It is incumbent on us to make sure that any entity developing a project in Buffalo understands the impact it will have on the surrounding community and does its part to be a good neighbor.”

Ryan says the planned fuel depot does not fit the Old First Ward and runs against more than a decade of the city's plans for the Ohio Street corridor, as the city demands that the Seneca Nation stop work at the site.

“This is not a good fit for this neighborhood, and it runs counter to the vision we have been building for this corridor for more than a decade”
