The Metro Council on Tuesday approved a novel plan to finance more than $18 million in infrastructure improvements that will help prepare more than 1,000 Bellevue acres for development. A Texas firm's plan for Biltmore Ridges calls for more than $300 million of investment over time, but Metro Public Works has said various infrastructure projects need to be completed along the way. They will be funded by developments in the Biltmore Ridges footprint.
