roneil@theunion.com The Board of Supervisors on Tuesday approved $500,000 of funding to leverage $3.85 million in private dollars on behalf of four last-mile broadband projects. Sierra Business Council Project Manager Kari Sinoff said the county money will facilitate around 440 connections through grants awarded to Nevada County Fiber, Inc.; Northern Sierra Broadband; and Spiral Fiber, Inc., all in western county; and Oasis Broadband, in eastern county. The timeline for all the projects is 12 to 18 months. “Most of the projects actually require under 12 months,” Sinoff said. “We want to under-promise, over-deliver to residents in this area. They’ve waited a long time for the service, so we want to let them know it will be installed when it will be installed.”
