How Big Sky Ranch was planned
In 1999 the City circulated a draft environmental review for Big Sky Ranch: a proposal to subdivide the site for 648 detached homes, 21 estate homes and 265 attached homes, with Madera Road built across the site and Erringer Road extended north to meet it. Census road maps today show Madera Road ending more than a mile west of the outline. Ask the City’s Planning Division which tract map and conditions apply to a lot.
Next door: the Lost Canyons approval
A Notice of Determination the City filed with the State Clearinghouse lists the Lost Canyons project as approved on August 10, 2026. As the City describes it, 362 lots would cluster north of Lost Canyons Drive, where the Shadow Canyon Golf Course operated, with a private recreation building and public trails instead of a new course. Its May 2026 addendum puts the nearest homes, in Glenmeadow, about 150 feet west of the site, expects construction to begin in 2026, and limits heavily loaded construction trucks to Tapo Canyon Road and Lost Canyons Drive. Track the build under new construction in Simi Valley.
