Placer County, California
Placer County runs from Roseville and Rocklin on the Sacramento edge up Interstate 80 through Auburn to the north Tahoe shore at Tahoe City. Roseville's master-planned communities make the west county one of Northern California's most active housing markets, while the Tahoe basin operates under TRPA coverage limits, and fire-hazard zoning and the Placer County Conservation Plan govern the foothills between.
