The Elk Grove council's vote in favor of the Silverado Village project means about 650 homes will be going up on over better than 200 acres of land.
People living nearby telling councilmembers they're worried about a number things like added noise and environment issues, but the biggest concern is with the water supply.
Existing residents are being forced to conserve water, so they question the decision to add even more demand on the existing water supply.
City officials insist a supply study shows there's enough water to support the Silverado Village project's more energy and water efficient homes.
They also point out that the project will create jobs and pull in more tax dollars.
