Once complete, the new community will boast modern amenities to serve the 1,800 new homes and acres of new park spaces. The first 200 homes will begin presale next month and have spurred the interest of more than 14,000 people. “A year from now you’ll look at this and a lot of the landscaping will be in, the streets will be in, we’ll actually have closings by the end of this year with families moving and starting their lives with 3Roots, which we’re very, very excited about,” said Robby Thorne, CEO of California West Communities.
