Grading and land development efforts are underway at Brookfield Residential's new master planned community in San Marco, Calif., which is set to open in the spring of 2017, the company announced Thursday.

The community, Rancho Tesoro, will span more than 250 acres and showcase four neighborhoods -- three behind vehicular gates -- each with unique architectural styles. The 347 detached homes will include private yards, four-to-five bedrooms, and two- to three-car garages. Homes will range in size from approximately 2,211 to 3,565 square feet.

Here’s more from Brookfiled’s release:

"Future residents of Rancho Tesoro will enjoy a true front row seat to nature, as the community will include a direct connection to Discovery Lake for walking and biking, catch-and-release fishing, picnicking, enjoying playgrounds and more," says Mercedes Meserve, vice president of marketing for Brookfield Residential Southern California. "In addition to enjoying the community's scenic location, residents will have easy access to all that the city has to offer, including high-performing schools within the San Marcos School District, as well as nearby Cal State University San Marcos."

"We strive to create the best places to call home and we're confident that Rancho Tesoro's location, thoughtful layout, and home designs will deliver just that," adds Meserve.

Proposed private recreational amenities at Rancho Tesoro include a pool, barbecues, picnic tables, a covered trellis pavilion, neighborhood parks and access to multiple trails for walking, jogging, and bicycling.
