DANVILLE -- Talks are under way with several high-end retail stores and other potential tenants of the up-and-coming Navlet's/Rose Garden Shopping Center, where one luxury day spa already has signed a lease, the projects chief developer said Tuesday. Were very pleased with the quality and type of tenants that were having various levels of discussions with, said developer Brad Blake, whose company, Blake Hunt Ventures, along with Castle Companies of San Ramon, is developing Navlet's/Rose Garden.

Because of the size and quality of their operation, we really view (Burke Williams Day Spa) as an anchor-type tenant for our project. We really think they have the ability to attract other higher-profile retail and restaurants.

Construction has not yet begun on the planned 114,766-square-foot office, shopping and apartment complex on 10 acres at Sycamore Valley Road and Camino Ramon. It is still at least a year from completion.

But a number of high-quality shops and restaurants already are interested in renting space, spurred on by the news that a popular day spa will be joining the shopping center, Blake said.

The Burke Williams Day Spa, which operates seven spa locations in Southern California, has signed a 10-year lease to occupy about 18,000 square feet on the second floor of the shopping center, which originally was intended for office space. The remaining 10,600 square feet on the second story will host offices.

Danville's planning commission last month approved a zoning change to allow for the spa, citing no anticipated impacts on traffic or circulation.

The (number of parking spaces) is still well within what's typical for a shopping center, city planner David Crompton said.

Traffic and parking were among a laundry list of concerns aired by dozens of opponents of the project when it first was presented to Danville planners about two years ago.

The 19-year-old privately owned Burke Williams group began its Northern California push about three years ago with the opening of a spa in San Jose, Burke Williams marketing director Terry Shofron said.

The company offers a variety of services including massage, hair, nails, facials and wraps, with individual services starting in the $120 range.

Another Burke Williams spa is due to open in late September in the Bloomingdale's shopping complex in San Francisco.

"Obviously, we are a high-end spa, so (we go to areas) where people can afford our services," Shofron said. "We're looking at capitalizing and getting our name out in the Northern California market."

Grading has begun on the project, with construction expected to begin within the next couple of weeks.
