Though many "For Lease" signs still dot the streets and avenues of Rancho Bernardo's shopping downtown, tenants and developers are scoring deals that mean storefronts are starting to fill up again.

Retail spaces in North San Diego and Southwest Riverside counties are split by class: Top-flight properties visible from major roads, with proximity to grocery stores and pharmacies, attract premium customers, while lesser locations struggle to find tenants.

Up to eight businesses can be added to 4S Ranch Village, which when completed this summer will mean the last construction for that shopping center, according to a center official.

Two buildings going up next to Fresh & Easy will add a combined 11,000-square-feet of shopping space, bringing the center to about 67,000 square feet, said Ann Forella, director of asset management for Buie Stoddard Properties. It owns 4S Ranch Village.

Recent business developments in Rancho Bernardo and 4S Ranch include some closures, openings, expansions and relocations.

The former San Diego National Bank building in Rancho Bernardo has been purchased by Boardwalk Development, Inc. in partnership with James Nierman.

The 14,000 square foot, two-story, building at 16789 Bernardo Center Drive is a former Home Federal Savings branch featuring a brick facade, wood shutters and a balcony. San Diego National Bank purchased the building September 1999 for $2,400,000.

The seller was the FDIC as steward for the failed San Diego National Bank, which was taken over by the FDIC in October 2009. The purchase price was $2,500,000.
