Cisterra Partners, CB Richard Ellis and Trammell Crow Company announce that Comerica Bank has executed a lease for two mid-level floors at DiamondView Tower where the bank will consolidate its San Diego regional banking services, and for a first-floor site of a relocated downtown bank branch.

The15-story building in East Village at the corner of 10th Avenue and J Street will rise just beyond the right-field fence of Petco Park, home of the San Diego Padres. The bank has signage rights, pending city approval, to place the Comerica logo at the top of DiamondView Tower where it will be visible to Petco Park baseball fans.

Cisterra plans to break ground this spring on the 306,700 sq. ft., Class A office tower, with completion expected by January 2007.

Comerica Bank joins Cox Communications as one of the first two major tenants to finalize a lease at DiamondView Tower project.

"We are excited to become a part of the East Village and DiamondView Tower," said Mike Fulton, president and CEO of Comerica Bank’s western division. "DiamondView Tower will signal our expanding presence and confidence in San Diego, allow us to support its growing downtown communities and offer tremendous amenities for our employees and customers."

Comerica currently has offices and a branch in two buildings on B Street in San Diego, and recently opened a new branch in La Jolla.

DiamondView Tower will offer suburban-like parking as well as skybox-type views of the ballpark, San Diego Bay, and the Coronado Bridge. The design includes private balconies on every floor, a 15th-floor conference/entertainment room, 36,000 sq. ft. of first-floor retail amenities, and a free tenant shuttle.

The new building will be located next to the Park at the Park. It is a short walk from the Gaslamp Quarter and mass transit stops, and has easy freeway access.

DiamondView Tower received San Diego City Council approval in November 2004. In December, Cisterra Partners closed acquisition rights with the San Diego Padres for the site and Prudential Real Estate Investors became a partner in the project.

Comerica Bank was represented in this transaction by David Crabb, Herb Hafter, and Craig DeMiranda of Trammell Crow Company. Kraig Kristofferson, Nelson Ackerly and John Gross of CB Richard Ellis represented Cisterra Partners.
