The Northgate Centre Marketplace should be finished by October but has filled up so quickly with tenants such as Trader Joe's and REI that developers hope to break ground next spring for a second, larger phase of the project.

"We're super happy with phase one," said Ryan McNamara, investment manager with Regency Centers Corp., which has built 207 shopping centers across the country with a combined investment of $3 billion. The publicly traded company owns and manages a total of 365 retail centers.

Eleven businesses have signed leases for the center on Medford's north side, filling up all but 4,000 square feet of the 80,000 square feet of retail space in the first phase.

McNamara said anchor tenants Trader Joe's and REI will open for business in October, with a grand opening scheduled for early November.

Regency is already working with other potential tenants for the second phase of Northgate. Depending on how many tenants sign up, Regency could build from 100,000 to 150,000 square feet starting next spring.

McNamara said Regency has signed confidentiality agreements with tenants, so he couldn't disclose any names.

McNamara said he anticipates Regency will build out the shopping center in two more phases.

"If we had the tenants and all numbers worked out, we would build out right now," he said.
