Once complete, the 185,000 square feet in additional shopping space is expected to generate about $146,000 in property tax revenue and between $687,000 and $702,000 in sales tax revenue, said City Manager Stephen Dunn.
The first tax revenues are expected to roll in during the 2013-14 fiscal year, he said.
"Most of it will be when construction is complete which will be by December 2013," he said.
The city is currently reviewing ways to cut more than $2 million from the general fund budget annually.
Councilman Ken Willis said the revenue from the new phase will not be a "saving grace" as the first phase was, but it will help alleviate some of the city's current financial problems.
"It'll be important to the city. It won't bail out the boat completely, but it will certainly do some bailing out for us financially," he said.
The 400-acre commercial and residential development currently provides more than $3 million in tax revenue to the city annually, he said.
"We're proud the difference it made for Upland," said Dan Richards, co-managing partner of the Colonies Partners LP.
Stores are expected to start opening in early spring, with Nordstrom Rack, and will continue to open in phases throughout 2013.
An Arco gas station and AM/PM mini mart will open above the 2010 Freeway on Campus Avenue in three to four months.
T.J. Maxx, Toys R Us and Babies R Us will be some of the first to open after Nordstrom Rack. The developer is working on the final details on leases with Famous Footwear, Tilly's, G Stage and BevMo.
They are still in negotiations with several national retailers for a 25,000-square-foot building, Richards said.
The new phase of development will include a food court that will open in summer/fall on the corner of 19th Street and Campus Avenue.
Panera Bread, Pick Up Stix, Chipotle and The Habit Burger Grill have signed on.
Talks with sit-down restaurants are also in the works, Richards said.
"We've worked really, really hard to develop a project that was going to be well-received by our community," Richards said.
The first phase of the development opened in 2005 with anchor stores Target, Kohl's, Bed Bath & Beyond, Home Depot and Albertsons.
The shopping center is near 100 percent capacity, Richards said.
"We're very fortunate and thankful and I mean for the quality of tenants that we have and numbers of them," Richards said.
Shoppers can also expect more retail and residential properties to be built in the development in the future.
There is commercial space still available north of the 210 freeway and along Campus Avenue.
Additional residential units have already been approved by the city.
"I think we are the largest commercial development under construction in Southern California and in little ole' Upland," Richards said. "It speaks well for the project and community."
