Once River Islands secures its first supermarket, a long-list of retail, dining, and services are expected to quickly fill secondary tenant space.

River Islands CEO Susan Dell’Osso expects the 15,001-home planned community will land what will be its first retail venture in the near future.

Once the 55,000-square-foot supermarket is secured, Cambay Group will move forward with creating commercial space that will be filled by concerns that have expressed high interest in opening on River Islands.

It doesn’t pencil out financially to build secondary tenant space first.

That said, the overall community of 4,200 homes built so far has a median household income of just under $120,000.

Based on the per house yield factor of 3.8 people, there are nearly 16,000 people living in River Islands with the closest convenience store at least 1.5 miles away.

Dell’Osso said in keeping with the River Islands concept, the new supermarket will not be a discount grocer.

Also, the architecture treatment and other site touches will go beyond what one would expect in new shopping centers.

It would give Lathrop its second supermarket per se overall.

The existing supermarket is SaveMart at Interstate 5 and Lathrop Road.

The Lathrop Target at Louise and I-5 has a large grocery department. There is also a Sprouts specialty store in the same shopping center complex

There is a smaller grocer, Delta Market, on Louise Avenue near the tracks.

Lathrop also will be getting a Sam’s Club, Walmart’s answer to the Costco retail and grocery concept.

The new supermarket will go where the current welcome center is and across the street from the new two-story Sutter Health medical officers that are being built.
