River Islands is in the process of securing its first supermarket.

It will be a 55,000-square-foot market.

And once the deal is completed, River Islands CEO Susan Dell’Osso noted there are a number of smaller retail and service concerns that have expressed high interest in securing space in the planned community’s town square.

Dell’0sso said River Islands won’t be signing any secondary tenants until such time the supermarket deal has been finalized.

It’s little wonder interest is high.

The overall community of 4,000 homes so far has a median household income of just under $120,000. River Islands is planned for 15,001 homes overall.

Based on the per house yield factor of 3.8 people, there are more than 15,000 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.

River Islands is also working with Sutter Health to site a medical clinic in the community.
