7/13/23 - A Thank you from Susan Dell'Osso

I would like to thank all the River Islands residents who attended the Town Hall meeting last night.  I definitely heard your concerns and am taking them very seriously.  Please give our team a few weeks to develop some plans and responses.  I appreciate your input and look forward to continuing the dialog.

The Islanders' Circle

Have you popped open the bottle of Priest Ranch Wine that was included in your River Islands welcome basket and LOVED it? Here's some great news:

Priest Ranch, which shares a parent company with River Islands, has created a wine club just for Islanders, with plans for deliveries to be made to our community three times per year, accompanied by fun
pick-up parties! 
Along with a special discount on all wines, members will receive three customizable shipments per year, be invited to the tasting room in Yountville for a complementary wine tasting once a year, first-access to winery-exclusive wines and MORE!

Want to have a picnic with your family or enjoy the recreational sports areas for an afternoon? The City of Lathrop's guidelines make neighborhood parks within River Islands available to residents on a first come, first serve basis.

Although there aren't any dedicated areas within the community that can be reserved on a regularly-scheduled basis, here are some things to keep in mind:

  • Neighborhood parks are intended for walk-up use by residents.

  • Fire Station #35 at 19001 Somerston Pkwy has a community room available upon request. The Lathrop Police Department building also has a community room.


To review the formal guidelines, please click here.


When you meet someone who tells you they live in Drake’s Bend, do you know where that is? Did you know that Lakeside is not 360 Lakeside? Wouldn’t you love to have a map that shows all of the River Islands neighborhoods, by name?


This is not a street map, but a neighborhood map, to help you navigate around the community as you put down roots.
