The biggest homesites in River Island's Phase 1 master-planned area, each measuring at least 7,000 square feet, will be found in Trumark Homes' Avalon at River Islands neighborhood in Lathrop, which is next to a sizable park. Avalon will include 57 single-family detached homes with three different designs that range in size from around 2,827 square feet for a single-story to 3,761 to 4,199 square feet for two-story homes, with 2 and 3-car garages, roomy yards, and 3 to 5 bedrooms. These homes have optional lofts, dens, Next-Gen suites, and other features to accommodate different family demands. Homeowners in River Islands in Lathrop have access to facilities including parks, riverside paths, a lot of room for leisure, a collection of STEM- and technology-focused schools, and easy access to shopping malls. Homes in the River Islands master plan are situated in San Joaquin County off of Interstate 5 at E Louise Avenue and provide a central position within a 30-minute commute to 25,000 enterprises in Downtown Stockton and other Bay Area employment locations. The location, which will have its own commercial hubs once it is fully developed, is also close to other shopping malls in Tracy, Lathrop, and Manteca.
