Trumark Homes has developed two new home neighborhoods within the River Islands master-planned community in Lathrop, California, one of the most successful master-planned communities in the United States. River Islands offers homeowners amenities such as parks, riverfront trails, significant recreational space, a collection of technology and STEAM-focused schools, and access to retail centers. Avalon and Avalon Point by Trumark Homes offer the largest lots within River Islands and will feature 126 one and two-story homes.

Trumark’s Avalon community is located adjacent to a large park and will offer the largest homesites in the River Island's Phase 1 master-planned area consisting of a minimum of 7,000 square feet each. Avalon offers 57 single-family detached homes in three plans ranging in size from approximately 2,827 square feet for a single-story and 3,761 to 4,191 square feet for two-story homes, with two and three-car garages, generous yards, and three to five bedrooms. These homes are designed to meet families’ differing needs by offering optional lofts, dens, Next-Gen suites, and more.

Trumark’s second neighborhood, Avalon Point, provides the same flexible floor plans as Avalon. The neighborhood is located on the outside edge of the River Islands master plan development and has a park located at the north end of the community. Avalon Point offers 69 single-family detached homes on large lakefront and cul-de-sac homesites with the option to include a second-story balcony off the primary suite on lots backing up to the lake.
