A more than $100 million Oceanside housing development that started construction in August will have 301 homes in a mix that targets middle-income buyers.

Melrose Heights is being built by Trumark Homes based in San Ramon on a 70-acre site at the corner of Melrose Drive and Oceanside Boulevard at Oceanside’s border with Vista.

Trumark Homes is a subsidiary of the Japanese firm, Daiwa Housing Group.

The Oceanside project will have four separate neighborhoods and include 20,000 square feet of commercial space and a 34-acre nature preserve that wraps around part of the site.
