Construction will begin next week on the Waterside development in southwest Fort Worth, to include a Whole Foods Market and a 375-unit multifamily community, now that the developer has purchased the land. Fort Worth-based Trademark Property Co., in partnership with Sarofin Realty Advisors in Dallas, has closed on the purchase of 63 acres along the Trinity River at Bryant Irvin Road and Arborlawn Drive from the Bryant Irvin Recreation Complex, formerly the Lockheed Martin Recreation Association.
