The Dallas Morning News » Dallas Mayor Mike Rawlings wants a new group with a “single-minded focus” to make a long-awaited park along the Trinity River a reality. Next week, officials will brief the City Council on a plan to create a “local government corporation” to take on the Trinity River park project. The public-private partnership would be responsible for working out the details of planning and building the new park, which would span 200 acres between the Margaret McDermott Bridge and the Ron Kirk Bridge.
