The Phoenix Award executive committee announced that Lafarge North America won the 2005 Phoenix Award for EPA Region 6, one of the 10 EPA regions. The award recognized Lafarge, along with the site's developer, Morning Park, Inc., for their cleanup, redevelopment, and revitalization of an 888-acre industrial site in South Dallas, Texas. Lafarge, along with Morning Park, The RETEC Group, and the Christon Company were honored at a Denver awards ceremony in early November.

The company transformed the former cement plant and limestone quarry into a mixed-use community called Pinnacle Park. By 2005, the development brought in more than 7,000 jobs to the impoverished area and increased the city and county's tax base by $35 million.

Beginning in 1901, the Lafarge plant and quarry brought jobs to Dallas citizens during some of the most challenging economic times. However, the plant closed in 1987, and Lafarge donated a portion of the property where their landfills sat to the city for redevelopment as parks and ball fields. After the plant's demolition, the 888-acre redevelopment project took shape.

Created in 1997, the Phoenix Award honors individuals and groups who are working to solve the critical environmental challenge of transforming abandoned industrial areas into productive new uses.
