City Council At-Large Position 1



Council Member Stephen Costello


Stephen Costello is in his third term as a Houston City Council Member (At-Large Position 1). He chairs City Council's Budget and Fiscal Affairs Committee and serves on the following additional council committees: Quality of Life; Transportation, Technology and Infrastructure; Ethics, Elections and Council Governance.


As vice chair of the Transportation Policy Council of the Houston-Galveston Area Council, he provides policy guidance and overall coordination of the transportation planning activities within the region.


Stephen is an engineer with a background in flood control and drainage. He is co-founder and president of Costello Inc., a Houston civil engineering firm named repeatedly as one of the “best places to work” by the Houston Business Journal. With a degree in civil engineering from the University of New York at Buffalo, Stephen's first job out of college was working as a civilian with the U.S. Army Corps of Engineers in Galveston. It was with the Corps that Stephen discovered his lifelong interest in storm water management and flooding issues after working with residents whose homes had been flooded. That led Stephen to work for the passage of the ReBuild Houston program, which will address the city's drainage and flooding issues with funds set aside for that purpose only.


As an authority on flooding and storm water management, Stephen has served as an expert witness for Harris County and TxDOT on drainage related issues. His depth of experience has been sought out by governmental agencies including large and small municipalities, county and state governments. In addition, Stephen has helped to create and rewrite criteria manuals for the Harris County Flood Control District, Harris County and the City of Houston.


Stephen has served as chair and longtime board member of the Memorial Park Conservancy, a nonprofit organization dedicated to preserving the natural habitat and historical significance of Memorial Park.  He is also a board member for Marathon Kids, an organization which helps educate and motivate children to lead active lifestyles and Family Services of Greater Houston, an organization that provides counseling services to families and individuals. In addition to these great organizations, Stephen serves as an advisory board member for Trees for Houston, a nonprofit that seeks to protect woodlands and plant trees around the city.


Stephen and his wife Debbie have raised two sons in Houston. On City Council, Stephen is focusing on issues related to: improving the city’s long-term financial health; increasing access to fresh, healthy food in underserved communities; upgrading and maintaining the city’s aging infrastructure; and improving transportation and mobility.
