Clarence has represented municipal interests for over twenty-five years. As a former City Attorney of the City of Houston he is familiar with both the operational and practical issues of a governmental entity. Since leaving the City of Houston he has represented municipalities throughout the nation.

His practice has focused on municipal legal issues concerning compensation and use of the public rights-of-ways, including telecommunication, cable television, gas and electric franchises, and rights-of-way management ordinances.

In 1999 a number of his client cities formed a coalition to participate at the PUCT in the implementation of House Bill 1777 (Chapter 283), regarding telecommunications franchise fees and management of rights-of way issues. That Coalition continues to participate in the various Rulemakings and PUCT projects involving Chapter 283. In 2005, on behalf of the Coalition, Clarence actively participated in the negotiations at the Texas legislature on SB 5, the state-issued cable and video services franchising bill, which added Chapter 66 to the Utilities Code. In 2011, he again participated in the negotiations on amendments to Chapter 66 by SB 1087. He has provided expert testimony on these issues numerous times before Texas legislative committees. He also serves as general counsel to a group of cities that purchase power under the deregulated power market in Texas.
