The TCEQ requires permit holders of a Municipal Separate Storm Sewer System (MS4) Permit to meet specific minimum control measures including Post Construction Stormwater Management in New Developments and Redevelopments. Some of these requirements scale with the size of a City’s population and since the City of Round Rock is over 100,000 in population, we are required to implement a new program addressing the stormwater structural controls in the City.
