• Abstract:
  The Texas Pollutant Discharge Elimination System (TPDES), which is administered and enforced by the ; Texas Commission on Environmental Quality (TCEQ), requires perennial vegetation to 70 percent of native ; or adjacent background vegetation before a Notice of Termination (NOT) can be filed. The Texas ; Department of Transportation's (TxDOT) roadway projects often terminate at times of the year when ; establishing permanent vegetation is very difficult or nearly impossible. Even when the construction calendar ; and the ideal growing season line up, establishing vegetation is still a constant challenge. Regions of the ; state that have limited rainfall and a shorter growing season often take multiple years to establish vegetation ; to meet the TPDES requirements. ; The objective of this study was to provide a more diverse set of tools and options for TxDOT personnel that ; will help ensure timely vegetation establishment to meet the TPDES regulatory requirements, minimize ; project delays, and help reduce long-term costs in vegetation development and management. To achieve ; these objectives, the researchers: (1) compared TxDOT’s practices compare to those of other state ; departments of transportation (DOTs) and related fields, (2) identified methods for more rapid vegetation ; establishment for meeting the TPDES requirements using field demonstration plots seeded according to ; current TxDOT practices, (3) devised a tool to assist design personnel not familiar with the vegetation ; establishment process, and (4) developed a vegetation establishment field guidebook.
