INFORMATION/BACKGROUND
Locust Street and Elm Street are both currently Texas Department of Transportation (TxDOT) roadways.
The Locust Street and Elm Street Water, Wastewater and Drainage Improvements Project was conceived
in order to replace aging infrastructure along Elm and Locust Streets prior to TxDOT resurfacing and
ultimately turning ownership of these streets over to the City of Denton. The water mains and sanitary sewer
improvements for this project will occur between West University Drive to the north and Hickory Street to
the south. Phase I of the storm drain improvements are to determine the flow and culvert design for Elm
Street and Locust Street crossings of North Pecan Creek and Pecan Creek.
Phase II of the storm drain improvements include the completion of the detailed watershed study for North
Pecan Creek and Pecan Creek. The detailed watershed study will facilitate future design and sizing of
crossing structures throughout the watershed.
The purpose of this amendment is to provide funding to address drainage revisions and comments found
during the 90% review process. The amendment will also fund TxDOT permit coordination along with
right-of-way acquisition assistance.
