PROJECT SUMMARY
Ellerbe Creek - Hillandale Golf Course
Location: Durham NC
Project Size: 6279 linear feet - Stream Restoration
Watershed Area: 3.4 square miles (2150 acres)
River Basin: Neuse - Cataloging Unit 03020201
Background and Ellerbe Creek at Hillandale Golf Course was first identified for stream restoration by
Goals: local stakeholders and EEP during the early phase of EEP's Local Watershed Plan
development for the Ellerbe Creek watershed. This stretch of Ellerbe Creek exhibited typical
urban stream problems associated with past channelization efforts by USACE, increased
stormwater runoff, and loss of streamside vegetation. The degraded stream was characterized
by excess sediment loading (from slumping, eroding banks), deep entrenchment, and poor
aquatic habitat. In addition, Ellerbe Creek was an EPA 303d-listed stream due to its overall
degraded water quality.
EEP completed the construction phase of the restoration in March 2005. Following the
natural channel design approach, the restoration increased channel sinuosity, established a
floodplain bench, stabilized the banks, improved channel bed profile, and re-established a
vegetated riparian buffer. The goals & objectives of the restoration project focused on
improving water quality, enhancing flood attenuation, and restoring aquatic habitat and the
riparian buffer. Successful completion of this project, coupled with other restoration efforts
in the watershed, will help achieve these goals on a broader, watershed-wide level.
Project Goals:
• Provide a stable stream channel
• Improve water quality
• Reestablish the stream's capacity to efficiently transport watershed flows
• Reconnect the stream a new floodplain at a lower elevation
• Improve aquatic & terrestrial habitat and biological integrity of the system
• Incorporate stormwater BMPs to treat urban runoff into the stream
• Establish riparian zone using native vegetation
Status of Project: 2.d Year Monitoring (Construction completed in March 2005)
