Current Activity

Necessary permits from the US Army Corps of Engineers (USACE) have been acquired for this project. Advertisement for the project's construction bid is expected to occur in Winter 2018.

Summary

The goal of the project is to improve this area's watershed by repairing and stabilizing eroded creek banks, which improves water quality, wildlife habitat, and enhance community aesthetics.

The project involves re-establishing and stabilizing over 1,000 feet of an un-named stream to Mine Creek that flows south beneath Sawmill Road in north Raleigh. This work includes: temporarily closing a City greenway, removing trees (to provide sunlight and a clear work space), installing erosion control measures, grading severely eroded creek banks, installing grade control (natural stone) structures, planting native plants (trees, shrubs, and plugs), and reseeding.

History

This undeveloped city parcel located south of Sawmill Road was identified for a stream stabilization several years ago. A previous property owner built an earthen dam, which failed altering the natural flow of the stream. The objective of the project is to re-establish the natural flow and stabilize the stream banks. This will improve the overall water quality of this watershed within the Crabtree Basin by stabilizing severely eroded stream banks and improving wildlife habitat that has been impacted by sediment pollution.
