Newgate Drive Channel Repair (Upstream) - City of Johnston

The stream corridor along the south side of Newgate Drive is generally classified as moderately unstable, with steep slopes and heavy wooded debris. A number of storm sewer outlets have been undercut by excessive erosion over time. The corridor lacks a natural system of riffles and pools and sustains little quality habitat along its length, effectively acting as only a large urban storm sewer. This first project would fix the most urgent area of this project located north of Lenham Drive where the erosion is the worst and where it's in closest proximity to structures and public improvements. This project would include a stilling basin at the outlet of a major storm sewer pipe and two riffle/let down structures. The project is included in the city's 2022-2027 Capital Improvement Program (CIP). As of December 14, 2022, further details regarding design and construction have not been identified.* *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change.
