State construction inspectors have given the thumbs-up of approval to a series of roadside improvements in several areas around Oahu. The completed Slope Improvements for Erosion Control Phase 5 projects included the repair of 11 eroded slopes and one eroded outfall located in the State of Hawaii Department of Transportation Highways Division’s (DOT-HWYS) rights-of-way. The $2.6 million project began in early 2013 and the final site was completed in early 2014. In June 2015, one-year follow-up site inspections were completed to verify that the repaired erosion sites remained stable with adequate grass and plant growth. These stabilized sites will significantly reduce sediment runoff into the DOT-HWYS storm water system, and help ensure that the DOT-HWYS meets its goals of reducing storm water pollution.
