Replacement of the listed RCPs, CMPs, and sewers; and grading and relining the open channel reaches. The RCPs and CMPs will be replaced in place with new twin parallel 36-inch RCPs. The new culverts will include a headwall and wingwalls at each end for bank stability. The sanitary sewer laterals and cleanouts will be replaced in accordance with the City of Raleigh Public Utilities Department's standards.
