Document Description
The project will remove the existing 48 inch corrugated metal pipe (CMP) culverts, asphalt and debris from the project site and dispose of it in a permitted manner. Excavated soils will be stockpiled and re-used to backfill the trenches after the new high density polyethylene (HDPE) culverts are installed. Two of the replacement culverts will be the same length; one will be longer than the existing. All will be shifted slightly upstream to correct shotgun placement and decrease erosive discharges. Rock slope protection (rip rap) will be placed around culvert ends to protect the new structures from erosion and stabilize adjacent banks. A head wall will be constructed at one of the locations (Front Street). The repaired culvert crossings will be re-paved. All work will be conducted from the adjacent roadway. Vegetation removal will be kept to the minimum feasible. It would not be practical to attempt to remove non-native species and replant with natives due to predominance of invasive non-native species in the surrounding area. Any re-planting is likely to be out-competed by adjacent vegetation (ivy and/or blackberry). A full tree canopy already exists at all three culvert sites. Disturbed soil surfaces will be stabilized with appropriate erosion control measures, including use of erosion control fabric or turb reinforcement mat and seeding with a native grass mix.
