Title

Newman Influent Trunk Sewer Improvements – Phase II

Description

Proposed Phase II improvements consist of approximately 5,125 feet of 36-inch in diameter sewer line and 16 sewer manholes between Canal School Road and the Phase I connection. The connection to Phase I is shown on Sheet C-20 of the project plans and includes an additional 40 feet of 24 inch by 38-inch oval storm drains with four storm drain manholes (Aronow, email message, December 12, 2022). Construction of the proposed improvements within the Canal School Road and Hills Ferry Road would occur within the 40-foot to 60-foot-wide public rights-of-way and on privately owned roads would occur within the roadbeds that are generally 20 feet wide. Construction of the proposed project would include trenching up to approximately 10 feet deep and up to 10 feet wide in pavement and dirt roads along the new sewer route. Construction and access easements would be required for the portion of the proposed project along the privately owned roads. Although the proposed route avoids placing the trunk line within actively farmed areas, the area of potential disturbance (access, trenching and temporary excavation spoil stockpiling) shown on the project plans, is about 30 feet wide and overlaps slightly with tilled acreage. Farming activities within this area may be temporarily suspended during construction. Proposed construction activities in public rights-of-way would include removal and replacement of asphalt, removing and resetting traffic signs, and replacing pavement markings and bicycle lane markings within public right-of-way. The existing 21-inch and 18-inch sewer trunk lines would be abandoned in place and there would be no increase in WWTRF treatment capacity. The total disturbance area would be approximately 2.37 acres (5,125 plus 40 feet linear feet = 5,165 linear feet x approximately 20-foot-wide disturbance area = 103,300/43,560 = 2.37 acres).
