Russian River County Sanitation District Sewer Main Repair Project - M31-4 to M36-14
Document Type
NOE - Notice of Exemption
Document Description
The project would replace approximately 60 linear feet of the existing sewer main collection pipe located between manholes M31-4 and M36-14 that has cracked and partially collapsed (Figure 1). The objective of the project is to replace the damaged section of pipe from approximately 9 feet upstream of M36-14 to approximately 69 feet upstream of M36-14. The area of disturbance includes approximately 9,000 square feet of land and would include approximately 80 linear feet of minor trenching within previously developed areas along the pipeline alignment. Previously developed areas consist of a gravel and dirt storage yard interspersed with ruderal non-native vegetation. Wastewater will be bypassed from a manhole upstream of the damaged section of pipe to a manhole downstream of the damaged section of pipe while the damaged section is being repaired. The bypass pipeline would be placed overland adjacent to the work zone. Project work will not result in an expansion of use.
