MDOT Eel River Road Culvert Replacement MPs 6.19 and 6.56 (Lake or Streambed Alteration Agreement No. 1600-2017-0057-R1)

The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2017-0057-R1, pursuant to Section 1602 of the Fish and Game Code to Mr. Kent Standley The project is limited to two encroachment. One encroachment will replace a culvert at MP 6.19 on Rocky Creek. A 57-inch arch culvert will replace a failing 48-inch circular culvert. It will be properly aligned, maintain the stream gradient, and pass 100-year flow events. A second encroachment, at an Unnamed Tributary at MP 6.56, will correct the placement of a 24-inch circular shotgun culvert, which is not aligned with the stream channel. A new 24-inch culvert will be placed in alignment with the stream channel, but cannot be placed at gradient because of the steepness and substrate of the slope. A 30-foot flume will deliver the outflow directly into the active channel of the Eel River to avoid erosion issues. The original culvert will remain in place as an emergency overflow culvert.
