Calistoga Riverside Ponds Relocation Project
Document Type
ADM - Addendum
Document Description
The project involves relocation of four existing riverside ponds and associated water conveyance and treatment utilities at the Dunaweal Wastewater Treatment Plant (WWTP); realigning river channels away from WWTP infrastructure, restoring a vegetated riparian buffer, and stabilizing channel banks between the riverside ponds and headworks structure and the adjacent active river channels to protect the facilities from subsequent erosion. This addendum to the adopted IS/MND addresses the addition of an on-site temporary construction staging area, use of an existing temporary access route, and construction of a permanent river level sensor.
