Document Description
The California Department of Transportation (Caltrans) proposes to perform continued routine maintenance in Lake County on State Route (SR) 20 Post Mile (PM) 39.37, also known as Grizzly Creek weir. Maintenance of this weir was previously covered under expired Lake and Streambed Alteration Agreements 1600-2007-0247-R2 and 1600-2016-0036-R2. Caltrans is now pursuing a 12-year Routine Maintenance Agreement from CDFW to perform this work annually or biennially. The scope of work remains consistent with previous agreements; Caltrans will remove light vegetation and up to 2000 cubic yards of sediment from the rock lined weir retention area. This work takes 1-3 weeks depending on the level of accumulated sediment. The purpose of this maintenance is to remove accumulated sediment from the retention area and restore proper function of the weir. The project is needed to maintain a safe traveled way for SR 20 during flood events, extend the service life of SR 20, and reduce high sediment loading in Grizzly Creek downstream. All work occurs within Caltrans right of way.
