Document Type
MND - Mitigated Negative Declaration
Present Land Use
Zoned Public Facility; General Plan Designation - Public Facility. Land uses in and around the project area include the Weaverville Historic Downtown (a historic district listed in the National Register of Historic Places [NR#71000209]), Trinity County right-of-way (ROW), Caltrans ROW including SR 299, Middle Weaver Creek, the Joss House State Historic Park, and the Jackson Memorial Museum/Trinity County Historical Park.
Document Description
The Trinity County Department of Transportation (County) proposes to improve public safety and increase hydraulic capacity by replacing the existing bridge (No. 05C-0036) on Lorenz Road over Middle Weaver Creek (project) and construct the necessary roadway approach improvements. The proposed new bridge would be a single-span concrete slab-type bridge, slightly wider and longer than the current bridge and aligned in the existing alignment. The new approach roadways on both sides of the new bridge would be slightly wider than the existing. The north abutment would have wingwalls extending to existing retaining structures, including a gabion wall at the northeast corner and a culvert wingwall?this culvert conveys Ten Cent Gulch under State Route (SR) 299?at the southeast corner. The replacement bridge design would be context sensitive due to it being located in a designated historic district and because of its adjacency to state and local historic parks. The new bridge would have architectural features that would complement the visual and historic character of the surrounding historical area.
