Week 3 Update

The project continues to make progress towards the instillation of the new bridge. The initial concrete for the wing-walls has been poured this week following an inspection of the pilings. Evans Excavating has been working to regrade the approaches on either side of the abutments as well as finally remove the current crossing. Below are some photos of this week’s activity. Check back next week for more updates.

JS Morris worked to form around the rebar wing-wall structure prior to the concrete pouring.










The wing-wall structures on the creek’s right bank have been formed, poured and stripped to the next elevation. JS Morris has begun working on the left bank abutment and should have it to the next stage by the middle of next week.
Demolition of the old crossing started on Friday and will continue next week.












Prior to the removal of the old crossing we resurveyed the small pool for any sensitive species. We found three baby western pond turtles in the pool and relocated them downstream to San Antonio Creek.

Week 2 update

The Lion Creek project is well underway and progress is ahead of schedule. This week the pilings for both sides of the bridge were drilled and the concrete was poured. J. S. Morris Construction is working to finish welding the wire cages that will be the frame for the bridge abutments. These should be in place and poured with cement sometime next week. The removal of the current creek barrier is also planned to occur next week to make way for the new bridge. Check back next week for more photos.



Workers pouring concrete for the three piles which will support the abutments on each side of the creek.

Silt fencing marks the location of the piles which were recently poured. The new bridge will span the area between the two fences.


J. S. Morris Construction crew welding the joints on the rebar for the wingwalls.













Rebar wingwall structure is in place for one side of the bridge. The other side should be in place shortly as the construction crew prepares to have them filled by the end of the week.

Lion Creek Restoration Project Begins!!!


San Antonio Creek crossing was installed to allow the transport and access of heavy machinery to the Lion Creek Restoration site.












Dewatering of the pool under Lion
Creek Bridge coincided with fish and frog capture and relocation efforts. Two California Red-legged Frogs were found inside a culvert and were relocated downstream to the confluence of Lion Creek and San Antonio Creek. No Steelhead trout were observed at the site but hundreds of Stickleback and Chubs were caught and also relocated downstream to the confluence pool.







Excavation begins at the Lion Creek Bridge to prepare site for drilling and construction of new bridge abutments set to begin next week.




Check back next week for further updates on the projects progress.

The Lion Creek Steelhead Restoration Project involves the removal of a stream crossing which currently impairs steelhead migration and the replacement of the crossing with an 85 foot bridge. The project aims to improve steelhead access to approximately 9.5 miles of upstream habitat. Here are a few picture of the stream crossing prior to the project start.
