We will be periodically posting and sending out "Tips" to help you select and apply BMPs in the most effective manner. These tips are based on my experience - Iv'e actually built them, monitored the applications, and then given a lot of thought on how to make them better. This is my opinion only.

We tackled the fill slope portion of the trail yesterday. Kind of complex because we had to wrap and reinforce. Innovative stuff but only alternative given the constraints and "sapping/subsurface" conditions. All in all, a pretty good day for 6 people.
Here are some pics!
This trail above Hwy 44 in Redding will take walkers to awesome vistas.
However it "cuts" through some ancient river aggregate, semi-consolidated , with cobbles, gravel, sand, clay and a really nasty shrink-swell clay from old lake or?? When it rained big a few weeks back the water oozed out of the slope. What can be the fix? A retaining wall with drainage? soil nailed wall? Something very engineered and expensive?
We are going with compost (will encourage deep rooted native bunch grass (nasella pulchra) that will ultimately anchor and reinforce the soils) but the compost and soils need to be reinforced with ENKA Mat first. We decided to use anchors (long pins 12-18" long) that will "push back" at the forces "weeping out". We added mycorrhizae to provide the symbiosis needed for the grass. We also decided upon a 50/50 mix of compost and sandy loam soil import to 'fill in' eroded areas.
