Before you begin planting on that slope you should look at and consider what the condition of the slope area is like. Are there cracks that need to be filled or do you notice any potential erosion problems. If such problems exist then you need to fill the crack with top soil. You should also try raking and removing any debris and rocks. If there are rocks in the soil then it will make for a difficult planting process as it will be hard to dig. Remember that slopes like other planting beds have areas that get more sun or shade so researching the plant you wish to use and understanding it's sun/shade tolerance is always a great ides.

thanks for the article. there are certain plants which colonize very poor soils like you find on steep slopes. these are often nitrogen fixators like lupines, lotus species, and ceanothus species. these along w/ native bunchgrasses are excellent for establishing first on very steep slopes. some of the plants you mention in the 'california friendly' section are not friendly at ALL! in fact, almost all the species you mention are invasive and thereby destructive to the native species.
Pete,
I think that all non natives are technically invasive. Thanks for your comment.
thanks for the great article. Coir is also widely used to get the extra mechanical strength for slope stabilization.
Rama,
I am glad you are promoting natives and Ca friendly non-natives. Some non-natives are invasive and do great harm -- vinca, header, cotoneaster. Pls check your recommendations against the cal-ipc.org site.
