Walkway below grade

Is there a rule of thumb, or a code requirement when it comes to how much difference there should be between a residential sidewalk and the lawn alongside?

I am installing forms to extend an existing sidewalk over a sloped section of lawn. I have one section (6') of sidewalk that will be about 4-5" below grade on one side and 4-5" above grade on the other. I can fill the low side a bit, but I would have to remove a large area of lawn to get the high side level with the walk.

Anything over an inch or so on the uphill side should be either sloped at a less than 45 degree or faced. On the downhill side it should be less than an inch below finish grade and sloped away at 45 degree or less.

Would landscape timbers work to hold back the soil on the high side?
