You might get away with soil adding in 1" steps, allowing the sod beneath to
take hold each step. Do use a row of sod perpendicular to the elevation to
help retain the soil every 4 feet or so. Or, 1" gravel as an alternative.
The last 1" of soil don't add any retention material. However, this is
prohibitively expensive on the hired labor end. You'd probably have to do
it yourself.
