§ 90.156. Revegetation: seedbed preparation.

(a)  The soil surface shall be prepared by disking or harrowing. If soil conditions or steep slopes prohibit the practices, the soil surface shall be scarified by any mechanical method which will loosen the surface material. Scarification will not be required if seeding is done immediately following final grading when the soil is still loose.
(b)  Disking or harrowing shall be accomplished following or along the contours of all slopes.
(c)  Topsoil shall be disked or harrowed to a depth of at least 3 inches prior to seeding.
