    (a) Costs to design, construct, repair, or modify a grade stabilization structure.
    (b) Costs for leveling and filling needed to install the structure.
    (c) Costs to establish permanent vegetative cover, or to provide temporary cover until permanent cover is established. This may include costs for mulch, fertilizer, seed, and other necessary materials.
    (d) Costs for fencing to protect the structure.
