This item consists of the final shaping, dressing and protection from erosion of shoulders, ditches and slopes in conformance with the cross- sections.
(A) In general, all shoulders, side slopes and ditches shall be protected from erosion by seeding and mulching as soon as possible after construction:
(1) Apply fertilizer as determined by soil tests or at the minimum rate of 1,000 pounds of 12-12-12 fertilizer (or its equivalent) per acre;
(2) The amount of pure live seed per acre shall be: 35 pounds of tall fescue or 20 pounds of bluegrass with 20 pounds of creeping red fescue, and a nurse crop of one bushel of oats, rye or wheat.
(3) Work in fertilizer two inches deep where possible, and seed grass one-quarter inch deep by firming or compacting the soil.
(4) Mulch areas with straw or suitable materials at a rate of one and one-half tons per acre. Site conditions may require mulch to be anchored.
(B) Earthen ditch side slopes shall be no steeper than 2:1.
(C) All ditch flow lines having grades in excess of 5% shall have a concrete paved side ditch or a hand laid stone riprap side ditch, as detailed in the proposal. In general, those special cases of erosion, not heretofore covered, shall be controlled by riprap and slopewall.
(D) All unpaved areas between the edge of the road pavement and the right-of-way line must support an adequate sod before the release of the three-year maintenance bond can be made.
