Oregon DOT hydroseeding & erosion-control specs.
ODOT defers seed species and rates to the project Special Provisions and Plans. Erosion & sediment control is governed by Section 00280 and seeding methods/materials by Section 01030 — there is no fixed statewide roadside mix.
Other state specs
Section 00280 — Erosion & Sediment Control; Section 01030 — Seeding (2024 Standard Specifications)
Deferred-mix state
Seed mix policy
Species and rates are deferred to the project Special Provisions / Plans; Section 01030 governs seeding methods and materials, not a fixed statewide mix.
Mulch & tackifier rules
Paper/cellulose fiber mulch is allowed for hydroseeding under the base spec; polyacrylate (cationic) tackifiers are not accepted — approved tackifiers must be plant-derived / guar, or listed on the ODOT QPL.
Spec-numbering note
Erosion & sediment control = Section 00280; seeding = Section 01030. Section 01040 is "Planting" (landscape plant material), NOT erosion control or seeding — do not cite 01040 for hydroseeding.
