Note 2: The above are representative unit costs based on information collected from bid tabulation sheets from two years (1997 -1999) in the Eugene, Lebanon and Portland areas. These costs are representative of average conditions and assume that the CP projects are competitively bid. Unit costs include materials and installation. Actual construction cost will vary with site conditions and local factors at time of bidding. Unit cost for trees assumes bare root stock with temporary water for 2 -3 years. Note 3: With respect to Natural Resource Enhancement and Open Waterway Improvement Construction Costs (not included in this table), unit costs were revised (Nov. 2001) for clearing & grubbing, hydroseeding, trees & shrubs, and erosion control. See attached addendum. Reference: Table 5 (Unit Cost) x Table 6 (Quantities) = Table 7 (Unit Cost per CIP Type)
