PROPOSAL SPECIFICATIONS Provide and plant trees, and provide and install irrigation system as follows: I/ We agree to furnish all trees, materials, labor and incidentals to perform the work below. • Mobilization, deliver and plant, B & B trees approximately 60" back of curb in the locations shown in the attached plan view document (Appendix). • A mandatory pre -construction meeting shall occur at the job with the City and the Contractor's on -site supervisor. • Each tree shall have no less than 1/2 cubic yard 'Plaisted's Growers Mix' incorporated into the parent soil immediately surrounding each tree, at a rate of 25% Plaisted's soil to 75% native or parent soil. • All trees shall be staked or paint -located in the ROW, approximately 40' O.C. by the contractor, and then verified/approved by a City representative. • Trees shall be thoroughly watered -in upon planting, and kept sufficiently moist by the Contractor until acceptance of the irrigation system by the City. • Trees shall be individually approved for planting on site by the City upon visual inspection —no park grade trees permitted, nor any defects in the trunk will be approved. • The root flare shall be properly located level with the top of the B-style curb, even if the ground level slopes down and away from back of curb. It is not anticipated that any soil generated from the tree planting excavations will be hauled away — rather, this sand may be evenly spread parallel to the curb line to level the ROW where the tree planting is to take place. • After the correct placement and planting depth is approved by the city representative, a 4' diameter circle of 'mink mulch' wood chips shall be placed around each tree, 3" to 4" in depth. • All trees shall be warranted for a period of 18 months following installation and acceptance by the City. 2 I Page
