PLANTING NOTES:

1. Verify limits of disturbance in field prior to commencement of planting activities. If construction disturbance in the field exceed the areas shown in plans, notify owner's representative to rectify adjustments.

2. Coordinate planting activities with all mobilization and construction operation, flagging and traffic control specifications.

3. Verify location of existing overhead utilities, sight lines, subsurface utilities, and other conflicts prior to commencement of planting activities. Locate and label underground utility lines prior to digging.

Adjust planting layout to eliminate conflicts.

4. Verify annual seasonal stream flow conditions prior to commencement of planting activities. All coniferous tree plantings are to be located above Ordinary High Water Line.

5. Disturbance and impacts to existing native vegetation shall be minimized to the greatest extent practicable. Refer to Hydraulics Plans for placement of large woody debris.

6. Specified willow cuttings to be coordinated with and installed after placement of soiled riprap material. Verify elevations prior to installation.

See Plant Cutting Installation in Riprap Detail.

7. Planting areas shall be prepared in accordance with the ODOT 2024 Oregon Standard Specifications for Construction and the project specific Special Provisions.

8. Contractor shall verify the availability of sufficient existing planting soil on site prior to construction. If imported topsoil is needed, submit topsoil type, source, and quantity for approval before commencement of construction.

9. Plant trees according to the Tree Planting detail. This work does not include wire tree ties.

10. Provide browse protection for all container plants. See Tubeling Protection detail.

11. Mulch and tackifier shall be utilized during all seeding applications.

12. Plantings shall be irrigated manually or by other approved method, as necessary, to ensure plant establishment.
