A. Generally, where trees are closely spaced or provide dense shade, prune to remove between 20 to 25 percent of the foliage from the outer crown to allow more light penetration.

B. Tree pruning consists of the total removal of dead or living branches as may threaten the future health, strength and attractiveness of trees. Specifically, prune trees in such a manner as to:

1. Prevent branch and foliage interference with requirements of safe public passage. Keep over street clearance to a minimum of 16 feet above the paved surface of the street, 15 above the curb, and 8 feet above the surface of a public sidewalk or pedestrian way. Exceptions are allowed for young trees, which would be irreparable damaged by such pruning action. 2. Remove dead and dying branches and branch stubs that are 1/2 inch diameter or larger. 3. Remove broken or loose branches.

4. Remove live branches which interfere with the tree’s structural strength, and healthful development, which include the following:

a. Branches that rub and abrade a more important branch. b. Branches of weak structure that are not important to the framework of the tree. c. Branches, that if allowed to grow, would wedge apart the junction of more important branches. d. Branches forming multiple leaders in a single leader type tree. e. Branches near the end of a limb, that will produce more weight or offer more resistance to wind than the limbs are likely to support. f. Selective removal of undesirable sucker and sprout growth paying specific attention not to nick or damage the sprout “burl.” g. Selective removal of one or more developing leaders where multiple branch growth exists near the end of broken or stubbed limbs. h. Selective removal of limbs obstructing buildings or other structures or traffic signs. Generally, limbs closer than five (5) feet to a building or other structure should be removed unless doing so would severely damage a tree. i. Removal of branches, which project too far outward beyond an otherwise symmetrical form.

C. Cut back branches completely to reduce weight where excessive overburden appears likely to result in breakage of supporting limbs.

Portland Parks & Recreation 1120 S.W. 5th Ave., Suite 1302 Portland, Oregon 97204 Project Name Tree Pruning: 32 9013 MASTER – July 31, 2015 Page 4

Requirements of the Work As-Built and Record Drawings

1. The Construction Contractor shall mark up all changes from the Bid Set or Construction Set, whichever set was issued by the PPR (Portland Parks & Recreation) Project Manager as the drawing set to construct from. The Contractor shall use red to indicate any element that was removed from the drawing, green to indicate any elements that were added to the drawing, and any element requiring changes or editing in blue. No White-Out or black ink shall be used. Contractor shall include all ASIs (Architect’s Supplemental Instructions), FCDs (Field Change Directives), approved substitutions, and all other changes to the drawings during the course of the project, by attaching the most current version of changes issued to the drawing. Contractor who is documenting as-built information shall mark in the lower right corner of each drawing with the words “As Built”, the date, signature, and company name who provided the as-built information. (Further instructions to contractor provided in PPR Division One specifications.)

2. Once the construction contractor has submitted their complete set of as-builts for review, the PPR Project Manager (PM) and/or Construction Manager (CM) will distribute them to the design consultants and PPR staff as necessary for review for completeness and accuracy. Design consultants and PPR staff shall submit to the PPR PM or CM their comments regarding anything not indicated correctly or that they are aware is missing from the contractor’s mark ups.

3. The PPR PM or CM will return the review comments and as-builts to the construction contractor for correction, as necessary. Once an acceptable set of As-Builts has been received by PPR from the contractor, the design consultant shall color scan each sheet that has color mark ups and black & white scan each sheet with no color mark ups, resulting in one .pdf per sheet for the entire set. This scan will serve as the As-Builts for the project records showing what changed during the course of the construction project.

4. The design consultants shall draft the as-built changes into CAD from the contractor mark ups and any other changes the design team is aware of that may not have been reflected by the contractor, including all ASIs, FDCs, approved substitutions, etc. All bubbles and deltas should come off the Record Drawings and in the titleblocks, and the drawings should only show the final condition, not what changed. Nothing should be crossed out to show the difference between the bid or construction set and what was built. Only show the final condition. Also

include all measurements the contractor has provided to indicate the actual location of underground improvements from a known point of reference. If the underground improvements were built within reasonable proximity, dimensions will suffice to show the actual location is over a few feet. If underground improvements were installed in significantly different locations, redraw the elements to the correct location on the drawings, and also include the dimensions.

5. Label in an appropriate location in the title block “Record Drawings” and the date. Also label “Record Drawings” in larger letters outside the title block in the lower right corner of each sheet.

6. Design consultant shall submit draft Record Drawings set(s) (hard copy or electronic in .pdf format, as directed by PPR PM) to PPR PM for review, along with the contractor As-Built mark-up set(s). Make corrections if necessary and resubmit for PPR PM approval.

7. Each drawing sheet shall be individual document files in both .pdf and CAD formats. See CAD Delivery document for specifications.

8. Final products are to be delivered via e-mail/FTP/CD-Rom or DVD.
