NOTES1. STREET TREES SHALL BE PROVIDED AS FOLLOWS (PER KCRS 5.03 AND KCC 21A.16.050):

- TREES SHALL BE PLANTED AT A RATE OF ONE TREE FOR EVERY 40 FEET OF FRONTAGEALONG ALL ROADS. SPACING MAY BE MODIFIED TO ACCOMMODATE SIGHT DISTANCEREQUIREMENTS FOR DRIVEWAYS AND INTERSECTIONS.

- TREES SHALL BE LOCATED WITHIN THE STREET RIGHT-OF-WAY AND PLANTED INACCORDANCE WITH DRAWING NO. 5-009 OF THE KING COUNTY ROAD STANDARDS, UNLESSKING COUNTY DEPARTMENT OF TRANSPORTATION DETERMINES THAT TREES SHOULD NOTBE LOCATED IN THE STREET RIGHT-OF-WAY.

- IF KING COUNTY DETERMINES THAT THE REQUIRED STREET TREES SHOULD NOT BELOCATED WITHIN THE RIGHT-OF-WAY, THEY SHALL BE LOCATED NO MORE THAN 20 FEETFROM THE STREET RIGHT-OF-WAY LINE.

- THE TREES SHALL BE OWNED AND MAINTAINED BY THE ABUTTING LOT OWNERS OR THEHOMEOWNERS ASSOCIATION OR OTHER WORKABLE ORGANIZATION UNLESS THE COUNTYHAS ADOPTED A MAINTENANCE PROGRAM. OWNERSHIP AND MAINTENANCE SHALL BENOTED ON THE FACE OF THE FINAL RECORDED PLAT.

- THE SPECIES OF TREES SHALL BE APPROVED BY DPER IF LOCATED WITHIN THERIGHT-OF-WAY, AND SHALL NOT INCLUDE POPLAR, COTTONWOOD, SOFT MAPLES, GUM ANYFRUIT BEARING TREES, OR ANY OTHER TREE OR SHRUB WHOSE ROOTS ARE LIKELY TOOBSTRUCT SANITARY OR STORM SEWERS, OR THAT IS NOT COMPATIBLE WITH OVERHEADUTILITY LINES (SEE LIST OF ACCEPTABLE TREES ABOVE).

- THE STREET TREE PLAN SHALL BE REVIEWED AND APPROVED BY THE DPER REVIEWENGINEER IN COORDINATION WITH THE DPER FORESTER FOR SIGNIFICANT TREERETENTION.

- THE STREET TREES MUST BE INSTALLED AND INSPECTED OR A PERFORMANCE BONDPOSTED PRIOR TO RECORDING OF THE PLAT. IF A PERFORMANCE BOND IS POSTED, THESTREET TREES MUST BE INSTALLED AND INSPECTED WITHIN ONE YEAR OF RECORDING OFTHE PLAT. AT THE TIME OF INSPECTION, IF THE TREES ARE FOUND TO BE INSTALLED PERTHE APPROVED PLAN, A MAINTENANCE BOND MUST BE SUBMITTED OR THE PERFORMANCEBOND REPLACED WITH A MAINTENANCE BOND, AND HELD FOR ONE YEAR.
