1 HAZARDOUS TREE AND LIMB REMOVAL DRC Emergency Services has extensive experience in the removal of downed trees, felling damaged trees and clearing of vegetative debris. In all aspects of this work DRC ensures its employees work in a safe and efficient manner,utilizing the most appropriate equipment and best work practices. An eligibility determination shall be made by the jurisdiction or its representative using the following criteria: * A tree is considered "hazardous" if its condition was caused by the disaster; if it is an immediate threat to lives, public health and safety,or improved property;and if it is six inches in diameter or greater,when measured two feet from the ground;and one or more of the following criteria are met: • It has more than 50 percent of the crown damaged or destroyed. • It has a split trunk or broken branches that expose the heartwood. • It has fallen or been uprooted within a public use area. • It is leaning at an angle greater than 30 degrees. Trees determined by the jurisdiction to be hazardous and that have less than 50 percent of the root-ball exposed should be cut flush at the ground level. The cut portion of the tree will be included with regular vegetative debris. The eligible scope-of-work for a hazardous tree may include removing the leaning portion and cutting the stump to ground level. Right of way(ROW)removal of dangerous hanging limbs(hangers) Criteria for the removal of hangers will be determined by the jurisdiction using the following criteria: Limbs must be: • Greater than 2"in diameter • Still hanging in a tree and threatening a public-use area(trails,sidewalks,golf cart paths) • Located on improved public property All hazardous limbs in a tree should be cut at the same time, not in passes for particular sizes. DRC specialized equipment,such as Giraffes or circular telescoping trimming apparatus that is capable of making hundreds of cuts in a ten hour day. Downed trees will be removed utilizing a combination of ground crews and equipment, the exact mix of which will depend on the disposition of the debris material. For example, trees on roadways will first be moved to the right-of- way (ROW) with heavy equipment (e.g. front end loader, excavator, skid-steer loader) before being cut by a ground crew into portions which can be placed in self-loading knuckle-boom trucks. Eligible trees off the ROW will be pulled towards the roadway with heavy equipment before being reduced to an appropriate size and placed in self-loading trucks. Standing or leaning damaged trees will be felled to the ground before reduction and loading,as described above.The felling of trees will be by certified fallers with chainsaws or with tree felling equipment(e.g. Hydro-Ax) and on some occasion Feller-bunchers,depending on location,access and size. Vegetative debris on the ground will be handled as described for downed trees, with equipment used to pile the debris on the ROW where it can be accessed by self-loading trucks for removal and disposal. DRC places safety above all else in all its work and all employees on site will be trained for their specific tasks. Appropriate personal protective and safety equipment(PPSE) will be worn at all times (e.g. head, hearing and hand protection) on the job site. Chainsaw operators shall be required to wear approved leg(chaps) and foot protection in addition to the mandatory PPSE. Only designated,qualified personnel shall operate machinery and mechanized equipment. Machinery or equipment shall not be operated in a manner that will endanger persons or property,nor shall the safe operating speeds or loads be exceeded. •a DRC Emergency Services,LLC 58 O E»�E.,<Y sEA �E: RFP No.18-04-02 -- --Sing Back.
