The trees are located along Longacres Drive and are a potential hazard to pedestrians, vehicles and the electrical power of the substation for the regional wastewater facility. The applicant has provided documentation from a certified arborist that the trees were unintentionally propagated, and no critical areas or habitat would be impacted by their removal. PROJECT LOCATION: 1200 Monster Way SW (Along Longacres Drive) 242304-9006 PARCEL ID NUMBER: GENERAL REVIEW. CRITERIA (4-4-130H3): a. The land clearing and tree cutting will not create or significantly contribute to landslides, accelerated soil creep, settlement and subsidence or hazards associate with strong ground motion and soil liquefaction. The proposal does not appear to contribute significantly to any of the above-mentioned hazards. b. The land clearing and tree cutting will not create or significantly contribute to flooding, erosion, or increased turbidity, siltation or other form of pollution in a watercourse. The trees that will be removed are not in close proximity to any watercourse or wetland, and therefore, their removal will not contribute to any flooding, erosion or increased turbidity. c. Land clearing and tree cutting will be conducted to maintain or provide visual screening and buffering between land uses of differing intensity, consistent with applicable landscaping and setback provisions of the Renton Municipal Code. The 21 black cottonwood trees provide a screening function along Longacres Drive. Because they act as a visual buffer along the roadway, staff recommends as a condition of approval the replanting of trees that are more appropriate for this location. RVMP Template.doc d. Land clearing and tree cutting shall be conducted so as to expose the smallest practical area of soil to erosion for the least possible time, consistent with an approved build-out schedule and including any necessary erosion control measures. Staff recommends that as a condition of approval, best management practices for tree removal be employed so as to meet this criterion. e. Land clearing and tree cutting shall be consistent with subsection D2 of this section, Restrictions on Critical Areas -General, and RMC 4-3-050, Critical Areas Regulations. The proposal does not impact any critical areas. CONDITIONS OF APPROVAL: I. The applicant shall submit a replanting plan to the Development Services project manager for review and approval prior to removing and replacing the cottonwoods. 2. The applicant shall employee best management practices for erosion control during the tree removal process. This Routine Vegetation Management Permit is hereby approved, subject to the aforementioned conditions.

The trees are located in the City of Renton but are currently managed by the county wastewater facility. An arborist has written an assessment and has concluded that all 21 trees that align Longacres Drive should be removed. The assesment states that they are a potential hazard to pedestrians, vehicles and to the electrical power of the substation for the regional wastewater facility. Unofficially, it has also been mentioned by another arborist that the tree roots could potentially tear out the sidewalk if a tree were were to fall. The trees in question are a row of black cottonwood trees that unintentionally propagated along Longacres Drive. We believe that there are no critical areas that will be impacted by the tree removal activity. The downed, damaged and threatening trees will be removed at county expense pending review of this document by the City of Renton. This information has been provided to the city as a courtesy to notify our intent in this matter. The arborist's evaluation is attached. Sincerely, Mike Fischer, Plant Operations Manager King County South Treatment Plant CREA TING RESOURCES FROM WASTEWATER ·, • TREE ASSESSMENT REPORT: Renton Treatment Plant KC Waste Water Division Troy Deady KCDNRPPSII Certified Arborist Introduction On January 29, 2007 I received the following request from Donna Krell, intern with the KC Waste Water Division. There are 2 trees down and one leaning on the southern edge of the Renton Treatment Plant. The trees are actually on each side of Longacres Way which Js open to the public to drive on. There is concern that more trees could fall so we would like to get this started as soon as possible. We need to have a certified arborist assess the situation and make recommendations in a report. After that we will need to go to the City of Renton for pennitting. We were hoping to be able to do as much of this in-house if at all possible. If not, is it possible to get recommendations on another certified arborist and additionally are there any recommendations on who can cut/trim the trees? On February 9, 2007 I met atthe site with Mark Sakagami, senior gardener for the KC Waste Water Division and inspected 21 Black Cottonwoods at the site. The trees are located between Grady Way on the westbound side of Longacres Drive to the comer of Henry M. Jackson Place. ', SUMMARY A tree risk assessment was performed on 19 Black Cottonwoods on Longacres Drive SW. The trees are located south of a large electrical Power Station and the King County Waste Water Treatment plant in Renton. This assessment was requested because two of the larger trees from the group fell during the Dec 15, 2006 windstorm. A third tree is now leaning on another which has created a hazard. These trees range from 45' to 100' tall. My observations on February 9, 2007 were based on visual tree assessments. No invasive tests such as drilling or coring have been conducted. All observations were made from the ground. My findings that support the removal of these 19 trees are as follows: 1. These trees are in close proximity to the Power Station and Treatment Plant. 2. These trees were not planted intentionally where they are but started naturally. By design they will hecome more hazardous as they grow and will become more difficult to remove. 3. They grow in a row 12' from a pedestrian sidewalk and 18' from a moderately used road. 4. They are growing on a 30 to 45 degree slope toward the Power Station. 5. During the December 15th windstorm 2 of the trees on the west end fell down towards the north. This is towards the Power station and Treatment plant. The next tree in line fell and is now leaning to the east onto other trees creating a hazard. 6, Four of the smaller cottonwoods are leaning naturally towards the Power Station at approximately 5-15 degrees. 7. Black Cottonwoods have been known to drop large scaffold branches during all times of the year. Many such branches overhang the sidewalk and road. 8. There is a second stand of Cottonwoods located in a planting site on the opposite side of the road near I 405. Since our normal winds come from the south the removal of the first stand should not increase vulnerability of the second stand. 9. Smaller more manageable ornamental trees have been planted to the north in the recent past. These would be more suitable in this location. lREE ,..ssessMENl KC W•""" Wallet Tl eatn>efll Sile 21 Boe\< co11:onwoocl Trees 2 on the g<ouod 1 ieanin9 16 standl'9 ,ro~ Oead~ 2115/07 Pawer Sta\ron poWerlines 911}(50 1 0 1"J"Y..5rJ 0 1rJ'Y..45' 0 ,TY..100 0 26")(90' 0 21•)(90' 0 2G")(100 0 s R 0 26")(100 0 D ,.. 2rJ'}(I00 0 E D 25")\100' 0 ,N ,..
