Michel Design 7907 212th St. SW, Suite 102 Edmonds, WA 98026 Re: Soundview Lane, LLC. 3 Lot Short Plat, Edmonds, WA. Rob: This report is provided to address the requirement of the City of Edmonds for review of the Native Vegetation Plan for the Soundview Lane, LLC 3 Lot Short Plat prepared by Donna Breske. For preparation of this report, I have reviewed the Native Vegetation Plan as well as the City of Edmonds document Procedures for Obtaining Permitting and Approval for Tree Removal or Trimming with City of Edmonds Rights -of -Way. The Native Vegetation Plan shows the proposed removal of trees within the right-of-way and the proposed plantings to be installed as replacement for the removed trees. I did not conduct a site visit prior to preparation of this report. The purpose of this report is only to provide the results of my review of the tree replacement measures proposed to satisfy the City of Edmonds requirements. 1.0 Development Plan and Requirements The proposed development of the project site is to short plat it into three separate lots, retaining the existing house in one and developing two additional lots. Development of Soundview Lane will require the removal of 11 trees. Of these 11, 9 meet the minimum size requirement for replacement by the City of Edmonds. Following are the trees' sizes and their recommended replacement numbers: Tree Dbh # 36" 5 27" 5 24" 4 21" 4 13" 3 11" 2 11" 2 9" 2 9" 2 Based upon these numbers, the total recommended to be planted as replacement is 29 trees. The City of Edmonds doesn't specify species or minimum size for replacement trees. 2.0 Replacement Proposed and Recommended The Native Vegetation Plan proposes replacementlof the 9 within the right-of-way proposed to be removed that are required to be replaced.,by replanting with 36 trees of the following species, sizes and numbers: Species Size Number Douglas fir 5 gal. 5 Pacific dogwood 2 gal. 3 Paper birch 2 gal. 2 Shore pine 2 gal. 5 Vine maple 2 gal. 6 Western red cedar 2 gal. 15 In addition to these trees, the plan proposes to plant 44 shrubs and 77 ground cover plants. Of these replacement trees, vine maple and shore pine are smaller at maturity and will be part of the understory layer. Pacific dogwood and paper birch will be taller, but not as tall as Douglas fir and Western red cedar. As the Native Vegetation Plan shows, There are a number of trees that will be retained in both of the proposed restoration/tree replacement areas, 20 in all. Adding 36 trees to these areas will total 56 trees in these areas, both of which are long but very narrow. To accommodate the replacement trees and the existing trees, the spacing between many of the replacement trees is no greater than 10 feet. This spacing is not adequate for the larger trees as it will result in crowding and possibly require removal in the future. I recommend a minimum of 15 feet, preferably 20 feet, between the trunks of trees, particularly the Douglas firs and the Western red cedars. Therefore, I recommend reducing the number of Western red cedars planted to 5 for a total of 26 replacement trees. These trees should be located at the recommended spacing. It appears as though the western red cedars planted along the southern property line are intended to create a screen. I don't recommend planting these so close together. Spacing them will not create an immediate screen, but will provide one in the near future. 4.0 Use of This Report and Limitations This report is provided to Soundview Lane, LLC and Michel Design as a means of addressing the City of Edmonds' requirement for review of the proposed tree replacement specified in the Native Vegetation Plan. This report does not address the conditions of the retained trees. Therefore, Tony Shoffner and Shoffner Consulting cannot be held liable for damage resulting from the failure of any trees on the project site.
