4. Landscaping and Retainage of Existing Vegetation: A detailed landscaping plan shall be submitted to and approved by the Planning Commission as a part of the detailed site plan review process. This plan shall identify all buffer areas adjacent to neighboring properties, setback from adjacent public rights-of-way, internal landscaping between buildings, between buildings and parking areas, landscaping within parking areas, and their natural open spaces. Natural vegetation to be retained must be shown as well as specific new plantings by type, location and size (existing and potential). a. As part of the Master Site Plan, the developer shall provide a survey of all trees excluding alders on the site which have a trunk diameter of eight (8) inches or greater. Develpment on the site must retain the majority of those trees identified in the survey. b. Buffers Between Industrial Park/Business Park and Residential Areas: A naturally vegetated and landscaped buffer shall be provided sufficient to screen the view of the industrial park/business park development from any property designated for residential uses. A minimum of one hundred fifty (150) feet of landscaped and naturally vegetated buffer shall be provided adjacent to any property designated for residential uses. The south thirty (30) feet of the buffer shall include an earthen berm a minimum of ten (10) feet in height above the surrounding grade with a minimum slope of 3 to 1 (3:1) installed prior to occupancy of any buildings. Landscaping within the southernmost portion (30 feet) shall consist of a mix of predominantly evergreen plantings including living trees, shrubs, and ground cover. Evergreen trees shall be a minimum height of 5 to 6 feet at the time of planting. Plantings shall be chosen and spaced so as to grow together within three years sufficient to obscure sight through the barrier. The entire planting strip shall be landscaped; however, those plantings used to achieve the sight-obscuring screen shall cover at least five feet of the width of the strip and shall be located farthest from the property line. Existing vegetation, architectural barriers (including walls, planters, and fences) or grading (with a minimum slope of 3:1) may be incorporated into the landscape design. The remaining 120'-0" is to remain undisturbed. It is the objective of this condition to protect the adjoining residential property from any adverse impacts of industrial park development by: enhancing the aesthetic appearance of the buildings and activities, avoiding a reduction in residential privacy; providing sufficient separation between residential and the office and industrial park uses to minimize adverse air quality and noise impacts and preserving significant alder trees, evergreens and hardwood trees and to supplement existing vegetation with evergreen trees and shrubs of sufficient density and height so as to provide a year round sight obscuring buffer. c. Steep Sloped and Riparian Areas i. That area in Powder Mill Gulch within the entire one hundred five (105) acre site which has a topographic slope of greater than 25% and any areas within a minimum of fifty (50) feet of Powder Mill Creek shall be dedicated to the City of Everett for municipal purposes by statutory warranty deed free and clear of all liens, encumbrances, restrictions and reservations. This ravine area should be designated as an environmentally sensitive area by the City. -10-
