• • Planning Commission Minutes July 7, 1987 Page 2 considered quiet. Mr. Morton gave examples of noise levels are rustling leaves - 20 dBA, a car traveling on a street - 50 dBA, normal conversation - 50-60 dBA, an air conditioner - 60 dBA, a dishwasher - 75 dBA, a vacuum cleaner - 70 dBA. All these noise measurements were substantiated by Gary Doughty and I strongly recommend that we don't deviate from those standards. Ernst Staudt asked Mr. Morton what the area being surveyed looked like. Ray Morton stated that the area was wide open. Bill Strong had told the group that trees do not serve as a buffer against noise. Alders particularly do not protect against noise. Sharon Demuth, 3323 - 52nd Place S.W., Everett, WA then addressed the Planning Commission, stating that she is a biologist by vocation, but her topic this evening was drainage. I have lived in the area for approximately seven years. Ms. Demuth stated that most of the water slopes down and goes down into Powdermill Gulch in a very rapid manner. "There is essentially no drainage on the top of the hill. The water table is right at the surface level of the soil back there. Therefore, any water that hits runs off of the clay and sand there. The high water table is something that Mr. Bocek is going to have to deal with in developing the area. With construction going on, all of that water being generated will go quickly to the Gulch. The sides are unstable. If the present state of growth is disturbed, this will create a an aggravated erosion problem. Repairing the bridge over Edgewater canyon is something which has to be considered with any of this construction. If the trees and other foliage there are maintained that will be the biggest help." There was a discussion of tightlining and Mrs. Demuth stated that tightlining may or may not work depending on whether there are adequate measures taken to take huge a increase in the volume of water - flash flood. There are 105 acres in this parcel and 90% of the drainage goes directly into Powder Mill Gulch." There is pollution in the creek with petroleum/hydrocarbons presently there and with higher use, it will get worse. Don Berg, 3322 - 52nd Place S.W., Everett, WA told the Planning Commission that the committee he was on reviewed the zoning codes of nearby communities such as Redmond, Bellevue and Renton looking at their transition zones which is what we have here - residential to business park. They had considered noise, visual impact, overview. This is basically why we have come up with the idea of the berm and included a 150-foot buffer, the request for a 200-foot building setback. We think the height limitations are reasonable. We hope the City will give our proposal serious thought. Gary Doughty stated that after reviewing the written draft proposal and meeting with the neighborhood on July 1, the staff reviewed the proposal in house and feel it is a was very good proposal. The group had worked very hard to come up with this new solution very recently.
