I live ina coldusac in unnicorporated Bothell. My neighbor is running a septic construction business from his back yard. He has an enormous dump truck, 2 large flatbed trailers, an industrial back hoe, 2 f350 work trucks, a bobcat, and 1 smaller back hoe. The vehicles are in and out of the neighborhood several times a day posing eminent danger to property and children. He runs the diesel dump truck for about an hou each morning flooding my basement w/exhaust. Is it legal for him to run such a business from his house and store the equipent both in his yard and any available space in the surrounding neighborhood?
