4. Storage of junk motor vehicles on any property outside of a legally constructed building (minimum of three sides and a roof) is prohibited, except where the storage of up to six junk motor vehicles meets one of the following two conditions: >a.  Any junk motor vehicle(s) stored outdoors must be completely screened by a sight-obscuring fence or natural vegetation to the satisfaction of the director (a covering such as a tarp over the vehicle(s) will not constitute an acceptable visual barrier). For the purposes of this section, “screened” means not visible from any portion or elevation of any neighboring or adjacent public or private property, easement or right-of-way; or b.  Any junk motor vehicle(s) stored outdoors must be stored more than two hundred fifty feet away from all property lines. >c.  Environmental Mitigation Agreement. The owner of any such junk motor vehicle(s) must successfully enter into an environmental mitigation agreement with the department of community development (the “department”) regarding the property where such vehicle(s) will be located or stored. i.  An environmental mitigation agreement between a property owner and the department is required before the outdoor storage of up to six screened junk motor vehicles will be approved. A property owner may enter into such agreement with the department for a one-time fee of $10.00 per vehicle, the proceeds of which shall be used to assist with clean-up costs associated with the administration of Chapter 9.56. ii.  In order to mitigate any potential environmental impact from the storage of these junk motor vehicles, the property owner must agree to institute one of the following two preventative measures: (a)  Each junk motor vehicle must be drained of all oil and other fluids including, but not limited to, engine crankcase oil, transmission fluid, brake fluid and radiator coolant or antifreeze prior to placing the vehicle on site; or (b)  Drip pans or pads must be placed and maintained underneath the radiator, engine block, transmission and differentials of each junk motor vehicle to collect residual fluids. >(c)  Either preventative measure shall require that the owner of such vehicle(s) clean up and properly dispose of any visible contamination resulting from the storage of junk motor vehicles. The agreement will require the property owner to select one of the two preventative measures and to allow for an initial inspection of the property by the department to assure that the preventative measure has been implemented to the satisfaction of the department. By entering into the agreement, the property owner further agrees to allow the department entry onto the property on an annual basis for reinspection to assure compliance with the approved agreement. If a property is found to be in compliance with the terms of the agreement for two consecutive inspections, the department may waive the annual inspection requirement. A property owner found to be in violation of the agreement may be issued a civil infraction pursuant to this section and could later be deemed a nuisance in accordance with Chapter 9.56.

5. In urban zones, all new residential subdivisions, single-family or multifamily developments are required to provide an urban level of sanitary sewer service for all proposed dwelling units unless exemptions identified in Section 17.460.020 allow for the implementation of a dry sewer.
