2. Setbacks, Principal and Accessory Structures/Uses. The minimum setback shall be measured from the closest point on the property line or the edge of the road travel way to the structure/use, whichever is closer. The minimum required setbacks for permitted uses are:
   1. For those HI Zoning Districts which abut HI, LI, or PD Zoning Districts, the setbacks shall be a minimum of 5 feet, except that the structure/use shall maintain a setback of 20 feet from any road travel way and any other setbacks required by building codes.

4. Distance Between Structures. Except as otherwise provided in these Zoning Regulations, the minimum distance between structures shall be 15 feet, 10 feet for multiple-household structures. Nothing herein shall prevent the permanent attachment of principal structures.
5. Screening. Whenever a non-residential use abuts a residential Zoning District or is separated therefrom by an alley, the developed area of the non-residential site shall be screened with a 6-foot-high solid screen (see Article 2.03 for definition). The County Zoning Inspector may defer the screening if the abutting residentially zoned property is not yet developed with a residential use.

No use shall be permitted which creates electrical disturbances that unreasonably affect the operation of any equipment beyond the boundaries of the site.

No noise or vibration (other than normal vehicular traffic) shall be permitted which is discernible on neighboring residential sites to the unaided human senses for 3-minutes or more duration in any one-hour of the day between the hours of 7:00 a.m. to 7:00 p.m. or of 30-seconds or more duration in any one-hour during the hours of 7:00 p.m. and 7:00 a.m.

9. Other Nuisances or Emissions Beyond the Site Boundaries. No emission shall be permitted which can damage health, animals or vegetation, or other forms of property, or which can cause any nuisance or hazard.

Accessory uses are permitted in the HI Zoning District, provided they are customarily incidental to an established permitted principal use. Accessory structures may exceed the size of the principal structure, provided that all other site development standards are met.

1. One dwelling or recreational vehicle for the family or employees of the owner/operator or caretaker of the site of principal use.
2. Recreational Vehicles (RVs) are allowed as follows:
