         c.   Examples of applicable transitional areas include a nonresidential developing site to existing single-family detached or attached dwellings within a subdivision, or a developing high density residential site to existing single-family detached or attached dwellings within a subdivision; and,
         d.   For within the DCS, the Transition apply only to those to affected residential properties outside the DCS boundaries.

         Potential nuisance or noisy areas shall be oriented away from affected residential property, such as by placing service areas for loading and garbage disposal between the developing site's , behind opaque barriers, or by using architectural or landscaping treatments that effectively reduce nuisance impacts from service areas. The service area shall be mitigated to reduce the noise and view of the service features, reduce the emission of offensive odors to owners or occupants of properties or create a nuisance or hazard beyond the property lines of the , and prevent vibrations that are discernible beyond the property lines of the .
      4.   Mitigation of Parking Facilities and Other Areas
         Where the site has parking areas or an area with noise and outdoor lighting features, the areas shall be screened from affected residential property by a combination of a wall or opaque non-chain link fence with a vegetative hedge or a row of trees that shall be dense enough to screen views onto the site.
