         b.   Exception
            The PDSD Director may approve an IID Plan providing less than 50% shade where compliance is not feasible due to a location and/or orientation and the applicant has made a reasonable attempt to comply with this standard.
   B.    Transition
      The purpose of the Transition is to mitigate excessive visual, noise, odor, vibration intrusion, and other similar public health and safety concerns that may be created by the proposed .
      1.   Applicability

         a.   "Affected residential property" refers to an existing detached single-family or duplex dwelling that is to a developing site;
         b.   "High density residential" refers to residential that is neither existing single-family detached nor attached dwellings;
         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.
      2.   Mitigation of Taller
         Compliance with the following is required where the developing site has taller buildings than affected residential properties:
         a.   Within the GIIS and DCS, the maximum building height is 25 feet within 30 feet of the property line to an affected residential property. Proposed buildings may be developed to the maximum height permitted by the underlying or as permitted by the IID Subdistrict, whichever is applicable, when the building is 30 feet or more from the property line to an affected residential property;
         b.    Bulk Reduction
            If a façade faces a property line to a single-family detached or duplex residential property, the PDSD Director may require bulk reduction. The shall make a finding and recommendation, after consulting with the DRC and/or Historic Commission if applicable, that the proposed design provides an effective way of breaking up the mass so the mass of the façade is less imposing.
         c.   Windows at or above the second story of a shall be located or treated to reduce views into affected residential property's and yard areas;
         d.   Balconies shall be oriented away from affected residential property or use a screening device to reduce views in to the rear or side yards of the affected residential property.
         e.   The developing site's shall be oriented so as to reduce views onto an affected residential property; and
         f.   Buffers and/or screening consistent with the purpose of this section shall be provided between a developing site and affected residential properties and shall include features such as, but not limited to, landscaping, walls, and architecturally decorative features.
      3.   Mitigation of Service Areas
         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. An alternative treatment may be used, such as using architectural or landscaping treatments that effectively reduce nuisance impacts from parking facilities and other areas. Where there is a finding that the vegetative screen will be opaque, the requirement of a masonry wall may be waived by the PDSD Director.
