any exterior face of a building that maintains a uniform direction
NOTE: Individual façades, under BirdSafe standards, are further determined by type of glazing (i.e. transparent, tinted, mirrored, opaque) or special architectural treatment (alcove, atrium, etc.). If more than one type of glazing is installed at one face, each type of glazing is considered a separate façade.
Building Exemption: Any façade with existing bird deterrent markers that meets designated standards of size, spacing, contrast, and surface application will not require an assessment.
