The reports will include historic contexts, a summary of field methods and results, significance evaluations of historic period resources under appropriate criteria. Shade/Shadow Analysis Chambers Group will conduct shade and shadow analysis. Shading refers to the effect of shadows cast upon adjacent areas by proposed structures. Shadow impacts are dependent upon several factors, including sensitivity of adjacent land uses, duration, time of day, season, extent of building shadowed, preexisting conditions and type of shadow. Shade and shadow impacts could be considered substantial if a development creates a significant increase of shade or shadow on sensitive outdoor uses, defined as schools, hospitals, senior housing, or other residential amenity spaces. Shade and shadow impacts during the hours of 9:00 AM, 12:00 PM and 3:00 PM Pacific Standard Time at the winter solstice will be measured.
