Viewpoint #3
The sky plane obstruction for the 888 Boylston site under existing conditions
occupies approximately 5.8 percent as viewed from the centerline of Boylston Street.
The establishment of a 155-foot building at this location will increase the building’s
massing and appearance from the centerline of Boylston Street by an additional 21.9
percent of the sky plane resulting in a total obstruction of 27.7 percent as calculated
by the BRADA model. Figure 5-33 summarizes the 155-feet zoning height scenario
for 888 Boylston from Viewpoint #3.
Viewpoint #4
The sky plane obstruction for the 888 Boylston site as viewed from the Fairfield plaza
study point is currently occupied by 58.5 percent of the sky plane. The establishment
of a 155-foot building at this location will have no effect on the percentage of sky
plane obstructed resulting in no change to the total obstruction of 58.5 percent as
calculated by the BRADA model for existing conditions. Figure 5-33 summarizes the
155-feet zoning height scenario daylight conditions for 888 Boylston from Viewpoint
#4.
Viewpoint #3
The sky plane obstruction for the 888 Boylston site under existing conditions
occupies approximately 5.8 percent as viewed from the centerline of Boylston Street.
The establishment of the proposed 17-story building at this location will increase the
building’s massing and appearance from the centerline of Boylston Street by an
additional 30.3 percent of the sky plane resulting in a total obstruction of 36.1 percent
as calculated by the BRADA model. Figure 5-34 summarizes the proposed daylight
conditions for 888 Boylston from Viewpoint #3.
Viewpoint #4
The sky plane obstruction for the 888 Boylston site as viewed from the Fairfield plaza
study point is currently occupied by 58.5 percent of the sky plane. The establishment
of the proposed 17-story building at this location will have no effect on the
percentage of sky plane obstructed resulting in no change to the total obstruction of
58.5 percent as calculated by the BRADA model for existing conditions. Figure 5-34
summarizes the proposed daylight conditions for 888 Boylston from Viewpoint #4.
The proposed developments will alter the view of the sky plane from the adjacent
streets and sidewalks. The effect from Exeter Residences cannot be avoided because
