Proposed Program
On March 21 and September 21, the proposed Exeter Residences is expected to result
in a small increase in shadows cast towards Boylston Street at 9 AM filling in a small
gap in existing shadows opposite the Mandarin Hotel. The noon shadows are not
expected to increase beyond the sliver described above for the 155 foot building.
Any new shadows caused by the increased height will not reach the sidewalk or
other pedestrian areas. Similarly, at 3 PM and 6 PM the additional height of the
proposed Exeter Residences building will not increase the shadows cast on sidewalks
or other pedestrian areas, including the plaza to the west of the Exeter Residences.
As described above, these minor changes are not expected to have any discernable
effect on pedestrian use of these spaces.
155-feet Zoning Height
The 155 foot Exeter Residences will cast new shadows within pedestrian areas at 3
PM and 6 PM on May 5 and August 5. The new shadows at 3 PM will fall on the
west-facing sidewalks of Exeter Street at Blagden Street and on the sidewalk adjacent
to the Copley Square Hotel. At 6 PM the new shadows cast by this building are
limited to the south west corner of the intersection of Blagden and Exeter Streets and
the Blagden Street sidewalk at the rear of 25 Huntington Avenue.
Impacts to the plaza to the west of the 155 foot Exeter Residences are limited to the
9AM analysis period.
Proposed Program
The proposed Exeter Residences will cast a longer shadow down Blagden Street at 3
PM on May 5 and August 5 than under the 155 foot development program.
However, these shadows cast towards the rear of the Boston Public Library and will
not reach the library’s open air courtyard. The additional height proposed by this
scenario will not increase the shadows cast on sidewalks of other public areas at 9
AM, noon and 6 PM.
155-feet Zoning Height
On June 21 at 9 AM, the 155 foot Exeter Residences will cast a new shadow towards
the roof and rear wall of Lord & Taylor and some of the adjacent plaza space, but
that shadow will not reach Boylston Street or the East Ring Road. At noon, the new
