Environmental Protection
This chapter was prepared for the DPIR to supplement the Environmental Protection
chapter documented in the NPC/PNF. Specifically, this section updates the
NPC/PNF and provides detail regarding wind, shadow, daylight, solar glare and
geotechnical components. The remaining environmental analyses studied pursuant
to Article 80 Large Project review guidelines are contained in Chapter 6 of the
original NPC/PNF document.
Pursuant to the BRA Scoping Determination issued on February 15, 2008, the
environmental studies presented in the NPC/PNF were revised and/or updated. A
complete list of environmental studies evaluated for the Project throughout the
NPC/PNF and DPIR processes is identified below in Table 5-1. In addition to the
studies continued in this DPIR, original documentation can be found within the
NPC/PNF Volumes I and II as stated in Table 5-1.
With the exception of wind, the updated environmental studies in this DPIR are
based on the Proposed Program of 27 stories or 311’ in height for the Exeter
Residences and of 17 stories or 242’ in height for 888 Boylston. The “Proposed
Program” on which the analysis of wind is based is a slightly more intensive
program of 19 stories or 265’ in height for 888 Boylston and 28 stories or 320’ in
height for Exeter Residences. Although the Proposed Program as presented in this
DPIR has been reduced from those parameters, the impacts of the more intensive
Proposed Program were satisfactory as to wind. Since the impacts of the modified
Proposed Program discussed in this DPIR will be less than the impacts of the taller
and denser proposal, the wind analysis has not been further redone to reflect the
currently reduced program.
The environmental studies in the NPC/PNF were based on a program of 30 stories
and 340’ in height for the Exeter Residences and of 19 stories and 265’ in height for
888 Boylston, which is more intensive than the Proposed Program as presented in
this DPIR.
