Infrastructure Systems
This chapter was prepared for the DPIR to supplement the Infrastructure Systems
chapter documented in the NPC/PNF. Specifically, this section provides detail
regarding the groundwater mitigation/management, monitoring and recharge. The
remaining infrastructure systems studied pursuant to Article 80 Large Project review
guidelines are contained in Chapter 7 of the original NPC/PNF document.
The Exeter Residences and 888 Boylston Project Sites are located within the limits of
the Groundwater Conservation Overlay District (GCOD), pursuant to Article 32 of
the Boston Zoning Code. The proposed building sites are located over below-grade
parking garages and neighboring tunnels which serve local transit and state
roadways. Based on the existing site constraints, few opportunities for recharge of
stormwater are available. However, the Proponent will work with the Boston Water
Sewer Commission (BWSC), Boston Redevelopment Authority (BRA) and Boston
Groundwater Trust in order to respond to the Article 32 requirements. Through a
series of coordination meetings, potential recharge areas have already been identified
to provide groundwater recharge opportunities, as discussed below.
Stormwater management controls will be established in compliance with BWSC
standards. The Proponent is committed to controlling peak flows, pollutants and
sediments entering into the receiving waters of the local BWSC stormwater drainage
system to the extent practical. The drainage design will be reviewed and approved
by the BWSC as part of the BWSC Site Plan Approval process following the Article 80
Large Project Review process.
