any potential effects to water quality (see generally Section 3.11.3). For additional information regardingthe planned remediation activities in the PHSH district, including the remediation of Landfill 10, seeSections 2.2 and 2.2.1. See also Revised Feasibility Study for the Main Installation Sites (Presidio Trust2003d).A separate section to further characterize environmental conditions within the PHSH district to evaluatethe potential impacts from all alternatives is not necessary or required. The potential impacts associatedwith each alternative, including Alternative 2, are adequately discussed in the SEIS and will be avoided ormitigated. For further information regarding remediation activities on sites in and near the PHSH district,see Response to Comment ER-1.The SEIS includes mitigation measures that would minimize adverse effects on the Lobos Creekwatershed and groundwater basin, including eliminating any potential degradation of water quality due torunoff. Among the mitigation measures identified is the maintenance of existing and new drains andculverts to ensure that runoff is not altered or diverted toward Landfill 10 or toward Lobos Creek (seeMitigation Measure NR-15 Water Resources Best Management Practices in Section 3.11.3 for moreinformation). With respect to Alternative 2, any alteration to the existing basement structure in thevicinity of Building 1801 and Landfill 10 will be completed in a way that prevents alteration ofsubsurface groundwater flow. Further, “[d]ue to the presence of hazardous waste underlying the largeparking area west of the PHSH, the diversion of subsurface drainage around the underground parkingfacility will not divert toward Landfill 10” (see Mitigation Measure NR-15).1.16 OTHER TOPICS (OT)OT-1. Sustainable TechnologiesThe SFPUC encouraged the Trust to include in the SEIS project-specific sustainable technologies thataddress the use of recycled water, minimize storm water runoff, and incorporate storage and reuse. SPURexpressed interest in the applicant’s intention stated in the SEIS to incorporate sustainable developmentand building practices leading to a Leadership in Energy and Environmental Design (LEED) rating.Response OT-1 – The requested project- and alternative-specific information cannot be made availableearlier than the design phase (i.e., 100-percent construction documents), as the Trust will not select aprivate development partner that will develop the sustainable measures until after the environmentalreview process is completed and the Record of Decision is signed. Nonetheless, both development teamshave expressed a keen interest in green design and LEED certification.
