RESPONSE TO COMMENTS ON THE DEIS<br />
B o u l d e r B a y C o m m u n i t y E n h a n c e m e n t P r o g r a m P r o j e c t E I S<br />
Comment 335-k: Comment Summary - The EIS needs to provide evidence that Alts. C and D, and CEP<br />
projects provide a substantial net water quality benefits. Post-project monitoring is<br />
not considered adequate.<br />
Impact HYDRO-1 is addressed on page 4.2-32 of the DEIS. Post-project monitoring<br />
will be completed to further calibrate predictive models and substantiate assumed<br />
effectiveness of the proposed stormwater treatment systems, BMPs and LID<br />
strategies. The supplemental analysis in Appendix AB for further quantification of<br />
the water quality benefits.<br />
Comment 335-l: Comment Summary - The HYDRO-1 mitigation: the security deposit fee does not<br />
guarantee that the mitigation will be accomplished for water quality.<br />
The security deposit will be determined by TRPA once an Alternative is selected for<br />
permitting. The comment is noted that the security deposit should be an amount that<br />
is adequate to "cover additional, best available control technologies that could be<br />
implemented in addition to the planned systems if post-project monitoring shows that<br />
standards are not being met".<br />
Comment 335-m: Comment Summary - The EIS should disclose landscaping and fertilizer use.<br />
The Landscaping Plan will be developed in accordance with the selected Alternative<br />
and submitted to TRPA for approval during project permitting. The Landscaping<br />
Plan for Alternative C is included in Appendix O of the DEIS. The EIS discusses<br />
proposed landscaping on pages 2-17 for open space and parks and 2-26 for the high<br />
traffic areas in the pedestrian village. The Revegetation/Landscaping Plan is<br />
identified as a standard practice (SP-7) for the Project for compliance with TRPA<br />
codified regulations and is outlined in Chapter 6, Mitigation and Monitoring<br />
Program. Chapter 4.3 further discusses the requirements of the<br />
Revegetation/Landscaping Plan for disturbed areas on pages 4.3-25.<br />
Comment 335-n: Comment Summary - Describe if the stormwater treatment train will work with snow.<br />
The statement that the calculations on pages 4.3-40 to 4.3-41 assumes that only rain<br />
will fall is incorrect. The stormwater treatment system, which is primarily composed<br />
of underground components such as infiltration trenches and galleries are properly<br />
sized and located to treat "runoff" into the systems. The runoff will occur from rain,<br />
melting snow or a combination of rain and melting snow. Snow that falls on<br />
portions of the project area will be melted through advanced snow management as<br />
described on page 4.3-28 and captured and conveyed to the stormwater treatment<br />
systems. Snow that falls in above ground infiltration basins would affect the<br />
functioning of the basins by reducing the total capacity; however, runoff that<br />
eventually enters a basin would serve to melt this snow and recapture this capacity by<br />
initiating the melting and infiltration process.<br />
Comment 335-o: Comment Summary - Verify if 100-year storm runoff will be treated.<br />
See Table 4.3-12. See Appendix AB, which includes the LID summary table (termed<br />
Green Strategies) and support calculations (Table 1).<br />
Comment 335-p: Comment Summary - Provide documentation to support the quantified benefits of<br />
green roofs, previous pavers, and stormwater catchments on the treatment system.<br />
DEIS Appendix R details the support data and references for the LID strategies. The<br />
assumptions documented for the LID strategies are based on studies for cold weather<br />
climates and are conservative. For example, the effective reduction for pervious<br />
