Comment Letter 103 – Dahlgren Ph.D., Joy, 12/16/2009<br />
Comment 103-a: Comment Summary - Alt. C would increase trips and VMT because of additional<br />
workers and visitors to the site.<br />
Trip generation for Alternative C includes employees, guests, and non-guest visitors<br />
to the site. Please refer to Master Response 2, which compares the Proposed Project<br />
and Alternatives to an alternative existing baseline.<br />
Comment 103-b: Comment Summary - Alt. C trip generation estimates fail to consider external trips<br />
by guests to regional recreation, retail, and services beyond the Project Area.<br />
External project traffic estimates (vehicle trips in/out of the project area) include trips<br />
to the Project that are attracted to the onsite project amenities (non-guests) and trips<br />
to/from the proposed hotel/residential/interval ownership uses on the project area to<br />
other destinations (such as recreation, shopping, etc.). Master Response 3 provides<br />
additional clarification on internal/external Alternative mode trips. Master Response<br />
4 provides additional detail on project trip generation associated with accessory uses.<br />
Comment 103-c: Comment Summary - The EIS should disclose the base "Interacting Uses" numbers<br />
on which the "Internal Capture" numbers are based, and the interacting uses for the<br />
all "Raw Trips."<br />
Information on the interacting uses is provided in Appendix W of the DEIS. Master<br />
Response 3 provides additional clarification on internal/external Alternative mode<br />
trips including interacting uses.<br />
Comment 103-d: Comment Summary - The EIS should explain why Alt. C and A have different internal<br />
trip capture rates.<br />
Internal alternate mode rates, including on-site internal capture and off-site alternate<br />
modes, were developed specific to the type, size, and mix of the uses proposed for<br />
each Alternative. The number of internally captured walking trips between the<br />
project land uses was calculated by balancing the trips to correspond with the<br />
capacity of the lower trip generating use. Further explanation of the methodology<br />
used to calculate internal capture trips, as well as a visually representative figure, are<br />
provided in Master Response 3.<br />
Comment 103-e: Comment Summary - The trip generation numbers are incorrect. Trips were double<br />
counted when “Alternative Mode Split” factors were applied to the total number of<br />
“raw” trips, rather than only to external trips.<br />
The Alternative mode split and internal capture calculation were applied<br />
simultaneously to the raw project trips for each land use separately. There was not<br />
one percentage applied to the overall raw trip generation rate. The calculations were<br />
performed so that the internal/external alternate modes were analyzed based on<br />
specific land use type, size, and potential to interact with other on-site uses, off-site<br />
uses in close proximity, and transit opportunities. The Fehr & Peers Mixed Use<br />
Model and research looks at internally captured trips and off-site alternate mode trips<br />
as overall alternate modes because internal trips for mixed use sites are made via<br />
walking, bicycling, or transit depending on the size of the mixed use site. The model<br />
provides the overall “alternate modes” percentage for each use, which includes<br />
internal and external alternate modes, and a summary for the uses. The Fehr & Peers<br />
Mixed Use Model and research has been submitted to ITE, and will likely be<br />
included in future versions of the Trip Generation Handbook. The Fehr & Peers<br />
