HomeMy WebLinkAbout005.03 - Appendix D.3 - Ida Connection Traffic January 29, 2025 Mr. Scott Baldasare Jackadoo, LP Brick Capital 1907 Pine Street Philadelphia, PA 19103 Reference: Block 104 Traffic Impact Study, North Ida Revision Project No. 06020.11 Dear Mr. Baldasare, The purpose of this letter is to review any impacts from the North Ida Revision of Bozeman Yards. Traffic impacts from the Bozeman Yards were previously evaluated in the Block 104 Traffic Impact Study (TIS) completed by Sanbell (formerly Sanderson Stewart) in December of 2023. A Trip Generation Update Addendum letter was completed by Sanbell in December of 2024. It was requested by the City of Bozeman that an alternative street design be completed that maintains the section of North Ida Avenue between East Aspen Street and Front Street. The original TIS assumed that this segment would be vacated. However, this slight change in adjacent roadway geometry is unlikely to result in a significant impact on the findings from the original TIS. The current Bozeman Yards site plan proposes 26 units in the north building and 42 units in the south building for 68 total dwelling units, with 1,759 square-feet of commercial retail use also in the south building. These uses are projected to generate 373 daily external trips, with 29 new external AM peak hour trips and 33 new external PM peak hour trips. The original TIS evaluated trip assignment and future operations based on the assumption that North Ida Avenue would be closed between East Aspen Street and Front Street. With this segment remaining open, some small changes to the original trip assignment may occur. Trips entering or exiting from the east side of the site may now utilize North Ida Avenue to access East Aspen Street instead of passing through the East Aspen Street/Front Street intersection. This would result in a Mr. Scott Baldasare January 29, 2025 Page 2 reduction in volumes at the East Aspen Street/Front Street intersection and a shift in movements at the North Ida Avenue/East Aspen Street intersection but would not change the overall trip numbers entering and exiting the site. No other intersections would be impacted by the change in configuration. The highest volume of reassigned site-generated vehicles would occur for egress trips during the AM peak hour. This change in site trip routing would not have a measurable impact (operations or safety) on the projected total future volumes at these intersections. Therefore, no change is expected to the projected future traffic operations or any traffic related recommendations contained in the original TIS. All findings presented therein remain relevant and should be implemented with exception of those recommendations specific to the closure of North Ida Avenue. With North Ida Avenue maintained, the new site access approach will create a five-leg intersection with North Ida Avenue and Front Street. Based on professional recommendations for traffic operations and safety elements as well as guidance provided by the City of Bozeman Public Works Director, this intersection should be stop-controlled on all approaches to avoid driver confusion and encourage safe operations. Additionally, with extension of East Aspen Street west of North Ida Avenue, this new four-leg intersection should also be stop-controlled on all approaches. If you have any questions or concerns on the above analysis, please feel free to contact me at 406-922-4306 or jstaszcuk@sanbell.com.
