Bozeman MT, 59715 RE: One 11 2.0 RC
Garage Access Standard Deviation Request Shawn:
Please find the following deviation request from the access standards for the proposed garage parking access for the One 11 2.0 building. The proposed garage access, which functions exclusively as an exit, provides a through-way for the one-way traffic flow that accesses 14 parking spaces in the building. The garage exit is 28’ from the Beall Street right-of-way, less than the 40’ code requirement. However, the garage access replaces 2 existing parking lot access which are closer to Beall Street and access 47 existing parking spaces, so the proposed access improves the existing condition. This request addresses the information required per BMC 38.400.090.H.3. and shows that this access does not jeopardize the public’s health, safety and welfare, or the intent of this code chapter.
Deviation Request from Property Access Standards BMC Sec 38.400.090
H. Modifications of property access standards.
3. Commercial developments (including residential complexes for five or more households) which may not be able to meet the requirements of subsections C through E of this section, and are
requesting modifications from the standards, must submit to the city engineer a report certified by a
professional engineer addressing the following site conditions, both present and future:
a. Traffic volumes; The proposed garage exit replaces two existing accesses to the existing 47 space parking currently occupying this property. The existing east and west parking lot address are approximately 20’ from the Beall Street right-of-way. The traffic flow from the proposed exit is less than the current access
since it serves far fewer parking spaces. The access is additionally serving one way traffic flow as an exit only, which will reduce associated traffic volume impacts when compared to a traditional access.
b. Turning movements; Because the proposed access is exit only, the exiting turning movements will not dramatically interfere with nearby intersection turning movements.

c. Traffic controls; Grand Avenue is currently stop controlled at Beall Street, reducing vehicle speeds near the intersection, and improving reaction times. The proposed exit driveway exceeds site vision requirements. d. Site design;
The garage door is set back 15’ from the property line which provides adequate time to resolve pedestrian conflicts at the sidewalk.
e. Sight distances; and
Typical site vision triangle distances can be maintained. The current no-parking condition along the east side of Grand Avenue results in even clearer vision of approaches.
f. Location and alignment of other access points. Currently there are two approaches on the east side of Grand Avenue and one approach on the west side of Grand Avenue. As proposed, the two existing accesses on the east side of Grand Avenue would be reconfigured to three accesses, including the garage exit. However, the overall number of parking spaces accessed from Grand Avenue will decrease.
