We have prepared this memo as part of our Preliminary Plat application for Gran Cielo Block 4
Minor Subdivision. This memo hopes to address the comment provided on our Gran Cielo Block 4
Minor Subdivision Pre-Application. The comment is provided below:
” - A.11 – Streets, roads, and alleys. Provide a supplemental memo from a professional engineer
registered in the State of Montana demonstrating that the existing streets serving the subdivision
have adequate capacity for the proposed additional lots.”
Included in this memo is evidence to support that the existing roadway infrastructure capacity can
support the addition of 2 lots.
Streets Roads and Alleys
It should be noted that a TIS waiver has been given to us from City of Bozeman. Included in this
package is our correspondence with City of Bozeman about a TIS Waiver for this minor
subdivision.
With the addition of two lots, there will be two additional single family detached households. The
increase in subdivision traffic has been calculated using data from the Institute of Transportation
Engineers 11th generation Trip Generation Manual. See the table below for the increase in traffic
over the course of a week.

All roads were recently constructed as part of the Gran Cielo I major subdivision. The increase of
approximately 19 trips over the course of a single day or 2 more trips during peak hour
demonstrates the current local road capacity is sufficient.

Do not click links or open attachments unless you recognize the sender and know the content is safe. Hey Jake, We are in the process of submitting a Pre-application for a subsequent minor subdivision for Gran Cielo I Block 4 (see the attached plat). We want to add to 2 lots to block 4 (1-5). The result would mean altering those interior lot lines to have 7 lots instead of 5. We don’t have an assigned planner for this yet so we were hoping you could forward this to the appropriate person. I am reaching out to see if we could waive a TIS for this pre-app. Attached is the 10th edition land use list and the relevant code is 210 (Trips Per Unit=0.99), it can be assumed that 2 additional single family detached homes will be added. The 5 lots we plan on altering have a combined area of 0.69 acres. Please let me know if there is any more information I can provide to you for your convenience.
