The 2 existing 6” sewer services will work for the building if they are at a ¼” per foot(2%) slope. IF the 2 existing 6 “ sewer services are at 1/8” per foot slope (1%) then an additional 4” service will be required for the building.

Please see attached sheet C3.0. It was my understanding that we were planning to use both of the existing 6” diameter sewer services off of Village Crossing Way for the residential portion of the building. Then, cut a new 4” service in off of Village Downtown blvd. for the garage level items like the dog wash and janitors closet. Would it be possible for you to provide an official water usage calc to satisfy the city’s comment below? The applicant must provide water usage and confirm proposed water usage is within allowed capacity designated to the parcel upon further development. 2 As far as the part about “confirm proposed water usage is within allowed capacity designated to the parcel” don’t worry about that.

The sewer size leaving the building has been calculated out to be an 8”. The Fire sprinkler service will likely be a 6” service. Let me know if you need any other information.

I do not need a sewer calc. That is done.

Tanner has done some photometric plans and elevations for it. We’re submitting a final Site Plan modification for the project on Monday (the 22nd). Unfortunately the team missed one of the City of Bozeman comments and it was just brought to our attention on Friday. It’s in regards to the size of the fire service and domestic water service lines. In addition our civil engineer – Tim Staub at C&H, also copied on this email – is looking for a sewer calculation as well. I’m not sure if either of these items are long tedious tasks or something that can be done in 30 minutes? Either way, we’re looking for your insight if you have time. If you don’t have time on Monday, hopefully it’s something you could make time for in the coming weeks with the intent that when we get the comment back from the city again we could provide them with a answer quickly. Attached are the CAD plans of the building. Tanner has a revit model as well. -92 apartment units (mix of 1 bd, 2bd, and 3 bd) 3 -two bathrooms at the lobby -janitor room in the garage -dog wash in the garage Happy to catch up on Monday if you have time.

For now I can just add 5% to my sewer calc, but in the coming weeks it would be good if the mechanical could provide some flow numbers to help us satisfy this comment. The applicant must provide water usage and confirm proposed water usage is within allowed capacity designated to the parcel upon further development. The existing design report that the city has on file for this subdivision does not seem to match the subdivision as it exists. I think there were changes after the fact so verifying the allowed capacity is going to be a little difficult. Tim Staub, P.E.
