Transmitted herewith 'is a copy of the site pian for the subject apartment complex with the Fire
Marshall's comments shown thereon. Note that the Fire Hydrant locations are slightly
different than those discussed at out meeting list 7`hursday. I trust you Va'111etJeff Freiberg of
Harper -Leavitt know of these changes.
The Fire Marshall was still concerned about the location where the fire truck would hook onto
the building sprinkling system. He said the Fire Hydrant location mai change somewhat
depending upon where this fire truck/building fire sprinkling system hookup was located.
rrhe Flre Marshall indicated that some of the corners of the aisles needed to be "rounded off"
somewhat so the fire trucks could -get around them.. He said that a 26 Vit. radius at these comers
has shown in red an the returned plans) would probably be satisfactory for the fire trucks turning
requirexnents.
Would the northerly driveway be better if it were aligned with the east -west a%sle?
If guay fixes 1-1yuriihaxt # Vjlla ' t1-1-armro

With all the apartment buildings being designed dere in Rexburg, we have had lots of questions
raised about various items and the applicable UBC Sections. I've copied the parts of the UBC
that have generated the most questions and marded them 'in yellow. They may or mai not be
J0
Mems that are applicable to your development, but I thought it mai be helpful to send them out to
all firms designing apartments here to help you all meet what seems to he a universal and almost
impossible design/construct schedule.
Installing a �priinkfing system to fulfil the requirements of tMC Seen 904.2418,7 takes care of
allowing a 3�� floor., It also says you can have n3oxe than 16 dwelling units in the building so Y0 -U
don't have to divide it up into smaller buildings with 2 -hr. area Separation Walls. However,
note that UBC Sec. 5Q8 says that the addition of the sprinkling system to allow the 3' floor: Ushall
not waive or reduce the required fire -resistive construction for:
3 --� Area Separations knot needed as the sprinki�.g system eliminates the need for spx�zr�k��ng
systems if there are more than 16 units).
4 ___ Dwelling Unit Separations (i.e. there soil has to be I -bx walls separating all dwelling units).
emote that SBC Sic. 310.2.2 says that. "occupancies more than two stories in height or
having more than 3,000. sq.ft. of floor area above the first story shall not be of Tess than Qne-
haur fire- resistive construction througho ut except as provided in S ec. 60 1. 5 2. 2e5' Both
UBC Sec. 506 wid Seg. SDS indicate that the sprinkling system used to get the 3"d floor
cannot be used to also provide the, increase in rating ftom Type VN to Type V- l hr.
6 tl-m Corridors (Secs. 1005.7
and 1.005.8)
( A 1 -hr. wall

of course, this
would also be

As a follow-up to aur meeting on April 3Q, I am documenting decision. that were rade at
that meeting. The discussion �ncluded Joe Laird, yourself-, Jahn Millar, Jarred Sommer who
represents Nauvoo House.
It was derided at that meeting that on the Shelboum Complex that you would work
directly with your Domer to arrange for the engineering approval in construction of the utility
4L
dines that are on-site and also for the sewer line which rans north/south along the west side of
your building
It
It was also determined that Nauvoo mouse would work with their developing engznccr
and contractor to install any on-site utilities including the sewer line which runs alon, the west
side of their building.
The City will negotiate a contract with HWer-Leavitt to do the engineering services on
those utilities which he wifihin the road way right-of-way and also the curb, gutter, sidewalk and
road construction involved within the City right-of-way.
it is anticipated that the cost incurred by both developers for utilities which serve
properties beyond current exciting uses will be eligible for financing through the Local
Improvement District Program. Those utilities which serve only the on-site meds cannot be
included in the L.Q.D.
A determinat;on needs to be made with -the City F��ancial Office,*- as fo whethe_r or not the
itY can front fhe cost for the utility extenslons nt"Quch time Thai tis coln1c, d d and
bonds can be sold..
Both developers w1ii I retain an architect or engineer to supervise the construction of
I
Utilities involving their res ective
P projects and City will be copied on all inspection reports and a
We4a ,,kly log oftesting and inspections will be fimiished to the City Engineer, It is also important
that as -built drawings be maintam'ed and that once the work '

that they can be included xn the Local Improvement District. Reasonable engineering neen"ng or
architectural cost can also be 'Included in the 'incurred cost for the Local Impxovement District.

We will be meeting the week of May 3"dwith the City Financial Staff to determine the
exactly what procedures need to be followed for interim financing of the utility extensions ons or
other work that will be involved in the Local Improvement District. If you have questions or feel
that this letter does not adequately represent the discussion made at the meeting please contact
