Hi Sara,
Here are comments from building:
1. Historic portion East property line fire separation distance of 3’-5” complies with IRC (change
in use to single family) if fire sprinklers are installed. (2015 IRC R302.1)
2. Historic portion West property line fire separation distance of 1’-0” requires 1 hour rated wall
and no windows or eave overhangs allowed. The existing condition is similar but with a few
more inches of clearance on the West (but then less on the East) (2015 IRC R302.1). However,
2015 IEBC 1205.3 allows the existing historic exterior wall and opening situation to remain
due to a change of occupancy to an equal hazard category. The applicant must submit a
report per 2015 IEBC 1201.2.
3. The new addition is 3’ from the East and West property lines. This requires either a fire
sprinkler or 1 hour fire rated wall with windows no more than 25% of wall area and 1 hour fire
rated eave overhangs no closer than 2’ to the property lines (2015 IRC R302.1). Applicant
should verify with the Parks department that a fire sprinkler line can feasibly be installed.
4. Emergency escape and rescue opening window wells have grates and appear to be adjacent
to walkways- requiring guards per City policy.

Sarah,
Engineering comments are as follows:
1.Stormwater - The application makes no reference to how onsite runoff will be captured and
treated for water quality. The proposed plan does not leave much room for stormwater
treatment. Prior to HPC approval the applicant shall provide information on a conceptual level
of how rainwater will be treated.
2.Excavation Stabilization - The proposed excavation stabilization plan is very constrained. If any
work or layback is proposed to be done on neighboring properties, an agreement between
the property owners must be submitted to the City along with the building permit. Micropile
walls cannot have any impact on neighboring properties.
3.Water service line – at building permit, the applicant shall work with the Parks and
Engineering Departments to determine the best alignment of the new water service line. Any
plan shall minimize impacts to the street trees. The application mentioned removing the tree
in the front yard so it is my understanding there will be no onsite utility tree conflicts.
4.Public improvements – at the time of building permit a 6’ sidewalk will be required. The
sidewalk shall follow the COA “floating sidewalk” detail to avoid tree roots. New curb and
gutter will be required. A one sided pour on the back will be required to protect the existing
tree roots. A 2’ asphalt t-top patch will be required.
Thanks,

Hi Sarah,
Parks comments:
On page 19, applicant is asking for a removal of the front tree. As there are two trees in the
front yard, 1 deciduous and 1 coniferous, we need to know which they are inquiring about.
What are the limits of excavation in front yard? This will require discussion with the City
Forester to see how close to the cottonwood trunks they can disturb.
On pages 5 & 30, Waiver request for Parks Dedication fees will need approval of Manager of
Parks.
DBH on cottonwood trees are the same on both surveys, one dated 9/24/2012 and the other
dated 3/21/2019. Will need to verify sizes.
If ENG is requiring sidewalk to be replaced it must be of a floating design and no excavation
can occur within the driplines of the existing cottonwoods.
Any activity in the front yard will require discussion with the City Forester as it is entirely
within the driplines of the cottonwoods. This includes staging of house while the basement is
being dug.
The waterline for both 202 and 208 W Main is in between the 2 cottonwoods and a discussion
will need to be had between ENG and Parks to determine the best location for the new
waterline.
