Hans,
This preliminary review of your proposal looks acceptable.
Final review and acceptance will be when you apply for your building permit and this will be reviewed
far more in depth by that department fyi. You appear to be meeting the intent of our requirements.

Importance: High
Good Afternoon
I hope you had a good New Years.
We have a revised building design to address the fire comment. We had submitted it to Jill along with
all the other information for the application.
She has asked that I submit it to you first to get your review of the fire wall issue.
I am attaching three files for your review.
I’m not sure if you need the structural plans or not.
Please let me know if this is enough and if you have any comments.
Thanks
Hans

Good afternoon
Please reference the email below and the attached copy of a 2018 pre-application
meeting comment sheet.
From my reading of the 2018 sheet, there is a 1,750 gpm requirement for this 2
lot townhome project. It was not clear until now that the 8” main in Hardie can
only provide 1,250 gpm.
Can you please let me know what options are available to us to reduce the
required fire flow ? We assume the two townhomes will be sprinklered.
Please let me know what additional information your require.
Thanks in advance for your help.

Pavel,
That is not how we interpret it. We have a local fire code amendment for fire walls for the purposes of
fire flow reduction that specifically requires the 30-inch parapet. See attached below in red. I remind
you also that it is required to be a four hour rated wall.
108. Appendix B104.2, Area separation, of the International Fire Code, 2015 Edition, is hereby amended
to read as follows:
Appendix B104.2 Area separation. Portions of buildings, which are separated by one (1) or more four (4)
hour firewalls constructed in accordance with the International Building Code, without openings, and
provided with a thirty-inch (30") parapet, are allowed to be considered as separate fire areas. (Ord.
4547, 7-24-1995; Amd. Ord. 4769, 3-8-1999; Ord. 5086, 6-21-2004; Ord. 5404, 7-21-2008; Ord. 5556, 10-

Jill,
My main concern, that I don’t see addressed in the pre-submittal, is the fire flow. During the Pre-app,
the Applicant was given a fire flow estimate of 1,750 gpm for the proposed townhomes. The existing 8”
water main on Hardie can only deliver 1,250 gpm.
The Applicant must work with RFA to reduce the fire flow demand down to 1,250 gpm before we can
accept an LUA

Hi Jonathan,
You and I did a pre-app several years ago (2018) and the applicant has just submitted for a pre-screen
review. It is a proposed 2 lot unit lot subdivision for the construction of a duplex. Could you take a look
and let me know if you have comments on their submittal? Also can you complete the waiver in Energov
for any submittal items (Traffic Study?) that you may not need for your review?
