construction, why Ch. 10 applies to proposed floodway construction, how floodway construction will
meet no -rise certification standards, and how it will be re -certified for no -rise with as-builts.
o. Site boundaries in the Drainage Report appendix figures must be shown clearly and must be to
scale.
The repeat comments are the same as those offered during our previous review on April 29,
2011. It must be noted that updates to the Drainage Report were not received under this
submittal either, and must be completed before floodplain use permits for work in the flood
fringe or floodway will be considered.

Subject: Sanctuary West - Overall Floodplain Sheet 70
Bill,
Thank you for your help over the phone today at 4:00 PM. I would like to summarize my
findings on Sheet 70 of 70 of the Utility Plans, Titled Overall Floodplain.
The following comments in red text are still outstanding, as recorded in the summary
from Steve Olt by e-mail on Friday, Jan. 6, 2012 at 11:05 AM:
3. Floodplain comments (Brian Varrella) — Brian saw the revised Utility Plans for the first time today;
he did not have a chance
to go through all of his comments from the April 29, 2011 staff letter, but did note several of his
comments still had not been
addressed:
a. The overall floodplain exhibit has not been updated;
b. The floodplain linework is illegible.
c. Repeat Comment from April 29, 2011; Cross sections must reflect those used in the
floodplain modeling report.
d. The drainage sheets and grading sheets must reference the Overall Floodplain sheet.
e. Repeat Comment from April 29, 2011; Please add the following notes to the Plat,
Landscape Plan, Site Plan, Utility Plans (General Notes), Grading Plan, and Overall

fringe and floodway of the West Vine Basin, and are subject to the requirements of
Chapter 10 of City Code. (2) No storage of materials or equipment shall be allowed in
the floodway, whether temporary (during construction) or permanent. (3) An approved
floodplain use permit is required for all site elements (landscaping, fencing, roadway,
detention ponds, bike paths, parking lot, utilities etc.) in the floodplain prior to

and fencing within the floodway. Re -certification of no -rise is required for as -built
conditions. (5) See floodplain exhibit on Sheet 70 for cross-section locations, BFE lines,
and other additional floodplain information.

URS floodplain modeling report.
I. Repeat Comment from April 29, 2011; Drainage report must include a statement of why
