City Manager's Report
TO: HONORABLE CITY COUNCIL
FROM: CITY MANAGER DEPARTMK'>'T: PLANNING
AGENDA DA IT: April 24, 1995 CJlfR:224:95
SUBJECT: BryantlAdd'"lSOll Traflk arcle (C[p 1 Slll} -Budget Arnendmo. t Ordin. DC~
REQUEST
Council has previously directed staff!o proceed with the design and construction cf a
permanent traffic dICIe at the Bryant! Addison intersection. lbe design work has
progressed through the conceptual design .tage. AI this point in time, it is evident that
additional funds ($9,000) are needed 10 prepare the final engineering plans aad
specifications and construct the project The PUl]Xl5e cf this report is to request thaI
Council approve a transfer cffunds ($9,000) from the Street Improvement Fund to the
Iraffic circle CapitallmprovemeDI Program ( ClP No. 1921 2).
RECO~ENDATIONS
Staff recommends that CouIlCiI adopt the &ttached Budget Amendment Ordinance
(Altacbmenl: 1) transferring a \OOlI of $9,000 froID the City's Street Improvement Fund to
aP No. 19212. in order to provide sufficient funds to prepare the fmal engineerillg plans
and specifications for the Bryant/Addison Traffic Circle.
POLIcy IMPLlCA nONS
Council has already approved the installation of a permanent traffi<: circle at the
BryantlAddisoo intersection. Traffic circles are one of several measures that are avaIlable
roc neighbo<'bood traffic management
The Public Works Department has expressed !he legitimate concern that !his proje<t, like
other similar traffic management de>ices, cootinues 10 incrementally a<'..d to the regularly
required need for maintenan~e without any concomitant budget adjustmeot for
maintenance and landscaping. In additioo, maintenance of the circle may require services
that are not included with current staff (e.g. !rick mason) or for which funding is not
aVailable in the Publics Works Budget.

The installation of!he traffic circle is on lop ofa "umber of underground utilities. 'WI)J1e
provision is being made for noanal ser.;';e ""cess, there will likely Wille a time when 2
po<tioo of the drde would have to be removed &-.d replaced, in order to accomplish the
needed wode. The most likely identifiable need is the storm dcain S)'stem. which may be
replaad within the ne'" five to ten year time period,
EXECUTIVE SUMMARY
Backeroond
InSep!ernber 1994 (CMR:436~4; Sept=ber 19, J994),the City Council approved a staff
recommendalion to retain the teI11jXlfary traffic circle at the Bryantl Addison intersection
and directed staff 10 proceed "ith the design and illstallation of a pennanent traffic circle,
with the understanding that it was to be done with the involvement of the neighbors and
should reflect the bistorK nature 0{ ibe neighbo.-hood. The traffic circle is one element
«the Bryant Street Bicycle Bouleva,-d Extension Project which W2S implemented in the
fall 0{ 1992.
The September 1994 staffrepon indicated tint a conceptual-level cos! estimate for an
irrigated. landscaped circle is approximately $25,000 to S30,OOO. A design that is
compatible with thehis10rK nafure oflhe neighborh<><Xi coold result in a cost S"'1'assing
$30,000. The staff report noted loat the City bad access 10 a remaining balance 0{
$45,000 0{ State Transportation De\'elcpmenr Act (IDA) funds that could be used for the
project. subject to certain deadlines: (oj cO!lS!ruction contraol approval by June 30, 1995
lind (b) construction completion by September 199 S. Otherwise, the Metropolitan
Transportation Commission will allocate UDuy-d funds to OIher projects.
St.afi's original intent was 10 try 10 eSlablish a "oI>.:n!eer working group of residents,
induding design prof""iona\s, 10 actuaTIy develop the design of the cirde, \hereby
ensuring that the design wO',w be acceptable to the neighborhood and saving the cost of
!he design work. As illumed out. res'.dent5 ar.d design professionals were willing 10, and
did, in fact, wntribme substantial time and effort 10 the conceptual design development
efJOrt. However, they were no( ahle 10 S<Jb:,iitute fur the need to hire consultant expertise
to do the actual conceptual design work: a me final engineering design work:.
Therefore, an urban design consultant -Greg Turg of Freedman, Tung and Bott<>mJey -
was hired, at a COS! of$1 O,OOt\ to develop the CO!lC<>ptual design for the permanent circle
that would echance and complement the historic aspect of the neighborhood. A
neighborhood working group was assembled 10 work: wiib W,/'. Tung in developmg flfS!
a preliminary conceptual design and, subsequently, a fmal coocept design. Members of
PaJ,e-2 ofS

o
the worlcing group include residents living on !Pree of the corners of the Bryant! Addisoo
intersection, three design professionals living near the circle, and a staff representative
from the City's TranSjlOltation Di,'sioo.
Concept Plan
The coooepruat design devel<lpment work h .. proceeded through several iterations of
al~.ernatives and variations and included the involvement of the neighborhood working
group as wen as an opportunity for broader neighborhood input; review by l:>oth the
Historic Resources Board (HRB) and the Ardlitechtual Re"';ew Board (ARB); and re"';ew
by affected City departments
The initial concept plan (estimated 1<> cost $50,(00) was subsequently modified to
address. to the extent possible, specific feat'JJe5 that raised concerns duri.'1g the review
process, as wen as 10 reduce the overall cost. The final coneept plan, as de><:nbed and
iIIustraled in Attachment 2, addresses !he concerns raised during the review process and
is currently estimated to cost approximately $35,000.
The next R'qUired step is the preparation of engineering design plans and specif",atioo thaI
can be nsed 10 proceed with the solicitation of bids and tV.e construction of the circle. The
estimated cost of sL>ch semees is $9,000. Startlng with the original sum of $45.000,
utilizing $10,000 for the concept design work and estimating a need for 535,000 for
coostructioo, leaves 00 remaining funds for the engineering design work. Therein lies the
genesis of the need for the subject Budget Amen<!ment Ordinance to pro,ide an additional
$9,000 to fund the cost of the engineering design worlc
Al!ernatiyes
The issue before Council at the present time is whelher !o approve a Budget Amendment
Ordinance that would provide an additional $9,000· for the completion of the
Bryant/Addison traffk circle. The alternatives are as foLIo\.\·sc
Alternative I:
Al!em.live 2:
CMR:224.:.9S
Aooreve the staff recommendation and,,~ the_~na,hed Budget
A,nendment Ordinance. Staff would then proceed with the
engineering design "ork which is required 10 bid and construe I the
project as now prQ9OSl'd.
Do not aweve the attached Budget Amendment Ordin~""ee and
!li!:ect staff to reduce Ihe estimated C05t 10 construct the circle, by an
amounI sufficient 10 cover any remaining engineerin..gdesign work.
for example, if the cost 10 construct the c irele could be reduced 10

Conclusions
-.. "~ .
o
$26.000, there would be $9,000 aVOIlable fOf required design work.
II is staff, con"idered opinion that any such further reduction would
significantly aher the basic design COIlCept and would necessitate
starting over cr going 10 ail "ofi"tlJe s.lJelf' design. In either case, Ibe
decision rogarding a new de sign would return 10 the neighborhood
worlcing grOllp.
Staff believes that the proposed circle design is a good one and has Ibe supp<>rt of the
residents. including design professionals, who live in the inuneiliate "'.emily. It bas been
reviewed by the HRB and the A.~B and is generally acceptable to the City departments
Ibat will be affected by its installation and need foc maintenance. To start over with
aoodler design eoo<:ep!. at this point in time, would be unwise and inefficie!lt utJ1ization
of resources. It would also most certainly result in L':te 10< s of State TDA funds that are
now avrulable 10 Ibe City foc this project
NcXlSteos
If Council approves the attached Budge! Amendmer.t Ordirumce. slaff will proceed ·with
Ibe hlHowing steps:
a Cootract witb a consultant 10 prepare the necessary engineering plans and
specificaiioo.
b. Proceed with bid procedures 10 select a coolraclor 10 construel the circle.
e. Return to Couocil. prior 10 June 30, 1995, for award of a construction contract
d. Construction of the circle will need to fulJow expeditiously. with completion by
September 1995.
F1SCAL L"IPACT
Appro\'3I ('(the attached Budget Amendment Ordinance ",ould transfer $9,000 from the

Boulevard Project. and Council approved a Negative Declardtion for this project at its
