trafflc monltorlng included the lntel"Sectlons of 4th Street and
PlCO; PICa and NeIlson Way/Ocean Avenue; 4th Street and BIcknell;
and 4th Stl"eet and Ocean Park Bouleval"d. Further It was specIfIed
that the daytlme weekend trafflc could not exceed the Level of
SerVlce "D" In eIther lane on ~th Street. Level of Servlce "D" IS
reached when overall travel speeds have dropped to 15 mph, Delays
at Cl"ltIcal locatIons such as Cl"osslng of othel" maJol" arterIals
may become extenSIve, WIth some vehIcles occasIonally waItIng two
0:" mo:"e SIgnal cycles to pass th:"ough the Inte:"sectIon, These
condItIons may be tolerable for shOl"t pe:"lods of tIme Ol" at
occassional bottlenecks but c:"eate unacceptable delay when they
eXIst fo:" a conSIderable pOl"tlon of the peak hour along an entIre
sectIon of stl"eet. It was detel"mlned that the Level of Sel"VICe
"0" was 1048 vehIcles per hour for the southbound 4th Street
traffIC and 1604 vehIcles per hour for the nOl"thbound traffIC.
CIty staff collected traffIC data on a varIety of weekends
before the summer and through the summer. Included were the thl"ee
bUSIest summer weekends. MemorIal Day weekend, and Labol" Day
weekend and the 4th of July. AnalYSIS of the peak hour traffIC
data IndIcates that at no tIme dId 4th St:"eet t:"afflc exceed
Level of Servlce "D". In fact the Level of Sel"VICe of 4th Stl"eet
was "B" or bette:",
The average dally t:"afflc on 4th St:"eet has dec:"eased from
17, 000 veh~cles per day befo:"e the Improvements were made to
15,340 vehIcles pe:" day afte:" the lmp:"ovements were made, The
total dec:"ease ~s approxImately 1760 veh~cles pe:" day (see
attachments 1 th:"ough 4).
The average dally traffIC on Thl.:"d Street has Increased from
- 2 -
.
.
1340 vehlcles per day to 2280 vehlcles per day, Whlle the actual
percent Increase is hlgh, the average dally trafflc on 3rd street
1S Wl thln the gUldellnes establlshed In the Clrculatlon Element
for local resldentlal streets (attachment 5 and 6).
The average daily trafflc volumes on Nellson Way. Ocean
Avenue,
PlCO Boulevard
and Maln Street have been falrly
conslstent before and after the Improvements were Implemented on
4th Street (see attachments 7 through 13), ThlS Indlcates the 4th
Street Improvements have not had an adve.se affect on the maJor
a.terlals in the area.
Speed Analysls
The posted speed llmlt IS 30 mph on 4th Street between PlCO
Boulevard and Ocean Park Bouleva.d. PrIor to the Improvements to
4th Street over 63 percent of the trafflc was exceed Ing the
posted speed llmlt and 16 percent of the trafflc was exceedlng 35
mph, SInce the lmprovements have been lmplemented 14 percent of
the trafflc exceeds the posted speed llmlt and 3 percent of the
t.afflc exceeds 35 mph. Thls represents a 49 percent reductlon of
the number of vehIcles exceedlng the posted speed limit.
Accldent ~n~lysls
CIty staff conducted an analYSIS of traffIC accldents between
PICa Boulevard and Hlll Street lncluslve for a Slmllar tlme
perlod before (1/83 to 9/83) and after (1/84 to 9/84) the
lmprovements on 4th St.eet were Installed.

pa:-ked In the medIan. ThIS was the only accldent involvlng parked
vehlCles In the med lan. Before the Improvements there were 3
pedestrlan :-elated accldents and after the lmprovements there has
only been one pedestrlan aCCIdent,
Cltlzen Concerns
Cl ty staff has not recelved any wrItten or oral complaInts
about the 4th Street lmprovements In the last 6 months, PrIor to
that tIme the most frequent complalnt was In regards to
aesthetIcs, vehIcles parklng In w:-ong dl:-ectlon and vehicles
crOSSIng over the paInted medlan. These concerns can be mItIgated
by lnstalllng a raIsed landscaped medIan.
PubllC Mee~ln~
Clty staff held a publIC meetIng on December 10th at John MUl:-
Elementary School to reCelve lnput regardIng the temporary
changes and the p:-oposed permanent InstallatIon. There were 13
resldents from the area who attended the meetIng. Ten out of the
13 reSIdents strongly supported the temporary changes and wanted
the permanent InstallatIon Implemented, They IndIcated that
vehIcle speed nOIse levels and traffIC volumes have decreased and

.
the safety to pedestr~ans ~ncreased, In add~t~on, they were
extremely pleased w~th the addItlonal park1ng pl"ovlded In the
med lan. One concern shal"ed by all was the aesthet1cs of the
prOJect.
Two of the al"ea l"es~dents were in favor of the permanent
~nstallat1on ~f some mod1flcat~ons can be made to the plans, One
resldent has problems eXltlng h1S dr1veway. Staff has mod~f1ed
the proposed plan to m~t~gate h~s concerns. The other res1dent
h.ke the ~dea of the medlan park~ng but felt that the reduct10n
of travel lanes had not reduced speeds and volumes and created a
cont1nuous llne of trafflc wlth l~ttel or no gaps In trafflc to
eX1t thelr drlveway. In add~t~on, the no~se level had 1ncreased,
It
was
suggested
stop
slgns
be
~nstalled
at
all
the
Intersect~ons, Staff has rev~ewed th~s request and determ1ned the
stop SIgns do not meet the Clty'S requlrements.
There was one resIdent who was totally opposed to the
proJect, ThlS resldent 1nd Icates that all the traff1c 15 belng
d~verted from 4th Street to the alleys ~n the area to get to 5th
Street and then to Ocean Park Boulevard. Staff observed the
traff~c flow in the area and could not substant~ate a s1gn1f~cant
problem w1th veh1cles uS1ng the alleys.
