STAFF UPORT
COIl9entlO1l ClI!Ilter Ro~Cin Ball Plaza Refurbi.........t
The purpose of this request is to identify specific problem areas and
recommend remedial corrective actions within the Convention Center/City
Hall Plaza. The attached report, dated November 5, 1991, quantifies in
detail the above referencad concerna. Following is a brief summary of the
analysia and recommendations.
1. Convention Center Roof
Over the last eight (8) years, there has been an increaaing occurrence
of water leakage and damage from the City Hall Plaza deck to the
Convention Center below (Convention Center roof). In the spring of
1991, staff contracted with an engineering firm to provide an opinion
of corrective action. Unfortunately, the proposed corrective measures
addressed a worse-case scenario with an estimated cost of over
$500,000. In light of the current fiscal restraints, staff in
conjunction with the engineering staff of the Karako/Convention
Center, proceeded to design alternative measures of remediation.
The proposed corrective measures are explicitly detailed in Chapters
I, II, III of the attached report. It is staff's and the
Marako/Convention Center Enaineer's opinion that the remedial action,
st a cost of approximately $41,000, would solve over 90S of the
problem for a period of up to ten (10) years.
2.
Planter... '..aft".eaDfftR aft" enaPd,...il
Located at the south end of the City Hall Plaza, contiguous to the
parking structure bridge, is an exlating paved planter. Upon staU's
inspection it has been determined that the existing condition poses a
serious public hazard (the details are addressed in Chapter III of the
attached report). Staff proposes remedial action consiating of the
removal of the existing concrete pavers, the installation of
irrigation and landscaping, and the fabrication and installation of a
guardrail. The estimated cost of these improvements is approximately
$5,000.
3. ReDair of City Ball Water Feature
Based upon the inspection of the City Hall Plaza area, staff has
determined that the water feature is in serious need of maintenance
and repair.

In summary, the water feature suffers from a failure of its interior
sealing membrane, an infestation of water beetles, a lack of water
treatment, inadequate proper ongoing maintenance (which is increasing
the deterioration of the structure and surrounding brick pavers), and
has no energy manaaement features (the pumps run 24 hours a day). The
detailed staff analysis and recommendations are in the summary of
Chapter V in the attached report.
Staff, therefore, concludes and recommends the repair and replacement .
of the pond's innerseal membrane, installation of an automatic
chlorinator and water filter and, installation of a time clock control
for the circulation pump. The total estimated cost for the above
proposal is approximately $20,500. The installation of the time clock
on the circulation pump would produce an estimated savings of
approximately $2,500 per year in electrical consumption.
Staff further recommends the contracting of an outside service
agreement for the monthly care of sald facility. This action would
ensure the consistent and proper maintenance and warranties of the
installation. Since recurring service payments are not eligible for
Community Development Commission funding ~ costs fo such
recommendations would become the fiscal responsibility of the City's
Public Works Department.
Maintenance costs, if ~, in connection with the implementation of
items 1, 2 and 3 above would have to be borne by the City's Parks,
Recreation and Community Services Department.
Bnd"et SvnoDsis
A synopsis of the total cost of the above five (5) proposals is as follows:
1. Convention Center Roof
a) Planters, Draws, Irrigation System Lawn
b) Mall Paver System Repair
c) Mail Landscaping
$ 14,500
$ 24,000

IlEVIEW
There 18 an onaoina probl. vith vater leakina frOll the overlyina deck
feature into the convention center. On inveatiaation I've found however,
that the leakaae really only appeara in .everal area. and doe. .0 on an
incona18tent bad.. Th18 it. hu been addre..ed over the year. and 1I0re
recently by the COllllultina EDaineedna fim 1lMJM. There 18 an attached
copy of their report in the appendix of thi. document. I .hall reference
it in the recOllllendation .ection of thi. Chapter.
The followina are the ob.ervatione of the valk-thru on Auauet 30, 1991.
1. There 1a an obvioua lack of control of the irdaation ayet. in all
the planted areae. Almo.t every planter at 1:30 p... in the
afternoon v.. completely .aturated vith vater and in .000e area. had
pool. of vater .tandina .. much a. a foot deep.
2. The lawn .re.. have arown over the yeara .0 now the natural arade
c.uae. vater to flov .vay froll their draina caudna pool1na.
3.
With the exception of one (1) planted area, none of the plantera
have drainaae weep holee. A. a coneequence, the over vatedna
create. huee water reeervoir. out of the plantere, with vater tryina
to find aD)' Yay to e.cape. Additionally, the landacape plantera
Where there are draine, the drain inlet arate i. above arade.
Therefore, preventina there function.
4.
MaD)' of the paved .re.. have lov .pot.. creatina larae area. of
pooled vater.
5.
The .ajority of the ele.tOlleric caulkina. which va. de.ianed a. both
a vater barrier and an up_ion joint. ha. become damaaed b7 ..e,
compre.dOll and .ub.idence. Therefore. the.e joint. are nov
re.ervoir. for vater.
6.
In aeneral, the paved area. have .tructurally adequate aroutina.
Bovever, there are eOlle areae that have .000e hairline cract. and
eOlle loo.e arout. Theee areae are lIore the exception then the rule.
It appeare that approximately one (1%) percent of the total paved
area. .uffer froll thi. condition.
7.
The vater feature on inapection appear. to be relatively watertiaht
in ita entirety. The addition of the "tid7pool" blue dye in the
feature haa actually helped to determine if there are .000e problema
vith vater tiahtneea of thi. f.ature. In inapectina the electrical
rooll directly underneath this area there appear. to be no blue dye
vhich vould danity aD)' leuina of the pool.
The detaila and analy.i. of thia vater feature viII be addresaed in
it. entirety in Chapter V of thia report.

The obvioua coal la to aolve tha lewae problem on a permanent baala.
It ahou1d be noted however, that thia roof ia a dynaaic not atatic
environment. Thla particular c..e la extremely unique. Thie la not only
a roof, it i. a1.0 a plaza deck area. It ia .ubject to conatant
pedestrian traffic, the~l upanaion and contraction and certainly the
occaalonal bapact of .atntenance and aenice vehic1ea. I've hava taken a
very ba.ic approach in my ana1yal. and recolDendationa. lirat, ualna the
fundamental pr..lae of ~ andyal. of vater 1ealtaae; never let vater
stand. In treatina a &yet_ where vater ia introduced to the envir01llllent
the most priaary coal ia to r_ove the vater frOlD that envir01llllent aa
immediately aa poaaible. Aa we know with our roofa at hOlDe when vater
standa on a flat roof it eventually finda a way to aet throulh it. I
have used thia pramiae aa the baaia of my recommendation.

To pro.,ide desian sltemati.,es for a existine condition that would
enhance the area esthetically and reduce the aerious and ob.,ious public
liablli ty.
JIlWIBW
The existina condition is a product of s deciaion to pave the landscaping
planter area sometille in the past. The modification was the removal of
the 1andscspe IIaterial in the planter and the installation of the
interlockina concrete paver. Dur1na the time since this inatallation the
pavlna IIateria1 has aubsided conaiderably.
With the aubsidence of the inter10cltina concrete pavers, there is a
serious "trip-and-fa11" hazard. The pa.,ina .ateria1s ha.,a dropped down
from the ori,ina1 plater curb, crestina e "trip curb" that .,aries from
one (1") to approzillate1y four (4") inches.
In addition, the ori,ina1 desian did not anticipate a need for a
,uardrai1 between the plater area and the tiered platers transition to
the ,ara,e. This area is extremely danaerous. Especially if there are
any children which .~ p1~ in the area. In theory, they could be
attracted towarda the step tiered planters and potentially fall down the
planters fifteen (15') feet below to the bottom of the ,arage.
DCOJlll'l&llIJ.&.'PTOD
This section is broken down into two (2) are.., the firat beina
"Liabilities", second beina "Aesthetics";
See~iOD "AM Li.bilt~t
It is imperati.,e that a ,uardrai1 be installed, directly adjacent to the
planter/sidewalk UldIor at the head wall of the tiered 1andacape
planters. This erea is currently a extremely hiah lisbility for the
City. The selection of which ,uardrall to be installed, would be baaed
upon the aesthetic treatment of the planter.
If the decision is ..de to 1ea.,e the planter as ia, a guardrail should be
installed between ths sidewalk ad the pa.,ed plater area. This would
prevent individuals froa steppina off and/or trippina into the existina
condition where the pavers have auba1ded. If the area is to be
1andacaped, I recommend that the ,uardrai1 be fabricated and inata11ed at
the head of the tiered 1adacape plater, directly to the aouth of this
plater.

Certainly the most aesthetically pleasina proposal would be the removal
of the .xistine retrofitted concrete pavers. They would be replaced by
an irrication system, underlayina soil medium and either sod turf crass,
or around cover material.
COSTS
Bither propossls as mentioned above could be accomplished approximately
in one (1) weeks ti.e and includina auardrails would cost approximately
$1,500 to $5,000 dependina on the combination of options.

To deaian an alternative which would enhance the deaian and function of
the City Ball pODdina and water feature.
IU5V~KYl
The exiatina vater feature conaiata of multiple ponda that are connected
by cucadina wiera. The ortlinal deatan had a apray feature at the top
of the water courae followed by a aucceedina .erie. of reflectina pond..
The reflectina pond. vere connected by a .erie. of pebbled ca.cadina
wtera. The overall effect va. to provide the .ipt of PODdina vater and
the .ound of eaacadina vater. It '. deatan i. a. Gece..ful today a. it
waa when it va. orilinally created. lapedally wen lWlaaed properly.
D~K.IIA""OIIS
Thi. water cour.e ia extremely intere.tina in ita orilinal and exiatina
deaian and atate. It doea howeVer, lend itaelf to an alternative that
.hould be conaidered.
1.
Could the ex1.tina water feature be modified for an aquaculture
environment (Waterplanta)?
2. Could tha aziatina deaian and propoaed aquaculture accommodate
ornamental fiab and marine life?
I recommend that a de.ian architect wo .pecialiae. in vater featurea and
aqua culture environment. be contracted to provide a two (2) phaae
.tudy.
l'ha.e II Analyae the exi.Una feature in an .ttempt to clarity ita
de.ian and viability to accommodate an aqua culture environment.
Pha.e III If l'ha.e I conclud.. that tha azi.tina de.ian will accommodate
an aquaculture environment; .) Deatan . water landacape
environment conai.tina of planta in pota; b) Create a apeciea
liat of fi.h and marine life; c) Provide a recommended
maintenance .chedule for the planta and nah.
ESTDU.DD con
Thi. i. an extremely apeci.liaed requirement and certainly a very unique
field. I have only been able to find . .inale de.ian architect and
conaultina contractor to provide me vith the eat i_tea (See the followina
