CLERMONT'S PROPOSED PROJECT PLAN

Canter L5ke is a 9. ï acre 1anå,Iodœd lake located between. West. Avenue and, EIghth StÆet
aIcrig the'.ncrth $de of H~.~'2Y SQ, within the Clenncnt'dr¡ Omits. c....~er Lake ¡aœives
.storm water IUI'1Oif ftcm an 82.3, ac:re drainage basin which' indudes a portion of Highway 50
fer 'the Florida ~ent cf. T rans¡:IOrtation.
The stann W2ier coUeCöon system fer Higtlway 50 ccileds runoff' from an area of
approximatsty 23 aa'eS. RI.I1Off1rorn' the 23 aaas is collected in storm water inlets and is
discharged 1hrough a rip-rap lined channel, directly intD Cenœr Lake- The remeining 60 aces
in the drainage bël.sin is' ccmprised, largely of residentiêi and some businesses. The s1Drm
water runcff'from this arsä is, collected through' a series of storm water ccØedion strud1Jres
, and eventually discharges tc the fake.
The waær'quality'in Cenœr'taœ has been a ma11er'~"increasing'concem fcr'1he' City'fer"
several years. It is' estimated "d1at 1he stcrm water" ccledibn system fer Highway 50
ccntibutes approximately 33 percent of aii 1I1e n.moff entering Center Lake. The runoff from
Highway 50 is heavily laden wätr debris and pollutants and enters Canter Lake wiihCut benefit
of 1Æatment. The resufting water quaJity in f1e lake ~ poor.
.
'The level of Center -Lake has' also been a matter at c:n;em fer 1he City during seven:! or
multiple storm events:EXœsSve rains cause ltTe lake tc overflow ante. west. A venue and
8ghth SIÆet In additiCX1, high waters threaten to flood a 'sewage lift s1ation on the snore at
Center Lake. '
Proposed Stonnw&ter Tœatment SoIuöon
PoliutEnt loadings to the lake can be reduced by C2pturing the runoff from Highway 50 and
diverting it 10 a retentimpa1dpropcsed on a parœl at land O'M"Jed by the Cïy. The retention
pond WIll be sized 10 capture the first flush at runoff frcm+tighway 50, thereby reducing the
majority of JX)tlutants errtråring the lake, The CRy has already, begm treatment at the quality
, of 'Mater in Center Lake by instaIJing native aquatic vegetation around 1he perimefsr-
The level in the lake cæ1 orUy be.' controlled by pumping' the water out at the drat ~, basin.
This will be accomplished by usi1g a combined eflbrt at Cèntinuous !eve ccnlrcl and' stann

Dear Mr. L'UIDbmi:
The foUowing is a summary ofthe"conslrUction plan modifications aDd ueaunent volumes associated with
c:ach p1an.
.
The origiDal plan c!esign concept approved by the LaJœ Coun¡y Waœr Authority was to provide for
a lift SlatÎOIlauc!. stormwaterpond at the City's 12" SueetrPark to treat 0.93 Ba'Cafect ofstormw&tcT
from a 12.62 acre drainage basin c1.I1'TC:ntly direcùy disçbarg,ing to Center Lake.
The new plan design provides for swales around 1he entire perimeter of the la]œ interCePÐns how
the StOmlwater pipes directly discharge intO Center Lake and the swales provide for 0.32 acre.feet
of 1reatØ1eJ1t and a wet detention area is proposed at me point of discharge from the F.D,O.T.
draiDagc basin. The: wet detention area provides for treatment volume of 0.46 açre~feet thus the total
treatment volume und.crmenew desi¡n is 0.7& acre-feet. Adc1itiouaJly. tbenew design provides for
iDœrception of soli~ sediments. oils. and greases for the entire c1raina.ge basin of 65.12 acres.
.
" LasdY. per our geoteclmical and enVÚ'Onmental evaluations. the estimarcdscasonal high water cable is at
c)evatÎ.œ 92.S to which the swales would remain city during a Donna1 rainfall year. PeT our phone
COIIvcrsation . Tamara llichaTdson is to supply you wi1h the freq~C)' of which the swales would be
inll1daœd or under MICr. 1 trust that WI information is sufficient for your needs. Should you have any
qucstiœ.s. please fee1 tree to contaCt me.

Dear Mr. Lwnbarcl:
.
Subsequent to our mco1Ü1g with you and Tamæa Richardson from the City of Clermont on Thursday,
November.20. 2003. we have modified theconstri1ction plans for the Center Lake project 10 eliminate the
stOmlwater pumpjng swion force main and perco1ation pond at Ù\e City Park.. The revised plans that you
received yesterday still include stonnWater quality improvements to the proposed 1m by eliminatin¡ direçt
discbalge to Center l.a]œ and constructing swales atoWld the perimeter ofthc lake which will settle heavy
solids ad metals and skim oils IDd greases. The swales will aJso reduce sedimc:ntation and siltation build
up, which bas been a problem iD the past. The sump area originally PJOPOsed to receive stormwater nmoff
Û'Om S.R. SO is still p1anned md win receive stOrmwater runoff. settle heavy metals, and solids in a wet
detendoD. capacity and skim oils and ¡:reases prior to discharge: to Ctntcr Lake. The water quaHty achieved
in m.: swalC$ as .çomparod to me WalCf Mana:ement District criteria ranges between 3% and 33% of the
wlume requiIed. However. the swales wil1 provide for 90-100% removal of solids. sands. and silts and oils
and ¡pases. The sediment sump for the discharge &om Highway SO provides for 96% of the volume
required. by me Waœr Management District as well as provides for seu1ement ofhcavy matcrialsþ silwþ and
sediment and skimming of oils and ¡reases.
Should you have any questions with ¡egards to this information. please feci free to contact Mc.

ATTACHMENT C
PUBUC BENERr
The, waœr quafity of Center- Lake is poor åue to the untreated scrmwater 1hat regularly
enters- the-lake. Center Lake is located on Cfty owned park. which ¡ndudes- a- fitness ÌlëliI,
and a picnic area. The area' is used heavily by Iccai residents fer pefSjoai rec-cëroCiì as
wetl as' public events, such as hoiiday c:;Jebrations. Although the lake is not considered
recreational wate."S", its appearance and, occasionally its' odor are a detriment 10 the
recreational uses of the surrounding property. in addition, there is some conœm. for
public health and safety created by the poor water quc¡tity at a lake freque.'1ted by 1tïe
public.
The treatment and level management provided by. the proposed improvements wiil
benefit the park through aesthetics and improved public heafth'and safety. In gene:a,I,
the City is a strong proponent of providing tÆatment at stormwater'prior to entering' any
natural b cdy at water'ancUunds projects: annuaßy to I t;tb uti t existing stDrmwater systems
whidl discharge directly irrlD natural, water ,bodies.
