Man-made Drainage Systems
Major st]dace drainage modifications to St. Lucie County .commenced with .the formation of the..
North St. Lucie River Water ConSol .District (1917) ~d the Ft. Pierce Farms Water Control District-
(1919), 'These Districts were created for the purpose of agricultural .drainage and irrigation, with a
secondary purpose being flood' control activities.
During the 1940's the US Army Corps :of Engineers (COE) channelized portions .of the North Fork-
of the St. Lucie ~ver in an effort to improve its water cma'ying capacity and to accelerate its'speed
of discharge into the .Atlantic Ocean. During the 1960 , the COE constructed Canals C-23, C-24,
and C-25, along with their control structures. With the construction of'this Primary.. Canal system
for the South Florida. Water Management District, the .County was then divided into a series of
SUb-Basins. Figures 6-C-1 through 6-C-5, beginning on page 6-C-3, indicate these basins.
The C-25 Basin, (Figure 6,C-6, found on page 6-C-8) is located in northwestern St. Lucie County
and extends into parts of Okeechobee and Indian River COunty's. This area is dominated .by
agricultural uses consisting of either citrus .or ranching activities. The canal system in this area was
designed to support agricultural activities. Although not the case in St. Lucie County, the -western
portions of this overall basin do not have any significant floOd control protection, which could in
times .of extreme rainfall'have detrimental effects in the downstream areas. With-the absence of any
signif'lcant urban development, local flooding is not presently a major problem in that on-site design
requirements meet the.current need. However, as elaborated further.in this element there .is a need
for a County-Wide review of this communities furore drainage management requirements and this
review will have to include the portions of'.this that lie outside~ of the County.
The C'24 Basin, (Figure 6-C-7, found on page 6-C-9) is located in the Central and
portions of the County. This basin may further be divided into three subgroups
(east 1/3), citrus (central 1/3) and ranching ( west 1/3). One of the primary purposes of
is to regulate the level of ground water, through the controlling effects of the S-49 structure
prevent the'intrusion of saltwater into the local groundwater Figure 6-C-1 - C-25 Basin- _

agricultural purposes, although, its eastern edges face the potential impacts of future urban
development. These emerging areas will.have to be:accommodated for through the~development of
interlocal, agreements between all effected parties addressing the-issue 'of urban discharge.
The North Fork of the St. Lucie ~River Drainage Basin, (Figure 6-C-9, found on page-6-C-12) is
located in the .most populOus part of St. Lucie County. This drainage basin includes within itthe
NOrth St. Lucie River Water Control District, along with portions of the City of Port St. Lu¢ie. ~As -
. 4 '
mentioned previoUsly, in the 19 0 s the ~n river course-was channelized by the Corp of Engineers.
This channelization was effective in increasing the rate of water removal from-the basin, but it also
allowed for the increased collection and transmission of silt and other debris, affecti'.f~g not only the
long term carrying capacity of the North Fork itself, but alSo contributing to the accelerated siltation
of the lower reaches of the St. Lu¢ie River.
The North Fork basin can be characterized as dominated by urban uses. What agricultural activities
remain are in the western reaches of the'district. However, it should be noted that although .the basin
serves an urban environment, the drainage designof this basin.is based upon agricultural needs. This
area has been the focus of several studies, evaluations and demonstration prOjects in recent years
attempting' to improve upon its overall efficiency. As discussed later in this element, these efforts
need to be continued and expanded.
The Taylor Creek-Nubbins Slough (C-59 Basin), (Figure 6-C-10, found on page 6-C-13)-basin
area is located in extreme southwestern St. Lu¢ie County. This basin affects only 9.5 square miles
of the County. Activities in this area are either ranching or undeveloped/vacant. There is effectively
no impact upon the balance of the County by this basin since its flows are to the west and the Lake
Okeechobee area. However, as addressed'in the goals, objectives .and policies portion of this element
attention to this area is needed on water quality issues.
Except fbr those efforts in Ft. Pierce and Port St. Lucie, almOst all of the surface drainage
modifications that have taken place have been designed for agricultural land uses, or approximately
a-10-year-24-hour storm event. As these agricultural lands have become more~urbanized, the
volumes of sto~water have increased and Figure 6-C-8 -C-23 Basin details

There are two disfinct .. Sources of groundwater in St' Lucie County: the shallow unconfined or
semi-confin~ aquifer, and the deep artesian floridan aquifer. These aquifer systems .are separated
bYa layer of relatively impermeable green clay known as the Hawthorne Formation, w~ch is about
400 feet thick and staas-at approximately 150-180 feet below the average land surface.
..
The shallow aquifer system is comprised of one (1) to five (5) feet of fine-grained sands and silts of
the Pamlico Sand that overlie the Anastasia Formation. The Anastasia Formation consists of'
interbedded layers and lenses of sand, shell.b~, sandy limestone, and sandstone. Beds and lenses
tend to be elongated in a direction that parallels the coast. Most~of. the permeable zones, which are
primarily shell beds, are thin and, as.a result, well yields are low to moderate. (USi3S, 1972.)
Water quality: is variable in'the shallow aquifer due m natural and artificial causes. Water quality
ranges from fair in the Southeast mainland part of the County to brackish in the .northwestern part
of the County. Thepoorer water quality 'has been associated with the use of the brachsh artesian
aquifer for ~gation of citrus. However, :drilling records and well water analysis indicate that there
Lu
is also an area of connate saltwater that extends from the vicinity of St. cie Village to thenorthem
and eastern shores of Lake OkeeChobee. The concentration of minerals in the connate water
increases with depth to"'.the base of the shallow aquifer and at that point it exceeds the mineral
content of the artesian aquifer.
The artesian aquifer system is part of an extensive carbonate rock aquifer system that .underlies most
of Florida. In St. Lucie County, the artesian floridan aquifer has three distinct producing zones of
different hydrologic properties and 'water quality separated by semi-permeable zones. The upper
producing zone, or Zone I, has the best water quality, but it is too brackish for domestic or public
water supply. The ~water from Zone I is suitable for stock watering and some crops, most notably
citrus. Most of the estimated 1300 artesian wells in the' County are developed in Zone I of the
floridan aquifer. There is no natural groundwater recharge to the floridan aquifer in St. Lucie
County. Producing zones, water quality, and Other technical data are more extensively described in

The diStance between water'level contours, when matched with the hydraulic gradient of topographic
relief, indicates the relative.permeability of the sufficial aquifer: the greater the distance between
contours, the lfigher the permeability. This is exemplified in the area bounded by SFWMD C-23 and
C-24 canals, where the land surface .has little relief and the water level contours are ~les apart.
Many secondary drainage.systems have been constructed for agricultural drainage. However, most
of these secondary systems are shallow and their impacts on groundwater are by way of preventing
ponding.
,~.
Because of the lack of recharge and the low permeability of the soils, the shallow aquifer provides
insufficient water for irrigation during the extended dry season. SFWMD Canals C-23, C- 24, and
C-25 serve .as linear storage reservoirs and provide irrigation supply for many areas although in
extreme periods of drought, they too may only be used in a minimal capacity due to the Figure

General
On the average, St. Lucie County receives about 53 inches of rain per year, most falling during the
period form June m October. It is recognized that from time to time, portions of thenty will
experience flooding problems as a result of heavy rainfall. Much of thelocal flooding that occurs
can be attributed t0~ development carried out before the advent 'of' contemporary stormwater
management', practices~. Most of :ttiedrainage: prOblem areas are located in the 'North Fork Drainage

The lack of a comprehensive drainage program for the County, particularly the eastern urban regions,
is emerging 'as an issue that.if left unaddressed, will significantly, and detrimentally, effect the
quality .of life for both existing and. futUre residents. As an objective of this element, St. LuCie
~ounty should embark upon a program to develop and implement a County_wide maSter stormwater
management program designed to address existing probleths and to avoid furore problems.
Aquatic Preserves
From a point just north of West Midway Road the North Fork of the St. Lucie River has been .
designated by the State of Florida as an Aquatic Preserve, Chap. 258.59(12), F.S., (Figure 6-C-16,
found on page 6-C-26). With the Aquatic Preserve designation these waters also carry the
classification of Outstanding Florida Waters. With the exception of the Northwest Fork of the
Loxahatchee River, no other fiver in this region has as much of its floodplain within such a
designated area. The combination of subtropical climate, unusual vegetation mixture, and wilderness
qualities in the midst of a major emerging urban area make this preserve distinctive.
_
. .
.
The Florida Department of Natural Resources has prepared a Resource Management Plan for this
area. This plan Was adopted by the State in May of 1984. This plan contains programs oriented to .....
the enhancement of water quality. The Aquatic Preserve Management Plan. prePared by the FDNR
~ncludes major program policy directives that describe the maintenance of water quality. This plan,
though noble in its goals, may be in conflict with some of the objectives of the small water
management and control districts that discharge to the North Fork of tt~e St. Lucie River. The areas
of greatest, conflict are relative to the design of the local drainage systems which utilize the North

problems in many areas~ ,of ,the County. The apparent causes for, many of
inadequate conveyance systems; pump'ed drainage at the upstream reaches of Creeks
urbanization; and inadequate floodplain planning.
These apparent problems may have different causes.' Inadequate conVeyance can be-caUsed bY?
overgrowth .of canals/ditChes, inadequate canal depths an~or cross-sections or shoaling from
sedimentation, as. ~.the No~h Fork of the St. Lucie River. In addition, pump~ dr~nage from farms,`
can drastically sho~en concentration times and may .surch~ge the receiVing ~ainageway, Also,
urba~Zation increases.mn-off and:decreases concentration times. In general, floodpl~n pl~ng -has
not kept pace with the changes in hydrology in St. Lucie County.
SFWMD design standard for urban areas is presently a three day/25-year.storm.
The isohye~ mapS found in Appendix A, show the rainfall.amounts and special variation of rainfall
in .the Coun~ for the above-referenced storm events. For the area immediately west of the Turnpike,
this difference be~een design storm events is.an additional four inches of rainfall in' the Urban area.
Therefore, the newer urban drainage'systems discharging to the older Primar~ drainage systems may
not function properly 'unless retention and/or detention is provided in the urban design or the primary
system is upgraded.' Consequently,. : development, projected in the Future Land Use Elements of the
County and the municip~fies needs to be used as a data source for
stormwater management plan.
Agricultural drainage of marshes and wetlands has removed the stormwater storage capacity of these
areas and thereby has added'to'the:overall volume ofstormwater discharged through the urbanized
areas. ~Concurrently, removal of this storage capacity has removed the major sources of groundwater
recharge with a resultant increase in dry season irrigation demand.. ~
..~
Surface water quality in the modified natural systems has been acceptable, but there is little data
concerning flood flows. Man-made drainage systems contain nutrients from agricultural and urban
mn-off as documented by the SFWMD. (SFWMD, 1988b) Canal C-25 has seasonal high levels of
dissolved minerals from floridan aquifer irrigation return flows. The issue in this regard is that this
canal serves~ as a recharge soume forone of the City of Ft. Pierce's primary wellfields.
Groundwater Systems: Abandoned free'flowing or Icing artesian wells are a soume of
contamination for the shallow aquifer, To abate this problem, St. Lucie County, in a cooperative
effort with the SFWMD, is engaged in a program to plUg these free-flowing or'damaged wells.
Deeper zone's of the floridan aquifer have .cavernous regions, or boulder zones of extremely high
transmissivities that are generally considered suitable for deep well injection of domestic secondary

A supply of fresh water, for irrigation and aquifer recharge is needed to replace the brackish water
presently being withdrawn from the floridan aquifer, Continued use of the floridan aquifer will
mineralize the shallow aquifer to the extent that agricultural productivity will decline and the City
of Ft. Pierce wellfield .along the C-25 Canal may not be usable. The SFWMD needs to assess the
impact of irrigation return .flows as part. of the well permitting process.
The proposed .S~D Taylor Creek,Nubbin Slough Diversion Project (formerly the C-131
Flow-way Project) may be a viable means of providing the needed water supply. Locating. this
p ojects storage reservoirs in St. Lucie County would provide a groundwater recharge source that
would help to displace mineralized groundwater..Since increased freshwater discharges into the
Indian River Lagoon via the'C-25 Canal have o e ' ......
~ ~ p t ntml negative ~mpacts, cons~dera[ion should be
given to the posSibility of "pulsing" releases of drainage from this canal into the Lagoffn, in 'the .same
manner as has 'been done successfully for the St. Lucie Canal by the South' Florida Water
Management District. By doing ~s, natural freshwater releases are more closely mimicked. Another
possibility to be considered in order to avoid detrimental impacts to the Lagoon from C-25 drainage
is the timing of drainage releases coincidentally with the outgoing fides of: the Ft. Pierce Inlet.
The 'u~e of treamd dOmestic Wastewater effluent to supplement irrigation supplies and recharge the
.shallow aquifer'Should be further investigated. The seasonal irrigation requirements necessitate the
use of storage or disposal of unneeded effluent. However, facilities using deep well injection for
effluent disposal are, in fact, storing the effluent and a significant portion of the effluent could be
recovered for irrigation use.
Inaddition to conserving the'use of groundwater by using i~gation 'quality (IQ) sewage effluent or
"surfaCe water.supplies, aquifer recharge through stormwater retentiOn and/or detention needs to be
considered for both area-wide and individual project applications. Retention by impoundment may
be used for furore iffigation needs by agricultural facilities and retention lakes in urban areas will
reduce the Volume of stormwater mn-off.

St. Lucie County has been operatin9 its present landfill since
19~8. In ~ i~!~i~, the County retained the firm of ~~=~,
Management ~g~~ Plan which was delivered in Dece~er,~
This plan ............ ~:~:~ ........................ Used extensively for the preparation of
sub-element. An additional report used was a .. Build-Out Plan
prepared Dy Camp, Dresser & ~cKee, Guly 21,
It should be pointed out that the ~ ~i~i management plan was
based on medium ~rowth projections as prepared by the Bureau of
Economic and Business Research (BEBR) at the University of Florida,
while for the purposes of the Comprehensive Plan, a high population
projection was selected by the County and approved by the
Department of Community Affairs (DCA) in ~ ~~!. For the
purpose of this sub-element, the basic direction, as determined by
the Solid Waste Management Plan, has been used as a ~iven with a
high population projection added to tabular data and a section
developed for the Solid Waste Management and Volume Reduction Act
of 1988. Care also must be taken in preparation of bond reports and
Other fiscal documents that the correct projections are utilized.

The primary focus of this element is to identify the facilities and
management pl.ans which the County will need in order-to manage and
dispose of the solid and ~~~ hazardous wastes ~enerated in
the County. For solid wastes, these include recyclin~ pro~rams,
transfer stations, processing- plan-~, and landfills. For ~
hazardous waste only transfer stations will be addressed since
disposal of such~ wastes within solid waste landfills is not
permitted in Florida by Section 403.722, F.S.
The term "landfill,, refers to the final disposal site of solid
wastes, and as it implies, involves burial of the wastes.
Landfills are classified for regulatory purposes accordin~ to the
characteristics of the wastes they are permitted to receive (DCA
Model Element, 1987) . '
Regulatory Framework
The potential environmental impacts of solid waste facilities have
led to the development of an extensive network of permittin~
requirements at the federal and state levels. Impacts on air and
water quality are reviewed by the U.S. Environmental Protection
A~ency (EPA) and the-Florida Department of Environmental Req~lat~--
-t~~®~~~im~~?~!~~!~i)il, and where dredging and filling might occur,
by the U.S. Army Corps of Engineers (CEE). The South Florida Water
Management District (SFWMD) also provides state level review of
stormwater quality and quantity impacts through their permitting
and regulation processes. Actual construction and operation of
solid waste facilities requires further permits and review by ~

or require tall emission stacks, further ~i~ ~ and Federal
Aviation Administration (FAA) review may .......... ~ ......... required. These

facility needs assessments, and site selection for hazardous waste
management f~acilities at the County, regional, and state levels.

Groundwater
Most of ~South Florida has a shallow depth to groundwater. In.St.
Lucie~.County, the.'Atlantic Coastal Ridge is the only exception to
this. Trench t~e landfills, where a trench is excavated-, filled
with solid waste and ithen covered with the excavated borrow
material, are nO!~ lo.nger permitted in South Flori!da ~because the
solid'waste can iget int° the groundwater and poll~ute'~it.
The polluted groundwater can traVel considerable dis~ nce and pose
as a significant health risk if used as a potable water-supply.
Area type iandfi where solid waste is piled on~.the %~and.surface
and then covered soil also produce ~a polluted leacha!te from
rainfall that even' lly percolates into the shallow fer if not
lined with an impe ~surface. Groundwater charact and
protection are
elements in the ~~i~ ~ s d waste
permitting process. Leachate cOllection a~ ............. ~"~eatment rems are
now a mandatory part of the engineering design in order prevent
the leachate from contaminating the groundwater. C. re of a
landfill cell includes a cover of Iow permeability to~ or
eliminate the leachate that will be generated.
Surface Water
The surface water at landfill sites occurs from rainfall and in
deep borrow pits. There is stormwater run-off from closed landfill
cells, roadways, parking areas and soil stockpile areas that is
usually routed through a ponded borrow pit for primary
sedimentation control. However, there is a potential for other
contaminants to be conveyed with the stormwater. Although a
portion of the stormwater may be detained on-site, storm events
that exceed the on-site storage capacity will discharge off-site
and may adversely affect the receiving body of water (RBW). The
treatment standards for the stormwater discharge are governed by
the SPWMD classification of the RBW.
Natural Resources
The n'umerous monitoring wells at the landfill site have not
indicated any contaminated plumes. The ~ drainage district
canal~- (96, ~u~ ~= u~) ~ is sampled and checked for
contamination.

Phase II DeVelopment: Phase Iii development includes two sub-
phases identified as II-A and II-B each occupying approximately
one-half of the Phase II area.
Major differences in development of Phase II as compared to Phase
I is the use of perforated rigid PVC pipe under drains for the
leachate collection system rather than flexible polyethylene pipe,
and the installation of a 60 mil thickness synthetic liner below
the leachate underdrain system rather than use of in-place soil
(o=z~=~, ~on~, ~~ ~==z~o~, -,,~.,, ~86). The Phase cell has a 40

Hazardous and Infectious Wastes
Currently, there is no regular hazardous waste separation,
collection, and'~removal program in St. Lucie County. The Glades
Road Landfill does ,not permit hazardous waste to be disposed of on
site and there is no other central collection point for this type
of'~waste. Infectious'waste as generated by hospitals, is disposed
of by by the generator:, or taken t,o an approved

POTABLE WATER SUB-ELEMENT
DATA &-ANALYSIS
I'NTRODUCTION
The Potable~ Water Sub.Element provides a~summary of existing potable .water supplies and
treatment facilities in St. LUcie COUnty. The~ facilities include, mUniciPal regional' ~s~~ms a~nd
.area, or .prOject, Specific systems, .in .addition;~0 s stems for individUral residence
The needs, for the. ,oun~ s future are d~scussed, ~with'goals, objectives, and policies focusing on
speCific activities which-will remedy those needs.
BACKGROUND
Terms and Concepts
A potable water suPply'system .normally consists of a water supply sou.me, a troatment, plant, and
a distribution and storage ~network. Either surface water, .stored in natural lakes or man-made
available and the cost of developing the soume for use.
Before being used.for public consumption, all water must be treated. Treatment removes impurities
from the raw water in order to improve, its quality for either 'public health or aestheticreasons, or
both.. The treatment process adds to--thecost of supplying.water, but it also expands.the range of
raw water sourness that can be .utilized.
After treatment, the water is supPlied to individual usem ina community by way of a network of
.pipes and.storage imserV°im. Large tranSmission lines, called distributi°n mains, carry~ water to
major ~demand areas and interconnect with a network of smaller lines which eventually supply
individual establishments. 'Both the distribution mains and distribution network should be
intemonnected to form flow loops to allOw water to cimulate from various portions ~of the system to
areas of highest ~mom.entary ~demand.

Water Supply Wells
The majodty of the water supply wells in St. Lucie County draw water from the shallow groundwater
aquifer roferrod'to as the surficiai aquifer. The wells located in this aquifer range in size from 1
inch, for the Iow demand systems, such as. a home or small business, to 10 inches for the larger
demand rogional systems. Also in $orvi¢o in the County are deep wells which are fed from the

Wastewater :treatment systems'occur.in many ~different rtyPes. They m

stations,, regional treatment plants, and effluent disposal facilities.
Regional Facilities:

The collection .system is composed of a network of gravity,se-wer
individual~ soumes and convey it to a central location for treatment. Fi~

Regulatory Framework
The Fedeml'WaterPollutio. n Control. Act (pLr,92-500)is the controlling.national legislation relating
to the .provision :of sanita~ sewer service., The goal of ,this .act is the restoration and/or
maintenance of the chemical, ~Physical~and ,biological integrity of .the nation's waters. The act
established the national ~policy :of implementing area-wide 'waste treatment and management
pro,grams to ensure adequate control of courses of pollUtants. Under Section 201 of PI 92'500,
gmntsare made available to-local governments to construct facilities to treat "point soumes" of
pollution, which include effluent from sewage treatment processes. The U.S. Environmental
Protection-Agency iS responsible for imPlementing :the act.

The Florida Depa~ment of Health and Rehabilitation Services (HRS) regulates septic tank and

_.
Individual septic, tanks are permitted by-the County Health Department and regulated in accordance
with Chapter 10D-6, F.A.C. When a privately or .municipally owned utility serves a community and
Charges on an individual basis, it is regulated by an overseeing Commission or Authority. Until
recently, this body was the Public Service Commission. Recently, the St. Lucie County Water and
