RE: PEAK FLOW MANAGEMENT STUDY FOR WASTEWATER
Request: A RESOULUTION OF THE CITY COMMISSION OF THE CITY OF
OPA-LOCKA, FLORIDA, REQUESTING APPROVAL TO AUTHORIZE
THE CITY MANAGER TO ENTER INTO AN AGREEMENT WITH
FLORIDA INTERNATIONAL UNIVERSITY DEPARTMENT OF
ENVIRONMENTAL ENGINEERING (FIU) TO CONDUCT A PEAK
FLOW STUDY FOR THE CITY OF OPA-LOCKA SANITARY SEWER
SYSTEM IN THE AMOUNT NOT TO EXCEED TWENTY THOUSAND
($20,000.00)TO BE PAID FROM ACCOUNT NO.64-533312
Description: THE CITY OF OPA-LOCKA, IN ORDER TO COMPLY WITH TERMS OF
THE CONSENT AGREEMENT WITH MIAMI-DADE DERM FOR THE
UPGRADE OF ITS WASTEWTER INFRASTRUCTURE SYSTEM, MUST
COMPLETE AN INITIAL STUDY OF THE RAIN WATER'S E)~'1-ECT
(INFILTRATION AND INFLOW) INTO THE EXISTING SEWER PIPES.
THIS STUDY IS TIME SENSITIVE AND CAN ONLY BE PERFORMED
BETWEEN THE MONTHS OF MAY THROUGH OCTOBER (THE RAINY
SEASON). ADDITIONALLY, THIS STUDY IS NECESSARY TO ASSESS
POTENTIAL IMPACTS ON OTHER STATIONS SCHEDULED TO BE
IMPROVED THIS YEAR AND THE YEAR AFTER.
Financial Impact: Currently six (6) more stations (PS #1, 2, 5, 7 & 10) are in a state of
moratorium and are scheduled to be upgraded. The peak flow
management study will provide necessary data to properly rehabilitate
these stations. Any delay in moving with these projects will prevent
compliance with the terms of the consent agreement. In addition, these
1
improvements for the wastewater infrastructure improvements are
already accounted for in the current Budget FY 2009/2010 (page 185
project #23. 24, 26 & 27) and are expected to promote future economic
growth for the city.
Implementation Time Line: Immediately
Legislative History: None
Recommendation(s): Staff Recommends Approval
Analysis: Peak Flow Management Study (PEMS) is mandatory as one of the requirements
under the current consent agreement between the City of Opa-Locka and DERM.
The Peak Flow Management Study will require comprehensive measurements for
all the City's Stations. In consideration of the fact that Florida International
University (FIU) is a State University, they are uniquely qualified and could
assist the city in the design of the pump stations as well as creating opportunities
for interaction with the city.

Mr. Bryan Finnie
City Manager, City of Opa-Locka
780 Sharazad Blvd
Opa-Locka, FL 33054
RE: Extension Request for Sanitary Sewer Collection System Consent Agreement.
bear Mr. Finnie:
DERM is in receipt of Mr. Fernand Thony, PE's letter dated January 25, 2010, addressing issues
relating to the Consent.Agreement between the City and DERM concerning City's sanitary sewer
collection system. This consent Agreement was finalized on October 26, 2009. Two of the items
addressed in the Consent Agreement were the completion of Remedial Action Plans (RAP) for
those City pump stations that were in an unsatisfactory moratorium status (Paragraph 9, due on
2/23/2010), and providing a statement of the status of the Peak Flow Management Study (PFMS)
for the City's sanitary sewer collection system (Paragraph 11, due on 1/24/2010).
The requirement in the Consent Agreement was for the City to provide a RAP for all of the
stations that were in unsatisfactory moratorium status by February 26, 2010. The actual remedial
actions to bring all of the stations into compliance were required to be completed by December
31, 2014. The City has requested a variance to postpone the delivery of the RAPs for the stations
for at least six months until the PFMS for the City has been completed.
The requested extension is unacceptable to DERM, and failure to provide the RAPs as required in
the Consent Agreement will require DERM to invoke the penalty clauses of that agreement.
Pursuant to Section 24-42.3 (b)(ii), no municipality can issue building permits, and DERM cannot
release sewer certifications, until the corresponding utility has obtained a written approval for the
plans for the corrective actions designed to provide adequate transmission capacity.
The submittals of the RAPs for the stations currently under moratorium, in effect even before the
current Consent Agreement, are already overdue. Further delay to an uncertain date in the
future cannot be permitted. RAPs meeting existing requirements for those stations currently in
violation shall be provided by the due date in the Consent Agreement. Be reminded that,
updating a RAP in the future to meet changing system requirements is acceptable.
The requirement for the PFMS in the Consent Agreement was that the City provide a report on
the City's progress in the completion of the PFMS to DERM by January 26, 2010. The Consent
Agreement did not change the date when the City is required to provide the completed PFMS to
DERM. The required completion date, as previously notified to your municipality on letter dated
4/07/2009, is February 4, 2010.
Mr.Bryan Finnie
February 2,2010
Page 2 of 2
The information provided in the letter.from Mr. Fernand, dated January 25, 2010, satisfies the
requirements in the Consent Agreement with respect to the submittal of a Status Report for the
'PFMS. Please note that this does not relieve the City of the requirement to provide the completed
PFMS to DERM by February 4, 2010. If, as indicated in the letter, the City cannot meet this
requirement, you are urged to contact Mr. Joe Ramdial, Code Enforcement Officer-DERM, to seek
a modification to the Consent Agreement.
Please be aware that additional enforcement may follow if you fail to provide the PFMS by the
required date, which may include referring the City of Opa-Locka to the Violations of
Environmental Regulations at Government Facilities and Properties in Miami-Dade County, Florida,
Report.

Environmental Protection, hereby gives Notice of Permit Issuance to construct a domestic wastewater
collection/transmission system (FDEP Permit No. 253651-246-DWC, Permit Number 2010-SEW-EXT-00008)
to the applicant, MOHAMMAD ABU NASIR, CALVIN GIORDANO &ASSO. INC. The project is located at CITY

The applicant's mailing address is Attn: MOHAMMAD ABU NASIR, CALVIN GIORDANO & ASSO. INC., 1800

246-DWC, Permit Number 2010-SEW-EXT-00008) on this matter is available for public inspection by
contacting the Water& Wastewater Engineering Section at (786) 315-2800 and making an appointment to
view the files during normal business hours, 8:00 a.m. to 4:00 p.m., Monday through Friday, except legal
holidays, 11805 SW 26 Street, Suite 124, Miami, Florida 33175-2474.
A person whose substantial interests are affected by the above proposed agency action may petition for an
administrative determination (hearing) under sections 120.569 and 120.57 of the Florida Statutes. The
petition must contain the information set forth below and must be filed (received) in the Office of the
Miami-Dade County Attorney, 111 N.W. 1s`Street, Suite 2810, Miami, Florida 33128. Petitions filed by any
persons other than those entitled to written notice under section 120.60(3) of the Florida Statutes must be
filed within fourteen (14) days of publication of this notice or receipt of the written notice, whichever
occurs first. The petitioner shall mail a copy of the petition to the applicant at the address indicated above
at the time of filing. The failure of any person to file a petition within the appropriate time period shall
constitute a waiver of that person's right to request an administrative determination (hearing) under
sections 120.569 and 120.57 of the Florida Statutes, or to intervene in this proceeding and participate as a
party to it. Any subsequent intervention (in a proceeding initiated by another party) will be only at the
discretion of the presiding officer upon the filing of a motion in compliance with rule 28-106.205 of the
Florida Administrative Code.
A petition that disputes the material facts on which the Department's action is based must contain the
following information:
(a) The name, address, and telephone number of each petitioner, the applicant's name and
address, the Department File Number and the county in which the project is proposed;
(b) A statement of how and when each petitioner received notice of the Department's action or
proposed action;
(c) A statement of how each petitioner's substantial interests are affected by the Department's
action or proposed action;
(d) A statement of all material facts disputed by petitioner or a statement that there are no
disputed facts;
(e) A statement of facts which the petitioner contends warrant reversal or modification of the
Department's action or proposed action;
(f) A statement of which rules or statutes the petitioner contends require reversal or modification
of the Department's action or proposed action; and
(g) A statement of the relief sought by the petitioner, stating precisely the action the petitioner
wants the Department to take with respect to the Department's action or proposed action.
A petition that does not dispute the material facts on which the Department's action is based shall state
that no such facts are in dispute and otherwise shall contain the same information as set forth above, as
required by rule 28-106.301 of the Florida Administrative Code.
Because the administrative hearing process is designed to formulate final agency action, the filing of a
petition means that the Department's final action may be different from the position taken by it in this
notice. Persons whose substantial interests will be affected by any such final decision of the Department
have the right to petition to become a party to the proceeding, in accordance with the requirements set
forth above.
In accordance with Section 120.573, F.S., the Department advises that mediation is not available in this
case as an alternative to filing a petition for an administrative determination.

Peak Flow Management Study:
Reducing Peak Rainfall Derived
Infiltration/Inflow Rates
in the City of Opa-Locka
Project Infformation
I. Describe the project,its location,the scope,why it's needed and the
Environmental benefit
1.1 Statement of Problem:
Peak Flow Management Study(PEMS)is mandatory as one of the requirements under the current
consent agreement between the City of Opa-Locka and DERNI. The Peak Flow Management
Study will require comprehensive measurements for all the City's Stations.
Storm pipes are designed to convey rainwater and groundwater, while sanitary pipes are
designed to convey domestic wastewater, such as water from toilets, sinks, washing
machines and showers. If rainwater or groundwater enters the sanitary sewer system,it is
referred to as inflow and infiltration(I/I),respectively. When I/I is big, it consumes sewer
capacity needed for future growth in the region. Wet weather magnifies existing inflow
and infiltration sources. As a rain event begins the inflow and infiltration sources start
filling the sanitary sewer systems with clear water, eventually filling the sewer systems to
capacity. Once the sanitary sewer systems have reached capacity or becomes overloaded,
wastewater flows at much higher water level than normal and if sanitary fixtures or drains
are below this overload level, water will flow backward through the sanitary sewer pipe,
flooding basements or households and causing manholes to pop open releasing
wastewater onto the street. Sewer overflows are damaging to the environment and
sensitive ecosystems. When sewer overflows into private residences, buildings, parks,
and streets or waterways, potential health hazards arises, it contaminates all bodies of
water fed by the waterways and all creatures/plants coming in contact with the polluted
water. Sewer overflows also contribute to beach advisories and closures due to
contamination. Overflow occurrences put public health at risk and violate Florida State
environmental regulations. For this reason, the city of Opa-Locka fails to meet the state
guidelines and became ineligible for low interest loans from the Florida State Wastewater
Revolving Fund. As a result,the city has to reduce I/I to be eligible to apply construction
fund for the proposed wastewater treatment plant at a reasonable capacity of 3 MGD.
Since I/I significantly increase the amount of sanitary sewer flow rate, the corresponding
wastewater bills also increases with the I/I rate, because the city of Opa-Locka has to pay
WASA much higher wastewater price due to infiltration and inflow. Table 1 shows the
amount of wastewater treated during 1997 to 2006:

Figure 1: City of Opa-Locka Wastewater Treated from 1997—2006(Source: Miami-
Dade County Water and Sewer Department 2006 Comprehensive Annual Financial
Report)
This figure shows that the actual average wastewater flowrate for the city of Opa-Locka
is about 3.786 MGD (1,382 MGY/365 days) in 2006. The maximal wastewater flow rate
is in 2002, the wastewater flow rate is 2,287 MDY/365 days = 6.27 MGD. However, if
the infiltration is in the normal range of 40 gal/capital/day, the total dry-weather base
flow should be 120 gal/capita/day = [70 + 10 (commercial/small industrial flows) + 40
(UI)]. Figure 1 suggests a raising trend of wastewater treated per capita in GPCD from
200 to 250 during 2003 to 2006. Therefore, extra I/I increased from 67% in 2003 to
108% in 2006, which is extremely high compared with the base flow for dry weather of
120 GCPD. The city is clearly experiencing excessive infiltration/inflow. The major
reason for this high I/I rate is due to the old wastewater collecting system in the city. The
deteriorating sewer infrastructure could be leaky manholes, cracked pipes, improperly
connected storm drains and roof gutter downspouts. During the rainy season, the I/I
should be much higher than the dry season due to higher groundwater table and flooded
areas.
There are various costs associated with inflow and infiltration including sanitary sewer
system overflow, with wastewater treatment and transportation facilities. Overflow costs
are associated with road and waterway cleanup and the potential for fines if the overflow
problem is not corrected. Additionally, sewer system backups into basements or
households can result in litigation and potential liabilities for the responsible city or
agency. Eventually, new homes or businesses may not be allowed to connect to the
sanitary sewer system if the inflow and infiltration issues are not corrected, increasing
costs to residents as new sanitary sewer systems are installed or potentially lowering
housing values due to the inability to develop land for future growth.
Inflow and infiltration costs water treatment facilities and consumers large amounts of
money in water treatment operating expenses. All water entering a water treatment
facility must be treated as wastewater causing an increase in operating costs proportional
to the amount of clean water entering the sanitary sewer system due to inflow and
infiltration. During a rainstorm the load on the sewer systems can triple or more. Costs
associated with processing the added clean water from inflow and infiltration are
eventually passed back to the consumer in the form of rate increases. By reducing inflow
and infiltration capital and operating costs can be lowered. Minimizing inflow and
infiltration can also increase the lifetime-capacity of a treatment facility and wastewater
transportation system. The pumps that are involved with wastewater treatment and
transport operate 24 hours a day seven days a week; however they must work harder as
the sewer system's water level load increases. This puts an unneeded strain on the pumps
and shortens the life expectancy of these expensive pumps.
All of the above cost ultimately rested upon the citizens of Opa-Locka. As a result of
high I/I flow, the residents in the city of Opa-Locka are complaining to city officials
about the rising water bills. Recently, the city officials addressed the high rates by
encouraging water conservation. For example, the 2008 ordinance penalizes residents by
tripling rates when they consume more than 6,000 gallons a month. Rates climb even
steeper when water use reaches 12,001 gallons a month. The ordinance favors businesses.
because their rates are steady no matter how many gallons flow through commercial
meters. Since water and sewer rates are scheduled to be raised annually from Oct. 1, 2009
to 2012 by the Miami Dade WASAD, the city of Opa-Locka has to reduce I/I to lower
water bills for its citizen. This project is to remove excessive I/I and to reduce sanitary
sewer. A successful I/I removal program will significantly reduce the amount of the
City's payments to Miami-Dade County. After successfully tightening up the City's
sewer system, a request for inclusion for the construction of a 2 to 2.5 MGD treatment
plant will follow.
For water and wastewater service,the city of Opa-Locka is paying about$2,000,000 each
year to the Miami-Dade County Water and Sewer Department (WASD) in the past
twenty years. To reduce water bills, the City Opa-Locka Commissioners need to pass a
resolution by committing itself to reduce I/I flow so that its citizen will pay less water
bills. When the sewer system is first assessed, a comprehensive RDII project can be
implemented with this requested project. The target is to reduce I/I by 50% so that the
design flow rate of the treatment plant is at range of 3 MGD. As a result, the cost of the
plant can be reduced to $15 million by building a Wastewater Treatment Plant at the
city's abandoned Water Treatment Plant site. Depending upon available funds, the plant
could be further expanded to reclaiming treated wastewater for irrigation purpose.
Objectives:
To reduce I/I, the first step is to determine what are the major sources of I/I and where are
located. The usual problems for high I/I could be leaky manholes, bad connections,
cracked pipes, improperly connected storm drains and roof gutter downspouts. The
second step is to design a reduction plan so that the major I/I sources could be eliminated.
The third step is to implement the plan to achieve the reduction target of 70% of the
maximal I/I, which reduce I/I from 170 to 51 GPCD at the maximal rain event. As a
result, the average sever flow rate will be: 135 gal/capita/day = [70 + 10
(commercial/small industrial flows) + 51 (I/I)]. This flow is reasonable for a treatment
plant to be build at 135*15000*2=4.05 MGD as a design flow rate.
To effectively manage sanitary sewers, various I/I reduction strategies are available.
Public property I/I reduction strategies involve methods which reduce I/I into the
manholes, sewer mains and service laterals within the public rights-of-way. Private
property I/I reduction strategies involve methods to reduce I/I coming from the
homeowner's property. During dry weather the impact of inflow and infiltration can vary
from minimal impact to a significant portion of the sewer pipe flow.
This project is to reduce the maximal Inflow and Infiltration(I/I) for the city of Opa-
Locka from current 170 to 85 GPCD. The following are the objectives of this project:
1) To install monitoring instruments and conduct SSES:
a) Flow and rainfall monitoring.
b) Detailed data analysis of collected flow and rainfall data.
c) Identification of remediation projects.
d) Public communications program.
2) To design reduction plans so that the I/I could be effectively reduced by 50%
for a pilot scale and then the full scale in the city of Opa-Locka.
3) To implement the plan to reduce the major I/I sources and monitor the
success.
4) To full scale implement the reduction plan for the final 50%I/I reduction.
Implementation of this project will result in more secure and cost-effective wastewater
sewer systems that will meet the needs of current residents and future growth. This
project is the first step towards self resolution of wastewater problem for the city of Opa-
Locka by converting the abandoned water treatment plant into a wastewater treatment
plant.
Project Description:
To conduct I/I investigation, flow monitoring devices will be installed throughout the
major pump stations. The rainfall record and the groundwater levels will be collected to
carry out mass balance for each pump stations so that the major contribution of I/I will be
identified. For I/I field investigation, rain gages will be installed. Groundwater level
closing to manholes connecting of 10" sewer pipes will be monitored after mass balance
was carried out and major contribution of I/I locations were identified. The major
environmental benefits are reduction of I/I after infiltration is reduced by retrofitting the
manholes or sewer lines. Once the infiltration is reduced to the acceptable level, the city
proposed to convert the abandoned Water Treatment Plant into a Wastewater
Treatment/Reclaiming Plant.
L I/I Study
Generally speaking,the following methods can be used to conduct the I/I study:
1) Flow Monitoring
2) Field Investigations for Inflow sources.
3) Closed Circuit TV Inspection
4) Trunks
5) Laterals
6) Service Laterals
7) System Modeling
8) System Analysis and Work Prioritization
9) Cost Estimating of Reduction Program
In principle, the following instruments should be installed:
1) One flow meter for every 30,000—50,000 feet of sanitary sewer pipe
2) The flow meter recording should be set at 15-minute intervals
3) Flow meter capable of measuring surcharges
4) One rain gauge for every 2-4 flow meters
5) Minimum monitoring period—45 days with 60 days being optimal
6) Measurement of between 6-8 separate rainfall events
7) The system should be monitored during a period of high seasonal groundwater
Flow Monitoring — sewage flow rates are monitored at various locations within the
municipal sewage collection system. The flow data is analyzed, along with rainfall data,
to determine if there is excessive I&I within the study area.
Smoke Testing — a non-toxic, stainless, odourless, vegetable-based "smoke" is injected,
under pressure, into a sanitary sewer manhole. If smoke escapes from a source not
connected to the sanitary sewer system, this would indicate a sewer I&I cross-connection.
Dye Testing — non-toxic dye is added to an upstream freshwater source believed to be
contributing to I&I. The downstream sanitary sewer is then monitored for traces of the
dye to confirm the existence of a sewer cross-connection.
Closed Circuit Television Inspections — a video camera is sent through a sewer line to
record the condition of the sewer. The video footage is analyzed for cracks, intrusions
and leaks.
Inspections—building inspectors and trained maintenance personnel visually inspect and
assess the condition of the sewer system. The costs of managing excessive I/I
Costs to store and treat excessive I/I were estimated, as were costs to reduce I/I at the
community level. Several key assumptions are needed to estimate these costs until more
information is available. These assumptions are as follows:
1)Excessive I/I that causes peak flows to exceed the basis of design of the interceptor
system would be stored underground at each point of connection to the interceptor system
rather than conveyed in larger sewers and pump stations.
2) The primary impact of high levels of I/I at the treatment plants is the increase of the
monthly average flow. Within the MDS, the peak monthly I/I flows are usually to be
about 30 gallons per capita per day(gpcd). For purposes of estimating the cost of treating
excessive I/I, monthly I/I flows exceeding 30 gpcd are deemed excessive.
3)The capital cost of treating I/I is estimated at$2 to $3 per gallon per day (gpd),based
on actual costs of$3.50 to $5.00/gpd for their treatment, and estimating that 40%of the
cost is associated with solids management and the strength of the wastewater.

The cost to eliminate I/I from a foundation drain can range from several hundred dollars
(disconnect the discharge from the sump pump)to $8,000 for installing a new outside
sump pump, curb side receiver, and yard restoration. The average cost of$3,000 is
assumed for eliminating I/I from private property. The peak hour flow for a 25-year rain
event will be simulated using a hydraulic model calibrated with sewer meter data.
Excessive peak hour I/I is estimated at 4 mgd,which is equivalent to 3000 gpm. If each
connection is contributing 8 gpm to the peak hour flow,there would be about 400
connections to repair. At a cost of$3,000 per connection,the cost to eliminate the I/I at
the source could be$1.2 million.
Time Schedule:
August, 2010: Conduct Sewer System Evaluation Survey(SSES)
September, 2010: Pre-design and final design for the selected initial I/I reduction
projects.
October,2010: Construct the initial I/I reduction projects.
October, 2010: Complete review of project results to construct all the I/I reduction
projects to achieve I/I reduction of 50%for the city of Opa-Locka.
Tasks:
Task 1: To isolate candidate dry days to serve as basis of dry —whether diurnal flow
curve, antecedent precipitation intensity and duration will be analyzed. Dry day flow
curves for both weekdays and weekend days will be developed based upon hourly
average flows for all dry days in the monitoring period. Flow rate(MGD) vs. hour for all
dry day curves and average curve for both weekdays and weekend days for each
monitoring sites will be constructed.
Task 2: For each defined storm, rainfall intensity, duration, frequency (IDF) will b e
analyzed. Actual storms' IDF against standard storms of return with frequencies of 1 to
100 years will be plotted. Rainfall hyetograph, hydrograph trace, dry day average trace
for weekday and weekend will be derived by analyzing hydrographs of Q vs. day and
hour for each defined storm for each sub-sewershed. As a result, Rainfall-derived
infiltration (RDII) will be quantified. For each observed storm, RDII will be calculated
for both peak rates and total volumes. The final results of RDII will be presented in a
table reflecting rainfall peak and average rates and volumes, time to peak, peak flow and
I/I values, and daily gross and net flow and I/I volumes for the 24-hour rain day and
subsequent recovery day periods. All of the results will be displayed on storm analysis
hydrographs.
Task 3: The rainfall volumes, rates, the peak flow, and total volume data in the storm
analysis will be used for RDII analysis. Volume of RDII (MGD) will be plotted against
rainfall (inches) for each gross and net sewershed. In the basic and extended monitoring
period, the RDII vs. date will be plotted for each storm. The major outliners will be
indentified. Linear regression for selected storms will be shown on the RDII plots.
Task 4: For each defined storm, RDII severity will be ranked.for each defined storm. The
severity will be normalized against sub-sewershed pipeline tributary length or area. The
projected sub-sewershed for design storm of 2, 5, 10, and 20 years will be calculated.
Task 5: Based upon RDII characterization and severity, Sewer System Evaluation
Survey (SSES) activities will be recommended to achieve minimal 50% PI reduction. A
plan will be developed for analyzing effectiveness and rehabilitation using quantitative
data. Analytical procedure for relative severity of the RDII in each sub-sewershed before
and after rehabilitation will be developed.
After the SSES, the following techniques will be used to reduce and eliminate sources of
I&I:
1) Replacing or rehabilitating the defective sewer pipe, sewer connections, lateral
and/or manhole(30%)
2) Disconnecting known inflow sources, such as cross-connected catch basin drains,
footing drains or rainwater leaders (15%).
3) Pipe grouting—using a cement-based grout to fill a hole or crack in a pipe or
manhole (10%)
4) Pipe relining—inserting a flexible liner into a defective sewer pipe or sewer
service lateral which hardens into an impervious surface(5%).
5) Installing drainage systems that will allow cross-connected sewers to be separated
(5%).
Cost Saving
The first phase will reduce 20% of the PI by retrofitting the main connections and
manholes which were found to be major contributors to the I/I flow. Once the reduction
techniqes are validated, a further 50% PI reduction will bring the peak flow down to 5
MGD. Other percentage reduction are listed as above. As a result, the total I/I flow
reduction will be 50%, the peak flow rate would then be 5 MGD. As a result, the citizen
of the City of Opa-Locka will pay less than 1/2 of their current water bills. If the charge
to the citizens remain the same, the saving can be used for further I/I reduction until the
goal of 70%I/I reduction is reached.

2.2.Demographics
As of the census 2000, there were 14,951 people, 4,890 households, and 3,437 families
residing in the city. The population density was 1,333.2/krn2 (3,451.9/mi2). There were
5,407 housing units at an average density of 482.1/km2 (1,248.4/mi2). The racial makeup
of the city was 22.83% White (3.1% Non-Hispanic Whites,) 69.64% Black or African
American, 0.35% Native American, 0.21% Asian, 0.02% Pacific Islander, 3.60% from
other races, and 3.35% from two or more races. Hispanic or Latino of any race was
28.55%of the population.
2.3 Hydrologic Characteristics
City of Opa-Locka locates within the region of the "Biscayne Aquifer", named after
Biscay Bay, which is a surfacial aquifer. It is a shallow layer of highly permeable
limestone under a portion of South Florida. The area covers a total amount of 4000
square miles including Broward County, Miami-Dade County, Monroe County, and
Palm Beach County.

Figure 3: Biscayne Aquifer as shown in Florida Map
With respect to the hydro-geologic characteristics, the Biscayne aquifer consists of highly
permeable limestone and less-permeable sandstone and sand. Most of the geologic
formations comprising the aquifer are of Pleistocene age but, locally, Pliocene rocks also
are included in the aquifer.
2A Hydrologic Systems
Ground water and surface water form an integrated hydrologic system in southern
Florida. Before development of these water resources, a large proportion of the abundant
precipitation that fell on the flat, low-lying area drained southward to the Gulf of Mexico
and Florida Bay. Most of this drainage was in the form of wide, shallow sheets of water
that moved sluggishly southward during the wet season, when as much as 90 percent of
areas, such as the Everglades, was inundated. This drainage was the major source of
recharge to the underlying aquifers. During the dry season,water moved only through the
deeper sloughs and covered probably less than 10 percent of the Everglades. Lake
Okeechobee, the second largest freshwater lake wholly within the Continental United
States, was a major water-storage component in the system, functioning as a retarding
basin for streams, such as the Kissimmee River, that drained southward into the lake.
Today, the shallow, southward-moving sheet of surface water still is a major source of
recharge to the Biscayne aquifer in addition to the precipitation that falls directly on the
aquifer. Where the Biscayne is either exposed at the land surface or is covered only by a
0 '44100

Figure 4: Current Land Use Pattern for the City of Opa-Locka
The City of Opa- locka is home to Opa- Locka Executive Airport and is located in close
proximity to the North Campus of Miami-Dade College. Services to the College are
already provided by the City, so the benefit would be ideological as a point of reference,
as opposed to financial. In order to optimize the use of these resources, the City proposes
to annex additional land to expand its borders and acquire property in the area. The
proposed annexation areas are designated for commercial and industrial purposes so the
City can increase tax revenues by placing impact fees for development as the
opportunities arise and the implementation of code enforcements and fines which will not
allow liens to expire after two years. The current land use pattern is showed in the
following Figure 4.
2.6 Project Location
The proposed site to build the wastewater treatment plant is located at the city of Opa-
Locka, Florida 33054, as shown in Figure 10. The site is bounded on the east by N. W.
154th Street' 17th Avenue, on the south by N.W. 119th Street,and on the west by N.W. 57th
Avenue. This location is occupied by an old water treatment plant which was closed in
1985 after the operation design lifetime of the plant had expired. The following photo
shows the current status of the site:
III. Census tract numbers of the existing and proposed service area.
3.1 Population Changes:
According to the 2000 Census, the City of Opa - locka has a population of 14,951
residents. The 1995 First Cycle Evaluation and Appraisal Report anticipated the
population would increase to 15,878 by 2000, reaching build out. The previous notions
were based on the immigration influx in Miami-Dade County, favorable climate,
economic opportunities,and a multinational culture to ease assimilation into the area. The
1995 EAR also suggested growth will continue based on the City's ability to: maintain
the level of service for infrastructure, successfully deter crime, and enhance the overall
quality of life. Despite these favorable projections, the City witnessed a two percent
population decrease since 1990, at which time the City reported 15,259 residents. Despite
the apparent decrease in population, which can be seen in Table 2, the Shimberg Center
claims this decline will be temporary as the population is expected to steadily increase
through 2025. Due to apparent fluctuations in the estimated and actual population within
the City, the EAR will utilize the 2005 projection by the Shimberg Center of 15,579 to
determine level of service (LOS) standards throughout the City,
3>2 Population Projections
Population projections from the Shimberg Center indicate that the City will grow by 8.26
percent from 2005 to 2025. The projections are based on the assumption that the current
demographic and development patterns will remain constant. Since there is actually a
decrease in population growth, the values may be overestimated compared to the trends
experienced throughout the County.
