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.

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. • If you have any questions about the above, please have staff of the City contact Mr. Agustin Socarras, P.E., (786) 315-2800, or via e-mail at socara@miamidade.gov Sincerely, Imo! arlos Hernandez, .E.

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.

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: Table 1: City of Opa-Locka Wastewater Treated 1997-2006 • Wistc Year I realct1 (ia11t1ns per ('apita (iP('/1) 1997 1,121,000,000 77585 212 1998 783,000,000 53725 147 1999 711,000,000 48368 132 2000 706,000,000 47621 130 2001 1,101,000,000 73641 202 2002 2,287,000,000 151692 415 2003 1,135,000,000 74660 204 2004 1,204,000,000 78550 215 2005 1,267,000,000 81988 224 2006 1,382,000,000 88709 243 City of Opa Locka Wastewter Treated 1997.2006 450 i 400- • 350 I 0 t0- 300 i _. o 250 a' 200 1 — ..... .. -., __ • 150 _._- m t7 100 50 0 — — —--- 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 Year 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. Cost for I/I Reduction The cost to repair a leaky manhole is based upon the commercial products available as follows: Table 2: Cost to Repair a Leaky Manhole 0 A 1`water war !nnow per hour Total manholes Nunlaer or mandrel Tolel lnllow• 2 Manhole Corers pet ntanhve(Qpm} In eyelem affected(311) per hour 2 Mtn no pIc4 holes rza h f0} rte4 x 04) 4. 1!;pr VVcty e0 2 2000,.; 722 $10°Cp E Inches or Eat.Hours of Total Int low Treatment Coat Treatment Costs 7 prectphatioa 1 yr. precipitation r yr. par year per 1000 gauche per year NtatIonat avers r el i natIonat evere.el (E4 x t391 1£4_DS x 1000) :r ?: 7,7%202 51.38 St36.on • 1 005:f 1st ow reduction uajuste0 annual Annual Eat.coat per Total est cost Nr merow a Insert treats ant coal Savings Manhole Mean of Manacle Inserts ■CO 0 21s1 (00_tee°x[.11) 4E0 510) IOi4 x D4) ,5tH 20C ST_722 5132.355 5,30 CO 521.M.]C •!a 1st year total Total savings -7 savings over 5 years Q ICU-E14) ate+(C14K4) $111,758.40 $645,192.00 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.

According to the United States Census Bureau, the city has a total area of 11.6 km2 (4.5 mi2). 11.2 km2 (4.3 mi2) of it is land and 0.4 km2 (0.1 mi2) of it (3.13%) is water. 1.1x.- , � l' ' �_�rr Figure 2: Opa-Locka City in Florida 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. • The Biscayne aquifer under- EXPl_AN 1 JON lies pElris of our l:o'urjlies ilti Lii�t •nn no!i)tcr southeastern Florida, and consists pr�dornir•writl•y ni limestone, 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 veneer of soil, the slowly moving surface water passing over the recharge area of the aquifer is able to readily percolate downward into the aquifer. 2.5 Current Land Use pattern in the city of Opa-Locka Opa-Locka Current Land Use -ow; . 114':', n �t t V6 tv, , "Ers'. ,ii,, CnnGnl Lana V, 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.
