The plant will be initially designed and constructed to accommodate those property owners who are interested in participating in the development of the wastewater system. It is necessary that all interested parties respond as soon as possible by completing the enclosed Letter of Intent form. The current wastewater impact fee is $1,250.00 per ERU. An important factor to be considered is if you commit now, the cost per unit will be frozen and this fee may be assessed over a long period of time. If you decide to commit at a later date, the cost per unit may be at a higher rate and paid in one lump sum. To accurately calculate the volume of wastewater service needed in equivalent residential units (ERU), residential properties will use the number of units per acre allowed based upon the zoning of the property. To calculate commercial equivalent residential units the following formula is used: Square Footage of Property x .40 x .10 divided by 250 = Equivalent Residential Units To be eligible to participate in this program, complete the enclosed form and attach a copy of the property deed or legal description and the property parcel number. Your immediate response will ensure your required capacity in the wastewater plant. Please address all mail to: Indian River County Utilities 1840 25th Street Vero Beach, FL 32960 If you have any questions, please do not hesitate to call Ron Brooks at 567-8000, extension 461. DISTRICT NUMBER LETTER OF INTENT NAME OF PRINCIPAL PROPERTY OWNER: ADDRESS OF PRINCIPAL PROPERTY OWNER: TELEPHONE NUMBER OF PRINCIPAL PROPERTY OWNER: PARCEL NUMBER OR LEGAL DESCRIPTION OF PROPERTY: I (WE) WILL COMMIT TO NUMBER OF ERUS SIGNATURE DATE June 25, 1986 Dear Sebastian Property Owner: Indian River County is about to implement a long-awaited wastewater disposal facility for the North County business district along the U.S. 1 corridor. A feasibility study for the system has been funded by a number of property owners in Roseland and Sebastian who have already committed themselves to hook up to the system as soon as it is available. This facility is necessary if we wish to attract further commercial development in the Sebastian business district. Additional commitments are required if the system is to be extended the length of the Sebastian City limits. The requirement is for 700 more Equivalent Residential Units (ERUs). The enclosed form describes how to determine the ERUs for your property. The environmental benefit of this project is obvious and so is the inevitable increase in property values that will follow. (here is also a considerable cost benefit to you for voluntarily reserving your connection now rather than later - or at a time when you may be required to do so for health reasons: Your commitment now will entitle you to a guaranteed hook-up cost of $1,250 per ERU. This fee may be amortized, at your option, over a ten to twenty year period. If you delay, later hook-up fees may be assessed at higher rates and full up -front cash payment will be required at the time of application. We need your prompt commitment so that this essential project may proceed. Please send your reply on the enclosed form to: Jeffrey Barton, Assistant Utilities Director Indian River County P.O. Box 1750 Vero Beach, Florida, 32961 Thank you.

The original Work Authorization called for a study and report to Sewer the Roseland area of Indian River County and portions of the City of Sebastian.In reuponae to that Work Authorization, our office prepared, completed and submitted the "Roseland Area Sewer Feasibility Study and Report," dated May, 1986, to Indian River County. The Report was accepted by Indian River County and subsequently the study area to be sewered was substantially expanded to the south. The County requested our office to revise and amend the original "Roseland Area Sewer Feasibility Study and Report" to include the newly expanded study area. Our office made a comparison of the new study area with the original Roseland Area and concluded that the revisions and amendments could not be properly addressed by simply revising the "Roseland Area Sewer Feasibility Study and Report." Therefore, the "Roseland Area Sewer Feasibility Study and Report" will remain in tact and we have prepared this new report entitled "North County Subregional Sewer Feasibility Study and Report," dated September, 1986. Much -1- of the contents of the "Roseland Study and Report" will be used in this report. The "North County Subregional Sewer Feasibility Study and Report" will cover a contiguous study Alrea generally bordered by the Sebastian River to the north, the FEC Railroad to the west, and the Pelican Pointe and Village of Lake Dolores development projects to the south. The report contains Exhibits which show Phase I service area limits; conceptual arterial "core" sewer system layout; and the location of parcel numbers interested in connecting to sanitary sewers. The report also contains general background information regarding the County's ongoing water and sewer programs; the need for and objectives of providing public sewer in the North County Subregional Area; a general description of the proposed arterial "core" public sewer System; a construction cost estimate and recommendations. General Background The Indian River County Commissioners, through its Utility Department, are moving forward with a progressive and well planned program of providing water and sanitary sewer facilities to the populated areas of Indian River County. About a year ago, a major water project was completed -2- involving the extension of 20" and 16" water lines from thevicinityof Oslo Road and 27th Avenue, generally west along Oslo Road and north along Kings Highway to Route 60, then west along Route 60 to its intersection with Intersate Route 95. The water project also involved the construction of a 750,000 gallon elevated water tank at the intersection of Kings Highway and Route 60. This major water project establishes the core of a water supply system for the Route 60 corridor of Indian River County, which is experiencing rapid growth. Subsequently, a major sewer project was constructed along the Route 60 corridor to furnish sewer service to this growth area. The sanitary sewer construction has been completed and primarily consists of an arterial or "core" system of pumping stations and force mains into which developers and existing development can connect. The sewer project also includes construction of a new 1.0 MGD wastewater treatment plant and effluent disposal facilities. These two major water and sewer projects are relevant to this study and report because they demonstrate that Indian River County has a proven track record of constructing Projects in a timely and cost. -effective manner. The same Proven procedures used to construct the Route 60 projects are Proposed for constructing the North County Subregional Sewer Project. -3- With regard to project financing, the Route 60 water and sewer projects were financed largely as the result of a financing partnership effort between Indian River County and Private project developers who needed water and sewer facilities to make their projects viable. This arrangement has resulted in benefits to both Indian River County and the private developers. The County benefits by having the arterial water and sewer systems constructed at no additional cost to the exiating customers of the utility systems, and the private developer benefits by having public water and sewer systems available for his project's use. The same partnership arrangement, with respect to financing between Indian River County and potential public sewer users in the North County Subregional area of Indian River County, is being proposed for this sewer project. As a matter of fact,' the funding for both this and the previous "Roseland" sewer feasibility study and report has been generated through the use of a voluntary contribution of $25.00 per Equivalent Residential Unit (ERU) received by the County from many Property owners interested in north County sewer service. The County has stressed that connection to the proposed sewer system will be voluntary and no one will be forced to connect, unless the lack of connection will result in a health problem. 1XIC It is anticipated that Indian River County will proceed with engineering and construction of the facilities deemed feasible as a result of the findings in this study and report through the use of the financing partnership between the County and private sector so successfully utilized on the two recent Route 60 corridor water and sewer projects. Need for Public Sewers The sanitary sewage needs of the North County Subregional service area are presently being met by the use of scattered small package wastewater treatment planta and on-site septic Systems. The use of package planta and septic Systems can be cost-effective and in harmony with the environment when located in rural areas with relatively low Population densities. However, public sewers are necessry in order to provide for protection of environmentally sensitive resources and to sustain orderly growth of more populated areas. Since the early 1980s, a growing number of civic leaders have been recognizing the need to provide public sewers, particularly in specific areas of the north County and the City of Sebastian. The City of Sebastian has made repeated efforts to find ways of bringing about a City-wide public -5- sewer system without success. Since the area of need for public sewer does not respect political boundaries, it appears that the common need for public sewers is serving to form a partnership between Indian River County and the City of Sebastian. First, let's discuss the need for a public sewer system in the North County Subregional Service Area of Indian River County as it relates to environmental considerations. The present discharge, either directly or indirectly, of package treatment plant effluents and septic system effluents into the Indian River and Sebastian River must cease as soon as Possible. These two rivers are irreplaeable treasures and amenities which make this area of Florida unique. They offer scenic beauty and recreational enjoyment. The present lack of public sewers will not stop growth, but will cause continued increases in the pollution load discharged into the Sebastian and Indian Rivers. Since both of these bodies of water are slow moving and have little flushing, they are prone to rapid pollution. The continued lack of public sewers will result in the destruction by pollution of these beautiful water amenities in the near future. The construction of a public sewer system which will intercept wastewater and stop pollution of the Sebastian and Indian Rivers is needed now. A second need for public sewers is created by the planned growth for specific areas of the North County Subregional Service Area. A large portion of the land bordered by the Indian River on the east and the FEC Railroad on the west, and extending from the Sebastian River bridge south, is planned for various commercial uses. Proper and orderly commercial development and growth can only occur if the infra -structure is in place to support it. One of the main elements of this infra-atructure is the availability of a public sewer system. At present, the commercial node in Roseland at the intersection of U.S. Highway pl and Roseland Road is growing rapidly even without the presence of public sewer. There are three (3) package plants in the immediate area of that commercial node and this, in itself, is evidence of the long over -due need for a public sewer system. It should also be recognized that there are some specific commercial enterprises which cannot exist without public sewers, Such as: laundromats, car washes, large restaurants, and so forth. Therefore, public sewers are needed in order to support balanced growth. Objectives The primary objective of this Sawa r feasibility study -7- and report is to establish a conceptual arterial "core" sewer system design which is cost-effective, environmentally sound, easily expanded, and acceptable to the permitting agencies. It must be understood that the proposed sewage collection and conveyance system has been conceptually designed to strategically locate and size primary pump stations and arterial force mains to serve the study area. Many property owners have shown support for this project by contributing 825.00 per equivalent residential unit (ERU) in order to finance this and the previous "Roseland" feasibility study and report. The majority of these property owner's parcels are located within the proposed Phase I service area. A list of the parcel numbers, property owners, and the number of ERUs credited, based on the feasibility study fee paid, is included in the Appendix of this report under "Schedule 'A.' -- The location of these property parcels is shown on Exhibits #1 through #5 which are included in the Appendix of this report. Subsequent to the completion of the "Roseland Area Sewer Feasibility Study and Report," and a public hearing in Sebastian early in May concerning the report, the City of Sebastian and Indian River County waged a campaign seeking additional support for this sewer project. From May to the present time, a large number of letters stating intent to -e- connect to the proposed sewer system have been received by Indian River County. The location of these properties, and number of ERUs associated with the properties, is the primary factor which has expanded the study area to the south and located the proposed wastewater treatment plant and disposal site to the west of the Whispering Palma Mobile Home Park. Exhibits N1 through M5 included in the Appendix of ,this report show the North County Subregional Sewer Study Area for Phase I of the project, as well as the property parcel number locations. Schedule "B" in the Appendix of this report is a tabulation of parcel numbers, property owner names, total ERUs, and total ERUs included in the service area based on letters of intent received by Indian River County up to August 15, 1986. As can be seen by the Exhibits in the Appendix of thi's report, many of the parcel numbers are scattered with a good deal of area between them. This situation generally results in a very inefficient and costly sewer system design. It should be understood that the most cost-effective sewer design results from serving the maximum number of possible sewer connections with the least length of sewer -- construction. A major objective of this sewer feasibility study and report is to design a conceptual arterial sewer system which -9- will form the core of a permanent utility system as opposed to some interim system. The County wishes that any cost of capital construction will represent a true investment in its overall utility program. Therefore, the conceptual engineering design will provide a core system which can be easily expanded as demand dictates and sized for the a estimated ultimate buildout of the service area. As indicated previously in thie report, the objective of preventing environmental pollution is extremely important. There are sixteen (16) existing package wastewater treatment plants located in the study area. All of the package plants will be eliminated with the proposed project, with the exception of the River's Edge plant. These package plant locations are shown on Exhibits #1 through #5 included in the Appendix of this report, and the specifics of each plant are listed below: Capacity Name (MGDs) ERUs Humana Hospital 0.030 Roseland Plaza 0.064 120.0 Riverwalk 0.020 256.0 Shady Rest 0.025 80.0 E1 Capitan 0.060 100.0 Oyster Bay 0.015 250.0 Anchor Laundromat 0.006 60.0 Sebastian Elam. 0.010 24.0 River's Edge16.0 0.015 Aspen Whis Palms 0.040 60.0 Aspen Whis Plm Too 0.035 243.0 Breezy Village 0.015 242.0 New Horizons 0.025 241.0 Vill/Lk Dolores 0.030 100.0 648.0 -10- Pelican Pointe 0.090 320.0 River Run 0.027 136.0 *Reflections 0.070 240.0 Total 0.577 3136.0 * Has no package plant - Pumps to GDU Plant In order to protect the environment, any Bawer project should strive to eliminate as many of these sixteen (16) package treatment plants as possible. In addition,• the objective of eliminating environmental pollution would dictate that public sewer serve the areas along Riverside Avenue in order to eliminate septic sewage from ultimately discharging into the Indian River. Finally, in line with the objective that a proposed wastewater collection system be designed as inexpensively as possible with respect to its construction, the conceptual' -- design of the system will minimize crossings of the FEC Railroad and U.S. Highway #1. The conceptual engineering design will reflect an attempt to balance the minimum number of pumping stations and force mains to serve the maximum amount of service area. Study Area We have prepared five (5) - 24" x 36" sheets entitled "Exhibits" which are contained in the Appendix of this -11- report. These Exhibits use as a basis, aerial photographs taken late in 1985 at a scale of approximately 1" = 400'. All sheets can be fitted together to show the Study Area including a portion of the City of Sebastian. The Exhibits show the approximate location of each parcel number which has requested sewer service and has provided Indian River County with a letter of intent up to August 15 1986. Also shown is the location of existing package wastewater treatment plants, and the proposed conceptual wastewater collection and conveyance systems. In order to determine the possible extent of the proposed conceptual gravity collection system with reasonable accuracy, spot elevations, based on U.S.C. & G. Datum, were determined by a surveyor throughout the study area. Proposed Sewage Collection/Conveyance and Treatment Facilities The Phase I service area, along with the proposed sewage collection and conveyance facilities, are shown on the five (5) Exhibits contained in the Appendix of this report. The proposed facilities have been engineered and laid out to address the objectives and needs stated in the previous sections of this report. -12- The Phase I service area is shown on the Exhibits. The service area covers approximately 2175 acres. If the total ERUs for the package plants (less River's Edge) are added to the total ERUs in the service area shown in "Schedule 'B," the result is 4983 ERUa. Therefore, the Phase I service area contains a total of 4983 ERUs or 87% of the total ERUs which have expressed intent to connect to the proposed North County Subregional Sewer System as of August 15, 1986. The remaining 746 ERUs are not within the limits of the Phase I service area primarily due to the fact that they are not close together and/or large enough to be cost-effective to sewer at this time. As can be seen on the Exhibits, the Phase I service area is bounded on the north by the Sebastian River, on the east by the Indian River, on the west by the FEC Railroad Tracks (except for the commercial center city area of the City of Sebastian), and on the south by the southern limits of the Pelican Pointe and Village of Lake Dolores developments. For the most part, the proposed collection and conveyance system consists of strategically located proposed pumping stations and a series of force mains which vary in sire from 6" in diameter to 16" in diameter. Several small sections of proposed gravity sewer are included in order to convey sewage from the existing Humana Hospital package plant -13- to pumping station #1, to convey sewage from the Roseland Plaza package plant to pumping station #2, and to make sewer service available and convey sewage from the portion of the City of Sebastian west of the FEC tracks to pumping station #3. A discussion of the proposed project components is presented as follows: Pumping Station #1 will serve a sub -area of approximately 291 acres and be located along Roseland Road. A section of gravity sewer will extend northward from pumping station #1 to the Humana Hospital package treatment plant. The Riverwalk Shopping Center sewage will be directed to pumping station #1 and both the Humana and Riverwalk package plants would be phased out. Pumping station #1 would have a design capacity of approximately 600 gallons per minute, and discharge via a proposed 10" force main following the route as shown on the Exhibits. The 10" force main would pass by the Shady Rest package plant and the Shady Rest sewage would be pumped into the proposed 10" diameter force main thus allowing the phase out of the Shady Rest package plant. The proposed 10" force main would travel south along the west side of U.S. Highway #1, which would permit properties between U.S. Highway #1 and the FEC Railroad to abandon their septic systems by installing small grinder pumps to pump their sewage .into the proposed 10" force main, and 16" force -14- main from St. Sebastian Catholic Church south to the Whispering Palms Mobile Home Park. Pump station N2 services a sub -area of approximately 282 acres and would have a design capacity of approximately 600 gallons per minute. A section of gravity sewer would extend north along Riverside Avenue and west along Roseland Road, and provide for the connection of the Roseland Plaza sewer system and the phase out of the Roseland Plaza package plant. A 10" diameter force main would be construction south along Riverside Avenue, and sewage from E1 Capitan, Oyster Bay and the Anchor Laundromat would be pumped into the proposed lo" diameter force main thus allowing the phase out of these three package plants. Also, existing septic systems would be eliminated along Riverside Avenue by installing small grinder Pumps for discharge into the lo" force main. The 10" force main and the discharge from pumping station #3 would manifold into a 12" force main for connection to the 10" and 16" force main along the west side of U.S. Highway kl. Pumping station #3 would serve a sub -area of approximately 363 acres and have an approximate design capacity of 750 gallons per minute. A section of gravity sewer would extend westward from pumping station N3, crossing U.S. Highway N1 and the FEC Railroad tracks, andIterminating with a manhole in the general vicinity of Main Street and -15- Louisiana Avenue. It is anticipated that public and/or private development will collect and convey the sewage from the Sebastian City Hall area as well as the Sebastian Elemantary School and Orange Heights area, to the manhole provided at the intersection of Main Street and Louisiana Avenue. The sewage will then be conveyed to pumping station #3 via the gravity sewer and pumped south in the 16" diameter force main. Pumping station #4 serves a sub -area of approximately 102 acres and will have a rated capacity of approximately 220 gallons per minute. It is anticipated that public and/or private development will provide for the necessary gravity sewer extensions north and south of pumping station #4 for ultimate complete sewering of the area. Sewage from pumping station #4 will be discharged via a 6" force main west into the 16" diameter force main. The existing River Run pumping station will be retrofitted to serve a sub -area of approximately 54 acres and have a design capacity of approximately 180 gallons per minute. The River Run pumping station will discharge via a 6" diameter force main south, along the east side of U.S. Highway #1, and connect to the existing 6" toree main which serves the Reflections project and presentlycrosses U.S. Highway #1. The Reflections pumping station will serve a -16- sub -area of approximately 50 acres and be retrofitted to meet a design capacity of approximately 180 gallons per minute. The sewage from both the River Run pumping station and Reflections' pumping station will discharge into the 16" diameter force main along the west side of U.S. Highway Sl. Thus, the River Run pumping station will allow the phase out of the existing River Run package plant. The 16" force main along the west side of U.S. Highway kl will turn west along the north boundary of the Whispering Palms Mobile Home Park and permit the Whispering Palms sewage to be pumped into it, and the phase out of the Whispering Palm wastewater treatment plant. The 16" force main then crosses under the FEC Railroad and terminates at the proposed wastewater treatment plant/effluent disposal site. The Exhibits show the Pelican Pointe pumping station to be retrofitted to serve a sub -area of approximately 80 acres and have a design capacity of approximately 300 gallons per minute. This will permit the phase out of the Pelican Pointe package plant. An 8" force main from the Pelican Pointe pumping station will travel north along the east side of U.S. Highway N1 to Vickers Road and allow propert4es between U.S. Highway 01 and the Indian River to connect to it by means of their own private pumping stations. The 8" force main crosses U.S. Highway 41 and travels west along Vickers.Road -17- and allows the sewage from Whispering Palms "Too" to be pumped into it and the phase out of the Whispering Palms "Too" package plant. The 8" force main then crosses the FEC Railroad tracks where it connects to another 8" force main from the Village of Lake Dolores pumping station. The existing Village of Lake Dolores pumping station will be retrofitted to serve an area of approximately 150 acres and have a design capacity of approximately 350 gallons per minute. The existing Village of Lake Dolores package plant will be phased out and the Village of Lake Dolores pumping station will discharge via an 8" force main north along the west side of the FEC Railroad which will permit the Breezy Village sewage to be pumped into the 8" diameter force main and the phase out of the Breezy Village package plant. The 8" force main will then join with the 8" force main on Vickers Road and travel west in Vickers Road as a 12"• diameter force main turning north and into the proposed wastewater treatment plant/effluent disposal site. The -- sewage from the New Horizons Mobile Home Park will be pumped into the 12" force main and the New Horizons L ckage plant phased out. The proposed wastewater treatment plant for Phase I will have a design capacity of 1,000,000 gallons per day and be designed as a secondary treatment plant. Indian River County is presently evaluating the site as shown on the Exhibits. Appraisal reports are being prepared and an engineering study will be underway shortly to determine the effluent disposal capacity of the proposed site and the actual amount of land needed by the County to provide for the ultimate anticipated subregional capacity which may be required. For purposes of _. this study and report, we are assuming that effluent disposal will be by some means of rapid infiltration and that only --- secondary treatment will be reqired. We are, therefore, estimating that the first 1 MGD treatment plant and effluent disposal facility will require approximately 20 acres of land. However, we are anticipating the need for a total of 80 acres for the ultimate total plant capacity since this is the same area acquired by the County for the "West Subregional Plant." Cast Estimates 'B A cost estimate has been prepared for the proposed Phase I project as shown on the Exhibits and discussed in detail in this study and report. It should be understood that the cost estimate is prepared and presented for budget purposes and is subject to revision and refinement during the design stage of the project.

Based on the assumption that each one of these ERUs results in the payment of a 91,250.00 impact fee to the -20- County, the total revenues obtained for this project would be 86,228,750.00. This would result in an excess of revenues over expenses of approximately 81,063,990.00. Therefore, it appears that this project is very strong financially since there is a very comfortable margin of anticipated revenues over the total estimated project cost. a Summary and Recommendations This feasibility study and report for the North County Subregional Area of Indian River County has evaluated the possibility of constructing a public sanitary sewer system to be financed on the basis of proposed user financing and voluntary connection. Indian River County has a proven track record of constructing several recent water and sewer utility projects in this manner. eeqI The need for public sewers in the study a4d service area is stated in terms of environmental considerations and planned growth for specific areas of the North County and the City of Sebastian. Any proposed sewer system must be designed and constructed in a manner to satisfy these needs in addition to being cost-effective, environmentally sound, easily expanded and acceptable to permitting agencies. The _ proposed sewer project should also serve to eliminate all -21- possible existing package wastewater treatment plants and septic systems located within the service area. A thorough and comprehensive evaluation of the study and service area has been made using elevations obtained from field surveys for this project and recently prepared aerial photographs of the study and service area. Exhibits have been prepared and are contained in the appendix of this report which show the results of our engineering evaluation and recommended sewer facilities. The proposed Phase I service area contains approximately 2175 acres and 4983 ERUs which represent over 85% of all property owners who submitted lrttters of intent to Indian River County to connect to the proposed sewer system as of August 15, 1986. The proposed sewage collection conveyance and treatment system will generally consist of seven pumping stations, force mains sized from 6" to 16" in diameter, several short sections of gravity collection sewer, and a 1.0 MGD secondary wastewater treatment plant with effluent disposal by means of rapid infiltration. The total estimated project cost for the proposed project is $5,164,760.00 which includes 80 acres of land for the initial 1.0 MGD treatment plant and effluent disposal system and future plant expansion. The anticipated revenues from the 4983 ERUs exceed the total estimated project cost by 91,063,990.00 and it is, therefore, concluded -22- that the project is viable from a financial point of view. It is our recommendation that Indian River County and the City of Sebastian governing bodies review this "North County Subregional Sewer Feasibility Study and Report." A public meeting has been scheduled for 7:00 pm on September 25, 1986 in the City of Sebastian, in order to make the contents of this report known to the public and obtain the public's input.
