INTRODUCTIONS A. General The Northern Palm Beach County Improvement District (District) was created by Chapter 59-994 Special Acts of Florida and operates according to certain provisions of Chapter 298, Florida Statutes and Chapter 59-994, Special Acts of Florida, as amended. The District was created to preserve and protect water resources for sanitary or agricultural purposes or when the 1111 same may be conducive to public health, convenience or welfare. The District was subsequently empowered to construct and maintain public utilities including water and sewer, drainage, i irrigation, water management, roadway or related activities including offsite improvements in Palm IIIIBeach County in an area more particularly described in the Special Act, as amended, creating the District. B. . Previous Investigations -; The land area included within this Unit has experienced significant flooding in the past. In '. 1983, the Towi\of Jupiter initiated a study to determine the cause and provide recommendations to r__f alleviate this flooding. Early findings of the study determined that the natural drainage basin which contributes to the reported flooding encompasses properties within the municipal jurisdictions of the Town of Jupiter and the Village of Tequesta. Additionally, Palm Beach County had significant involvement by virtue of roadway improvements planned for Old Dixie Highway within the Unit boundary. Cooperative efforts among these governmental entities continued for several year to j identify the extent of the drainage basin, identify improvements to provide positive drainage while meeting regulatory requirements, and to develop estimated costs to implement the program. In _` September 1991, the three governmental entities requested involvement by Northern Palm Beach 5 County Improvement District to facilitate implementation of the proposed drainage system. On September 20, 1996, the District reviewed voting results which indicated that at least 51% of the landowners approved the formation of the Unit. On October 4, 1996 and November I20, 1996, Resolutions designating and confirming, respectively, NPBCID Unit of Development No. 36 were approved. npbcun36n3601.00roo I jmkm.wp 1 1 � , • C. Authori atinn _- This Plan of Improvements is authorized by.the Board of Supervisors of the Northern Palm Beach County Improvement District at the request of more than 51% of the current Landowners. As a prerequisite to implementation of this Plan of Improvement, the Landowners are obligated to disclose the existence of this Plan of Improvements to prospective buyers, pursuant to a disclosure ti_ document to be approved by the District. D. Acknowledgements This Plan is based in part on data and exhibits provided by the Landowner's engineer, Kimley-Horn and Associates, Inc., the Engineer for the Town of Jupiter. • The District Engineer would like to acknowledge the efforts of the involved governmental entities and Kimley-Horn and Associates, Inc. in working with the District to provide information used in this Plan. • E. Purpose and Scope The purpose of this Plan of Improvement is to present the nature,:extent and cost of the proposed improvements which maybe funded by the District and maintained by either the District or another similarly empowered overnmental entity. The text of this Plan generally describes the improvements, the estimated costs associated with implementing the improvements and recommendations. This Plan is not intended to be used for exact representation or for construction purposes. Detailed construction plans and specifications will be prepared for the improvements authorized by this Plan. F. Lands in Unit No. 36 The land area within Unit No. 36 encompasses 60.58 acres more or less and is located within the corporate boundaries of the Town of Jupiter and the Village of Tequesta. Exhibit No. 1 shows the general location of Unit No. 36 in relation to the northern region of Palm Beach County. The Unit Boundary map (Exhibit 2) reflects the lands to be included in Unit 36. The Legal Description of Unit 36 is shown as Exhibit No. 3. Unit No. 36 is located south of Tequesta Drive, west of US Highway No. 1 and State Road Alternate AIA, and north of Riverside Drive. Unit 36 lands are located within Section 31,Township 40 South, Range 43 East. Excluded from the unit is the Florida East Coast Railroad right-of-way. npbcun36n360I.00roo I jmkm.wp 2 • r-_ 1— II. EXISTING CONDITIONS A. Topography , IThe land surface in Unit 36 ranges from elevation 8.5 to 20 feet NGVD (Exhibit 4). The lands within the Unit are developed with the exception of isolated lots. • _i,_ B. Climatolo' Unit 36 is located in a subtropical climate zone. Winters are generally mild to dry while summers are usually warm and rainy. The annual temperature averages approximately 75 degrees t Fahrenheit. Approximately 70 percent of the annual 60 inches of rainfall occurs between June and October. Maximum and minimum annual recorded rainfall in this area are 100 inches and 40 inches, respectively. :1, C. Soils and Vegetation V The United States Department of Agriculture Soil Conservation Service Soil Survey of iPalm Beach County, Florida, identifies the existing soils in this area as St. Lucie Sand. The area is . developed and therefore very little native vegetation exists. . D. Utilities Potable water is provided by the Village of Tequesta and sanitary wastewater service is provided by the Loxahatchee River Environmental Control District. Florida Power and Light miN Company provides electric service and Southern Bell provides telephone service. E. Land.Use and Zoning I A portion of Unit 36 is located in the Town of Jupiter, and a portion of the Unit is located in the Village of Tequesta. Zoning and land use regulations are in place and administered by the governing entity. F. Drainage . IThe existing drainage (Exhibit No. 4) is primarily via overland flow. There are existing conventional pipe and inlet drainage facilities within the basin which are shown on Exhibit No. 5. I The drainage basin has no outfall facility or capability, which results in frequent and severe flooding. 111 1 npbcun36n3601.00rooIimkm.wp 3 . 1 . ,--_____ , LI III. PLAN OF IMPROVEMENTS _ r A. Surface Water Management System, 1. Regulatory Requirements . L_, TThe proposed storm drainage collection, conveyance, and outfall facilities are designed to satisfy the water quality requirements of SFWMD. The improvements received conceptual approval, Permit No. 50-01859-5, from the South Florida Water Management District on May 11, in 1989. For water quality enhancement, "Best Management Practices" and other "state of the art" r techniques which may arise are planned for incorporation into the construction plans for the Project. • A discharge capacity of approximately 80 cfs Was arrived at through the use of flood routing calculations and is designed to prevent flood stages from reaching the lowest floor elevations within the service area under the 100-year, 3-day storm event. 2. Description of Improvements i - — Elements of the water management system for Unit 36 are shown on Exhibit 5. There are existing facilities which collect stormwater runoff. The proposed'.improvements consist of a conveyance system and an outfall system. The outfall system will`discharge into an existing manmade wetland which discharges into the Loxahatchee River. 1 I B B. Rights of Way The District will require certain rights of way and easements as necessary for the operation. and maintenance of the water management and outfall system. Included will be access to the 4 conveyance and outfall system and other areas as required. I A component of this project is the purchase of right-of-way from the FEC Railroad for Iinstallation of the conveyance/water quality components of the system. The cost of acquiring this right-of-way is included in the estimated cost of implementation. 1 C.
