Introduction

July 1, 2019

The Coronado Community Development District (the “District”) was created for the purpose of financing, acquiring or constructing, maintaining and operating a portion of the infrastructure necessary for the development within the District. Coronado (the “Development”), is a residential development located entirely within the City of Doral, a municipality within Miami-Dade County, Florida. More specifically, it is located in Section 7, Township 53 South, and Range 40 East. The District is situated approximately ¾ of a mile east of State Road 821 (Homestead Extension of Florida’s Turnpike), 3 miles west of State Road 826 (Palmetto Expressway) and 3 miles north of NW 41 Street. (See Exhibit 1, Location Map). The District is bounded by NW 109 Avenue on the west, NW 90 Street on the north, NW 107 Avenue on the east and NW 88 Street on the south. (See Exhibit 2, Vicinity Map).

The public facilities infrastructure is a network of onsite and offsite roadways, stormwater drainage, water and sanitary sewer systems that gives access and service to 327 condominium dwelling units located within 12 buildings (See Exhibit 3, District Boundary). The lands within the District encompass approximately 17.40 acres which include 14.40 acres of residential tracts and a 3.00-acre lake tract.

This 2019 Public Facilities Report (the “Report”) is intended to comply with the requirements of Section 189.08, Florida Statues.

Description of Existing Public Facilities, Ownership and Operation

Roadway Improvements

The offsite roads (portions of NW 109 Avenue, NW 90 Street, NW 107 Avenue and NW 88 Street) were completed and are in good condition. The right of ways for 109 Avenue, 90 Street and 88 Street were conveyed to the City of Doral and the Right of Way for 107 Avenue was conveyed to Miami-Dade County via Plat (Miami-Dade County Official Records Book 165, Page 62). The City of Doral and Miami-Dade County own and operate the offsite roads. Construction of the onsite roads was completed. The onsite roads are owned by the Coronado at Doral Master Association. On March 25 of 2008 the District was granted an access and drainage easement to encompass the onsite roads and related drainage facilities. The easement was recorded at ORB 26299, PG 143.

Funds will be needed to replace the wearing roadway asphalt layer in about 18 years, when the asphalt has reached its estimated 30-year service life. The District Board of Supervisors may decide whether to create a sinking fund to finance the future capital expense over the next 18 years or to pay a lump sum amount at the end of the asphalt service life. The table below provides the estimated future replacement cost and the estimated annual contributions over the remaining service life to fund the expense. The calculations below assume an annual interest rate of 0.25%.

Drainage and Stormwater Management Improvements

July 1, 2019

The drainage stormwater management and drainage improvements were completed and are in good condition. The improvements consist of inlets, manholes, pipes, exfiltration trenches, lake and outfall  pipe. On March 25, 2008, the District was granted the lake tract by the Developer at no cost. The Special Warranty Deed was recorded on ORB 26299, PG 136. On April 23, 2004, Century Homebuilders, LLC granted the Developer a drainage easement for the construction of the offsite outfall (ORB 23011, PG 4319) and on March 25, 2008 the Developer assigned the offsite outfall drainage easement to the District (ORB 26299, PG 166). The District owns and operates the drainage and stormwater management system.

The following is a suggested 5-year cyclical program for servicing the inlets, manholes, pipes and French drains of the drainage system. The program consists of servicing 20% of the system every year so that at the end of the fifth year, 100% of the system will have been serviced. The table below shows the estimated amount that would need to be budgeted yearly to service the 68 drainage structures and 3,310 Linear Feet of pipes in the District.

Water and Sewer Improvements

The water and sewer infrastructure was completed and conveyed to the Miami-Dade County Water and Sewer Department (WASD) for ownership and operation, together with the appropriate easements recorded at ORB 25706, PG 2325 and ORB 26224, PG 3657 (See Exhibits 6 and 7, Water Distribution and Sanitary Sewer Systems). Concerns may be reported to WASD at either of the following numbers: 305- 274-9272 (Emergencies) or 305-665-7477 (Customer Service).
