Century Gardens at Tamiami CDD 2022 Report for the 2007, 2014, 2017 & 2018 Projects

Alvarez Engineers recommends considering the following suggestions for future maintenance budgets:

District Roads, 2007 Project (all roads within), 2014 and 2017 Projects (roads in the townhomes and former Tract B areas)

Funds will be needed to replace the wearing roadway asphalt layer in about 15 years for the 2007 Project and about 22 years for the 2014 and 2017 Projects, when the asphalt has reached its estimated 30-year service life. Funds will also be needed to update signs and markings on the roadways in about 5 years for the 2007 Project and about 10 years for the 2014 and 2017 Projects, and subsequently restored approximately every 10 years. The District Board of Supervisors may decide whether to create a sinking fund to finance the future capital expense yearly, or to pay a lump sum amount at the end of the asphalt service life. The tables below provide the estimated future replacement costs and the estimated annual contributions over the remaining service life to fund the expenses. The calculations below assume an annual interest rate of 0.25%. The program may be financed yearly or in one lump sum when needed, at the discretion of the Board of Supervisors.

Stormwater Drainage, 2007 Project (all roads within), 2014 and 2017 Projects (roads in the townhomes and former Tract B areas)

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 all the drainage structures and pipes in the District less the ones in the Single-Family Homes area and 151 Ct, for which the County is responsible. The program may be financed yearly or in one lump sum when needed, at the discretion of the Board of Supervisors.
