Re:	Century Gardens at Tamiami Community Development District.
Yearly District Engineer’s Report for Fiscal Year 2025-2026
Pursuant to Section 9.21(b) of the Master Trust Indenture as it relates to Special Assessment Bonds, Series 2007, 2014, 2017, and 2018.

Dear District Manager,

This statement is being made pursuant to Section 9.21(b) of the Master Trust Indenture between Century Gardens at Tamiami Community Development District (the “District” or “CDD”) and Region’s Bank as trustee dated May 1st, 2007, as it relates to the Special Assessment Bonds, Series 2007A & 2007B, (the “Original Project”). This statement is also being made pursuant to Section 9.21(b) of the Master Trust Indenture between the District and Wells Fargo, National Association as trustee dated November 1st, 2014, as it relates to the Special Assessment Bonds, Series 2014, Series 2017, and Series 2018 together, the 2014 Project (the “Expansion Area Project”), the 2017 Project (the “Tract B Assessment Area Project”), and the 2018 Project (the “Clubhouse Acquisition Project”). With this statement we are setting forth (i) our findings as to whether such portions of the CDD Project still owned by the District have been maintained in good repair, working order and condition, and (ii) our recommendations as to the proper maintenance, repair, and operation of such portions of the CDD Project during the ensuing Fiscal Year 2025-2026, and an estimate of the amount of money necessary for such purpose.

District Property and Condition. As of the date of this statement, the land tracts shown in Exhibits 3 and 4 attached to this statement, together with the completed public infrastructure within the tracts, including entrance features, roadways, and stormwater drainage, have been completed and conveyed to the District for ownership and maintenance. Such land tracts and infrastructure are in good repair, working order and condition.

Operations and Maintenance of District Property. We think that for Fiscal Year 2025- 2026, the District proposed amounts for field operations are adequate to properly maintain, repair and operate most of the public infrastructure for which the District is currently responsible. (Refer to Financials – Century Gardens Tamiami Community Development District for the FY 2025-2026 Proposed Budget).

We recommend that the District create a sinking fund to finance the future capital expense at the end of the service life of the pavements within the District roadways. The table below provides an estimate of the replacement costs at the end of the pavement service life and the estimated annual contributions over the remaining service life to fund the future expense.

We recommend that the District consider creating a 5-year cyclical program for servicing the inlets, manholes, pipes French drains and endwalls of the stormwater 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 be serviced. The tables below show the estimated amount that would need to be budgeted yearly to service the approximately 254 drainage structures and 13,712 Linear Feet of pipes in the District. It is also estimated that 10-11 baffles will need to be replaced yearly. The program may be financed yearly or in one lump sum when needed, or at any other period combination, at the discretion of the Board of Supervisors.
