Section 8 Estimate ofProbable Capital Improvement Costs The Estimate of Probable Capital Improvement Plan Costs is provided in Exhibit 12 Design costs associated with the improvements herein before described have been estimated based on the best available information.

Last, a reasonable project contingency estimate has been included utilizing rounding factors. Please note that the costs are preliminary in nature and subject to change based on final engineering, permitting, and changes in construction cost due to market fluctuation. Section 9 Conclusions and Summary Opinion The Capital Improvement Plan as described are necessary for the functional development of the property within the District as required by the applicable local governmental agencies. The planning and design of the infrastructure will be in accordance with current governmental regulatory requirements. The public infrastructure as described in this Report will serve its intended function provided the construction is in substantial compliance with the future design and permits which will be required by the District. In addition to the annual non-ad valorem assessments to be levied and collected to pay debt service on the proposed bonds, the District will levy and collect an annual "Operating and Maintenance" assessment to be determined, assessed and levied by the District's Board of Supervisors upon the assessable real property within the District, for the purpose of defraying the cost and expenses of maintaining District-owned improvements. The construction costs for the District's Capital Improvement Plan in this report arc based on the concept plans for the District as currently proposed. In our professional opinion, and to the best of our knowledge ,.:\2015\15-114khov my.ticdune,\pm\cdd\20n0427 edd engineers report.docx Page 10of12 Windward Community Development District Engineer's Report for Capital Improvements and belief, the costs provided herein for the District are reasonable to complete the construction of the infrastructure improvements described herein. All of the proposed infrastructure Capital Improvement Plan costs are public improvements or community facilities as set forth in sections 190.012(1) and (2) of the Florida Statutes. The summary of probable infrastructure construction costs is only an 0p1Illon and not a guaranteed maximum price. Historical costs, actual bids and information from other professionals or contractors have been used in the preparation of this report. Contractors who have contributed in providing the cost data included in this report are reputable entities with experience in Central Florida. It is therefore our opinion that the construction of the proposed District Capital Improvement Plan can he completed at the costs as stated. The labor market, future costs of equipment and materials, increased regulatory actions and requirements, and the actual construction process are all beyond our control. Due to this inherent opportunity for fluctuation in cost, the total final cost may be more or less than this opinion. As District Engineer: Poulos & Bennett, LLC David M.
