3 4/17/2017 Alvarez Engineers, Inc. I. Introduction. Enclave at Black Point Marina Community Development District (the District or CDD ) was established by the adoption and enactment of Miami-Dade County Ordinance No on September 26, Such Ordinance became effective on October 6, In February of 2007 the CDD issued $3,380,000 in Special Assessment Bonds, Series 2007A and $7,790,000 in Series 2007B to partially finance the public infrastructure that supports the development within the boundaries of the District (the Original Public Improvements ). The Original Public Improvements, which are described in the Engineering Report prepared by Ford Engineers, Inc. dated October 17, 2006 (the Original Report ), consist of onsite roadway improvements, onsite stormwater management system, and water and sanitary sewer improvements. On February 5, 2014, Alvarez Engineers, Inc., the current District Engineer, certified the completion of the Original Public Improvements. As each of the components of the Original Public Improvements was completed, the CDD either conveyed the completed facilities to the County, or retained them for ownership and maintenance. As a result, the County now owns the onsite road right of ways, together with the roadway improvements, drainage, water and sewer facilities within. The District retained ownership of the two stormwater management lakes, a park and a landscaping tract. The County and the District-owned facilities are shown in Exhibits 1 and 2, respectively. The District is currently proposing to refund the outstanding Series 2007A Bonds through the issuance of its Special Assessment Refunding and Improvement Bonds, Series The District intends to use a portion of the debt service savings and proceeds from the bond refinancing to construct additional public infrastructure that will benefit the property within the District (the Supplemental Public Improvements ). The estimated construction costs of the Supplemental Public Improvements presented in this 1 st Supplemental Engineer s Report (the Report ) will be allocated to each of the residential units within the District in accordance with the proportional benefit received by each unit. This Report supplements the Original Report. Refer to the Second Supplemental Assessment Methodology Report prepared by Governmental Management Services-South Florida, LLC ( GMS ) for a description of the allocated benefits. II. Purpose of this 1 st Supplemental Engineer s Report.
