to be constructed with this project for an estimated cost of $570,000.00.(Rounded) This brings the total estimated project costs to $1,950,000.00.(Rounded) As with all such projects, the ultimate cost will be regulated by the degree of competition at the bidding of the project. Of the 723 lots and non -platted parcels, there are approximately 392 existing homes and 331 vacant lots. The attached letter from Michael J. Galanis, Environmental Health Director (Exhibit 10), lists the Dixie Heights / Dixie Gardens Developments as the next priority for making County Drinking water available based on the existing density, the poor groundwater quality, and the close proximity of wells and septic tanks. Ninety-six and one half percent (96.5%) of the properties are "undersized" according to Indian River County's Comprehensive Plan and the County Public Health Unit, Division of Environmental Health, which require that lots utilizing well and septic systems be a minimum of one-half acre. If served by a public water system, the lot may be reduced to one-quarter acre in size. Lots not meeting these minimum standards are called "undersized lots."(Exhibit 11) Typical lots sized in the proposed project are 50 x 100 feet or 5,000 square feet (0.11 acre). Staff is proposing modified assessments for several non -platted residential home sites, which appear unlikely for division or further development. (Exhibits 6 & 7). The 1508 rule has been applied to "equalize" the assessment, for these larger single family homesites. Indian River County's Comprehensive Plan states, "The County's water system shall be expanded to supply the potable water needs of the eastern half of the County during the period 1986-2005."(Exhibit 11) The attached map displays the area to benefit from the assessment project.
