SUMMARY ANALYSIS
A “special district” is a unit of local government created for a particular purpose, with jurisdiction to operate
within a limited geographic boundary. Special districts are created by general law, special act, local ordinance,
or rule of the Governor and Cabinet. A special district has only those powers expressly provided by, or
reasonably implied from, the authority provided in the district’s charter.
Mosquito control districts (MCDs) are created to protect health and safety, improve quality of life, promote
economic development, and allow for the enjoyment of natural attractions of the state by reducing the number
of insects that transmit disease within their boundaries. An MCD may contain part or all of a county or
municipality. As of February 1, 2024, there were 18 mosquito control districts: 15 independent districts and
three dependent districts.
The Collier Mosquito Control District (CMCD) is an independent MCD in Collier County created in 1950. The
charter of the district was re-codified in 2001. The CMCD originally served an area of six square miles, but has
been subsequently expanded to cover an area of 401 square miles.
The bill revises the boundaries of CMCD to include approximately 329 square miles in northern and eastern
Collier County, including the area contained in the Ave Maria Stewardship Community District that is currently
served by CMCD through an interlocal agreement. The boundary expansion of the CMCD was approved by
the Collier County Board of County Commissioners, as required by statute, and by the electors of the area
annexed into the district.
The Economic Impact Statement (EIS) projects a net decline in CMCD revenues by approximately $86,710
and $64,485 in the first and second fiscal year, respectively, as services currently paid for via an interlocal
agreement will instead be paid for by ad valorem taxation. The EIS also projects cost increases of
approximately $983,774 and $920,569 for the first and second fiscal year, respectively, associated with
acquiring additional equipment and hiring staff to service areas that are not currently serviced by the CMCD.

I. SUBSTANTIVE ANALYSIS
A. EFFECT OF PROPOSED CHANGES:
Present Situation
Special Districts
A “special district” is a unit of local government created for a particular purpose, with jurisdiction to
operate within a limited geographic boundary.1 Special districts are created by general law, special act,
local ordinance, or rule of the Governor and Cabinet.2 A special district has only those powers
expressly provided by, or reasonably implied from, the authority provided in the district’s charter.
Special districts provide specific municipal services in addition to, or in place of, those provided by a
municipality or county.3 Special districts are funded through the imposition of ad valorem taxes, fees, or
charges on the users of those services as authorized by law. 4
Special districts may be classified as dependent or independent based on their relationship with local
general-purpose governments. A special district is classified as “dependent” if the governing body of a
single county or municipality:
 Serves as governing body of the district;
 Appoints the governing body of the district;
 May remove members of the district’s governing body at-will during their unexpired terms; or
 Approves or can veto the budget of the district.5
A district is classified as “independent” if it does not meet any of the above criteria or is located in more
than one county, unless the district lies entirely within the boundaries of a single municipality.6
Special districts do not possess “home rule” powers and may impose only those taxes, ass essments, or
fees authorized by special or general law. The special act creating an independent special district may
provide for funding from a variety of sources while prohibiting others. For example, ad valorem tax
authority is not mandatory for a special district.7
Mosquito Control Districts
Mosquito control districts (MCDs) are created to protect health and safety, improve quality of life,
promote economic development, and allow for the enjoyment of natural attractions of the state by
reducing the number of insects that transmit disease within their boundaries. 8 An MCD may contain
part or all of a county or municipality.9 As of February 1, 2024, there were 18 mosquito control districts:
15 independent districts and three dependent districts. 10

DATE: 2/7/2024
The creation of new MCDs has been prohibited since July 1, 1980. 11 In counties without a district, the
board of county commissioners may exercise the rights, powers, and duties authorized by statute for an
MCD or may direct the county health department to do so. 12 For MCDs formed prior to July 1, 1980, the
district board of commissioners may request the board of county commissioners for the county in which
the district lies to approve a change in the boundaries of the district. 13
General law authorizes MCDs to levy an ad valorem tax of up to 10 mills on real and personal property
within the district.14 If an area is added to a district’s boundaries, an ad valorem tax may only be levied
in the added area if approved by a referendum in the area added to the district. 15
Collier Mosquito Control District
The Collier Mosquito Control District (CMCD) is an independent MCD in Collier County created in
1950.16 The charter of the district was re-codified in 2001.17 The CMCD originally served an area of six
square miles, but has been subsequently expanded to cover an area of 401 square miles. 18 The district
is governed by five-member board elected to serve 4-year terms.19 During the 2022-23 Fiscal Year
(FY), the CMCD was primarily funded by an ad valorem tax of 0.1609 mills. 20
Effect of Proposed Change
The bill revises the boundaries of the CMCD to include approximately 329 square miles in northern and
eastern Collier County, including the area contained in the Ave Maria Stewardship Community District
that is currently served by the CMCD through an interlocal agreement. The boundary expansion of the
CMCD was approved by the Collier County Board of County Commissioners, 21 as required by statute,
and by the electors of the area to be annexed into the district. 22
The Economic Impact Statement (EIS) projects a net decline in CMCD revenues by approximately
$86,710 and $64,485 in the first and second FY, respectively, as services currently paid for via an
interlocal agreement will instead be paid for by ad valorem taxation. The EIS also projects cost
increases of approximately $983,774 and $920,569 for the first and second FY, respectively,
associated with acquiring additional equipment and hiring staff to service areas that are not currently
serviced by the CMCD.
B. SECTION DIRECTORY:

Section 2: Provides the boundary expansion was approved by a majority of qualified electors
residing in the areas to be added in a referendum held August 23, 2022.
