Municipal Service Benefit Unit (msbu) Program





Creating a MSBU for receiving and funding lake management services, such as lake restoration and aquatic vegetation management is an option available to the owners of waterfront property located in unincorporated Seminole County. Such activities serve a public purpose by protecting or enhancing the environmental qualities, utility, and/or stormwater management aspects of a waterbody. The creation of a lake management MSBU, as well as the on-going efforts to provide improvements requires community involvement and support.


A lake management MSBU may be established to accommodate a one-time restoration project or to address ongoing management of a waterbody with aquatic vegetation management as a primary objective. Restoration projects will utilized the capital improvement MSBU format with a one-time assessment levy along with repayment by annual installments. Ongoing services utilize a variable rate MSBU format with an annual assessment. All properties that have special benefit as a result of the lake management services will be required to share in the service cost as all such properties will be assigned an equitable assessment.


The basic criteria for qualifying for these types of projects for MSBU funding are as follows:

  • The properties to receive special benefit from the services must be within the jurisdictional boundaries of unincorporated Seminole County. [Boundaries may be extended to other governmental jurisdictions if special agreements are established with other local government entities.]
  • The assessment boundary of the MSBU must include at least two assessed parcels.
  • Project must be supported by majority [65%] of the owners of specially benefited property.
  • Aquatic Vegetation Management and/or Restoration services are offered for a natural waterbody classified as a lake, pond, or waterway. [Constructed stormwater control features such as retention or retaining ponds are eligible for functional renovation services, but are ineligible for ongoing maintenance services. If the waterbody requiring renovation is classified as a retention pond (stormwater management) lake, rather than a retention pond, please obtain an MSBU application packet for Construction: Retention Pond Renovation.]


When property owners are interested in establishing an MSBU for lake management services, Seminole County’s MSBU Program and Lake Management Program partner together to coordinate a lake management plan for the waterbody. The lake management plan takes into consideration the needs of the waterbody, best lake management practices, outcome desired by the community, and budgetary constraints. The management plan, and subsequently the scope of services may contain several features:

  1. Chemical control of noxious/invasive aquatic plant species through herbicide treatments
  2. Biological control involves stocking with triploid grass carp fish (when hydrilla management is targeted in the service scope), and/or shoreline replanting with native plants. Note: Shoreline replanting is conducted independent of MSBU funding and is deemed a property owner activity (unless otherwise scheduled as a participatory planting event with other residents and volunteers).
  3. Mechanical removal of noxious aquatic vegetation. Disposal alternatives will be evaluated based on site location, nature and volume of vegetation to be removed.
  4. Excavating to remove accumulated sediment. Disposal alternatives will be evaluated based on site location, nature and volume of sediment to be removed.

Lake restoration plans may include all features listed, while aquatic vegetation management plans are typically limited to features 1, 2 and 3.

The lake management services offered through the Seminole County MSBU Program are restricted to the activities deemed critical to restoring, developing and/or maintaining conditions that enhance the water quality and over-all health and utility of the respective waterbody; with aquatic vegetation management being limited to the water and the shoreline when/where noxious, invasive, and/or exotic vegetation could/would threaten or impede the waterbody. Native vegetation and/or vegetation that do not present a detriment to the waterbody as determined by the Seminole County Lake Management Program are not targeted as a priority within the scope of aquatic vegetation management services.

Detailed information and application is available in the Lake Management MSBU Application Packet. Additional information about lake management and riparian stewardship are also available from the Lake Management Program.
