Storm Water/Lakes Management Division
Wet lands

Stormwater runoff from residential and commercial development has been demonstrated to discharge a diverse array of pollutants into the receiving waters (streams and lakes). Drainage system improvements are necessary as the City experiences growth and to correct existing deficiencies within the system.


The Stormwater Division is funded by the Stormwater Utility Fee and is responsible for the operation, maintenance and repair of the City's stormwater system. The stormwater system includes a wide variety of curb inlets, drop structures, pipes and culverts, roadside swales, ditches, natural creeks, retention ponds and lakes. This division is guided by the Stormwater and Lakes Managment Master Plan (adopted 2017). 

The City is a co-applicant with Seminole County for a federal National Pollution Discharge Elimination System (i.e. stormwater) permit. To evaluate the effectiveness of our efforts, the City established a surface water quality management plan to monitor and protect the quality and function of surface water resources. This includes local management of and involvement with the University of Florida's Lake Watch program.

Additionally, the City collects quarterly data on 12 of the City's lakes. The City actively supports the Seminole County Watershed Atlas and contributes all of our lake water quality monitoring data for inclusion in the Atlas.

Mosquito Control

The Stormwater Division also manages the City’s Mosquito Control Program.  The Stormwater managers are all licensed and have received ample training and are thus capable of successfully managing an elaborate program. 

The City’s mosquito control program larvicides all retention ponds and ditches throughout the City.  This process is performed to prohibit the growth of infant mosquitoes into flying, biting adults.  The City also sprays for mosquitoes on a complaint-basis; usually on every Thursday, beginning at dusk.  All chemicals used are guaranteed safe and harmless to adults, children, animals, and the environment.


The Mosquito Control Program is governed and inspected by the State of Florida Department of Agriculture and Consumer Services and the Public Health Pest Control Division.

The City of Casselberry is partnering with Seminole County and other surrounding cities on a unified effort to manage mosquito activity.  Please click here to request assistance.

Florida Yards and Neighborhoods Program
As part of its public education efforts for the City of Casselberry community, the Public Works Department partners with the Seminole County “Florida Yards and Neighborhoods” Program, administered through the University of Florida/IFAS. Among other activities, the City hosts resident workshops to teach the nine principles of Florida-friendly landscaping, including proper plant selection, reducing stormwater runoff, protecting waterfronts, and watering efficiently. Be sure to check the City’s calendar and look for announcements for upcoming workshops, or call the Public Works office at (407) 262-7725.

By participating in the Florida Yards and Neighborhoods Program, the City hopes to help its residents and business owners learn more about how they can help protect the City’s lakes and water quality, reduce pollution, conserve water, and save time and money.
