Hurricane Season And Flood Control 
Be ready for severe weather and localized flooding
The Atlantic Hurricane Season begins June 1 and runs through November 30, bringing with it the potential for severe weather and localized flooding. In South Florida, flood control is a shared responsibility and is achieved through an interconnected, three-tiered drainage system. This three-tiered system is made up of tertiary or n eighborhood drainage systems operated by property owners or residential associations, secondary drainage systems operated by local drainage districts, county or municipalities, and the primary system operated by the South Florida Water Management District (SFWMD). These three systems work together to provide effective flood control.

Water managers in charge of primary and secondary systems are continually monitoring the weather and canal levels in order to proactively respond to changes in canal elevations. In anticipation of a storm or heavy rainfall event, water managers  will make operational adjustments to maintain appropriate water elevations for flood control. Additionally throughout the year, routine canal maintenance is conducted to provide unobstructed flow of water and clear access to canal rights-of- way.
 
Local communities and neighborhoods have a similar role. They must maintain the community's drainage infrastructure to ensure that inlets, pipes and control structures are free of potential blockages thus maintaining the flow of stormwater within their community. Inspection of drainage infrastructure and repairs should be completed before the start of storm season. More information on the three-tiered system can be found at www.lwdd.net.
Design of the Neighborhood Control Structure
Two types of neighborhood structures: fixed and operable
Wooden Board Riser
Most modern day communities utilize a control structure to regulate their rate of stormwater discharge. Excess stormwater from neighborhood drainage systems will continually discharge into secondary drainage canals until the designed and permitted water elevation is achieved in community lakes and ponds.  

There are two types of control structures; fixed and operable. A fixed structure does not have a mechanism to make manual adjustments to the discharge of stormwater. An operable structure has a plate, wooden board or weir that can be opened or closed manually to release additional, excess stormwater.
 
Operable Weir Plate
Neighborhood control structures should not be opened during storm events. This is to prevent canal water from back-flowing into  community lakes. The District may provide authorization to open neighborhood control structures, but only before or after a severe rainfall event, and only when the canal system is able to accept the increased volume of stormwater. Individuals who are responsible for the operation of control structures should register with the District at www.lwdd.net/2296-2.
Coordination is Key to Effective Flood Control
Requesting to open a control structure
Individuals responsible for monitoring and operating a community's drainage system may request authorization to open a control structure to increase stormwater discharge by calling the District office, Monday through Friday from 8am-5pm at 561-498-5363. Also, the District provides updated instructions on the operation of control structures before, during and after a storm event through email notifications or recorded messages on the District's Storm Line at 561-495-4054. Sign up to receive email notifications at www.lwdd.net/enotifications.

District staff are available to assist property owners and community leaders in understanding how their drainage system works and the role they play in providing flood control. Speakers on various water management topics are also available. Send your questions or speaker request to info@lwdd.net.
Get to Know the Board of Supervisors
An introduction to Supervisor Harry Raucher
Harry Raucher
Harry Raucher was elected to the Board of Supervisors in May 2011. He represents Sub-District 4, which is generally located south of the District's L-28 Canal and north of the Hillsboro Canal, between the Florida Turnpike and State Road 7.

Raucher is a graduate of the University of Connecticut, and currently resides in the Valencia Falls community in Delray Beach. He served as President of the Eastern Connecticut Chamber of Commerce in Norwich, Connecticut for ten years, and is currently a board member of the Democratic Club of Greater Boynton.

Raucher places great importance on public outreach and local government participation. In his role as Supervisor, he attends many community and water management advisory board meetings to keep abreast of the needs of the community and regulatory requirements. Visit the District's website at  www.lwdd.net, to learn more about the members of the Board of Supervisors.
