When The Wind Blows and Rain Pours – Don’t Be This Guy

/in , ,

Throughout the year the Lake Worth Drainage District (LWDD) is available to assist residents, board associations and property managers with understanding the operation and maintenance of the drainage system within their neighborhood and the important role they have in providing effective flood control for the community. LWDD Field Representatives are each assigned a specific area within the LWDD boundary to provide this assistance. But when the wind starts to blow and rain pours, it’s all hands-on deck! The LWDD staff’s focus switches from day-to-day tasks to storm response. During this time there is less opportunity for staff to address the public’s education or outreach needs. So don’t be this guy:

This guy mistakenly assumes it is LWDD’s role to open and close the association’s discharge control structure in response to rainfall. The operation and maintenance of the discharge control structure is a coordinated function between LWDD and the community. It is the community’s responsibility to open and close the structure in accordance with LWDD’s instructions/authorization.

This guy will call LWDD staff during the storm requesting to be included in the email distribution list. Staff will do their best to accommodate this request. However, please take time to do this before the start of storm season on June 1. Your community association may pre-designate who should be contacted for emergency alerts and instructions. This registration can be found at   www.lwdd.net/authorization-contacts.

This guy doesn’t maintain the drainage infrastructure within the community. He incorrectly assumes that LWDD staff will come out to his community and inspect and make necessary repairs throughout the year. The drainage infrastructure within the community is the sole responsibility of the association. Drainage infrastructure may include items like stormwater ponds, underground pipes, discharge control structures, swales and street drains.

This guy doesn’t keep up with vegetative removal and wonders why his neighborhood streets are flooding. Debris blocking the grate of a street drain can quickly create a localized flooding issue for a neighborhood. Unkept landscaping can topple over in high winds, damaging buildings, cars and injury to residents. Depending on where vegetation lies, blockage to drainage flow can occur. Watch this short video that demonstrates a real-life street flooding event at https://youtu.be/d5vMXatzqVc.

This guy is uninformed and doesn’t know where the key to the community’s discharge control structure is located and has never tried to open the operable mechanism. He may not have the tools needed to access the structure if located below ground. He may break the operating portion of the structure due to lack of experience. This guy will find it near impossible to resolve the issues during the weather event.

Before the wind begins to blow and rain begins to pour, visit LWDD’s Storm Response webpage at www.lwdd.net/storm-response for the information you need to keep you from becoming this guy.

Flood Protection Tips for Associations

/in , ,

The increased severity of tropical storm events and shifting rainfall patterns pose many challenges. Whenever the volume of water on land overcomes the capacity of natural and built drainage systems to carry it away, flooding can result. But steps can be taken to mitigate some of the damage caused by flooding.

The following is not an all-inclusive list but a kick start for your community to begin planning and budgeting for future mitigation projects.

  • Drainage Systems – Aging and overloaded stormwater systems can be updated to allow water to be moved, stored, and drained more efficiently.
  • Gutters – Removing leaves and other debris from clogged gutters and downspouts can prevent water from pooling around a building’s foundation. Be sure to locate the down spout in the proper direction. A down spout should never directly discharge into a canal or other water body but instead be directed to grassed or rocked areas that will allow the stormwater to slowly seep into the ground.
  • Building Exteriors – A form of “dry flood-proofing,” the application of painted coatings and sealants that you apply to your foundation, walls, windows and doorways will help prevent flood water from leaking into your structure through cracks or penetrations where utilities may come through.
  • Re-grading Property– Adjusting the slope (grade) around a building’s foundation can help stormwater flow more easily away from the building and toward drainage systems like street drains or swale areas. Re-grading may be especially effective for older communities where the grade may have settled over time or been modified by landscaping.
  • Raising Building Systems – HVAC systems and electric panels raised or relocated to above flood levels can prevent future damage to expensive systems.
  • Permeable Pavement – Permeable pavement is a type of paving material that is highly pervious and allows rainwater to pass through it, which reduces runoff. By reducing runoff, permeable pavement manages stormwater and decreases flood risk.
  • Rain Gardens -This type of green infrastructure is designed and built to mitigate stormwater flooding. A rain garden is a garden in a depressed area of a landscape that is designed to temporarily hold and soak in rainwater while providing a pleasing look to the landscape.

The Lake Worth Drainage District is committed to assisting communities within our boundary to be more informed and more resilient to potential flooding. Please visit our website for more information at www.lwdd.net.

That’s A Good Question

/in ,
  1. Where can I find information about LWDD’s early beginnings?
  2. In 2015, the LWDD celebrated its 100th anniversary with the creation of the Centennial Video Series. The series consists of 10 short videos (about 5 minutes) each covering a decade of LWDD history. You can watch the series on our website at https://www.lwdd.net/resources/videos-publications. Enjoy!
Alligator

Frisky Alligators

/in ,

The Lake Worth Drainage District (LWDD) canals and rights-of-way are abundant with wildlife even in urbanized areas. Residents may encounter various species living in and around the canal system. Most of the animals are harmless. Some can become a nuisance to residents like Muscovy ducks, raccoons and iguanas. However, some animals are dangerous and even life-threatening like alligators and some types of snakes.

The Alligator is particularly dangerous during May and June when courtship begins and continues with females laying an average of 32 to 46 eggs in late June or early July. An estimated 1.3 million alligators inhabit all 67 counties in Florida and can be found anywhere there is standing water. While alligators and people usually coexist peacefully, there have been recorded attacks and occasional fatalities. The key to staying safe is being alert to the possibility of an alligator’s presence.

Be cautious and assume that drainage canals and ponds are home to alligators. Do not swim or wade in areas where alligators are likely to inhabit, especially at dusk or night when they naturally feed. It is important to keep children away from the water’s edge and do not allow family pets to swim or explore waters if you are unsure about the wildlife inhabiting the waterbody. Feeding alligators in Florida is illegal. When people feed alligators, they lose their natural fear of people and associate humans with food.

Alligators are an important part of Florida’s ecosystem, but should always be regarded with caution. Aggressive alligators can be reported to the Florida Fish and Wildlife Commission’s Statewide Nuisance Alligator Program at https://myfwc.com/wildlifehabitats/wildlife/alligator/snap/.

Your Flood Probability

/in , ,

Within the Lake Worth Drainage District (LWDD) boundary, some homes and businesses are constructed in areas known as the 1 in 100-year flood plain but have experienced multiple floods in the same year. The assumption that if their area has experienced a 1 in 100-year flood, then for the next 99 years they do not have to worry about flooding is not correct. While it is unlikely that two large storms will happen in close succession, history has demonstrated that it is possible.

Confused by the term 1 in 100-year flood, people begin to wonder what their flood risk really is. The definition of a 1 in 100-year flood is a flood that has a 1% chance of occurring in any given year. Understanding your flood risk can be a complex process, but the hydrologists at the U.S. Geological Survey (USGS) are striving to communicate risk more effectively, in part by transitioning away from the term 1 in 100-year flood and instead referencing multiple year flooding probabilities. For example, the flooding risk of a home in the 1 in 100-year floodplain can be more easily understood as a home with a 26% chance it will flood over the course of a 30-year mortgage. Providing a clearer understanding of the probability of flood risk allows for better protection of people and buildings.

The USGS has published a flyer discussing in detail the probability of flood risk. You can download a copy at https://pubs.usgs.gov/gip/106/pdf/100-year-flood-handout-042610.pdf
