Prevent Flooding – Adopt A Storm Drain

Everyone knows that trash is not good for our waterways, but many people unwittingly contribute to water pollution because they do not understand that “natural” trash like leaves, grass clippings and pet waste can become pollutants when they enter the water. Additionally, storm drains are part of the local flood control system helping to move storm water away from homes and businesses. They act as a conduit discharging storm water into local stormwater ponds and drainage canals.

When organic debris like leaves and grass wash down a storm drain, they decompose and release nutrients like phosphorous and nitrogen. These nutrients are food for algae and other aquatic plants. Additionally, people can add to the nutrient load by applying fertilizers which can wash down storm drains after a rain.

Debris blocking storm drains can be a local flooding hazard. Even an average afternoon rainstorm can cause local street flooding if the water has nowhere to go. Just a small number of organic debris and trash on top of a drain grate can reduce drainage capacity. By keeping the storm drain clear of debris, it can function as designed allowing storm water to flow away from your home and discharge into flood control canals.

Some helpful tools for cleaning a storm drain include: a broom, a rake, a trash grabber, gloves, an orange cone and/or safety vest, a shovel or dustpan and a pail or yard waste bag. Never remove the grate or otherwise attempt to clean inside the catch basin. Clean only the surface of the storm drain grate and the area around it. If the drain seems to be plugged or have any problems, contact your community board/property manager or local municipality to address the issue.

Adopting a storm drain only takes a small amount of your time. Let friends and neighbors know about your commitment and invite them to adopt a storm drain too. When we all sweep up, rake up and pick up, we protect our properties and waterways.

The Chance Your Home May Flood

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’s 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, many 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, a home in the 1 in 100-year flood plain, may be better 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 decisions to be made to better protect 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

LWDD – Post-Storm Clean-up

Following a severe storm event, the Lake Worth Drainage District (LWDD) conducts immediate post-storm assessments, inspecting water control structures, canal channels and the canal rights-of-way for vegetative and other debris with the potential to negatively impact drainage.

The public can assist by reporting storm damage via our Citizen’s Reporting System located on our website at https://lwddnet.wpengine.com/storm-response.  The user will be asked a few questions and a map will be provided to help identify the location of the incident in real-time. These public reports as well as LWDD staff assessments are reviewed and prioritized for vegetation removal. Priority is based on the following criteria:

  • High Priority – vegetation is in the water and threatening drainage
  • Medium Priority – vegetation is blocking the right-of-way and encumbering access or vegetation is significantly leaning over the waterway and could be a potential future threat to drainage
  • Low Priority – vegetation located on the LWDD right-of-way that may partially reduce access

Depending on the severity of the storm damage it may take several weeks before crews can address low priority incidents. Private property owners that wish to trim vegetation that has fallen or is leaning on their property from the LWDD right-of-way may do so at their discretion and expense. If access to the LWDD right-of-way is necessary to trim or remove vegetation, the property owner should receive prior approval from the LWDD for temporary access.

Any material from trimming or tree removal by the property owner must be properly disposed of by the resident or if applicable the contractor performing the work. Keep in mind that it is unlawful to place any debris in the canal or on the right-of-way in anticipation that LWDD will remove the material. Unlawful dumping will be reported to the authorities.

If fallen debris has damaged personal property, the individual property owner should contact their insurance company to submit a claim. The LWDD will not directly reimburse property owners for damage caused by acts of mother nature.

After a major storm event, debris clean-up is paramount to getting back to normal and the LWDD is committed to quick removal of hazardous flood prone debris for the safety of our residents.

Storm Readiness Includes Landscaping

Many residents work hard creating beautiful yards but living in Florida means we live with hurricanes. There is no way to completely protect your landscape from the effects of a severe storm, but there are some things you can do to minimize potential damage.

When a storm is approaching take time to mow your yard. This may seem unimportant at the time, but it will make debris clean-up easier, and you have one less thing to think about post-storm. Also, once the rain starts it may be days or even weeks before you can safely operate a lawn mower through the soggy soil and grass.

Do not prune trees and leave debris on site if a storm is imminent. It is better to take a chance and leave the tree intact if you cannot get the debris off site before the storm. Remove coconuts from coconut palm trees and harvest fruits from other trees that are mature enough to be picked. These items can become dangerous projectiles during high winds. If you have waited until the last minute, store debris in your garage or another safe place away from the wind.

Support small trees and tall plants with sturdy stakes driven at least 8-inches into the ground. You can also lay arches and trellises on the ground and anchor them with a rope. Masses of heavy vines growing on fences can pull fencing over in high winds. If the vines are extensive you may want to trim or remove them altogether.

In addition to wind damage, you may be faced with flooded areas of your yard for several days or weeks. Flooded conditions can seriously impact water-intolerant plants leading to fruit drop, wilting and root rot. Saturated soil coupled with high winds lead to uprooted trees, especially trees with shallow root systems. Do not add to the flooding. Turn your sprinkler system off. This includes irrigation systems with a rain shut-off device. You can reset your system to automatic when the soil dries out.

Clear house gutters of debris to ensure water from heavy rains has free flow. Make sure gutters are firmly attached and directing water away from the home. If there are no gutters and the water pours off the roof in a concentrated area, consider placing pavers or rocks in the runoff area to reduce soil erosion.  Residents adjacent to a drainage canal should also be sure that gutters are directing water away from canals to avoid washouts and bank failure.

Before the storm arrives, check surrounding areas to ensure there are no blockages that may prevent drainage. Clear debris from areas where water will flow toward, like storm drains and swale areas. After the storm, check these areas again for possible blockages.

Making landscaping a part of your hurricane readiness plan is a great way to help protect your property and landscaping investment.
