THE ELEPHANT IN THE ROOM-AGING INFRASTRUCTURE
Flood control happens in unison. There is a three-tier system that plays a significant role in protecting our residents. Neighborhood drainage systems, or tertiary systems, are operated by property owners or residential associations. Secondary flood control canals are operated by the Lake Worth Drainage District, and primary flood control is provided by the South Florida Water Management District.
Most culverts, or water pipes that go under the surface, in the U.S. were originally estimated to last between 40 and 50 years before needing replacement due to wear and tear. However, many are now approaching the end of their lifespan, creating significant challenges exacerbated by factors such as population growth and poor planning.
When these culverts begin to reach their lifespan, they can create serious issues for the system. A neighborhood’s excess water drains into community ponds through street and yard drains. A collapsed culvert under a roadway could bring down the road and disrupt a neighborhood. The cost associated with this can range anywhere from $40,000 to north of $1 million depending on what the actual issue is. This is a massive cost to spring onto homeowners.
It is crucial to ensure that both plans and funding are in place to address these issues. Property managers and homeowners’ associations (HOAs) should be diligent in maintaining storm drains, retention ponds and the pipes that connect to our canals to help manage and mitigate these challenges. Regularly the entire system needs to be checked and examined to check for vulnerabilities. Here is a list of recommendations that should frequently arise
- Clear debris, sediment, or trash out of all pipes, inlets, and culverts. Keep grates clear and remove obstructions.
- Keep grass areas and swales mowed regularly. Prevent any deposits of yard clippings or related vegetation and waste to prevent filling in overtime.
- Check canals and ditches for any signs of erosion and stabilize the areas with plantings or sod. Regularly compare the original design with the existing dimensions and slopes to monitor and address any changes.
- Maintain wet ponds and lakes by removing trash, dead vegetation, and debris. Inspect outfall pipes to make sure they’re clear and open. Repair washouts or eroded areas with sod or vegetation.
- Routinely inspect any other outfall structures and weir, looking for signs of obstruction or damage that needs to be cleared or repaired. Remove vegetation or trash.
- Have the culverts professionally inspected for root corrosion and other signs of failure.
