HENDERSON, Nev. - A viewer says he has seen water build-up near Arroyo Grande Boulevard and Warm Springs Road. He says the water has been there every day for a year.
Henderson residents have long experienced standing groundwater issues in this area.
The groundwater table is shallow in parts of Henderson, causing water to bubble. It escapes around pipes, valves and covers and breaks the surface. It may appear to be a water leak, but it's groundwater. The groundwater becomes more prevalent in the summer with increased irrigation and the monsoon season.
Henderson officials want to ensure the water doesn't cause a sinkhole, so they've opened the street to inspect water lines and valves. They found no leaks, no undercutting and no sinkhole developing. They have taken dozens of samples to verify it's just groundwater.
The city also hired a geotechnical engineering firm to find why this groundwater is so consistent. Once these engineers weigh in, the city will either replace the road's sub-base material or install a French drain. That involves pipes with holes on the top, so ground water collects in the pipe, diverting the water to a downstream location such as Pittman Wash.
