Several factors contribute to standing water in drainage ditches. All drainage ditches throughout the Town connect to either the ocean or the sound and therefore are impacted by tidal influence and subject to inflow and outflow of water. The water table in the coastal environment can be extremely shallow or close to the land surface. Open drainage ditches can be several deep and intersect the shallow water table and the continued presence of water. Precipitation, surface runoff and resultant drainage flows can also impact water surface levels observed in open drainage ditches.
