The structure has deteriorated and is probably susceptible to infiltration and inflow. Some root intrusion is also observed. In addition, the existing access cover is not secure, thus allowing possible entry of foreign matter. The actual potential of flooding of the structure is uncertain. A flood level profile has not been determined for this area.
Field observations indicate that the spring box has never been inundated by flood waters.
However, observation indicates that floodwaters have approached the top of the spring box. In any case, it is reasonable to conclude that the existing spring box could be susceptible to inflow from a significant flood event. It is proposed that the integrity of the existing spring box be improved by encapsulating the existing box, raising the top elevation, and making the potential entry way watertight. The existing top would probably be removed to improve access and eliminate an unwanted cavity. The new wall would be anchored to and founded on the underlying bedrock and sealed as appropriate.
