111 Part of the plaintiffs' works proposals for the western area, identified under component B(b) of the minute of declaration, relates to the potential construction of one or more culverts in this area. A good deal of evidence and photographs were adduced in the latter stages of the trial on the subject of culverts. In the end, my assessment is that such evidence was of only marginal utility. The purpose of a culvert pipe running under a road, is to convey any accumulating water from one side of the road to the other, and so thereby to prevent a pooling or flooding problem that may eventually affect the integrity of the road. In the course of Mr Oreo's cross-examination on Friday afternoon, 7 May (day 6 of the trial), the first reference was made to a seemingly dysfunctional (buried) culvert located at between the 3.56 m mark along match line CC and the 3.72 m mark - being the next width measurement to the east of match line CC in the exhibit 13 survey. I use the word 'dysfunctional', since it is apparent from photographs taken that a concrete culvert pipe running north to south under the carriageway at this point was significantly obstructed by dirt, debris and leaves and so could not be functional as a culvert (see exhibit 38, photographs SGO 36, SGO 37, SGO 39, SGO 40, SGO 41; exhibits 31B, 31C, 31D, 31E, 31F, 31H).
