The following amendments have been made after taking into consideration the local Villager Representatives's comments
(a)
the scope of works at Pak Kong River reduced from full scale training to removal of two bottleneck;
(b)
re-provide the overflow weir at Ho Chung Channel
Key Outcomes:
Environmental Friendly Design
(a)
The masonry and grasscrete lining was revised to gabion lining with planting pits to retain the river ecology, and to improve the aesthetic, vision and environmental aspect of the river widening works.
(b)
Natural substrates, pools and riffles will be provided at the riverbed so as to restore and enhance the ecological habitat in the originally river channel.
(c)
Fish-ladder will be provided at the downstream side of the weirs.
(d)
Since there were many village houses adjacent to the concerned river section, the structural stability of these houses is the major concern. As such, a remaining wall would be provided behind the gabion walls.
