The following watercourses and wetlands were observed:
Chetwynd Loop
WC 50 –KP 25+492
WC 51 –KP 25+515
WC 52 Stone Creek KP 25+556- Company representatives indicated the crossing is planned to be completed by mid or end of March. The area is heavily disturbed from previous flood events. A larger section of the riparian area was cleared than required for construction activities.
WC 40 KP 19+047
WC 39 KP 18+979 Bissett Creek - Company representatives indicated the crossing is planned to be completed by mid or end of March.
WC 30 Tributary to Pine River KP 16+700 –Completed 20 February 2021
WC 29 Wildmare Creek KP 15+219 -Crossing complete.
WC 28 KP 14+500 –Landowner excavated a trench across the RoW prior to construction.
WC 25 13+967 NCD -No break in topsoil for potential water to flow across RoW. Company representative stated they would remove some soil. An opening in the trench spoil was made and photographic evidence was provided on 6 March 2021.
WC 26 KP 14+028 NCD
WC 22 KP 13+186
WC 15 KP 9+442 NCD
WC 11 KP 8+416
WC 10 KP 8+391
WC 7 KP 6+564
WC 6 KP 6+009
L2s Tributary to Centurion Creek KP 1+271 –The riparian area was machine cleared and grubbed up to approximately 10 m from the edge of the bank (See NNC #3). The temporary bridge required cleaning and repairs to wrap the geotextile around the bottom of the travel planking on the bridge (See NNC #1).
L1 Centurion Creek KP 0+806 –Watercourse was cleared and grubbed to the edge of the bank on the west side (See NNC #2 and #3). The crossing was originally scheduled to be open cut but company representatives are in the process of obtaining approval to bore the crossing instead. They indicated the banks are prone to erosion as seen on other projects. A crew was pre-grading the slope for the trackbore to set up. The RoW was narrowed at the watercourse crossing by approximately 20 m.
WL 14 KP 0+806
WL 6 KP 0+321
WL-20

Aitken Loop
WC 12 KP 6+835 Blueberry Creek –Sediment fencing and straw wattles were installed in the riparian area and company representatives indicated diversion berms would be in place within the next two weeks. Topsoil was crowned for settlement. The bridge was muddy and the wingwall was not connected properly (See NNC #1). Log steaks and coconut matting were placed to stabilize the riparian area and company representatives stated the banks would be seeded during final reclamation. Clearing was narrowed down in the riparian area.
WC 17 KP 7+802 –Erosion control measures were in place and company representatives indicated the subsoil pile would be spread out after the temporary bridge was removed. They also stated the right-of-way is shared with another company and the area was cleared prior to construction. The height of the wingwall and sides of the bridges were not high enough to prevent sediment from entering into the watercourse and riparian area (NNC #1).
WC 16 KP 7+687 –Log cribbing, sediment fence, coconut matting and rocks were installed for erosion and sediment control. Diversion berms were also added tying in the north and south right-of-way. The wingwall at the approach requires repair to prevent sediment from entering into the watercourse (NNC #1).
WC 15 KP7+602 –Erosion and sediment controls were in place at this very shallow channel.

2 March 2021
Chetwynd Loop:

WC 30 Tributary to Pine River KP 16+700 – Bridge deck requires cleaning and daily maintenance. The bridge wingwall was not installed high enough to prevent sediment form entering the watercourse and riparian area.  
WC 29 Wildmare Creek KP 15+219 – Bridge deck requires cleaning and daily maintenance.The bridge wingwall was not installed high enough to prevent sediment form entering the watercourse and riparian area. Geotech cloth on edge of bridge has small holes.
WC 10 KP 8+391– Sediment and erosion control was not adequate to prevent sediment from entering the watercourse.
WC 7 KP 6+564– Bridge deck requires cleaning and daily maintenance.The bridge wingwall was not installed high enough to prevent sediment form entering the watercourse and riparian area. 
 
3 March 2021
L2s Tributary to Centurion Creek KP 1+271 – Geotech cloth was missing under the planks of the bridge to prevent sediment from reaching the watercourse.
WC 51 –KP 25+515, WC 39 KP 18+979 Bissett Creek and WC 40 KP 19+047  –Geotech cloth was missing under the planks of the bridge and the wingwall was not installed high enough to prevent sediment form entering the watercourse and riparian area.  

4 March 2021
Aitken Creek Loop:

At WC 12 KP 6+835 Blueberry Creek – A break in the wingwall was observed where sediment from the muddy bridge could enter the watercourse. The height of the geotextile fabric was not sufficient to hold sediment back from entering the watercourse.
WC 17 KP 7+802 – The bridge wingwall was not installed high enough to prevent sediment form entering the watercourse and riparian area.  General repair and maintenance is also required.
WC 16 KP 7+687- Wingwall on the west side of the bridge requires repair at the approach.
