The main line of the Naheno Park trail is a 'recognised trail' and is protected by a statutory public access right of way on the SFU land title. The SROW can be moved or removed, but the goal is to protect the right for a multi-use trail through that part of the forest with a crossing of the Ringroad at the point of best sitelines. If there were to be future development that jeopardised the trail, then given the status of the SROW, it is likley that the local community would be consulted to discuss the compensation and replacement/alteration routing of the trail.
As for Lower Gear Jammer, the massive holes between the 2 bridges on the second corner have been repaired. About 40 flat stones, packed with good draining soils. Will likely settle in over the next couple weeks of rain, but then a "topping up" and it'll be solid. Good first step to fixing a complete sh!t-hole.
The piece after the second bridge is still too wet and next week a proper drainage trench will be installed and then the holes fixed. For now it's just filled in to keep the flow.
