I am attempting to pull a technical issue out of the he said / she said going on on the Executioner thread (which I think I triggered, but what the hell!). Lets see if we can keep this discussion strictly on the technical side.
Thanks for pulling this legitimate question out of that quagmire. I'll try and address your questions below.
The issue is: new trail sections and bypasses seem to be being built wider than necessary.
A solid trail base is necessary to handle the large numbers of riders we have on the Shore. Building the trail base approximately 1 meter (or three feet) wide is a best practice. For a number of reasons (weather conditions, rider ability, rider error) all riders may not stick to that "narrow ribbon", and the 1 meter wide trail base ensures long term stability of the trail.
I don't think this is the intent, but rather a byproduct of big trail day crews where we are instructed to work side by side and cut new lines with rakes. By working perpendicular to the line, the trail width tends to end up 3 feet wide, I think because of human factors.
Making trails wider than needed is a waste of work and materials, and takes away more frog habitat. So, why not start working parallel to the intended line rather than perpendicular? The result might be trails that are 1/2 the width, twice as fast to build, and which will need half the maintenance. And which resemble singletrack moreso than municipal-standard park paths.
Thoughts?
Working side by side is much more efficient for any sized work crew than working parallel to the trail. Think of an assembly line.
While a narrower trail may be faster to build, I disagree that it will be less maintenance. The trail bed will not be stable, riders will track off the line, the inside edge will sluff onto the trail, the outside edge will sluff away, etc. The extra effort to construct it properly the first time pays off in the long run.
If you are concerned about the appearance of a 1 meter wide trail, please remember that the trail has just been constructed. It's like a new lawn where the grass is just starting to take seed. Wait a year or two, and that ribbon of single-track that we find desirable will most likely appear.
