My apologies! I was rushing to get this bb done and made some assumptions that I should have gotten clarification on. I also should have described my process, especially since I appear to be the first one to try for this bb.
When I read "60 foot long', I assumed an equivalent amount of square footage based on standard minimum widths x lengths for driveways and pathways would work as well. If there is a reason that a driveway or walkway must always be 60' or longer, then I don't understand this bb and I will just move on to a different one.
Otherwise, please read on:
When surveying my drive and path, I did a quick visual estimate using my preset markers (explained below) but I will do the math and actually reference professional guidelines below:
* LandscapingNetwork.com is an independent resource for information about the landscaping industry.
Using guidelines from the LandscapingNetwork.com website, the minimum width of a foot path is 18". For our purposes, I will round that up to 24" to keep the math very simple. Also, because I am not just shoveling strolling paths through a garden, but functional, paved access paths to a house. 18" is not enough room to actually be functional (IMHO).
Minimum for a driveway/parking spot/single car turn-around is 10' x 20'.
Applying those width measurements to the badge bit requirements, minimum total square footage with 60' of length would be 720sqft.
My driveway measured at it's smallest width and length is 24'x40' (widening at the street- more on that later). My walkway is almost 3' when shoveled out. So let's be conservative and just say 2'x18'. That's a total of 996sqft.
So in terms of total square footage covered, that shouldn't be a problem.
I will go further:
Again, being mindful of accessibility, the path markers on our drive and path are not random. They are spaced a minimum of 10' apart going lengthwise to the street (see additional pics). They are set 25' across the width of the driveway except at the street entrance where they are set 28' apart. The little extra width at the street helps for turning and visibility. The street plows do try to respect those guide markers and try not to plow us back in. But we are on a corner lot, and for a snow-load like yesterday (over 2'), we inevitably got plowed back in. The markers help me cut the snow back to keep the driveway open.
These markers are also to prevent 'shoveling drift' as I call it: the tendency for a path to become smaller and smaller the longer you shovel. I make a point to shovel past these markers every time to make sure we always have enough room to park side by side and comfortably open doors, walk around, etc.
Same goes for the foot path leading to the house. The 3' wide path has a slightly raised edge on each side. By shoveling all the way to that raised edge, it ensures that the pathway stays open and accessible.
I hope that clarifies my process. Thanks for your consideration.
