re: Muddy alley between houses - Advice Needed

Had this issue at a previous house. Installed a drain which ran I ran to the front yard, then filled in the area with pea gravel, and put some 1x1 paving stones for a walkway. Mine was only about 30x5 area. Looked good enough and worked well while only costing a few hundred dollars and an afternoon of work for my dad and I.
