I take it you managed to get the site cleared - well done! Did you have your BBQ?
Paths between plots on our site must be an absolute minimum of 18" wide.
If you want to be DDA compliant, here's some info:
Route wide enough for wheelchair access – minimum 1000mm width
Gradients:
• Ramps/Paths 2m or less can have a gradient of (1in12).
• Ramps/Paths 2m – 5m, gradient of (1in15).
• Ramps/Paths 5m or more, gradient of (1in20).
• Car Parking Spaces, gradient (1in50 )max.
Hope this helps.
