Good steps help people walk safely up steeper slopes, but they are a barrier to several types of users. Therefore, they are only for use in exceptional situations where the terrain naturally restricts access, and a ramped path cannot reasonably be provided without exceeding ramp gradient limits of 1:12.

Any land is eligible.

The steps must be part of a new or upgraded path.

  • vertical timber board risers, fixed in place with half-round timber stakes
  • step treads back-filled with well-rammed Type 1 granular sub-base
  • surfaced with 10 millimetres of whinstone or granite dust
  • all timber to be treated
  • steps to be level and evenly spaced
  • width of steps to extend 150 millimetres either side of path width
  • height of risers is no more than 150 millimetres
  • edges of treads to be dressed off using soil material, compacted and allowed to seed
  • paint treads of steps with non-slip surface paint to manufacturer’s recommendations

You can claim £150 per linear metre.
