TGD M 2010 – 3.1.2.3 – Gently sloped access route

3.1.2.3 Gently sloped access route Where site gradients do not allow a level access route, the flattest gradient achievable should be used. Access routes of 1:20 or less steep are preferred. For the purpose of this guidance document a gradient steeper than 1:50 (but less steep than 1:20) is considered to be gently sloped
