Peter A few more points for you to raise with DfT 1. We have quite a few crossings with old stone kerbs, which not flat. Also it is very difficult to lay a surface to 6 mm, especially if laid by hand. How many reading should be taken along the length of dropped kerbs and at what spacing? How many readings above 6 mm will be allowed, if any? 2. The guidance notes recommend a 150 mm border around red tactile surfaces, when there is a lack of contrast with surroundings. Does this apply to conservation areas where the tactile surface is not red?
