I think the 1999 Guidance is fairly clear on these issues. The drop kerb diagram (Figure 1c p14) states that flush is the "Preferred carriageway surface level" and the " Minimum carriageway surface level" is "Not greater than 6mm" below. So you would need to try and lay stone kerbs flush and if any part was more than 6mm higher then it would not be compliant. This doesn't look good for Sheffield's compromise agreement with our disability group for a 12/13mm upstand - we will drop to 0%. In a number of places the guidance refers to the need to provide the wide band if the tactile paving colour doesn't contrast sufficiently with the footway colour - so that would still apply if you chose a non-red conservation area tactile colour which is too close to your footway colour. -----Original Message----- From: Wheatley,Graham (Environmental Services) [mailto:Graham.Wheatley@xxxxxxxxxxxxxxxxx] Sent: 09 July 2002 12:34 To: 'tcug@xxxxxxxxxxxxx' Subject: [TCUG] BV 165 Submission 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?
