As per mapnote I placed to the west, on the "middle" roundabout Cranbrook access; turning in to here there is no speed limit sign so in law you're perfectly entitled to do 40 mph through this estate (if you're feeling suicidal!). I expect the situation with Cranbrook will be writ here, too - council going for urban limit 30mph and residents agitating for 20mph. Given the tightness of the street layout it's not sensible/viable to go at more than 20mph so have tagged for maxspeed=20mph in anticipation of logical sense prevailing. Local mappers should monitor progress and update when it is settled. I've searched online for Traffic Orders setting the limit but drawn a blank for this development.
