Bristol Site

I suppose it will depend on the relative levels of the two sites. I don't remember BW ever flooding. That pub down by the basin lock gates has got wet occasionally and the water level was into that cross street from the swing bridge one year.

But is it a proper one or an awkward to access manhole cover?

Just the road collapsed not far from the gate.

 Just done a calcualtion regarding how long it would take a vehicle coming round the corner to reach the entrance. At 30 m.ph. 18 secs, at 40 m.p.h 8 secs. In the opposite direction the time for a sighted vehicle at 120m away to reach the entrance is even less, at 30 m.p.h 15 secs and at 40 m.p.h 6.5 secs  For safety, and for application approval, it would appear to me some kind of traffic calming measures would need to be put in place. Hope my calculations are wrong!

just an after thought, perhaps stopping distances are more relevent. At 40 m.p.h its 40 yards so in theory the majority of vehicles should be able to stop for anyone exiting the site. I have always found rumble strips very effective at slowing myself down.

As I understand it, the plans to ban diesel vehicles from the inner city will come into effect in 2021. The ban is supposed to last from 7.00am until 3.00pm.

So how will departure from site will managed in this time scale? Stay until 3.00pm, no arrivals until 4.00pm? No using the vehicle to leave the site during most of the day?

Or go out south via the m5 which does not go in to the city centre

It looks as though the proposed site sits just outside the zone, although leaving heading South might just take you in then out of the medium zone🤔 Not sure if I am looking at a map that has been agreed upon though.....

Hope my calculations are wrong!

They are! No idea of the distances you are using (around 240 metres?) but at 40 instead of 30 it will take 3 quarters of the time. 

As an ex highway engineer:

For a junction onto a 30mph limit the required visibility distance is 43m (y distance) from a point 2.4m behind the edge of carriageway measured down the access. This will define the needed visibility splay etc. Double white line systems make splays less onerous to the left on exit. At 40mph the y distance is 120m.

From my understanding it is not in the red Zone, nor the Clean Air zone, and privately owned diesels are not charged for entering the Clean Air zone which gives more access/exit  routes from the East and South other than the main access/exit route from the Gordano turn off....... unless they change it again.
