Select Committee on Crossrail Bill Minutes of Evidence


Examination of Witnesses (Questions 17480 - 17499)

  17480. The information that they have presented us with, I would say, has been biased in favour of their proposals. We are also now having to deal with documents that I would say should have been available to us before the Bill was presented. Nearly every week we get something else that we need to wade through and work out whether it has implications for us. All this should have been available well before, and I am sure you will appreciate that whilst Crossrail and our local council and others have lots and lots of technical support available to them and a good deal of money, we have to do this in our own time and take time out of our lives and time off work in order to appear before you.

  17481. I mentioned earlier some of the language that they have been using. They talk about temporary impacts and they describe the permanent impacts as "residual". I do not know about you but "permanent" sounds a lot more serious than "residual". They also talk about significant impacts being somewhat limited but they have not described how they define what a "significant impact" is versus a not significant impact. You also heard from counsel earlier what it was "necessary" to do. I would like to suggest it is for the Select Committee to determine what is "necessary" and that what Crossrail is telling you is what they propose. Also, of course, their proposals impose huge negative impacts on existing sites, owners and users for a projected benefit that is as yet uncertain and unfunded.

  17482. I also ought to mention that counsel talked about who the Fairfield Conservation Area represent; we represent all the residents living in the conservation area, and, as I have said, in due course that is expected to be 3,000 properties.

  17483. There has been talk about how long we will have to put up with Crossrail. The sewer diversion, as proposed, is expected to last 22 months, then seven years for the Crossrail development itself and then Crossrail itself for ever more. The Crossrail tunnels, the route was largely presented to us as a given and if you look at the area and think, "Why have they chosen the route they have chosen? Why haven't they tended to have a lesser effect on domestic properties and a greater effect on commercial properties?", it is almost as if they have targeted domestic properties over commercial properties.

  17484. There is this obsession with being at the surface at Pudding Mill Lane Station. Quite honestly, no one knew anything about Pudding Mill Lane Station until its association with Crossrail. Crossrail have not been able to tell us how many people actually use Pudding Mill Lane Station at the moment, but it is very few. What I would like to do is put up a view of the Pudding Mill Lane portal.[23] This slide is not, for some reason, running north to south. The A12 which runs roughly north to south runs along there and the proposed Crossrail tunnels are running this way, west to east, and this is Pudding Mill Lane Station here. Because, they say, the track of Crossrail needs to be at the surface at Pudding Mill Lane, therefore, that is the justification for the depth of tunnels that they propose in this area and they are proposing tunnels as shallow as 11 metres in this area here.


  17485. In the next slide, this is a mock-up of what the tunnel will look like underneath 1 Baldock Street underneath which it is proposed to travel and that is to scale.[24] That house is 5.84 metres wide and the internal diameter Crossrail propose is 6 metres. Now, that is the internal diameter. The external diameter is wider than that and I understand that even today Crossrail cannot tell us precisely what the external diameter will be. They are certainly indicating a further 0.7 of a metre and it may be wider than that, and obviously it may vary according to site circumstances.


  17486. Clearly there will also be dust and dirt from the portals as the development gets under way. There will be noise, vibration and the risk of subsidence and inevitably there will be impacts on the quality of life.

  17487. Now, all of this has been presented to us as an absolute, but I seem to recall only recently that end-to-end tunnelling was non-negotiable, that they could not possibly do it, yet now they are doing it, so I would suggest that reasonable and responsible variations here too are also legitimate.

  17488. The extent of the impact on Fairfield Conservation Area is in direct proportion to the depth of the tunnels and the area. As I said, I believe it targets domestic properties over commercial properties. It pays scant regard to the ground conditions and levels. You will recall the plan of the Conservation Area which you saw earlier. There is a fall of a number of metres from north to south and another fall of a number of metres from east to west in the Conservation Area and the land immediately behind this property which backs on to the A12 falls by 2 metres, so there is a substantial change in levels in the area and yet the tunnels will be rising at their maximum gradient, so Crossrail propose.

  17489. It is also difficult to establish what the full extent of the impact will be because the designs are still under way.[25] Crossrail, in their proposals, have used pre-existing guidelines, such as noise levels as a justification. It is okay to make a load of noise in the Conservation Area because it is already subject to considerable noise from the A11 and the A12. Well, that sort of argument suggests that a brass band makes no more noise than a single trombone. What is fundamentally reasonable and responsible just has not been considered. That is astonishing, that difference in height between somebody's domestic property and the newly built tunnel. It would be different if a new developer decided, "Okay, we'll take the risk of building over a pre-existing tunnel and we'll build accordingly", but that simply is not the case here because these domestic properties, circa 1900, they have negligible foundations. All the more recent developments in the area, including the ones at the bottom of Baldock Street which are circa 1993/94, they have very substantial foundations. Numbers 27 to 69 Baldock Street have 25-metre pile foundations. Their pile foundations would progress through the whole of that tunnel to double that height elevation and that is why Crossrail have avoided those sorts of development in favour of circa 1900 domestic properties.


  17490. Then of course Crossrail's proposals go on to create further engineering problems which themselves have to be resolved and that is how we get to the proposed sewer diversion. Crossrail say they have looked at a number of options and the proposal they have come up with is the least worse. What they are proposing is a further tunnel travelling under the same area as is already substantially affected by Crossrail at a depth of 8 to 12 metres. Now, somehow or other they are going to have to make sure that the Crossrail tunnels just manage to skim underneath the sewer diversion that they propose will be pre-existing by this point, but if they were going at a reasonable and responsible depth, it would simply not be necessary to divert the sewer at all and all of the negative impacts of the sewer diversion would go and the majority of the negative impacts associated with Crossrail's own tunnels and operations would also go. The sewer diversion over and above the Crossrail proposals impose multiple worksites, and you have seen all the worksites.

  17491. Then security provisions—they are proposing that some of the sites will have 24-hour security, of necessity, they will have telecommunications connections, they will have lighting, and the other sites will be patrolled so that there will be access and egress. The area is going to look like it is part of the night-time economy. From what we understand from their proposals, the majority of the noise mitigation is associated with daytime, not night-time, works and yet they propose six months of night-time working for which they propose little, or no, noise mitigation. There will be associated lorry movements and there will be loss of parking so that substantial vehicles can get along the narrow streets which you have seen, and there will be temporary use and permanent loss of a proportion of the park, and you have already heard about the value of the park. There will be a permanent impact on the park and some of that impact just cannot be quantified because it is about the statement of worth that digging up the people's park makes to people who use the park and to people who know of the park.

  17492. In relation to the park, Tower Hamlets has an Open Space Strategy. It has recently introduced it and it has identified that there is already a substantial under-provision of public open space. Let's face it, were it not for Victoria Park, which you saw, and Mile End Park, another large park slightly off the map to the west, then the relationship of residents to park space would be even less. There are also EU guidelines which aim to safeguard, and increase, the existing provision, and the Mayor of London has defined as one of his 100 public spaces Grove Hall Park. For many, the park is in lieu of usable back gardens, which you have already heard. What you have not heard is that we have been in discussion with the Council and with Leaside Regeneration about improving the park and dealing with some of the balancing act that needs to take place about the level of use and how different types of use need to be accommodated. That funding of, and proceeding with, those improvements is now in question.

  17493. Crossrail have made great play in our discussions a week or so ago with them about the lack of availability of a worked-up design for the park. Well, there is not a completed design for the park, but there has been substantial consultation, although a lot of that work has been put on the back burner because of Crossrail's proposals and, let's be honest, Crossrail have not got a completed design for anything either. Clearly there will be safety implications because what Crossrail are currently proposing is that they have shared use of the park while the works are under way.

  17494. If we can have the next slide please, you have seen this one before, what they are proposing is that they will bring vehicles in and out, but they do not know how many vehicles yet, they are not entirely sure, and that will be under way while the park is in use.[26] Clearly that little child we saw earlier will not be able to run around willy-nilly with lorries coming in and out of the park. I suspect that his parents will not even be inclined to visit the park because it will essentially be a worksite. What Crossrail say is that they will have a banksman who will undertake traffic control, I suppose. We cannot even understand why there has not even been an effective dialogue between Crossrail, Tower Hamlets and Leaside Regeneration about all these issues and how, we would say, if the other proposals proceed, never mind the sewer diversion, there should be some benefit to the local area and that benefit could best be vested in the park.


  17495. Crossrail have presented to you their worksites, and perhaps I could have slide 23 please.[27] We have also been in discussion with Crossrail about the impact of this worksite on a regularly used pedestrian and cycle access along here which will take you into the park and down to Tesco's, which is just off the map, and again it seems a comparatively safe route, a predominantly traffic-free route. Crossrail's original proposals were that they would simply block it off for 22 months and pedestrians and cyclists could use what they call `an alternative route', an alternative route over here, a pre-existing route which they would otherwise choose not to use. We have been in discussion with Crossrail and they have modified their proposals. They are now saying that there will be occasions, they believe, when pedestrian and cycle access has to be completely prevented, but for much less than 22 months and they are now suggesting a month or so. They say, "We cannot commit that such closures will not happen. However, we will use all reasonable endeavours to keep Brick Lane open to pedestrians. In reality, we believe there will be a requirement to close this road to pedestrians for approximately one month". We consider that it should be possible in this day and age to avoid any closure whatsoever.


  17496. I should have mentioned, in relation to the park, Tower Hamlets' presentation yesterday which members of the Committee may recall, but I think it is useful to emphasise exactly the point that Tower Hamlets were making in relation to a shaft in the park. Tower Hamlets accepted that very considerable weight will, of necessity, be given to health and safety issues, but they also recognise that the proposals for the sewer do not just relate to safety access, but they also relate to repair and maintenance and that there is concern about settlement associated with the sewer diversion as a consequence of constructing the Crossrail tunnels themselves.

  17497. If we could go to slide 28 please, Crossrail have presented to you what they think is the least worse or the best option, depending on what language you prefer to use, but if the Committee determines that there should be a sewer diversion, then a better alternative that myself and colleagues just worked out by looking at a map would have no negative impact on the park at all.[28] Gone would be the worksite in the park and any necessity for the access and mitigation and all the rest of it. Instead, there would be an access shaft at the bottom of what is currently a vacant, derelict site, 212 Bow Road, and a further access, also currently a derelict site, but one of the sites that is subject to planning permission which Crossrail tell us they are already in discussion with about these deep pile foundations which either they propose the developer would deal with, depending on timing, or Crossrail would need access to the land to deal with themselves. Now, that proposal with two access shafts gives you a shorter maximum length between tunnels, it gives you two interim access points instead of one and it does away with the need for any negative impact on the park. If it was determined that it was necessary, depending on how this site was subsequently developed, that there needed to be a gate access from the park to the access point for the purposes of safety, I can see no difficulty in that.


  17498. You have also heard talk of the impact on the Manhattan Building and that impact is in fact very, very substantial to the extent that Crossrail are proposing that 28 of the properties may well qualify for temporary rehousing for a period of 15 weeks. The residents will also lose total access to the car park for three nights as well as suffer serious inconvenience throughout the construction period. I have brought with me a petition signed by a number of residents of the Manhattan Building which I would like to make available to the Committee.

  17499. I am sure that, previous to this, there has been a great deal of discussion about noise and vibration. Crossrail have indicated that residents living above the tunnels will hear the trains as they travel through and I bet that somebody living above a tunnel that is only 11 metres below their property will be substantially disrupted. It is also worth noting that when representatives of Metronet appeared before the GLA Transport Committee, Keith Clark of Metronet said, "Anyone who has been to the theatre in London knows that you can hear the Tube in most London theatres", and then went on to say, "and also feel it". Now, Crossrail have not quantified the extent to which the tunnelling or the use of the tunnels will be heard and felt by residents in the area, but I would suggest that it is substantial and it is in direct proportion not just to the depth of the tunnels, but to the extent of their subsequent use. Below-ground noise and vibration may also be expected to affect residents neighbouring the terraced properties, but Crossrail seems to have been fixated on only those residents who live directly above the proposed tunnels. Now, I am not a technical expert, but I know that if you drop a stone in a pond, the ripples radiate outwards right to the edge and if it is a substantial splosh, then the ripples work their way backwards as well. The terraced properties in this area are bound together; their support is not by virtue of substantial foundations, but by virtue of the fact that they are leaning against each other.
