Pollution

Introduction:

One of the concerns about the proposed Tfl estate project by the underground station, in the centre of Northwood, is the effect on pollution levels in the centre of the town if the Tfl Proposal is built.

One main component of pollution is that arising, not surprisingly, from vehicle traffic.

The pollution experts monitor many aspects of this kind of pollution but two of the most prominent concerns have to do with the levels of Nitrogen Dioxide and the levels of various sizes of particulates in the air we all breathe.

In order to establish the existing levels of pollution Northwood’s Voice has arranged, with Hillingdon Council’s permission, for the monitoring of one aspect of this pollution – namely Nitrogen Dioxide.

Northwood’s Voice has been working with an environmental company used from time to time by Hillingdon Council and we have, at our own cost, sourced their equipment for our monitoring exercise.

Further, this environmental company analyses the findings and reports back to us.

Existing Situation:

As everyone in Northwood is only too well aware, the introduction of a set of traffic lights in Green Lane a number of years ago, adjacent to the Tfl underground station has caused considerable traffic delays through Northwood – and almost certainly raised the traffic pollution levels in the air along Green Lane as a result.

Northwood’s Voice are not aware of any pollution studies having been carried out before and after these traffic lights were introduced. Similarly, a mini-roundabout was introduced in Green Lane – very near to the traffic lights and once again may well have raised traffic pollution levels in Green Lane and in the centre of our town.

To some extent the Tfl underground station is already an area of much concentration of vehicle traffic – the traffic light junction by the underground station is already used routinely by buses, taxis and commuter parking traffic using the Tfl car park at the bottom of Station Approach.

The future effect of Tfl proposals on pollution levels:

Whilst Northwood’s Voice has been able to measure Nitrogen Dioxide pollution this year, we can expect the levels to increase in the future – even if no further property developments are approved by Hillingdon Council.

Extra set of traffic lights in Green Lane:

The sketches which Tfl have revealed to-date of their proposals to handle traffic arising from their property development project in the centre of our town are seemingly lacking in some detail, but people have been advised that another set of traffic lights will be introduced just 50 yards or so along Green Lane from the existing set of traffic lights outside the underground station.

This new set of traffic lights is seen as necessary in order to allow traffic to enter the new Tfl proposed estate down a much widened Central Way (currently a footpath between “Taylor Made” and “Lee Gardens” shops in Green Lane).

Northwood’s Voice understands that Central Way is owned by Hillingdon Council, not Tfl, and thus Hillingdon Council themselves will be very influential in approvals for this widening and thus the viability of the Tfl proposals.

Thus in a very short distance past the underground station, of maybe 100 yards or so, Green Lane will have two sets of traffic lights and a mini-roundabout to contend with.

A traffic situation that is already very difficult for Northwood residents is likely to become much worse – and of course there will be an effect on traffic pollution which is not likely to be favourable.

Click and collect traffic:

Tfl has been introducing a variety of schemes at numerous other underground stations around their network involving “click-and-collect” facilities.

The following statement has been taken from the Tfl website  “Our Click and Collect partnership with the retailers has been a tremendous success for all involved, and we are delighted to be expanding the service to more locations, making it easier for more customers to order their goods and conveniently collect them at their chosen station.” 

Tfl have (perhaps conveniently) not said yet whether they plan to roll out this “tremendous success” to Northwood and, if so, the level of additional traffic and traffic pollution that we might expect in Green Lane.

Property development:

Up to 500 additional people may be expected to live in the proposed 4/5 floor flat and housing development by the Tfl underground station.

There will thus be a large number of additional cars (and delivery vans) coming and going  – and once again the effect of this additional traffic on air traffic pollution in Green Lane is not likely to be favourable.

Future Building in Northwood:

As we speak there is yet more and more large scale property development (including many flats) taking place in Northwood and as these properties are not yet occupied we have not yet felt the effect that the future cars arising from all this current property development will have on future levels of traffic congestion and pollution along Green Lane as these people travel about.

For example, most Northwood residents will be familiar with the new (yet to be completed) “Pinnacle” development now standing on the site of the former Reindeer Public House.

This development has 12 flats and an equivalent number of parking spaces – right in the heart of our town, adjacent to Green Lane itself.

Further down Green Lane another new property development is currently underway at The School of Theology (“Bible College”) which also involves 12 flats and also with associated parking.

Just a little further away the long line of large new blocks of flats along Ducks Hill Road is presently being added to yet again.

The latest block, presently under construction, will have 10 flats and associated parking – and once again will further add to Northwood traffic congestion and traffic pollution.

There are numerous other examples but this portrays a reasonable picture of the sort of future traffic congestion and future traffic pollution that has been approved and has yet to hit us – even without any of the latest Tfl proposal for more than 100 flats and houses by the underground station.
