Camden Updates Basement policy

The Camden Local Plan 2017 includes policy A5 on basement development which updates and expands former basement policies. It places specific restrictions on the scale of basements and their impact. You can object and the Basement Impact Assessment is a good place to start.


Where the proposed development includes a new or extended basement a detailed technical statement must be submitted by the applicant assessing the impact of the development on drainage, flooding, groundwater conditions and structural stability. This information should be contained within a Basement Impact Assessment (BIA) which is specific to site and proposal.

Updated guidance 2018

  • Planning Guidance:  On 26th March 2018 the Council formally adopted Camden Planning Guidance : Basements. The Guidance was prepared to support the policies in the Camden Local Plan 2017. It should be read in conjunction with the relevant policies in the Local Plan. The Guidance replaces Camden Planning Guidance 4: Basements and Lightwells (July 2015).
  • Audit review: Basement Impact Assessments are technical documents which must be prepared in accordance with planning policies and guidance and submitted with planning applications for basement development. The Council obtains independent audits of BIAs from Campbell Reith Consulting Engineers in order to ensure that they meet the technical policy requirements.
  • Camden has produced a ‘BIA pro forma’ and a help note on ‘Defining the Scope of Engineering input to preparing BIAs’ in order to help applicants who are preparing planning applications for basement development.

The BIA will be submitted to an independant technical audit by Cambell Reith and covers the following details:

The soundness of :
a) the conceptual model with regards to ground and groundwater conditions
b) the consideration given to structural condition of neighbouring properties
c) identification of the likely impact on land stability and the structural integrity of the neighbouring properties
d) identification of the likely impact on hydrogeology
e) identification of the likely impact on hydrology
f) the scope of completed ground investigations with the presumption that invasive ground investigation should take place in all instances
g) appropriately conservative modelling used in reaching the BIA assumptions including anticipated structural damage categorised according to the Burland Scale, and conclusions (mindful that Campbell Reith shall use professional judgement in respect of calculations in the audit material and are not required to carry out any detailed calculations or checking of specific figures)
h) proposals for ongoing monitoring of groundwater levels
i) measures to ensure the on-going maintenance and upkeep of the basement and ground water management measures
j) temporary works methodologies, requirements and recommendations for construction contractors
k) the inter-compatibility of the assessments, findings and conclusions of all BIA
l) an outline methodology for monitoring and responding to ground water levels and structural movement
m) Identification of relevant cumulative impacts on land stability and local ground and surface water conditions arising from the basement development

Network Rail destroys West Hampstead Green Assets.


Trees removed by Network Rail September 2018

It is established in UK law, in the Town and Country Planning Act 1990 Section 198, that trees have value as a public amenity and therefore local planning authorities are given a duty to protect trees in the public interest.

CAVAT (Capital Asset Value for Amenity Trees)  is used by the London Tree Officers Association as an asset management tool for trees that are publicly owned, or of public importance, to express their value in monetary terms directly related to the public benefits that each particular tree provides – as if it were a financial asset of the community. Applied to the trees removed last week behind Sherriff Road – and many others are planned for destruction by Network Rail this month in other communities along the tracks as far as Wembley – we have lost thousands of pounds of green assets.

cavat2Network Rail explains: “We appreciate that cutting back vegetation can be a sensitive issue and therefore take great care when planning this type of work. Vegetation work on the railway near to your property however is necessary so that we can maintain and operate a safe and punctual railway. We remove trees that are tall enough to fall into the path of a train or onto critical railway infrastructure. We also look to remove problematic broad leaf species (such as ash and sycamore) that can have a detrimental effect on rail adhesion which can lead to safety related incidents and disrupted train travel. We did also undertake an ecological survey and environmental appraisal for the vegetation works, in line with best practice guidance to identify any protected habitats or species”

National Crisis

Guardian Exclusive: Plan to stop leaves and branches falling on lines has already led to thousands of trees being chopped down

Thousands of poplars, sycamores, limes, ash trees and horse chestnuts have already been chopped down across the country from Yorkshire to Dorset, and the scale of the potential destruction outlined in a Network Rail blueprint involves 10m trees growing within 60 metres of track.

Network Rail, the public body that owns and manages much of Britain’s railway infrastructure, disputes that millions of trees are at risk, and that its felling operation is secretive or represents a change in practice. After publication of this article, the organisation’s head of media, Kevin Groves, said in an email: “We are not a logging company or a paper making company – we have no need or desire to remove all the trees from the railway. Our job is to run trains, and run them reliably and safely and to do so we have to manage our lineside vegetation carefully and responsibly and that’s exactly what we do.” This enabled Network Rail “to both maintain and look after the trees on our estate, as well as remove dangerous ones and those minority of species that can cause reliability and safety problems in the autumn. Biodiversity matters to us.”

From Regulator – Office of Rail & Road (ORR) – Complaints about Network Rail

“Network Rail is responsible for the railway network. This includes:

  • line-side maintenance including vegetation and fencing
  • track quality
  • environmental issues such as noise and vibration, pollution and graffiti
  • railway structures such as bridges, station buildings, overhead lines, tunnels and signalling
  • network maintenance, particularly engineering work and speed restrictions
  • property issues including changes to use of railway land

You should try to resolve your complaint with Network Rail first.

We provide information on what Network Rail is responsible for and how you can make a complaint or enquiry. But Network Rail’s licence is designed so that our regulatory controls are at a high level, so we are unlikely to be able to intervene in many individual complaints.”

Over the last fortnight, people have woken to the sound of chainsaws and expressed concern at the lack of consultation and the scale of the destruction. Who are they to turn to? Who is holding Network Rail accountable?

All Aboard?

Due to engineering problems, the plans for the re- development of a new overground station in the centre of West Hampstead need to be modified.

The bridge under the existing station building is over 140 years old and owned by Network Rail. It’s in worse condition than previous structural assessments had indicated. A 30cm slab of concrete on top of the bridge adding to the loading was discovered and had not been not shown on any previous drawings or structural assessments. Network Rail and London Overground Engineers are in agreement that this concrete slab should not be removed as this is likely to further damage the bridge.

Removing the existing station building and providing a wider footway would result in a weak area of the bridge being exposed to accidental wheel loading which all bridges must now be designed to account for when there is a possibility of a large vehicle ending up on the bridge either intentionally or accidentally.

A scaled down modernised new station can be built with a modified design integrating the existing brick station entrance as a colonnade.

O:G station revised 1

Integrated colonnade proposal

Failing agreement (and there is some community dispute) the existing station entrance will be boarded up (below is an example not a replica) until resources close to £1 million are found  sometime in the future to repair or replace the bridge and provide for heavier loading at the front meeting required bridge safety standards. Network Rail’s funding plans are made for 5-6 years ahead and do not include this project.

WHGARA have requested a wide public consultation to ensure that ordinary residents and transport users have a voice in the necessary design compromise which will either blight or protect the centre of West Hampstead ‘village’.  Support us by commenting on this post.






Phones Still Aren’t Us

Outside Centra Wellington Place Panel (1)-1024x677
The application by Euro Payphone Limited (2017/5430/P) for an installation of a so-called ‘telephone kiosk’ (aka advertising display unit) at the corner of West End Lane and Iverson Road (and several others up WE Lane) in November 2017 – did not find favour with most local community organisations, NDF, WHAT, local councillors TFL and the Metropolitan Police all objected and the application was rejected by Camden (three cheers) . 
One of the reasons given for refusal of these  in the Delegated Report by Camden was the detrimental impact of siting such  obstructions in an area of high pedestrian volumes.
The footprint of the proposed telephone kiosk measures 1.32m by 1.11m.
Detailed design drawings that include the orientation and exact proposed positioning of the new telephone kiosk on the pavement have not been submitted and so it is unclear as to how wide the ‘clear footway’ width would be once the proposed telephone kiosk has been installed. However, Camden’s Streetscape Design
Manual section 4.01, together with TfL’s Pedestrian Comfort Guidance, states that street furniture should be placed a minimum of 0.45m back from the carriageway, therefore the proposal would result in the loss of a minimum of 1.8m of the footway.
This would reduce the ‘clear footway’to less than the minimum threshold, which would reduce pedestrian comfort, resulting in overcrowding, issues highway safety through interfering with signals, visual obstructions, visibility splays and may lead to the discouragement of sustainable travel. As such, the proposal would be contrary to Policies A1 and T1 of Camden’s Local Plan and Policy 9 of the Fortune Green and
West Hampstead Neighbourhood Plan and is considered unacceptable.
