Traffic Impact Assessment – Essex

Traffic Impact Assessment – Grays, Essex

A waste recycling firm are applying for planning permission for a change of use. The change of use triggers the requrement for a traffic impact assessment.

First off the baseline conditions must be considered which involves a through traffic count on the surrounding road network.

Traffic Impact – Lots of Data

This data is then used to calculate likely percentage increases from the development.

The Traffic Impact assessment includes commentary on the modal split of traffic in the area and the trip generation associated with the proposed development.

Traffic Impact Assessment – Most counts are now automated.

When considering the different modes of transport it is important to consider that  a small number of HGVs are likely to represent a higher percentage increase, as opposed to a small number of cars the affect of which is diluted within the often high numbers of trips that are generated by cars on most roads on a day to day basis.

Odour Impact Assessment & Odour Management Plan – Tiverton

Odour Impact Assessment  & Odour Management Plan – Tiverton

SWEL were engaged to provide supporting planning documents for a broiler breeder chicken shed near Tiverton, Devon. An odour impact assessment uses an atmospheric model to gauge the diffusion of an odour plume, plotting modelled odour concentrations on a grid, this grid is then used to create contours.

An odour impact assessment was required to assess odour impacts from the proposed shed which was to house 36,000 chickens. This may seem a large number but by today’s standards this s a relatively small shed, sheds of 300,000 chickens are not uncommon.

Typically it is necessary to statistically manipulate results and give a US 95 or US 99 value for odour concentration derived balancing of model out puts and wind direction etc. but in this instance it was not necessary, worst case scenarios were modelled and found to be within accepted limits.

An odour management plan was also produced,  this is an operational document and is to be used by the site operator during the operational phase of the broiler breeder sheds. Odour control in large scale chicken sheds involves controlling  diet, watering and ventilation rates amongst other things.

Flood Risk Assessment – Exmouth

If you find out that your site is in Flood Zone 3a this does not mean that you will not be able to build on / develop the site. There will be more paper work, and you may have to wait some time for the Environment agency to decide whether your site is in fact suitable, but in 90% of cases Zone 3a will not pose as an insurmountable barrier.

Such was the case with a site in Exmouth, near Exeter, Devon where an infill building plot, was partially within flood zone 3a. It was quickly established that a variance in ground elevation was the cause of this  incursion, and that likely ground raising associated with the proposed develop would effectively place the proposed dwelling above flood water levels.

Sunlight & Daylight Assessment – Hackney

SWEl have just sucessfull completed a sunlight & daylight assessment for an unusual retrofit project in Cazenove (Hackney) London.

The project invloves the install of a further two stories on top of an existing building the design is modern and well considered to reduce daylighting impacts, with a tiered design with width decreasing upwards.

The surrounding buildings were subject to considerable overshadowing prior to the development, and as such only minimal reductions in enjoyed light were acceptable.

Sunlight & Daylight reduction post project were within limits set in the relavent guidance, and as such the project with minor alterations was recommended to proceed.

Ship Recycling Project Management Cornwall UK – Intro

After 100 years or more of service a typical motor fishing vessel is coated in hazardous chemicals and has many types of oil driven systems, engines and fuels stored within it. To dismantle a motor fishing vessel in situ requires a project management strategy that puts protection of the environment at the forefront.

Ship Recycling Project Management Cornwall UK – The Ship

Wooden fishing vessels have a low scrap value, and as such are prone to being left to rot in harbours and estuaries across the UK.
A Fine Boat in her Day – Now a Liability

Ship Recycling Project Management Cornwall UK – The Method

Obviously to explain the method in detail here would be rather long winded. But care was taken through out that the marine environment should be protected at all stages. As with all waste management activities the key is to segregate the maximum percentage of arising wastes so as to retrieve recyclable scrap, and minimize wastes to landfill.
Arising wastes consisted mostly of wood, concrete, iron and steel.

Ship Recycling Project Management Cornwall UK – The Result

With the ship now removed from the harbour all stakeholders are happy. The harbour is at a lower risk from pollution incidents relating to the derelict boats, there is more room, and a maximum percentage of waste was diverted from land fill.

Sequential Test for Planning Application – Catterick, North Yorkshire

It can be the case that planning authorities will take exception to a particular project and make requests for all kinds of extra information, to support the application, at a level of detial that would not normally be required.

Southwest Environmental were approached by a developer who was building a number of residential units in a Flood Zone 3. An initial flood risk assessment had been undertaken previously by a consultant and appeared to be of sufficient detail, however the local planning authority required extra clarification with regards to the sequential test.

SWEL have an well proven method for carrying out sequential test, and this was applied once more in this instance.

The project was well considered with regards to flood risk, the buildings design and choice of materials were  well chosen.

Air Quality Assessment – Brent, London (NW6)

Acting on instructions from a client in Brent, London Southwest Environmental are to undertake a detailed indoor air quality assessment.

A resident approached Southwest Environmental Limited with concerns over the quality of air within their living space. It was thought that air quality might be lowered owing to the neighbouring property uses.

A passive monitoring scheme is being undertaken over a 30 days period so as to establish indoor air quality. A very wide spectrum of common air borne determinants are to be tested for including a range of VOCs (volatile organic compounds) and nicotine.

Monitored levels will then be compared with known safe levels as published by the WHO, and HSE.

If you have any requirements for indoor air quality monitoring and subsequent interpretive anlaysis then pleas egt in touch we would be happy to discuss your needs.

Desktop Study – Dunsford, Exeter

A farmer was looking to satisfy various pre-commencement planning conditions listed on his planning approval for an agricultural dwelling in Dunsford near Exeter.

SWEL were not sure why a desktop study was requested as the site was green field . . . although it was adjacent to some existing farm buildings. Discussions with Dartmoor National Park Authority had not resulted in the condition being removed and as such the desktop study was carried out, with the obvious recommendation that conditions relating to contaminated land were discharged.

Southwest Environmental have just completed a Flood risk Assessment for a small project in Wandsworth London.  The development saw the retention of a typical terraced house with an extension to the rear.

The property had a basement to include living accommodation but not sleeping accommodation. This is an important differentiation.

The sequential test was not required for this development as it is a domestic extension.

In support of the application Southwest Environmental will prepare:

  • Application Forms
  • Environmental Management System
  • Site Condition Report
  • Waste Policy
  • Risk Assessment

The site operator is already preparing to undertake relevant training such as EPOC.
