Environment Agency Flood Data – Thames Estuary

Until recently I was using the following email address to get flood data and maps for the thames estuary:

corporate.services@environment-agency.gov.uk

this email account will soon be closed, the new email to use to contact us will be

ensenquiries@environment-agency.gov.uk

Despite having used the original address for a number of years I received no notice that it would be changed, and have found out the above via lengthy googling.

Hopefully it will save you the time!

In this day an age, would it not have been possible to email past customers to tell them about the change prior to closing the account?

Flood Risk Assessment – Bristol

Flood Risk Assessment – Bristol

SWEL have been commissioned to prepare a flood risk assessment for a mixed use development in Bristol.

The scheme comprises of commercial use of the ground floor, with residential use above. This is a favorable situation, as the ground floor use is less vulnerable as define in the planning practice guidance.


The stated aim of PPG is to ensure that flood risk is taken into account at all stages in the planning process to avoid inappropriate development in areas at risk of flooding, and to direct development away from areas at highest risk. 


This FRA is prepared for the purposes of providing a generalised indication of the potential flood risk to the site, and to identify whether there are any flooding or surface water management issues relating to the development site that may warrant further consideration. 

Bristol is a varied city with regards to flood risk. Some of the hilly areas see very rapid lowering in flood risk moving away from water courses, however area to the west such as Avonmouth experience large areas of low lying ground in Zone 3a which can be problematic from a planning perspective.

There are numerous culvert water courses in Bristol, where rivers has been built over, and now run in tunnels under central areas. 

The flood risk assessment will be prepared on a quick turnaround and supplied to the client in a PDF format.

The use of secondary data will aid in providing this report on a quick turnaround.

The site is an dis-used petrol filling station, there are concrete filled tanks on site, and various buildings with above ground tanks and assicoated storage.

Site Investigation Bristol – Buried Services and Pipework were Present

Site Investigation Bristol – Site Works were completed in One Day

The site works were undertaken in December 2015, with reporting no being progressed.

A full report will be prepared to collate finding of investigation and to compare soil quality against various guide values.

Permit Application Basildon, Essex

Permit Application Basildon, Essex 

Acting on instructions from a company wishing the recycle batteries in Essex. Southwest Environmental are to prepare a permit application for a battery recycling facility. There were many environmental constraints on site, such as a nearby SSSI.

The process involves the splitting of batteries with the segregation of casings, metal plates and electrolytes for onward transfer.

The application was prepared an submitted by SWEL in under 2 weeks, with a great deal of detail being input to the Environmental Risk assessment to describe migratory measures etc.

Example detail:

“All containers are clearly labelled prior to filling. When a particular container or series of containers are full they are transferred off site for further recycling at other licensed facilities, at which point an outgoing transfer documentation is generated and a collection of battery sourced wastes are loaded on to a vehicle for onward transfer.”

Sunlight Daylight Assessment

Southwest Environmental are Environmental Consultants who regularly undertake Sunlight and Daylight Assessments in London, in this case this Assessment took place in Tottenham (N17).

The original plan was for the building to have 5 stories with an extra penthouse single unit on the fitth floor. This was a problematic layout owing to there being very little over shadowing pre-development.

Southwest Environmental were able to inform our client of the maximum possible building height based on the bRE 209 reduction criteria which was around 12 meters in this instance. Th height would change dependent of the scale and distance of the building in relationship to the affected window.

After redcuing the building height to 4 stories the calculations were acceptable, and the rpeort was issued in support of the application.

This report may be used in the appeal process to prove that 4 stories does not create adverse overshadowing conditions.

Fire Prevention Plan – Hereford

Fire Prevention Plan – Hereford 

Recent policy changes have resulted in the need for the majority of waste sites to produce and maintain a fire prevention plan, for their environmental permit.

A fire prevention plan sets out the site specific requirements for the storage of wastes in line with the relevant guidance. There are requirements for stack spacing sand fire rescue service access.

Stack Layouts must be Included

When a fire is extinguished it is often the case that large volume of fire water run off the site and on to surround land, or perhaps in to rivers. The fire prevention plan must set out measures that can be used to prevent this happening.

Stack Sizes must not Exceed Max Limits Imposed

These new requirement for fire prevention plans are applied regardless of past performance, and are being requested more and more often during environmental permit applications of any type.

Down Wind Receptors Must be Considered

The content requirement for a fire prevention plan can be considerable, especially during a bespoke permit application. The fire prevention plans produced by SWEL are for environmental protect matters only and do not deal with health and safety of workers or members of the public.

Energy Statement – Nailsea, North Somerset

Energy Statement – Nailsea, North Somerset

Acting on instructions from a cobstruction company in North Somerset SWEL are to prepare an energy statement for a high specification home to the south of Bristol.

The residential development consists of a large hill side dwelling with terraces and swimming pool. 

The development is to be built to Code for Sustainable Homes Level 3. This would see emissions reductions required and levels of fabric energy efficiency above those specified in the building regulations.

The above axiometric projections were produced by Zebra Architects Worcester.

SWEL have prepared Sustainability and Energy Statements for projects all over the UK. We have experience in Code for Sustainable Homes up to Level 6, and BREEAM Excellent (including refurbishments).

Landscape and Visual Impact Assessment – Rickmansworth

Landscape and Visual Impact Assessment – Rickmansworth

It is fairly standard for LVIAs to be requested when large structures are built in a rural setting, but not so in suburban areas. SWEL were interested to see why a LVIA had been requested for a project within the M25 and sited within a developed area.

The residential project was unusual in its scale and design, however the building’s novel form, and inclusion of features such as roof top gardens will make an attractive replacement in contrast to the existing industrial buildings.

Many Sensitive Visual Receptors in the Area

Sympathetically Designed

SWELspent 12 hours walking and cycling though the surrounding landscape to establish points of visibility, whether these were from foot paths, roads of one of the 2 no. SSSI sites in the surrounding area.

There are a great number of hedge rows in the area which contribute visual screening and these will be included in the ZTVs.

A ZTV (Zone of Theoretical Visibility) using computer modelling to deduce where the project will be visible from. Typically these a “bare earth” ZTVs which ignore vegetation and built screening. A ZTV which includes vegetated and built screening is far more time consuming to produce which is why they are often omitted from LVIAs, but a vital part of any LVIA.
