WFD Cycle 2 Lake Phytobenthos Classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for phytobenthos in lakes. Phytobenthos or diatoms can be used to indicate the ecological status of a lake.  A biological index called the Trophic Diatom Index (TDI) is calculated using information about the environmental preferences of the individual diatom taxa present in the sample.  The actual (observed) TDI scores are compared with a predicted TDI score (reflecting a lake in pristine condition).  The comparison of the observed to expected scores is known as an Ecological Quality Ratio (EQR).  EQRs are used to produce a phytobenthos classification (High, Good, Moderate, Poor, Bad) of the water body for Water Framework Directive (WFD) purposes.

WFD Cycle 2 Lake Ammonia Classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Ammonia in lakes. Ammonia is a decay product of nitrogenous organic wastes and of the breakdown of animal and vegetable wastes. Sewage effluent is a major source, as are agricultural diffuse sources associated with fertiliser application. Ammonia is used in many cleaning products and in fermentation processes.

 Ammonia data is run through a database that calculates summary statistics (Mean, standard deviation) at each site based on the number of samples taken in the classification period. These statistics are then entered into a calculator tool to generate classifications. Ammonia standards are used for Ammonia classification and they set up the boundaries between the various status levels e.g. High, Good, Moderate etc. The standards are ‘Waterbody’ specific based on the Typology of the lake, the altitude and alkalinity.

WFD Cycle 2 Lake ANC Classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Acid Neutralizing Capacity (ANC) in lakes. Acid Neutralising Capacity (ANC) is one of the physicochemical quality elements along with Ammonia, pH, Total phosphorus and Dissolved Oxygen that make up the Physicochemical (Phy-chem) quality status of lakes water bodies.  The Phys-chem status and the ecological status are used together to determine the overall status of a water body

ANC is calculated using Alkalinity and Dissolved Oxygen and uses the pH value to apply the correct multiplication factor. No typology data or information is required and classification of status is purely based on the available chemical data. ANC classifications are High, Good or Moderate.

WFD Cycle 2 DO Rivers Classification

This dataset is a subset of the "WFD Classification Status Cycle 2" product. It contains summary data for the element dissolved oxygen (DO) for river water bodies, as used in the classification for Ecological status for the water framework directive (WFD). The DO classification dataset is an element of the physico-chemical group or element set and is used to consider particular phyisco-chemical conditions. Oxygen in rivers is affected by complex interactions between ecological processes, and by anthropogenic pressures. Site classifications are derived from spot sampling monitoring data. The results of which are calculated into percentiles and assessed against two sets of environmental quality standards (EQS), which are derived from site typology. Site classifications for DO use categories of High, Good, Moderate, Poor, and Bad. Attribution statement: © Environment Agency copyright and/or database right 2016. All rights reserved.

Event Duration Monitoring - Storm Overflows - Bathing Season Returns

This Event Duration Monitoring (EDM) dataset relates to the performance of storm overflows in England. Water and Sewerage Companies (WaSC) submit this data to the Environment Agency each year as part of the Bathing Season Return, in order to fulfil their permitted conditions to discharge from these storm overflows under the Environmental Permitting Regulations.

Data files are provided by year and, where applicable, include a separate sheet for each WaSC with storm overflows in England. Each WaSC sheet shows how often and for how long each monitored storm overflow discharged during the EDM Bathing Season (1 May – 30 September). The dataset also explains why EDM may have provided information for less than 90% of the relevant return period, and why an overflow may have high spill counts during that time. These datasets reflect the best information available to the WaSC at the time of submission.

The datasets from 2023 onwards also include key summary data tables. These summary tables provide information such as the number of storm overflows with EDM, the number returning spill counts, and the average spill duration and average spill count for each WaSC.

A dataset README guide is also provided from the 2025 dataset onwards, offering further information to help users understand and interpret the data. Attribution statement: © Environment Agency copyright and/or database right 2025. All rights reserved.

Wiltshire Council - Conservation Areas

The local planning authority have a statutory duty to designate and manage conservation areas under the Planning (Listed Buildings and Conservation Areas) Act 1990 (legislation.gov.uk)(opens new window).
Conservation areas are defined as an area of special architectural or historic interest where the original appearance is preserved or enhanced. Most of Wiltshire's conservation areas are made up of historic parts of towns and villages with some others including special landscapes such as the canal corridor at Wilcot.
Most conservation areas have a high concentration of historic buildings, many of which are listed. The character of a conservation area is not defined by these buildings alone. The setting, location, features and open spaces also have a large part to play. Good partnership working between relevant authorities is required to protect the local character and positively reinforce change.

Pavement Widths

A line dataset representing estimated pavement (footway) width across the City of London. Each line contains a numeric value indicating the width of the pavement at that location. Width values are derived from pavement polygon geometries or road‑edge‑to‑building‑line measurements and are assigned to a uniform grid for spatial analysis. The dataset is based on Ordnance Survey base mapping, which may not reflect recent highway or public realm changes, temporary works, newly installed infrastructure, or schemes implemented after the date of the OS data extract. As a result, pavement widths may be outdated in areas where changes have occurred.

Area of Special Archaeological Potential

The town of Nantwich in Cheshire contains archaeological deposits of national importance. Much of this material is preserved beneath or within a deep, sometimes organic, waterlogged deposit which, in places, is more than three metres deep. The quality of these waterlogged remains is exceptional and is comparable to the archaeological deposits at Carlisle, York and London. The Area of Special Archaeological Potential identifies the zones within the town where well-preserved, waterlogged archaeological deposits are known to survive.

Historic Landscape Characterisation

The Cheshire Historic Landscape Characterisation project recorded the visible evidence of human history, which forms the modern landscape. This has been achieved by identifying landscape attributes from a range of historical maps. These attributes are categorised into a series of Groups, Types and Sub-types and their extent mapped and analysed using a Geographic Information System. This work enabled the historic character of any given area to be presented cartographically together with the historic processes which formed it.

Copies of the project reports are available via the Cheshire Archaeology web site: http://www.cheshirearchaeology.org.uk/?page_id=175.

2015 SSE Renewables Beatrice Offshore Wind Farm pre-construction benthic grab survey

A pre-construction benthic characterisation survey was conducted by APEM Ltd at the proposed Beatrice Offshore Wind Farm (OWF) and Annex 1 Habitat Survey of the Offshore Transmission Works (OfTW) cable corridor (APEM ref 413984, client ref ED518) between the 22nd and the 27th June 2015. 
           The aim of the survey was to collect grab samples that will provide baseline data on the benthic ecology and sediment composition within the OWF area. Additionally the survey was to utilise Drop Down Video (DDV) to determine the presence of potential cobble reef Annex 1 habitats (EC Habitats Directive) the OfTW cable export corridor and investigate sites of potential archaeological importance within both the OWF area and export route.
           Twelve grab stations were selected to provide representative coverage of the SS.SCS.ICS.MoeVen (Moerella spp. with venerid bivalves in infralittoral gravelly sand) biotope that was identified as being of high importance in the Beatrice OWF Environmental Statement and Supplemental Environmental Impact Statement and is representative of the Tide-swept coarse sands with burrowing bivalves Priority Marine Feature. Ten of the stations were located within the OWF boundary, with two reference stations located to the north east of the OWF. All stations corresponded to locations that were sampled during the EIA baseline characterisation study undertaken in 2010 (CMACS, 2011). At each of the twelve locations three replicate samples were acquired using a 0.1m2 Hamon grab. Each replicate was then sub-sampled for both macrofauna and Particle Size Analysis (PSA).
