BASELINE DATA Flashcards
Structure of Envt Statement
Part II Schedule 4
- description of development; information on the site, design and size of the development.
- description of measures to avoid, reduce and possibly remedy significant adverse effects.
- data required to identify and assess the main effects which the development is likely to have on the environment.
Proposal- detail
Rochdale Envelope
- outline of main alternatives studied by the applicant or appellant and an indication of the main reasons for the choice made, taking into account the environmental effects.
- A non-technical summary of the information provided under paragraphs 1 to 4 of this Part.
Rochdale Envelope
Detail must be such to enable proper assessment of likely impacts and necessary mitigation
Consider range of possibilities.

Consultation process
Who did you talk to? iterative process Planning Act 2008- duty of developer to engage meaningful with: Affected communities local authority other statutory consulates pre application stage
What must the developer do?
produce and publicise a statement of community consultation. must consult with/ have regard to the views of any relevant local authority.

Typical contents of each section
intro to area importance and designation scoping findings methodologies baseline data impact prediction suggested mitigation glossary and abbreviation non tech summary
Digital revolution
1980s- EIS poorly put together mixed documentation
1990s- Early 2000s- professionally produced often single volume. Available free or at nominal charge
2006 onwards: all documents online via LPA planning websites; paper copies only by request at large cost (£200)
new directive (2014): requires all documentation to be available online across the EU
baseline data
significant parrots (human beings, flora, fauna, soil, water, air, climate, material assets, cultural heritage) collect existing (desk/consult) gathering exsisting by survey
Aims of collecting baseline data
asses value of baseline envy (regional/ national impact)
provide data to predict changes which development might cause
provide baseline for future monitoring
Model for gathering Data
draw up limits to area:
of development
potential impacts
Desk study
fieldwork: phase 1 and phase 2&3
Limits of Envt impacts
the site
immediate locality
wider effects (national, international, global)
(construction operation and decommissioning phases should be assessed.)
HEATHROW EXTENTION. impacts
Site:
land intake-conservation, hydrology
locally- road improvements employment, noise (local and on flight paths)
nationally- status of impacted conservation area, economy: local and national effects
internationally: greenhouse emissions, trade benefits, tourism impacts
HEATHROW COSTS
planning process- £63 mill over 14 years
46 month public enquiry
construction costs=£4.2 billion
Need for HEATHROW extension
if not built cost UK £600 mil year in exports
larger aeroplanes need bigger infra
accommodating modern planes can reduce air and noise poll whilst increasing passenger numbers
Impacts of Construction phase HEATHROW
6 years (2002-2006) = phase 1 further phase completed in 2011
workforce (60 contractors) noise traffic dust security land take hydrology wider infrastructure (road, rail links, car parks) radar dust use of resources cultural heritage
Impacts of operation phase HEATHROW
traffic noise (traffic and planes) air pollution run off economy: jobs services global impacts (climate change, trade)
CHANNEL TUNNLE
site itself: major land intake
Locally: difficulty finding an acceptable route (though Kent and London)
National: short term- increase in road traffic. long term- potential short to freight on rail
international: improved trade within EU. National security/ health risk.
IKEA SOUTHAMPTON
land take of limited importance (brownfield site in urban area)
4 storey building, 600 seat restaurant, 891 space car park opposite leisure world
IKEA SOUTHAMPTON
immediate area:
construction: noise dust, odours, traffic, infrastructure, landscape and heritage
operation: traffic (15% increase predicted- junction improvements proposed as mitigation) Council requiring bus links to station, city centre, ferries.
Landscape heritage
potentially economic impacts on other local businesses (John Lewis)
beyond immediate:
traffic, in operation as far as regional motorways and interactions with docks operations and events
economic:
£55 m pa turnover, 500 jobs locally) business across the region may be impacted
Desk Study: statutory consultees
obliged to provide information already in their possesion during an EIA.
Examples of statutory consultees
Natural England Environment Agency Local authorities highway agency marine management organisation RSPB national trust local chamber of commerce business groups cyclists windsurfer
How much detail?
decision based on scoping and initial findings
general (phase 1) require i.e. economy habitat mapping
anything of interest? phase 2- species lists or
phase 3 counts of individual organisms
clean reference sites for term monitoring may be needed.
Estabilishing significance
Glasson- 150 difference methods predicting environmental impacts
definition (dibden ES): one where the predicted net impact of the activity will (regardless of its size) exceed the normal variation in baseline conditions, as they are predicted to be if the proposals do not go ahead.
measuring a variation from the usual and normal environment- does not by itself indicate the importance of an impact.
