SEA of North Somerset Council LFRMS Appendix D 1
Assessment Approach
The LFRMS measures have been evaluated in light of their potential significant environmental effects on the
different SEA topics. The assessment of these environmental effects has been informed by professional
judgement and experience with other LFRMS SEAs.
For all measures, the table will be used to evaluate how the environment would be affected, positively or
negatively, from the implementation of the plan in relation to the objectives and indicators that comprise the
environmental baseline. All LFRMS measures will be assessed based on their type and their likely impact
duration and magnitude. Results of the assessment will then be considered in light of the evolution of the
environment in the absence of the plan.
Effects of the LFRMS will be described in terms of whether they are positive, neutral, negative or uncertain, as
shown in Figure D1. Where any cumulative, synergistic or secondary effects are identified they will be noted.
Similarly, if there are any positive or negative synergies between the LFRMS and other plans, programmes or
projects the synergies will also be noted.
Effects of the LFRMS will be described in terms of their:
(a) Nature: whether they are anticipated to be:
• Positive (+);
• Neutral (N);
• Negative (x); or
• Uncertain (?).
(b) Duration: the duration of potential effects are presented in terms of the timescale over which they are
anticipated:
• Short term effects: effects expected in the next 1 to 5 years;
• Medium term effects: effects expected in the next 5 to 10 years; and
• Long term effects: effects expected in the next 10+ years.
(c) Permanence and Reversibility:
• A permanent effect is one which results from a physical change that is anticipated to last beyond the
life of the LFRMS;
• A temporary effect is one which results from an operational change which could change if there is a
change of policy, or a short term condition such as a construction phase related impact;
• A reversible effect is an environmental effect that can be reversed, for example an incident of water
pollution can be cleaned up over time; and
• An irreversible effect is an environmental effect that cannot be reversed such as the loss of a historic
feature or the loss of agricultural soil due to erosion.
(d) Spatial Scale:
• Local: effect is restricted to the immediate location of the proposal or to a specific site or settlement
within North Somerset;
SEA of North Somerset Council LFRMS Appendix D 2
• Regional: effect is anticipated to cover a significant proportion of the counties surrounding North
Somerset; and
• National: effect covers the whole of England and/or the UK (also includes international), or an asset
which is relevant at this scale.
The significance of effects upon each of the SEA objectives will then be evaluated using the scoring criteria
outlined below (Figure D1). The determination of significance would take into account the criteria set out in the
SEA Directive’s Annex II.
++
Major
Positive
The option would be significantly beneficial to the SEA objective by resolving an existing
environmental issue and/or maximising opportunities for environmental enhancement.
+
Minor
Positive
The option would be partially beneficial to the SEA objective by contributing to
resolving an existing environmental issue and/or offering opportunity for some
environmental enhancement. This effect would not be considered to be of significance.
N
Neutral The option would have a neutral effect on the SEA objective.
?
Uncertain
There is insufficient detail available on the option or the baseline situation in order to
assess how significantly the SEA objective would be affected by the option.
x
Minor
Negative
The option would partly undermine the SEA objective by contributing to an
environmental problem and/or partially undermine opportunities for environmental
enhancement. This effect would not be considered to be of significance.
xx
Major
Negative
The option would severely undermine the SEA objective by contributing to an
environmental problem and/or undermining opportunities for environmental
enhancement. This would be considered to be a significant effect.

Compatibility of draft LFRMS ‘Measures’ with SEA objectives
Under each of the LFRMS Objectives in Table 4.2 of the LFRMS, there are a series of measures
that have been put in place to help deliver the LFRMS objectives. These provide more detail
than the LFRMS objectives themselves. The LFRMS measures are described in Chapter 6 of
the main LFRMS report.

Commentary The LFRMS measures were assessed as having a neutral or positive effect for all SEA objectives. Major positive scores were attributed to all
LFRMS measures for the SEA objectives covering climate change adaptation (i.e. through adapting to flood risk) and the protection of material
assets (such as property and infrastructure). There are also likely to be indirect positive effects on human health, water quality and biodiversity as
a result of the implementation of the LFRMS measures. The positive effects on human health are expected as a result of reduced flood risk,
improved public understanding of flood risk and an improved ability of the public to respond to flooding. The positive effects on water quality
are anticipated due to an expected improvement in Flood Risk Management and as a result the reduced risk of the spread of pollutants from
contaminated sites. Further to this, the increased use of natural drainage systems (SUDS) will further help to improve biodiversity, water quality
and soils (through improved filtration of pollutants) and also provide benefits for amenity, human health and landscape character. Positive effects
on biodiversity are predicted due to an increased level of habitat management, particularly along the coast near Weston-super-Mare, and also the
potential creation of additional habitat areas due to the implementation of SUDS policies.
It was not possible to attribute potential positive or negative effects on many SEA objectives as the measures are ‘high level’ at this stage, hence
there are many neutral scores in the matrix. The headline results for each LFRMS Strategic Objective (SO) are shown below;
SO1 LFRMS Measures
The third measure under SO1 provides for the implementation of protocols for the designation of structures or features which have a significant
impact on local flood risk. The designation of key structures and features will help to reduce the risk of these being altered or removed in such a
way as to impact negatively on FRM. In some cases this could help protect structures and features that are also regarded as cultural heritage
assets, hence the positive score attributed under the cultural heritage SEA objective for this measure.

SO2 LFRMS Measures
The second measure under SO2 provides for the development of protocols to control the consenting and enforcement on ordinary watercourses.
These protocols should help to protect the natural hydromorphology of the watercourse, by controlling the volume and type of works undertaken
on land adjacent to the water courses. This measure should help to protect soil resources by protecting Greenfield land, reducing the risk of soil
erosion, maintaining its natural water retention capacity and protecting the vegetation and/or organic debris cover of the soil. It will therefore also
help to protect biodiversity. By protecting watercourses and Greenfield land the amenity value of these resources should also be protected and
opportunities may also arise for it to be enhanced. It is for these reasons that the second measure under SO2 has been given a major positive score
under the hydromorphology SEA objective and a minor positive score under the soils and geology SEA objective.
SO3 LFRMS Measure
All effects on the SEA objectives are expected to be neutral as the measure proposes a continuation of the existing partnership with the SFMB.
SO4 LFRMS Measures
The first measure under SO4 recommends the implementation of policies concerned with the management of the North Somerset coastline near
Weston-super-Mare. If implemented correctly the policy and, as such, the measure, is expected to notably improve biodiversity along the stretch
of coastline, potentially through the protection and enhancement of existing habitats and the creation of new habitat. The management policy is
predicted to help maintain the unique setting and landscape character of North Somerset, therefore also positively impacting upon the cultural
heritage setting and assets of North Somerset indirectly. Measure two is anticipated to have more of a direct impact on the heritage of North
Somerset, hence the major positive score attributed under the cultural heritage SEA objective. The third measure under SO4 provides for the
development of a policy specifically aimed at ensuring that opportunities for the more effective management of surface water in the natural and

built environment are recognised and capitalised on in an effective manner. Examples of this include the retrofitting of green infrastructure to
existing assets, the requirement of new assets to achieve a certain level on a ‘green index’ or the protection and enhancement of existing green
spaces. This measure therefore has been predicted to have a minor positive impact on the SEA objectives of biodiversity, landscape character,
water quality, soils, amenity and human health.
SO5 LFRMS Measures
Measures one and two under SO5 are concerned with the development of protocols and guidance which will facilitate the more widespread
consideration and increased effective use of SUDS in the North Somerset area. The introduction of a SUDS Approval Body and local guidance to
inform planning applications should result in an increase in green space and cover, consequently maintaining and potentially enhancing
biodiversity and amenity. One of the primary benefits arising from the implementation of SUDS is an improvement in the quality of surface water
runoff; due to this a major positive impact was attributed for these measures under the SEA objective of water quality. It is also anticipated, given
that SUDS are highly efficient at controlling the volume and rate of surface runoff, that these measures will result in further, albeit minor, positive
impacts for the SEA objectives of hydromorphology and soils.
SO6 LFRMS Measures
These measures are likely to have neutral effects for all SEA objectives, except for the objective for human health, which is predicted to have a
major positive impact. This is mainly due to an anticipated reduction in the fear of flooding through improved availability of information,
knowledge and preparedness of the general public and also the potential for a reduced risk to people from the direct impacts of flooding.

Cumulative, secondary and synergistic
effects
No cumulative, secondary or synergistic environmental effects have been predicted for flooding or the measures
proposed to reduce flood risk.
Commentary The flood risk measures proposed for Backwell in the short term focus on further investigative study and awareness
raising. This is likely to ultimately result in improved protection of people and properties from flooding, hence there
are major positive impacts predicted for the material assets and human health SEA objectives. For all other SEA
objectives the impacts are expected to be neutral due to the strategic nature of the LFRMS measures at this stage.
Environmental or amenity enhancement
opportunities
In the south of Backwell (Hillside Road) and north (Station Road) urban area there are traditional orchard BAP priority
habitats. To the south-east of the urban area there is some deciduous woodland BAP priority habitat. Backwell is also
close to a Strategic Nature Area of priority woodland habitat with secondary habitats of calcareous grassland and
lowland heath.
The Bucklands Pool/ Backwell Lake Local Nature Reserve is situated between the urban areas of Nailsea and Backwell.
Backwell Lake is also an example of North Somerset BAP ‘open water’ priority habitat. Opportunities to enhance these
sites, particularly the surface water conveyance to Backwell Lake, should be explored with Natural England and Avon
Wildlife Trust.

Cumulative, secondary and synergistic
effects
There is existing cumulative flood risk from surface water, fluvial, highway, sewerage and drainage blocking. Any
management measures are likely to reduce the overall cumulative impacts.
Commentary The flood risk measures proposed for Churchill in the short term focus on further investigative study. This is likely to
ultimately result in improved protection of people and properties from flooding, hence there are major positive
impacts predicted for the material assets and human health SEA objectives. For most other SEA objectives the impacts
are expected to be neutral due to the strategic nature of the LFRMS measures at this stage. Any future measures to
enhance the hydraulic capacity of the watercourse will need to ensure its hydromorphology is protected; hence an
uncertain score is given for the hydromorphology SEA objective for two of the Churchill measures at this strategic
stage.

If it is decided that attenuation basins will be constructed, it may be possible to provide biodiversity or amenity
enhancements, for example through landscaping or planting. Similarly, the construction of new ditches to the south of
Claverham Road and/or new culverts under Claverham Road could also offer small-scale biodiversity enhancement
opportunities.

Consultation with North Somerset Council has shown there are several locations in the district that would benefit from
improved pollution control. This includes Tickenham Causeway, as the ditch which conveys the majority of surface
water from Nailsea to Tickenham, Nailsea and Kenn Moors SSSI (ST 444705) has high levels of phosphates and organic
pollutants; any improvement to the quality of this surface water through LFRMS schemes is likely to lead to
biodiversity benefits for the SSSI, particularly for invertebrate species.
Other SSSIs in the vicinity of Nailsea include West End Meadows (ST 458691), Fields along Youngwood Lane (ST
467695), Batch Farm Meadow (ST 450692) and Nursebatch Farm Fields (ST 453691).
Nailsea is close to the Strategic Nature Area of Nailsea Moor, a priority habitat of Coastal and Floodplain Grazing

Cumulative, secondary and synergistic
effects
There is existing cumulative flood risk from surface water and fluvial sources. Any management measures are likely to
reduce the overall cumulative impacts.
Commentary The flood risk measures proposed for Pill in the short term focus on further investigative study and survey. This is
likely to ultimately result in improved protection of people and properties from flooding, hence there are major
positive impacts predicted for the material assets and human health SEA objectives. For all other SEA objectives the
impacts are expected to be neutral due to the strategic nature of the LFRMS measures at this stage.
Environmental or amenity enhancement
opportunities
Priory Farm and Pill Paddock Local Nature Reserves are both close to Pill. NSC has recognised that Pill currently has
an insufficient supply of woodland, formal park and public garden and conservation sites. Any opportunities to
improve this provision should be explored.
Pill lies within a strategic area of coastal habitat shown on the Strategic Nature Area map of the south west.
Opportunities to enhance the biodiversity, wildlife corridors, amenity or access to the Local Nature Reserves or other
habitats should be explored.

Cumulative, secondary and synergistic
effects
There is existing cumulative flood risk from surface water and highway drainage sources. Any management measures
are likely to reduce the overall cumulative impacts.
Commentary The flood risk measure proposed for Portbury in the short term includes different options to intercept and divert
pluvial runoff. This is likely to ultimately result in improved protection of people and properties from flooding, hence
there are major positive impacts predicted for the material assets and human health SEA objectives. For all other SEA
objectives the impacts are expected to be neutral due to the strategic nature of the LFRMS measures at this stage.
Environmental or amenity enhancement
opportunities
Portbury Wharf, Prior’s Wood and Priory Farm Local Nature Reserves are all close to Portbury. There are also various
SSSIs locally, listed in the Environmental Report.
Portbury is within a Strategic Nature Area, with primary woodland habitat and secondary habitats of calcareous and
neutral grassland.
Opportunities to enhance the biodiversity, wildlife corridors, amenity or access to the Local Nature Reserves or SSSIs
should be explored.

The Weston Woods Local Nature Reserve lies to the north of the urban area. Ellenborough Park West SSSI is close to
the seafront in central Weston and Uphill Cliff SSSI/ LNR, Purn Hill and Bleadon Hill SSSIs all lie to the south of the
urban area. The SWMP will be able to identify if there are likely to be any flood risk measures required in the vicinity
of these schemes and, if so, whether any mitigation or enhancement is required. Weston is also within the project area
of the North Somerset Wetland Programme so there may be opportunities to improve wetland habitats in the Weston
area.

Cumulative, secondary and synergistic

No cumulative, secondary or synergistic environmental effects have been predicted for flooding or the measures
proposed to reduce flood risk.
Commentary The flood risk measures proposed for Winscombe in the short term focus on further investigative study. This is likely
to ultimately result in improved protection of people and properties from flooding, hence there are major positive
impacts predicted for the material assets and human health SEA objectives. For most other SEA objectives the impacts
are expected to be neutral due to the strategic nature of the LFRMS measures at this stage. Any future measures to
enhance the hydraulic capacity of culverts will need to ensure the natural hydromorphology of this watercourse is
protected; hence an uncertain score is given for the hydromorphology SEA objective at this strategic stage.
Environmental or amenity enhancement
opportunities
Cheddar Valley Railway Walk is a linear Local Nature Reserve lying to the west of Winscombe. The Mendip Hills
AONB and some deciduous woodland BAP priority habitat also lie to the west of the urban area. The LNR is in close
proximity to ‘The Lynch and The Green’, areas where there are known highway drainage issues. NSC has recognised
that Winscombe currently has an insufficient supply of neighbourhood open space. Opportunities to enhance the LNR,
BAP priority habitat or neighbourhood open space should be explored with Natural England and Avon Wildlife Trust.

There are traditional orchard and deciduous woodland BAP priority habitats in the ‘Alburys’/High Street area in the
north of Wrington. There are also larger areas of both these BAP habitats to the north of the urban area.
Wrington contains examples of ‘ancient and/or species-rich hedgerows’, which are listed in the North Somerset BAP as
being good examples of ‘boundary and linear features’ priority habitat.

If it is decided that upstream storage options will be constructed, it may be possible to provide biodiversity or amenity
enhancements, for example through landscaping or planting.
