ARGYLL AND BUTE COUNCIL ENVIRONMENT, DEVELOPMENT AND
INFRASTRUCTURE COMMITTEE
ROADS AND INFRASTRUCTURE 12 SEPTEMBER 2024
CAMPBELTOWN FLOOD PROTECTION SCHEME  
1.0 INTRODUCTION 
1.1 
1.2
Campbeltown has suffered from flooding over several decades.
Consultation exercises, flood study and design work and to mitigate flooding
in the majority of situations was carried out for a number of years and
resulted in Campbeltown Flood Protection Scheme. 
This report forms the closure report for Campbeltown Flood Protection
Scheme (CFPS) and provides an update on some of the key elements of
the project which is substantially complete.   
2.0 RECOMMENDATIONS 
2.1 The Environment, Development and Infrastructure Committee is asked to
consider the report. 
3.0 DETAIL 
Background 
3.1 The Environment, Development and Infrastructure (EDI) Committee on 5
December 2019 confirmed the Campbeltown Flood Protection Scheme with
modification and recommended to Council to approve additional budget to
take the project to tender readiness.   
3.2 On 28 January 2020 the Council submitted, in accordance with Regulation
14 (2) of the Flood Risk Management (Flood Protection Schemes,
Potentially Vulnerable Areas and Local Plan Districts (Scotland))
Regulations 2010, a request for Scottish Ministers to direct that deemed
planning permission be granted to CFPS.  In line with Section 65 of the
Flood Risk Management (Scotland) Act 2009, Scottish Ministers directed,
under Section 57 of the Town and Country Planning (Scotland) Act 1998,
that planning permission for the development is deemed to be granted,
subject to conditions. 
3.3 CFPS is the first scheme being promoted in Argyll and Bute under the Flood
Risk Management (Scotland) Act 2009.

CFPS comprises of Millknowe Flood Storage Reservoir – an area in
previously existing farmland south of the Snipefield Industrial Estate which
will temporarily store water in extreme flood events.  The flood storage area
is formed by a combination of flood walls and bunds.  In combination with
this flood storage area, the existing culvert from the reservoir to the
Balgreggan intake was upsized to improve flow capacity.  The scheme also
includes a surface water management scheme in the Burnside and
Meadows areas to reduce pressure on existing combined network.   
Prior to works commencing and throughout, extensive engagement has
taken place with the local community including a number of pop up/drop in
events where the delivery team were available to provide information and
answer queries directly. This approach was well received.

The construction contract with Dawson WAM was certified complete on 10
May 2024. All works under the Dawson WAM construction contract have
been completed except for minor maintenance items and items included on
the defects list.  The Defects Date is 10 May 2026, at which the 2.5%
Retention payment of (£338,386) will be paid to the Contractor and the
NEC3 Engineering and Construction Contract will be concluded. 
A Leader Drain discovered on Highlands and Islands Enterprise land,
historic land drain, previously unidentified, had to be diverted into the
Millknowe Burn as it was not possible to maintain previous alignment though
new flood wall.  Investigations complete, report prepared and meetings with
landowners carried out to establish and conclude the engineering matters
around this enquiry. It is understood that the leader drain had been
severed/partially severed downstream in the 1980s. 
Property Flood Resilience measures still to be commenced under a
separate contract.  Procurement for this contract is anticipated to take place
during autumn 2024. Land acquisition and compensation costs still to be
concluded although these elements have budget provision in place. 
The table below provides a summary of financial information relating to the
project: 
Budget £15.925m (all project costs,
including construction,
professional services, land costs,

Affordability 
3.11 As at August 2024, the scheme is estimated to cost £15.925m. At the time
of contract award of the main construction works, the scheme’s estimated
cost of £15.215m secured Scottish Government funding of 80% of project
value (£12.172m) with Argyll and Bute Council contributing 20% (£3.043m). 
An additional £710k has been secured for additional works requested by the
Council for the betterment of Burnside Square and for additional costs
incurred through the contract. 
3.12 
3.13 
4. Works which were not funded by original scheme budget are detailed below: 
Main Construction Contract 
The committed construction value of £13.535m is in excess of the original
contract value of £12.693m by a value of £0.842m. This is made up of a
number of compensation events which have been managed through the
Contract and, in addition to the FPS, further enhancement to Burnside
Square as detailed below.
Additional funding has been secured and is in place.  The remaining,
smaller elements of the Scheme all currently have adequate funding in

place. This is normal for a construction contract, with all additional costs
being managed by both the internal Council team in Infrastructure Design
and by external consultants, AECOM – both in conjunction with the
contractor, Dawson WAM and all in accordance with the Conditions of
Contract. 
Burnside Square (Additional works beyond flood protection scheme
contract works) 
There are general improvement works to the square that have been
constructed as part of the scheme, under ongoing consultation during the
period since construction began, rather than from a prepared masterplan.
A value of approximately £0.230m, not funded by the original funding level
of the FPS, is included within the overall FPS construction contract. 
Funding is in place for these additional works. 
4.0  CONCLUSION 
4.1 CFPS has successfully delivered a sustainable project to protect
Campbeltown, its residents and businesses from flood risk.  The Property
Flood Resilience works shall be progressed in due course along with the
remainder of small, ongoing final works on the main contract. 
5.0  IMPLICATIONS 
5.1 Policy – Works are in accordance with the Local Flood Risk Management
Plan 2016-2022 as endorsed by Council. Local Authorities have powers
under Flood Risk Management (Scotland) Act 2009 “to manage flood risk
and to take forward a flood protection scheme.” The Campbeltown Flood
Protection Scheme enabled Argyll and Bute Council to enact this power
under the Flood Risk Management Policy. 
5.2 Financial – The Scottish Government funded 80% of the project cost at the
time of contract award of the main construction contract with 20% plus
values over the project cost at that time required from the Council.  The
Council’s 20% share and additional funding was included within capital
plans.  £1.78m is allocated to 2024/25, £10k is allocated to 2025/26 and
£387k is allocated to 2026/27. 
5.3 Legal – Please see section 4.26 – 4.28. 
5.4 HR – None 
5.5 Fairer Scotland Duty: 
5.5.1 Equalities – None 
5.5.2 Socio-Economic Duty – The key areas in Campbeltown which were at risk
of flooding (Millknowe Road, Saddell Street, Longrow etc.) are in areas of

Page 6

average and relatively high social vulnerability. This, paired with the risk of
flooding, results in relatively high and acute flood disadvantage respectively.
Wider benefits were therefore an important consideration of the scheme.
The scheme achieved multiple benefits which have not been explicitly
costed but added significant value to the scheme from a socio-economic
and environmental perspective. These were considered qualitatively as part
of the options appraisal process to select a fully sustainable scheme. The
wider benefits associated works are as follows:
• Reduction of flooding reduces social disadvantage
• Improved local resident’s health and wellbeing by reducing stress
associated with flooding
• Reduced risk of flooding at the police and fire stations.
• Reduced flooding within the Campbeltown Conservation Area which is
home to a number of Listed Buildings maintain cultural heritage of the
area for future. 
• Reduced risk to community assets including Tesco Metro, Kinloch Bar,
Kinloch Park, Kinloch Park football pitches
• Reduced risk to key roads within Campbeltown improving accessibility
for residents and emergency services during storms
• Greater community engagement in understanding flood risk 
• Reduced load on the sewer network therefore reduced risk of manhole
flooding and associated health impacts
• Reduced load on sewer network therefore reduced risk of pollution to
waterbodies associated with the combined sewer network 
• Reduce load on the combined sewer network and associated health
risk from this flooding
• Reduced risk of damage to sewer assets through overloading 
• Improved landscape character in the Meadows through addition of
detention basins and landscape scheme
• Improved water quality in the Witch Burn associated with treatment of
surface water at filter drains and detention basins in the Meadows
• Improved water quality in Campbeltown Loch through reduced
likelihood of Combined Sewer Overflow spills 
• Improved habitat for wildlife through construction of detention basins 
5.5.3 Islands Duty – none known 
5.6 Climate Change – We will endeavour to minimise carbon footprint of this
project. Please see section 4.23 to 4.29 
5.7 Risk – CFPS will reduce the risk of flooding 
5.8 Customer Service – none known 
5.9 The Rights of the Child (UNCRC) – none known
