Carlisle City Council Area
•Close to Scottish Border and Gretna Green to north
•A small city, population 105,200 in 2008
• about 30% of Carlisle District‘s population is rural, many in sparsely populated areas
•Solway and Pennines AONB
•Northumberland and Lake District NP,
• Eden Valley, Rivers Eden, Caldew and Petteril rivers
Urban Carlisle
The focus of the study
About 70% of Carlisle District ‘s population is in this urban area
City of Carlisle today(Growing Carlisle: An Economic Strategy for the Carlisle City
Region, Carlisle Renaissance , January 2008)
• Freestanding small city : nearest major conurbations Newcastle 60 miles to the East, Glasgow to the North
• County town of Cumbria, administrative centre • Historic cathedral city, Hadrian’s Wall nearby, 2000 years of history• University city with creation of University of Cumbria in 2007• Diverse and stable local economy: food production, retail, transport and
services, tourism• High employment levels but low wages and GVA c.f. NW and England• Low levels of educational attainment c.f. NW and England• 6 wards in urban Carlisle within 20% most deprived in England according
to the Index of Multiple Deprivation
Conceptualising and modelling socio-economic change
Socio-economic modelling techniques used in Carlisle
• ONS demographic modelling• POPGROUP, a population forecasting tool supplied by Manchester
University for forecasts to 2031 for Carlisle population/housing scenarios • Experian economic forecasting model linked to POPGROUP used for
Carlisle economic scenarios to 2016 (for both see: Cumbria Housing Strategy 2006-2011, Carlisle City Council 2009)
• Cambridge Econometrics’ Local Economy Forecasting Model (LEFM) for projections of Carlisle economy to 2020(see Carlisle Renaissance Economic Strategy SWOT analysis, SQW Ltd. 2006)
Issues• Based on past trends and depend on accurate baseline data • Do not reflect downturn in UK/world economy 2008 -2010 onwards• Linking models added uncertainty
Growing Carlisle: a policy consensus and aspiration
2005 floods: a catalyst for making Carlisle a better place by growing Carlisle’s population and economyEndorsed by documents and analyses:• Carlisle Renaissance: Economic Strategy SWOT Analysis (SQW Ltd

Growing Carlisle: Opportunities (Cumbria Economic Strategy 2009-19, 2009)
• Population growth: Growth point status confirmed by Government
• Prioritisation for growth within the Regional Economic Strategy – public and private sector investment
• Establishment of the University of Cumbria HQ in Carlisle• Development of Carlisle Airport• Development of key economic sectors e.g. tourism, retail,
food, logistics, financial and business, education and health• Scope for allocation of additional land for housing and
employment: land is available

Implications of socio-economic futures for flood risk
These will depend on:
• How much and what future residential and employment development (scenarios considered above)
• Planning policies, availability and allocation of development land also on private sector decisions
• Where: geographic location of development in relation to flood risk
Development and flood risk
• Most of the urban area at risk/flooded in 2005 will have flood
defences to the 1 in 200 standard.
• Carlisle District Local Development Plan (2008) robust policies for floodplains (developed or undeveloped) and coastal land reflecting PPS 25 (LE 27 and LE 28)
• Extreme flood events
Planning policies and land allocations
Three possible options for future land allocations.
• Brownfield sites mainly City Centre. RSS required 50% of housing development on this land.
Rickergate and Caldew Riverside flood plain sites identifies for redevelopment.
• Areas on the fringe of built up City. No greenbelt in Carlisle. Mostly not in 1 in 100 floodplain.e.g. planned development of 800 houses and other facilities at Morton, not floodplain
• Developments in /outside City urban area adjacent to M6 Junctions J42, J43 and J44 (near Kingmoor Business Park.) Some land near J42 and J43 (Rosehill) at flood risk
EA - development of Carlisle possible without using flood risk land

Carlisle urban futures scenarios
Three scenarios:
• Low growth scenario
• Moderate growth /business as usual scenario
• High aspirational growth scenario
Summary Low Growth Scenario: No increase and possible decline in property /people at risk in 1 in 100 FRA URBAN AREA
• Population: static or decline - No net migration, 71,000 in 2006 in urban area• Economy/employment: Low growth, stagnant or shrinking • Housing Extra dwellings: in 203 , in 2051: most outside FRAs• Health, public administration: No building on Rickergate site• Education: No Cumbria University HQ etc on Caldew Riverside • Leisure: Sands Centre 25% increase in size, No new theatre.• Tourism: No 4 star hotel and conference facilities on Rickergate site• Food manufacturing: increased investment , decline in employment. Of major
firms, only McVities at risk, might relocate.• Other manufacturing: decline, possible loss of major firm e.g. Pirelli through
restructuring/relocation but major firms are not in the 1 in 100 FRA• Transport, distribution: limited airport expansion and distribution, not in FRA• CNDR developed by 2031 but EA approved . No Southern Relief Road.• No expansion of business and professional, digital and creative industries.
Summary: moderate growth/business as usual scenario: modest increase in property /people at risk in 1 in 100 FRA: URBAN AREA
• Population: modest net migration and growth in population to 75,000 in 2051• Housing (current rate): Extra dwellings: 5,000 by 2031 , 10,000 in 2051: 5% FRAs?• Employment (baseline): modest increase in FTEs, I,700 by 3031; 2,700 by 2051• Retail: limited development of part of Rickergate site for retail• Health, public administration: small redevelopment on Rickergate site• Education: Cumbria University HQ on part of Caldew Riverside site• Leisure: Sands Centre 50% increase in size, No new theatre.• Tourism: No 4 star hotel and conference facilities on Rickergate site• Food manufacturing: increased investment , stable employment. No loss of major
firms.• Other manufacturing: No or low growth, no loss of major firm e.g. Pirelli ; major firms
are not in the 1 in 100 FRA• Transport,/distribution: Further airport expansion and distribution• CNDR developed by 2031 but EA approved . No Southern Relief Road.• Small expansion of business and professional, digital and creative industries.
Summary: aspirational/growth point bid scenario: some increase in property /people at risk in 1 in 100 FRA: URBAN AREA
• Population: substantial net migration, growth in population to 81,000 in 2031, to 92,000 in 2051
• Housing (Growth Bid rate): Extra dwellings: 10,000 by 2031, 18,000 in 2051: 5% FRAs?
• Employment (baseline): modest increase in FTEs, I,700 by 3031; 2,700 by 2051• Retail: substantial development of part of Rickergate site for retail• Health, public administration: Full redevelopment of Rickergate site• Education: Cumbria University on all of Caldew Riverside site and adjacent sites• Leisure: Sands Centre 100% increase in size, new theatre.• Tourism: A 4 star hotel and conference facilities on Rickergate site• Food manufacturing: increased investment , stable employment.• Other manufacturing: some growth, no loss of major firm e.g. • Transport,/distribution: Significant airport expansion and distribution• CNDR developed by 2031. Southern Relief Road by 2051.• Large expansion of business and professional, digital and creative industries.
Next steps
Modelling under the three socio-economic futures scenarios looking at the impact of particular developments on the models.So far: Two Futures :"Future 1" is based on developing the Caldew Riverside site where it was planned to locate the University of Cumbria HQ and buildings
"Future 2" which is not likely at all includes a housing estate next to the motorway in addition to the Caldew development.
Depth and velocity have been modelled for these “Futures”.

Key drivers of future flood risk (Foresight: Future Flooding, Executive Summary)
Factors external to the local economy
• Global and national shock e.g. banking crisis and recession 2008-9• Regional and local shocks e.g.
Foot and Mouth Disease in Cumbria 2001Flooding in Cumbria and Carlisle 2005
• National and local policy decisions e.g. Govt. decision to grant Carlisle ‘Growth Point’ status. Cumbria and Carlisle Districts commitment to growth
• Private sector decisions: Regional and local government can plan but many plans can only be realised in partnership with private sector or by private sector alone
Conceptualising socio-economic change
Key factors are interrelated but relationships are complex and interactive
• Right employment opportunities needed to attract migrantsbut
• Critical mass of population needed to support services and businesses that will attract more people and investment
• Right type of housing needed to attract migrants and employees• Not all population growth will require employment opportunities e.g.
retirees, self-employed• Employment/housing may be located outside the area e.g. urban Carlisle
depending on propensity to travel to work
