1 Engineering solutions: Johnny Bulldog Lonning to Riverside Business Park The poor condition of the existing embankments in this area means new defences are needed: nearly 1km of clay cored earth embankment will be built. There will also be a new outfall structure from Durranhill Beck and repairs to the existing pumping station. R Eden situated north of map extent Existing pumping station Durranhill Storage Basin A69 Warwick Road Proposed works - Johnny Bulldog Lonning to Riverside Business Park From the Riverside Business Park, the defences will comprise a reinforced concrete floodwall with a landscaped bank (approximately 165m in length) followed by 90m of secant piled wall immediately downstream of Botcherby Bridge. A new access road to the rear of the defences will be built following construction. The new embankments will encroach on the Old Eden watercourse so it will be realigned. Options have discussed with English Nature; their preferred option is Option C, which requires the construction of a new confluence with the River Eden.

2 River Petteril Upstream of Botcherby Bridge On the right hand bank a clay cored earth embankment will be built, approximately 500m in length, set back from the watercourse to create an area for environmental improvements which will flood during time periods of high river levels. There may also be an opportunity to create a backwater feature to further enhance the local environment. On the left hand bank a low earth embankment will be built, approximately 500m long, and the footpath reinstatemed. Immediately adjacent to Botcherby Bridge, a low masonry floodwall will be built to maintain the flood defence.

3 Botcherby Bridge to Carlisle United Football Club (CUFC) Immediately downstream of Botcherby Bridge on the left hand bank the existing masonry wall will be repaired and the defence level of the masonry wall will be raised over a length of 70m. CUFC Training Botcherby Bridge to Carlisle United FC Following the raised wall, the defences will then comprise the rebuilding of a standard clay-cored earth embankment over a 60m length. Following the re-construction of the embankment the golf course and public footpath will be repaired. Next to the CUFC training facilities the existing embankments need rebuilding. However due to space restrictions between houses and the CUFC training ground, it is proposed that the existing embankment will be replaced with a 300m reinforced concrete floodwall. The next section of defence, adjacent to CUFC Brunton Park, comprises a reinforced concrete floodwall over a length of 350m. The car park in front of the defences will be relayed following construction.

4 Stony Holme Golf Club Here a 70m long reinforced concrete, brick-clad, floodwall will be built, with three vehicular and one pedestrian flood gate. The existing line of defence will be advanced by a few metres and the existing access ramps to the CUFC car park will be removed to reduce the visual impact for the resident of Stony Holme Cottage. The reinforced concrete floodwall will extend a further 70m to meet with the defence protecting CUFC Brunton Park. The access road to the CUFC car park will be rebuilt.

5 St Aidans Road, School Playing Fields and Catholic Lane Here a standard clay-cored earth embankment will be built next to St. Aidans Road, around the boundary of the Newman School playing fields, extending from high ground adjacent to the golf club to Catholic Lane over a distance of 700m. At Catholic Lane, the existing earth embankment will be removed and a reinforced concrete floodwall will be built over a length of 175m on the line of the existing bank. Catholic Lane will also be reconstructed to improve access and parking facilities. A standard, low-level, clay-cored earth embankment will be built next to Trinity School at the top of Catholic Lane. The defence length will be 110m and a ramp will be included to assist disabled access. Catholic Lane School playing fields St Aidans Road Extent of proposed works
