  2. Results of Phase 1 studies Heritage Oxford Archaeology and Archaeology South-East: desk-based research, field survey, geophysical survey & borehole survey. Key findings: • Nationally Important Building Resource • Nationally Important Historic Landscape Resource • Nationally Important Below Ground Archaeological Resource

  3. Policy Context • Scheduled Monuments - Ancient Monuments and Archaeological Areas Act 1979 (as amended) (‘the 1979 Act’) • Listed Structures - Planning (Listed Buildings and Conservation Areas) Act 1990 • Designated and undesignated heritage assets (Planning Policy Statement 5: Planning for the historic environment. 2010) • South Downs National Park Authority area

Options • The Baseline – Do nothing or do minimum • Option A – Partial breach managed realignment • Option B – Full breach managed realignment • Option C – Engineered reactivation of meanders and creeks • Option D – Maintain the existing defences • Option E – Sustain the existing defences – raise banks as sea level rises • Option F – Sustain the existing defences – raise banks by 300mm Assessment based on predictions by Capita over the short (0-20 yrs), medium (20-50 yrs) and long (50-100yrs) term

  8. Effects of Options • Engineering effects • Erosion effects (fluvial and/or tidal flow) • Inundation and/or burial by deposits • Vegetation changes • Effects on setting of heritage assets Positive effects Negative effects
