Lyme Regis Case Study of Coastal Management

Overview

  • Location: Lyme Regis is a small coastal town on the south coast of England, part of the Jurassic Coast, a World Heritage Site known for its fossils.
  • Importance: Popular tourist destination.

Reasons for Coastal Management

  • Erosion: High rates due to high energy waves and geology.
    • Geology: Combination of limestone (resistant) and clay (vulnerable).
    • Threats: Risk of landslides endangering houses, roads, and farmland.
  • Tourism Impact: Decrease in tourist numbers due to lack of beaches.

Coastal Management Strategy

  • Plan: Lyme Regis Environmental Improvement Scheme.
    • Consultation: Included residents, fishermen, and environmentalists.
  • Harbour Dredging: Annual dredging with sand used for beach replenishment.

Phases of Coastal Management

  • Phase 1 (1990-1995):

    • Sea wall and promenade construction.
    • Emergency cliff stabilization in 2003-2004 using nails and improved drainage.
  • Phase 2 (2005-2007):

    • £22 million investment in seawalls, promenades, sand and shingle beach.
    • Extension of rock armour for harbour wall protection.
  • Phase 3: Not undertaken due to cost-benefit analysis.

  • Phase 4 (2013-2015):

    • £20 million project for a 390m sea wall and cliff stabilization.
    • Installation of long nails and mesh for cliff protection.

Effects of Coastal Management

Positive Impacts

  • Aesthetic Improvement: Increased attractiveness and tourism.
  • Protection: New defences withstanding storms, better harbour protection.

Negative Impacts

  • Increased Traffic and Litter: Due to higher visitor numbers.
  • Natural Landscape Impact: Perceived spoilage by some residents.
  • Interference with Coastal Processes: Potential conflicts with neighbouring coastlines.
  • Fossil Reduction: Reduced landslides lead to fewer fossils.
