7. Investigate the costs and benefits of traditional, hard engineering.

Hard engineering used at Lyme Regis
1. Sea wall bulit along Marine Parade - built to relect the energy of the waves, so they do not erode the base of the cliff. £2000 per metre. At Lyme Regis they chose to build a sea wall that is not very high so that tourists could easily access the beach. Most people think its appearance is pleasing and it provides excellent access to the beach front as it has a promenade running along its top.

However during the storms of January and February 2014 there was damage along Marine Parade and questions were asked about  why the sea wall wasn't built higher.
