Policies - Shoreline Management PlansCrosby Marine Park to Hall Road, CrosbySMP recommended policy "Hold the Line" The main coast management problem at Crosby is the accumulation of sand in the bay centred on Mariners Road. This is a natural phenomenon, almost impossible to control, that leads to large amounts of sand being blown from the beaches onto the closely surrounding roads and residential area. Management work has been undertaken to reduce the sand blow by encouraging dune growth seaward of the Crosby Promenade and by stabilising the planted areas of the Marine Park. Constant future attention will be needed to maintain and improve on these preliminary management efforts. The Crosby concrete sea walls were built in two phases:- from Seaforth Dock to Mariners Road in 1970-72 and from Mariners Road to Hall Road West in 1974-76. The first and earlier phase is at a higher level, is more massive, and has suffered less storm damage than the second phase. The section north of Mariners Road includes a 900 metre length of timber revetment near Hall Road, dating from the 1960's, incorporated within the 1975 concrete structure. In the vicinity of Hall Road, the level of the defence is insufficient to prevent wave over-wash during occasional severe storms. This causes periodic damage to the pedestrian and car park surfaces and the backing amenity grassland. Plans for any future reconstruction should consider the need to provide an increased level of protection.
