Key document written by Alan Jemmett nearly 20 years ago about the consequences of wind blown sand accretion at Hoylake (see the executive summary):
Paper by Phil Smith and Patricia Lockwood about their work monitoring dune succession at Birkdale; a possible model for Hoylake as the conditions are so strikingly similar:
Drainage issues:

Key areas of concern are:
- Red Rocks to Kings Gap Slipway; broken domestic drains and sepage through promenade wall from private residences, notably end of Beach Road
- Kings Gap Slipway: water bubbling up, feeding meadow grass growth (which may be exacerbated by residents dumping sand back onto beach)
- Trinity Road Old Toilet Block Slipway: Multiple issues; potential incorrectly capped sewer, seepage through promenade wall; water bubbling from underground
- Full length of promenade: groundwater outlets blocked by raised sand levels (sand rising at 300mm per decade). Seepage through promenade wall.
