the Pegwell Bay toKingsdown coastlineThe frontage of the Pegwell Bayto Kingsdown coastline has twodistinct characters. To thenorth of Sandwich Bay Estatethe coast is characterised by anextensive dune system behinda sand and shingle beach. Thedunes narrow towards Dealwith low-lying agricultural landbehind. Most of the dunes areincorporated into three golfcourses, which attract a largenumber of visitors to the area.The residential area of northDeal is also low-lying.To the south of Deal the landbegins to rise to meet the cliffsat the southern end of thestrategy frontage. This stretch ischaracterised by residentialareas, with agricultural landfurther back. The shinglebeach is reinforced with formaldefences towards the south.The area’s close proximity tothe Continent has led to a richhistory in trade. Its historicbuildings and the Cinque Portof Sandwich has resulted in thearea becoming a populardestination for visitors, withnumerous facilities andrecreational activities both landand water based.The River Stour is tidal up toFordwich, approximately 17miles upstream. With itstributaries it drains aconsiderable part of the Kentcountryside, flowing throughthe urban areas of Canterburyand Sandwich.The area supports large areasof coastal habitats designatedwithin the Natura 2000network. These include sitesdesignated as SpecialProtection Areas (SPA), SpecialAreas of Conservation (SAC),Sites of Special ScientificInterest (SSSI) and NationalNature Reserves (NNR).4 Environment Agency Pegwell Bay to Kingsdown coastal strategy
strategic options for managingthe strategy areaThe coastal and river frontageswithin the strategy area havebeen divided into nine reachesreflecting the varying nature ofthe frontage and the specificissues affecting each reach.Reach 1: Cliffs End toStonar CutGenerally low lying coast andriver frontage sheltered fromwave energy by the extensiveinter-tidal mudflat area inSandwich Bay.Reach 2: Shell Ness toSandwich Bay EstateSand dunes fronted by a widesandy foreshore, which narrowstowards the southern end ofthis section. Shingle depositsoverlay the sand beach alongthe northern half of this unit.Reach 3: Sandwich Bay EstateThis residential area is locatedimmediately behind a concretebased revetment (bank)and thenatural shingle beach.Reach 4: Sandwich Bay Estateto Deal CastleBetween Sandwich Bay Estateand Deal flood protection isprovided by a colliery shaleembankment. Along the Dealfrontage this is replaced by aseawall and timber groynes. Ashingle beach providesadditional protection along thewhole of this frontage.Reach 5: Deal Castle toWalmer CastleThis frontage is characterisedby its wide and openshingle beach.Reach 6: Walmer Castle,Kingsdown and Oldstairs BayThe wide shingle beach atWalmer gradually reduces insize towards the south. Aconcrete seawall, timbergroynes and the shingle beachprotect Kingsdown. A groynedshingle beach and rockrevetment provide erosionprotection to the exposed areaof Oldstairs Bay.Reach 7: MoD Rifle RangeThe former Rifle Range at thefoot of cliffs is protected by aconcrete seawall.Reach 8: Sandwich andStonar LoopRiver frontage mainly protectedby earth embankments, withflood walls through Sandwich.Reach 9: Stour ValleyRiver frontage predominantlyprotected by earthembankments with floodplainson both banks.Strategic optionsThe strategy will set out how weneed to manage coastal andtidal flood and erosion risk forthe next 100 years. To do thiswe will consider for each of thenine reaches a range of optionsdescribed in the table below.Coastal strategyDo nothing – no furthermaintenance or repair workis undertakenDo minimum – emergencyrepairs undertaken asrequiredMaintain – maintaining theexisting defences in theircurrent formSustain – defences areraised and strengthened tosustain the current standardof protectionImprove – defences areimproved to increase thestandard of protectionManaged realignment –moving defences inland in acontrolled way to a moresustainable positionEnvironment Agency Pegwell Bay to Kingsdown coastal strategy 5
