"[11] To retain the Fitties' status as a camp, it operates a strictly enforced 10-month year: "All chalets must be vacated from four in the afternoon to 9.30 the next morning throughout January and February."

[20] In 1901, the Parliamentary Committee of the Cleethorpes Urban Council discussed turning part of the land into a 'recreational facility', potentially as an extension of the golf links.

[23] During WWI, the Fitties' dunes were used by the army to build billets for soldiers stationed at the nearby Haile Sands Fort, from where anti-submarine chains with steel netting stretched to the south-east end of the coastline.

[24] In August 1914, the 3rd Battalion of the Manchester Regiment was stationed at the Fitties, training new recruits, rehabilitating injured soldiers and guarding the coastline between Cleethorpes and Tetney Lock.

In 1915, a picket – a small unit of soldiers, placed on a defensive line forward of a friendly position to provide timely warning of enemy approach – was located there.

[31] After WWII, a new layout and drainage system was put in place, together with shops and entertainment – including a mobile fish and chip van, mobile ice-cream van, donkey rides and the taking of "walkie pictures"[32] (more commonly known as 'walking pictures', commercial photographers would take photographs of people in the street, hand them a card inviting them to a kiosk later in the day to buy a souvenir photo).

[35] The Fitties became a hugely popular holiday destination, with a bungalow being a considerably cheaper option than a hotel or boarding house.

[39] A storm surge in 1953 caused the dunes to be breached by the sea, after which remedial action was taken to protect them, including "brush-wood kidding, fencing and marram grass planting.

[41] In 1958 due to the high risk of flooding the Fitties were deemed a "potentially dangerous area" by the Department of Scientific and Industrial Research.

Suggestions to improve safety included creating a "perfect flood warning system", the construction of a sea wall and more groynes[42] and planting of 2,000 Corsican and Scotch pines to "bind the soil".

[43] However, work was never started, for reasons of cost, and instead the council "agreed that people wishing to rent plots on the Fitties should be told of the risk.

"[44] In the same year, "picturesque water pumps" were replaced by taps,[45] a recommendation was made that roads be given names and bungalows numbers and 1,300 caravans were added to the 120 acres of land behind the dunes, creating further erosion.

£19,000 was spent on more sea defences, including a "low wall of slag over clay, with an asphalt walk on top" together with the purchase of a lifeboat and a loud-hailer.

Around 260 tonnes of broken concrete and slag was used to shore up the weakest points and suggestions were made to further increase its stability, including building a higher and deeper sea wall between the dunes and the camp site, together with a clay bank on the beach.

[73] A report commissioned in 1972 said of the Fitties, "Half-hearted commercial development has spoiled the natural area… Excessive vehicular and pedestrian pressure has caused considerable erosion.

In 1980, the Cleethorpes Council of Churches provided holidays in the Humberston Fitties for Vietnamese refugees who had arrived in England in late 1979.

[79] In 1986, Lord Delfont's "First Leisure Corporation", who already owned Blackpool Tower, was in discussion with Cleethorpes Borough Council to buy the Humberston Fitties for £6 million.

[80] The proposal was met by protests from chalet owners, with one issue being that the council hadn't offered them first refusal to buy their properties freehold.

[87] In October it was announced that Bourne Leisure had won the bid, which included a nine-hole golf course, tennis courts, bowling green and indoor swimming pool[88] and "eventually" 200 new caravans.

[93] By 1993, the Fitties' long beach became the site's biggest development, including new "fully-serviced pitches, tarmac roads, street lighting, electricity, water and cables for television and satellite", together with 7,000 trees.

The council launched a report which would "take a toothcomb over the site and its heritage, define what is a typical Fitties home… and look at what a conservation order can do to preserve the area's character."

"[101][102] In 1998, in order to further protect the Fitties, the council passed an Article 4 direction allowing authorities greater control over the area.
