Glass and metal caps are impossible to fully
remove and can cause significant injury
flat, straight and logical to ensure the maximum number of vehicles can be accommodated. In a tarmac car park. a car parking space is normally 2.4 x 4.8 metres. This would need to be enlarged significantly for turf - even with stewarded parking, most people don’t want to park close to another car. The grass should not be longer than 75mm, as there could be a fire risk in dry conditions, and the main routes either boarded or marked out. Disclaimers for damage to cars not being the landowner’s responsibility are essential to prevent costly claims.
The main damage will be surface loss of grass in the high traffic routes, possibly compaction and sometimes oil contamination. The difficulties occur in very wet conditions on heavy soils as vehicles can get bogged down leaving deep ruts.
The Event
It never ceases to amaze me the damage people can cause. Generally, with heavy foot or vehicular traffic, the grass is worn away and compaction occurs. Fortunately, this tends to be surface damage and can be alleviated by decompaction,
fertilisation and overseeding. Where drinks are available they should be in plastic bottles with plastic caps. Glass and metal caps are impossible to fully remove and can cause significant injury. Even so, plastic caps by the thousand can be pushed into the turf and need to be removed. This is the same for any other litter. The grass around concessions can be
only surface deep and overseeding, light rolling and possibly decompaction will be required
Effect of portable roadways on turf. The ruts are
scorched from hot drinks and diesel from generators. Where grass is damaged by hot water, drinks, etc. then reseeding the area is normally required. If there are diesel/petrol spills, then the effect will need to be assessed. There may be a requirement to notify the Environment Agency, especially if there is any risk of the pollutant entering a watercourse. Small spill can be treated with oil eating bacteria, or the soil replaced and the contaminated soil removed to a licensed landfill. Appropriate documentation will be required for this. Areas around portable toilets often get
sewage spills. This grass should be treated as toxic to health and ideally not used until sunlight has had about a month to kill off bacteria. The areas can be flushed with clean water. Serious spillages may again require the Environment Agency being notified. On a positive note, the nitrogen within sewage may help the grass to grow well!
Break down
Damage can occur as the site organisers are trying to get off site as quickly as possible. Similar problems can occur as for the set-up in terms of vehicle movements. The aim is to remove all items covering the grass as quickly as possible, but in a manner that is controlled and careful. I like to see the same team involved in the build
