Grassed areas must be reinstated using the original turf, replacement turf or an equivalent seed, depending on weather and growing season. In all cases, a reasonable growth must be established within the following 12 months.
Where grassed areas have been mown, the reinstated surface must be demonstrably free from stones greater than 20 mm nominal size. All other debris arising from the works must be removed from the site. It should be recognised that stones in grassed areas tend to migrate to the surface over a period of time and this should not lead to repeated intervention.
