SPECIFICATION FOR THE REINSTATEMENT OF OPENINGS IN ROADS
S9 Verges and Unmade Ground
S9.1 General
1) All backfill materials shall comply with the requirements of Section S5.
2) Existing top soil within 200mm of the surface shall be kept separate for subsequent re-use. Alternatively, an imported top soil may be used to a depth of 100mm or to match the existing depth of top soil, whichever is less.
3) The re-use of excavated materials as backfill material in verges and unmade ground is to be encouraged as part of a policy of environmentally sustainable construction.
S9.2 Adjacent Road Structures
1) Where road construction layers, structural courses, foundations, kerbs and/or backing providing edge support to road structures extend below adjacent verges or unmade ground, any reinstatement therein shall take account of such provisions. The reinstatement of such areas shall match the existing layer thicknesses, with similar or equivalent materials.
2) Where there is no such edge support within adjacent verges or unmade ground, any reinstatement within 600 mm of the edge of a road shall include sub-base materials at backfill level up to a 45° fall line extending downwards from the road surface at the nearest point to the reinstatement, as shown in Figure S9.1.

S9.3 Cultivated Areas
Unless otherwise agreed, cultivated areas containing shrubs, plants or bulbs shall be reinstated using the same or similar species. Thereafter, a reasonable growth shall be established within the following 12 months. Where the Authority knows of special features in verges (e.g.: orchid sites etc.) it should inform the Undertaker in order to agree the best means of conserving the special features.
S9.4 Grassed Areas
1) Grassed areas shall be reinstated using the original turf, replacement turf or an equivalent seed, depending on weather and growing season. In all cases, a reasonable growth shall be established within the following 12 months.
2) Where grassed areas have previously been mown, the reinstated surface shall be demonstrably free from stones greater than 20mm nominal size. All other debris arising from the works shall be removed from the site. It should be recognised that stones in grassed areas tend to migrate over a period of time and this should not lead to repeated intervention.
S9.5 Verges, Ditches and Drainage Courses
Verges, ditches and drainage courses shall be restored to their original profile, unless otherwise agreed.
