Remove silt fences, as the engineer determines, after stabilizing the slopes and ditches and developing the turf to the extent that future erosion i s unlikely. Clean up and restor e the surface after removal. The contractor owns all materials re maining after removal and is re sponsible for their disposal off the right- of-way. 628.3.4.2 Inspection and Maintenance

(1)Inspect all silt fences immediat ely after each rainfall and at least daily during prolonged rainfall.

Correct any deficiencies immediately. Additionally, review the locations for silt fences and filter barriers in areas that construction activity changed the earth contour a nd drainage runoff on a daily basis to ensure that the silt fences are p roperly and effectively locate d. If deficiencies exis t, install additional silt fences as the engineer directs or approves.

(2)Remove sediment deposits when t he build-up exceeds approximately 1/2 the volume capacity of the

silt fence. The engineer may order the contractor to remove dep osits if the engineer determines deposits exceed 1/2 the volume c apacity of the silt fence.
