• e) We recommend that the existing grass areas adjacent to the drain be protected as part of this project. These grass areas reduce the amount of erosion and the sediment entering the drain and enhance water quality.

• f) Since all of the work will be carried out at the existing or new driveways, and is primarily within the road allowance and limits of the drain, and because full restoration will be provided, we find that there is no requirement for damages or allowances pursuant to Sections 29 and 30 of the Drainage Act.

We recommend that the Cahill Drain – Upper Part be repaired and improved, in accordance with this report, the attached specifications and the accompanying drawings, and that all works associated with same be carried out pursuant to Section 78 of the “Drainage Act, R.S.O. 1990, Chapter D.17 as amended 2010”.
