4.0 Crossing Options
The objective is to install culverts at all the crossings. Each crossing has been marked and stream
locations have been staked during summer 2013 to facilitate location of the creek for winter culvert
installation. To ensure all creeks can be crossed 3 crossing options are proposed, this strategy is
being implemented to cover any unforeseen problems or issues that may be encountered.
Option 1 – Stream Simulation culvert as identified in Figure 1. It is planned and anticipated that all
crossings will be installed with culverts, however, if a temporary (1-2 weeks) crossing is required
before a culvert can be installed to move machinery; then,
Option 2 – A winter snow and ice bridge will be installed to allow for temporary passage of a creek. If
a culvert cannot be installed after temporary passage of a creek for some unforeseen reason; then,
Option 3 – A temporary MNR standard portable timber bridge using MNR Standard Abutment Design
installed with a Q25 opening will be used. A formal MNR application will be made with hydrology and
drawings as required.

5.1.2 Installation and Sediment Control Plan
• The winter installation of these crossings will be based on the MNR Guidelines for Culverts
Installed in the Winter (1996) a copy of which is found in Appendix A.
• The listed steps correspond to Figures 2 and 3 illustrating the installation and sediment control
plan. Prior to installation an onsite training course will be performed to describe:
• The values to be protected.
• How the control measures work
