1.20 Sedimentation and Water Handling

Silts and fine materials introduced into water systems can have adverse effects to the aquatic environment. This construction Site is particularly sensitive due to its vicinity to fish habitat. Therefore, controlling sediment and run-off during construction work will be of high priority during this work. An interim construction water-settling pond or other sediment control measures shall be constructed and maintained by the Contractor during construction activities as deemed necessary by the Engineer.

The Contractor and environmental monitor shall ensure that water exiting the construction Site is free of sediments and other deleterious substances. All runoff leaving the site and entering water bodies, drainage courses, or drainage systems shall meet all applicable criteria and regulations.


Section 01561

Should these criteria be exceeded, construction will be stopped until the situation is rectified to the satisfaction of the environmental monitor and Engineer. The Contractor and environmental monitor shall control silt-laden runoff from the working and stockpile areas. This will involve utilizing a combination of several techniques on a site-specific basis as described below:

• Installations of upslope drainage interception to remove clean uncontaminated water and reduce amount of water flowing through the Site.

• Install additional erosion control measures such as check dams, hay bales, erosion control fencing in selected areas.

• Installation of cross-slope swales to enhance drainage and to prevent erosion of excavated materials.
