Document/Issue | Mitigating Measure/Commitments/Recommendations from EA | Implemented(Yes/No) | Action Summary Reference Nos. | Additions/Exceptions |
Site Inspection and Monitoring | An environmental inspector experienced in working around watercourses will be responsible for inspecting the erosion and sediment control measures and identifying deficiencies. | Yes | AS2 | |
The inspector will also assess all of the other general mitigation measures to ensure they are implemented as intended. | Yes | AS2 | |
The inspector will ensure all environmental mitigation and design measures are properly installed/constructed and maintained, and appropriate contingency and response plans are in place and implemented if required. | Yes | AS2 | |
For any works requiring channel realignment, appropriate specialists (fluvial geomorphologists, fisheries biologists) will be used. They will also be responsible for obtaining specialist advice (e.g., hydrology/hydraulics, fisheries) as required during the construction of the new channel. | Yes | AS4 | |
Post-construction monitoring is typically prescribed in the federal Fisheries Act Authorization and the terms and conditions of this authorization will be met. | Yes | AS9 | |
Post-construction monitoring, if prescribed, will determine the effectiveness of environmental protection and compensation measures identify problem areas and recommend corrective measures. | Yes | AS9 | |
Clearing by use of industrial equipment | Design and install native woody riparian vegetation groundcover seed mixes to pre-construction conditions or better for the channel realignment at Broadway Drain. | Yes | AS4, AS8 | |
Potential bank instability and exposed soils. | Newly created channels will be stabilized with groundcover seed mix, erosion control blanket, vegetation plantings and rock treatment to prevent/minimize erosion. | Yes | AS2, AS8 | |
Stabilize and revegetate all disturbed flood plain areas. | Yes | AS2, AS4 | |
Design and implement temporary erosion and sediment control measures (e.g. silt fence, etc.) to minimize erosion of exposed soils during construction until site is stabilized. | Yes | AS2 | |
Potential bank instability and exposed soils from grading of highway fill embankment, flood plain and channel realignments. | The newly created channel of Broadway Drain, including banks, will be stabilized with groundcover seed mix, erosion control blanket, vegetation plantings and rock treatment to prevent/minimize erosion. | Yes | AS4, AS8 | |
Design and implement erosion and sediment controls to prevent erosion of exposed soils and migration of sediment to watercourse. | Yes | AS2, AS4, AS8 | |
Rehabilitation of exposed soils/surfaces (stabilize and re-vegetate). | Yes | AS2, AS8 | |
Store, handle and dispose of all excess fill materials in a manner that prevents their entry to the watercourses. | Yes | AS2 | |
Changes to slopes and drainage (flood plain, high slopes, new channel). | Rehabilitate exposed soil surfaces that drain to the watercourses, including the channel bed and banks of the watercourse. | Yes | AS2, AS4, AS8 | |
Design drainage system and stable slope grades within floodplain and realigned channel of Broadway drain to mimic overland drainage patterns and runoff contribution to the watercourse. | Yes | AS4, AS8 | |
Addition or removal of instream organic structure by placement of fill material. | Design and install instream cover habitat elements (overhanging vegetation, boulders, etc.) in channel realignment of Broadway Drain to replace those removed from proposed works and enhance the newly created channel. | Yes | AS4, AS8 | |
