Culvert Monitoring Report GMT2/MT7 Spring Breakup 2020

The objective of the GMT2/MT7 culvert monitoring program is to monitor and document culvert performance and to evaluate areas where additional culverts or modifications to existing culverts are necessary to maintain natural drainage. This meets the hydrology monitoring requirements set forth in permitting and requires annual GMT2/MT7 access road culvert monitoring reports to be submitted for three years post-construction. This is the second year of post-construction reporting.

The following tasks were performed to meet the permit requirements:

• Aerial and ground photo documentation of the GMT2/MT7 access road and pad to demonstrate hydraulic connections during spring breakup and post breakup (summer) conditions

• Identification of areas of differential ponding (ponding on one side of the road), drying, erosion, or stream channel changes adjacent to fill areas

• Demonstration of culvert conveyance of surface water flow based on the maintenance of natural drainage patterns and lack of evidence to the contrary (ponding, drying, erosion, stream channel changes)

• Evaluation of all areas where additional culverts are necessary to maintain natural drainage patterns

• Evaluation of all areas where culvert maintenance, repair, upgrade, setting adjustments, or replacement are necessary to maintain natural drainage patterns
