An internal email chain among Tetra Tech, Wayne County, Northville Township, and EGLE staff discusses a failed culvert on Napier Road near the Arbor Hills Landfill entrance, resulting in a road washout and closure. The correspondence covers permitting responsibility (likely GFL as applicant since it maintains that road segment under contract), possible FEMA disaster relief funding, and rerouting of landfill truck traffic via Six Mile Road during repairs.
Key data point: Wayne County closed southbound Napier Road between Five and Six Mile roads due to a culvert washout, rerouting landfill truck traffic onto Six Mile Road for an estimated two weeks or more (July 2021).

This is a formal U.S. Army Corps of Engineers wetland determination form completed for GFL's Arbor Hills Landfill in connection with a Napier Road culvert replacement project. It documents two sampling points: one upland site (UP01) found not to be a wetland, and one depression site (WP01) confirmed as a wetland based on hydrophytic vegetation, hydric soil, and wetland hydrology indicators.
Key data point: Sampling point WP01 confirmed as wetland (Prevalence Index 2.13, 100% hydrophytic dominant species); UP01 confirmed as non-wetland (Prevalence Index 3.91), surveyed 12/16/2021.

This is GFL Environmental's Joint Permit Application (JPA) to EGLE/USACE for a minor project to replace an undersized, failing culvert on Napier Road near the entrance to Arbor Hills Landfill, addressing chronic stormwater and heavy-truck-traffic-related road degradation. The project involves minor permanent impacts to a wetland (about 100 sq ft) and stream (about 809 sq ft below the OHWM) via installation of a larger precast concrete box culvert, with no mitigation proposed due to minimal impact.
Key data point: Proposed culvert replacement at Arbor Hills Landfill (Napier Rd) impacts approximately 809 sq ft of streambed and 100 sq ft of wetland, filed 4/27/2022 with a $100 minor project fee.
