Risk 7. a) 2. Attachment Approved Project Sequencing Public Safety and Liability - roadway remains in a safe and passable condition - inspection and monitoring; regular and routine patrols - respond immediately to repairs or maintenance existing infrastructure Timing of Infrastructure Improvements - Rock fill widening and stabilization - 2019/2020 - Pavement & maintenance repairs; road enhancements – 2021 - Chemong Bridge rehabilitation - 2022 Procurement and Contractual Issues - No issues Regulatory Approvals - DFO approvals pending

Risk 7. a) 2. Attachment Alternative Project Sequencing Infrastructure Improvements - Rock fill widening and stabilization – deferred to 2039 - Pavement & maintenance repairs – 2019 - Road enhancements – deferred to 2039 - Chemong Bridge rehabilitation - 2022 Procurement and Contractual Issues - Inflationary cost impacts due to deferral of widening and stabilization - Expenses already incurred under current contract - Renegotiation of major contract - If unsuccessful, potential revoking of contract - Potential for litigation against the County. Regulatory Approvals - DFO approvals may be not required to complete maintenance and enhancements. - DFO approvals would eventually be needed for any in-water work (2039).
