Risk

Infrastructure Improvements Alternative Project Sequencing

• 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).
