Design Construction Impacts
Potential cost increases on the order of $7.1 million have been identified from factors including unexpected rock and soil conditions, requirements for additional retaining walls and application of new county road standards to planned frontage roads. Design work on the project is now examining whether the project’s goals can be met within the original cost envelope by alignment adjustments and reliance on an access plan that scales back the original plan for frontage roads. This work on the project to maintain its original cost expectation is being conducted with public review and input. Conclusions and recommendations will be reported as soon as possible. The advertisement date is expected to be delayed five to ten months.
