At a news conference on March 27, Mayor John Cranley, City Manager Patrick Duhaney and Department of Transportation & Engineering Director Joe Vogel highlighted plans to address hillside stability on Columbia Parkway between Bains Street and Torrence Parkway.
Several landslides have occurred in multiple locations along this 5,100-foot stretch since mid-January, prompting near-continuous emergency lane closures.
Mitigation is expected to take up to two years to complete and will cost an estimated $17 million.
The City has begun the process to obtain contractor bids to perform the stabilization work.
DOTE engineers recommend using an expedited two-step design-build delivery method consisting of a Request for Information (RFI) followed by a Request for Proposal (RFP). The RFI process will allow design-build teams to submit their best and most cost-effective design concepts, preliminary plans, and cost and time estimates for consideration.
After DOTE evaluates the plans from the RFI, teams will be short-listed and invited to submit a more detailed RFP. The City will use its emergency procurement procedure to allow work to begin while negotiations are ongoing.
Actual construction is expected to take approximately 18 to 24 months to complete.
At least two lanes of the parkway will need to be closed between Bains and Torence for the duration of the project.
