Council Meeting

Agenda Report # 45
TO: Mayor and Council
SUBJECT: Riverwalk Damage
INITIATED BY: David Arrington, Deputy City Manager
Recommendation: Approve the resolution authorizing the City Manager to
enter into an agreement with Uptown Columbus, Inc. to perform stabilization of
the river bank and repairs to the Riverwalk north of City Mills and to perform
necessary repairs forthe boat landing behind the Trade Center.
Background: On Wednesday March 20, 2013 it was reported a section of the
Riverwalk had collapsed north of City Mills. An inspection of the area
revealed an area of approximately 900 feet in length had been impacted by
movement of the river bank. Approximately 300 feet of the Riverwalk received
major damage making it impassable and dangerous to the public. The Riverwalk
has been closed from the 23rd St. Pavilion to City Mills. The damaged area is
located immediately behind Chase Homes. Public Works has installed fencing in
the area to keep the public from the hazardous area.
Analysis: City staff met with Jacobs Engineering, our engineering consultant
and representatives from Scott Bridge on site to assess the damage and develop
a strategy to move forward. Scott Bridge is the contractor working for
Uptown, Inc. on the River Restoration project and is currently working below
City Mills. Based on the initial assessment by our Engineering staff and our
consultant, it is our recommendation to move forward immediately with
stabilization of the riverbank and repairs to the Riverwalk using a
design-build approach. It is our recommendation that the City contract with
Uptown, Inc. to have their contractor Scott Bridge work with our consultant
Jacobs Engineering on designing and implementing a riverbank stabilization plan
and repairs to the Riverwalk. Scott Bridge has access material on the City
Mills site that will require disposal and this material could be used for bank
stabilization resulting in a significant savings for the City. The
design-build approach would provide for the most timely stabilization and
repair of the damage, preventing further damage to the Riverwalk and allowing
it to be reopened to the public. At this time, the cost of the stabilization
and repairs can not be estimated since a design has not been completed.
However, Scott Bridge has agreed to contract with Uptown for time and materials
on the project. The City's Project Managers can closely monitor this work and
the expenses associated with the project.
There is another area along the Riverwalk that has sustained significant damage
recently that is in need of repair. The boat landing behind the Trade Center
has a large section of the ramp that has collapsed. The damage represents a
hazard to the public. The boat landing is also the take out point for
Whitewater operations scheduled to begin on Memorial Day. The Uptown
contractor, Scott Bridge will be in the area making ramp improvements within
the next few weeks. It would take 60-90 days for the City to bid the work and
to authorize a contractor to perform the necessary repairs. I would recommend
we add this work to the previously mentioned agreement with Uptown to allow
Scott Bridge to perform the work while they are working on the ramp making
improvements to the take out point.
Financial Considerations: The financial impact of the repairs has yet to be
determined. Staff will provide an engineering estimate to Council as soon as
one is available.
Projected Annual Fiscal Impact Statement: No annual fiscal impact is
anticipated. Maintenance of the area is already a budgeted expense.
Legal Considerations: Council must authorize repairs to Riverwalk property.
Recommendations/ Actions: Approve the resolution authorizing the City Manager
to enter into an agreement with Uptown Columbus, Inc. to perform stabilization
of the river bank and repairs to the Riverwalk north of City Mills and to
perform necessary repairs the boat landing behind the Trade Center.
