The city has released an update on the actions it's taken so far to implement the recommendations of last month's independent review into the Highway 174 sinkhole.

An Ottawa man's car was swallowed by a sinkhole on the highway in September.

In December, the independent review on the Sept. 4 storm sewer collapse by B.M. Ross and Associates came up with five recommendations, including expanding the definition of a "high-risk storm sewer" to include consideration of the probability of failure as well as the consequences of failure, and to make physical inspections to supplement CCTV inspections, when feasible.

On Tuesday night, the city said implementing "many" of the five recommendations was already underway before the collapse, citing its Comprehensive Asset Management Program passed by council last October.

The city is creating a new enterprise asset management system for inventory information, and is enhancing its approach to risk assessment with "increased inspection protocols and monitoring in situations where a pipe is deemed to be in need of accelerated renewal, or to secure or stabilize any pipes and surrounding area during repairs."

The report also said city staff will be dealing with the provincial government to establish minimum inspection requirements for critical sewers, which aren't clearly defined.

The report will be tabled at an environment committee meeting on Jan. 15.

At the time, the city said it agreed with all five recommendations and was following up on them.
