On March 19, 2017, City staff responded to reports of a sinkhole on Yorba Avenue between Chino Avenue and Riverside Drive.  Staff located the sinkhole in the northbound lane on the north side of the Union Pacific Railroad (UPRR) crossing.  City staff removed the pavement damaged by the sinkhole and installed steel plates to protect and cover the sinkhole.  It was determined that the road was unsafe for north and southbound vehicular traffic through the UPRR crossing; therefore, staff immediately closed the road to through traffic.  Following the road closure, staff began coordinating with UPRR to investigate the sinkhole, determine the extent of the damage, and recommend a repair to reconstruct damaged infrastructure.




Staff has been coordinating with UPRR to determine how to reconstruct all infrastructure damaged by the sinkhole.  The recommended repair project involves excavation, removal of an existing UPRR culvert, backfill with cement slurry mixture, and the reconstruction of roadway and UPRR tracks.  The total cost of design and construction of this project is estimated to be $196,000, which includes 10% for project contingencies.


A cooperative agreement was developed to outline the responsibilities and obligations of each agency for the construction of this project. The City’s fair share contribution to the project was determined to be 50% of the total cost estimate, or $98,000 including $9,000 for project contingencies. The City Attorney has reviewed the cooperative agreement and forwarded the same to legal counsel for UPRR for review and approval. The City is awaiting authorization of the cooperative agreement from UPRR.


Upon completion and acceptance of this UPRR repair project, the City will reimburse UPRR for 50% of the actual costs incurred during the construction/repair project for an amount not to exceed $98,000.
