Replacement of main sewer line on rental property

[hslettel]

I had to replace the main sewer line on a rental property in California and I'm not clear on whether this is considered an improvement or repair. It was about $14,000 dollars. I've seen a couple of other posts on this question, but the responses were somewhat conflicting. I want to make sure I record it properly. It appears it should be recorded as a Land improvement asset for depreciation, but perhaps there is a still a one-time depreciation allowance that would allow me to expense it all at once?

The sewer line replacement costs is classified as a land improvement and depreciated over 15 years under the MACRS GDS depreciation schedule. See IRS Pub 946 at https://www.irs.gov/pub/irs-pdf/p946.pdf on page 97, item 00.3 - Land Improvements.
