Sewer Line Repair in Gresham, OR
Whoever owns a property in Gresham owns the lateral under it, out to the main. On iron, what that ownership eventually costs is decided at the bottom of the pipe. There are 32,249 occupied homes here, and across all the housing the median build year is 1983 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Corrosion along the invert is what a cast iron lateral does, and cast iron is the likely material beneath Gresham, whose housing typically dates from 1983. Lost bore reads as a blockage, and rodding does not restore it.

What went in the ground around 1983
A lateral laid in Gresham in that period is most likely cast iron on the house side and early PVC beyond it. Cast iron corrodes along the bottom of the pipe, so capacity is lost gradually rather than suddenly. More on cast iron laterals.
What a camera survey should settle here
On cast iron the recording should dwell on the bottom of the pipe, where corrosion channels and scale collect. The full picture on cast iron laterals.
Gresham is the 5th largest block of laterals we cover in Oregon, carrying about 3.0% of the 1,063,172 homes on our OR list, and its housing runs older than 53% of the OR towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
59% of homes here are owner-occupied — 2 points below the OR figure. That matters more on a lateral than on almost any other pipe in the house: the run from the building to the main is the property owner’s to repair, and a landlord and a resident owner do not find that out at the same speed.
Median household income across Gresham ZIP codes is $79,005 — the number to read against a repair that is the owner’s alone.

Before anyone digs in Gresham, get the run on camera — and ask what the bottom of the pipe looks like, because scale along the invert reads as a blockage. What the recording should show you.
