PORTLAND, Ore. -

Contractors are busy repairing sidewalks in Portland's Irvington neighborhood in response to hundreds of complaints, even though some residents say the sidewalks weren't that bad.

KGW reports it made a public records request and found out that most complaints were made by one man -- 300 in April alone.

City Bureau of Transportation spokeswoman Diane Dulken says it doesn't matter who makes a complaint. The city ensures that sidewalks don't pose a hazard to the public. The city forces homeowners to pay for the repairs.

The man making all the complaints wouldn't explain his motive to KGW, but some neighbors suspect he's a contractor looking to drum up work.
