Dierdorff v. Matthew Mahaffie, Whatcom County et al. did not have to happen.

We asked for a conversation about how a department that operates without meaningful accountability to the public or to those seeking to develop can be improved. We proposed something like an ombudsman function — a place where complaints can be addressed without retribution, where processing timelines are challenged, and where outcomes are measured and improved.

We received silence. And then a lawsuit became necessary — not just to right the injustices done to the Dierdorffs, but to expose the dangers of a department that answers to no one, yet can inflict financial damage, costly delays, and lasting disruption on anyone whose property it decides to regulate.

The Castlerock property wasn't a one-time windfall. The pattern extends to properties purchased by Mahaffie's girlfriend and his company — and to a personal mitigation bank worth over $500,000 that Mahaffie could offer to the very developers whose permits he controlled. The same regulatory power that made properties "unbuildable" was the same power that determined who could fix them.

In October 2024, Whatcom County Planning Director Mark Personius sent a threatening letter to a citizen who had shared information about the investigation. Not a correction. Not a denial. A threat. This is what government accountability looks like when the system is protecting itself — not the public.

Whatcom County Executive and the County Council have been copied on every document that forms the basis of our investigation at https://whatcomcorruption.com. We have spoken at public comment more than a dozen times. We did not arrive at this moment looking for conflict. We sought a meeting. We asked for something far short of nuclear — not the destruction of the planning department, not immediate bar complaints against the attorneys involved. We asked for a conversation about how to improve a department that operates without meaningful accountability to the public or to those seeking to develop. We proposed something like an ombudsman function — a place where complaints can be addressed without retribution, where processing timelines are challenged, and where outcomes are measured and improved.

We received silence. And then a lawsuit became necessary — not merely to right the injustices inflicted on the Dierdorffs, but to expose the dangers of a department accountable to no one, yet empowered to inflict financial damage, costly delays, and lasting disruption on anyone who seeks to develop in Whatcom County.
