This document summarizes findings from an ongoing investigation by Real Issues Podcast into the conduct of Matthew Mahaffie, a Natural Resources Planner for Whatcom County Planning and Development Services (PDS), and the county's subsequent response to documented complaints. Recipients are invited to comment before publication. A seven-day response deadline applies from the date of transmission.
This is not a complete account of all findings. It is a summary of documented, verifiable facts drawn from public records, county permit files, MLS records, financial records, court filings, and Whatcom County's own investigative reports.
Section 1: The Targeting
One Lot. One Owner. One Outcome No Neighbor Received.
The Greens at Loomis Trail is a residential subdivision in Blaine, Washington, established through permit LSS1994-00004 with supplemental mitigation permit MIT2003-00021. As part of the original platting process, the developer conducted extensive wetland mitigation — filling wetlands, planting native vegetation, establishing conservation easements, and reducing all wetland buffers to 25 feet along residential lots. That mitigation was completed, monitored, and approved by Whatcom County. The result was a recorded plat with developable residential lots whose wetland obligations had already been discharged.
Homes were built throughout the subdivision without extraordinary critical areas requirements. Lots developed from approximately 2008 through 2015 were permitted without the mitigation, reasonable use exemptions, or variance processes that would later be imposed on the Dierdorff family. In 2017 and 2018, at least two lots in the immediate vicinity were processed simultaneously. The contrast in outcomes is documented in the county's own permit files.
Dierdorff — 4470 Castlerock Drive — CA2017-00214
Application Date: June 2017
Reviewer: Matthew Mahaffie, Natural Resources Planner
Finding (July 28, 2017): "The property is fully encumbered by wetland buffer and a reasonable sized home cannot be placed on the property."
Result: 18-month ordeal. Application lapsed. Owner sold October 2020 for $80,000.
Bhullar — 4348 Castlerock Drive — CA2018-00304
Application Date: 2018
Reviewer: Joshua Fleischmann, Natural Resources Staff
Site Inspection: July 18, 2018
Finding (July 19, 2018): "Staff conducted a site inspection and did not identify regulated critical areas and/or buffers that would be impacted by the proposed development."
Result: Cleared. No mitigation required. Permit proceeded.
Same subdivision. Same street. Same plat. Same underlying 2002 mitigation. One year apart. Two opposite outcomes — one reviewed by Mahaffie, one not. The Dierdorff lot was the last unbuilt lot in the subdivision. Mahaffie knew the correct determination. He watched a colleague make it on a neighboring property while the Dierdorff application was dying under his signature.
Section 2: The Concealment Structure
The LLC, the Proxies, the County Address, and the Missing Disclosures
The transactions described in this report were not conducted transparently. Each one involved structural choices — a newly formed LLC, family members and a girlfriend as nominal purchasers, county resources used for private permit work, and real estate agents representing both sides without meaningful disclosure — that together paint a picture the investigation never examined.
Dead Goat Properties LLC: Created for This Purpose
Dead Goat Properties LLC was formed on February 7, 2019. Its governor is Matthew Mahaffie. Its registered agent is Reta Stephenson — Mahaffie's mother — at 909 Alderwood Lane, Sedro Woolley.
The Blaine Road purchases closed in April 2019 — 60 days after the LLC was formed. A Skagit County property at 22788 Grip Road was purchased February 11, 2019 — four days after formation. Dead Goat was not an existing entity that happened to acquire properties. It was created to acquire them, by a county Natural Resources Planner who regulated the type of properties it was buying.
Haggard noted the LLC's existence. She did not ask why it was formed when it was, what role it played in shielding Mahaffie's identity from sellers, or what the relationship was between Mahaffie's regulatory position and the entity he used to profit from it.
The Proxy Purchasers
On the Blaine Road transactions, Mahaffie structured the purchases to avoid his name appearing as a buyer:
8358 Blaine Road was purchased by Lara Kratzer — Mahaffie's live-in girlfriend — not by Mahaffie or Dead Goat.
8366 Blaine Road was purchased by Dead Goat Properties — governed by Mahaffie, with his mother as registered agent.
Kratzer and Mahaffie shared the same home address. Dead Goat's mailing address was also their shared home.
The seller, Miguelina Beckwith, was dealing with buyers who presented as a young woman and an anonymous LLC. She had no reason to know that the person directing those purchases was the county regulator whose expertise in wetland properties gave him decisive knowledge of exactly what those properties were worth and what they could become.
Mahaffie's Name and County Address on the Permits
Despite not being the legal owner of 8358 Blaine Road, Mahaffie placed himself at the center of its permitting process — using county resources to do so.
The On-Site Sewage System permit application for 8358 Blaine Road, dated January 14, 2019, lists the applicant as "MATT MAHAFFIE." The mailing address on the application is "c/o 5280 Northwest Drive, Bellingham WA 98226" — the address of Whatcom County Planning and Development Services. Mahaffie used his employer's address on a permit application for a property owned by his girlfriend.
The email record is equally explicit. On June 3, 2021, Mahaffie emailed the septic system designer from his personal email account (mahaffim@hotmail.com), attaching the wetland delineation report for 8358 Blaine Road and advising on the septic design: "Finally got the wetland work on paper for this parcel's septic design that Phil had asked for... Hopefully this will be sufficient to get this design approved. Let me know if you have any questions or need anything else."
On June 9, 2021, when asked whether mitigation would be required, Mahaffie replied: "Yes, mitigation will be provided... If I need to work it through with Phil, no biggie." He was casually offering to route the permit through his own department — for a property owned by his girlfriend.
The wetland delineation for 8358 Blaine Road was submitted June 3, 2021 and approved June 24, 2021 — 21 days. Haggard made no attempt to determine whether this processing time was normal, expedited, or extraordinary compared to other applications reviewed by the same department in the same period.
What the Real Estate Agent Was Told
Washington's Real Estate Agency Disclosure Law (RCW 18.86) requires buyers to deal honestly and disclose material facts. Mahaffie told the real estate agent on the Blaine Road transactions that he "worked for the county."
He did not disclose that he was a Natural Resources Planner — the county employee whose professional determinations decide whether wetland properties like the ones he was buying are buildable, what mitigation they require, and what they are worth to informed buyers. That distinction is not semantic. It is the entire source of his advantage in these transactions.
What Mahaffie disclosed to sellers and agents about his role does not require an outside source — it is documented in the investigation report itself. Mahaffie told the investigator he deliberately sought properties where “less knowledgeable purchasers might give up” because of wetland complications. Haggard confirmed this as undisputed fact, writing: “It is undisputed that Mahaffie used his knowledge of wetlands regulations to spot potential bargains.” What neither Mahaffie’s testimony nor the investigation ever examined is what he disclosed to sellers and agents about the specific nature of that advantage. There is a material legal and ethical difference between “I work for the county” and “I am the Natural Resources Planner whose professional determinations govern whether wetland properties like this are buildable and what they are worth.” The first is technically accurate. The second is what would have been material to every seller and every agent in these transactions. Mahaffie’s own words confirm he understood his advantage precisely and deliberately sought out sellers who did not share it. The investigation never asked whether he disclosed it.
Dual Agency Without Meaningful Disclosure
Both the Castlerock and Blaine Road transactions involved dual agency — a single real estate agent representing both buyer and seller. Haggard called both transactions "arms-length" without interviewing either real estate agent.
Castlerock: Rodney Helgeson represented both the seller (Dierdorffs) and the buyer (Dead Goat Properties/Mahaffie) in a Sold-Unlisted transaction that never reached the public market. The Dierdorffs had no independent representation. The agent whose fiduciary duty was to maximize their sale price was simultaneously serving the buyer whose goal was to minimize it.
Blaine Road: Rob Merhaut began as Beckwith's listing agent — with a fiduciary duty to get her the best price — then converted to dual agency, representing both Beckwith and the buyers (Kratzer/Dead Goat/Mahaffie). Beckwith was an elderly widow who had been unable to sell her properties. Her own agent became the agent of the buyer she was trying to find.
Washington's dual agency disclosure requirements (RCW 18.86.060) require informed written consent from both parties after full disclosure of the agent's obligations to each. The question the investigation never asked is what "informed consent" means when one party to a dual agency is a county regulator with expert knowledge of wetland property values and the other is an elderly seller who couldn't move her properties and didn't know the buyer was the man who determines whether such properties are buildable.
Haggard described both transactions as arms-length. She never asked either agent what they disclosed or when. She never asked whether Mahaffie disclosed his regulatory role. She never asked what Beckwith was told about who was buying her land. She accepted Mahaffie's characterization of both deals as fair and ordinary without verifying a single aspect of it.
Section 3: The Castlerock Scheme
Buy Low Using a False Finding. Sell High Using the Truth He Withheld.
The financial math of the Castlerock transaction is straightforward. Its significance lies in what sits on either side of the numbers.
2007: Dierdorff family purchases 4470 Castlerock Drive for $150,000.
June 2017: William Dierdorff applies for natural resource assessment CA2017-00214, seeking to establish a building footprint. The application is assigned to Matthew Mahaffie.
July 28, 2017: Mahaffie issues his NOAR. The property is "fully encumbered by wetland buffer." A "reasonable sized home cannot be placed on the property."
2017–2019: Eighteen months of permitting. In March 2019, the county notifies the Dierdorffs their application has expired.
August 2019: Buyer Brady Mason contracts to purchase at $150,000 — the Dierdorffs' original purchase price. Mason hires AJ Bredberg, who submits a mitigation plan directly to Mahaffie in October 2019. Mason then abandons the contract. No documented explanation.
October 2020: Dead Goat Properties, through Rodney Helgeson acting as dual agent for both buyer and seller, purchases 4470 Castlerock Drive for $80,000. Sold-Unlisted — never publicly marketed. Comparable properties sold for $140,000 in 2018. County assessed value: $120,000. Mahaffie paid 43 percent below market comparable.
The Dierdorff Loss
Original purchase (2007): $150,000
Sale to Mahaffie (2020): $80,000
Gross loss on sale: $70,000
Taxes, HOA, fees (13 years): ~$50,750
Total documented loss: ~$120,750
April 2022: Mahaffie lists for $229,000 through the same broker, Helgeson. Helgeson tells other agents: "My understanding from the seller is that all the wetland mitigation was done as part of the original plat with permanent buffers of 25 feet." Helgeson directs buyers to contact Amy Dearborn at the county for confirmation. This is what Mahaffie told his listing agent in April 2022. It is the opposite of what he told the Dierdorffs in July 2017.
April 22, 2022: Buyer #1 walks at 1:28 PM after 10 days in feasibility. On this same date, an unsigned memorandum appears in PDS files. (See Section 5.)
April 26, 2022: The Bulanovs enter feasibility four days later.
May 18, 2022: Bulanovs remove feasibility contingency after 22 days — more than twice Buyer #1's duration.
July 13, 2022: Dead Goat closes with the Bulanovs at $229,000.
June 2023: Bulanovs apply for building permit. Nathan Goldschmidt's NOAR: "Any potential impacts to wetlands and wetland buffers were previously mitigated for in the approval of the platted development." Zero mitigation required. A 4,013 sq ft home is built and occupied today.
Mahaffie's Profit
Purchase (October 2020): $80,000
Sale (July 2022): $229,000
Gross profit: $149,000
Improvements: $0
Holding period: 21 months | Return: 186%
Section 4: The Blaine Road Transactions
What Haggard Accepted. What the Financial Records Would Have Shown.
The Transaction Structure
In April 2019, Dead Goat Properties (8366 Blaine Road, $10,000) and Lara Kratzer (8358 Blaine Road, $70,000) purchased two adjacent 7-acre parcels from Miguelina Beckwith. Both had agricultural tax designations Beckwith was not using. The sale triggered removal of those designations, generating back taxes on both parcels.
What Mahaffie Told the Investigator
Mahaffie told Haggard he paid $23,854.70 in back taxes — and that this amount should be added to the $80,000 purchase price, making his effective investment $103,000. Haggard published this characterization. She never requested a settlement statement.
What the Records Show
The Whatcom County Assessor records and the Notices of Removal of Current Use Classification — public documents — tell a different story:
For 8358 Blaine Road: the county assessed $12,560.80 in back taxes (Haggard report) / $12,866.64 (Grifo complaint). The removal notice names Miguelina Beckwith as the property owner who filed it. Beckwith paid.
For 8366 Blaine Road: the county assessed $11,293.90 in back taxes (Haggard) / $11,587.90 (Grifo). Same result — Beckwith filed the removal notice and paid.
Beckwith received $10,000 from the sale of 8366 Blaine Road and paid more than that amount to reclassify the property. She did not net a dollar. She lost money to complete the transaction.
On 8358 Blaine Road, the $20,000 cash at closing was consumed by back taxes and closing costs. Beckwith's net cash was effectively zero. She held a $50,000 promissory note of unknown terms — which Haggard also never examined.
One Document Would Have Resolved This
A settlement statement — the most basic document in any real estate transaction — shows line by line who paid what. Haggard never requested it. Mahaffie's claim that he paid the back taxes is contradicted by the seller's own public tax records. An investigation that requested the settlement statement would have known this within minutes.
What 8366 Blaine Road Is Now Worth
Dead Goat Properties purchased 8366 Blaine Road for $10,000. Its assessed value is now $189,122. No improvements have been made. The appreciation is the product of what Mahaffie knows.
In 2022, Mahaffie signed an agent authorization allowing Royal Emerald Motors — a business his department regulates — to use 8366 Blaine Road as an offsite wetland mitigation site. Mahaffie would sell an easement for wetland enhancement on his property. Mitigation credits in this area are valued at approximately $350,000 per acre. At 7.5 acres, the potential mitigation credit value is in the range of $2.6 million.
Planning Director Mark Personius reviewed this arrangement. His conclusion: county policy does not preclude employees from buying, selling, and developing property. He did not address whether a county regulator using insider knowledge to acquire a property at below-assessed value from a seller who lost money on the transaction — then positioning it to generate millions in mitigation credits from a business his department regulates — violates RCW 42.23.070's prohibition on using public position to secure special privileges.
Personius's name appears on the letterhead of the April 22, 2022 memorandum discussed in Section 5.
Section 5: The Magic Memo
A Document Nobody Wrote, Nobody Requested, Nobody Distributed — But That Changed Everything
On April 22, 2022, a memorandum appeared in Whatcom County PDS files, on the letterhead of Mark Personius, AICP, Director of Planning and Development Services.
Its subject: "Critical Area Regulated Buffer Status for 'The Greens at Loomis Trail.'"
Its finding: that lots in the Greens at Loomis Trail are exempt from further critical areas review because the 2002 plat mitigation fully discharged all wetland obligations. "No further critical areas review under WCC 16.16 Articles 6 & 7 would be required for any and all lots within this plat."
This memo establishes precisely the legal position that Mahaffie's listing agent was communicating to buyers that same month, that Nathan Goldschmidt applied when approving the Bulanov permit in 2023, and that the county's own investigator later called legally questionable — without ever acknowledging the memo existed.
The PRR Response
In March 2026, in response to a public records request about the memo's origins, Whatcom County's Public Records Officer responded in writing:
"PDS does not have records on who authored the memo, any requestor for the memo, or formal request that brought about the referenced memo. Furthermore, there is no record of a 'project master sheet,' 'review roaster file,' or ability to capture emails between critical areas staff for the 15 days prior to and after the memo's date associated with this topic."
The county also stated:
"The memo was the result of ongoing discussions between varied PDS staff, employed by the County at that time, to document their generally agreed upon position and intended to better assure consistency in permitting at that prior time. We have no record of the date(s)/time(s) that staff met to discuss the creation of the memo, who all were involved in those discussions, nor who received copies of the memo once created."
The county simultaneously claims the memo reflects the collectively agreed position of varied staff — formal enough to put on the Director's letterhead — and that no record exists of who was in any discussion, who wrote it, or who received it. You cannot have collective staff consensus with zero documentation of any staff meeting. Meetings happen on calendars. Emails happen. The county is not saying records were lost. It says they do not exist.
The Timeline
April 7, 2022: Mahaffie lists 4470 Castlerock for $229,000
April 12, 2022: Buyer #1 enters Pending Feasibility
April 22, 2022 — 1:28 PM: Buyer #1 reverts to Active — walks after 10 days
April 22, 2022: Magic Memo appears in PDS files
April 26, 2022: Bulanovs enter Pending Feasibility
May 18, 2022: Bulanovs remove contingency — 22 days in feasibility
July 13, 2022: Bulanovs close at $229,000
Buyer #1 spent 10 days and walked. The Bulanovs spent 22 days and stayed. The only documented event between those two feasibility periods is the appearance of a memo establishing the property's wetlands were already mitigated.
What the Investigation Did With This
Neither the Haggard report (July 2, 2024) nor the supplemental report (August 23, 2024) references this memorandum. It does not appear in either document.
Haggard interviewed the Director whose name is on the letterhead. She interviewed two supervisors from the same department. She interviewed Mahaffie twice. None of them mentioned it. Haggard concluded Nathan Goldschmidt made a legally questionable error — without ever finding the written departmental guidance that made Nathan Goldschmidt's determination defensible. Every PDS witness who sat across from her and allowed that conclusion to stand while knowing the memo existed chose silence.
Section 6: The Investigation
Stenography Presented as Findings
On May 9, 2024, attorney James Grifo submitted a 120-page complaint to County Executive Satpal Sidhu. The county retained Summit Law Group (Kristin Anger) to oversee an investigation by Haggard & Ganson LLP (Kathleen Haggard). On July 2, 2024, Haggard concluded: "A preponderance of the evidence does not support the allegation that Matthew Mahaffie inappropriately used his position."
The Brissenden Problem: One Word That Buried the Conflict
On page 2 of her July 2, 2024 report, Haggard wrote: “Tom Brissenden, a former natural resources planner for the county, is a staff ecologist at Skagit Wetlands.”
Every material fact in that sentence is wrong or misleading. Skagit Wetlands’ own qualifications document — Mahaffie’s company’s own marketing materials — establishes the following timeline:
Brissenden joined Whatcom County PDS as a Natural Resources Planner in 2016.
In 2019 — while still a sitting PDS Natural Resources Planner — Brissenden began working for Skagit Wetlands, Mahaffie’s private consulting company, as a staff ecologist. He held both positions simultaneously.
On June 24, 2021, Brissenden — in his capacity as a sitting Whatcom County Natural Resources Planner, while simultaneously employed by Mahaffie’s private company — signed the county approval memo for the wetland delineation of 8358 Blaine Road. The memo is addressed to Lara Kratzer, Mahaffie’s girlfriend and the property’s nominal owner. It was submitted June 3 and approved June 24: 21 days.
In March 2022, Brissenden transferred from PDS to Whatcom County Public Works. He did not leave county employment — he changed departments. He remains a Whatcom County employee.
When Haggard published her report on July 2, 2024, Brissenden was a current Whatcom County employee — not a former one. She described him as “former” in both her July 2 report and her August 23 supplemental report. She never corrected it.
The significance of this mischaracterization cannot be overstated. Haggard’s central exoneration finding is that Mahaffie “did not participate in the review of applications involving his properties.” That is technically true in the narrowest sense — Mahaffie himself did not sign the approval memo for 8358 Blaine Road. His employee did. The person who reviewed and approved the wetland delineation that enabled the sale of his girlfriend’s property for a $140,000 profit was simultaneously drawing a paycheck from Mahaffie’s private company.
Haggard also never interviewed Brissenden — the one person who could answer whether Mahaffie directed, discussed, or was aware of his review of the Kratzer property. He works in Public Works. He was available. She described him as a former employee and rendered him irrelevant to her investigation. The word “former” did the work that the investigation was designed to do.
Critical Witnesses Never Interviewed
Rob Merhaut — the real estate agent who represented both sides on the Blaine Road transactions. Haggard never asked what he disclosed to Beckwith, what Mahaffie told him about his role at the county, or how the dual agency arrangements were structured.
Rodney Helgeson — the dual-agent on the Castlerock purchase. He had direct knowledge of what Mahaffie disclosed, how the Sold-Unlisted transaction was structured, and what Mahaffie told him about the wetland status at the time of purchase — information that directly contradicts Mahaffie's claim that he did not know the wetlands were mitigated when he bought.
Lara Kratzer — nominal purchaser of 8358 Blaine Road, Mahaffie's live-in girlfriend. Who provided her funds? What was her understanding of the transaction? What communications existed between her and Mahaffie about the county permitting process he was running from her property?
Miguelina Beckwith — the seller who netted nothing on 8366 Blaine Road and zero cash on 8358. What was she told? What did she understand about who was buying her properties?
Amy Dearborn — the county staff member Mahaffie instructed his listing agent to direct buyers to for confirmation of the wetland status. She knew the mitigation position. When did she and Mahaffie discuss it?
What Was Accepted Without Verification
Mahaffie's claim he paid back taxes: Accepted without requesting the settlement statement. The seller's own tax records contradict it.
Mahaffie's claim of ignorance about wetland status at purchase: Accepted despite his listing agent marketing the opposite position months later, in instructions that came directly from Mahaffie.
Mahaffie's claim the Castlerock deal was arms-length: Accepted without interviewing the dual agent who represented both sides.
Mahaffie's claim the Blaine Road deals were arms-length: Accepted without interviewing Merhaut, without examining what Mahaffie disclosed to the agent about his regulatory role, and without considering what informed consent means when one party is a wetland regulator buying from a seller who can't sell because she's afraid of wetland complications.
Mahaffie's claim he never saw the 2023 NOAR: Accepted even though Nathan Goldschmidt told Haggard the opposite — and Haggard said she believed Nathan Goldschmidt.
What Haggard Admitted
Despite the conclusion of no wrongdoing, Haggard acknowledged in pages 8-9 of her report that Nathan Goldschmidt's 2023 determination was "legally questionable" under Alliance Investment Group v. City of Ellensburg, 189 Wn. App. 763 (2015). She admitted the permit may have been legally wrong. She recommended no action. She never found the April 22, 2022 memorandum that established the opposite legal position as written departmental policy.
Section 7: The Institutional Response
Dismissal, Then Threat
On August 30, 2024 — the same date AJ Bredberg submitted detailed additional evidence — Whatcom County Prosecuting Attorney Eric Richey wrote to attorney James Grifo:
"I hope that they are able to provide some reassurance to your clients that any appearance of inappropriate action was just an appearance."
Richey dismissed 120 pages of documented complaints without independent review. His office had previously been retained to defend county employees — including in RICO litigation involving Mahaffie — at taxpayer expense with County Council approval.
On October 23, 2024, Planning Director Mark Personius sent a letter threatening legal action against developer Dwayne Engelsman, who had informed the owner of Royal Emerald Motors that the mitigation arrangement was "a sham." Personius called this description a "reckless use" of the phrase "County corruption."
Copied on that letter: the Whatcom County Prosecuting Attorney's Office. Matthew Mahaffie. And the owner of Royal Emerald Motors.
The Prosecuting Attorney's Office received a copy of this letter. The office took no action to protect Engelsman's right to share public records and factual information. The office did not advise Personius that threatening a citizen for sharing factual information raises First Amendment concerns. The office monitored.
Section 8: The Lawsuit
On June 12, 2026, the Dierdorff family filed suit in Whatcom County Superior Court: Dierdorff v. Mahaffie et al., Case No. 2620124737, naming Matthew Mahaffie and Whatcom County as defendants.
The verified complaint alleges in paragraph 24 that the April 22, 2022 memorandum "confirmed that there were no wetlands or wetland buffers encumbering the Property because all wetland mitigation had already occurred as part of the plat approval process" — and that "there had been and there were no wetland-related issues to concern or dissuade prospective buyers."
The complaint alleges in paragraph 16 that Mahaffie "knew, or should have known" his 2017 NOAR was false, "given his expertise, access to records and information, and his role in processing and reviewing permits concerning other lots in the subdivision."
Discovery is expected to produce communications around the creation of the April 22, 2022 memorandum, Mahaffie’s seller disclosure forms for both the 2020 purchase and 2022 sale, and internal communications between the Prosecuting Attorney’s office and county officials regarding the investigation.
The Continuing Fraud Theory and the Statute of Limitations
The defense will argue that the original wrong — Mahaffie’s 2017 NOAR — is outside Washington’s three-year fraud statute of limitations. The plaintiffs have framed the lawsuit to defeat that defense by pleading not an isolated transaction but a continuing fraud, with each act of active institutional concealment constituting a new wrongful act that tolls and refreshes the limitations clock.
Under Washington’s fraudulent concealment doctrine, the statute of limitations does not begin to run until the plaintiff discovered or reasonably should have discovered the fraud. Active concealment — not passive non-disclosure — tolls the clock. The conduct documented in this investigation is not passive. It is a documented, multi-actor, institutional campaign of active concealment that continued well beyond the original transactions.
The concealment timeline is documented and dated:
2017–2020 — The original fraud. The false NOAR, the suppression of the Brady Mason contract, the off-market purchase through a shell company (Dead Goat) using a nominee purchaser (Kratzer). The Dierdorffs could not have discovered Mahaffie was the buyer — his identity was concealed by the LLC structure and the off-market transaction.
April 22, 2022 — The Magic Memo. An unsigned departmental memorandum appears in PDS files with no author, no requester, no distribution record. It creates official cover for the determination that unlocks the property’s value while ensuring no paper trail connects that cover to Mahaffie’s sale. The PRR response confirming nobody knows who created or received it is the county’s own admission that the concealment was structural.
July–August 2024 — The sham investigation. An investigation specifically structured to avoid finding material evidence: the Magic Memo never surfaced, Brissenden’s dual employment was mischaracterized, the financial records were never examined, the real estate agents were never interviewed, and the contradictory testimony was rationalized without resolution. Haggard’s false characterization of Brissenden as a “former” employee concealed the central conflict from the county, from the victims, and from the public.
August 30, 2024 — The Richey letter. Active reassurance to the victims’ attorney that documented concerns were merely “an appearance,” designed to discourage further inquiry and close the matter.
October 23, 2024 — The Personius threat letter. Active suppression of a witness who had shared factual information with affected parties. The threat was copied to the Prosecuting Attorney’s office, which took no action to protect the witness or correct the conduct.
Ongoing — Uncorrected false statements. The false characterization of Brissenden as a “former” employee has never been corrected. The Magic Memo has never been publicly disclosed or addressed. The investigation’s findings continue to be cited by county officials as justification for their conduct. Each day the false record stands uncorrected is a continuation of the concealment.
The last documented act of active concealment is October 2024 at the earliest, with ongoing concealment continuing to the present. Under the fraudulent concealment doctrine, the three-year limitations clock runs from last concealment — not from the original wrong. The lawsuit filed June 12, 2026 falls well within that window.
Every document in this investigation — every dated act of concealment, every false statement, every suppressed witness, every unexamined record — is also evidence in the continuing fraud timeline. The reporting and the litigation are parallel records of the same course of conduct.
Section 9: Questions for Comment
Responses should be directed to Brian Gass, Editor-in-Chief, Real Issues Podcast, at brian@realissuespodcast.org, no later than seven days from the date of this letter's transmission.
For Kathleen Haggard / Haggard & Ganson LLP
Did you review the PDS permit file for 4470 Castlerock Drive? If so, did you encounter the April 22, 2022 memorandum? If you were aware of it, why does neither report reference it?
You concluded Nathan Goldschmidt's determination was legally questionable. The county's PRR response confirms the memo represents the department's generally agreed upon position. How do you reconcile those conclusions?
You stated you believed Nathan Goldschmidt was telling the truth about consulting with Mahaffie. If Nathan Goldschmidt was truthful, Mahaffie's claim that he had never seen the 2023 NOAR was false. Why did your report make no credibility finding?
You accepted Mahaffie's claim he paid the back taxes on the Blaine Road properties. Did you request settlement statements? If not, why not? If so, what did they show?
You described both the Castlerock and Blaine Road transactions as arms-length. You did not interview Rodney Helgeson, Rob Merhaut, Lara Kratzer, or Miguelina Beckwith. On what basis did you conclude these were arms-length transactions?
Mahaffie used his county employer's mailing address and his personal email to coordinate permits for properties owned by his girlfriend. He offered to route permitting "through Phil" in his own department. What was your assessment of these facts?
For Kristin Anger / Summit Law Group
As supervising attorney, did you review the PDS permit file for 4470 Castlerock Drive? Were you aware of the April 22, 2022 memorandum?
What steps did you take to verify the completeness of the investigation before transmitting its findings to the county and to the victims' attorney?
The investigation described both transactions as arms-length without interviewing either real estate agent. What review did you conduct of that conclusion?

Section 10: The Parties
A quick-reference guide to the individuals and entities named in this report, organized by their institutional role.
Subject of the Investigation
Matthew Mahaffie — Natural Resources Planner, Whatcom County Planning and Development Services (PDS). Subject of the conduct described throughout this report.
Whatcom County Planning and Development Services (PDS)
Mark Personius, AICP — Director of Planning and Development Services. The April 22, 2022 memorandum that established the "no further mitigation" position appeared on his letterhead. He authored the October 23, 2024 letter threatening legal action against developer Dwayne Engelsman for sharing factual information with the owner of Royal Emerald Motors.
Tom Brissenden — Natural Resources Planner. Joined PDS in 2016. By 2019, he was simultaneously employed by Mahaffie's private consulting company Skagit Wetlands as a staff ecologist. On June 24, 2021, while a sitting Whatcom County PDS employee and a paid contractor for Mahaffie's company, Brissenden signed the county approval memo for the wetland delineation of 8358 Blaine Road — Mahaffie's girlfriend's property. He transferred to Whatcom County Public Works in March 2022. He remains a Whatcom County employee. The Haggard investigation never interviewed him and mischaracterized him as a "former" employee.
Joshua Fleischmann — Natural Resources Staff. Conducted the site inspection at 4348 Castlerock Drive (Bhullar property) on July 18, 2018 and found no critical-area impacts requiring mitigation. Same subdivision, same plat, same underlying 2002 mitigation, one year after Mahaffie's opposite determination on the neighboring 4470 Castlerock (Dierdorff).
Amy Dearborn — County staff member. In April 2022, Mahaffie instructed his listing agent to direct prospective buyers of 4470 Castlerock to her for confirmation that wetland mitigation had been satisfied by the plat. She knew the position the listing was selling.
Nathan Goldschmidt — Permit reviewer. Approved the June 2023 Bulanov building permit on 4470 Castlerock with the determination that "any potential impacts to wetlands and wetland buffers were previously mitigated for in the approval of the platted development" — the opposite position Mahaffie communicated to the Dierdorffs in 2017.
Whatcom County Prosecuting Attorney's Office
Eric Richey — Whatcom County Prosecuting Attorney. On August 30, 2024 — the same date attorney AJ Bredberg submitted detailed additional evidence — Richey wrote attorney James Grifo: "I hope that they are able to provide some reassurance to your clients that any appearance of inappropriate action was just an appearance." His office had previously been retained to defend Whatcom County employees, including Mahaffie, in RICO litigation at taxpayer expense with County Council approval.
George Roche — Deputy Prosecuting Attorney. CC'd on the October 23, 2024 Personius letter threatening legal action against Dwayne Engelsman. His office took no action to protect the citizen or to advise the Director that threatening someone for sharing factual information raises First Amendment concerns.
Kellen Kooistra — Deputy Prosecuting Attorney. CC'd on the October 23, 2024 Personius threat letter. His office took no action to protect Engelsman or correct the conduct.
Christopher Quinn — Chief Civil Deputy. Identified on the August 30, 2024 Richey letterhead. Civil-side counsel during the period the threat letter was monitored and not acted upon.
Laura Singletary — Administrative Manager. Identified on the August 30, 2024 Richey letterhead.
Whatcom County Council
The seven-member Whatcom County Council authorized the expenditure of taxpayer funds to defend Mahaffie in RICO litigation. None of the current councilmembers has publicly addressed the conduct documented in this report.
- Kaylee Galloway — Chair
- Elizabeth Boyle — District 2
- Jessica Rienstra — District 3
- Mark Stremler — District 4
- Ben Elenbaas — District 5
- Barry Buchanan — At-Large Rep A
- Jon Scanlon — At-Large Rep B
Whatcom County Executive
Satpal Sidhu — County Executive. Received the May 9, 2024 complaint from attorney James Grifo. Retained Summit Law Group to oversee an investigation by Haggard & Ganson LLP.
Outside Investigators
Kathleen Haggard — Partner, Haggard & Ganson LLP. Concluded on July 2, 2024 that "a preponderance of the evidence does not support" the allegations against Mahaffie. Did not interview Brissenden, Helgeson, Merhaut, Kratzer, or Beckwith. Did not request settlement statements. Did not identify the April 22, 2022 memorandum. Described Brissenden as a "former" Whatcom County employee in both the July 2 report and the August 23 supplemental report; never corrected the mischaracterization. Acknowledged on pages 8–9 of her report that the 2023 Bulanov determination was "legally questionable" but recommended no action.
Kristin Anger — Partner, Summit Law Group. Supervising attorney engaged by the County Executive to oversee the investigation.
August 2026 Primary Candidates for Prosecuting Attorney
Erik Sigmar — Currently Chief Criminal Deputy in the Prosecuting Attorney's Office throughout the period described in this report. Endorsed by Richey as his successor.
Dona Bracke — Candidate running on a platform of change. Attorney with personal experience of institutional retaliation for refusing to participate in misconduct.
Mahaffie's Companies and Nominees
Dead Goat Properties LLC — Formed February 7, 2019. Governor: Matthew Mahaffie. Registered agent: Reta Stephenson (Mahaffie's mother) at 909 Alderwood Lane, Sedro Woolley. Formed four days before the Skagit County purchase at 22788 Grip Road and 60 days before the Blaine Road purchases.
Skagit Wetlands — Matthew Mahaffie's private wetland-consulting company. Employed Tom Brissenden as a staff ecologist from 2019 onward while Brissenden was simultaneously a sitting Whatcom County PDS employee.
Reta Stephenson — Mahaffie's mother. Registered agent for Dead Goat Properties LLC at her home address in Sedro Woolley.
Lara Kratzer — Mahaffie's live-in girlfriend. Nominal purchaser of 8358 Blaine Road in April 2019. Shared a mailing address with Mahaffie. The county approval memo for her property — signed by Brissenden, then on Mahaffie's payroll — was addressed to her.
Royal Emerald Motors — Business under PDS regulation. Mahaffie signed an agent authorization in 2022 allowing the business to use 8366 Blaine Road as an offsite wetland mitigation site. Mitigation credits in the area are valued at approximately $350,000 per acre; at 7.5 acres, the potential mitigation-credit value is in the range of $2.6 million.
Plaintiffs, Complainants, and Witnesses
The Dierdorff family — Original owners of 4470 Castlerock Drive (purchased 2007 for $150,000). Subjected to an 18-month permitting denial by Mahaffie in 2017–2018. Sold the property to Dead Goat Properties for $80,000 in October 2020. Total documented loss: approximately $120,750. Filed Dierdorff v. Mahaffie et al., Case No. 2620124737, in Whatcom County Superior Court on June 12, 2026.
Bill Dierdorff — The son who took over the matter after his father could no longer continue. Named applicant on the July 28, 2017 NOAR for 4470 Castlerock and the contemporary representative of the Dierdorff family in this record.
Brady Mason — Builder and partner of the Dierdorffs in 2019. Contracted to purchase 4470 Castlerock from the Dierdorffs at $150,000 in August 2019, intending to develop the lot. Hired AJ Bredberg to investigate the wetland status. Submitted a mitigation plan directly to Mahaffie in October 2019. Then abandoned the contract. No public explanation has ever been provided.
James Grifo — Attorney representing the Dierdorffs and other affected parties. Submitted a 120-page complaint to County Executive Sidhu on May 9, 2024. Recipient of Richey's August 30, 2024 "appearance" letter.
AJ Bredberg — Independent wetland consultant. Operates his own wetlands-expertise company. Investigated the 4470 Castlerock property on behalf of Brady Mason. Submitted detailed additional evidence to the county investigator on August 30, 2024 — the same date Richey wrote to dismiss the matter.
Miguelina Beckwith — Elderly widow. Owner of two adjacent 7-acre parcels at 8358 and 8366 Blaine Road. Sold both in April 2019 to Mahaffie's girlfriend and Dead Goat Properties respectively. The sale triggered removal of agricultural tax designations. Beckwith herself paid the back taxes — more than her $10,000 in gross proceeds from 8366 — meaning she netted negative cash on the transactions. The Haggard investigation never interviewed her.
Dwayne Engelsman — Developer. Informed the owner of Royal Emerald Motors that the mitigation arrangement at 8366 Blaine Road was "a sham." Received an October 23, 2024 letter from Director Personius threatening legal action over his "reckless use" of the phrase "County corruption." The threat letter was copied to the Prosecuting Attorney's office.
Real Estate Agents Involved in the Transactions
Rodney Helgeson — Real estate agent. Represented both seller (Dierdorffs) and buyer (Dead Goat Properties / Mahaffie) in the October 2020 Castlerock transaction as a dual agent on a Sold-Unlisted listing that never reached the public market. The same agent acted as Mahaffie's listing agent when Mahaffie resold the property in April 2022 for $229,000 — directing potential buyers to county staff Amy Dearborn for confirmation of the wetland status Mahaffie himself had previously denied existed. Never interviewed by the Haggard investigation.
Rob Merhaut — Real estate agent. Began as Beckwith's listing agent on the Blaine Road properties, with a fiduciary duty to obtain her best price. Converted to dual agency representing both Beckwith and the buyers (Kratzer/Dead Goat/Mahaffie). Never interviewed by the Haggard investigation.
Outside Consultants
Northwest Wetlands Consulting LLC — Private wetland-delineation firm. Performed the Critical Areas Assessment field demarcation for 8358 Blaine Road (Lara Kratzer's parcel) summarized in the May 29, 2021 report. Whatcom County PDS staff (Tom Brissenden) concurred with the firm's findings in the June 24, 2021 approval memorandum.
Katrina Jackson — Wetland delineator at Northwest Wetlands Consulting LLC who performed the on-site work for 8358 Blaine Road. Her determination was the one County PDS adopted in the Brissenden Approval memo.
The Original Plat
The Greens at Loomis Trail — Residential subdivision in Blaine, Washington, platted under permit LSS1994-00004 with supplemental mitigation permit MIT2003-00021. The original developer conducted extensive wetland mitigation as part of the platting process — completed, monitored, and approved by Whatcom County. The wetland obligations on individual lots were discharged at the plat level. The contrast between Mahaffie's 2017 determination on the Dierdorff lot and the routine no-mitigation findings on adjacent and similar lots before and after is documented in the county's own permit files.
