From the Residents of Rancho Madrone

October 28, 2026

VIA ELECTRONIC MAIL ONLY

Dear Supervisor Hermosillo and Director Hoevertsz:

We write jointly as residents of fourteen households on all four streets of the Rancho Madrone subdivision. We were sorry to learn of the Supervisor’s family emergency, and we thank her for her October 27 email, for adding Glenwood Drive to her District 1 road improvement list, and for inviting residents to Thursday’s Municipal Advisory Council meeting.

We also write to correct the record on two points, and to ask three questions.

I. THIS IS A NEIGHBORHOOD EFFORT

The Supervisor’s email states that the County will not allow its process to be circumvented “because one neighborhood believes it should be paved ahead of others in order to close a real estate transaction.”

That is not why we are writing. Residents have sought repair of these streets for decades. The fourteen households signing this letter, listed with their addresses at the end, live on all four streets.

THE RECORD DOES NOT DEPEND ON ANY ONE RESIDENTOn October 12, 2026, the County’s own staff rated Glenwood Drive “Very Poor,” the lowest category on the County’s scale, and wrote “This is a hazard and action will be take.” Those facts are the same for every household on these streets, whatever any one resident’s personal circumstances. Speculation about one resident’s motives does not change the condition of the road or the County’s knowledge of it.

II. ACCURACY

The Supervisor writes that “many of the daily AI-generated emails … contain inaccurate assumptions about County procedures, timelines, and administrative obligations.”

How a letter is drafted has no bearing on whether it is accurate. The facts in the record come from the County’s own documents: SPI’s emails of October 12, the County’s published pavement scale, the 2026–27 Modified List of Recommended Roads, and MTC’s published pavement data. Where the record set response dates, it said plainly that only the Public Records Act deadline is set by statute.

If any statement in the prior notices is inaccurate, we ask that the County identify it, so that it can be corrected on the record. We have no interest in repeating an error.

III. WE AGREE ON OBJECTIVE CRITERIA

We agree that road repair should be decided by “objective criteria, including pavement conditions, traffic volumes, safety considerations, geographic equity, available funding, and professional engineering assessments.” That is why we ask how those criteria were applied here:

• Glenwood Drive is rated “Very Poor,” PCI 0–24 on the County’s scale, with documented safety, drainage, and accessibility concerns.
• The 2026–27 list funds $3.3 million for Napa Road, rated “Very Good,” and two District 1 roads rated “Very Poor.” None of the four Rancho Madrone streets appears.

IV. THREE QUESTIONS

1. The District 1 road improvement list. What is this list, when was Glenwood Drive added, and are Oakwood, Brookview, and Maplewood Drives on it?
2. The October 12 commitments. SPI wrote that it would add the paving request to the Pavement Preservation Program list and “mitigate any immediate hazards,” and that “This is a hazard and action will be take.” What has been done on each?
3. Accuracy. Which statements in the prior notices does the County consider inaccurate?

We understand the Supervisor’s calendar is scheduled about six weeks in advance. Residents are requesting a meeting through her scheduler, and we look forward to the County’s Public Records Act determination on Request No. 26-871, due November 2, 2026.

V. THURSDAY’S MEETING

Residents plan to attend the joint Municipal Advisory Council meeting on Thursday, October 29, 2026, at 5:30 p.m. at the Lomita Service Center, 19080 Lomita Avenue, Sonoma, and to share these concerns during the discussion of Sonoma Valley infrastructure.

Director Hoevertsz has thanked residents several times “for remaining engaged.” The Supervisor’s October 27 email states that it will be her final personal response. We will remain engaged, through the channels the Supervisor identified: her scheduler, Thursday’s meeting, and the Public Records Act process, until these streets are safe and repaired.

Respectfully,

The Residents of Rancho Madrone
