Black Diamond Proposition 1 2026: What Homeowners and Buyers Should Know

Election status: Unofficial. King County Elections requires a simple majority for the measure and plans to certify the August primary on August 18, 2026. The latest official vote totals should be inserted from the King County results page before publication.

Black Diamond Proposition 1 asks whether the city should become part of the Puget Sound Regional Fire Authority for fire protection and emergency medical services.

Annexation would make Black Diamond a member jurisdiction of the regional fire authority rather than continuing to rely only on a service contract. If the measure is approved and certified, Puget Sound Fire would begin serving the city on January 1, 2028.

The measure involves more than changing the name on a fire engine. It could change how fire and emergency medical services are funded, how the city is represented in regional decisions, and how homeowners evaluate future property carrying costs.

Current election status

King County’s official results page confirms the simple-majority requirement. The accessible page text did not display the current vote totals during this review, so this article should not state that the measure has passed or failed until those totals are verified directly.

Proposition 1 facts

The City of Black Diamond describes the measure as a proposal to move from its current contracted service arrangement to membership in Puget Sound Fire. The City says the proposed model would staff both Black Diamond stations with three firefighters each and provide the city with two representatives on the regional authority’s governing body.

Key takeaways

• Black Diamond currently receives fire and emergency medical service through a contract with Mountain View Fire & Rescue.
• That contract expires December 31, 2027.
• If Proposition 1 is approved and certified, Puget Sound Fire would begin service January 1, 2028.
• The City says the proposed arrangement would staff two Black Diamond stations with three firefighters each.
• Puget Sound Fire uses a property-tax levy and a Fire Benefit Charge.
• A Fire Benefit Charge is not calculated the same way as a standard property tax.
• The City says no annexation-related charges would appear in 2026 or 2027.
• No universal homeowner cost applies to every property.
• Black Diamond would receive two representatives on the governing body, according to the City.
• The result remains unofficial until certification.
• Black Diamond Proposition 1 and Fire District 43 Proposition 1 are separate measures.

What is Black Diamond Proposition 1?

Black Diamond Proposition 1 asks whether the City of Black Diamond should annex into the Puget Sound Regional Fire Authority.

The official ballot language asks whether the city should become part of the authority so Puget Sound Fire can provide fire and emergency medical services beginning January 1, 2028.

Annexation is different from renewing a short-term service contract.

Under annexation:

• Black Diamond would become part of the regional fire authority.
• Puget Sound Fire would become responsible for fire and EMS service.
• The regional authority’s funding system would apply.
• Black Diamond would participate in regional governance.
• The arrangement would begin after the current contract ends, not immediately after the election.

The Black Diamond City Council placed the measure on the August 4 ballot through Resolution No. 26-1739. A separate resolution approved the potential annexation agreement.

Who currently provides fire and emergency medical service?

Black Diamond currently receives fire and EMS through a contract with Mountain View Fire & Rescue.

The City says that contract expires at the end of 2027. Current service therefore continues during 2026 and 2027, regardless of the initial election-night count.

The proposed annexation is intended to determine the service structure after the contract expires.

That timing matters for homeowners and buyers because:

• There is no immediate provider change in 2026.
• There is no proposed transition before January 1, 2028.
• Election results must still be certified.
• The City and regional authority would need to complete the implementation process.
• Future funding would begin under the regional model rather than through the City’s General Fund.

What would change if annexation is approved?

Puget Sound Fire would assume responsibility for Black Diamond fire and emergency medical services beginning January 1, 2028.

The City says the proposed arrangement would include:

• Two staffed Black Diamond fire stations
• Three firefighters assigned to each station
• Six firefighters on duty around the clock
• Access to Puget Sound Fire’s broader regional system
• Dedicated regional funding
• Two Black Diamond representatives on the governing body

The staffing information should be understood as the City’s description of the proposed agreement. It should not be converted into an unsupported promise about exact response times, insurance premiums, or outcomes for every emergency.

What would not change immediately?

If the measure is approved:

• Mountain View Fire & Rescue would continue providing contracted service through 2027.
• Puget Sound Fire would not begin service until January 1, 2028.
• New annexation-related property charges would not appear in 2026 or 2027.
• A preliminary election count would not immediately change a homeowner’s tax bill.
• Existing real estate transactions would still need to use current tax and service information until the transition occurs.

How would Puget Sound Fire be funded?

Puget Sound Fire uses a two-part funding system:

1. A property-tax levy
2. A Fire Benefit Charge

The City says fire and EMS services would be funded directly by the regional authority rather than through Black Diamond’s General Fund if annexation is approved.

Property-tax levy

The property-tax levy is tied to assessed property value and the authority’s adopted levy rate.

A homeowner’s share would depend on factors such as:

• The property’s assessed value
• The levy rate in effect
• Applicable exemptions
• Changes in assessed value
• Other taxing-district levies

This would be one part of the total property-tax statement, not the entire tax bill.

Fire Benefit Charge

A Fire Benefit Charge is not calculated the same way as a standard property tax.

The City says the charge applies to property improvements rather than land and may consider:

• Building size
• Property use
• Fire risk
• The benefit the structure receives from fire protection
• Applicable formulas, discounts, and exemptions

The City also states that the charge is not based on the number of emergency calls to a property.

Fire benefit charges are generally structured as fees tied to the measurable benefit a property receives from fire protection rather than as conventional property taxes.

How can a homeowner estimate the cost?

There is no universal amount that applies to every Black Diamond homeowner.

A property-specific estimate may require:

• Current assessed value
• Building size
• Property use
• Fire-risk classification
• Current levy rate
• The Fire Benefit Charge formula
• Monitored alarm discounts
• Senior, disability, or veteran exemptions
• Other adjustments

Campaign examples should not be presented as official property bills. An amount quoted in a voter statement may illustrate one argument, but it does not establish what a particular homeowner would pay.

When would new charges begin?

The City says property owners would not see new annexation-related fire charges in 2026 or 2027.

The proposed regional funding model would begin in 2028 if the annexation is approved and implemented.

That means a buyer purchasing in late 2026 or during 2027 should review:

• The current property-tax statement
• The possible 2028 funding change
• The expected closing and ownership timeline
• Future escrow estimates
• Official Puget Sound Fire calculation tools when available

What exemptions or discounts may apply?

The City says qualifying seniors, people with disabilities, and disabled veterans may be eligible for property-tax relief through King County.

It also says homes and businesses with monitored alarm systems may qualify for a Fire Benefit Charge discount.

Eligibility should be confirmed with the responsible agency. A buyer should not assume an exemption or discount automatically transfers from one owner to another.

How would Black Diamond be represented?

The City says Black Diamond would receive two representatives on the Puget Sound Fire governing body, the same number described for each partner city.

The governing body is responsible for regional decisions involving:

• Budgets
• Policies
• Service planning
• Funding
• Capital needs
• Regional operations

The City’s public summary confirms the number of representatives but does not fully explain the selection process in the accessible text.

Before publication, the pre-annexation agreement should be checked to confirm:

• Whether the representatives are appointed or elected
• Who chooses them
• The length of their terms
• When representation begins
• Whether the arrangement changes after a transition period

The important real estate point is that annexation would not mean Black Diamond has no local voice. It would change the form of that representation.

What happens if Proposition 1 is not approved?

Black Diamond would remain responsible for arranging fire and EMS service after the current contract expires.

The City says its existing revenue structure would not support continuing the current arrangement without additional revenue, reductions to other General Fund services, or another service solution.

Possible next steps could include:

• Negotiating another service contract
• Considering another annexation proposal
• Seeking additional City revenue
• Revising General Fund spending
• Exploring another service model

None of those outcomes is automatic.

The result of the election would determine whether the proposed Puget Sound Fire annexation moves forward, not every later budget or service decision.

Has Black Diamond Proposition 1 passed?

The result should not be described as final until King County Elections certifies the election on August 18, 2026.

Use the following update box when publishing:

Latest official count: [Insert Yes and No totals]
Last updated: [Insert King County Elections timestamp]
Current status: Unofficial
Certification date: August 18, 2026

When the measure is leading, say:

Proposition 1 is leading in the current unofficial count.

When the measure is trailing, say:

Proposition 1 is trailing in the current unofficial count.

Avoid saying “passed” or “failed” before certification unless King County Elections formally identifies the result under its procedures.

King County also lists the Black Diamond measure separately from Fire District 43 Proposition 1, even though both concern Puget Sound Fire.

What should Black Diamond homeowners consider?

Homeowners should treat the measure as one part of their long-term ownership-cost and service picture.

Review:

• The certified election result
• The January 1, 2028 service timeline
• The property’s current tax statement
• The future levy rate
• The Fire Benefit Charge calculation
• Possible exemptions or discounts
• Homeowners-insurance quotes
• HOA dues
• Water and sewer costs
• Other City taxes and fees
• Planned development and infrastructure

The measure does not provide enough information to predict that home values or insurance premiums will rise or fall.

Black Diamond is also managing long-term housing and infrastructure growth. Buyers and owners can review how Black Diamond’s master-planned communities are being built in phases and the proposed Miner’s Ridge expansion at Ten Trails when evaluating the broader service picture.

What should buyers verify before purchasing?

Buyers should evaluate Proposition 1 as one part of the full cost and service profile of a Black Diamond home.

Buyer checklist

1. Confirm the certified election result.
2. Review the property’s current King County tax statement.
3. Ask how the Fire Benefit Charge may apply to the structure.
4. Confirm whether any exemptions or discounts are relevant.
5. Obtain a property-specific homeowners-insurance quote.
6. Review HOA dues and included services.
7. Verify water, sewer, septic, and other utility arrangements.
8. Review nearby housing and infrastructure plans.
9. Compare Ten Trails with established Black Diamond neighborhoods.
10. Avoid assuming that one campaign cost example applies to the property.
11. Ask how the possible 2028 charges may affect escrow or monthly budgeting.
12. Verify all current figures again before closing.

For local neighborhood context, review what buyers should know about Black Diamond beyond Ten Trails.

What should sellers say about Proposition 1?

Sellers should describe the measure, result, and timeline accurately without promising a specific cost or service outcome.

Avoid saying:

• The measure passed before certification.
• Every homeowner will pay the same amount.
• Response times are guaranteed to improve.
• Insurance premiums will fall.
• The measure has no effect on ownership costs.
• Black Diamond Proposition 1 is the same as Fire District 43 Proposition 1.

A safer description is:

Black Diamond voters considered annexation into the Puget Sound Regional Fire Authority. Buyers should verify the certified election result, the proposed 2028 funding structure, and property-specific costs through official sources.

Sellers should also avoid including an estimated future levy or Fire Benefit Charge in marketing unless the figure comes from an official property-specific calculation.

How is this different from Fire District 43 Proposition 1?

Black Diamond Proposition 1 and Fire District 43 Proposition 1 are separate ballot measures involving different jurisdictions.

Both concern annexation into Puget Sound Fire, but one applies to the City of Black Diamond and the other applies to Fire District 43. King County lists them separately.

The distinction matters because:

• Different voters decide each measure.
• The jurisdictions have different boundaries.
• The service and funding transitions may differ.
• The effective timelines and property impacts should not be assumed to be identical.

The separate Fire District 43 Proposition 1 guide should be used only for properties inside that jurisdiction.

Expert insight: What this means locally

Black Diamond Proposition 1 is best understood as a long-term service, funding, and governance decision.

For homeowners, the practical question is how the proposed 2028 funding model may fit into annual carrying costs.

For buyers, fire service should be reviewed alongside:

• Property taxes
• Insurance
• HOA dues
• Water and sewer service
• Septic systems where applicable
• Commute
• Planned development
• Neighborhood location
• Long-term ownership plans

For sellers, the safest approach is to share verified facts without predicting response times, insurance savings, property values, or a universal homeowner cost.

A regional fire-authority decision can be relevant to a real estate purchase, but it should not be evaluated in isolation from the property itself.

Frequently asked questions

When would Puget Sound Fire begin serving Black Diamond?

If Proposition 1 is approved and implemented, Puget Sound Fire would begin providing service on January 1, 2028. Mountain View Fire & Rescue would continue under the existing contract through the end of 2027.

When would the first new fire-related charge appear?

The City says no new annexation-related charges would appear in 2026 or 2027. The proposed funding system would begin in 2028.

Is the Fire Benefit Charge based on land value?

The City says the charge applies to property improvements, not land, and may consider structure size, use, and fire risk.

Is the Fire Benefit Charge the same as a property tax?

No. Puget Sound Fire uses both a property-tax levy and a separate Fire Benefit Charge. They use different calculation methods.

Can a monitored fire alarm reduce the charge?

The City says homes and businesses with monitored alarm systems may qualify for a discount. The property owner should verify current eligibility and documentation requirements.

Would Ten Trails and older Black Diamond homes pay the same amount?

Not necessarily. The property-tax portion depends on assessed value, while the Fire Benefit Charge may consider the size, use, and fire risk of improvements. Different properties may receive different calculations.

Can a buyer estimate the Fire Benefit Charge before closing?

A buyer may be able to request an estimate using the current formula and the property’s structure details. The calculation should be confirmed through official sources before relying on it.

Who would select Black Diamond’s two representatives?

The City confirms that Black Diamond would have two representatives but the complete selection process should be verified in the pre-annexation agreement before publication.

Could annexation change homeowners-insurance costs?

Possibly, but no general outcome can be promised. Insurance pricing depends on the property, insurer, coverage, claims history, fire-protection information, construction, and underwriting rules. Buyers should obtain a property-specific quote.

What happens to the Mountain View Fire contract?

The City says the current contract expires December 31, 2027. If annexation is approved, Puget Sound Fire would begin service the following day.

When will the election result be certified?

King County Elections plans to certify the August primary on August 18, 2026.

Is Black Diamond Proposition 1 the same as Fire District 43 Proposition 1?

No. They are separate measures involving different jurisdictions, although both concern annexation into Puget Sound Fire.
