Larimer County advances draft addressing and road-naming resolution to improve emergency response and clarify appeals

Larimer County commissioners reviewed a draft update to the county’s addressing and road-naming resolution at a March 31, 2025, work session intended to shorten a 20-year-old document, standardize procedures and improve emergency-response reliability across unincorporated areas.

County staff said the update narrows terminology, adds standardized forms and templates and formalizes a public-safety review when property owners request exceptions to the rules. Greg Turnbull, Director of Innovations and Insights in the county’s information-technology department, said, “The goal with this resolution was to create something that we could we could launch from.”

The draft addresses three recurring problems staff and emergency responders described: duplicate or inconsistent road names, nonsequential or confusing address numbers, and a lack of standardized outreach and documentation when names or numbers change. Staff told the commissioners the prior resolution grew out of a 2000s rural-addressing project, became cumbersome and was inconsistently applied, and that the update is meant to be shorter but more comprehensive.

Key changes and procedures

- Coordinator role and standard forms: The county will formalize the addressing coordinator role and require a standardized online “request to deviate” form for any property owner who objects to an assigned address or road-name change. Staff said the form will require supporting documentation and a stated reason for the exception request.

- Agency review and public-safety input: The coordinator will invite affected emergency-response agencies — dispatch, EMS, law enforcement, fire and the county Office of Emergency Management — and partner agencies such as LITA to review deviation requests for public-safety impacts. Bill Resue, Larimer County Attorney, told commissioners the appeal hearing can be scheduled on any public agenda if it is noticed 24 hours in advance: “As long as it's noticed 24 hours in advance as a a public meeting, it can happen on any of your agendas.”

- Threshold for naming private drives: The draft aligns with partner guidance that the appearance of more than a single dwelling on a previously unnamed spur or private drive should prompt a naming or renaming review; staff described a working threshold of two properties as a trigger for evaluation.

- Road-name priority rules: When duplicate road names exist staff will prioritize which road keeps the name by recorded age and by minimizing impacts (for example, changing the name used by fewer property owners rather than a road affecting more addresses).

- Numbering rules: The update emphasizes sequential numbering, parity (odd/even) and minimizing number jumps that confuse responders and delivery services.

- Outreach and coordination with USPS and municipalities: Staff said the county will publish the new process on its addressing website, notify affected property owners in advance of any change and send a consolidated notification of new/changed addresses and road names to the U.S. Postal Service and municipal partners on the 15th of each month.

- Appeal process: Staff described a two-step process: an initial staff decision on a request to deviate (informed by agency review) and, if dissatisfied, an appeal to the Board of County Commissioners. Staff emphasized the appeal is intended to resemble land-use appeals and may be quasi-judicial in form; appeals should be submitted within 30 calendar days of the staff decision. Commissioners discussed the importance of clear criteria and limits on ex parte communications during such hearings.

Why it matters

County staff and several commissioners highlighted concrete examples where addressing issues delayed emergency response. Staff cited an incident in which an engine with water went the wrong direction while other units arrived lacking water supply, and repeated medical calls in Estes Park that routed crews to a different 160 Riverside Drive because of address duplication. Commissioners said such misroutes and delays have direct public-safety consequences, and that clearer rules and better outreach could reduce those risks.

Outstanding items and next steps

No formal action or vote was taken during the work session. Staff said they will finalize the draft resolution and the standard forms, post process and forms on the addressing website and return the resolution for formal consideration by the board. Commissioners asked staff to ensure the forms and appeal packet supply the specific, objective review criteria the board will use, and to clarify whether appeals should be heard in special meetings or on regular agendas. Staff said they will provide that information when the resolution returns to the board.

Implementation support and resources

Staff credited Christine Day and the addressing team with much of the operational work and noted ongoing coordination with LITA, municipal partners and the Postal Service. County staff said they will assist property owners through address transitions (for example, with pharmacies and postal issues) and will follow up if mailed medications or services fail to arrive after an address change.

No formal vote or ordinance adoption occurred at the March 31 session; commissioners directed staff to finalize materials and bring the proposed resolution back for formal consideration.
