Larimer County Rural Addressing Project

Road Renaming Project Pause

As of 3/22/2023, unless resident initiated, Larimer County's project to rename existing named roads in unincorporated Larimer County in alignment with the addressing resolution, is paused, with no immediate plans to resume.

Road Name Changes Completed: August 2022 - January 2023

1. When was the road renaming project paused?
  • On March 23, 2023, Larimer County initiated road renaming in unincorporated Larimer County was put on pause. At that time, all roads that were already in the process of being renamed were completed and finalized on May 15, 2023.
  • The decision to pause the road renaming was made by the current Board of County Commissioners.
2. What is the impact of the pause on neighborhoods that have already gone through the process?
  • All work done as part of the Addressing Project before the above dates will remain in effect.
3. We have not received anything from USPS regarding our address change. What information can you provide regarding this issue?
  • The Larimer County Addressing team has contacted the Denver USPS team regarding delays in updating their system with address changes. On June 14th, we received confirmation from the Denver USPS team that they will review all address changes provided by Larimer County to ensure they are entered into their system correctly. The Larimer County Addressing team will continue to monitor this situation.
4. The following link can be used to check for address updates

Larimer County is authorized and charged with assigning and changing road names and addresses as part of administering roads within Larimer County consistent with the:

Larimer County has initiated and is driving a project to identify duplicate, similar sounding, out-of-compliance street naming and unnamed private drives in Larimer County.  Affected areas will be worked on in phases, not all at once.

To make informed decisions regarding road naming and address changes, Larimer County is leveraging the experience and input of our partners:

  • Larimer Emergency Telephone Authority (LETA)
  • local Emergency Medical Services, Fire Protection Districts,
  • E911 Dispatchers, and
  • Municipalities.

I received a letter from Larimer County Addressing saying...

  • My road name needs to change OR
  • My private drive needs to be named

Now what?

  1. Each affected property owner will receive a letter requiring them to change their address.
    The letter will encourage neighbors to work together to identify a new name within 45 days of the date of the letter.  
  2. Please refer to the Street Inventory lookup web page and the rules governing street naming to assist in this process.
  3. Street name questions and requests can be sent to the Larimer County Addressing team at larimeraddressing@larimer.gov

What happens once a new road name has been chosen and approved?

Affected property owners will receive a Site Address Change Notification letter from Larimer County Addressing.

Simultaneously, address notifications changes are sent to:

  1. LETA (Larimer Emergency Telephone Authority / E911).
    LETA will incorporate the new addresses into their CAD system for E911 dispatchers throughout Larimer County.
  2. Larimer County Assessors Office, which updates the property records.
  3. USPS (United States Postal Service) Denver Office. 
    USPS will process the address changes into their system, and residents will receive a confirmation letter from USPS once the change has been completed.
*IMPORTANT: Be sure to avoid potential medication delivery disruption during these changes. If you have medication delivered to your residence, contact your provider as soon as possible, notify them of your address change and make other arrangements to receive your medication until you are confident all address changes have taken effect.

FAQs

  1. Why is it necessary to change my road name?

    Any private access driveway that provides access to more than one residence must become a named private access drive. There are situations when a person is either in distress, such as suffering from a heart attack or stroke while trying to call 911.  

    When only the street name is provided to 911, and there are two or more streets with the same or similar name, emergency services are not sure where to go. 

    We are reducing this risk by following the road naming standards set forth by the Larimer County Road Naming and Site Addressing Resolution and the LETA Street Naming and Addressing Standards Agreement.

  2. Why is this a problem now when duplicated road names have existed for decades?

    Larimer County adopted regulations in 2006 to eliminate confusion with road names, however recently addressing was moved to IT GIS which has allowed us to leverage GIS tools and data analysis capabilities to review Larimer County road and address data throughout Larimer County.  

  3. What happens after a road name is identified as needing to be changed?
    1. A list of duplicated street names is presented to the Emergency Response teams and E911 dispatch team for the area affected. A collaborative work session prioritizes duplicate street names based on areas of concern.
    2. The streets identified as the highest risk are assessed based on the following criteria.
      1. Streets that have the least amount of addresses affected will get changed.
      2. If there is a tie in the number of addresses, the street named most recently will change.
      3. This only applies to streets in unincorporated Larimer County. Roads with duplicated names within a municipality within the same emergency service area will be discussed. Municipalities determine how and when to change street names within their jurisdiction. To date we have worked together to reduce any conflicting names.
    3. A letter is sent notifying the property owners of the required name change. Residents whose addresses will change will be allowed to pick their street name within 45 days. If a majority of residents can not agree upon a street name, the county will choose the name.
  4. How do I pick a new street name?

    The Street Inventory System (SIS) contains the names of all streets in Larimer County and its municipalities. The purpose of this system is to provide a central location for all names, prevent duplicate street names in the future, and allow only approved suffixes. In addition you will also find the street naming standards.

    New road names must not sound alike or contain similar words to current ones to eliminate confusion. For example, Tranquil is already a road in Estes Park. Therefore, Tranquility couldn't be used. The same is true for Hideaway vs. Hide-A-Way or Starview vs. Star View. A caller to 911 won't be able to make verbal distinctions between these names.

    Other examples would be overused common nouns or adjectives; the road names of Hidden Cove, Hidden Pines, Hidden Valley, Hidden Canyon, Hidden Rock, etc., are already in use, so Hidden can't be used anymore.

    Common nouns can also cause confusion, such as Bear, since Black Bear, Brown Bear, Sleeping Bear, Little Bear, Big Bear, Yogi Bear, etc., are all currently in use. A 911 caller could easily tell a dispatcher they are located on "Hidden Something" or "Bear Something" when they are confused or distressed. These can be incredibly confusing for children or vacationers.

  5. Who will be responsible for changing the street signs and when will the signs be changed?

    LARIMER COUNTY STANDARD ROAD NAME SIGNS are required at all road intersections on private and public roads.  Larimer County will replace county street signs, the timing will be dependent on the weather and if a pole needs to be placed as well as the schedule and availability of the teams that will be replacing the signs.

    HOA custom signs will need to be replaced by the HOA, 

  6. Will my house number change?

    Larimer County prefers NOT to change house numbers. However, there are instances where changing the house numbers will be required; some examples we have seen are:

    • The current street has all odd house numbers on both sides of the street.
    • The current street has all even numbers on both sides of the street.
    • The current street has odd and even house numbers on the same side of the street.
    • The current street has numbers that are not in sequential order.
  7. When do I start notifying others my new address?

    Once a new road name has been assigned, Larimer County Addressing will send an official notice of change of address to affected residents. We also notify the Denver Colorado USPS (United States Postal Service), Larimer Emergency Telephone Authority (LETA E-911), and the Larimer County Assessor’s Office.

    Once the Denver USPS processes the address change and notifies the affected local post office, residents should receive a second official notification from their local US Post Office that the address change has been updated in their system. Larimer County recommends waiting 30 days after residents receive the notification from their local post office before starting any change of address notifications to businesses, friends, and family, the same as if you had moved.

    • Per the USPS: Please do not submit a USPS change of address to the USPS for any addresses that have been changed as part of the Larimer County Rural Addressing Project.
    • USPS will keep the old address on file for one year.  Mail utilizing the old address will still be delivered for up to 1 year.

  8. Who is responsible for all the steps after a road name is changed?

    Once a new road name has been assigned, Larimer County Addressing will send an official notice of change of address to affected residents. We also notify the Denver Colorado USPS (United States Postal Service), Larimer Emergency Telephone Authority (LETA E-911), and the Larimer County Assessor’s Office.

    Once the Denver USPS processes the address change and notifies the affected local post office, residents should receive a second official notification from their local US Post Office that the address change has been updated in their system. Larimer County recommends waiting 30 days after residents receive the notification from their local post office before starting any change of address notifications to businesses, friends, and family, the same as if you had moved.

    Notice!

    **It is strongly recommended that residents that receive medication by mail contact their Doctor to discuss alternative arrangements to receive that medication during this transition period.** 

  9. What is the process to for updating UPS, Fed EX, Google Maps, etc.?

    The information Larimer County has been provided is that once the Denver, Colorado USPS has updated the addresses, other businesses update their address databases from the USPS database. However, each company is on its own cycle for these updates, and the county cannot determine the timing of these updates.

    Notice!

    **It is strongly recommended that residents that receive medication by mail contact their Doctor to discuss alternative arrangements to receive that medication during this transition period.** 

  10. Who is accountable if the updates are not timely and result in a "black hole" address?

    If you have not been able to update your address anywhere 60 days from receiving the USPS Change of Address notification, please reach out to larimeraddressing@larimer.gov, and we will look into the issue.

  12. Can I appeal changing my road name?

    Affected property owners may request an appeal of any requirement of the Larimer County Road Naming and Addressing Resolution except those pertaining to the road naming hierarchy, sequential numbering, parity, or the naming of unnamed roads. All appeals must be submitted in writing using the form provided by the County to the County Addressing Coordinator with specific details as to the nature of and reason for the appeal request   

    The County Addressing Coordinator shall review the appeal and respond to the submitter with a decision. The County Addressing Coordinator's decision shall be upheld by the County Commissioners unless it is shown by a preponderance of evidence that the decision is inconsistent with or does not promote the intent and purpose of the Larimer County Road Naming and Addressing Resolution.

    If after receiving the appeal response from the Addressing Coordinator, there is still a desire to appeal the decision and be heard by the Board of County Commissioners, here is how that works:

    1. Submit an new appeal to the Addressing Coordinator, to be heard by the County Commissioners.
    2. The grounds for appeal need to show through the preponderance of evidence that you are being singled out and being treated differently than others by the Addressing Coordinator.

    Once the second appeal is received it will be added to the Agenda for the next Commissioners Admin Matters meeting typically held on Tuesdays at 9am.

  13. Why can't GPS coordinates from my cell phone be used to locate me in an emergency?

    Statements have been made that when a caller dials 9-1-1, we know their location by the location transmitted with their phone, and we can just send first responders based on the coordinates. 

    • This is not accurate and is a false statement.

    We receive the latitude / longitude of the handset that ranges in accuracy based on two factors: the wireless carrier’s network AND the age/type of handset used by the consumer.  Location accuracy ranges from 30 -500 meters, and when indoors, it can get worse.

    Once we receive the coordinates of a handset, we still need to, and ALWAYS confirm, the callers' location. This allows for a location verification. We do not ask the caller what are your coordinates; we ask what is the address of the emergency.  The address database we use to support 9-1-1 is the foundation of the 9-1-1 system. The coordinates get us close, but we do not dispatch coordinates; we map the coordinates to our 9-1-1 database to determine a DISPATCHABLE LOCATION.

    First responders do not drive on coordinates, they drive on streets with addresses. We need to be able to communicate a location to a first responder so they can navigate roads, streets, address ranges to find the person that needs help.
