Access Sonoma Broadband

Person using laptop outdoors on trail


It has become impossible to lead one’s life, or conduct one’s business without adequate broadband access. Throughout the world broadband is becoming recognized not as a luxury, but instead - a necessity.  

Unfortunately, rural and low income communities, as well as communities of color across the nation face economic disenfranchisement and strained economies due to inadequate broadband access. To address this challenge, the Sonoma County Economic Development Board has formed Access Sonoma Broadband (ASB) to work with communities to close the digital divide through infrastructure design/deployment, access, and affordability, and implementing digital equity.

Access Sonoma Broadband Action Plan

Exploring the creation of a public broadband entity to close Sonoma County’s digital divide.

On June 8, 2021, the Sonoma County Board of Supervisors approved the Access Sonoma Broadband Action Plan. The purpose of the plan is to explore the creation of a publicly governed broadband entity. This entity could deploy, own, and manage broadband infrastructure within Sonoma County, reducing the cost barriers for broadband providers, and closing the regional digital divide.

Infrastructure Design and Deployment

  • In the fall of 2022 the County of Sonoma, in partnership with Golden State Connect Authority, applied for and received a $499,554 grant from the California Public Utilities Commission’s Local Agency Technical Assistance grant program. The funding is planned to provide a refined high-level broadband network design for unincorporated areas with little or no internet service and low-level, construction-ready design for priority areas. The scope of work for this grant program is anticipated to be completed within 18 months of the grant award (June 2024).

Access and Affordability

  • To further broadband accessibility and advanced adoption, the EDB has been awarded a $300,000 grant from the Federal Communications Commission (FCC) Affordable Connectivity Program (ACP). The grant is intended to be used to drive awareness and enrollment in the largest broadband affordability program in the nation’s history. Building upon current community partnerships, the FCC has issued grants to support partner organizations nationwide to serve as trusted community messengers about the ACP and to better equip agencies with funding to pursue innovative outreach strategies to reach historically unserved and underserved communities. Visit Internet for All Now to learn more about ACP, find out if you’re eligible, and apply today.

Digital Equity

  • It has become impossible to lead one’s life, or conduct one’s business without adequate broadband access. Throughout the world broadband is becoming recognized not as a luxury, but instead - a necessity.
  • Unfortunately, un- and underserved communities across the nation face significant challenges due to inadequate broadband access. Lack of adequate broadband service is an issue that affects health, education, economic success, and overall quality of life. Closing the digital divide is a priority for Sonoma County.

Digital Divide in Sonoma County


As technology evolves and our demand for internet bandwidth increases, existing broadband infrastructure has become outdated in many low density communities and is not able to support their current demand for bandwidth. Fortunately, there are state and federal grant programs that fund broadband infrastructure deployment in unserved and underserved communities that do not have access to high speed internet, defined in California as services capable of providing a minimum speed threshold of 6 megabits per second download and 1 megabit per second upload. To see if you may qualify for funding opportunities, please run a speed test at:

You may also visit the California Interactive Broadband Map to view the current status of connectivity throughout California that identifies areas that may be eligible for grant funding.


It is imperative that students have access to fast, reliable, and affordable internet services and technology in order to complete school assignments remotely at home and at school. The Sonoma County Office of Education works diligently to ensure all school districts have access to high speed internet. These efforts involve partnerships with internet service providers and with Corporation for Education Network Initiatives in California (CENIC). For more information on current connectivity throughout Sonoma County’s school districts, please visit:


Reliable communication is absolutely necessary for individuals to stay alert of emergencies in Sonoma County. Sonoma County staff proactively work with cellular providers on improving cellular service throughout the County, exploring opportunities to deploy infrastructure in areas lacking cellular coverage, upgrade antiquated and failing landline systems, and create overall redundancy in our networks to ensure communities have access to reliable and resilient communications during emergencies and natural disasters.

North Bay North Coast Broadband Consortium (NBNCBC)

In 2007, the California Public Utilities Commission (CPUC) authorized the California Advanced Services Fund (CASF) to provide grants to bridge the “digital divide” in unserved and underserved areas of the state. In 2010, CASF was expanded into three accounts, and one of those accounts became the “Rural and Urban Regional Broadband Consortia Account” whose intended purpose, pursuant to AB 1665, is to facilitate the deployment of broadband services by assisting infrastructure grant applicants in the project development or grant application process. More information about the CASF grant program and these regional consortiums can be found on the CPUC website.

In 2014, the North Bay North Coast Broadband Consortium received grant funding from the Rural and Urban Regional Broadband Consortia Account to create a 4 member county broadband consortium in partnership with Mendocino, Marin, Napa, and Sonoma counties. NBNCBC still remains operational today and its current efforts focus on assisting internet service providers apply to broadband infrastructure grant programs for deployment projects in unserved areas, as well as advocacy for broadband related legislation. There are several reasons why we believe participating in a regional consortium is beneficial:

  • The rural areas of all four counties have a great deal in common: low population density, agriculture, tourism, geographical challenges to broadband deployment, and the resulting urban/rural digital divide
  • Broadband connectivity does not stop at county lines, and coordinating county planning reduces capital expenses to deploy broadband.
  • Regional broadband deployment also encourages network redundancy and improves reliability, which reduces broadband outages due to network damage.
  • Regional cooperation also reduces costs to any one county by a sharing of resources, (such as GIS mapping, expertise, and information) and developing regional projects.

How You Can Help

The California Public Utilities Commission maintains the State Broadband Coverage Map which identifies coverage areas. Currently this data is self-reported by carriers to the Federal Communication Commission’s Form 477 which has been determined to misrepresent the actual availability of broadband through the United States.  By verifying the actual services available at your home or in your community, you will be confirming or refuting carrier supplied information and helping the CPUC provide a more accurate description of coverage in California. This confirmation process is known as ground proofing and allows communities to pursue broadband infrastructure grant funding if determined unserved and eligible.

Take the CPUC Broadband Survey

The information you provide by completing the survey will be incorporated into the consumer feedback layer, and be used to validate or invalidate provider's service availability information. 

The CPUC has two ways for you to provide survey feedback data:

  1. Mail-in the paper survey: Simply complete, sign, and mail via US Mail to the address at the bottom of the survey.
