Smart Growth, Strong Voices, and a Sustainable Future

Where Justin Martinez stands, and what he has already done on Thornton City Council since 2023. The mayor’s office is where that same work continues.

Protecting Our Water

Justin has made environmental protection a priority on City Council. In 2024, he spearheaded a comprehensive review of Thornton’s environmental policies, including water quality and oil-and-gas regulations. He has also advocated for stronger protections and accountability around water and sewage systems in mobile home communities, including supporting state legislation to require remediation of water-quality violations without shifting those costs onto residents. In 2025, Justin voted to support Adams County’s efforts to cap and seal abandoned oil wells in our area. Justin will continue to advocate for smart environmental policies that protect our water, air, and our community.

More Ways to Get Around

With his background in regional economics and planning, Justin has been a strong advocate for transportation that gives residents more choices in how they get around. He serves on the Denver Regional Council of Governments Board of Directors and is the chair of the North Area Transportation Alliance, working with communities across the northern metro area on transportation solutions, mobility, and congestion. As mayor, Justin will make sure Thornton has the transportation infrastructure it needs to grow responsibly and sustainably.

Protecting Thornton from the Impacts of Data Centers

In 2026, Justin proposed a temporary moratorium on new and expanding data centers while Thornton considers the potential impacts of these facilities on critical infrastructure and resources. The City Council adopted the moratorium. Going forward we will need our leaders to make sure the policies around new data center development serve to protect our quality of life, not the interests of wealthy tech companies.

Elections, Not Appointments

Justin believes Thornton residents — not political insiders — should have the final say in who represents them. In 2024, he supported changing the city charter so that qualifying City Council vacancies can be filled through a special election rather than simply through appointment.

Heard in the Neighborhood

Justin believes that good government starts with listening to the people it serves. He brought Ward meetings back as an opportunity for residents to meet directly with their councilmember, raise concerns, and have a voice in decisions affecting their neighborhoods.

Building Public Trust

Justin believes that good government starts with transparency. From reviving Ward meetings to establishing strong privacy guardrails, he has worked to make local government serve the people who live here by protecting residents’ privacy and giving them a stronger voice at City Hall.
