Jeffco commissioner candidate profile: Donald Rosier, Republican


Bio: As a 5th generation Coloradoan and Jeffco native (born and raised in Arvada), my roots run deep in our state and county.  I have been married to the same wonderful woman for 32-years, father to 3 great kids, I am a registered professional civil engineer, and former 2-term county commissioner. 

 Why are you running for county commissioner? 

I am very concerned with the direction of the county and the actions taken by the commissioners over the past few years.  With the over regulation and everchanging rules stifling small business, their desire to raise taxes as the county and the nation suffers from the worst inflationary pressure in over40-years, to their decision to underfund the Sheriffs department, Jefferson County needs a leader who listens to them and represent their interests.  I am that proven leader who listens to and engages with the community all while working to develop solutions to our critical needs.   

 What is your biggest strength as a candidate? 

As a former 2-term (8-year) Jeffco commissioner, small business owner, and professional civil engineer, I know what the job entails and can immediately address the issues that need attention on day one.  I have a proven track record of actions that streamlined county operations, reduced taxes, increased economic vitality and improved the health safety and well being of residents across the county.  I am a proven servant leader.  

As a commissioner, what would you do to support economic development in Jefferson County? 

From proposing and then implementing the Countywide Economic Development plan during my first year as commissioner and serving on the board of the Jeffco Economic Development Corporation, working with the many county-based companies to expand all while encouraging new industries to locate within Jeffco, I have the real-world experience and proven results needed to keep Jeffco competitive in today’s economic climate. 

Do you see the county taking a role in a Jefferson County homeless shelter? 

Over the past few years, Jeffco has seen a significant rise in the homeless population.  Weather due to mental health issue, addiction, escaping an abusive situation or financial impacts, the homeless situation in Jeffco and the surrounding communities needs to be address.  However, this should not be just a County Government centric activity.  With all the great non-profits and faith-based organizations in the area, the county should work with these knowledgeable and experienced groups to encourage and promote an action plan.  Non-profits have a proven tract record of providing services quicker and much more efficiently that government. 

Your seat incorporates sections of west Jefferson County (Conifer, Pine, etc.) where the wildland urban interface is a major discussion point. What issues specific to that area would you address? 

I am very familiar with the Wildland Urban Interface (“WUI”) and the associated health and safety issues that impact residents and business alike.  We have studied and talked about the numerous concerns, and it is time to act and address these health and safety issues.  Over 8-years ago, I worked with county staff, community stakeholders, residents and business throughout the county to implement the very successful and hugely beneficial slash program.  This is a public private partnership that has led to the elimination of hundreds of thousands of yards of combustible material from our mountain communities. 

What role would you play in wildfire mitigation? 

I will take an active role.  We need a leader who fully understands the issues, listens to the community, and who can bring together a collaborative approach to wildfire mitigation.  I have been and will be that commissioner again who engages with the community, industry professionals, and stakeholders to develop and execute on a comprehensive wildfire mitigation plan with stated metrics and deliverables.  Our county is looking for someone to champion actionable solutions with measurable results and I am that individual.   

 What are the two most significant issues facing the county today and how would you propose to address them? 

Crime and the county budget.  The crime tsunami that has taken over Jeffco is in direct response to the underfunding of the Sheriffs Department along with a soft on crime approach taken by the county.  This coupled with the confusing and ever-changing business regulations during the COVID pandemic imposed by the commissioners led to a devastating financial situation for many businesses in the county and adversely affected the county budget.  In 2011 I led the county out of the economic crisis of the great recession without cutting services or raising taxes, and I can do it again.     

What one part of county government would receive more attention if you were elected?  

It is time our county commissioners work with our sheriff’s department and not against the brave men and women of the law enforcement community.  This defund the police policy, publicly supported and acted upon by a few County elected officials, has proven to be a failed policy that not only has seen a rise in crime but puts the lives of county residents at risk every day. 

What is your vision for the future of Jefferson County? 

Jeffco is a wonderful place to live, work, play and learn.   However, with the rising crime rate, increased cost of living, strangling and ever-changing regulations on business, and the aggressive approach taken towards our children and families for remote learning during the pandemic, this positive opinion has changed for many.  Jeffco needs a commissioner who doesn’t hide behind video calls, who is not afraid to engage in constructive discourse, who takes action on items that are of concern for residents, and who represents the constituents who elected them.  I am that proven leader who is ready to serve.
