Dianne Herrin

I know the policy decisions we make today determine our future and the future of our children. I am running to lead our Commonwealth down a sustainable path that reduces reliance on the gas industry, pipelines, and dirty energy. I am running to ensure our policies reflect our values, and that we prioritize infrastructure, our local economy, and fair financing of public schools.  

I possess the skills for governing, which include persistence, commitment, strength, clear communications, and the ability to listen to others and think critically. As Mayor of West Chester, I have used these skills and improved upon them, as I have proudly served my community. 

Most importantly, I believe in the common good. I am running because, in a time when 71 percent of Americans are angry about the state of the country, 66 percent are fearful, and only 17 percent are proud, we need a real change in leadership. We need leaders who think in terms of the social whole — of what’s best for the community, the common good. As Irving Kristol wrote, “In the same way as men cannot for long tolerate a sense of spiritual meaninglessness in their individual lives, so they cannot for long accept a society in which power, privilege, and property are not distributed according to some morally meaningful criteria.”

I will bring my forward-looking policies, my skills, and our shared values to Harrisburg for all the residents of the 156th legislative district.

West Chester Borough Sustainability Advisory Committee     2015–2018
This advisory committee to West Chester Borough Council reviews land development plans for sustainability features and has developed a reward program for incentivizing green building in the Borough. The Committee also supported the Borough’s mosquito management plan, which focuses on prevention and aims to eliminate pesticide spraying while ensuring health ad safety.

West Chester Community Rights Alliance     2015-present
Formed the West Chester Community Rights Alliance to expand the Borough’s home rule charter to include protections for a healthier and cleaner environment. The update to the Borough's charter – known as the Environmental Community Bill of Rights – passed as a ballot measure with 73% of the vote in the 2015 election, demonstrating strong bipartisan support.

West Chester Borough Tree Commission     2014-2018
Authored ordinance designed to protect and restore the Borough’s aging tree canopy. The new law creates additional financial support for residents and building owners faced with condemned street trees and prioritizes tree replanting and tree preservation. Trees increase real estate values, draw customers to retail districts, reduce energy use and costs during the summer, clean the air, reduce stormwater runoff, and improve quality of life in the Borough.

West Chester Borough Leaders United for Emissions Reduction     2006 – 2015
This municipally-endorsed ad-hoc committee performed the Delaware Valley’s first community-wide greenhouse gas emissions inventory, authored the nation’s first officially adopted ordinance requiring ENERGY STAR efficiency standards for new commercial construction, and created/implemented a successful Climate Action Plan which led to community-wide greenhouse gas reductions of 10% over 2005 base year levels.

West Chester VOTE     2011—2012
Member/Communications Lead: “Take the Politics Out of Public Education"
Created strategic communications materials and contributed other efforts to West Chester VOTE. WC VOTE endorsed a fiscally responsible, diverse, bipartisan team committed to excellence in public education. This bipartisan group of citizens initiated the successful write-in campaign for the West Chester Area School District Board in 2011, described as “massive” by the Daily Local News, resulting in more than 41,000 write-in votes, and culminating in our candidates taking the majority on the board within 2 years and busting Tea Party control.

Moms for the Future     2004 – 2007
This grassroots group of young mothers – an offshoot of Chester County Moms for Kerry – advocated for sustainable public schools in our communities. Moms for the Future brought five local public school districts, Krapf Buses, and The Energy Co-Op together in a successful effort to convert all five districts’ bus fleets to a locally-grown, environmentally sustainable B20 biodiesel blend, thanks to a uniquely structured PA-DEP umbrella grant.
