A fourth Democrat has announced her candidacy for a seat on Princeton Council. Anne Waldron Neumann, a former member of the Princeton Environmental Commission and Site Plan Review Advisory Board, has joined newcomers Tim Quinn and Leticia Fraga and incumbent Jenny Crumiller in the race for the two seats that are up for grabs. Ms. Crumiller issued a formal announcement this week that she is seeking re-election.

Incumbent Patrick Simon has said he will not seek re-election.

Affordability is the most pressing local issue to Ms. Neumann, who ran for Borough Council in 2010 but was defeated in the primary. “I grew up in Princeton,” she said in her release, “and I’m passionate about preserving our many diverse neighborhoods. How many Princetonians know that a third of all Princeton households, based on income alone, would be eligible for affordable housing?”

 Ms. Neumann chaired Princeton Borough’s Affordable Housing Commission in the last year before consolidation and took part in a Princeton Future initiative supporting local retail. She has served on the Princeton Democratic Organization’s executive board for 10 years and currently chairs its Local Issues Committee.

Among the bullet points she lists as her vision for Princeton are keeping property taxes as low as possible to protect diversity in age and income, making it possible for residents to age in place, using zoning laws proactively and shaping development to suit the town’s needs, providing affordable housing, and preserving the character of existing neighborhoods.

Ms. Crumiller served on Borough Council before consolidation and has been a member of Princeton Council since the merger of Borough and Township three years ago. In her first term on the consolidated Council, she has served on the Planning Board, the IT Committee, the Ordinance Harmonization Committee, Traffic and Transportation, and Public Works.

“I have done my best to make our new government inclusive and transparent and to look for cost savings without diluting the quality of services. There is more to be done, I know what needs to be done, and this is why I am seeking re-election,” she said.

Developer-driven growth and the loss of affordable homes due to teardowns are her major concerns. Taxes, increased traffic and speeding on local roads, and making sure government is transparent are among her other priorities. The work of harmonizing the ordinances of the former Borough and Township has been a challenge, she said.

“We have made good progress, but the work is still ongoing, most particularly the work with the land use ordinances. Land use rules are really important because they have concrete effects on neighborhood character and on affordability. We have to study these carefully to get it right.”

Ms. Crumiller’s campaign chair is Walter Bliss, a former board member of the Princeton Public Schools. Her treasurer is Peter Lindenfeld, a founding member of the Princeton Community Democratic Organization. The candidates running for Council and mayor will speak March 20 at an Endorsement Meeting held by the PCDO. Members of the PCDO will then vote on which candidates to endorse.
