New Jersey nonprofit Hopeworks ‘N Camden took full advantage of National Day of Civic Hacking by partnering with GIS company ESRI, New Jersey American Water, the Center for Family Services, the city of Camden, the U.S. Department of Housing and Urban Development and the White House.

Add a handful of tech-savvy Hopeworks’ youth and local civic hackers, and you’ve got yourself a righteous civic hackathon, complete with an appearance from Drew Zachary, a policy advisor at the White House Domestic Policy Council.

The theme for the weekend was mapping the impact of Camden’s Promise Zone Plan, which aims to remedy the conditions that led to the White House declaring part of the city a Promise Zone in 2013. Here’s a map of the current environment for youth and education in the city, made by participants over the weekend.

That’s just a taste of what went down across the river for this year’s civic hacking holiday. Participants spent time building a database and supplementary storymap visualizing the impact of the Promise Zone plan across sectors, such as health and wellness.

Once published later this summer, Hopeworks plans to educate the Camden community on how to use the tool on a day-to-day basis.

“This is another example of how a strong public-private partnership can work to benefit a community,” said Mayor Dana L. Redd in a statement. “This will be a valuable resource while providing opportunity for feedback and interaction within the community. There is so much positive momentum and progress in terms of economic development, job creation, leveraging private investment, promoting healthy living and improving educational outcomes currently taking place throughout the City of Camden.”

Stay tuned for more information on the storymap. But, in the meantime, here are some photos from the hackathon.
