LIMA — The city of Lima is participating in the Bloomberg Philanthropies 2017 Mayors Challenge and is seeking public input in an online survey that could put the city in line for a donation. The survey, located at http://bit.ly/2irUo41, asks what those surveyed believe is the greatest challenge facing Lima and why, as well as what unconventional solution could help address this issue and how this issue would be categorized, be it health, safety, the economy and so on. Surveys are being accepted until Sept.
