I have recently volunteered to make a web map for a local non-profit. The map will be pretty basic. It needs to display Lane county, Oregon split into multiple districts, with a "central office" location for each district. I plan on building this in my spare time over the summer, and I want to be able to hand this off to them with very little risk of it needing any sort of future maintenance.
I'm currently unfamiliar with most non-ArcGIS solutions, so any advice would be appreciated.
