Create tools for city governments and conservation groups that communicate water quality and regulated activities. These tools, templates and examples could then be used by organizations who don't have developer resources or budgets for this kind of work. I put an example up on gethub that displays regulated activities in a city. This could also be done for water quality trends and assessments.
