OBJECTIVE:For each zip code in Washington State, identify 6

i ti dit f h B k h lf d t texisting credits from each Bookshelf product to incentivize.



CHALLENGE:Zip codes often cross watersheds, biomes, and p , ,growth boundaries. But more importantly, zip codes have the greatest granularity in urbanized areas and conversely, the least in less populated areas.
