I'm a total noob regarding the corruption effects of C3C, so on whether we really need a city even on distance 2 from the capital I'm going with anarres' opinion.
Taking into account that Rotterdam has already been founded, how about a city placement as in the following pic (no fancy dots as in pp's pic, just regular paint dots
):

My personal choice would be to found the blue dot city first, than the yellow one. both have access to forests for shields, and the blue dot city reaches 5 food surplus with the cow irrigated.
Also, considering the granary, I'd prefer building at least one other settler before starting the granary.
Will go and play the turns tonight.
