You raise some good questions about 'organic' as a standard. There are a
couple of ways to look at the issue. One is to consider the ecological and
biological side of 'organics'. The other is to realize that the term
'organic' (acknowledging our unquestioned debt to Organic Gardening Magazine
and the Rodale family, who coined the phrase) is not a scientific definition,
but part inspiring slogan and part marketing device.

On the bio-ecological side, most of pesticides and fertilizers used in yards
are, to the biochemist, 'organic' (carbon based). This means that the right
microbe can break them down. In a well-run municipal composting operation
(like Huntsville's?), leaf-based composts are probably very low in residues
thanks to the composting critters. Even 'fresh' mulches are probably pretty
dilute, since they are made from leaf drop. You can test the mulch and
compost to verify this.
On the 'practical' side, some organic certification agencies allow use of
municipal leaf composts in light of their low residue, and because this
important soil building resource would otherwise end up in the landfill or be
burned, both terrible decisions ecologically. See what the federal organic
standards say, and check with your local certifiers to see what they allow.

Actually, there are 'transition' categories for farmers in the process of
moving to 'organic' status on farms. You could make part of your garden
'fully organic', while using leaf mulch on the rest (if the leaf mulch isn't
acceptable as 'organic') and making that part 'sustainable/ecologically
In my opinion, sustainability and ecological soundness are more fundamental
than 'being certified organic'. Are you building and protecting your soil?
Are you being very careful about how you use any concentrated form of
nutrient or biocide, whether its origin is 'chemical' or 'organic'? Are you
considering and strengthening the ecosystems and natural communities that
border and interpenetrate your garden - for example, by creating habitat and
encouraging native plants at least along the borders of the garden? Are you
building community with your human neighbors? Does it make sense to turn away
a senior citizen who loves to garden, simply because she wants to slip her
tomatoes a little 5-10-10? These are the key issues, more than seeking the
appealing sounding label 'organic'.
Though I think using municipal leaf mulch or compost on community gardens is
a great idea, you might want to check Elaine Ingham's work on suitability of
different composts to different purposes, based on the 'feedstock' and
microbial makeup of the compost. Second, do be careful if grassclippings are
included in your municipal compost or mulch blend. Some new herbicides used
on lawns are horribly toxic to legumes and reportedly can persist, even
through composting, to kill off your peas and beans.
Though it would take more effort, you could mobilize your volunteers to
collect your own mulch by picking up bags of leaves from yards that don't
spray, and then aging and composting them yourselves at the garden. Local
waste-reduction programs (often sponsored by county engineering departments)
may be delighted to help do this.
Good luck! Keep building that soil, son, you're doing good.
