Unfortunately we have a variety of smells, from the unabated bodily waste (homeless, drunks) to the poorly functioning sewer system.

However, we know why the sewer system isn't functioning well - low flow toilets. Yes, the lack of water to move effluent down the system causes it to get stuck and then start drying and it creates a pretty horrible smell.

The homeless situation is out of hand due to the unfortunate confluence of well meaning people and a lack of framework to deal with the chronically homeless.
