Somerville does not have parking minimums.

Ofc all the buildings pictured were built before that was the case and before there was a protected bike lane. What you mentioned is all good policy but mostly focused on building from scratch.

How would an existing streetscape be handled? Would existing driveways actually be seized by eminant domain?

I don’t understand the complaint about driveway frequency. How would the Netherlands handle that?

The SDS will be for the oil itself, not at the final concentration used in the shampoo or whatever.

Are you sure the final product is at a toxic concentration? Probably the detergent itself is more dangerous as used. That’s just a guess though.
