Construction next door - need a contractor's input

[AD720]

Here is an etiquette question for you folks -

The vacant lot next to our house is finally becoming something. I understood when we bought the house that there is a good chance there will be some construction there sooner than later and was prepared for the noise. No problem - I armed myself with a print out of the noise ordnances. So far they have been respectful of them (even I though I think 7am is too early for power tools).

My issue is not with noise but with the crew using the sidewalk in front of my row home as a staging/storage area to the extent of leaning the temporary fencing, boards and other stuff against the side of my house as well as my fence.

I have been in email contact with the builder and calmly and courteously addressed this concern to which he said he would certainly take care of. This was two weeks ago and just this morning I walked outside to walk to work and there were saw horses and an orange highway-road-caution sign thing leaning against my house. I said "excuse me" but none of the workers seemed to speak english.

Am I being a jerk?
