The Building Permit - Not Quite Enough

My last post was just prior to heading down to City Hall to talk about my building permit. Although I did not get my permit, I have to say they were incredibly helpful and friendly.
Pulling out my slightly better than amateur drawings, I could see the man holding back his chuckles. I wondered if he could see that I, too, was trying not to chuckle. After all, if a real contractor was applying for this permit, they would certainly be held to a much higher standard. As the "dumb homeowner", I'm granted a little bit of leeway. In reality, the plans are not bad.
There were a couple of details missing from my plans; how I was going to tie the slab overpour to the existing, how I was going to secure the base plate to that slab and the real doozey... how far from the centerline of the street.
Well, that last point has opened up a can of worms. It seems that my rectangular shaped lot has one side measuring 110 feet and the other side measuring 155 feet. Anyone who has taken 7th grade geometry can quickly see that this is impossible - it is a rectangle, after all, and two sides must be equal in length. This discrepancy is caused by the fact that my lot was originally 110 and 155, but the prior homeowner deeded the extra nub of land back to the community. So now, city hall has records which show the proper shape, but the wrong dimensions. Other than having to go out and buy bigger paper, I am faced with a challenge. Do I replicate the mistaken dimensions? Or do I correct the mistake and report the proper dimensions, which will, no doubt, trigger a full survey of my lot - at my expense?
I think I will just keep drawing and try to get back to city hall next week.
