Well, yeah. That's why they are called city dwellers. There is good reason for the max pre oil city populations. This is a self solving problem. I recommend not sticking around to see it in action.I was attempting to create a model for permaculture that might allow city dwellers to survive post-peak-oil, but now I am figuring that they are just doomed.
But, my opinion on cities is well documented. I'm here to solve this issue.
Nobody is entirely in compliance, ever. Most of the time, people do the same things they have always done, in the same way they have always done it. They aren't checking the rules, and are blissfully unaware of all the rules they are breaking.I thought I had read all relevant code prior to purchase of camper, but only part of the relevant code was available on the city website. I had to dig up the entire code on American Legal Publishing site.
You, are looking at a city blight code. It has one set of rules. Then you are looking at building code, and trying to conform to both. This is possible, and not even that difficult, but not what I would consider effective use of your resources, in your situation.
Building code is valuable, but it's main value is in making sure that something you bought, reached a certain minimum standard. If you pull a slab permit, you are asking to be judged on the standards of the building code. That is your choice.
The antiblight code wants to ensure you are not making an eye sore of parking a car and letting the grass grow. Look at the parts you edited out. They talk about not having garbage in your yard, and mowing your grass, right? ( I had to deal with this with a tenant)
Dealing with these codes separately, as they were written is the key to success. You are not creating a permanent concrete slab as part of a residence. You are doing nothing that involves planning or permits. You are landscaping. If you have any doubts, think of how you would sell your lot. It would be sold as an unimproved vacant lot, right? So nothing you are doing would be of interest to the assessor ( tax value of improvements). Nothing you are doing will result in a transferable building, so nobody needs to be protected from your noncompliant workmanship. So no planners or inspectors from the planners. All you need to do is satisfy the inspector from the Dept that handles blight code enforcement. And for that, you need a concrete slab.
Concrete is a generic term, and soilcrete fits within it. Different formulations of concrete have different strengths, but a 20% cement content in your soil will be tough enough to work for weed control for as long as you like. That is how I would go in your shoes.
But, that is a lot of work. It would be easier to just form it, and call for the concrete to be delivered. Use 2x6's, and dig your perimeter down a bit. Then your slab is 5.5 inches at the edge, and 4 inches throughout. Do it right and you can cut nothing. Look at YouTube videos on pouring concrete, it's work, but nothing you and the 11 year old helper you pull in to help can't handle. 4 boards make your form, another board longer than your 2 shortest is your screed. The truck pours, ( you can find small batch premixed concrete near you. Delivery should be $100-130/yard. 1 yard of concrete is 27 cubic feet, or 81 square feet, 4" thick.) you move concrete with gardening tools, screed, finish with a broom, and you are done. And building code compliant. ( but then you would have to pull a permit, and schedule an inspection before you pour...)
This is not insurmountable, this is a hard day's work for you and a tween. Or a short day's work for a BF. But if you go that route, bring beer and smiles.
