I am studying away for my second attempt at this exam at the end of the month and a have a few questions (the first of many posts)
1. With regard to urban patterns. The Radiocentric, Star, and Satellite patterns all seem fairly similar. Enough that I’m not sure I’d be able to pick the correct answer if the 3 were choices on my exam. What is the difference between the 3?
2. From my study guide: “Needle leafed trees, capture moisture, reduce fog, and thus increase the amount of sunlight reaching the ground”. Can someone explain how this works?
3. I have read a few conflicts with regard to the slope of ramps for cars. In my ALS book a max. slope of 8% is stated in one chapter, then, in a different chapter, a diagram is shown with an automobile ramp of 20% max. I also read somewhere else that 15% was the max. to design for. Which is it, and why the discrepancy?
4. Let me know if I’ve got this straight, a conditional use seems to be in play mostly when dealing with the public interest, including putting a building on a site that is not normally zoned for that use. What I gather from the definition of variance, is that such would be requested mainly due to hardship imposed on the land owner, but, unlike a conditional use, a variance could not be used to place a building use on a site that has a different zone attached to it, than is intended by the proposed construction. For example one could not get a variance to place an industrial structure with in a Residential zone.

The typical zoning ordinance lists predetermined conditional uses for any given zone. They are uses that can be made compatible with imposed mitigating conditions. What I gather from the definition of variance, is that such would be requested mainly due to hardship imposed on the land owner, but, unlike a conditional use, a variance could not be used to place a building use on a site that has a different zone attached to it, than is intended by the proposed construction. For example one could not get a variance to place an industrial structure with in a Residential zone. A variance deals with a specific requirement such as setback, height or parking. It could be the result of some real or perceived hardship or to level the playing field for new construction surrounded by older structures that predate current codes.

| 2. Sunlight reflects off fog, if the trees absorb the fog, then the sunlight gets through to the ground (where it doesn't hit the tree)

The difference is not so much how they LOOK, its the differences in their evolution and internal organization. Since its a diagram, look for how the diagram accentuates the differences.
3. I have read a few conflicts with regard to the slope of ramps for cars. In my ALS book a max. slope of 8% is stated in one chapter, then, in a different chapter, a diagram is shown with an automobile ramp of 20% max. I also read somewhere else that 15% was the max. to design for. Which is it, and why the discrepancy?
The CHANGE IN SLOPE should be no more than 8%. In other words, at the ramp at the parking lot, you should not go from LEVEL (0%) to no more than 8%. The 15% (trucks) to 20% (cars) are an ABSOLUTE slope, meaning you can slope over a distance up to 20%.
The 8% is so you don't bottom out your car. The 20% max is so you can make it up the hill.

Crow - Makes total sense about the slope.
Thanks.

| Whenever you see conflicting data, I recommend that you count on the information that comes from an NCARB recommended reference. So, for parking & vehicle slopes, the bible is probably AGS.
