I've done drainage forever, this is about how it was done until an engineer showed up with ideas. Although I've never planned a new lot structure, just municipal drainage.This is what landscapers do when planning a backyard. Going from poor memory, I believe you do a 2-3% slope toward drains on a "flat" backyard. To measure your slope, get a 100 foot length of string and stake it at both ends, then measure the elevation change between the two points. Each foot of elevation change = 1%. This is handy for planning your space so that you won't wind up with pooling water when it rains, or if you're having a problem, what you do to fix it.
You gotta see the cobb-job bullshit people use to hook into municipal lines too. Those have to be fixed for them because god forbid the homeowner not get their way.
