My new town is pretty flat. By far the flattest of any I have worked in. They also are in need of a stormwater management plan. Can anyone point me to a plan for a city/town that is pretty flat? What things should we keep in mind as we develop it. This is actually a fairly challenging engineering problem.
I would think a city in coastal-ish FL, LA, NC, SC, etc have tools or ways to think through this.
Maybe not exact analogs, but close - flat coastal areas at/very near sea level.
I think your goal is to be gravity fed structures to man made structures below the common surface elevation.
Talk to Arlington Heights, IL (2nd/3rd ring NW Chicago suburb). The landscape is fairly flat without many nearby surface water courses.
So over the decades they've had to build large manmade water retention and/or detention facilities.
