Outflow landing

For purpose of controlling rainwater runoff, a curbed outflow landing made the most sense considering I wanted landscaping in this area. There's no municipal storm drain here. This is corrective measure after having removed a poorly designed concrete walkway that reduced useable back yard space.

So the lowest point was found to be at the threshold on the latch side of the gate. It's the existing concrete lip at the block wall, so all I needed to do was design all downflow to it. Casting the concrete was a two-pour process -- first pour was the curb with a PVC sleeve cast into it, then after curing, the in-fill slab poured and finished trowel-smooth for good surface flow.
