The photographs presented here extend coverage of "Layering the Experience" from the July 2008 issue of WaterShapes (pages 50-61); they highlight an important approach seen but not discussed in detail in the published text. We thank Kathy Marosz of Vision Design & Watershapes (San Diego) for providing us with these images.

Setting the slot
One of the keys to this project's organization and hydraulic performance had to do with establishing the overflow slot in the kiddie play area — a feature that effectively connects the pool's vanishing edge detail to the surge tank.

The challenge: The slot was to take a sinuous course through a space in which the bottom of the play area was to rise up to the slot from a variety of depths. It wasn't long before we recognized that we needed a way to keep the form for the slot steady, as well as finely adjustable, so we could be sure other activity in the area wouldn't compromise its being dead level.

To make it work, we mounted the forms on threaded rods imbedded in the grade beams. This meant that we could re-level the forms before that part of the shoot occurred — an idea that made so much sense that we supported the forms for the vanishing edge, planter and spa in the same manner.

This approach did the trick: The slot is dead level and works like a charm.
