Using the lazer level we assessed the topographical drainage area feeding water to future systems. 

After calculating placement and sizing, I came up with four planting plans. The plants were chosen to withstand heavy stormwater inundation with minimal maintenance needs. 

The hole for the microbioretention is dug the day before planting. A layer mix of sand, gravel, soil and compost provides a 4′ substrate that will act as a filtration system along with the plants. Jesus inspects the dig.

One of the four microbioretention systems remains flooded with water and sedimentation after heavy July storms. The dig needs to be drained and allowed to dry before planting. Jack and Charlotte use a hose to empty the hole into an adjacent stormdrain.

The plants arrive and we get to work laying them out and getting them in the ground.

Mulching around the plants.

Juan and Jesus break up the soil to add an outlet of riverjack stones.

The finished microbioretention system incorporated existing trees for maximum filtration.

As the storms roll in and the workshop ends an Eastern Swallowtail Butterfly samples nectar from the new garden plants.

Charlotte explains some maintenance specifics to Karen while she admires her new garden.

Jack points out some of the finer points of the species.

After planting and mulching Charlotte and Mike give it a deep watering to help get the plants established.
