Construction: finish grading

The finish grading process is another critical handoff moment as a number of elements such as [[curbs, sidewalks, groups|soils and vegetation start to come together to create the functional and aesthetic value of a site. The same supervision and communication that was put into controlling ESC in earlier stages is also required during finish grading. Careful attention to detail is still needed in these final phases to ensure the success of the final product

Construction steps:

• Soil Media:

1. Backfill or sling material from outside of the LID facility at the lowest possible speed to avoid loss of component material.
2. Apply material in 150-300 mm lifts until the desired elevation and thickness, allowing for positive flow.
3. Wet material between lifts, allowing for drying before backfilling/slinging another lift.

Low Impact Development. A stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.
