LID Construction

Phases of LID Construction

1. Pre-Construction:

• Verification of design
• Tendering and contract
• Pre-construction inspection and protocols
• Mobilizing, access and perimeter controls
• Erosion and Sediment Control (ESC)

2. Construction:

• Excavation and mass grading
• Backfill granular and pipes
• Finish grades: inlet, outlet, biomedia and plants

3. Post-Construction:

• Address deficiencies
• Assumption protocols

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.

Soil, sand and minerals washed from land into water, usually after rain. They pile up in reservoirs, rivers and harbors, destroying fish-nesting areas and holes of water animals and cloud the water so that needed sunlight might not reach aquatic plans. Careless farming, mining and building activities will expose sediment materials, allowing them to be washed off the land after rainfalls.

Gravel, or crushed stone of various size gradations (i.e., diameter), used in construction; void forming material used as bedding and runoff storage reservoirs and underdrains in stormwater infiltration practices.
