LID employed by homeowners can play a significant role in decreasing risks of flood and drought while improving the quality of water that flows into streams, rivers, and lakes.
(Undated, likely 2014) By Credit Valley Conservation, Aquafor Beech and Water Canada. Homeowners can play a significant role in decreasing risks of flood and drought while improving the quality of water that flows into streams, rivers, and lakes by adopting LID on their properties. On residential lands, hard surfaces such as the roof, patio, walkways and driveways can all be targeted to collect, treat, and infiltrate runoff.
LID offers communities a way to:
• Protect assets and defer larger investments. LID barriers can slow the flow to storm sewers during intense rain events, giving them more time to process stormwater. In this way, LID helps meet asset management requirements, reduces damage to existing systems, and extends the useful life of infrastructure.
• Save money. Smaller, more frequent events cause costly damage. LID practices encourage infiltration and can help reduce the amount of erosion, and pollutants to creeks, rivers, and streams that leads to regular and often expensive maintenance and lost revenues from beach closures.
• Increase tax revenue. Free space in growing cities is at a premium. The cost of land can be as much as four times the cost of new infrastructure. LID practices require minimal land expropriation, and often fit into existing urban infrastructure, leaving more land available for development and tax revenue.
• Build resiliency and protect the environment. One technology alone isn’t enough to ensure resiliency. Adding LID measures to a treatment train can reduce the frequency of flood- related residential damage due to overwhelmed existing systems. LID can also reduce the flow of contaminated stormwater to surface waters, which can harm aquatic environments, and increase the cost of treatment at the drinking water level.
