Low Impact Development (LID) Stormwater Management¶

Rainwater & Storage • Est. CapEx: $1,250 USD • Lifespan: 7–15 Years

Technical Overview¶

A comprehensive urban design approach that manages stormwater runoff close to its source using small-scale, decentralized measures such as rain gardens, permeable pavements, and rainwater harvesting. This manual provides regulatory and technical guidance for developers and municipalities.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Rainwater & Storage
Capital Cost (CapEx)	$1,250 USD
Power / Energy	100% Gravity / Zero Power
Target Scale	Village / Community (200–1,000+ people)
Standard Lifespan	7–15 Years
Technology Maturity	Commercially Available
Primary Mechanism	LID integrates site design principles (e.g., minimizing impervious cover) and stormwater control measures (e.g., bioretention, infiltration trenches) to reduce runoff volume and peak flow. Techniques rely on infiltration, evapotranspiration, and rainwater harvesting to mimic natural hydrology.
