The process of and barriers to environmentally-oriented real estate development : examining the role of organizational structure, project delivery methods and contracts in low impact development
Low Impact Development (LID) is a site planning approach that limits the environmental impact of development on the local hydrological regime. By preserving and mimicking natural landscape features, LID introduces a new site planning and stormwater management paradigm to mainstream real estate …

Performance Evaluation of a Low Impact Development Retrofit for Urban Stormwater Treatment
The goal of Low Impact Development (LID) is to mimic the pre-development hydrologic regime of a catchment through infiltration, filtration, storage, evaporation, and detention of post-development runoff using small-scale hydrologic controls close to the source. A LID facility located in Northern …

Low-impact development in the Assabet River Watershed : site hydrologic design and watershed-scal implications
Low-Impact Development (LID) is a relatively new approach to stormwater management. It aims to mimic natural hydrology through increased recharge and decreased runoff. LID technologies focus on distributed treatment of stormwater, as opposed to traditional centralized management. The potential …

Hydrologic Evaluation of Low Impact Development Using a Continuous, Spatially-Distributed Model
Low Impact Development (LID) is gaining popularity as a solution to erosion, flooding, and water quality problems that stormwater ponds partially address. LID analysis takes a spatially lumped approach, based on maintaining the predevelopment Curve Number and time of concentration, precluding …

Analysis Of Pervious Concrete As A Stormwater Management Tool Using Swmm Modeling
Stormwater runoff occurs when precipitation flows over the ground. Increase in impervious land cover due to urbanization causes excess stormwater runoff and affects the quantity and quality of water bodies. The use of low impact development (lid) controls is highly recommended to reduce the excess …

Sensitivity of Stormwater Management Solutions to Spatial Scale
… runoff volume, producing higher and faster peak flows, and reducing water quality. Efforts to minimize or avoid these impacts, for example by implementing low impact development (LID) practices, are gaining momentum. Designing effective and economical stormwater management practices at a watershed …

Characterization and Removal Efficiency Comparison of Bioretention Soil Media Mixtures
… such as asphalt and concrete, to help reduce the impact of the runoff generated by this increased flow bioretention cells are an often-used method to treat stormwater. These impervious surfaces do not allow rainfall to infiltrate, and the water runs off into receiving water bodies such as rivers …
