LID Cost Analysis vs. Conventional Development


A common question about low impact development is, "What does it cost?"

Compared to conventional development techniques, a low impact development design can often cost equal to or even significantly less than conventional development due to savings on infrastructure costs. Also, because LID designs frequently incorporate open and green space, sale prices in LID residential developments are often higher due to demand for the neighborhood features offered by this type of residential setting.
