Environmental

Washington's Puget Sound region has experienced declining water quality from stormwater runoff. Real estate developers are typically required to implement Low Impact Development (LID) techniques to address this. LID techniques include:

AMaximum impervious surface coverage without mitigation
BBioretention cells, permeable pavement, green roofs, and rain gardens to reduce runoff✓ Correct
CChanneling stormwater directly to Puget Sound as quickly as possible
DReducing landscaping to minimize water use

Explanation

Low Impact Development (LID) techniques mimic natural hydrology by slowing, filtering, and infiltrating stormwater on-site using bioretention cells, rain gardens, permeable paving, and green roofs. These are required by many Puget Sound area jurisdictions to protect water quality.
