Low Impact Development (LID) Principles

The City of Mountlake Terrace, along with over 85 other Western Washington municipalities, is required to make LID the "preferred and commonly-used approach to site development." The City is updating its codes and standards to be consistent with the Low Impact Development Principles conditioned in the 2013-2018 National Pollutant Discharge Elimination System (NPDES) Western Washington Phase II Municipal Stormwater Permit.

What is LID?
LID is an approach to land development (or re-development) that works with nature to manage stormwater as close to where it falls as possible. The LID approach seeks to mimic pre-development conditions to the greatest degree possible, thereby reducing surface water runoff and stabilizing fluctuations of the water level of creeks and streams.

LID employs principles such as preserving and recreating existing vegetation, especially trees, and minimizing impervious surfaces.

By implementing LID principles and practices, stormwater can be managed in a way that reduces the impact of built areas and promotes the natural movement of water within an ecosystem.
