Low Impact Development (LID) are principals and practices that mimic the natural hydrologic processes.

Due to increases in impervious surfaces due to Urban Development less stormwater has the opportunity to infiltrate into the soil and water table therefore causing surface water levels to fluctuate drastically damaging fish habitat and the surrounding environment. Low Impact Development (LID) principles include: reducing impervios surfaces (footprint), retaining native vegetation, and reducing the overall surface water runoff leaving a site. This can be accomplished by utilizing dispersion, infiltration, and pervious pavement options. 

Project Updates

Currently the City is reviewing and amending existing regulations to incorporate Low Impact Development principles in all projects. We need your feedback to let us know what approaches we should use to reduce impervious surfaces, retain native vegetation, and/or reduce flows.

Goals

The goals for the review and update of City regulations include: improving water quality/reduce runoff, incorporate Green Infrastructure and other new technologies, and to meet the Washington State National Pollutant Discharge Elimination System (NPDES) Permit requirements by December 31, 2016.

Next Steps

Our next steps in this process include: review of existing Development Code, Technical Stakeholders meetings, Fall Open House, and incorporate Public/Stakeholder comments into recommendations for code amendments.
