LID Technical Advisory Committee

At the final meeting of the LID advisory process on August 12, 2010, Ecology presented a draft LID proposal outline. Committee members provided input that is recorded in the meeting summary for the August 12 meeting, below. They also submitted written comments on the draft proposal that Ecology will consider as it develops the requirements for permit reissuance.

The Technical Advisory Committee worked with the Implementation Advisory Committee to define the scope of low impact development techniques, criteria for determining the feasibility of LID techniques, a LID performance standard, and a deadline for implementation. The materials on this page provide a record of the committee’s work.
