Applicant proposes wet pond + bioretention to address water quality; experts say infiltration would better protect fish habitat

Project engineers told the Kitsap County hearing that the Meadowview development’s water-quality system is built around two wet ponds with bioretention features downstream of the ponds. The design team said the combined pond-plus-bioretention approach addresses both coarse and fine pollutant loads raised by the public.

Miss Heffern, the project’s civil engineer, said the project includes two wet ponds sized for water-quality and flow-control, and bio-retention swales through which pond outflows will pass. She said the team selected a “list 2” compliance path under Kitsap County’s stormwater manual, implemented full-dispersion where feasible at the north lakefront, and used bioretention at outfalls downstream of the ponds. “The stormwater pond, the wet pond helps, capture the larger particles that…
