Sammamish commission hears restoration briefing, asks for more volunteers

The Sammamish City Sustainability Commission on a recent agenda focused on habitat restoration, noxious-weed management and volunteer recruitment after a presentation by the city's habitat restoration specialist, Sebastian Ritaka.

Ritaka told the commission there are "19 active restoration sites in the city that cover 42 acres," and described the department's approach to restoring degraded park and green-space sites, training volunteers and managing legally designated noxious weeds. The meeting also included a public comment from longtime resident and Washington native plant steward Mary Wictor, who urged the city to treat tansy ragwort and similar invasive species more aggressively.

The briefing explained why the work matters: many restoration sites begin as heavily disturbed areas dominated by aggressive invasive plants that reduce biodiversity, increase erosion risk and can be harmful to people and animals. Ritaka described a four‑phase approach used to guide management and set work plans, from initial removal and planting through long‑term monitoring.

Ritaka said the city's restoration program relies heavily on volunteers and trained stewards. He reported that the city has 19 master stewards certified through regional training who contributed an estimated 1,755 hours and helped install roughly 2,600 native plants across approximately 2 acres of intensive work. Stormwater stewards have adopted ponds and, since 2023, reported about 788 volunteer hours and 813 plants installed at stormwater sites; Ritaka said the city currently has eight adopted stormwater ponds with three pollinator beds.

On tactics and limits, Ritaka described the city's updated integrated pest management policy (revised in 2023) and said the department prefers physical removal and suppression where feasible and reserves herbicide use for species and settings where other options are not effective (knotweed was cited as one such example). He also described technical shore‑line and erosion control work — including live willow stakes and burlap “island” planting mats used at Beaver Lake Park — that the restoration team implements without volunteer crews because of safety or technical complexity.

Public commenter Mary Wictor urged a more proactive city response to tansy ragwort, saying, "we really need to get at least a few places cleaned up." Commissioners and staff discussed volunteer recruitment challenges: Ritaka said the program gets many high‑school volunteers who often leave after graduation, and that retaining mid‑career volunteers remains difficult. He said he plans events year‑round with more planting in the fall and larger volunteer events on weekends.

Commissioners also discussed outreach and near‑term public events where the commission could engage residents. Staff noted two upcoming community events where a sustainability table is being considered: a Trunk-or-Treat event on Oct. 30 and Frosty Fest tentatively scheduled for Dec. 17. Staff is also arranging a November tour of Republic Services’ materials recovery facility (dates being scoped to Nov. 13 or 14) and has circulated an Eastside Climate Partnership infographic for outreach and grant work. The commission was told volunteer opportunities and event listings are posted on the city website (samamish.us) and that staff posts volunteer events quarterly.

The commission approved its meeting agenda and minutes as routine procedure and later voted to adjourn. The presentation also noted that Sammamish received recognition as a Tree City in 2024, with work credited in part to restoration staff and volunteers.

Questions raised during the presentation included requests for clarity on integrated pest management restrictions, use of mulch and wood chips, erosion‑control timeframes, and how restoration sites are prioritized (Ritaka cited disturbed soils, monocultures of invasive species and mitigation obligations as drivers). Ritaka said he plans restoration work around mitigation requirements tied to park projects and on sites where volunteers and stewards can be effective during the early phases, then rely on stewards and staff as sites require more technical maintenance.

The commission did not take any formal policy votes or authorize new contracts during the meeting; discussions focused on program delivery, outreach and volunteer recruitment.
