Cowlitz County approves preliminary plat for Whiskey Flats subdivision with staff conditions

The Cowlitz County Board of County Commissioners voted to approve the preliminary plat for Whiskey Flats, a 20-lot, 3.6-acre cottage-housing subdivision near Gassman Road and West Side Highway in unincorporated Cowlitz County, during its May meeting.

The approval follows a planning commission public hearing and a split recommendation: the planning commission voted 4-2 to recommend approval without granting a requested waiver on maximum unit size, while county staff recommended allowing a modification that would let up to one‑third of the units have up to 1,400 square feet of habitable space rather than the county's 1,200-square-foot cap. Planning staff presented the project as using the county's cottage-housing provisions to allow attached single‑family units on individual lots with private yards.

Adam Trimble, planning manager, summarized the competing recommendations and the modification request: "the developer requested a modification to go up to 1,400 square feet for a third of those 20 units, and staff was recommending approval of that." After discussion about septic, road design and other conditions, a commissioner moved to approve the preliminary subdivision plat "with the staff recommended waiver request," and the motion passed.

Why it matters: the approval clears a key early regulatory step for the subdivision but does not authorize construction. Commissioners and staff repeatedly stressed that several technical approvals and designs remain before building permits or lot creation are issued. The board and staff emphasized that a final plat, detailed septic designs, and street and utility designs must be approved before vertical construction can begin.

Key details and conditions from the discussion: - Project scope: 20 lots on a 3.6-acre site using cottage-housing provisions; single‑story attached units, each with a one‑car garage and a driveway space for a second vehicle as envisioned in the preliminary plat. - Unit-size modification: county code caps "habitable space" for cottage housing at 1,200 square feet; the developer requested a modification to allow up to 1,400 square feet for up to one‑third of units. Staff recommended approving that modification; the planning commission had recommended approval without the modification; the Board approved the staff-recommended approach. - Septic and water: the site will use on‑site septic systems and public water. Staff and commenters noted that septic designs are conceptual now and must be proven feasible during the permit and final‑plat phase. As Trimble explained, the developer has "done some due diligence" with the environmental health unit, but a constructible septic design is required at permitting. - Roadway mitigation and timing: the developer agreed to fund and deliver a design to realign Gassman Road at its intersection with West Side Highway to reduce the skew of the junction; the county will retain that design and seek construction funding through the county's six‑year Transportation Improvement Program and external grants. County Engineer Susan (county engineer) said the developer "would do the design and complete the design as part of his subdivision design and dedicate that right away to the county. Then we would put that on our 6 year plan and start working on grant funding." Staff said the intersection construction will depend on funding availability; having the design improves grant competitiveness. - Homeowners association and maintenance: the development will have an HOA; staff said HOA documents must show responsibility for on‑site stormwater and shared septic systems where applicable and will be reviewed by planning and legal staff before final plat. - Public-safety and fire access: the subdivision will be on public water with hydrants; the county fire marshal will review access and hydrant spacing as part of permit review.

Discussion highlights: neighbors repeatedly raised concerns about well impacts, septic clustering, on‑street parking spilling onto Gassman Road, and whether the road realignment would be completed before construction. Several residents said they had received notices late; staff clarified that planning commission public hearings require a minimum 10‑day notice and a 300‑foot mailed notice radius under county code. Residents also asked about wells drilled on nearby parcels and whether covenants could bar new wells for irrigation; staff said well permits run through the environmental health unit and state agencies and that a shared HOA well for common‑area irrigation would need to be permitted and included in HOA documents.

Next steps: preliminary plat approval allows the developer to move to final plat and engineering design phases. Staff noted preliminary plat approvals expire after five years if not finalized. Before final plat and building permits, the developer must deliver constructible engineering designs (including septic and the Gassman Road realignment design), recorded HOA documents acceptable to county review, and any other required permits and mitigation.

Endnote: The commission framed the decision as balancing property‑rights and neighborhood impacts; commissioners said they view the county code process as the means to manage remaining technical issues rather than to block development outright.
