Planning commission continues Ring Lake Estates hearing after Ecology, sewer and stormwater concerns

At a recent Medical Lake Planning Commission meeting, commissioners held a public hearing on the Ring Lake Estates preliminary plat and voted to continue the application to the commission's next meeting after agency and public comments raised questions about wetlands, stormwater design and sewer capacity.

City Planner Alisa summarized the development-review steps and the outstanding technical issues that must be resolved before a final decision. “This process is not about whether you like something or dislike something, but rather, does it meet the criteria?” Alisa said, explaining that the commission is asked to judge the proposal against municipal code and SEPA-related requirements.

The applicant, Ross Anderson, an engineer with Centier Engineering, said the team believes the layout is feasible but acknowledged missing technical detail. “We think with the application that we put forward, that we have a feasible route to move forward,” Anderson said, adding the project needs additional soils, wetland and hydraulic calculations before construction-level plans can proceed.

The proposal shown in materials provided to the commission is for roughly 102 lots, of which the applicant identifies 101 as buildable parcels after reserving one lot for a lift station and swale. The staff report states the proposal currently averages about 2.67 units per acre against the city’s R-1 maximum density of 7.3 units per acre. The applicant has requested Planned Unit Development (PUD) adjustments, including a reduced minimum lot size (from the city’s 6,000-square-foot standard down to 5,000 square feet) and narrower right-of-way dimensions.

Why the commission continued the hearing

• Department of Ecology indicated the site may contain additional wetlands beyond the five shown in the applicant’s critical areas report. Ecology’s map in the commission packet marked several additional wetland areas that the agency asked to be investigated.

• City staff and outside agencies raised infrastructure questions: the city’s wastewater system currently lacks capacity in the collection zone that would serve the new subdivision; staff said the development cannot be approved unless capacity is created or the applicant funds necessary upgrades. The city’s public-works review also flagged concerns about whether proposed roadside swales and on-site stormwater measures provide adequate capacity and treatment before water reaches wetland areas and downstream properties.

• The SEPA (State Environmental Policy Act) record and checklist submitted with the application are incomplete in places or used an older form. City staff said the SEPA determination will likely be revised after the applicant supplies additional studies and responses to agency comments.

What the application seeks and the city’s key mitigation requests

• Preliminary plat for Ring Lake Estates (applicant materials label about 102 lots; staff counted 101 buildable lots).

• Requested PUD adjustments: reduced lot size (6,000→5,000 sq. ft.) and reduced right-of-way/roadway widths.

• Staff-listed mitigation items in the draft mitigated determination of nonsignificance included a city‑approved sediment-and-erosion-control plan to be in place before ground-disturbing activities; pedestrian crossing improvements to connect to the Medical Lake trail (to be coordinated with Washington State Department of Transportation because Laffey Street/State Route 902 is involved); and a plan to reroute or enlarge sewer infrastructure so the lakeshore lift station is not overloaded.

Agency responses summarized in the staff packet

• Department of Ecology: flagged potential additional wetlands on the site, reminded the applicant of hazardous-waste handling and noted a required stormwater general permit must be applied for at least 60 days prior to construction.

• Department of Fish and Wildlife: reviewed the critical-area report and did not object to the applicant’s approach to habitat mitigation in the materials provided.

• Department of Archaeology and Historic Preservation: requested a professional archaeological survey before ground-disturbing work because mapping indicates potential archaeological resources.

• Department of Social and Health Services: raised non‑specific concerns about water production and systems; city staff said they will coordinate further with that department.

Public comments and neighborhood concerns

Dozens of residents spoke at the hearing or submitted written comments. Common concerns included protection of wetlands and wildlife, downstream flooding and sump‑pump impacts, noise and dust from earthwork, long-term maintenance costs the city could face, and the effect of new households on local services such as schools.

- Mary Robertson, a Medical Lake resident, urged stronger wetlands protection and public education about wetlands benefits.

- Angela Gary, a county resident who lives adjacent to the proposed site, said the wetlands and the trail attract wildlife and argued for fewer, larger lots to preserve habitat.

- Lisa Wenner described repeated flooding at the site and warned the school district would face added capacity pressure if the subdivision added several hundred new students.

- John Lewis and several other neighbors raised technical questions about swale performance, the need to excavate rock for filtration galleries, and the risk of increased runoff reaching downstream yards.

Applicant response and construction feasibility

Ross Anderson told the commission his team has engaged consultants, including wetland specialists, and believes the design can be made to meet regulatory requirements. He said some on‑site work already undertaken followed a forestry permit issued by the Washington Department of Natural Resources (DNR). Anderson cautioned the commission that many engineering details — including exact swale cross-sections, stormwater galleries and any required blasting to remove rock — are matters for the next, construction‑plan phase.

City planner and process notes

City Planner Alisa reviewed the steps that follow a preliminary-plat approval: SEPA revisions, agency coordination, final plat engineering review and a final decision by city council (the council is the ultimate decision maker after the planning commission issues its recommendation). Alisa said the city’s concurrency code requires certain infrastructure (especially transportation and sewer capacity) to be in place or funded before a development can be approved.

Votes at a glance

- Motion to move selection of chair and vice chair later in the agenda: passed (voice vote; mover recorded in meeting transcript). Note: procedural motion unrelated to the plat.

- Motion to approve the agenda as amended: passed (voice vote; details in meeting record).

- Motion to approve minutes as presented: passed (voice vote).

- Motion to table items 6(b) and 6(c) until the next meeting (to allow further participation by an absent commissioner): passed (voice vote; outcome recorded as tabled).

- Motion to continue or extend the Ring Lake Estates public‑hearing decision to the commission’s next meeting (applicant requested time to revise materials and respond to Ecology and other agencies): passed (voice vote). The commission set the file to return at its next regular meeting for a new decision.

Next steps

The applicant indicated it will work with wetland specialists and state agencies to resolve Ecology’s concerns, produce revised SEPA materials and provide additional stormwater and sewer plans. City staff said they will circulate revised materials and a new SEPA notice if the record is materially changed. The planning commission’s recommendation will be based on the record available at the time of its decision at the next meeting.

The record will also reflect agency input required by the Project Review Act and the State Environmental Policy Act; any final approval will be conditioned on required permits (including Ecology’s stormwater general permit) and construction plans that meet city and state technical standards.
