Liberty Lake planning commission approves greenhouse gas goals, sends draft to City Council and state Commerce

The Liberty Lake Planning Commission on June 25 voted to recommend that City Council approve draft goals and policies for the city's greenhouse gas subelement and forward the package to the Washington State Department of Commerce for review.

Consultants from Parametrix presented the draft and advised commissioners the subelement was built from the city's emissions inventory, state policy effects and a menu of measures published by the Department of Commerce. "The greenhouse gas inventory identified buildings, transportation, and waste as the largest sources of emissions in Liberty Lake," consultant Maddie Cheek said during the presentation.

The subelement emphasizes reducing emissions from buildings, transportation and waste and lowering per-capita vehicle miles traveled (VMT). Proposed local actions discussed at length included incentivizing efficiency upgrades (for example, permit-fee reductions), encouraging local solar and small-scale battery storage, expanding active-transportation and transit connections, and exploring lower-carbon diesel alternatives for heavy equipment.

Commissioners pressed staff and consultants on implementation detail. Commissioners asked what "incentivize" means in practice; staff advised the city's direct tools are limited but cited fee reductions, public education and partnerships with utilities and regional agencies as the primary levers. "In the case of the levers that the city has, we don't have a lot other than incentivizing through fee reductions for desired actions," a city staff member said.

On building energy, commissioners recommended adding examples such as cool roofs and weatherization to the policy language or listing them as implementation examples. On local solar and storage, presenters said solar is common on new construction in Liberty Lake and that return-on-investment varies by house orientation and site; consultants offered examples ranging from roughly 12 to 25 years depending on exposure and system size. Battery backup remains comparatively expensive: one speaker noted a residential battery costs "about 10,000 right now." Avista, the local utility, was described as reluctant to provide incentives for distributed storage in the near term; staff said Avista is not investing in those incentives until 2031.

Panelists also discussed community-scale options such as community solar or shared battery arrays and the value of pairing storage with distribution-level planning to improve grid resilience.

On transportation, the consultants said they used cell-phone-based trip data from a vendor called Replika to estimate VMT and that the measure is best used to track changes over time rather than as a single absolute. The subelement recommends increased mixed-use development, active-transportation network improvements and continued coordination with Spokane Transit Authority to reduce VMT.

Lighting and "dark sky" certification were raised in questions. Staff said Liberty Lake has lighting standards based on a regional dark-sky ordinance and that pursuing formal "dark sky certification" is possible but would require additional technical review; LED adoption was described as market-driven rather than state-mandated.

Waste and wastewater strategies were discussed. Staff reported Spokane County captures methane at its landfill and uses beneficial reuse; by contrast, Liberty Lake Sewer and Water District told staff that its recent facility design and concrete holding tanks make methane capture infeasible at that site. Staff recommended focusing on water conservation and coordination with county systems where capture or beneficial reuse is feasible.

After the presentation and discussion, a commissioner moved to recommend City Council approval of the greenhouse gas subelement goals and policies as presented; another commissioner seconded. The planning commission then voted in favor with no recorded opposition. The commission directed staff to forward the draft to City Council and the Department of Commerce for review and preapproval; staff said the package is planned to be workshopped at City Council on July 1 and that the full comp plan package is expected to return to the commission in the fall.

The commission's recommendation does not itself adopt implementing programs or fee changes; commissioners and staff repeatedly noted that specific incentive programs, fee schedule changes and code amendments would require separate Council action and further implementation work.
