Transportation impact fee methodology update was on the May 21 study session agenda

What the records say

Materials published ahead of the May 21, 2025 Planning Commission meeting included an agenda bill for study session item 4A, 'Transportation Impact Fee Update' ¹. The bill states no action is requested and the session is intended to give the commission the chance to discuss the update and provide input ¹. The city collects transportation impact fees to fund system-wide transportation improvements that mitigate demands new development places on the transportation network ¹. Staff say the update responds to the 2024 Comprehensive Plan's change from a vehicle-trip level of service to a multimodal level of service (MMLOS), which considers pedestrian, bicycle, transit, and other non-motorized modes alongside vehicle trips ¹. That change generated a new 20-year transportation project list within the Comprehensive Plan; total cost to plan, design, and construct it is approximately $850 million, of which the TIF program is expected to fund $100 million, about 12% ¹. The last major TIF update was in 2019, with minor annual cost indexing since ¹. The update is expected to use 'person trips' rather than vehicle trips, update trip estimates within the 12-year TIF planning horizon, update the eligible project list, calculate the proportionate share of costs attributable to growth, and develop a new TIF cost schedule ¹. The agenda bill asks the commission about keeping a citywide fee versus moving to zone-based fees (including possible 5–15% reduction overlays in areas such as Canyon Park) and about reduced fees for affordable housing, noting reductions likely cannot exceed about 25% without losing sufficient revenue to fund planned projects ¹. The packet does not establish the meeting's outcome ¹.

• The May 21, 2025 Planning Commission study session agenda listed a 'Transportation Impact Fee Update' as item 4A; the staff bill requests no action and seeks discussion and input ¹.
• The update responds to the 2024 Comprehensive Plan's shift from vehicle-trip to multimodal level of service (MMLOS) and is expected to use 'person trips,' update the 12-year trip estimates and eligible project list, and produce a new fee cost schedule ¹.
• The 20-year transportation project plan is approximately $850 million, with TIF expected to fund about $100 million (12%); the last major TIF update was in 2019 ¹.
• The commission was asked to weigh citywide versus zone-based fees, including possible 5–15% reduction overlays in areas such as Canyon Park, and whether to reduce fees for affordable housing — with reductions likely capped near 25% so revenue remains sufficient ¹.
• The packet does not establish the meeting's outcome; staff plan to develop a draft TIF cost schedule after feedback from the Planning Commission and City Council ¹.

Why it matters

Transportation impact fees are charged to new development to help pay for the road and transit improvements that growth requires, so a methodology change can affect both the cost of new homes and businesses and the funding available for transportation projects. The record ties the update to a roughly $100 million TIF share of the city's 20-year project plan ¹. The agenda shows this was a discussion stage: the session requests no action, and staff say they will develop a draft TIF cost schedule only after gaining feedback from the Planning Commission and City Council ¹. Residents watching whether fee levels or affordable-housing reductions change will need to follow that later draft, which the record does not date ¹.

What changed / what's next

• The May 21, 2025 Planning Commission study session agenda added 'Transportation Impact Fee Update' as a discussion item — the first major TIF methodology revision since 2019, per the staff agenda bill ¹.
• Staff say they will develop a draft TIF cost schedule after receiving feedback from the Planning Commission and City Council; the record provides no date for that schedule or a formal proposal ¹.
• The available records do not establish the meeting's outcome, so whether the commission endorsed a citywide or zone-based approach, or any affordable-housing reduction, is not yet documented ¹.
