San Carlos planning commission hears draft EIR for Northeast Area Specific Plan; air quality and greenhouse gases flagged as unavoidable impacts

The San Carlos Planning and Transportation Commission on March 16 received a staff and consultant presentation on the draft environmental impact report (EIR) for the Northeast Area Specific Plan, a 145‑acre effort to guide a mixed‑use district that preserves industrial uses while allowing new housing and multimodal circulation improvements.

Senior Planner Rendle Buso told commissioners the plan would rezone selected blocks to allow multifamily housing, update floor‑area and height controls, and create a community benefits program that could allow increased height for non‑residential projects in exchange for public amenities. Staff’s buildout projection for the plan area is roughly 1,890 housing units and about 4.5 million net new square feet of non‑residential development over a 20‑year horizon.

Aone Danielson of David J. Power Associates, the environmental consultant, summarized the draft EIR’s findings and the CEQA process. Danielson said the draft EIR identifies two categories of significant, unavoidable effects: regional air‑quality pollutants (smog‑forming nitrogen oxides and reactive organic gases) and greenhouse‑gas emissions. Both findings reflect the scale of the plan and projected vehicle trips; Danielson noted these outcomes are common for plans of this magnitude and that achieving statewide carbon‑neutrality goals for 2045 depends on actions beyond the city’s regulatory toolbox.

The draft document models mitigation measures and several alternatives. Staff presented a reduced‑scale alternative that would shrink overall development by about 20% (sufficient to avoid one type of air pollutant exceedance) and an enhanced transportation‑demand‑management (TDM) alternative that would increase minimum TDM performance from 25% to 30%, which modeling shows could better align trip growth with service‑population growth. The no‑project alternatives (no new development and growth under existing plans) are also included in the EIR.

Commissioners asked detailed questions about the EIR’s modeling assumptions, TDM evidence and enforcement, utility and infrastructure upgrades, and compatibility with nearby facilities such as the airport. Staff said utilities and service agencies prepared assessments (including a water‑supply assessment) and concluded the system can serve the projected growth, and that infrastructure construction impacts are typical and can be mitigated; project‑level issues such as below‑grade parking in areas of high groundwater will be addressed when individual projects apply for permits.

Commissioners also pressed staff on how the city would monitor and enforce TDM performance. Staff acknowledged that monitoring and enforcement require resources and that the citywide TDM program will need to identify a manager or funding approach to verify reductions and impose remedies if projects fail to meet commitments.

Chair Clemens opened the hearing for public comment; none were received in person or via Zoom. The commission voted to close the hearing for tonight while the draft EIR remains open for written public comment through April 16. Staff said they will prepare a final EIR that responds to substantive comments and return the final EIR and the specific plan for future commission and city council action.

Next steps: the draft EIR public review period continues through April 16, 2026; staff expects to publish a final specific plan and final EIR in the spring and present them to the commission and council for certification and potential adoption later this year.
