Getting your Trinity Audio player ready...

VIDEO and PRESENTATION. From San Mateo County Planning and Building‘s “Community Workshop for Draft Sea Level Rise Policies” on Tuesday, September 30th, 2025 from 10:00am to 12:00pm, as a hybrid meeting, to review the proposed approach to sea level rise in Plan Princeton with the establishment of a Sea Level Rise Overlay District. The presentation and a recording of the workshop are available below. Note that Plan Princeton area is located at Pillar Point Harbor.

The workshop was presented by Senior Planner, Summer Burlison and Bharat Singh, Planning Services Manager. SMCo Planning anticipates sharing a draft Princeton plan with the community in early 2026.

Topics Covered

  • Preferred plan zoning.
  • SLR overlay district and adaptation plan
  • Cease development
  • Relocation or removal
  • Recorded deed restrictions
  • SLR overlay real estate disclosures
  • “Fair share” contribution for SLR improvements
  • Transfer of development rights (TDR). Per Senior Planner, Summer Burlison, SMCo Planning presented TDR as an option to pursue after the adoption of the Plan Princeton Land Use Plan. An action item would be included in Plan Princeton for the County to establish this voluntary, implementable TDR program for property owners.
