What is a Critical Areas Ordinance (CAO)?
The CAO is a set of regulations established to protect sensitive environments, referred to as critical areas. The intent of the CAO is to conserve and protect the ecological functions of natural environments and to reduce exposure to risks, such as landslides and flooding. Critical areas defined under the Growth Management Act (RCW 36.70A.030) include the following ecosystems:
(a) wetlands;
(b) areas with a critical recharging effect on aquifers used for potable water;
(c) fish and wildlife habitat conservation areas;
(d) frequently flooded areas; and
(e) geologically hazardous areas.
Why is the Bellevue Critical Areas Ordinance (CAO) being updated now?
The Washington State Growth Management Act (GMA) requires all cities and counties to review and update critical area regulations every 10 years. Periodic review focuses on alignment with current federal and state policies, and incorporates best available science to management and protection of critical areas.
What is the timeline for this CAO update?
The City of Bellevue is required to adopt code amendments by the end of 2025.
What regulatory changes are anticipated?
Based on review of best available science and regulatory review, CAO updates may be recommended. The City is in the early stages of this project and will be assessing what changes may be needed to ensure consistency with federal and state policies and best available science. Areas of the CAO that are likely to be assessed include environmental and habitat protections, impact allowances and mitigation requirements, best practices for critical area protection, and updates to improve clarity and administration.
Are Shoreline regulations being updated at this time?
No. Shoreline areas are regulated under the Shoreline Master Program (SMP). See LUC 20.25E for shoreline regulations. The City of Bellevue is not scheduled to update shoreline regulations until 2029.
How do I know if I have a critical area on my property?
Critical area regulations apply to sites containing critical areas and/or their buffers. Publicly available mapping can be referenced as a guide, but site-specific study by a qualified professional may be necessary to assess site conditions. Public resources for critical area mapping include:
- Bellevue MapViewer
- King County iMap
- Reach out to the Bellevue Development Services Department to confirm requirements for a specific project
What can I do in or near a critical area?
Land uses in or near critical areas are regulated to protect the resource and/or to protect human health and safety. Generally, impacts to critical areas and their buffers should be avoided, minimized to the extent feasible, and any unavoidable impacts must be mitigated. See LUC 20.25H.055 for a list of uses and developments allowed within critical areas.
