Critical Areas Regulations

The protection of Lynwood’s critical areas is essential to preserving our natural environment, and protecting the public’s health and safety. Protecting critical areas helps reduce exposure to risks, such as landslides or flooding, and maintains the natural elements of our landscape. Once the functions and values of our critical areas are lost, they can be very costly, or even impossible to replace.

Critical areas addressed in these regulations include:

Ducks in a stream

The City of Lynnwood adopted Ordinance No. 3193 on May 23, 2016, which amends our Critical Areas Regulations, chapter 17.10 of the Lynnwood Municipal Code (LMC). The new regulations became effective June 1, 2016. All cities and counties in Washington State are required to adopt critical areas regulations under the Growth Management Act (GMA). As defined by the GMA, "critical areas" include the following areas and 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. [RCW 36.70A.030(5)] Counties and cities are required to incorporate Best Available Science (BAS) in developing policies and development regulations to protect the functions and values of critical areas. The City of Lynnwood underwent several months of public outreach and stakeholder review prior to adoption. The new regulations incorporate public feedback, best available science, and Washington Department of Ecology standards.
