California Council of ASLA (CCASLA)

The California Council of the ASLA (CC-ASLA) is comprised of the four California Chapters (San Diego, Southern California, Sierra, and Northern California) representing approximately 1350 California landscape architects. The CC-ASLA is the coordinating body regarding state-wide legislative and licensure issues. CC-ASLA monitors bills proposed by the State Legislature that could impact the profession and/or the public realm. CC-ASLA is also involved with the regular sunset review process regarding the Landscape Architecture Technical Committee; the State organization that oversees the licensure of landscape architects. CC-ASLA invests time and resources from membership dues to keep an eye on state regulatory, legislative, and citizen actions and initiatives that affect the profession and our communities.


All 50 states have recognized that regulation of landscape architecture is necessary to protect the public health, safety, and welfare. All but three states regulate the profession through a practice act, which requires a license to practice the profession and use the title ‘landscape architect.’ The remaining three states have enacted title act statutes, which is a weaker form of regulation that allows anyone to practice landscape architecture if they call it something else. A practice act is important because of the real danger to clients and the users of these public and private spaces: physical injury, property damage, and financial ruin.
