Landscape Architecture Design

Good design requires addressing and balancing a variety of competing goals.


Landscape Architects provide design services that help integrate a transportation facility within its setting, creating a visually pleasing travel experience for all who live, work, and travel in California. As part of the Project Development Team (PDT) Landscape Architects play a vital role in developing a multi-modal transportation network that coexists harmoniously with the natural and built environment.

Landscape design involves working with a wide range of materials and products. While some state transportation departments maintain an APL, or "Approved Products List" Caltrans Landscape Architecture program does not maintain an APL. Products that meet Caltrans specifications are able to be used on construction contracts by virtue of the fact that they meet our specification requirements.
