3 plant palette The Plant Palette identifies shade, understory and small trees, shrubs, groundover, perennials and ornamental grasses appropriate for the projects identified within the Urban Greening Plan and consistent with the policy direction defined by the Urban Greening objectives. The Plants defined as part of this plant palette do not represent an exhaustive list of appropriate or approved plants; they were developed to identify contextsensitive plant recommendations for El Cerrito s streets, parks, and open spaces. This palette may be used to provide plant guidance to private projects interested in achieving the benefits identified by this Plan. This Palette is a living document and may be updated over time to better reflect changing environmental conditions. If the Plant Palette and the City s current Master Tree List are in conflict, the current Master Tree List will take precedence.

8 PLANT PALETTE: STROLLING STREETS Landscaping along strolling streets should compliment commercial uses and provide a pleasant sidewalk environment for pedestrians. Plants were selected for their foliage and size, and should be maintained so as to not block signs or impede pedestrian movement. Figure 01.

9 PLANT PALETTE: CREEK INTERPRETATION STREETS AND PROJECTS Creek Interpretation streets and projects make use of distinctive vegetation to identify underground creek channels and to highlight green infrastructure. These riparian trees, shrubs and groundcover were identified for their look and feel, as they re often used near creek banks, and were selected for their environmental benefits.

10 PLANT PALETTE: ARTERIAL STREETS Plants along major arterial streets should help buffer pedestrians from automobiles, providing a pleasant walking environment. Trees were identified for their ability to filter air pollutants and improve environmental air quality, without creating significant tripping hazards or conflicts with utilities. Figure 17.

11 PLANT PALETTE: BIOFILTRATION Biofiltration plants are commonly used in green infrastructure projects to filter stormwater runoff and improve water quality; they can help spread, sink and store water to reduce erosion and water demand. Biofiltration plants are generally drought tolerant and provide additional environmental benefits, such as pollination services or wildlife habitat.

13 PLANT PALETTE: POLLINATORS Urban environments are reducing the quality and quantity of pollinating plants, making it difficult for wildlife species, such as birds, bees and butterflies, to find food. Creating contiguous pollinator-friendly landscaped areas can begin to address this issue, bringing these species back into our urban environments.
