El Cerrito Rain Gardens

Rain Garden Perspective Drawing by Gates and Associates

As part of the stimulus program and various water quality initiatives, El Cerrito got funding to add some rain gardens along San Pablo Avenue, the main commercial street in my neighborhood. A huge percentage of the area is covered with concrete, so when it rains the water has nowhere to go and the streets can look like this photo I took in May; sometimes I feel like I should get out a kayak. To help mediate that, the city redid two sections of sidewalkswith plantings set below the grade of the street. Instead of draining straight to the bay, stormwater will now flow from the streets and sidewalks into planting areas where sediment will drop out of the water and pollutants and trash will be filtered by the plants. There are 600 total linear feet of basins in the two separate areas, calculated to treat 1.23 acres of paved surface; the San Francsico Estuary Institute is going to monitor water quality to see how big of an effect the gardens have. There’s a podcast about the project here. It’s a nice use of plants to address an infrastructure issue.

The plantings are all natives. Juncus, leymus, and a grass that looks like a melica are the main species, peppered with some yarrows, two monkey flowers, two California fuchsias, two Ribes speciosa, several Verbena lilacina, two wild roses, a redtiwg dogwood, and a Doug Iris. There are one or two blooming plants in each planter right now, not a big impact, but just enough to focus the eye as you walk past each one.

The El Cerrito Patch says the cost of the project was $350,000 for the two sections of rain gardens.
