Full Breakdown

D. Within that design standard, subsection 5 bars landscape plans from specifying any species the California Invasive Plant Council, known as CAL-IPC, has identified as invasive specifically in the San Francisco Bay Area, tying the prohibited list to CAL-IPC's regional inventory rather than freezing it into the Municipal Code text. The same design-standards subsection layers on related water-conscious planting rules: at least 75 percent of non-turf plants must need only occasional, infrequent, or no summer water once established, judged against reference guides such as the Sunset Western Garden Book or the UC Cooperative Extension's water-needs guide, and irrigated turf area is capped at 25 percent of the landscape with turf barred on slopes steeper than 25 percent above hardscape. 116, on that submittal before it can be approved.

Violations & Fines

A landscape plan that specifies a CAL-IPC Bay Area invasive species is not eligible for approval of its Landscape Documentation Package under Section 4.16.108, and installing prohibited species without correcting the plan exposes the responsible party to the City's administrative penalty process under Section 1-12-415, with each day of noncompliance treated as a separate violation.

Frequently Asked Questions

Can I plant CAL-IPC-listed invasive species in my San Leandro landscaping?
Not on a covered project. Section 4.16.116.D.5 bars new or rehabilitated commercial, industrial, or larger residential landscape plans from specifying any species CAL-IPC has identified as invasive in the San Francisco Bay Area.
Does the invasive species ban apply to my small backyard garden?
It applies to developer-installed residential landscapes over 2,500 square feet and any residential landscape over 5,000 square feet under Section 4.16.116.D. Smaller owner-installed home gardens outside that threshold are not covered by this design standard.
Who checks landscape plans for prohibited invasive species in San Leandro?
The Zoning Enforcement Official reviews the Landscape Documentation Package required under Section 4.16.108, and the landscape professional preparing the plan must certify compliance with Chapter 4.16's design standards before the package is approved.
