Full Breakdown
54 addresses invasive species in two places. 030, Definitions, defines 'invasive plant species' as 'species of plants not historically found in California that spread outside cultivated areas and can damage environmental or economic resources,' and it notes that invasive species may be regulated by county agricultural agencies as noxious species, pointing landscape designers to the California invasive plant inventory and the USDA invasive and noxious weeds database for reference lists. ' That is discouragement, not a codified ban or an enumerated local prohibited-species list, so Redlands relies on the statewide Cal-IPC inventory rather than maintaining its own catalog of banned plants.
010(C)(5), frames 'avoiding invasive plants' as part of the chapter's broader habitat-protection goal alongside choosing local native plants and climate-adapted non-natives. 020. The chapter was last updated by Ordinance 2917 in 2021, building on the 2009 ordinance codified as Ordinance 2724 section 1.
Violations & Fines
Because section 15.54.100(A)(1)(g) discourages rather than prohibits invasive species, there is no per-plant fine tied to this specific clause. A landscape design plan is still reviewed at plan-check under section 15.54.050 and must reach a certificate of completion under section 15.54.130 before final inspection, so reviewers can flag invasive selections during that process, and section 15.54.060 authorizes penalties for noncompliance with the chapter as a whole.
