Summary
Santa Rosa's landscaping chapter exempts areas planted with intentionally unirrigated native plants from the automatic irrigation system mandate that otherwise applies to every landscaped area in the city. The zoning code also directs plant selection toward species adapted to local climate and soil, and specifically encourages protecting and preserving native species and natural areas on developed sites.
D. Irrigation system required. All landscaped areas, except areas to be maintained with intentionally unirrigated native plants, shall be provided an automatic irrigation system in compliance with Section 20-34.060 (Irrigation System Design). ... F. Landscape design. 1. Plant selection and grouping. ... b. Plants shall be selected appropriately based upon their adaptability to the climatic, geological, and topographical conditions of the site. Protection and preservation of native species and natural areas is encouraged.
Full Breakdown
020(B). 030(A)-(B); those plans must also satisfy the Water Efficient Landscape Ordinance in City Code Chapter 14-30, which controls when the two chapters conflict. 050 sets the substantive landscape standards: a minimum three-foot interior planting width (four feet where trees are planted), height limits at vision triangles, and protective concrete curbing in the R-3 and non-residential districts. 060 except areas intentionally maintained with unirrigated native plants, which are carved out of that mandate entirely. 1 reinforces the preference, directing that plants be selected for adaptability to the site's climatic, geological, and topographical conditions and stating that protection and preservation of native species and natural areas is encouraged, alongside a separate requirement that properties in Wildland-Urban Interface Fire Areas use fire-resistant buffer landscaping under the California Fire Code.
a further ties plant selection to drought tolerance and fire resistiveness as design criteria the Director of Planning and Economic Development reviews when approving a project's landscape plan.
Violations & Fines
Landscape and irrigation improvements, including any native-plant area claimed as irrigation-exempt, must be built exactly as shown on the plans the Director approved. Section 20-34.030(E) makes that installation a prerequisite to final approval or clearance of the project, so a site that installs unapproved plant material or skips the required irrigation system where the native-plant exemption does not actually apply can be held at final building inspection until it is brought into conformance.
