Tree Protection in Sunnyvale, CA: What Residents Actually Need to Know

If you live in Sunnyvale or are thinking about moving there, tree protection are one of those things you probably won't think about until they affect you directly. Sunnyvale has 2 specific rules on the books covering different aspects of tree protection, and some of them might surprise you.

Parkway Planting

Sunnyvale requires a minimum of one city tree per lot in new development and bars anyone from planting in the public right-of-way, including the parkway strip, without a permit from the superintendent of trees and landscaping. Only species on the official tree list may go in without special written approval from the city.

Key details: Permit required: Written permit from tree superintendent to plant. New development standard: Minimum one city tree per lot. Height limit: 24 inches for shrubs/plants in tree easement. Tree-base clearance: No ground cover within 3 feet of tree base. Application lead time: 48 hours before planting work begins.

Planting a tree in the right-of-way without a permit, or planting an unlisted species without written superintendent approval, is unlawful under Sections 13.16.040(b) and 13.16.060(a). A parkway-strip hedge, wall, fence, or planting that violates the twenty-four-inch height limit or three-foot tree-base clearance in Section 13.16.100 is a declared public nuisance; the city can abate it under Chapter 9.26 and collect the cost as a civil debt against the property owner.

Heritage & Protected Trees

A tree the Sunnyvale city council designates a heritage landmark under Chapter 19.96 needs two permits before it can come down: a protected tree removal permit and a landmark alteration permit, and the heritage preservation commission must approve any material change to it at a public hearing (Muni Code Sec. 19.94.050(a), 19.96.090).

Key details: Heritage resource definition: Expressly includes trees, Sec. 19.96.040. Designation authority: City council. Extra permit: Landmark alteration permit + tree removal permit. Review body: Heritage preservation commission, public hearing. Appeal: To city council within 30 days.

Removing or altering a heritage-designated tree without both the landmark alteration permit and the Chapter 19.94 tree removal permit is enforceable by the director of community development, who may serve a notice requiring correction, or refer the matter to the city attorney for injunctive relief or other legal action, under Sec. 19.96.160. Unpermitted removal of the underlying protected tree also triggers the Chapter 19.94 civil penalty of up to $50,000 per tree.

This is not one of those rules that cities tend to ignore. Sunnyvale actively enforces its heritage & protected trees requirements.
