Trees and Landscaping

The City of Corvallis recognizes the role of urban trees and landscaping in providing environmental, economic, social and aesthetic benefits. Specific benefits provided by a healthy urban forest include improved air and water quality, erosion control and reduced storm water runoff, shading and windbreaks (resulting in reduced energy costs), wildlife habitat, and increased property values. As such, the Corvallis Land Development Code (LDC) includes standards both for the preservation of existing trees, as well as for the planting of new trees and landscaping with development. In addition, the City Urban Forester administers the City's Urban Forestry program, which includes oversight of street tree installation, removal and maintenance.

This page includes links to resources and Code sections applicable to tree preservation standards, street trees, and landscaping requirements associated with development.

Tree Preservation

Within the City, there are several regulations that may prevent the removal of an existing tree(s). These include:

Mapped Natural Features areas, including:
- 100-year Floodplain / Floodway areas (see LDC Chapter 4.5);
- Significant Vegetation areas (see LDC Chapter 4.12);
- Wetland / riparian corridor areas (see LDC Chapter 4.13); and
- Areas with slopes exceeding 35 percent (see LDC Chapter 4.14).
Planned Developments, subdivisions, shopping centers and other approved developments with specific tree-related conditions;
Trees within an Historic District, or on property containing a designated Historic Resource;
Heritage Trees; and
Street Trees (which are under the purview of the City Urban Forester).

If you have questions regarding tree removal or protection provisions for a specific property, please contact Development Services at 541-766-6929.

Street Trees

Street trees (located in the public right-of-way, typically in a planting strip) are under the purview of the City Urban Forester, who works in the Parks and Recreation Department. A permit must be obtained from the City Urban Forester prior to the pruning, removal or planting of any street tree. Existing street trees are maintained by Parks and Recreation Urban Forestry staff.

With development, the LDC requires the installation of new street trees along the development site's street frontage. Street tree obligations must be fulfilled prior to project completion, either through physical installation of required street trees by the development applicant, or through payment into the City's "Tree for a Fee" program. Please review the City's Street Tree Guide for more information regarding street tree requirements associated with development.
