Summary

Fremont requires developers to avoid disturbing nesting birds during the February 1 to August 31 nesting season, citing the Migratory Bird Treaty Act and state law making it unlawful to take birds, nests, or eggs. Preconstruction surveys and buffer zones apply if work can't be avoided.

Nesting Birds. New development projects with the potential to impact nesting birds through tree or shrub removal shall implement the following measures prior to removal of any trees/shrubs, grading, or ground disturbing activities: (A) Avoidance. Proposed projects shall avoid construction activities during the bird nesting season (February 1st through August 31st).

Full Breakdown

) any migratory listed bird" and that Cal. Fish & Game Code Secs. 5, and 3800 prohibit the "take, possession, or destruction of birds, their nests or eggs," with disturbance causing nest abandonment counted as a take (Sec. 020(b)(1)-(2)). Sec. 050(b)(2) turns those findings into a standard development requirement: new development with potential to impact nesting birds through tree or shrub removal must first try to avoid construction activities during the bird nesting season, defined as February 1st through August 31st. If work must proceed during that window, a qualified biologist must conduct a preconstruction survey to identify nesting activity; if nests are found, protective buffer zones sized by the biologist in consultation with the California Department of Fish and Wildlife (CDFW) must be established around them, and construction may not begin within the buffer until a biologist confirms the young have fledged and are foraging independently.

The chapter also separately protects burrowing owls, requiring preconstruction surveys, avoidance during the February 1 to August 31 nesting/roosting period, and passive relocation only where avoidance is infeasible (Sec. 050(b)(1)).

Violations & Fines

Chapter 18.218 requirements are imposed as conditions of approval on development projects (Sec. 18.218.040), enforced through the planning manager's authorization before construction may proceed; a biologist's written determination that nesting birds have fledged, or that burrowing owls have vacated a site, must be submitted to the planning manager before construction activities can continue in an affected area (Sec. 18.218.050(b)(1)(D)).

Frequently Asked Questions

Can a Fremont developer remove trees during bird nesting season?
Sec. 18.218.050(b)(2) directs projects to avoid construction during the February 1 to August 31 nesting season. If that is not possible, a qualified biologist must survey for nests first, and any active nests found require a protective buffer zone sized in consultation with CDFW until the young have fledged.
What law does Fremont cite for protecting nesting birds?
Sec. 18.218.020(b) cites the federal Migratory Bird Treaty Act, which bars taking any migratory listed bird, and the California Fish & Game Code Secs. 3503, 3503.5, and 3800, which prohibit taking, possessing, or destroying birds, their nests, or their eggs, including through nest-abandonment disturbance.
Does Fremont protect burrowing owls too?
Yes. Sec. 18.218.050(b)(1) requires preconstruction surveys by a qualified biologist for burrowing owl habitat, avoidance of occupied areas during the February 1 to August 31 nesting/roosting period, and passive relocation only as a last resort when avoidance is not feasible.
