“Dear Sonoma County Planning Commission,
Please consider potential noise impacts to the breeding success of this critically endangered species prior to amending noise restrictions currently in place.
The linear marshlands along the Petaluma River upstream from Ellis Creek to the Petaluma Marina also support the state-threatened California Black Rail (Latterallus jamaecensis cortuniculus). This species could also be negatively impacted by increased noise pollution and industrial activity at this location.
Thank you for your attention to this issue.”

"...these (egret and heron nesting) sites may be subsequently abandoned in response to changes in the frequency or intensity of human activity. Therefore...noise, artificial lights, conveyer activity...are likely to increase the risk of abandonment."
