Our office actually assisted on this case. After the community (rightfully) reached out, we contacted Public Works to secure a secondary review by the Acting Urban Forester, which resulted in four of the seven trees being determined as not hazardous and in turn preserved.
From this context, we noted that the appeals process for hazardous trees is still necessary. Accordingly, I amended the legislation you are quoting to still allow the public to submit an appeals process to Public Works (instead of the Board of Appeals).
