To Davis Tree Commission:
In regard to the DISC proposal (Item 6B on your agenda this evening), I support your subcommittee's recommendations and encourage you to recommend them as a "baseline feature".
Given that the size of the proposal is already known, recommendation of a specific number of trees should be achievable (as it was during the previous iteration of the proposal).
I understand that the developer is proposing to satisfy shade requirements via the use of solar panels or trees. Unfortunately, this type of "choice" will increasingly be used by developers, as we've already seen in regard to Sutter Hospital's expansion. It may be that developers generally prefer solar panels, to help them meet other requirements (and to claim that a given proposal is "green", while simultaneously eliminating "greenery" in regard to trees).
At some point, the city itself will need to come up with a clear policy regarding the use of solar panels vs. trees for given situations. While either can be used in parking lots, trees (unlike solar panels) require soil and space to survive. As such, solar panels are suitable for a wider variety of locations (such as rooftops), while trees are not.
Until/unless the city comes up with a clear policy (supported by the tree commission), I would encourage the tree commission to not be distracted by an "either/or" choice, and simply focus its efforts on recommendations regarding trees and the benefits they provide.
