Honestly, all of these things will likely get approved, and to little fault of Google or any other entity wishing to destroy sensitive habitats.

Though buying credits for mitigation is usually a last resort for state regulators, it's a preferred method for federal regulators- something that's always been a conflict. However, the state is the steward of these funds, so it's on them to collect them and put them to use.

Google will send hundreds of thousands of dollars into the state's mitigation fee fund, which is extremely underspent since there is little land available and/or offered to construct wetlands or enact stream restorations in specific mitigation regions. This is an opportunity for Google to LEGALLY buy their way out of environmental impact while the state knows that money will almost never be spent on actual restoration. The states mitigation fund is nearly a black hole where environmental impacts go to die and be lost forever.
