Anchorage Assembly to consider buying two wetland lots for under $30,000

Anchorage is looking to buy wetlands so it can keep building elsewhere. It's an arrangement most people never see, and two small marshy lots on the city's south side are the latest piece of it.

The Assembly votes July 7 on adding two parcels in the Laurel Acres Subdivision — about half an acre of Class B wetlands, home to patterned ground and migratory birds — to the city's conservation land bank.

The lots have no road, no utilities, and little value as buildable property, but they're valuable for a different reason: preserving them generates "wetland mitigation credits."

That's the mechanism worth understanding. Under federal rules, when development disturbs wetlands somewhere in Anchorage, that loss has to be offset by protecting wetlands elsewhere. The city banks those protected acres and cashes in the credits when a future project needs them — in effect, saving one marsh so a road or subdivision can be built over another

Anchorage has been assembling Laurel Acres this way for years and already owns more than 100 parcels there under conservation easements; these two extend that block, and the owner agreed to sell for less than the assessed value.

It's a small, cheap transaction — the city pegs the cost under $30,000 — but it's a window into how a growing city balances development against the wetlands it's required to protect.
