It wouldn’t feel right to let a week pass without another multimillion-dollar purchase by Denver-based Healthpeak in the Alewife area – and on Thursday came news of a $72 million transaction for 67 Smith Place.

Before a tree-cutting moratorium went into place in 2019, the pace of felled trees seemed to accelerate; while it’s not so simple for multimillion-dollar construction, developers, city councillors and Planning Board members are all trying to figure out how a lab- and office-space moratorium affects business as usual.

Rents were down 1.8 percent in December after a year in which Cambridge saw a 25.2 percent rise in prices and Somerville rose even more, according to some real estate industry analysts. Another local trend continued too: Life-sciences clusters spreading from Kendall Square.

An affordable-housing project that will overlook Danehy Park won praise from members of the Planning Board on Tuesday. One member called it a “poster child” for new Affordable Housing Overlay zoning that reduces the power of the board in refining projects before they’re built.

If the goal of eliminating single-family zoning in Cambridge is to right decades of racial injustice and inequity, the Planning Board was unconvinced Tuesday that the city was anywhere close to a way to achieve that.

Planning officials voiced serious misgivings last week around the specifics of the Affordable Housing Overlay, which so far underlies three projects making their way through Cambridge’s permitting process. But they acknowledged that they were forced mainly to watch with concern.

The Denver company Healthpeak spent another $41 million on Alewife-area property on Nov. 27, adding 125 Fawcett St. to the $391 million portfolio it’s built since August, according to documents filed Tuesday with the Middlesex Registry of Deeds.

The $900,000-per-unit cost of rebuilding Jefferson Park public housing stems partly from extraordinary factors such as bidding and wage requirements for public agencies, the large number of family-sized units, deteriorated utilities and hazardous materials at the site an analysis shows.

Tucked away in the wilds of Cambridge – near Alewife – lies what is essentially the local ninja training center. The building is due to be torn down to become lab space, though, and neither kung fu nor sword skills can hold off the bulldozers. A development moratorium might.

The idea of stopping office and lab space from being added in the Alewife area until city planning is in place passed the City Council in 7-0-2 vote Monday. But that moratorium needs its own process.
