Insulating Silver Beach.
Silver Beach wraps around the north end of Lake Whatcom, and being right on the lake makes ground and crawlspace moisture the whole story here. The high water table and the damp lakeside ground mean crawlspaces stay wet, sweat in the warm months, and grow mold in the framing if they're left vented and bare. Cold floors are common, but the bigger issue under a lot of these homes is moisture sitting in the crawlspace year-round.
So the routine work in Silver Beach is crawlspace encapsulation and vapor barriers, sealing the space against the lake's ground moisture, plus floor insulation to warm up the cold floors. For the wettest crawlspaces we seal the floor and walls, close off the vents, and add a dehumidifier, which turns a sweating crawlspace into a dry one. We always handle the moisture before we insulate the floor here, because insulating over wet ground just leads to wet, falling batts.

Moisture & prep considerations
Like everywhere in Bellingham, we air-seal and get the moisture under control before we insulate. In Silver Beach that means paying close attention to lake whatcom ground moisture, then insulating to current WA energy code.
