I calculate small acreages of areas in Sacramento, no larger than about 2 acres at a time. I need an accurate projection to measure by the T as I don't always have access to groundtruthing.

If you only need accuracy in measuring the acreage/area, then an equal area projection should be sufficient as it preserves the area of polygons.

Alternatively, if your study area is relative small, you can consider using State Plane Coordinate System for California (Zone 2 for Sacramento).
