Fig. 10. Development in the Lower Blue Planning Basin in 1999. For each parcel (not shown) in the private land (shown in pink), the number of units in each parcel is portrayed by randomly placing one point or dot per unit inside the parcel polygon. Each dot represents one housing unit, such as a condominium or single-family residence. For small parcels (e.g., near Silverthorne) the dots coalesce, so very densely settled areas will have many dots stacked on top of one another.
