Map #5 shows the existing physical footprint of the tarpits in dark red, the approved tarpits in red, the tarpit applications in light red and pink combined with the forecast tarpit expansion to 2030 in light pink. This forecast was prepared by industry and the Alberta Energy and Utilities Board in 2001 and is now somewhat out of date. The forecast does not completely overlap with the larger areas that have actually been approved or applied for since 2001. The combined (cumulative) physical footprint of all the existing, approved, proposed, and forecast tarpits would be about 1,505.8 square km in the year 2030 or almost three times the current built-up (urbanized) area of the City of Calgary.
