2007: $2.05 billion

2006: $1.78 billion

2005: $894 million

2004: $772 million

2003: $640 million

If that doesn't do it for you, here's a lovely chart:

The highest assessed property? That would be the office building at 1100 New Jersey Ave., assessed at $128 million; the highest value for a single unimproved lot is (as always) the Consolidated Rail (CSX) land north of I Street, south of the Freeway (and under it, too): the 463,000 sq ft lot is assessed at just under $86 million (although keep in mind that some locations where development is pending--like, say, the stadium--are still seen in land records as many small lots rather than a single large one).

UPDATE: Should have just done this when originally writing this post--the combined assessed value of the 63 individual lots that make up the stadium site is (deep breath) $180 million, compared to $32.8 million in 2004. (And an additional update, the overall Hood numbers above were tweaked slightly--I guess I missed a couple lots when I first ran this, but the ratios and overall feel is still the same.)
