@bkeegan @boulderreportinglab Here's historical imagery from 1985 from Google Earth. The "old" city is easily visible along the railroad/US-70 corridor, plus the suburban-like growth to the north. The major housing growth from 1975-2000 was all along I-40 and 15-501 (Hope Valley Farms, Woodcroft, near RTP) During this time, city leaders were literally begging developers to build more in the old city center, but it didn't happen.
