  Depending on how "recent", many of these areas can be accessed through the USGS Seamless
webserver

  http://seamless.usgs.gov

  The USGS Urban Areas Hi-Res imagery project has very high-res (sometimes 1ft) color
imagery of many cities. Certainly Englewood, maybe Bellevue, not sure about Sugar Land.

  Also, the USDA NAIP program has imaged most of the US quite frequently (often once a
year), typically at 1m color. Some of this imagery is available through the USGS Seamless
site. Sometime you need to consult the USDA Lighthouse data server to access more years
and more products. These files are gigantic multi-gigabyte MrSID county mosaics.

  These data are all free of charge, but can be time-consuming to obtain. there are
commercial data sources that are easier, possibly more current or higher-resolution, but
quite a bit more expensive.

  I'd be happy to answer any questions about these privately.
