Again, whether you or I like it or not, it is going to happen in Sandy. There are a myriad of reasons for this happening, most of which have absolutely nothing to do with arrogance. Whether those of us on this forum agree or not, there are many who prefer to live in a suburb and commute five minutes to a close-in commercial center rather than downtown. The only arrogance IMO is assuming an attitude of 'my way or the highway'. I feel that as long as downtown Salt Lake continues on it's current path, there will continue to be an increasing amount of people who choose to live downtown. IMO, the mistake is not offering options. I in no way would be so presumptious as to think that my preferred way of living must apply to all people.
Regarding Downtown Salt Lake. Ten years ago, the sprawling area we now call the Gateway District was little more than brown earth. Ten years ago even the immediate area surrounding Temple Square was full of parking lots. Ten years from now much of what are now vacant lots in the western sector of downtown will be attractively developed. Downtown will continue to develop in an attractive and amazing pace. This will happen whether places such as Sandy and Lehi become business hubs or not.
Speaking of Seattle and Bellevue, Bellevue is almost a perfect illustration of Sandy and what it will probably become. Bellevue is little more than 7 miles from Seattle. Depending on I-90 traffic, typically less than a fifteen minute drive. It's recent boom and the impressive buildup of it's downtown is a strong indicator on a number of levels as to what is happening in many of America's fifty largest metros, particularly those which are experiencing dynamic growth, such as Salt Lake's MSA. A far better comparison than Bellevue and Provo, would be Tacoma and Provo. Tacoma, also a major part of Seattle Metro is approximately 30 miles from Seattle proper. That would be basically the same distance and perspective on many demographic and infrastructure levels as Provo and Salt Lake.
Before we know it, the Wasatch Front will reach 3 million people, then we will be on a path toward 4 million-plus. Metro Seattle now has 4 million-plus people. I'm sure as the Wasatch Metro grows to three and 4 million people, it will begin to strongly resemble Seattle's current cores, i.e. Seattle/Salt Lake City, Bellevue/Sandy, Provo/Tacoma.
Downtown Tacoma - 30 miles from Seattle Proper
Downtown Bellevue - 7 miles from Seattle Proper
