DALLAS-Once when referring to the uptown submarket in terms ofcommercial real estate, the demarcation linebetween it and Dallas' CBD was between Olive and Harwood Streets,directly north of the Woodall Rodgers Freeway. Butexperts tell GlobeSt.com the demarcation linebetween the uptown and downtown submarkets has moved south acrossWoodall Rodgers, which is impacting everything fromCRE rental rates to office buildingtransactions.

"Ross Avenue (approximately two blocks south of Woodall Rodgers)is considered the new border of Uptown," says CreightonStark, senior vice president of investment sales withColliers International's Dallas office. "Everything north of Ross today falls into the uptown market."

One potential catalyst, a major one, fueling this trend is a5.2-acre park currently under construction, known as theKlyde Warren Park, a deck park being built overWoodall Rodgers Freeway between Pearl and Saint Paul Streets. Oncethis park is completed in fall, 2012, it will provide a walkablelink, complete with performance venue and dog park, between theuptown and CBD submarkets, and could even blur the lines betweenthese two submarkets.
