His name is Maurice Cox and he is coming to Detroit via New Orleans and Charlottesville, Virginia. According to this 2012 article in The Hook, Cox was long-time bike commuter and an apparent supporter of Complete Streets.
More of his background is available in this City of Detroit release.
That release also mentioned that Cox will focus on the neighborhoods:
With new businesses and residential developments already going strong in downtown and midtown, Mayor Duggan has charged Cox with focusing his energies on developing strategies to strengthen existing neighborhoods and reuse land in largely vacant areas of the city.
Mayor Duggan has expressed an interest in exploring new uses for large tracts of vacant city land, including green infrastructure to reduce storm water run-off and appropriate urban agriculture. He also has talked about creating more densely populated and walk able urban neighborhoods throughout the city that are sustainable unto themselves with a diversity of residents and small businesses.
Cox thanked Mayor Duggan for this opportunity and said he hopes to build from the uniqueness of Detroit while bringing new ideas that represent the best of what he’s seen and done elsewhere.
“Detroit has a once in a lifetime opportunity to re-imagine the American city, transforming an abundance of land into a valuable community asset. We can take advantage of Detroit’s many historic neighborhoods to create new urban housing anchored by revitalized commercial corridors, parks and greenways, all working together to enhance the quality of life in this city for everyone,” Cox said. “Detroit is well positioned to be the place where urban innovation and economic opportunity intersect, creating a new kind of sustainable city–one that is equitable, just and simply more beautiful.”
Those are his words but our underline. Yes, he mentioned greenways.
His appointment does require City Council approval, but so far he has ours.
