Within 3 miles of the Grand Pkwy.’s completed sections, more than 50,000 acres of development have sprung up in the past 5 years; they’re indicated by the pink patchwork in the map above, put out by Houston’s planning department. In following the highway, construction activity passes through 5 watersheds — Spring Creek, Cypress Creek, Addicks, Barker, and Brays Bayou — that aren’t seeing nearly as much concentrated development in non-roadside areas.
In order to plot out development across all of Harris County between 2013 and 2018, the map takes into account activity concerning “platting and general plans” over those years. That means the highlighted sections include parcels on which developers requested changes (for example, to merge adjacent properties or gain permission to build new types of structures), that often precede building.
