Harris County Flood Control District (HCFCD) spending data on right-of-way acquisition and construction for the first half of 2022 shows that, once again, the San Jacinto watershed has been ignored. Thus, the largest watershed in the county received virtually no help in terms of flood-mitigation funding. Brays, where Precinct One Commissioner Rodney Ellis lives, received […]

Why Hurricanes Often Track Like Boomerangs

Some Still Deal with PTSD, Five Years after Harvey

Five years after Harvey, post traumatic stress disorder (PTSD) still haunts many of the victims. Readers have written me about how hard they find it to shake painful memories.
