Before the storm hit, Amber and Lenny Ambrose packed up their two young kids and small dog and drove to Amber's parent's house in Nederland, outside of Beaumont. The Ambrose's house in Candlelight Forest flooded during the Tax Day storm in 2016, and they didn't want a repeat of what happened then when they woke up the morning after the storm to soggy floors and confused kiddos. They made some important preparations and left town. Their flood insurance policy renewed Aug. 27, the night Harvey flooded their house. It was a good thing they didn't let their policy lapse, even though they could have. They were told in 2015 they were no longer required to carry it. Amber tells their story in the final episode of this Harvey series.

From episode 23, Nancy and Erin talk to Chronicle journalists Mike Morris (City Hall) and Mihir Zaveri (Harris County) about their reporting on floods and development after two major flooding events two years in a row. 

Residents of Canyon Gate say they were never told about the warning that said their neighborhood could be subject to severe flooding because it was built in a so-called flood pool behind Barker Reservoir. Investors who bought millions in bonds that financed the subdivision weren't told either. Houston Chronicle's James Drew talks to Nancy about his investigation into Canyon Gate and what was and wasn't disclosed.

Brandon Polson recounts his journey from helping his neighbors escape their flood-ravaged apartment complex to spending an evening with one of the biggest celebrities on the planet.

As Harvey's flood waters continued to rise in Braes Heights, Scott Davis, his wife and their two young daughters fled to a neighbor's place – a brand new house built five feet above grade. As Davis sees it, the safest place to ride out the hurricane was in a new house. As a home building consultant, he also addresses past Houston floods, how the market responded and how development may change in the future.
