Thousands of people are out of their homes after Harvey dropped more than 9 trillion gallons of water over the Houston area.
The rain, which fell for four days, devastated Houston and its surrounding cities, flooding homes, destroying businesses and damaging schools.
The total amount of damage has yet to be calculated, but Hurricane Harvey is estimated to have caused upward of $40 billion in damage.
As floodwaters recede, several school districts will likely uncover just how much damage area schools have sustained.

Katy Independent School District campuses were hard hit by flooding.
Klein Independent School District said that majority of its schools sustained minimal damage with the exception of Lemm Elementary, which took on a “substantial amount of water from flooding.” The district said the damage is still being assessed.
Klein ISD is trying its best welcome Lemm Elementary school students into the new Klein Cain High School before the first day back to school Thursday.
All other Klein campuses start Wednesday.
Some parents said they need more time to prepare and want to extend the start of school at least another week.
The push to delay the start of school prompted parents in the district to start a petition that is nearly 4,000 signatures strong.
"if you're in a situation where you can't make it to school, don't worry about it, you take care of the situation you have at hand and whenever you are ready to make the transition, we're ready to welcome your student back,” Klein ISD Superintendent Brett Champion said.
Meanwhile, Kingwood High School in Humble Independent School District was severely damaged.
The board voted on Tuesday to combine students from Kingwood and Summer Creek High Schools. Students will be split into half-days, which means they'll have longer class times.

The district said the arrangement meets TEA standards despite the fact that students will be in class less.
Some parents in the Kingwood area are scrambling to get petitions signed. One parent said half-days at school will greatly impact special education and ESL students who may need the full day.
