The Eye Came Through Humacao: Why UPR's Hardest-Hit Campus Held Classes in Tents for Months

PRhurricaneemergency notificationmedium confidence
Confirmed Threat

Hurricane Maria made its Puerto Rico landfall near Yabucoa on September 20, 2017, tracking directly through Humacao and leaving the campus of the University of Puerto Rico at Humacao as the most severely damaged in the UPR system. The campus library suffered catastrophic mold infestation and a destroyed roof; damages at Humacao alone were calculated at more than $35 million. The campus did not reopen until October 30, 2017, and held classes in outdoor tents because mold and lack of air conditioning made interior classrooms unusable.

[The University of Puerto Rico at Humacao announced suspension of all academic and administrative activities as Hurricane Maria, a Category 5 storm with sustained winds exceeding 175 mph, approached Puerto Rico on a direct track toward the eastern half of the island. With the storm expected to make landfall near Humacao, campus buildings were secured and all personnel were directed to evacuate to safe locations. Communications via SMS and email were expected to degrade as Maria approached.]

Humacao sits on Puerto Rico's eastern coast and was directly in the path of Maria's eyewall at landfall near Yabucoa on September 20, 2017; the campus sustained the most severe damage of any UPR facility
Pre-storm alerts from all UPR campuses were communicated via email and the upr.edu portal; SMS alerts degraded as cellular towers failed under Maria's approach

[University of Puerto Rico at Humacao remained closed as administrators assessed catastrophic storm damage. The campus library suffered a destroyed roof, extensive mold infestation throughout its collections of books, periodicals, and archival materials, and the loss of nearly all furniture and computers. Chemistry and biology lab air conditioning and fume hood mounts were torn off by 250-kilometer-per-hour winds. With the island-wide power grid destroyed, no electricity, internet, or cellular service was available; all communications occurred via battery-powered radio and in-person administrator visits to campus buildings.]

The UPR Humacao library was described by university officials and visiting library professionals as the most severely mold-damaged academic library on the island; mold spread throughout the entire environment within days without air conditioning
More than 25 inches of rain fell across Puerto Rico during Maria; at Humacao, which experienced the full eyewall passage, wind-driven rain penetrated sealed doorways
UPR Humacao's damages were calculated at more than $35 million -- the highest of any individual UPR campus after Maria

[The University of Puerto Rico at Humacao reopened for academic operations on October 30, 2017, six weeks after Hurricane Maria. Because mold contamination and lack of air conditioning made most interior classrooms uninhabitable, courses were held in outdoor tents erected on campus grounds. The university library remained closed pending mold remediation and reconstruction. Campus electricity was not expected to be restored for months. Students attended classes without functioning restrooms, air conditioning, or reliable water in many buildings. The university requested that all faculty and students return despite these conditions to preserve the academic semester.]

October 30, 2017 is the confirmed reopening date for UPR Humacao after Maria; multiple news sources report the tent-classroom arrangement as the defining feature of the post-Maria semester
The campus did not receive electricity until January 2018 -- approximately four months after Maria's landfall
Many Humacao students chose not to return, instead joining the mass emigration of Puerto Ricans to the US mainland following the storm; enrollment declined significantly in subsequent semesters
Context

Background

The University of Puerto Rico at Humacao sits on Puerto Rico's eastern coast, approximately 45 miles southeast of San Juan, and was the UPR campus most directly in the path of Hurricane Maria's eyewall at landfall near Yabucoa on September 20, 2017. The storm struck with sustained winds of approximately 155 mph and catastrophic storm surge. Campus damages were calculated at more than $35 million, the highest among UPR's eleven campuses, with the university system's total damage estimated at $133 million. The campus library was the most severely affected building: without electricity or air conditioning for three weeks, mold colonized the entire structure, destroying books, periodicals, archival collections, furniture, and computers. American library professionals flew in to assist with emergency triage. Chemistry lab fume hoods and air conditioning mounts were ripped off by 250-km/h winds and remained nonfunctional as the new semester began. With island-wide telecommunications and electricity destroyed, the university could not issue any SMS or email alerts in the days following landfall; administrators walked building to building to assess structural integrity. The campus reopened on October 30, 2017, with outdoor tents substituting for damaged interior classrooms, and without reliable electricity or water. Campus electricity was not restored until January 2018, four months after Maria. FEMA subsequently obligated tens of millions of dollars for UPR Humacao repairs, including a major allocation for library reconstruction and mold remediation. The case is notable as the most physically severe storm impact on any UPR campus and as a vivid illustration of the cascading effects -- mold, enrollment loss, multi-month power outages -- that followed the most destructive hurricane to strike Puerto Rico in a century.
Analysis

Key Findings

UPR Humacao sustained more than $35 million in damages from Maria -- the highest of any individual UPR campus -- because the eyewall passed directly over the eastern coast where the campus is located
The campus library suffered catastrophic mold infestation within days of the storm; the entire interior environment was contaminated due to the loss of electricity and air conditioning
The campus reopened on October 30, 2017 -- six weeks after landfall -- with classes held in outdoor tents because mold made interior classrooms unusable
Campus electricity was not restored until January 2018, approximately four months after Hurricane Maria
The experience accelerated student emigration from Puerto Rico to the US mainland; Humacao's enrollment declined significantly in the semesters following the storm
Outcome
Campus reopened on October 30, 2017, six weeks after Maria. Classes were held in outdoor tents for months because mold contamination made most interior spaces uninhabitable. The library -- the building most severely affected -- required major reconstruction and mold remediation. Electricity was not restored until January 2018. Enrollment declined significantly as students left Puerto Rico. FEMA subsequently funded repairs totaling tens of millions of dollars.
