Parkview Apartments – 4451 Forest Park Avenue, St. Louis, Missouri

Background

In January 2021, due to a severe cold snap, the fire suppression system ruptured and flooded Parkview Apartments from floors six through ground. Multiple apartment units, administrative offices, and mechanical rooms were affected after the release. Rapid assessment and mitigation were necessary to prevent mold growth, structural damage, and equipment loss. ENPAQ, LLC conducted a water mitigation assessment, hazardous material survey, and project oversight services for this incident.

Objective of Assessment

  • Determine the extent of water damage
  • Identify affected materials (porous vs. non-porous)
  • Evaluate risk of microbial growth
  • Recommend remediation strategy and drying plan
  • Conduct preconstruction hazardous material survey of affected areas

Assessment Methods

  • Moisture Mapping: Used FLIR infrared cameras and moisture meters to detect hidden moisture in walls, ceilings, and flooring.
  • Material Sampling: Collected wall and floor core samples in apartment units and commons spaces.
  • Relative Humidity Readings: Tracked ambient RH to determine vapor pressure differentials.
  • Containment Zones Identified: Established key zones based on contamination levels and material saturation.

Challenges

Extent of Damage: Soaked walls and ceilings; risk of mold and structural issues.
Urgency: Immediate response needed to mitigate further damage.
Coordination: Required coordination with restoration contractor and facility staff, and insurance adjusters.

Lessons Learned

Early Response Prevents Secondary Damage: Delays in water extraction led to mold growth, which increased remediation costs and health risks.
Staff Training Improves Response: Staff were unsure how to respond, delaying damage control. Post-event, a flood response training program was implemented.

Conclusion

The Parkview Apartments incident highlighted the importance of proactive infrastructure planning, routine maintenance, and emergency preparedness in water mitigation. By implementing the recommended actions and training programs, the facility is now better prepared for future events.
