Facility Needs Summary

1. Needs Identified in Prior Assessments
   1. Athletics Facility Master Plan
   2. Differed Maintenance Schedule
2. Site Development
   1. Parking, Drop-off, Service & Delivery
       1. Service is accessed through Drop-Off/Pick-UP Lane. Trucks have to back into the service lane causing issues with vehicles entering drop off lane.
   2. Site Security & Access Control

3. Facilities
   1. Building Envelope
       1. Classrooms in 2-story are slightly undersized, making social-distancing difficult in those rooms @32 students.
       2. All portables show signs of settling/sinking. Only portable not sinking is Speech CR, but that unit leaks from the roof.
       3. Roofing has been replaced. Leaks are frequent occurrences. CR 9 and RR currently have leaks.
       4. 2-story classroom building has issues with Birds getting into overhang structure and inside buildings. Deck closure panels are missing in some locations allowing birds access to interior spaces.
   2. Building Systems & Equipment
       1. Air door fan over door at MPR is mounted to window wall system. Window wall system should be replaced. Window is not designed for the fan attachment. Vibration from fan is deteriorating the wall panels.
