Both asbestos and lead paint were found in building materials. • • 2018: The Mueller Team secured historic zoning designation from the City and an historical marker from the State. 2020: McCann Adams Studio developed design guidelines for the tower block to protect views of the Control Tower and coordinate proposed uses within the block. 3 | RMMA PIAC | 05-14-2024 Control Tower – Tower Base Plans Tower Access Challenges • The white base of the former Control Tower was originally surrounded by the airport terminal; it became exposed when the terminal was deconstructed. • In 2021, at the online community meeting, some attendees expressed a desire to treat the tower base. • In 2021, the Mueller Team met with city historic preservation staff who provided guidance that: Treatment of the actual tower base would not be in line with the historic designation, and If a treatment was to be provided it would need to be offset from the building so as not to affect the integrity of the structure. • The Mueller Team revisited the plans: The team followed staffs’ guidance to avoid directly treating the base or affixing screening to the base. The decision was made to honor the building as a landmark but soften the area around tower base with flexible seating areas and landscaping that will screen the view of the base over time. The plaza design does not interfere with future efforts to make the Control Tower interior accessible to the public. 1) 2) – – – 4 | RMMA PIAC | 05-14-2024 Control Tower – Current Repairs Tower Access Challenges Crews are currently making renovations to the former Control Tower to prevent deterioration and make it safer for future visitors to the plaza: • Abating asbestos and lead paint • Removing existing extraneous plumbing, mechanical and electrical • Securing elevator and addressing basement water infiltration Installing new electrical, including lighting • • Installing new roof • Replacing and installing new exterior panels • Applying a new coat of paint on the interior 5 | RMMA PIAC | 05-14-2024 Control Tower – Present Challenges to Public Access Tower Access Challenges Elevator that does not meet ADA requirements Proper evacuation of visitors in case of emergency Proper access to visitors in case of medical emergency Access for people with mobility challenges Views from the top • • • • • • • • • • Elevator does not reach top floor No second means of egress Occupancy limits Fire suppression Restrooms O&M (insurance, funding, staffing) 6 | RMMA PIAC | 05-14-2024 Plaza Plans – Previous Design Tower Access Challenges Dec 2021 View of tower from paseo, looking west Dec 2023 7 | RMMA PIAC | 05-14-2024 View of tower from paseo, looking west Plaza Plans – Current Design Tower Access Challenges 8 | RMMA PIAC | 05-14-2024 Plaza Plans – Current Design Tower Access Challenges Approaching the tower from the paseo 9 | RMMA PIAC | 05-14-2024 Plaza Plans – Current Design Tower Access Challenges Seating and shade provided within plaza at tower base 10 | RMMA PIAC | 05-14-2024 Plaza Plans – Current Design Tower Access Challenges Elevated pedestrian walkway and seating within plaza 11| RMMA PIAC | 05-14-2024 Plaza Plans – Current Design Tower Access Challenges Seating and shade provided within plaza at tower base 12 | RMMA PIAC | 05-14-2024 Plaza Plans – Current Design Tower Access Challenges Elevated pedestrian walkway overlook into plaza 13 | RMMA PIAC | 05-14-2024 Plaza Plans – Current Design Tower Access Challenges Bird’s-eye view into plaza 14 | RMMA PIAC | 05-14-2024 Anticipated Schedule Tower Access Challenges Apr 2024 May 2024 June 2024 Q4 2024 Q1 2025 Control Tower Repair Construction Begins Plaza Construction Begins Paseo Opens as Rivette Begins Move-ins Control Tower Repairs Complete Plaza, Paseo & Repairs Estimated Completion 15 | RMMA PIAC | 05-14-2024 Thank You | Questions & Answers Questions & Answers 16 | RMMA PIAC | 05-14-2024
