SUPPLEMENTARY INFORMATION:

Background

The existing ATCT at the St. Louis Downtown Airport was built in 1973 and soon after was expanded by the addition of a mobile office trailer to house administrative personnel. The current tower stands approximately 52 feet in height with a controller's eye height of approximately 41 feet. Continual visibility problems, due to existing trees in an adjacent residential development, impeded the controller's line of sight for airfield movement areas and runway approaches. The visibility problem, due to trees obscuring significant portions of two runway ends, 4 and 30L, is ongoing and worsening. The proposed ATCT, with a total elevation of 138′ Above Ground Level (AGL) and a controller eye height of 116′ 4″ AGL would significantly improve visual capabilities.

Air traffic controller equipment in the existing tower has not been significantly upgraded since the ATCT was constructed in 1973, although there has been nearly a 50 percent increase in airport operations over the past 30 years. In the nearly 1970s, when the existing ATCT was constructed, annual aircraft operations recorded during operating hours of 7 a.m. to 9 p.m. totaled approximately 115,000. In 2001, the total number of operations recorded between the 7 a.m. to 9 p.m. timeframe was nearly 170,000. The proposed ATCT would allow for modernized equipment, enhancing the level of safety for the current number of aircraft operations at the St. Louis Downtown Airport.
