Commission backs tighter setback flexibility for tall structures with engineering safeguards
Loading...
Summary
The commission recommended Resolution 25-26 to amend MSB 17.67, allowing reduced minimum setbacks for telecommunications towers where engineering (e.g., 'breakpoint' design) demonstrates no risk to public safety. Staff cited past tower collapses and described engineering approaches to limit fall radius.
The Planning Commission recommended an amendment to MSB 17.67 (tall structures) to allow reduced minimum setback requirements for new telecommunications towers and other tall structures when applicants provide engineering demonstrating no risk to public health, safety and welfare.
Planning Director Alex Strong reviewed the code history, noting the existing ordinance generally requires setbacks equal to tower height unless a lesser setback is justified. Strong described engineering approaches — including engineered weak points or "breakpoint" technology — that can reduce fall risk by ensuring a tower would collapse on itself rather than fall onto neighboring property. He also noted instances of meteorological data towers that collapsed in windstorms, underscoring the need for careful engineering and maintenance.
Commissioners asked whether breakpoint technology could be mandated; staff said the code could require such technology but that flexibility exists to allow towers that pose no risk to nearby properties to qualify for a reduced setback. The chair opened and closed the public hearing with no speakers; Commissioner McCabe moved and Commissioner Scoggins seconded the motion to recommend Resolution 25-26, which passed by voice vote with no objections.
Next steps: the recommendation will be forwarded to the Borough Assembly, and any tower proposals will still require specific design review, permits and possible ongoing maintenance conditions.
