The Baltimore Demolition Protocol

Regardless of the difference in opinion about how smart mass demolition is in a City that plans its comeback through population growth, demolition is in itself a risky activity with a good number of inherent risks including contamination of air and neighboring sites. It is good then to know that Baltimore led the nation with what is known as the Baltimore Demolition Protocol. Or maybe not.
Lead poisoning leads to crippling mental and physical health effects.  Lead-based paint in older homes becomes a toxic dust storm when whole neighborhoods are demolished for new growth. Yet, nowhere in the United States were there any construction protocols minimizing health risks during building demolition. That is, until 2004 when the Annie E. Casey Foundation and Johns Hopkins University took East Baltimore, Maryland, resident concerns to heart and created a whole new rulebook. (Anne E. Casey website)

The matter came to a head when EBDI had begun mass demolition around Washington Street in what would later be known the phase 1 area of redevelopment, essentially the area just north of the Hopkins campus and Ashland Street. When the dust rose from the collapsing rowhouses of what was once the Middle East neighborhood the Save Middle East Action Coalition (SMEAC), already incensed by EBDI's elephant in the china store approach in the community and the ensuing displacement, jumped into action. Their complaints were numerous: There was only scant water spraying, neighbors kept their windows open during demolition work and kids were found wandering through the unprotected contaminated rubble. SMEAC forced a much more careful method of demolition that was the result of months of community meetings and collaboration between EBDI, Casey, Hopkins and SMEAC.

A Casey funded report in 2011 gained national attention by establishing the Baltimore Protocol. The protocol includes
  • fencing, 
  • community notification through documented signs, 
  • training of demolition supervisors, 
  • deconstruction of specific high lead items such as windows, doors, and stair railings prior to demolition, 
  • ample spraying during demolition and debris removal, 
  • careful street and sidewalk cleaning to remove residual dust, topsoil removal 
  • replacement of the yards of demolition lots, 
  • providing neighbors with HEPA vacuums and independent testing of the area after the demolition and cleaning is done. 
The city of Baltimore introduced a plan to revitalize East Baltimore and spurred new safety standards that may change the future of demolitions across the country. Before East Baltimore’s redevelopment, little research existed on the effect demolitions had on a neighborhood’s ambient air quality. A 2003 study analyzed lead dust and accumulation from sites near EBRI’s redevelopment site. Results showed that, following demolition, lead dust levels in the environment increased by as much as 40 times, and there was a 6-fold increase during debris removal. 
The EBDI demolition protocol proved to be so effective and associated costs so minimal that in 2007 the city of Baltimore revised its building code so that safety measures from the EBDI protocol are now a citywide standard. The state of Maryland is also considering adopting new legislative standards that would require similar safety measures be used throughout the state. (HUD user online)
Tests using the protocol showed that lead contamination was much lower ( a 33% increase over the baseline levels) than in cases where the protocol was not used (150 -400% increase over the baseline). At the time the City, Maryland Assembly and even HUD had indicated a desire to adopt these standards and making them mandatory.
Demolition of entire blocks, a trademark of project CORE

It is fairly astounding, then, to hear the HCD Commissioner in July 2017 at a CORE progress event respond to a question about the safety of the City demolition program. Michael Braverman stated that the City is "currently studying" the demolition protocol of the Maryland Stadium Authority (MSA) and intends to implement it "when the review is done".

Why weren't the Baltimore Standards of 2011 used in those past six years if they were supposedly part of the code as HUD reported? Why is MSA studying the matter anew? Why did an emergency demolition earlier this year still create not only a large plume of dust wafting over Fort Street in South Baltimore but was also done so incompetently that it destroyed a second building that had been slated to be be rehabilitated? Sometimes Baltimore is ahead and then slips back again.

  1. Stadium Authority via its construction managers has run construction on "21st Century Schools". Nobody in-house knows the rules, Minimal number of schools were in such bad condition that drastic lead-mitigation measures were needed. Older buildings were usually protected by CHAP. The 2011 standards were probably lost when HCD transferred lead responsibilities to Health Department, which mainly dealt with complaint-driven single family scattered sites. Couldn't say which department is currently responsible for lead, and fear a search of the City web site. Nobody knows what anyone else is doing.
