Information Provided by the Applicant Although information provided by the applicant is not applicable to the review criteria for demolition of 334 Atlantic Avenue, it has been reviewed here as related to the larger issue of historic resources, sea level rise, flooding, and climate change. The engineering report provided by the applicant notes the following: • "No structural analysis was performed on the building to determine the capacity of the structural systems." • "Building constructions and standards of the 1930s are considered deficient by today's standards. This applies to this structure and other structures built in the 1930s. This building does not comply with current building code." • "To bring this building into compliance, it must undergo level III alteration of the Florida Building Code 2020 (7th edition) for existing structures. This means that the building has to be strengthened to comply with the current Florida Building Code. Which means that the roof connection tie downs have to be implemented to strengthen the roof and lateral load structural systems have to be installed, such as shear walls. Wall openings such as doors and windows and the exterior CMU walls must be reinforced. All corners of the building would need concrete columns. Hence, the foundations also must be strengthened to resist such lateral loads." • "We noted the current building has some deficiencies that might [italicized added for emphasis] compromise the integrity of the structure in case of a hurricane or storm scenario." • Information is shared on the data from the results of the concrete core testing, but not analyzed to summarize the results. • Mitigation options are suggested: • "In order to raise the structure a complete foundation rehabilitation and redesign need to occur to sustain the jacking loads." • "Level III alteration would require demolition of the corners of the house to add corner columns." • "Floor ledgers (2nd floor) need to be installed to comply with current code and standards." • "Pursuant to FEMA, if the cost of the renovations exceeds 50% of the value of the structure without the land, the structure has to be elevated to meet current flood requirements. Therefore, raising the house up to needed elevations for compliance is not feasible, the whole structure would have to be upgraded for level III alteration required by Florida Building Code 2020 — 907.3 Existing structural elements carrying gravity loads and 907.4 Existing structural elements resisting lateral loads." In response to the engineering report and associated request letter: • Non-compliance with the Building Code is true of the majority of similarly situated historic structures. It is not a reason to de -designate a landmarked structure. • The report notes what is needed to bring building into compliance, but does not address cost or Building Code variances that may be an option.
