HISTORICAL BACKGROUND: Information provided by historian Bridget Bacon The house was built in 1932 as a single family residence. There were 3 primary families who owned this residence from 1932 to 1999: John and Katie Porta, Pasqual and Loretta Jacoe, and Percy and Carolyn Conarroe. The current owner purchased the property in 1999. LANDMARK APPROVAL: Louisville City Council approved the landmark application for 1131 Jefferson Avenue, by a 7-0 vote, on September 21, 2010. PREVIOUS GRANTS: Incentive Grant - $1,000 (signing bonus) Incentive Grant - $5,000 (routine maintenance, painting) Restoration Grant - $2,719 (Site Work) Restoration Grant - $9,084 (Carport restructure, Sump Pump) Historic Structure Assessment - $2,200 (Technical Assistance Memo and Drawings) REQUEST: The applicant, Janice Hoffman, is requesting approval of a Preservation and Restoration Grant to allow for the existing roof to be restructured because it is undersized. The HPC/Council approved historic structure assessment (HSA) determined the existing roofing structure is substandard and must be retrofitted. Because the structure is a landmark, the HSA recommends retaining as many of the existing materials as possible. The roofing shingles, however, are not historic and may be removed. The following excerpt from the Technical Assistance memo, dated prepared by JVA April 6, 2011, states: “Our analysis indicates that the existing roof framing over the main portion of the house is severely overstressed. The rafters span approximately 17.5 feet from the eave to the ridge, far exceeding their capability. Supporting only the ceiling, the ceiling joists are capable of spanning from the exterior bearing walls to the interior bearing wall. But, the joists are overstressed when loaded by the intermediate line of support. Similarly over the Porch, the rafters have calculated overstresses exceeding Code allowed limits. “Recommendations: “Over the main portion of the house, the roof framing should be strengthened. The existing framing has significant calculated overstresses, localized areas of failure, and localized areas of excessive deflections. As such, the framing requires repair in order to be in compliance with the Code. “The design of such repairs is beyond the scope of this Memo. However, the following recommendations should be considered when determining the next steps: 1. Remove the intermediate lines of support in the attic in order to unload the ceiling joists and eliminate any further cracking in the ceiling finishes. 2. Support the rafter ends at the ridge. This would most economically be accomplished by constructing a wood stud cripple wall in the attic from the ridge 2
