City of South Bend and St. Joseph County Historic Preservation Guidelines 171 District Addendums: Leeper Park Local Historic District 6 . Paint removal should be considered only where there is a paint surface deterioration and as part of an overall maintenance appropriate protective coatings . Coatings such as paints help protect the wood from moisture and ultraviolet light and stripping the wood bare will expose the surface to the effects of weathering. 7 . Damage or deteriorated paint should be removed to the next sound layer using the mildest method possible . 8 . Propane or butane torches, sandblasting, water blasting, or other abrasive cleaning and/or paint removal methods shall not be permitted . Doing so changes the visual quality of the wood and accelerates deterioration . 9 . Repainting should be based on paint serration studies . If an adequate record does not exist repainting shall be done with the colors that are appropriate to the style and period of the building . D . Architectural Metals (Cast Iron, Steel, Pressed Tin, Copper, Aluminum, and Zinc) 1 . All metal materials, features, details and ornamentation of the buildings in the park shall be preserved . This also includes all met- al parts of all fountains, monuments, memorials, plaques, street lights, drinking fountains, etc . 2 . Original or later contributing metal materials, features, details, and ornamentation shall be retained and, if necessary repaired by patching, splicing or reinforcing the metal using recognized preservation methods . 3 . Deteriorated or missing metal materials, features, details and ornamentation shall be replaced with material and elements which match the original in material, color, texture, size, shape, profile and detail of installation. 4 . When replacement of materials or elements is necessary, it should be based on physical evidence or documentary evidence . 5 . If using the same material is not technically or economically feasible then compatible substitute materials may be considered . 6 . Cleaning of metal elements either to remove corrosion or deteriorated paint shall use the mildest method possible . 7 . Abrasive cleaning methods, such as low pressure dry grit blasting, may be allowed as long as it does not abrade or damage the surface . 8 . A test patch of the cleaning method(s) shall be reviewed and approved on site by staff of the Historic Preservation Commission of South Bend and St . Joseph County . Test patches should always be carried out well in advance of cleaning (including exposure to all seasons if possible) . 9 . Cleaning to remove corrosion and paint removal should be considered only where there is deterioration and as part of an overall maintenance program which involved repainting or applying other appropriate protective coatings . Paint or other coatings help retard the corrosion rate of the metal . Leaving the metal base will expose the surface to accelerated corrosion . 10 . Repainting should be based on paint seriation studies . If an adequate record does not exist repainting shall be done with colors that are appropriate to the style and period of the building . The Landscapes- Specific Standard and Criteria was financed in part with funds from the National Park Service, U.S. Department of the Interior, through the Massachusetts Historical Commission, Secretary of State, Michael Joseph Connolly, Chairman, and adopted for use by the Historic Preservation Commission of South Bend and St . Joseph County, Indiana, by permission of the Environment Department, City of Boston, Massachusetts, by Michael A. Cannizzo, Staff Architect, 1996. Return to the Table of ContentsDRAFT
