The Historic Preservation Commission of South Bend and St. Joseph County recommend that work proposed to the materials outlined in
<br />Sections B, C, and D be executed with the guidance of a professional building material conservator.
<br />1. Removal of the speakers atop Pump House Number 3 is encouraged.
<br />
<br />B. Masonry (Brick, Stone, Terra Cotta, Concrete, Stucco, and Mortar)
<br />1. [intentionally left blank]
<br />2. Original or later contributing masonry materials, feature, details, surfaces and ornamentation shall be retained and, if necessary,
<br />repaired by patching, piecing-in, or consolidating the masonry using recognize preservation methods.
<br />3. Deteriorated or missing masonry materials, features, details, surfaces and ornamentation shall be replaced with material and
<br />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 or documentary evidence.
<br />5. If using the same material is not technically or economically feasible, then compatible substitute materials may be considered.
<br />6. Original mortar shall be retained.
<br />7. Deteriorating mortar shall be carefully removed by hand-raking the joints.
<br />8. Use of mechanical saws and hammers shall not be allowed.
<br />9. Repointing mortar shall duplicate the original mortar in strength, composition, color, texture, joint size, joint profile and method of application.
<br />10. Sample panels of raking the joints and repointing shall be reviewed and approved by the staff of the Historic Preservation
<br />Commission of South Bend and St. Joseph County.
<br />11. Cleaning of masonry is discouraged and should be performed only when necessary to halt determination.
<br />12. If the building is to be cleaned, the mildest method possible shall be used.
<br />13. 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
<br />seasons if possible.)
<br />14. Sandblasting (wet or dry), wire brushing, or similar abrasive cleaning methods shall not be permitted. Doing so changes the visual
<br />quality of the material and accelerates deterioration.
<br />15. Waterproofing or water repellant are strongly discouraged. These treatments are generally not effective in preserving masonry and
<br />can cause permanent damage. The Commission does recognize that in extraordinary circumstances their use may be required to solve a specific problem. Samples of any proposed treatment shall be reviewed by the Commission before application.
<br />16. In general, painting masonry surfaces shall not be allowed. Painting masonry surfaces will be considered only when there is
<br />documentary evidence that this treatment was used at some point in the history of the property.
<br />C. Wood
<br />1. [intentionally left blank]
<br />2. Original or later contributing wood surfaces, features, details and ornamentation shall be retained and, if necessary, repaired by patching, piecing-in, consolidating or reinforcing the wood using recognized preservation methods.
<br />3. Deteriorated or missing wood surfaces, features, details and ornamentation shall be replaced with material and elements which
<br />match the original in material, color, texture, size, shape, profile and detail of installation.
<br />4. When replacement of materials or elements is necessary, it should be based on physical or documentary evidence.
<br />5. If using the same materials or elements is necessary, it should be based on physical or documentary evidence.
<br />6. Cleaning of wooden elements shall use the mildest method possible. 7. Paint removal should be considered only where there is a paint surface deterioration and as part of an overall maintenance
<br />appropriate protective coatings. Coatings such as paints help protect the wood from moisture and ultraviolet light and stripping the
<br />wood bare will expose the surface to the effects of weathering.
<br />8. Damage or deteriorated paint should be removed to the next sound layer using the mildest method possible.
<br />9. 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. 10. Repainting should be based on paint serration studies. If an adequate record does not exist repainting shall be done with the colors
<br />that are appropriate to the style and period of the building.
<br />D. Architectural Metals (Cast Iron, Steel, Pressed Tin, Copper, Aluminum, and Zinc)
<br />1. All metal materials, features, details and ornamentation of the buildings in the park shall be preserved. This also includes all metal
<br />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
<br />patching, splicing or reinforcing the metal using recognized preservation methods.
<br />3. Deteriorated or missing metal materials, features, details and ornamentation shall be replaced with material and elements which
<br />match the original in material, color, texture, size, shape, profile and detail of installation.
<br />4. When replacement of materials or elements is necessary, it should be based on physical evidence or documentary evidence.
<br />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
<br />surface.
