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.
<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 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
<br />application.
<br />10. Sample panels of raking the joints and repointing shall be reviewed and approved by the staff of the Historic Preservat ion
<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
<br />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 v isual
<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
<br />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
<br />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.
<br />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 lig ht 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
<br />permitted. Doing so changes the visual quality of the wood and accelerates deterioration.
<br />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.
<br />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.
<br />6. Cleaning of metal elements either to remove corrosion or deteriorated paint shall use the mildest method possible.
<br />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.
