Prohibited Wood siding shall not be resurfaced with new materials that is inappropriate or was unavailable when the building was constructed, such as artificial stone, brick veneer, asbestos or asphalt shingles. Sandblasting or the use of harsh detergents shall not be used on masonry including brick, stucco, limestone, flagstone and sandstone. This method of cleaning erodes the surface material and accelerates deterioration. Repointing shall not be done with a mortar of high Portland cement content which can often create a bond that is stronger than the building material. Usage of Portland cement can cause deterioration as a result of the differing coefficient of expansion and porosity of the historic masonry unit and the mortar. This most often results in serious damage to adjacent brick. Unpainted masonry surfaces shall not be painted unless they had been painted originally. Paint shall not be removed from masonry surfaces by any means that damage the surface. Not Recommended Waterproof or water repellant coatings or surface consolidation treatments should not be used on masonry surfaces unless required to solve a specific problem that has been studied and identified. Coatings are frequently unnecessary and expensive and can accelerate deterioration of the masonry. Mortar joints, which do not need repointing, should not be repointed. Wood siding should not be power washed. C. WINDOWS AND DOORS Window and door frames are in most cases wood and vary depending upon the style of the home. Many are double -hung windows with wood trim and sills. Brick structures have stone sills and brick lintels. In some cases where aluminum siding has been applied, the window and door trim has been covered. About half of the structures in the district have aluminum storm windows; the other half have wood storm windows. Required Original windows and doors shall be retained including sashes, lintels, sills, shutters, decorative glass, pediments, hoods and hardware. When deteriorated beyond repair, they shall be replaced with units and trim resembling the original. Recommended Wood storm windows and doors painted or finished to match the original should be used but should not damage existing frames. If new sashes or doors are installed, the existing or original materials, design and hardware should be used. When metal storm doors are used, they should be painted, anodized or coated to match the existing. When awnings are used, they should be of canvas material. D. ENTRANCES, PORCHES AND STEPS Most houses in the district have either an open or enclosed porch across the front. Most porches have either hip or gabled roofs or are covered by the main roof of the house. Required When deteriorated beyond repair, existing or original porches, stoops, patios and steps, including handrails, balusters, columns, brackets, tiles and roof decorations, shall be retained or replaced by replicas of the same design or by a design more in keeping with the historic period of the structure. Porches and additions reflecting later architectural styles, and which are important to the building's historical integrity shall be retained. Recommended When enclosing porches for heat conservation or for other reasons, it should be done in a manner that does not alter the architectural or historical character of the building. Not Recommended Original porch details should not be replaced with materials representing a different period or style from the original. SITE VISIT REPORT: N/A STAFF RECOMMENDATION; Staff recommends approval for: 1. The removal of the existing fiber siding to allow for the evaluation of the original siding beneath, 2. The installation of 35 metal storm windows (22 on front structure, 13 on rear structure), 3. The installation of new storm doors, 4. The removal of the metal awnings over the front windows and doors,
