CERTIFICATE OF APPROPRIATENESS Date: May 7, 2012 Application Number: 2012-0507E Property Location: 1097 Riverside Drive Architectural Style/Date/Architect or Builder: Foursquare/1906 Property Owner: Brian Exner Landmark or District Designation: Riverside Drive LRD Rating: Non -Contributing DESCRIPTION OF STRUCTURE/ SITE: This two storey frame house is set upon a concrete foundation and has a high hip roof. Siding is 3" clapboard on the second storey and 4" clapboards on the first. A gabled dormer is centered in the front over a set of 1/1 double hung windows. The full front porch has been restored and features columns, brick piers, and an off center gable feature with a sunburst detail leading up the stairs toward the front door. Front door is wood with a decorative light. ALTERATIONS: The aluminum replacement siding noted in the 2005 survey has been removed and the original wood siding repaired or replicated. The enclosed porch in the 2005 survey has been removed and the original front porch footprint and details were reproduced. APPLICATION ITEMS: Altering overhead door opening on existing garage. The garage will be straightened. Internal bracing will be screwed and glued to the studs on the inside walls in order to maintain the walls in a square and plumb condition. However, this will not be possible on the end of the garage with the overhead door. In order to adequately support this end of the garage, the wall to the left side of the overhead door will be extended approximately 2 feet, decreasing the width of the door opening from 12 feet to 10 feet. The new wall will be framed with 2 x 4 studs. Then, 5 / 8" plywood will be screwed and glued to the studs to provide structural rigidity, and new wooden Cove "Dutch Lap" siding will be installed over the sheathing. The siding to the right of the overhead door will also be removed and sheathing will be applied beneath. Usable siding will then be reinstalled and unusable siding will be replaced as necessary. DESCRIPTION OF PROPOSED PROJECT: Because the siding is nailed directly to the studs with no sheathing or internal bracing, the garage has developed a lean. This lean is most pronounced at the end with the overhead vehicle door. The lean was exacerbated by a previous owner who replaced the original door with a wider one. In doing so, it was necessary to remove a portion of the end wall of the garage. Based on the witness marks on the slab, the owner believes the original door was 8' wide. The garage leans approximately 4.5" over the height of the wall. STANDARDS AND GUIDELINES: II. EXISTING STRUCTURES A. BUILDING MATERIALS Original exterior wall materials in the district include limestone, flagstone, stucco, clapboard, wood shingles, sandstone and masonry block. In some instances, vinyl or aluminum siding has been applied over the original surface. Required Original exterior building materials shall be retained. Deterioration of wood materials shall be prevented through repair, cleaning and painting. The existing or original architectural detail around windows, porches, doors and eaves should be retained or replaced by replicas of the same design and materials when deteriorated beyond repair. Masonry including brick, limestone, flagstone, sandstone and stucco shall be cleaned only when necessary to halt deterioration or to remove stains, and shall be done with a method acceptable for the preservation of the surface: i.e. low pressure water and soft natural bristle brushes. When repairing stucco, stucco mixture compatible in composition, color and texture shall be used. Recommended Whenever possible, the original building materials should be restored. Metal or vinyl siding may be used when it is the only altemative to maintaining or replacing the original surface material. When used over wood surfaces, this siding should be the same size and style as the original wood. Every effort should be made to retain the original trim around windows, doors, cornices, gables, eaves and other architectural features. Ample ventilation must be afforded the structure when metal or vinyl siding has been installed in order to prevent increased deterioration of the structure from moisture and/or insects. Mortar joints should be repointed only when there is evidence of moisture problems or when sufficient mortar is missing to allow water to stand in the mortar joint. Existing mortar shall be duplicated in composition, color, texture, joint size, method of application and joint profile. It is emphasized that, prior to initiating any restoration or rehabilitation effort, the property owner should contact the Historic Preservation Commission of South Bend and St. Joseph County which is located in the County/City Building of South Bend. The Commission is an invaluable source of information about all facets of rehabilitation and restoration. Prohibited Wood siding shall not be resurfaced with new material which 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. Brick surfaces shall not be painted unless they had been painted originally. 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. This can cause deterioration as a result of the differing coefficient of expansion and the differing porosity of the material and the mortar which can result in serious damage to adjacent brick. Paint shall not be removed from masonry surfaces indiscriminately. Not Recommended Waterproof or water repellent 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. 7
