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.

COA#2015-0702 Approved. 2. 341 West North Shore COA#2015-0706B West North Shore No representation STAFF REPORT CONCERNING APPLICATION FOR A CERTIFICATE OF APPROPRIATENESS Date: 7 July 2015 Application Number: 2015-0706B Property Location: 341 West North Shore Drive Architectural Style/Date/ Traditional Ranch/1949 Property Owner: Patty and Dennis Gafvert Landmark or District Designation: West North Shore LHD Rating: Notable DESCRIPTION OF STRUCTURE/ SITE: The McLean House was built in 1949 and replaced a house that was demolished in 1939. The ranch house is one storey on a "rectangular plan with appendages". The exterior walls are random ashlar limestone. The roofline is a low hip with slate shingles. The entrance has a low shed roof. The windows are non-operable, fixed vertical divided light. ALTERATIONS: The windows are not original to the house as the survey card notes 10 pane casement windows. There are no COAs in this file. APPLICATION ITEMS: See attached description and drawings. Front Porch Roof. A new Hip Roof is proposed to replace an existing shed roof over the present entrance. The existing Shed Roof is not consistent with this period style California Ranch. The shed roof entry is very low and unusual in that the rest of the house is a hip style roof. The concrete stoop, limestone pier and metal railing will remain. A small amount of matching additional stone will be installed on top of the stone pier at the west side to support the roof. The steel column at the east side would be replaced with a taller steel column as needed. The roof material is slate and will be salvaged as part of the proposed new roof. Additional matching slate of similar specifications (size and color) will be installed to complete the new entry roof. A new full light entrance door is proposed to replace the raised panel door. Window Replacement: The existing non -original fixed sash windows are a replacement of the original operable casement windows. The proposed plans show new operable casement windows as per the proposed south elevation view. These will be custom fit to the existing masonry openings. This house was classified as "insignificant' in the survey of the historic district. A specification of the proposed windows is attached. New Garage: The North elevation view shows a proposed 2 stall garage off of the alley to the north of the existing garage. The existing attached garage will be converted to a master suite. The proposed garage roof will be a hip roof of similar slope to the existing in asphalt shingle. The overhang and fascia will be similar to the existing house in dimension and scale. The proposed siding will be painted horizontal cement fiber board with a 7" reveal, of compatible color to the existing limestone. North Entrance: A small entrance is proposed off of the north patio. The roof is proposed as a hip roof compatible with the existing house. DESCRIPTION OF PROPOSED PROJECT: Kil Architecture is proposing to re -configure the front porch entrance from a low shed roof to a taller hip roof. The new porch will use the same materials original to the house. The raised panel door will be replaced with a full light entrance door. The current fixed non-operable windows will be replaced with single light operable casements custom fabricated to fit the original openings. The new garage will be situated at the rear of the house off of the alley. It will have a hip roof covered in asphalt shingles that will compliment the slate roof of the house as well as the cement board
