Pleasanton Century House Assessment Report March 30, 2019 Page 4 2. The three wood stairs at the exterior (3 -sided) porch show many signs of deterioration, such as dry rot or termite damage. 3. At the main building exterior foundation walls there is a 1 -foot tall wood cripple wall that is not braced. In addition, there is no means for lateral shear to transfer through the cripple wall down to the masonry foundation wall. 4. At the two central main walls (on each side of the stairs), the foundation consists of an unbraced and non_anchored cripple wall sitting on top of an unreinforced brick continuous wall/footing. 5. At the small rear addition (west side), the existing foundation wall consists of an unbraced cripple wall that is not anchored to the concrete continuous footing. 6. At the exterior (3 -sided) porch many of the perimeter support post and footings show signs of deterioration. In addition; the support posts are not tied to the 4x8 perimeter support beams and are not tied to the footings. 7. At the crawl space below the floor, the interior 6x6 post that support 6x8 1 st floor beams, there is no tie at the top and bottom of the posts. 8. The existing lateral load resisting shearwalls consist of 1x6 horizontal exterior siding. There is no plywood for shear. 2nd Floor Level: 1. The main 4x6 post that support the porch roof do not have adequate connections to the beams above and below. Existing posts are only attached with toenails. 2. The 6x6 corner post that support the porch roof do not have adequate connections to the beams above and below. Existing posts are only attached with toenails 3. Where the porch roof attaches to the side of the main building walls, there is no tension tie to prevent the roof from pulling away from the building in a seismic event. 4. The plywood at the small porch roof (northwest corner) is severely deteriorated (see Photo 7). 5. There is an existing abandoned brick fireplace that is likely not seismically tied to the floor diaphragm (see Photo 12). Since there is no chimney, we believe this was removed during a previous remodel. Note: this fireplace extends down to the ground (into the crawl space), as such, if the building were to be relocated it would be necessary to completely remove the brick fireplace. 6. The existing lateral load resisting shearwalls consist of 1x6 horizontal exterior siding. There is no plywood for shear. Detailed recommendations are included in Attachment 3, but essentially comprise replacement of all deteriorated material, :insulation of new continuous footings and shear panels and adding appropriate connectors to insure a complete seismic system for the building. 28o Bettencourt Street, Sonoma, CA 95476 www jeffkatzarchitecWre.com
