crumlish and crumlish architects, Inc. 0 October 1, 1996 Historic Preservation Commission of St. Joseph County County -City Building South Bend, IN RE: Replacement of Sidewalk at 1055 Riverside Dr., South Bend The existing tile sidewalk leading from the house to the public sidewalk is in a serious state of disrepair and needs to be replaced. In our opinion the tile sidewalk is not original to the property since it appears to have been patched and repaired numerous times. [See attached photos] The home dates from 1930 and we doubt that any tile sidewalk could have remained in place for the past 66 years if it were originally installed with tiles set in mortar. Current, and historic methods do not include installation of any masonry unit in a mortar setting when installed in exterior applications in areas subject to freezing. We believe that if a masonry sidewalk existed originally, it would have been set in sand without mortared joints. The current tile sidewalk is most likely a replacement, and should never have been laid in mortar. Any similar new tile installation is bound to fail again in a short time. We propose to replace the entire curving tile sidewalk and existing concrete subbase from the first step adjacent to the house to the street -side concrete walk. We propose using interlocking, sand -set concrete unit pavers colored to match traditional clay -brick pavers as close as possible. A new concrete paver edge would be installed with "Holland Stone" concrete pavers to replace the current clay -brick edgers that were set in mortar. The new concrete pavers will be set on a new subbase of compacted processed gravel. The new interlocking concrete pavers are a patented brand from Unilock masonry called "Classico" and have slightly rounded sides to allow gently curving layouts without necessitating cutting brick or odd -size joints. [See attached literature] The units will weave together to reproduce the "serpentine" layout of the existing walk, both in radius, width and length. The two existing, low, brick walls at the steps near the street will be retained. New "Pisa Stone" natural colored concrete pavers units will be installed for stair treads since they are slightly larger than the paver units and designed for use in stair tread applications. [See attached literature] A concealed flexible PVC plastic edging will be used to secure the pavers and edgers in place along the curving edges. The plastic edging is covered by the sod and leaves the Holland Stone edgers to appear as the visible edge of the new walk. [See attached literature] We believe the new sidewalk will be harmonious to the existing home and not detract from the historic character of the home or the neighborhood.
