13 2.0. ARCHITECTURAL –EXTERIOR A. Walls & Chimneys With the exception of several large storefront windows, the majority of the exterior façade of the library is masonry. Due to the various renovations and expansions of the library, there are visible breaks in mortar joints where old/new brick meet or where openings (windows, doors) were present in the past. One of the biggest concerns for the masonry of the building is the lack of/improper placement of weeps to allow for air flow to assist in drying out the brick after rain events. In some locations, weeps are not present or may be covered by the dirt or mulch of the landscaping. There are some openings that appear to be weeps but may in fact be missing mortar that would permit insects and other pests to enter the building. While a portion of the building was recently tuckpointed, a majority of the building still remains untouched and some areas indicate they are in need of repair. At the front entrance, the stone columns/pillars are showing cracking which may indicate water infiltration beginning at the stone cap. Cracking is present at other locations around the building, including at the top of several parapets along the north façade and at deteriorating lintels above window/door openings where the lintels expand as they rust, causing mortar failure and brick cracking. As mentioned in the Site section, dark colored mulch and dirt have left unsightly staining on the building’s exterior. The chimney is in fair condition, however there is visual staining where vents are installed. The chimney also has a number of electrical components attached to it. The southern elevation’s aluminum fascia and soffit panels are deteriorated and in need of replacement.
