The cost estimate does not include any repair to the existing Colusa sandstone on the extedor of the building. Portions of the building, particularly on the west side, have a significant amount of stone that is cracking or spawiing. All work done on the exterior of the building will have to meet the requirements of the Secretary of the Interior's "Standards for the Treatment of Histodc Properties." 4. Demolition of the Fiscal Annex. The Fiscal Annex, completed in 1939, is also part of the National Register of Histodc Places. This means that certain guidelines will have to be followed during demolition. Most of the intedor doors, marble wainscotting, and other removable fixtures will be removed pdor to demolition. A photographic survey of all of the important artifacts will also be done. There is nothing in the demolition plan that is prohibitively expensive or requires special permits. The items removed from the building can either be kept in Redwood City to be used in other historic buildings, or sold to a salvage yard that sells historic building materials. 5. Material to be used on Exterior Renovation of Buildina. The existing matedal on the building and the material removed when the portico was demolished is Colusa sandstone. This material is not readily available, although for a price it can be removed from the quarry. As part of the "Basis of Design," two other types of material were investigated: (1) GFRC (Glass Fiber Reinforced Concrete) and (2) FRP (Fiber Reinforced Plastic). On October 15, 2002, Councilmembers Pierce, Howard, and Ruskin along with Brian Cooper, Architect with DES, and Joel Patterson took a tour of buildings in San Francisco where the FRP has been used to restore historic buildings. The age of buildings, as well as detailed ornamentation, was similar to the Historic Courthouse. The FRP was able to capture the texture, color, and feel of the Colusa sandstone. 'The pros and cons of each material can be found in Attachment "B" of this report. Pictures of restored buildings, and examples of the FRP material will be shown to the Council at the meeting. As can be noted by the attachment, the consultants, staff, and Council subcommittee are recommending that the FRP (Fiber Reinforced Plastic) be the material used in the restoration. The cost between GFRC and FRP are very similar, but the construction methods are different, which requires that the plans be done differently. It is for that reason that a decision must be made on the material before we move forward with the design. 6. Exterior liqhtinq of the buildinq. There are existing lights which light up the dome, but the annex building blocks most views from Broadway. Following are the two lighting schemes proposed as part of the design package: -3-
