DAA JDESIGN ARCH ITECTURE+INTER IORS PARKING Description: Parking on the site is provided by a one -car garage located in the southwest corner of the site, abutting the south alley and facing Jefferson Avenue. There are no records for when the garage was built, but it is mentioned on the 1948 Boulder County assessor's card and the construction type is typical of that timeframe for the Louisville area. The building is constructed of 8x8x16 CMU block walls supported by a concrete foundation of unknown depth, and it is not clear if there is a footing. The garage roof is constructed with 2x6 roof rafters at approximately 17 inches on -center and sloping down towards the east. The rafters bear on 1x sill plates along the east and west CMU walls and are spliced on a mid -span 6x6 beam that bears on the north and south walls. 01% The garage roof sheathing is constructed with 1x12 skip sheathing. There is a poured concrete slab floor and a poured concrete driveway to Jefferson Avenue. The exterior finish is a steel siding that was applied in 1988, according to building records. This is after the steel siding was added to the house in 1974. The overhead door facing Jefferson is a painted wood door. There is a painted wood person door and three single -pane, divided lite windows on the north side. Garage interior, showing CMU walls & roof construction. Condition Evaluation: Southwest corner of the garage. The garage is in fair condition. Minimal assessment of this structure was made due to the lack of information of the date of construction. The garage meets the criteria for an historic structure as it appears to have been constructed prior to 1948. However, the current condition of the garage does not contribute to the overall historic context of the 700 Pine site. There are several significant cracks in the CMU wall, finish materials of the parapet appear to be deteriorating or have detached, and it was difficult to fully assess the roof. Furthermore, it is difficult to determine if the garage is supported by a proper foundation. Recommendations: 1. The garage should continue to perform adequately for its intended use. Consult a licensed structural engineer if any modifications are to be made. Grouting of the CMU walls, strengthening of existing roof framing and verification of the type of foundation and footing below the perimeter CMU walls are some of the likely repairs needed if new loads are to be added to the detached garage. 2. Repair, refinish, or replace the garage doors and windows. 3. Remove the steel siding. Upon removal, further analysis of the CMU walls and roof structure should be made by a licensed structural engineer. 700 PINE PAGE - 11
