Document Description
The purpose of this project is to rehabilitate portions of the Vallejo Home Chalet at Sonoma State Historic Park and humanely exclude bats from roosting in the interior of the second floor to aid in the long-term preservation and continued use of this historic building. Rehabilitation work will focus on a set of doors on the second floor, west elevation, of the building. Work will:
• Realign the doors to close an existing gap between the frame and the door;
• Add wood trim to ensure the realigned doors are watertight; and
• Add blocking between two (2) existing wooden hoist beams to further seal the building’s interior.
Additional work will include plugging small holes with expanding foam, steel wool, wood trim or via other appropriate methods and remove the existing felt paper covering the second story floor and replace with in-kind materials.
Temporary bat exclusion measures will be installed so bats are able to leave the structure but not access the interior of the structure when they return. These one-way exits will remain installed for a multiple consecutive day period. Once exclusion is confirmed, permanent exclusion measures (expanding foam, wood trim, steel wool, etc.) will be installed and the temporary exclusion structures will be removed. In addition, two (2) bat boxes will be installed in the vicinity of the Vallejo Home Chalet to provide a new area for roosting. This work will occur during seasonal periods of low bat activity; about March 1 – April 15 or September 1 – October 15.
