“When it rains, it pours” is not a phrase that staff at the Gamble House Conservancy hopes to utter ever again. For over 20 years, the National Historic Landmark designed by Charles and Henry Greene has experienced water intrusion issues, but in the last two years, the problem has worsened: Thanks to two exceptionally wet winters, two new areas of intrusion have appeared and have behaved differently, confounding staff and hired experts. A 2023 PCF Capital Grant will help the Conservancy thoroughly investigate site drainage and sensitively modify four of the original metal downspouts to prevent future damage from heavy winter rains. 

Executive Director Alexandra Rasic shows PCF board and staff members one of the areas that has had particularly dramatic intrusion in the Gamble House basement.

Built in 1908, the Gamble House is an architectural masterpiece of the Arts and Crafts movement. The home welcomes 25,000 visitors annually, making it a significant heritage travel destination, as well as a beloved community asset for locals.  “This house casts a bit of a spell on people,” says Alexandra Rasic, the James N. Gamble Executive Director. She goes on to say

“We are stewards of this treasured community asset and are grateful that the Pasadena Community Foundation recognizes how important it is to address structural issues as they arise so that we can preserve this landmark for future generations.”

PCF staff and board meet with the Gamble House Conservancy staff to learn about the water intrusion problems at the historic landmark.
