We are supporting a new water recycling facility at the zoo’s safari park, utilizing our experience with pre-packaged treatment solutions. Spanning over 1,800 acres, the safari park is a sprawling wildlife sanctuary and a protected native species habitat. It is home to over 3,000 animals and a botanical collection of 3,500 species and 1.75 million specimens, making water a huge priority for developing and maintaining the habitat.

Our very own civil engineer, Sarah Huffman, presented on roundabout and channelized turn lane accessibility challenges for the visually impaired to a group of eager coworkers today. She recently attended a conference where she learned how to make designs as intuitive as possible for blind people, especially those traveling to unfamiliar intersections. Sarah provided a valuable educational opportunity, teaching us about various design treatments and how they can make a big difference. Thank you Sarah!

Earlier this year Montecito, California was ravaged by wildfires, heavy rains and mudslides resulting in a massive cleanup of the horrific amount of debris incurred. The Wallace Group survey team has been assisting in these efforts by calculating how much debris basins in this area can hold in the future. Using a scanner and unmanned aerial vehicles (UAV) the team took orthorectified photos, removing the angles and tilts of a photo, resulting in a true representation of the positions of the image. A large photo of the entire work area will then be used to create a map for developing a volume calculation of the debris basins. With this calculation Montecito can improve future disaster plans, should these events take place again.  Watch a short video of the area at   https://youtu.be/YUaJysTT7Qo
