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

Another winning event of the San Luis Chamber of Commerce’s legislative lunch series. The packed house was treated to a myriad of topics discussed by the terrific trio of Sacramento political insiders-- Cassandra Pye, John Myers and Amy Brown. Moderated by Sam Blakeslee (who did a masterful job of herding cats on fire), this panel discussion was fun to listen to but impossible to explain. They should take their show on the road as it would be a hit with political wonks on both sides of the aisle. Wallace Group is a proud sponsor of these events and enjoys supporting the Chamber.
