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

In 1984 John Wallace helped start the Rotary Club of San Luis Obispo de Tolosa. On June 13, 2018 Wallace Group was named 2017 Business of the Year by the same club.

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.

Sometimes big opportunities take shape in small spaces. For Wallace Group’s Landscape Architecture Department, the model homes at Trilogy Monarch Dunes provided an opportunity to present a wide variety of design solutions reflective of the unique interests and values future residents will have for their front and back yards. Working on a very short timeline, our experienced team was able to provide landscapes that look great from day one, perform year-round, and improve with age. From a French rambling garden that immerses you in the classical prestige of old world Europe, to the contemporary artistry of a turf pyramid within an elegantly chic and modern backyard, and the tranquil respite of a flagstone courtyard filled with tropical plants and a bubbling fountain. All transitioning the resident from the indoors to the outdoors with seamless continuity tailored to complement the interior design. Wallace Group is pleased to share its diverse award-winning designs at Trilogy’s model homes as we wrap up this year’s celebration of Landscape Architecture Month.  To see a fun video of these houses go to https://youtu.be/Pj0LhfpVphQ
