Hey y’all, my name is Ralph Schell. I have been with Wallace Group for 23 years. I was born in Lancaster, California, but moved to Arroyo Grande when I was 6 months old, so I’m kind of an old timer around these parts. In 1977 I graduated from Arroyo Grande High School (that’s back when AGHS stank at all sports), not anymore! I married my wife Kathy in 1983 and then the kids started showing up. (What’s up with that??) First was Rachel, she’s a 7th grade teacher (so don’t mess with her). Kati (Katrina), she works at Disneyland (big perk there!!). Then came Michael, he’s still in school and working for Lyft (we thought we knew all about kids, until that one came along). We live on 3 acres in the Los Berros area, so it’s very rural out there. My parents bought the property we now own in 1959 (I won’t tell you for how much because you wouldn’t believe me anyway). We’ve been blessed to have made some pretty cool trips; National Parks, east coast, Canada, Mexico, and Europe. I started hand drawing Civil Engineering and Architectural plans way back in 1977, fresh out of high school. In the years since I’ve seen a whole bunch of changes in the industry and community. From the introduction of personal computers to the use of CAD, I’ve designed everything from large subdivisions and shopping centers to houses and remodels. For the past 8 years I have taught a class at Cal Poly called “CE413, Advanced Site Design” in the Civil Engineering Department.   What are you involved in outside WG? Going to Mexico to build houses for people in need (with Hand of Mercy). I'm an elder at my church (First Christian Church, Santa Maria). I coached Youth Football and was a Cub Scout Den Leader for 5 years. Favorite pastime Working inside and outside the house, working on my old cars ('65 Mustang fastback (I bought when I was still in High School), '66 Mustang coupe, ’67 Ranchero), going to Car Shows, model railroading, watching Racing (drag, stock car, dirt cars, F1… You name it), camping, and I still meet with my best friend from 6th grade once a month. Favorite movie Braveheart, Grand Torino, Matrix, Secondhand Lions, and Pride and Prejudice (Believe it or not) What’s your secret ability? MMA :) bbq

Over the weekend, a group of WG employees and their families visited the Camp Roberts Historical Museum. It’s the largest Army museum in California, and it’s less than 50 miles north of WG! The museum is host to exhibits ranging “from the early ranches and the Salinas Indians through World War II, the Korean War, and Vietnam, to present-day mobilizations to the Middle East.” However, the most exciting part for our bunch was the Museum Annex which is the home to dozens of historic vehicles including helicopters, tanks, Humvees, and more. Our group even took advantage of the “Kiddie Corral” dress up corner. As you can see, you’re never too old to enjoy dressing up and climbing around on a bunch of old war machines!

Wallace Group’s own Matthew Parker shares about his experience working on a highly visible project! We are proud to have Matthew as part of our Landscape Architecture department and get to enjoy his fantastic work every day.  Backstory: While at Cal Poly I interned with the Caltrans’ District 5 Landscape Architecture Department. I worked on a wide variety of projects while I was there, but the one I spent the most time on was an interpretive display project aimed at installing interpretive signage for a series of Vista Points along Highways 1, 101, and 154. There are a total of seven viewpoints stretching all the way from the Arroyo Hondo vista point just outside Goleta, to the La Selva vista point near Santa Cruz. Unfortunately, the two vista viewpoints in Big Sur will probably be unreachable for a long time.  The project was a collaborative effort between myself and my supervising landscape architect, along with Caltrans architectural historians. I contributed considerably to each display’s content, designing the board layouts, color scheme, writing much of the text, traveling to libraries and historical societies all over the central coast for research, securing permissions for borrowed content, and creating many of the info-graphics and other graphic renderings. Even some of the photographs are my own. It was a truly rewarding educational experience I will always cherish and one I’m grateful to see people enjoy while traveling along our scenic highways.

Wallace Group started pursuing work in the Tri-County (Monterey, Santa Cruz, and San Benito) area back in 2007/2008. Our second and third contracts were with the City of Hollister for their Sewer and Storm Drain Master Plans. In 2013 the City Engineer requested a proposal from Wallace Group to provide on-call engineering services. The City of Hollister is a bedroom community to the San Jose area and the City was seeing an influx of development coming through their doors and they weren’t able to keep up with the workload. Since we had prepared the two master plans, and our office does private development work, but not in San Benito County, the City found Wallace Group to be a great resource for the on-call engineering and plan checking services. A-5_StormDrainOverview Over the past 3+ years, our engineering resources have completed full Public Improvement Plan Check reviews on over 20 developments, including reviews of the stormwater, water and sewer studies and specifically compliance with all City and Regional Board stormwater regulations. We have completed focused sewer studies as well as the preliminary evaluation and design of the City’s Industrial Sewer/Stormwater Diversion Structure. We are also currently under contract for a Sewer Master Plan Update. To make all of this happen, we have had numerous engineering staff that has supported this wide array of work. Through the plan checking process, the City has requested Wallace Group to assist in the map checking for all of these developments. Our Public Works Department has also helped to provide guidance and support to the City when it comes to the stormwater and sewer regulatory world. They have prepared the City’s SSMP and completed an SSMP update, developed the City’s MS4 Municipal Stormwater Program, assisted with a stormwater NOV and is currently working on the Industrial Sewer NOV. P9 Thank you to all of our Team that has worked on, is working on, and will continue to work on projects for the City in the years to come. Congratulations on a job well done!

The sun brought out over 120 golfers to the 5 Cities Homeless Coalition’s 3rd annual Hope for the Homeless golf tournament this weekend at the Pismo Beach Golf Course! Wallace Group sponsored this event, and our team got some much needed practice. Although no prizes were won, we had a blast enjoying the weather and the delicious food provided by Finn's Restaurant. If you need us, we’ll be at driving range strategizing for how to take home the win next year!
