The Groundbreaking Ceremony for the San Miguel Community Park Expansion Project was held on December 16th that kicked off the construction of the 5-acre community park in the heart of San Miguel. With the recent restoration of the historic Mission San Miguel, the downtown streetscape enhancements, and the recently constructed San Miguel Gateway Monuments, the city has significant new community assets in place. The San Miguel Community Park Expansion Project will offer opportunities for community gatherings, increased recreational opportunities, venues, and commerce that will attract visitors to the town of San Miguel and help fuel its redevelopment.   Tractor   The existing park is currently bisected by K Street creating two small, narrow park areas. The proposed expansion project will remove one block of K Street by paving and underground the existing overhead utilities between 12th and 13th Streets. Removing the stretch of K Street that goes through the park will divert traffic to L Street thus requiring L Street to be widened. WG is also involved in the L Street Widening project. These different but interconnected projects are tied together by a grant. Additional park improvements include creating a multiuse sports field, ornamental landscaping, LID Bioretention facilities, water efficient irrigation, custom park signs, park furnishings, playground enhancement, fencing, multi-use trail, sidewalk, and parking lot. Challenges included a tight construction budget, working with non-existent storm drain facilities, pedestrian and user safety, salvaging as many existing trees as possible, and designing around an existing residence. The challenges were vetted and creative design solutions reigned as an exceptional product was delivered on time and within budget thanks to the hard work of many! The project exemplifies a successful multi-discipline effort from Wallace Group. Led by the Landscape Architecture Department, Brandon Medeiros, our Director of Landscape Architecture, managed the conceptual design, community engagement process, and development of the bid documents. Our Landscape Architecture team handled irrigation, hardscape, specifications, and planting design! Our team of Civil Engineers tackled the Caltrans specifications, grading, drainage, technical memorandum, and provided drafting support. Our Survey Department prepared the topographic, boundary, and easement base map. Other WG efforts included community engagement support, PG&E and underground utility coordination, and offsite road design improvements. Construction completion is scheduled for summer of 2017! We are happy to be a part of this incredible project, and we are proud of all of our employees who helped make this a reality for the wonderful community of San Miguel!   Master Plan Render

My name is Marco Castaneda, and I have been working at WG for 18 months as a Survey Technician. I grew up in the outskirts of Manteca, California where I was surrounded by dairies and orchards for miles in every direction. I went to East Union High School where I played soccer and wrestled. After graduating high school, I attended Fresno State which was a short two-hour drive from my home town. I always enjoyed math and science, so I knew I wanted to go into the engineering field. After speaking with a counselor, I ended up choosing to study Geomatics Engineering. Having the option to work in the office and in the field was very appealing to me. During my senior year, I saw an opening at WG and applied! Living in the valley my entire life, I was ready to move to the central coast and experience something new. I graduated in the spring of 2015 and got hired on at WG shortly after. Since moving to San Luis Obispo I have been able to explore the area and enjoy the wonderful weather. I have really enjoyed hiking the various trails, checking out the wineries, and exploring local attractions. To stay in shape, I attend a local Brazilian Jiu-Jitsu (BJJ) gym. I dedicate a large portion of my free time to BJJ and have been able to compete in a few tournaments. Although it is incredibly difficult and it leaves my body aching, the challenge to get better gives me the motivation to keep going back.   Describe what you do at WG I take measurements in the field and draft maps in the office. What are some of your favorite activities with WG? Tamale Day! What are you involved in outside WG? I haven’t gotten around to this yet, but it is on my to-do list. Favorite pastime Binge watching documentaries on Netflix Favorite movie The Dark Knight, Rush Hour, and Forrest Gump Favorite food Thai or Mexican food Describe your dream vacation. Exploring South American countries like Peru, Argentina, and Chile What’s your favorite childhood memory? My favorite childhood memory would be going to Manteca Waterslides (before it closed and broke every kid’s heart). What’s your secret ability? I can make some really good salsa! What is the furthest away from SLO have you been? It’s pretty close between Baltimore and Miami.

This winter season, San Luis Obispo County has already seen freezing temperatures on more than one occasion. WG employees donated 5 sleeping bags and 15 blankets and comforters, and our Charitable Contributions Committee purchased $225 worth of new blankets! This generous donation will be spread to three warming shelters throughout the County. We hope to help everyone stay warm for the Holidays and beyond!
