Bodean Rock Quarry Solar Panel Project  
2011 ASCE North Coast Section Special Project of the Year Award
2011 North Bay Business Journal Top Real Estate Projects Award
The Bodean Company—an aggregate and asphalt supplier located in Santa Rosa, California—acted upon its commitment to sustainability by installing the largest solar panel system of its kind at its Mark West Quarry location. With 3,444 solar panels, this innovative solar power project is the largest in the western United States and makes the BoDean Company the first quarry in the world to go 100 percent solar at one of its quarry sites. The impressive new system is capable of generating 1.165 megawatts of green electricity annually and offsets the release of 1,844,521 pounds of Carbon Dioxide (CO2) per year—the equivalent of driving 2,494,595 miles in an average car.

Green Valley Consulting Engineers was retained by Stellar Energy to provide "very precise" construction staking for 864 Terrafix earth screws used to anchor the solar panel rack system to the steep quarry terrain. The almost vertical rock mining site posed intriguing challenges since Green Valley's work needed to be conducted on a steep 1:1 or 2:1 angle slope requiring the use of special terrain screw mounting systems and shotcreting for erosion control. Because of the physically exhausting landscape and the need to stay ahead of a tight installation schedule, Green Valley needed to 'think outside of the box' and decided to employ "quick stakes" which are lighter and faster to place—taking roughly 1/3 less time when compared with traditional "lath" stakes.

Stony Point Plaza Redevelopment  
2011 North Bay Business Journal Top Real Estate Project Award
Green Valley Consulting Engineers played a pivotal role in the transformation of a once blighted, rundown, and essentially abandoned Plaza, into a beautiful, 88,000 square foot sustainable retail center complete with pedestrian and bicycle friendly outdoor spaces. The new artful Stony Point Plaza is now home to big name retailers offering hundreds of jobs to residents and offering fiscal stimulus to the local economy.

The Stony Point Road Plaza is located within the City of Santa Rosa’s largest housing growth area and situated along one of the busiest and most congested cross-town arterial locations. Bordered by State Highway 12 and the highly trafficked Stony Point Road, this central trade area serves over 175,000 people. Green Valley provided comprehensive civil engineering design services for the complete site development of the project including incorporating progressive low impact development storm water management design, decorative and eco-friendly landscaping, and pedestrian and transit oriented improvements.

Kaiser Air Expansion—Charles M. Schulz-Sonoma County Airport 
Green Valley is providing on-going engineering services for the Oakland based KaiserAir for their expansion at the Charles M. Schulz-Sonoma County Airport. The expansion is the largest private development in airport history, estimated at $6 million. Improvements include a fuel depot, new hangars, private terminal, and aircraft ramp on 7-acres of leased land at KaiserAir's Santa Rosa Jet Center.

Green Valley's services include site improvement plans for two—20,000-gallon, above-ground jet fuel tanks, a new 30,000-square-foot hangar, a sewage dump station for private aircraft and utility infrastructure plans for on-site water, fire protection systems, and sanitary sewer mains. Innovative storm water solutions which utilize CONTECH media filters are being employed to help target site specific pollutants. Extensive permitting was required from multiple agencies. Work to supplement the permitting included the preparation of SWPPP and spill prevention containment and control plans (SPCC Plan).

Moore Chiropractic Office  
Moore Chiropractic office is located in the heart of Santa Rosa on at the intersection of West Steele Lane and County Center Drive. A new state-of-the-art, 10,000 square foot office space located on the corner of a major intersection in Santa Rosa, Green Valley provided complete civil engineering site development services which included stringent ADA requirements.

Bridgeford Hanger, Napa County Airport, Napa   
Considered one of the finest general aviation airports in the Bay Area, Napa County Airport has been expanding to meet increased demand for hanger space. The airport is used by Bay Area executives, the wine industry, and tourism related industries. Working with GCCI General Contractors, Green Valley was responsible for the design of a recently constructed 12,000 square foot hanger and apron facilities on the airport site.

Green Valley's scope of the project included a detailed topographic survey to establish drainage patterns, preparation of civil design drawings indicating new grading, drainage and utility improvements, runway conforms and improvements, retaining walls, parking lots, erosion control measures, and construction administration duties. Our engineers prepared hydrologic and hydraulic calculations for approval from the Napa County Flood Council, and also coordinated connections into county water and sewer facilities.

Pride Mountain Vineyard, St. Helena 
This 170-acre internationally acclaimed wine estate straddles the Napa/Sonoma County line and is situated on the rugged and steep terrain of Spring Mountain. The estate consists of lush, mature vineyards, a winery with visitor's room and over 2100 feet of subterranean wine caves. In addition, the remains of the original 1890 Summit Ranch Winery still exist on the property, used up until the prohibition era.

When Jim and Carolyn Pride decided to expand their vineyard holdings and make various infrastructure improvements on the property, they turned to Green Valley Consulting Engineers to assist them with their plans. Green Valley provided permitting assistance, site grading, hydrology and drainage design, and erosion control and construction support services. The project offered the unique challenge of balancing storm water runoff and extensive erosion control measures associated with steep mountain slopes with the requirement of maximizing all available land for vineyard planting.
