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.
