Fort Bragg Franklin Street Reconstruction, City of Fort Bragg 
Green Valley was tasked with the design of a reconstruction and overlay project of approximately one mile of Franklin Street in downtown Fort Bragg. Franklin Street is the major north-south arterial running through the heart of the commercial area.

The project was very challenging due to extreme cross slopes within the traveled way and frontages that were non-conforming to ADA standards. Many pedestrian ramps, sidewalks and driveways were reconstructed to comply with these standards, and detailed grading plans were prepared for many of these features throughout the project limits. The roadway reconstruction was accomplished by a myriad of construction techniques to save money on the project. Depending on the condition of the road and geometric constraints, portions of the road were completely reconstructed, portions were overlayed with spot dig-outs, and portions were recycled using "cold foam asphalt" technology.

The project also included many streetscape enhancements that were incorporated to make the corridor more pedestrian friendly. These enhancements included curb return bulb-outs, decorative asphalt stamping and paving tiles, and installation of new street lighting and street furnishings.

Pierson Reach Pedestrian Bike Path, Santa Rosa   
Winner of 2005 CELSOC Engineering Excellence Award
This half-mile-long path connects Santa Rosa's "historic" Railroad Square with the City's downtown area. Pierson Reach is an urban design and restoration project that stretches along Santa Rosa Creek and allows the community to enjoy the lush creek and riparian ecosystem within the natural environment. The overall Santa Rosa Creek Master Plan envisions that adjacent property owners will reorient their buildings towards the creek where public gatherings, art exhibits, and pedestrians will utilize the pathways and enjoy the natural habitat of the area. Green Valley Consulting Engineers provided complete structural and civil engineering services for this recently constructed project. As a part of design, extensive permitting was required from six separate agencies.

Sonoma County Regional Parks-West County Bridge 
The West County Trail Bridge Phase 2b project is a bridge over the Santa Rosa Creek that links the Prince Memorial Greenway with the Joe Rodota Trail. Green Valley was the Project Engineer/Manager and provided hydrology/hydraulic calculations to set the chord elevation of the prefabricated truss bridge as well as designing the bridge abutments and connections. Green Valley also designed the civil site improvements for the circular connecting focal point on the north bank, in conjunction with a landscape architect Don McNair. In addition, Green Valley provided construction staking services for this project and was responsible for extensive permitting with the Sonoma County Water Agency, City of Santa Rosa, Dept. of Fish and Game, US Army Corps of Engineers. Extensive soil remediation was required due to contamination.

R4 Effluent Storage Reservoir, Sonoma  
The project scope included a 300 acre-feet earthen reservoir designed to California Division of Safety and Dams regulations, a 2,700-gpm pump station with associated electrical controls and telemetry, piping, valves, flow meters and a cathodic protection system. The design of the storage reservoir required earthen embankments 18 feet in height, an impermeable flexible membrane liner, and a separate groundwater pump station used to alleviate high ground water problems. The additional storage provided by the reservoir will allow our client to decrease discharges to surface waters during critically wet years and provide additional reclaimed wastewater to area vineyard owners for irrigation purposes.

Mendocino Avenue Water and Sewer Main Rehabilitation 
The Mendocino Avenue Water and Sewer Main Replacement was an extensive reconstruction project which included the replacement of 100-year old water and sewer mains, including the upgrade to 12" water mains with new fire services on a 4-lane major thoroughfare through 4 signalized intersections.

Construction staging was critical as Mendocino runs thru the heart of the downtown commercial and retail center of Santa Rosa, as well as serving multiple high rise residential complexes. Over 19,000 thousand motorists use the thoroughfare on a daily basis. To facilitate construction, a detour plan was made to convert the Avenue to one-way traffic. Extensive staging and traffic control plans were created by Green Valley for the turnover.

The street reconstruction included stamped and colored asphalt concrete at key intersections and ADA upgrades of pedestrian ramps at all intersections.
