Client: Nevada Department of Transportation

Project Name: I-580 Freeway Extension from Washoe Valley to Mount Rose Highway

The project consists of the construction of approximately 8 miles of a new six lane controlled access freeway. The freeway is being constructed over or adjacent to several Waters of the US, wetland areas and Waters of the State. Work includes large roadway cuts and embankment fills, roadbeds grading, cut & fill slope stabilization, landscaping, roadway stabilization, drainage structure installation, asphalt concrete paving and Portland cement concrete. The project also includes constructing two interchanges, two grade separations, five bridges, MSE walls, underground utilities, highway lighting, and a bridge deicing system. ESE is providing full time inspection for roadway excavation and embankment placement, roadway stabilization, underground utility installation, structural backfill, structure excavation, slope stabilization and landscaping. In addition, the project includes two concrete batch plants dedicated to the production of Portland cement concrete for the project. ESE's Certified Professional in Erosion & Sediment Control (CPESC)  is inspecting the project and batch plants; and reviewing the SWPPPs for compliance with the NPDES permit, NDEP temporary working in waterways permit, Corp of Engineers Individual Permit, the NDOT BMP Manual and NDOT specifications related to SWPPP Compliance.

Project Name: Grove Street Safe Routes to School Project

ESE provided design, construction management, full time inspection and material testing services for the Grove Street Safe Routes to Schools project in Bishop, California. The project included the construction and re-construction of curb, gutter, sidewalk, pedestrian ramps, driveways, AC roadway, drainage improvements, extensive water and sewer upgrades, and parking facilities from Highway 395 to Home Street. All improvements were designed to meet the Americans with Disabilities Act (ADA), as well as California accessibility standards.

The project required extensive public outreach/interaction which incorporated presenting project details at public meetings; working with residents concerning property specific issues from the design stage through construction; addressing environmental concerns to ensure timely project delivery; and coordinating with local and state government agencies such as Caltrans, California Division of the State Architect (DSA), and environmental agencies. ESE also coordinated construction surveying for the project.

Client: Town Of Truckee

Project Name: Pioneer Trail Roundabout

ESE and team members provided civil engineering design services for a roundabout in Truckee, California at the intersection of Pioneer Trail Road and Donner Pass Road. The project consisted of the layout and design of a two lane roundabout to be initially constructed as a one lane roundabout and then retrofitted at a later date as a two lane roundabout. This design considered grading and drainage of the roundabout in both a one lane and two lane configuration. In addition, the project included the design of Class 1 bike/ADA accessible trails on both sides of Donner Pass Road from the SR89 Roundabout to the I-80 overpass. Landscaping, drainage and lighting were also components of the design. Construction of the one-lane roundabout was completed in the fall of 2009. The construction of the trails and landscaping were completed in the fall of 2010. ESE provided complete drainage design, utility coordination, geotechnical investigation, storm water pollution prevention plans, final design plans and specifications. The construction cost of all the improvements was approximately 2 million dollars. 

The roundabout improvements provide a safe crossing for bike and pedestrians to the new community center from Pioneer Center and the Middle School while creating another important leg of the Truckee Trails bike plan. This project utilized bio-swales and creative planting to integrate storm drainage with recreational uses which provided an aesthetic extension of the future link to the downtown for school children and adults alike.

Project Name: Silver Lake Road Rehabilitation

ESE provided design, construction management, full time inspection and material testing services for the rehabilitation of Silver Lake Road from Silver Shores to 1,100 feet east of Stead Boulevard. The project included 750 lineal feet of minor patching and application of micro-surface seal within the corrective maintenance section and approximately 7,700 lineal feet of complete reconstruction of the existing roadway using in-place pulverization and cement treatment followed by new asphalt concrete pavement. The project also included sidewalk, curb and gutter, pedestrian ramp upgrades, bus stop improvements, drainage improvements and striping re-alignment to accommodate new bike lanes along the roadway extending to Red Rock Road.

Project Name: 2008 Water Main Replacement Project, Kings Beach, CA

The project included replacing 2,800 linear feet of 6” water main on Cutthroat Avenue from Wolf Street to Fox Street and the installation of new fire hydrants on Speckled Avenue from Wolf Street to Chipmunk Street and on Cutthroat Avenue from Wolf to Fox Streets.  The project also included milling the existing asphalt concrete surface and placement of a 2” overlay. Because construction prices for this project were lower than expected there were additional funds available to replace 275 linear feet of 6” water main on Wolf Street between Cutthroat Avenue and Speckled Avenue.  ESE amended the permits and modified the design quickly so the contractor could start the construction at the intersection of Wolf and Speckled by the contract start date.  ESE services included Placer County permitting, TRPA permitting, public outreach, final design, and material testing for the installation of the new water main and services to approximately 65 homes.
