Provided design for the Highway 267 Martis Creek crossing modification and diversion structure in order to restore hydrologic and sediment transport continuity and wet meadow conditions on the Middle Martis Creek alluvial fan. Goals of the project include eliminating flooding of Highway 267 and other existing infrastructure while maintaining sufficient flow to sustain existing wetland and riparian habitat on the south side of highway 267. Additional tasks included redesign of 3,500 LF of Waddle Ranch Access Road.

The project included the redevelopment of an existing lakefront residence in Carnelian Bay. Close coordination with the North Tahoe Fire Protection District, the Agate Bay Water Company, and utility providers in order to achieve compliance with fire flows, connections, and the necessary utility relocations were required for this technically challenging project.

Date of completion: 2012

The Station 51 original relocation project included site work for a 20,000 square foot public safety center including roadway improvements to Fairway Drive, parking, new utilities and utility relocations, and a storm water collection and treatment system. The Lakeside Trail is the final one-mile segment in the largest paved trail system at Lake Tahoe connecting the existing multi-purpose trails through a highly constrained urban core of Tahoe City, along the lake shore.

Date of completion: 2010

The United States Forest Service (USFS) contracted with AEC to provide design services for this reconstruction and retrofit project. The project included redesigning the day use area to maximize efficiency of the paved surfaces for parking, to increase the number of parking stalls to 160, and to provide BMP’s for the site located in sandy soils very close to shoreline of Lake Tahoe. The site consists of three individual, interconnected parking lots, each of which was graded to allow the stormwater runoff to sheet flow to a large central landscape island.

Date of completion: Winter 2011

The Zephyr Lodge is a 14,000 square foot ski-in, ski-out restaurant lodge located at the top of the Tahoe Zephyr Lift with views off the backside of Northstar. The lodge opened in December of 2011 and is LEED certified. AEC was contracted to provide civil engineering, surveying, SWPPP monitoring, and LEED Certification for the project.

Date of completion: 2017

The Clear Capital Airport Building is a 12,840 square foot modern steel office structure built within Truckee-Tahoe Airport property. The project includes a reconfiguration of the existing airport long-term parking area, circulation and access improvements, storm drainage and water quality treatments, sidewalks, and roadway improvements. AEC provided civil design level services, CEQA and FEMA support, and construction phase services.

Date of completion: 2015

This project involved three main sections of sewer maintained by the Tahoe City Public Utility District in the Alpine Peaks area of the west shore were in need of repair and replacement. The high altitude, steep terrain, and depth of existing lines made this project challenging, but interesting. AEC was able to provide background investigation, surveys, civil engineering design, and construction phase services for this project. Approval processing, funding support, and bid phase services were also provided for the Client.

Date of completion: 2012

This Lake Tahoe Environmental Improvement Project on U.S. Forest Service Land involved construction of a 6-bus inter-modal transit facility, 131-space parking lot, relocation of 450 feet of recreation access road, relocation and extension of 1,600 LF of multi-purpose recreational trails, and all storm drainage and water quality treatment systems. Roadway and drainage improvements to State Route 89 were required for left turn channelization and highway intersection improvements for the relocated recreation access road. The project design incorporated low-impact design principles, extensive use of permeable pavements and advanced stormwater management systems.
