The Tahoe Truckee Unified School District (TTUSD) completed the construction of their Transportation Maintenance Facility (TMO) in Fall 2003. AEC was involved in the survey, civil design, and portions of the permitting for this project. The TMO facility proposed new construction to house the TTUSD Transportation Department Administration Facilities, enclosed parking for 6 to 14 school buses, a vehicle repair facility for the maintenance and repair of school buses and other District vehicles, and a Transportation Department refueling facility. Additionally, on site parking was provided for public parking with 17 standard stalls and two accessible stalls, employee parking with 74 standard stalls and one accessible stall, and outside parking for 40 standard 40' school buses. The AEC survey department provided base mapping for planning, civil design, and the construction staking for this project, as well as legal descriptions and exhibits to accommodate the lease of the land to TTUSD. This required research of title reports, deeds, existing easements, and assessor's maps.

Schaffer’s Mill is a 475-acre planned development located in Martis Valley, east of Truckee, California. AEC was retained to design and develop improvement plans for the amenity parcels consisting of a clubhouse, restaurant, cart barn and sales center, and a parking lot with 123 spaces. Site amenities included tennis courts, pool, and sport court with separated restrooms. In addition, AEC has provided Construction Documents and Final Maps including field surveys, easement descriptions, utility, roadway, and lot layout, drainage, and construction phase/staking services for golf maintenance facilities, development of 109+ townhomes and over 100 custom lots.

The project included the replacement of the entire 36-inch sewer main pipeline as it crosses the Truckee River in Tahoe City, CA. AEC completed the surveying and base mapping required for design and permitting for the project. Survey services included topographic and boundary surveys, location of physical features in the Truckee River channel, and depiction of 100-year floodplain limits. Permits required for the project include a US Forest Service Special Use Permit, a California 401 Water Quality Certification and Basin Plan Exemption, a CA Department of Fish and Wildlife Streambed Alteration Agreement, and Caltrans Encroachment Permit for construction staging and access within the Caltrans Maintenance Yard.

The Lakeside Trail is a one-mile segment in the largest paved trail system at Lake Tahoe, connecting the North Shore, West Shore, and the Truckee River and Squaw Valley. This segment courses through the core of Tahoe City in close proximity to the Truckee River and Lake Tahoe and was developed in seven phases due to its complexities. Water quality and coverage mitigation strategies were successfully implemented throughout the trail and allowed for enhanced restoration of areas that had been previously disturbed. Managed public access and friendly barrier features have kept users on the trail and away from sensitive areas. Major utility upgrades and relocations as well as storm water treatment facilities and source control measures on and off site were key benefits of the trail.

The project included a complete refurbishment of the park area. This involved upgrading the playground to meet current safety standards; relocation of the restroom building to a more accessible location; reconstructing the sewer pump station and force main; highway streetscape improvements including removal of existing boardwalk and railing, installation of a depressed walkway surfaced with concrete pavers and cable railing. Beach improvements included placement of 12,000 cubic feet of imported sand in former grassed areas. Shoreline stabilization was necessary to protect the beach, and a dynamic rock revetment was designed to mimic natural conditions. Other work included restoration and stabilization of the steep slopes and existing foot trail, providing ADA access to restrooms, interpretive displays of Tahoe history, a picnic terrace area and overlook areas, and a reconstructed parking area with advanced stormwater BMP’s due to proximity to Lake Tahoe.

This project was in coordination with the North Tahoe PUD Utility District, located within the Carnelian Bay and Tahoe Vista areas. AEC compiled a comprehensive list of the potential utility conflicts that could arise during construction of the Caltrans Erosion Control Project. AEC developed improvement plans for the relocation of gravity sewer systems and the water transmission pipelines. AEC also provided construction inspection services for the relocation of those facilities.

State Route 89 between Squaw Valley Road and Tahoe City was reconstructed by Caltrans during the summer of 2010. The project has included several vehicle pull-outs along the highway, which, in turn, have become heavily utilized for recreational access to the Truckee River and the Truckee River Bike Trail. However, there was no direct or formal access to the adjacent bike trail or river from the pull-outs. As such, informal access was occurring at multiple locations causing safety concerns as well as erosion between SR 89 and the bike trail. AEC provided survey, civil design, permitting, and construction inspection services for the implementation of permanent BMPs and improved access.

Complete design services for a water line interconnection between Tahoe Cedars Water System and McKinney Quail Water System (MQWS). In anticipation of TCPUD’s acquisition of the Tahoe Cedars Water System, the project increases the capacity and storage capable of delivering sufficient fire protection requirements to all areas of Tahoe Cedars for both districts. In addition to adding fire hydrants to meet current fire protection requirements, the project also improves water system operations by providing source redundancy.
The Jackpine Public Parking Facility, located in downtown Tahoe City provides parking for approximately 40 vehicles. AEC began this project with the Redevelopment Agency providing topographic and ALTA surveys of the site for acquisition purposes. Initial steps were then taken by AEC to evaluate the development potential of the site, including processing of site assessment applications with TRPA, and based on the results, preparation and processing of Land Capability Challenge applications with TRPA to re-delineate the Stream Environment Zone on the property. In parallel with the above work, AEC prepared an evaluation of parking options, including a summary of regulatory and engineering opportunities and constraints for each option.

The project replaces an existing 2,500 LF small diameter tank line from the Four Season water tank to the Tahoe Woods Subdivision with 12″ tank line to provide fire flows that comply with the California Fire Code. The new line also provided electrical service to the water tank to enable the TCPUD to remotely monitor the water level inside the tank. Special considerations in this project include close coordination with the USFS. The water tank and waterlines are on USFS land acquired through the Burton Santini Act. A USFS Special Use Permit, including specific resources documentation and analysis as well as proper legal privilege was needed from the USFS and the Tahoe Woods Subdivision.
