This water quality project included construction of curb and gutter, storm drain facilities and relocation of existing utilities within Placer County roadways throughout the Kings Beach grid area.

Date of completion: 2012

Prepare BMP work plan to comply with TRPA’s request to come into compliance with TRPA requirements regarding onsite water quality treatment and BMP installation.

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.

Date of completion: Fall 2012

The wetland mitigation project represents a collaboration between the North Tahoe Fire Protection District (NTFPD) for impacts associated with their new fire station, and the Tahoe City Public Utility District (TCPUD) for impacts associated with the Lakeside Trail. AEC identified a joint project that would address feasible and appropriate mitigation needs for both sets of impacts. 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. The purpose of this project was to mitigate the permanent and temporary impacts to existing wetlands. The project area that was selected meets the criteria set forth by current U.S. Army Corps of Engineers Final Mitigation Guidelines and Monitoring Requirements, and as mandated by the Water Quality Certification Permits (401 Permits) issued for both the NTFPD and TCPUD projects. The mitigation project is currently being monitored annually by AEC and its biological subconsultants.

Date of completion: Summer 2012

The Lakeside Trail Project connects existing multi-purpose trails through the urban core of Tahoe City, along the lake shore. The project involves roughly one mile of trail and includes amenities such as plazas, landscaping and interpretive signage.

The project involved dredging of lake access to the previous dredged elevation of 6220’ to enable boat operation at lower lake levels. AEC was retained for civil design, topographic and bathymetric surveys, construction inspection/monitoring, as well as permit compliance. AEC provided TRPA, Lahontan, CDFW, and California State Lands permitting compliance/acknowledgement as well as obtaining environmental clearance for a California State Parks Right-of-Entry in order to facilitate an early construction start date.

Date of completion: 2013

The project includes the acquisition of the assets of the Lake Forest Water Company by the TCPUD, and the reconstruction of the water system within the Lake Forest Water Improvement District (LFWID) service area to meet federal and State drinking water standards, as well as fire protection standards. The reconstruction project consists of approximately 2,500 lineal feet (LF) of 10-inch pipe, 7,500 LF of 8-inch pipe, and 600 lineal feet of new 4-inch pipe to be installed to replace the existing water system in the area. Water meters will be installed with new service laterals to each customer, and 27 fire hydrants will be installed within the roadway right-of-way. Fire hydrants will be spaced approximately every 400 feet as required by the California Fire Code (Fire Code) and the North Tahoe Fire Protection District (NTFPD). An interconnection would tie the new system to the existing TCPUD water supply and storage system, which surrounds the LFWID. Currently, TCPUD provides water service to approximately 3,910 customers within their existing service area. The TCPUD has adequate water supplies, storage and transmission to provide water service to the approximately 118 additional customers that would be added by the Project. Replacement of 10,000 LF of small diameter and back-lot water mains.

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 as well as CEQA and FEMA support.
