Utility Projects

Categories: Utility Projects

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: 2015

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 project replaces the 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 will also provide 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 is needed from the USFS and the Tahoe Woods Subdivision.

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 project included constructing approximately 1,679 lineal feet (LF) of 8-inch waterline, 143 LF of 4-inch waterline, 532 LF of 2-inch waterline, 5 fire hydrants, and 23 water service laterals. The project was necessary to improve fire hydrant spacing and fire flow rates in conformance with California Fire Code 2010 within the McKinney Tract and the Placer County ROW. The project included approval from Caltrans for an open cut trench for installation of the waterline in Highway 89 right-of-way.

Date of completion: 2008

Project Description: Construction of a replacement sewer pump station for the Grove Street Pump Station including the construction of a new Harbormaster building. This project included a new pump station and associated gravity sewer line, 305’ of 30” sewer line and 615’ of 6” dual force main connecting to an existing sewer main under SR 28.

Date of completion: 2008

This project consisted of ground control and aerial mapping for over 2,200 acres of ranch land for planning of future wastewater conveyance and storage facilities. Deliverables included #D, 2D and DTM mapping files in AutoCAD format on a horizontal datum NAD83 and vertical datum NGVD29, as well as digital color ortho-photography at 0.25-foot pixel.AEC was contracted to map the project area consisting of 2,200 acres.

AEC prepared the Vesting Tentative Map and Final Map for The Summit and Overlook subdivisions at Northstar-at-Tahoe. The Summit Subdivision consists of 15 custom homesite lots. Lots range in size from 20,148 square feet to 32,720 square feet. Future residences to be constructed on the proposed lots would be primarily custom homes. Roadway and most utility infrastructure for the project exist on the site, and would be extended to serve the new lots. Offsite improvements include two 500,000 gallon high welded steel water tanks, a graded tank access, a graded tank driveway, and approximately 6,950 LF of 12" water line. Two skier access trails (approximately 4.8 acres) into the Summit and Overlook were also approved with this project. The Overlook project consists of developing 26 custom homesite lots to the north and adjacent to the Summit. Lots range in size from 14,200 square feet to 18,000 square feet. The AEC survey department provided topographic design surveys, legal descriptions, property research, Final Map processing and approval and subdivision monumentation.
