Due to a very successful year for visitation to Mammoth Lakes, Town Council was able to allocate funds above and beyond the 2016/17 Road Rehabilitation budget towards this work. In the summer of 2017, the Town, through a contract of about $1.3 million with Spiess Construction was able to complete a number of significant maintenance projects throughout Town.
Road Rehabilitation Projects Around Town
A complete rehabilitation of the full pavement section of the Hillside Drive loop north of Forest Trail, including Hillside Place and Hillside Court was completed. Concrete valley gutters were replaced at each intersection with Forest Trail. Upper Chateau from Azimuth Drive to Minaret was pulverized and repaved with new asphalt. The corner was softened and the cross-grades were reworked. The entrance north to the Snow Pit on SR 203 east of the visitor center was removed and replaced with 6” of asphalt after a hard winter of many large trucks hauling many loads of snow at all hours of the day and night. There was also a significant amount of micro-surfacing in a few areas of Town, including Meridian Boulevard from Sierra Park to SR 203.
The Knolls area and Chateau East from Old Mammoth Road to its east end. This treatment is a combination of liquid asphalt oils and graded clean sand (like a sandy slurry seal with some larger rock and Portland cement added. This treatment can extend the life of existing surfaces by several years. Approximately six miles of the Lakes Basin Multi-Use Path received a fog seal and restriping from Minaret Road up to and throughout the Lakes Basin to the Horseshoe Lake parking lot. The lower loop of the Town Loop multi use path from lower Wagon Wheel to Sierra Park Road near the Courthouse received deep crack repairs and a slurry seal.
Southern California Edison Projects
Southern California Edison was very busy in the right-of-way this year. They received 42 Encroachment Permits in Town. They also made significant progress in the Lakes Basin, finishing work just as the gates were being closed for the winter. They were able to trench and bury approximately 3,000 feet of conduit and vaults to mitigate power problems encountered last season. Final repaving work will be addressed next spring.
Upper Main Street Retaining Wall and Pedestrian Improvements
The Town completed retaining wall improvements along SR203 from Mountain Blvd to Viewpoint Road. Temporary asphalt was placed for the coming winter 18 to assist pedestrian safety and walkability along Main Street. A new bus shelter will be complete in early December. From April through June of 2018, work will resume, with construction of the concrete sidewalk, bus turnout and minor drainage improvements.
