Roadway realignment and Roundabout – In 2007 the functional classification of the master planned roadway, Muller Parkway, was upgraded from a major collector to a minor arterial in the Douglas County Transportation Plan. Later in that year, Douglas County adopted a revision to the Douglas County Design Criteria and Improvement Standards (Design Manual), which required separation of collector and arterial roadway intersections to be a minimum distance of 1,320 feet. This resulted in an inconsistency between the Transportation Plan for the Pinenut Road/Muller Parkway intersection and the Design Manual’s traffic requirements.
Peri Enterprises retained R.O. Anderson to prepare an amendment to the Transportation Plan in order to correct this inconsistency. The amendment included the relocation of Pinenut Road (a master planned collector road) as it intersected with Muller Parkway, as well as, an amendment to the Trails Plan consistent with the realigned roads, and to adjacent land uses.
Following approval by the Douglas County Board of Commissioners, R.O. Anderson designed the project and prepared the plans, technical specifications, and cost estimates for Peri Enterprises who will both dedicate and construct these regional road improvements. Design considerations included re-alignment of Pinenut Road further to the north to allow for adequate vehicle stacking on Muller Parkway; design of the storm drain system to accommodate these improvements and existing flows from the historically agricultural project area; abandonment of approximately 1,250 lineal feet of the existing Pinenut Road north of the intersection with U.S. Highway 395; removal of the existing asphalt concrete (AC) roadway; design of a roundabout at the intersection of Muller and Pinenut Road; and the design of the new AC roadway with lighting, curb and gutters, water, sewer, storm drain, sidewalk and bike path improvements.
The project is now well under construction with an anticipated completion date of Spring 2012.
Situated north from Mammoth Lakes, California, Bridgeport is a small, unincorporated town. The Bridgeport Public Utility District received approval for $4.1 million in grant and loan funds from U.S. Department of Agriculture Rural Development to improve and repair the sewer and water system serving the town of Bridgeport. The Bridgeport Public Utility District retained R.O. Anderson for all aspects of design, land surveying, and construction management through this multi-phased project. The scope of work involved significant improvements to existing community systems, including adding a new municipal well, well house, and office building; design and construction of two new water storage tanks; upgrades to two existing lift stations; complete replacement of one lift station; new water mains; and installation of a telemetry control system for all new and existing facilities.
