Markleeville Creek Floodplain Restoration Project

Markleeville Creek Floodplain Restoration Project

The Project is located in Alpine County, California, in the town of Markleeville on the north side of Highway 89, in the US Geological Survey Markleeville quadrangle map, NE ¼ of the SE ¼ of Section 21, Township 10 North, Range 20 East, Mount Diablo Base and Meridian. The approximate Project center is located at coordinates 38.694051, ??119.77853. Within Markleeville, the Project is located immediately east and downhill from the Alpine County Administration Center. Land uses to the north and west are urban (commercial and public), while those to the south and west are residential. Land uses to the east are a mix of rural agricultural, public institutional (including the Project site), and open space/recreation. The Project boundary includes an approximately 6.65-acre area (or Project site) that formerly housed the US Forest Service (Forest Service) Markleeville Guard Station. The site includes Markleeville Creek and immediate adjacent areas downstream of the Markleeville Creek Bridge on Highway 89 and Millberry Creek downstream of the MPUD access road to its confluence with Markleeville Creek. The parcels within the Project boundary are primarily owned by Alpine County (Assessor Parcel Numbers 002-280-002-0, 002-280-003-0, 002-280-005-0, and 002-280-006-0) and include a portion of a private parcel along the MPUD access road (Assessor Parcel Number 002-260-002-0). The MPUD holds access easements along all pipelines and a blanket access easement that includes the access road. A portion of the site lies within the Caltrans right-of-way (ROW) along Highway 89. Alpine Watershed Group (AWG) with support from and coordination with MPUD and Alpine County developed design plans to the 95% level for the 2015 Project. The 2015 Project was and is a priority floodplain restoration project for the Upper Carson River Watershed. The goal of the 2015 Project was to restore the natural form and function of Markleeville Creek at the site of the former Forest Service Markleeville Guard Station. The 2015 Project had three major elements: sewer system modifications, floodplain restoration, and public access improvements. Since 2015, it has been split into two separate and distinct projects, with separate funding sources: • The sewer improvement project, led by MPUD and to be funded by Clean Water State Revolving Fund financing; and • Markleeville Creek Floodplain Restoration Project (Project or restoration project), which includes floodplain restoration and some public access facilities improvement, led by Alpine County with support from AWG and funded through California’s Integrated Regional Water Management program and Caltrans.
