Everything finally came together and we were able to start construction on Peak Reservoir Reconstruction in August of 2011. B. Blanche Park Reservoir: While Peak was under construction, Blanche Park became the next focus for reconstruction. The first thing to be accomplished was determination of the access. All original roads had either been removed or been overgrown with new forest growth and access was difficult to determine. As with Peak, Blanch Park is located within the USFS jurisdiction and any access would be coordinated with them. In the summer of 2011, altemate routes had been determined in the field by the District and survey firm. The USFS was contacted for their concurrence. After walking the proposed route with the USFS representative, the route was rejected and another route was needed to be found. By the time the decision by the USFS was released, the winter storms had arrived and an opportunity to find another route was put off until the following year. As soon as the snow melt, a new route was walked with the USFS representative, of which they tentatively agreed. The new route as surveyed and the design was presented to the USFS. The new route was about the same length (approximately 1,200 ft) as the original but it presented less environmental concern. A new survey was preformed and design of the access was began and submitted to the USFS in January 2012. While this work was being completed, the soils engineer, environmental firm and civil engineer were working on the design of the reconstructed embankment An access permit was necessary from the USFS for the soils firm to "walk" their soils testing equipment onto the site. That was secured and all testing was begun. The environmental firm had also delineated the wetlands within Blanche Park and along the proposed access. The design worked around the wetland concerns and mitigation was determined to not be required. Because of the excess of embankment material from Peak, the District and engineer determined that it would not be necessary to "mine" any material from the upstream side of the Dam. That decision eliminated the requirement for a 401 permit. The design of the Dam reconstruction started in earnest in November 2011 and was submitted to the Dam Safety representative March 2012. The plans were reviewed and comments received by the civil engineer in October 2012. Revision had been made and resubmitted January 2013 to both the Dam Safety and USFS for their comments on the embankment and access road, respectively. All wetland delineation is approved and no environmental concerns outstanding. All documents should be approved prior to the spring runoff and construction started in July of 2013. 13
