Chatfield Reservoir Reallocation Project Environmental and Recreation Mitigation July 17, 2007 Conference Call Summary The EDA W Purchase Order has been approved and State Parks is ready to have them proceed on the 7,700 AF analysis. Additional adjustments will be made to the 20,600 AF alternative including updated costs. A final report will include all phases of the work for both alternatives. A 45-day completion is anticipated once EDA W begins work. The scope calls for evaluation of construction timing at the marina only, but not the entire recreation mitigation project. There will be analysis of potential impacts to recreation facilities, sites, and the environment. EDA W should provide Tetra Tech with GIS overlay information so that proposed recreation mitigation concepts/sites can be looked at with respect to environmental mitigation. A discussion took place regarding the handling and treatment of dead trees that will result from the reallocation. Studies by Tetra Tech will assist in determining the ability of various species to survive inundation based on frequency and duration. Acreages of trees will need to be estimated so that appropriate mitigation can occur. There are issues related to public safety (falling branches), aesthetics, fish habitat, birds (cavity nesters) that may not all be in harmony. State Parks issues will need to be integrated with environmental benefits of leaving dead trees in place. More work to be done on this topic. The Corps requested that TetraTech work with EDA W to ensure least environmental damaging "relocations" are pursued for State Park facilities. Timing for recreational mitigation construction was discussed. The issue was raised regarding phased construction to keep the park open during the regular season vs. faster construction be closing the park for a period of time while construction takes place. State Parks believes that closing the park is not an option due to political realities and park user sensitivities. The EIS should include a description of how the recreation mitigation will take place so that impacts can be more accurately described. The DNR Executive Director's office will need to become involved with issues related to CWCB, State Parks, and Division of Wildlife. State Parks will need to follow Corps LUDPs (land use development plans) and look at the various elevation zones for determining where facilities should be moved. The elevation zones are based on flood frequency (e.g. 10-year, 50-year, 100-year, etc.). There is a significant concern related to public perception of the impacts to the Chatfield State Park as a result of the reallocation process and the mitigation projects. It would be wise to engage the public early regarding recreational mitigation (prior to draft EIS going public) in order to provide some education and outreach. Discussions took place on how to best achieve the outreach goals, and State Parks offered to disseminate flyers/brochures at the park entrance. There does not seem to be an organized recreation/boating group in the same way that environmental interests have been assembled. Proactive education will be key with the need for viable ways to receive input and concerns.
