2 Citizen's Con2ressional Task Force on the New River 4151 Highway 86, Bldg 4 Brawley, CA PROJECT TRANSMITTAL TO: Citizen's Congressional Task Force on the New River FROM: Leon Lesicka DATE: June 5, 2002 SUBJECT: Reconnaissance Inventory of Wetland and Sedimentation Basin Sites New and Alamo Rivers, May 2002 Enclosed, for your review and comment, is a copy of the Reconnaissance Inventory of Wetland and Sedimentation Basin Sites, New and Alamo Rivers, May The purpose of this report was to provide an inventory of all potential wetland and sedimentation basin sites along the New and Alamo Rivers and, based on this invenfory, develop a preliminary cost estimate for total program implementation. In order to develop a basis for the program cost estimate, preliminary conceptual designs were generated. These concept drawings are not intended to represent a final design. In preparation for our "next steps," please review the report and provide your comments on both the report content and suggestions for future work tasks that can be completed to move the program forward during the demonstration project monitoring period. The information presented in this report is a launching point and, although this particular document will not be edited further, -and your comments are important input for shaping the future direction of the program. Please provide your comments by August 30, 2002 to Karen Holdsworth, IVES via at ives@integrity.com. As the Task Force moves ahead, I look forward to your input and insights. Page 1 of 1
