will also be required to submit a technical revision with appurtenant bonding <br />requirements to fulfill its conversion to a wetland mitigation area. <br />Elam Construction, Inc. also holds title to the property sufficient to record the proposed <br />deed restrictions identified in Appendix B. In addition to the proposed deed <br />restrictions; Elam Construction, Inc. owns the necessary water rights required for the <br />establishment of wetland and aquatic habitat on the property. <br />V. IMPLEMENTATION PLAN <br />A. Rationale for Expecting Implementation Success <br />The selected mitigation site includes desirable characteristics that make it suitable as a <br />mitigation area: (1) the site can be graded such that the ground water is within a foot of the <br />soil surface, (2) the site has access to supplemental irrigation if needed, (3) the site is located <br />in an area that can be separated from other activities and should be much less vulnerable to <br />unanticipated disturbances, and (4) the site is located adjacent to the flood plain of the <br />Yampa River and will visually blend with the vegetation of the flood plain. <br />WWE and WWE's employees have extensive experience in designing wetland mitigation <br />sites in western Colorado. Examples include the Plateau Creek Pipeline wetland mitigation <br />site; many small mitigation sites for road crossings, pipeline crossings, and facility sites; and <br />wetland mitigation banks that require conversion of uplands to wetlands. WWE recognizes <br />the critical need to understand the hydrology of a site and the need to design wetlands for the <br />hydrology of a site rather than to try to change or create hydrology. In our experience, <br />wetland soils typically develop on sites with wetland hydrology. Most irrigation ditches <br />begin to develop wetland soil characteristics (anaerobic conditions, gley colors) within a few <br />years of first use. <br />B. Responsible Parties <br />1. Elam will be responsible for all construction activities, WWE will be on site during all <br />phases of construction to oversee all aspects of final grading and planting. <br />C. Site Preparation <br />1. Excavation and re -grading around the water surface edges will be a minimum of 100 <br />feet from the Yampa River. The applicant will install all pertinent erosion and <br />sedimentation controls prior to any surface disturbances. Silt fences, straw bales <br />and/or berms will be erected around the mitigation area so that there will not be a <br />release of sediments during storm events. Site storm waters will be handled as <br />specified in the Storm water Management Plan (SWMP) for the site (Appendix D). <br />2. Suitable topsoil will be stripped from around the existing open water area. Stockpiles <br />of topsoil will be established east of the project area. All topsoil material will be <br />stripped and stockpiled using bulldozers, motor graders, tracked excavators and front- <br />end loaders. <br />3. Samples of topsoil will be sent to Colorado State University (CSU) Soil Laboratory to <br />be analyzed for suggested amendments. <br />WestWater Engineering Page 12 of 24 July 2012 <br />
