1-4 In this case the levees should meet the National Engineering Standards for Dikes and Levees, the pumping capacity should be adequate for the design runoff, and the outlet into which the pumps discharge should meet the basic requirements for outlets. e Legal Requirements Applicable provisions of state water laws must be met in all channel work. Existing water rights may require protection or rebuilding of diversion works, control structures for regulating flows, etc. Preliminary investigations should determine the existence of any water rights on channels to be improved and the limitations that they may impose on the improvements. Rights-of-WaV Acquisition of rights-of-way is an essential element of channel improvement. Careful consideration of this element from the preliminary investigation or reconnaissance stage through the construction stage will greatly expedite the job and reduce its cost. Certain modifications of location and alignment, within the limits of good design, may be made to ease rights-of-way problems. Landscape resources shall be given full consideration from the preliminary investigation through final inspection. These resources include visual, fish, wildlife and recreational and may include areas outside of the right-of-way that are affected environmentally as a result of the project. A guide for planning and design considerations related to wildlife, fish and recreation resources may be found.in Chapter 7. e Environmental Considerations A guide to visual resource data needed in planning and design may be found in Chapter Z, Appendix A. Visual changes in the landscape that result from channel work should be examined. The before and after appearance of the site should be documented and discussed with the local community and other interested individuals or groups. Procedures discussed in Chapter 8 shall be used for designing the visual resource. e
