<br />" <br /> <br />'.' <br /> <br />Design and Construction <br /> <br />Chapter 3 of the FR Supplement (Reclamation, 1984), entitled "Development of Designs and <br />Estimates" provides updated design infonnation from that used for the 1984 Plan. The <br />Frontispiece map shows the laterals and canals recommended for piping. Specific data for <br />each system (length, capacity, pipe size) used in this EA is in Attachment B. The next <br />section discusses environmental protection measures for design and construction activities. <br /> <br />The cooperative agreement for funded proposals should provide for an interdisciplinary team <br />to prepare designs, coordinate plans with affected landowners, oversee installation of the <br />pipelines, and coordinate with appropriate entities for habitat replacement needs. <br /> <br />Lands and Rights-or-way <br /> <br />The 1984 Plan assumed the existing alignment of canals and laterals would be used when <br />lining the canals and laterals. This would eliminate the need for new land interests, except <br />temporary access requirements for construction. For funded pipelines, the design team <br />would contact landowners about realignment and rights-of-way needs. Designers would <br />evaluate options to reduce lateral system mileage and increase efficiency by combining <br />laterals or changing alignments. Preliminary evaluations have reduced pipeline lengths from <br />202 to 188 miles. Estimates for realignments anticipate less than 500 acres of rights-of-way <br />would be needed. <br /> <br />Land interests for habitat replacement lands would be purchased from willing sellers at fair <br />market values. <br /> <br />Protection of Facilities <br /> <br />Both the 1984 Plan and the East Side Laterals Project call for replacing all crossings, <br />turnouts, cross-drainage facilities, and other structures impacted by reconstruction activities. <br />This includes about 37 existing county road crossings and 228 farm road crossings. Fences <br />and gates of landowners along the laterals would be replaced where they occur on present <br />alignments. If laterals are in pipe, many fences required by the 1984 Plan to derme the <br />rights-of-way and reduce hazards of open ditches would not be needed. Each lateral would <br />originate from a gated and screened canal turnout (about 42 structures). They would include <br />a concrete transition at the outlet of the turnout pipe, a stilling pool and a measuring device. <br />Pipelines for gravity systems would follow existing, or possibly new, alignments. Existing <br />turnouts along the laterals (about 1,002 structures) would be replaced at existing flow <br />capacities, unless changes are mutually agreed upon by the design team and landowner(s). <br /> <br />8 <br />
