<br />14. Existing Utility Conflicts. Utilities other than sanitary sewers <br />will be relocated as needed. Sanitary "ewer conflIcts will be <br />resolved on an Individual basis In fInal design. Utility field <br />surveys will be required prior to final design. <br /> <br />15. Existing Water Rights. ExIsting water rights will be protected, <br />as appropr I ate, Tnc Iud ing surface d i verl;l ons and un de rground seep- <br />age lines. Diversion dams to be built in channels as needed. <br /> <br />16. Initial Dralnaqe System. The storm sewers and other features of <br />the InitIal storm runoff system will be planned and constructed <br />so as to not significantly change the drainage basins. <br /> <br />17. Irrlqatlon Low Flows. The pr<esent regime of Big Dry Creek Is not <br />stable, with the channel presently down'..cutting and meandering. <br />To stabal ize the channel, low flow velocities should be limited <br />to 3 fps, using small checks as necessary with a maximum height <br />of 1.5 feet above the channel thalweg. In upper portions of the <br />basin where the checks would cause an increase In flood area, <br />concrete low flow controls shall be installed flush '11th the channel <br />bottom, and the channe 1 will be a 11 owed to con t I nue to e rode to <br />a more stable slope, rather than artificially excavating the channel <br />to a stable slope. Construction impacts are to be I imited only to <br />the selected areas around the eros Ion controls. In the lower <br />reaches of the bas In there ar,e numerous areas where the channe I <br />slope Is presently stable at low flows. To provide erosion <br />control for frequently occurlng storms, gablon erosion controls <br />shall be constructed on grade as needed on about 1,000 foot Intervals. <br /> <br />v 1-6 <br />
