<br />I . <br />! # <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />~ <br /> <br />an additional culvert crossing. Attempt to protect the left bank of the South Platte <br />River in the area where the new flood channel will daylight. The river bank is not <br />stable and tends to migrate during high flows. <br />4. Increase the capacity of the existing ditch located between the railroad and hwy 144. <br />The reach will start at CR 9 and continue east to the old railroad trestle. Provide large <br />box culverts for the road and driveway crossings of the ditch (4 total?). Protect the <br />drain tiles in the vicinity of the old railroad trestle with riprap or encasements. <br />5. Construct concrete spill structures on the Riverside Canal and the Weldon Valley Ditch <br />need to be constructed to prevent future bank failures. The ditch companies are <br />agreeable to this. <br />6. Widen the existing drain ditch that flows from north to south from the intersection of <br />CR Y and CR 10 to hwy 144. Purchase a strip of land on the east side of the power <br />poles to construct a shallow and wide ditch. Possibly increase the size of the existing <br />culvert at hwy 144. Construct a dip (Texas Crossing) on CR Y just to the west of CR <br />10. <br /> <br />· Acquisition costs for the farm land located to the south of hwy 144 are estimated to be <br />$1,800 per acre. <br /> <br />· Inundation and/or flood easements across farm lands could be estimated as a lump sum <br />payment of $300 per acre. <br /> <br />· There does not seem to be a good source of riprap anywhere in the project area. The ditch <br />company uses broken concrete. <br /> <br />· The County will provide money for some of the necessary land acquisition, and will provide <br />labor and equipment for a majority of the earthwork. The County would also like to trade a <br />piece of land for the small parcel located on the NW comer of CR 9 and hwy 144 so that it <br />does not have to be purchased. <br /> <br />· The Riverside Ditch suffered damages in the amount of $62,000 as a result of the flood. <br />$20,000 of that was not considered to be "eligible damages" according to FEMA. <br /> <br />Action Items: <br /> <br />· CWCB will set up a final review meeting for the end of January. The meeting should be held <br />on a Thursday, if possible, to accommodate the schedules of the County Commissioners and <br />staff. <br /> <br />· CWCB staff and County staff will attempt to contact the UPRR regarding work on the <br />railroad right-of-way. <br /> <br />. CDOT will provide cost information for bridges and culverts for recent highway work. <br /> <br />C:\seca\flood\weldona\minutes 1- 9.doc <br />
