Ayers Water Diversion, Stream Crossings, and Embankment Removal Project (Lake or Streambed Alteration Agreement No. 1600-2018-0731-R1)
The project is limited to six encroachments. One encroachment is for water diversion from an unnamed tributary to South Fork Bear Creek. Water shall be diverted for domestic use only. Work for the water diversion will include use and maintenance of the water diversion infrastructure. The second encroachment shall remove a disused
spring-box and all associated diversion infrastructure from the stream channel. Work for this encroachment will include excavation and proper storage or disposal of the infrastructure off-site. The third encroachment shall replace an undersized culvert and remove excessive rock armoring. Work for this encroachment will include excavation, removal of the undersized culvert and excessive rock armoring, replacement with a new properly sized culvert, backfilling and compaction of fill, and rock armoring only as necessary to minimize erosion at the inlet, outlet, and slope faces. The third
and fourth encroachments shall upgrade informal dirt ford crossings with appropriately designed armored fill crossings. Work for these encroachments will include excavation, removal of the fill material down to the natural streambed, realignment and recontouring of the natural channel, replacement with new properly sized rock, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion. The sixth encroachment shall remove a dirt embankment and paved spillway impounding the stream. Work for this encroachment will include dismantlement and
removal of the paved spillway, excavation and removal of the fill material comprising the embankment down to the natural streambed and banks, proper storage and/or disposal of the material off-site, and revegetation of the riparian area.
