      This database is current through 05/19/06, Register 2006, No. 20.

      s 135. Supplemental Standards for Butte Basin.

      The standards apply to Butte Basin, as delineated on Figure 8.12 and 
      partitioned into designated Areas B, C, D, E, and Reclamation District 
      1004. The basin's west boundary is the Sacramento River east bank project 
      levee, and above the Ord Ferry area where there is no project levee, the 
      boundary is the designated floodway of the Sacramento River adopted 
      November 29, 1988. The east boundary is based on the wetted area of the 
      1970 flood. The north boundary is the Sacramento River designated floodway 
      in the proximity of Murphy Slough and Golden State Island, and the south 
      boundary is the Sacramento River between the city of Colusa and the Butte 
      Slough outfall gates, a section of the Butte Slough levee in both Colusa 
      and Sutter Counties, and Pass Road in Sutter County. These standards 
      supplement and, where in conflict with, supersede the standards in section 
      111 through section 137.

      (a) Approval from the board is required for any encroachment that could 
      reduce or impede floodflows, or would reclaim any of the floodplain within 
      Butte Basin.

      (1) Encroachments in Reclamation District 1004 are not regulated by the 
      board.

      (2) The supplemental standards do not apply to that portion of Area E 
      located north of the Butte-Sutter County line and its extension westward 
      into Colusa County, and situated adjacent to the Sacramento River project 
      levee where the natural ground level is higher than the 100-year flood 
      elevation.

      (3) Except where the activity would potentially affect a project levee or 
      other project feature, the standards within sections 116, 122, 123, 124, 
      126, 127, 129, 130, 131, 132, and 137 do not apply to that portion of Area 
      E located south of the Butte-Sutter County line and its extension westward 
      into Colusa County.

      (b) Approval from the board is not required for crop checks less than 
      thirty-six (36) inches in height. In Areas B, C and D, all crop checks 
      must be removed prior to flood season, unless they comply with the 
      requirements of subdivisions (d), (e), and (f), respectively.

      (c) Except where the activity would potentially affect a project levee or 
      other project feature, approval from the board is not required for land 
      leveling or grading, or for drainage and irrigation improvements in Areas 
      C, D, and E that have a localized impact only and comply with subdivisions 
      (e), (f), and (g) of this section.

      (d) Within Area B, approval from the board is not required for any 
      encroachment that is less than eighteen (18) inches in height above the 
      natural ground level. However, any proposed encroachment within a slough 
      or swale must be approved by the board. Area B extends southerly from 
      Butte Basin's northerly boundary to a line located one thousand (1,000) 
      feet southeasterly and lying parallel to the Parrott Grant line.

      (e) Within Area C, approval from the board is not required for any 
      encroachment less than thirty-six (36) inches in height above the natural 
      ground level, and having a crest elevation less than seventy and one tenth 
      (70.1) feet (NGVD). Area C is the area enclosed within a three- (3) mile 
      radius measured from the center of Moulton Weir and limited by the 
      southeasterly extensions of the north and south training levee alignments 
      to the three- (3) mile arc.

      (f) Within Area D, approval from the board is not required for any 
      encroachment less than thirty-six (36) inches in height above the natural 
      ground level and having a crest elevation less than fifty-four and nine 
      tenths (54.9) feet (NGVD). Area D encompasses the Colusa Weir together 
      with its outflow channel enclosed by training levees, and an overflow area 
      extending to Butte Creek.

      (g) Within Area E, approval from the board is not required for any 
      encroachment less than thirty-six (36) inches in height above the natural 
      ground level. The northern boundary of Area E is a line located one 
      thousand (1,000) feet southeasterly of the south Parrott Grant line, and 
      the southern boundary is formed by the Sacramento River between the city 
      of Colusa and the Butte Slough outfall gates, a section of the Butte 
      Slough levee in both Colusa and Sutter Counties, and Pass Road in Sutter 
      County.

      (h) Within that portion of Area E located south of Gridley Road, new and 
      existing recreational structures, including caretaker, security, and 
      dwellings for seasonal occupancy (as defined in section 113) may be 
      permitted provided the finished floor level of the structure is at least 
      two (2) feet above the design flood plane or two (2) feet above the 
      100-year flood elevation, whichever is higher.
