2. REGULATORY PERMIT REQUIREMENTS

SBCFCD has informed Valley District that letters of authorization or permits from California
Department of Fish and Wildlife (CDFW), United States Army Corps of Engineers (USACE),
and California Regional Water Quality Control Board – Santa Ana Region (RWQCB) will be
required to satisfy the Flood Control Permit Application for each of the seven sites within
the SBCFCD right‐of‐way. Valley District has been working with each regulatory agency to
comply with all applicable requirements.

2.1. SAN BERNARDINO COUNTY FLOOD CONTROL DISTRICT REQUIREMENTS

Valley District will need to submit a Flood Control Permit Application to SBCFCD for the
seven investigation sites within a SBCFCD right‐of‐way. A copy of the SBCFCD Flood Control
Permit Application is provided in Appendix A of this Work Plan. This Work Plan provides the
required description of proposed activities including maps showing proposed test infiltration
basin locations, access routes/layouts for equipment and water conveyance, and proposed
water sources (for sites where an available hydrant is confirmed). Options for temporary
storage of excavated soils either within existing storm channels or on channel banks may be
subject to SBCFCD requirements, which have yet to be determined.

2.2. CDFW STREAMBED ALTERATION AGREEMENT

California Fish and Game Code Section 1602 requires an entity to notify California
Department of Fish and Wildlife (CDFW) prior to commencing any activity that may do one
or more of the following:

 Substantially divert or obstruct the natural flow of any river, stream or lake;
 Substantially change or use any material from the bed, channel or bank of any river,
stream, or lake; or
 Deposit debris, waste or other materials that could pass into any river, stream or
lake.

Water bodies include those that are episodic (dry for periods of time). It is anticipated that a
streambed alteration agreement for the proposed testing would be approved by CDFW
under provision that any modification to the creek bed would be temporary and occur when
surface flows did not occur, and the sites would be returned to their pre‐disturbed grade
following completion of infiltration testing. A copy of the CDFW Notification of Lake or
Streambed Alteration Permit Application is provided in Appendix A of this Work Plan.

Valley District has been working with CDFW to ensure a final letter of authorization would
cover all seven SBCFCD sites as well as the six non‐SBCFCD investigation sites.
